Every apostle knows that there is an upper world above the continent. However, even the most capable flying magical beasts can't reach the Spirit Realm even if they fly upward for tens of thousands of years.

  As far as Chen Yue knows, at present, only apostles can reach the Spirit Realm, and they can only do so when summoning familiars. However, even they don't know the exact location of the Spirit Realm.

  Unexpectedly, in the Trial Ground, one can see the Spirit Realm so clearly.

  Sure enough, it truly lives up to its reputation as the most special and mysterious place on the continent.

  "Hoo."

  After staring Obsession ly at the otherworldly Spirit Realm for a while, Chen Yue withdrew his gaze. After taking several deep breaths, his expression calmed down and regained its calmness.

  "So that's how it is. The Trial Ground is so close to the Spirit Realm. Although I don't know what the glassy sky that separates the Spirit Realm and the Trial Ground is, the Trial Ground should also be affected by the Spirit Realm, making the environment here somewhat similar to that of the Spirit Realm. Although I can't tell the difference, familiars definitely can. It's precisely because of this joy of returning home that the Blade Beast burst out with power."

  After thinking for a moment, Chen Yue understood and also knew why Vinia said that the environment here was very important.

  The environment in the Trial Ground, which is similar to that of the Spirit Realm, can make familiars feel happy. Moreover, it's not as extremely harsh on apostles as extreme environments are. Apostles can't survive in the extreme environments that familiars like, but they have no difficulty here. This solves the biggest difficulty in improving compatibility. As long as one keeps fighting in the Trial Ground, one can definitely improve the compatibility between each other.

  Although the effect may not be as good as that in extreme environments, it's still a shortcut. After all, compatibility is the biggest problem that troubles all apostles.

  "The environment of the Trial Ground is also very useful for me. If I still want to continue to improve the compatibility with the Frozen Rabbit, I need to go to a colder environment. However, with my current body that has only undergone the second transformation, I can't do it without the help of props. And using props won't help improve the compatibility," Chen Yue thought.

  "Well, this year, I not only have to strive to improve the compatibility with the Blade Beast to above 'familiarity', but also try my best to improve the compatibility with the Frozen Rabbit. I just don't know what's above 'intimacy'."

  After calming down, Chen Yue decided that if there was no danger, he would keep the Frozen Rabbit outside all the time.

  Just as Chen Yue was about to set off again, Meteorite Crystal suddenly shouted again.

  "Wait a minute, Chen Yue."

  "Meteorite Crystal, can you finish everything at once..." Chen Yue was speechless.

  Rolling her cute eyes, Meteorite Crystal said innocently, "Woo, I didn't know either. It's all because your mentor always wrote the information in paragraphs."

  Chen Yue was speechless when he heard this. Anyway, he couldn't understand it himself, and the little guy was always right no matter what she said. There was nothing he could do if she wanted to deny it.

  "Go ahead."

  Meteorite Crystal giggled and said, "Go and check that Prime Beast. There should be something called Life Essence left behind."

  She pointed in the direction of the remains of the Prime Beast with her back turned, then quickly withdrew her hand and didn't dare to look back at all.

  Chen Yue walked over as he was told. This Prime Beast was killed so thoroughly that it looked like a pile of chopped pork. After rummaging through it without changing his expression, Chen Yue indeed found a chip the size of a finger. It should be the Life Essence that Meteorite Crystal mentioned.

  This crystal-clear Life Essence was a light milky white, without any trace of blood on it. Moreover, under such heavy pressure, there wasn't even a trace of being broken. It was definitely much more precious than magical beast crystal cores and the like. Perhaps even something as hard as energy crystals might not be able to be preserved intact under the force of tens of thousands of catties.

  "What's the use of this thing?"

  After walking back, Chen Yue spread out his left hand and asked while looking at the chip in his palm.

  Meteorite Crystal flew over and curiously looked at the chip that was about the same size as her. Obviously, she was also very curious. However, this was the first time she had even heard of the Trial Ground, let alone the Life Essence, which was clearly a product of the Trial Ground.

  Later, Meteorite Crystal's eyes turned a little red, and she actually activated the True Vision Pupil to directly observe the essence of the Life Essence.

  "Huh, I really can't understand its essence."

