Ye Qiuhan, Tik, and Chen Tuan also relaxed at this time, this wave of demon invasion survived, and they could be regarded as fighting for nearly eight hours in a row, although they didn't need to fight the demon monsters head-on, but they already felt tired after fighting for so long.

However, after Xiao Li posted the information of "free activities" in the legion channel, Ye Qiuhan and Tik still rushed out of the Butterfly Valley quickly, and enthusiastically went to hunt the scattered demon monsters, only Chen Tuan was a little uncomfortable, but ran to the temporary camp of the people to eat barbecue.

After Xiao Li rested a little, he also led his large army to start clearing the remaining big-mouthed demons everywhere, and at this time he was quite relaxed, so he took out three pieces of demon hearts and studied them.

[Demon's Heart (Bigt/Litstan/Kakira): A mysterious thing with great power, faintly related to the demon Byatt/Litstein/Kakira. 】

The three demon hearts look much the same, and the attribute introductions are extremely simple, and they don't see any use at all.

However, since it is a system reward, and it is obtained by killing the three-headed demon leader BOSS, there must be something extraordinary, and Xiao Li still attaches great importance to them. Relying on the experience of the closed beta, Xiao Li felt that this demon heart was likely to be a "gem-type" functional prop, just like the Vulcan Stone.

[Vulcan Stone: A stone containing powerful fire power, a type of elemental gem. 】

The attribute information of this Vulcan Stone is also extremely simple, and it is literally useless at all, but it can be used to cultivate the "Flame Tank" and promote it from Tier C to Tier B.

The mysterious player who discovered the "Flame Tank" cultivation route in the internal test is also really powerful, and the ghost knows how he found out that the Vulcan Stone can be used like this, but this discovery undoubtedly gave Xiao Li a lot of inspiration.

"The Vulcan Stone contains the power of flames, which can make the flame tanks with flame power advanced, but it is also suitable, so will the Demon Heart also make some demonic monsters advanced? However, the Demon Heart is definitely much more precious than the Vulcan Stone, and if it involves the three-headed BOSS-level Demon Leader, maybe there will be an even more powerful effect......" Xiao Li's thoughts gradually drifted away, and he thought of a lot.

Suddenly, his eyes lit up, and he remembered the attribute information of the ghouls, big-mouthed demons, and red-eyed demons, among which there was an obvious hint: there was a promotion potential!

This is also described in the Flame Tank's stat information.

This is the attribute information given directly by the system, what does it mean? It means that these three kinds of monsters have the potential to be cultivated!

Then Xiao Li's mind flashed with inspiration, and he thought about whether these invading demon monsters could be captured with taming collars?

"Maybe it's possible, just give it a try!" Xiao Li became interested, and it just so happened that he bought a batch of tame collars from Tik, of which there were twelve D-rank ones, and he could also catch the Bigmouth Demon.

So Xiao Li got busy again, relying on the hunting net ridden by the wolf, it was too easy for him to catch the big-mouthed demon, and soon he grabbed one, and after ravaging it to half death, he began to throw out the D-rank taming collar, but all five times in a row failed, and the five taming collars were broken and lost.

However, Xiao Li was not discouraged, but his eyes gradually brightened, because the system did not give him a hint that he could not catch the big mouth demon, he continued to try, and he succeeded on the sixth attempt!

"System Prompt: Congratulations on successfully catching a level 20 Bigmouth Demon!"

"That's good!" Xiao Li raised his eyebrows, both surprised and delighted, this successful capture also made him know more about the demon invasion.

"These invading demons are probably between hostile classes and wild monsters, which is interesting!" Xiao Li was thoughtful, and he was in high spirits for a while, and he went around to catch the big-mouthed demon again.

As a result, the twelve D-rank taming collars were all used up, and he actually managed to capture two heads, which was not bad, and then dripped blood on the taming collar, and there were two more big-mouthed demon pets.

And as soon as the Bigmouth Demon turned into his pet, Xiao Li could see more information about them.

[Big Mouth Demon: Level 20, D-rank demon system, accelerated health recovery speed when in a barren dead land, level cap 20, with D-level physique and D-level combat instinct, with natural skills: meat bullet collision, devouring, with promotion potential. 】

[Meat Bullet Collision: The Big Mouth Demon turns into a meat ball and quickly rolls forward and collides, with no distance limit, and the physical defense and magic resistance are slightly increased during the transformation into a meat ball. 】

[Devour: The Bigmouth Demon can directly swallow small units (including elemental creatures, mechanical units, puppet summons, etc.) that are no higher than their own rank and level, and quickly digest them. Passive Effect: Largemouth does not need to consume food reserves. 】

Decent attributes, not strong or weak, it is worth mentioning the skill of [Devouring], which is equivalent to a second-kill skill for low-level mobs, but unfortunately the rank of the big-mouthed demon itself is slightly lower.

After successfully obtaining two level 20 big-mouthed demon pets, Xiao Li took out three demon hearts again, and he wanted to see how the demonic pets reacted to these three demon hearts.

As a result, as soon as the two big-mouthed demons saw Biat's demonic heart, they immediately became impatient, and their four little short legs kept upside down, and their bodies spun in place, and their eyes were dumbfounded, and they clearly wanted to take it for themselves.

"What a reaction!" Xiao Li was taken aback.

There are too many unknown settings in "Fantasy World" that players need to explore on their own, and if you can discover one or two secrets, it is undoubtedly equivalent to going ahead of other players and making a lot of money, such as discovering the cultivation route of the "Flame Tank".

However, the process of discovery must be accompanied by risks, it is possible to make money and more likely to lose, and now Xiao Li is facing such a choice.

Do you want to feed Biat's Demon Heart to a Big-Mouthed Demon? Or do you want to keep it and wait for more information about the Demon Heart to be used later?

If it is fed, maybe the Big Mouth Demon will undergo some changes, which can allow Xiao Li to guess some of the functions of the Demon Heart.

But it's also possible that the Demon Heart is not used to cultivate pets at all, and feeding the Bigmouth Demon is a waste.

However, Xiao Li didn't dwell on this issue for too long, he had three demon hearts, and he was willing to take out one of them to test it, so as soon as his mind moved, he threw Biat's demon heart into the mouth of a big-mouthed demon.

The big-mouthed demon was very excited, and after swallowing Biat's demon heart, his fat short tail shook, but then he curled up and turned into a meat ball, and his body quickly shrank, and his appearance formed a jade hard shell, and finally turned into a pet egg the size of a basketball!

"This ......"

Xiao Li's eyes narrowed, and he immediately checked the status information of this big-mouthed demon.

[Big Mouth Demon: In the free evolution of class transfer, the compatibility with the Demon Heart (Biat) is 62%, the success rate of promotion to Tier C is 100%, the chance of promotion to Tier B is 100%, and the chance of promotion to Rank A is 62%. If you successfully advance to Tier A, you will have a 62% chance to obtain Bronze, Ghoul Transfiguration, and Concussive Shockwave, each of which are unique to Biat, but cannot be obtained from the Leader Mark. 】