  After a while, Meteorite Crystal gave up dejectedly and said listlessly, "This thing, together with the Prime Liquid and the Prime Crystal, is known as the three greatest treasures in the Trial Ground. However, the Prime Liquid is only effective for apostles, the Life Essence is only effective for familiars, and the Prime Crystal is a bit more advanced and is effective for both."

  "Oh?"

  This was the first time Chen Yue had heard of this. Come to think of it, among the so-called three greatest treasures, except for the top-level Prime Crystal, he had already seen the other two.

  "Let's give it a try. I'll ask Sister Ice what effect it has," The little guy suddenly became interested.

  Chen Yue nodded. He was also a bit expect.

  He handed the chip to the Frozen Rabbit.

  At first, the Frozen Rabbit wasn't very interested. However, after sniffing it, the joy in its red eyes was so obvious that even Chen Yue could sense it. It quickly took a bite, chewed it a few times like eating candy, and then swallowed it. After that, an extremely satisfied expression appeared on its face.

  "What good teeth! It can even bite through the Life Essence core, and this Life Essence is the same..." Chen Yue even suspected that the Frozen Rabbit's most powerful ability was its teeth...

  The author's narrative has been misappropriated; report any instances of this story on Amazon.

  "How is it?" Chen Yue looked at Meteorite Crystal.

  The little guy communicated with the Frozen Rabbit. After a while, she said somewhat blankly, "Sister Ice said she has become a bit stronger."

  Although Meteorite Crystal can communicate with familiars, the expression is still very limited. It's good enough to barely understand the meaning.

  "Stronger?" Chen Yue was a bit puzzled when he first heard it, but then he had a flash of inspiration and understood.

  "So that's it. This Life Essence can improve the level of familiars."

  After figuring this out, Chen Yue couldn't help but beam with joy.

  Chen Yue had leveled up so quickly. In just over a year, he had reached the second level, and even used the Prime Liquid to reach the point close to the bottleneck of the second level. His speed was so fast that it would make any apostle dumbfounded.

  With rapid advancement, although the foundation of the source of life is extremely solid and there won't be any problems, as time passes, a problem gradually emerges.

  That is the level of familiars.

  You should know that the strength of familiars is calculated by star level + level. After being summoned down, except for special ones like the Blade Beast, no matter how powerful the familiars are, they will be suppressed to the first level. The Frozen Rabbit is like this.

  Most familiars can't improve their star levels, but their levels can be improved. Although the level of familiars can't exceed the level of apostles, the advancement of familiars is also extremely difficult. They can only rely on the accumulation of time to slowly level up, which is not much different from the difficulty of apostles' advancement, so it's not a problem in general.

  However, in Chen Yue's case, it's a big problem. The advancement speed of the Frozen Rabbit is far slower than his, so it's still at the first level at present. If Chen Yue's leveling-up speed remains so fast in the future, this problem will become even more serious.

  After all, the strength of apostles mainly depends on familiars. If familiars' strength doesn't increase quickly, what's the use of apostles having a high level?

  However, at this moment, the appearance of the Life Essence is like a bright light in front of Chen Yue. If all Prime Beasts possess Life Essence, then as long as a large number of Prime Beasts are hunted, the strength of familiars can be quickly improved.

  "The Life Essence is useless for the Blade Beast, but it's extremely effective for the Frozen Rabbit. Well, no wonder so many people are desperate to get in here."

  After understanding the special features of the Trial Ground, Chen Yue finally understood the significance of this place for apostles.

  Meteorite Crystal also added that the trial results also depend on the harvest of the Life Essence. Whoever has the largest quantity and the highest quality of Life Essence will undoubtedly have better trial results.

  "Alright, let's go to the Trial City first. After registering, we'll come out immediately to hunt Prime Beasts and improve our strength as soon as possible."

  Just as Chen Yue was about to leave, he suddenly stopped in his tracks and looked at Meteorite Crystal with some vigilance:

  "Do you have anything else to say?"

  "Chen Yue, look at what you said," Meteorite Crystal said pitifully. However, the next moment, she changed her tone and said, "But there really is..."

  Chen Yue was speechless, but then he became serious.

  Meteorite Crystal had already introduced most of the information given by Vinia. Then, what was left was probably the usage of the Glassy Bead.

  "I remember both Vinia and that deacon said that the Glassy Bead is very useful in the Trial Ground," Chen Yue recalled.

  Sure enough, Meteorite Crystal said, "There's also the Glassy Bead. Your mentor said that it can indicate the number and grade of Prime Beasts within a kilometer."

  "Really?"

  Looking up in disbelief, Chen Yue never expected that the Glassy Bead had such a function.

  Although it doesn't have powerful destructive power, its function in the Trial Ground is far more important.

  Meteorite Crystal nodded very definitely, then took out the Glassy Bead and threw it into Chen Yue's hand.

  When he was in the Trial Hall, Chen Yue had also tried to figure out the function of the Glassy Bead, but all his attempts ended in failure. The Glassy Bead had always been unresponsive. However, after entering the Trial Ground and sensing the environment here, the Glassy Bead immediately changed.

  There was nothing on it at first, but Chen Yue already understood that it was probably because there were no Prime Beasts within a kilometer. After walking several hundred meters in the direction of the Trial City, some green dots appeared on the edge of the Glassy Bead.

  "According to Vinia's introduction, green dots should represent second-grade Prime Beasts."

  The Glassy Bead wasn't big, but Chen Yue's eyes were sharper, so it didn't prevent him from seeing the situation clearly.

  After carefully sneaking in one direction, Chen Yue indeed saw two strangely shaped second-grade Prime Beasts playing leisurely. Obviously, they hadn't noticed Chen Yue's arrival.

  "Second-grade Prime Beasts. It shouldn't be too difficult for me."

  Chen Yue's gaze suddenly became sharp. After giving the Frozen Rabbit the order to attack later, he exerted force on his feet and immediately shot out like an arrow leaving the bowstring. Before the two Prime Beasts could react, the Blade Beast stabbed one of them, and at the same time, the Frozen Rabbit also jumped out and froze the other one with a freezing breath.

  The strength of these two second-grade Prime Beasts wasn't strong, but the stalemate in the battle was beyond Chen Yue's expectation. Their attack power was indeed not strong, but their destructive power was beyond Chen Yue's imagination.

  Perhaps it was because of the special environment of the Trial Ground.

  Once injured, their wounds would heal quickly at a visible speed. Even if their legs were broken, they could still walk briskly after a while. Their toughness was really rare.

  It took a lot of effort for Chen Yue and the Frozen Rabbit to defeat them.

  After digging out the smaller Life Essence, Chen Yue fell into deep thought.

  After this battle, he had a clearer understanding of the strength of Prime Beasts. It seemed that the characteristic of Prime Beasts was to be tenacious. As long as you couldn't kill them in one blow, then with their powerful recovery ability, the longer the time passed, the more disadvantageous it would be for you.

  "Looks like it was really lucky that I could kill that third-grade Prime Beast in one blow."

  Thinking of this, Chen Yue felt a bit scared.

  Perhaps the Blade Beast's cutting ability could easily deal with second-grade Prime Beasts, but it was sealed, and unsealing it would cause even bigger problems. Chen Yue could only think of other ways.

  "Well, reach the Trial City as soon as possible, complete the deal with West, and after reaching the third level, I can use the trick set by Meteorite Crystal to unseal the Blade Beast. By then, it should be easier to deal with them."

  Chen Yue was deep in thought. Judging from the strength shown by these two second-grade Prime Beasts, the periphery of the Trial City was indeed a dangerous area. If one was careless and couldn't solve the Prime Beasts immediately and got entangled, no matter how strong one was, there was only one outcome - death.

  At this time, Chen Yue's mentality also had a subtle change. He planned to reach the third level as soon as possible instead of continuing to hunt Prime Beasts.

  After making up his mind, Chen Yue started to rush towards the Trial City. Along the way, relying on the miraculous effect of the Glassy Bead, Chen Yue tried his best to avoid large numbers of Prime Beasts. When it was really unavoidable, he would choose the weakest first-grade Prime Beasts to break through.

  In this way, by the time he passed through the dangerous area, the number of second-grade Prime Beasts that died under his hands had exceeded twenty, and the number of first-grade Prime Beasts was nearly a hundred.

  It took a day and a half, a bit later than planned, but Chen Yue finally arrived at the Trial City.
