In Chu Dongtian's palm, the heart core from the Mangniu Royal Clan released a faint earthy yellow halo, which looked charming. In addition, Chu Dongtian could clearly feel that there was a powerful force fluctuating back and forth in the heart core of this demon beast.

"As for it? It's just a small mountain realm demon beast heart core, what's there to look at in a daze? Why don't you hurry up refining and turn into real strength when you have this time? Besides, you idiot, have you forgotten what I told you, the demon beast heart core will constantly release a unique aura of demon beasts, and this breath is very easy to attract other demon beasts? You must know that humans can absorb the power in the heart core of demon beasts through secret methods, and demon beasts can do the same! Are you stunned and waiting for death?"

"I ...... Hehe, stop the anger and stop the anger, I'll start now!" said that it was the beginning, of course Chu Dongtian would not be stupid enough to refine the demon beast's heart core in place, so he had to find a relatively secret place.

After more than half an hour, Chu Dongtian finally found a suitable dilapidated small cave, disguised the cave a little more, and Chu Dongtian sat down cross-legged. Immediately after, Chu Dongtian opened his mouth, and with a flip of his palm, the demon beast heart core of the Mangniu Royal Clan entered Chu Dongtian's mouth with an afterimage.

Chu Dongtian didn't dare to slack off, according to the guidance of the Martial God Lifesource Spirit Flame, the mountain of Yuan Qi in his body shook violently, and an incomparably pure Yuan Qi rose from the dantian, rushed into Chu Dongtian's mouth in the blink of an eye, and then completely wrapped the reckless bull heart core in Chu Dongtian's mouth.

Strange to say, the heart core of the mangniu, which was obviously extremely hard in his hand, when it was wrapped in the pure vitality in Chu Dongtian's mouth, actually began to melt immediately, and a drop of earthy yellow liquid fell down Chu Dongtian's throat into Chu Dongtian's dantian.

Chu Dongtian had already made preparations, and when the first drop of heart core liquid fell into the dantian, Chu Dongtian's Lock Yuan Gong immediately urged, and the three mountains of Yuan Qi burst out at the same time with a powerful devouring force and rushed towards the first drop of heart core droplet.

The drop of heart core liquid trembled wildly under the action of the three devouring forces, and then a powerful resistance force actually rose inside the droplet, so that the three Yuan Qi Mountains in Chu Dongtian's body actually did not devour the heart core droplet in a short period of time.

In the midst of the stalemate, droplets of the heart nucleus continued to fall above, converging with the first drop of heart core fluid from before. In this way, although Chu Dongtian dissolved all the demon beast's heart core into heart core droplets, he couldn't really refine it for a while and swallow it inside the Mountain of Yuan Qi.

Chu Dongtian had already received the guidance of the Martial God Lifesource Spirit Flame, and knew that this was what it was like to be normal, and everything was nothing more than a trace of the remnant will of the reckless cow hidden in the droplet of the heart core. When the remnants of the reckless bull's will are worn out, it will come to fruition.

Of course, it was impossible for Chu Dongtian to waste too much time waiting, so Chu Dongtian decided to speed up the stimulation to make the remnants of the reckless bull's will perish faster. It's just that this kind of stimulation will also bring some risks to Chu Dongtian, after all, Chu Dongtian's own cultivation is also only in the early stage of Chengshan, and he has never done such a thing before. Otherwise, the Martial God Lifesource Spirit Flame would not have suggested that Chu Dongtian start with the demon beast heart core of the Sea Realm.

It's a pity that for a few days in a row, Chu Dongtian didn't touch the Demon Beast Royal Clan of the Huahai Realm, and finally bumped into the Mangniu Royal Clan of the Chengshan Realm, so why don't you give up?

"Time is not waiting, then ......" Chu Dongtian exhaled a breath of turbidity slightly, and a touch of ruthlessness and determination flashed in his half-open and half-closed eyes.

"Refine!" came out, Chu Dongtian mobilized his own thoughts, and shrouded the masses of heart core droplets with the power of his thoughts. In addition, Chu Dongtian was also madly urging the Mountain of Yuan Qi, making the devouring power that gushed out of the Mountain of Yuan Qi even more powerful.

Under this double impact, a strange scene happened. The liquid of the heart core of the reckless cow was violently twisted, not only did the resistance force become stronger, but at the same time, a reckless cow phantom appeared in the sky above the heart core droplet.

The reckless bull phantom opened its mouth angrily, the cow's head was slightly lowered, and the sharp horns pointed directly at the top of Chu Dongtian's dantian.

In the next second, the four hooves of the Mangniu Phantom stepped into the air, and it actually rose into the air, going all the way up along Chu Dongtian's dantian, trying to break into Chu Dongtian's head and destroy Chu Dongtian's sea of knowledge.

Although Chu Dongtian said that he was extremely talented, in the final analysis, he had only initially stepped into the door of martial arts, and what he had really come into contact with so far was only the normal cultivation method of physical vitality. For the most mysterious sea of knowledge in the human body, Chu Dongtian has not yet dabbled in it. If Chu Dongtian's mind was really collided by the remnant will of the reckless cow, even if the remnant will of the reckless bull was just a random impact, just driven by the instinct in the underworld, it would also bring great harm to Chu Dongtian.

At worst, he will be insane, and if he is serious, he will die in chaos!

On the contrary, if this Mangniu Royal Clan only had the Huahai realm during his lifetime, then his soul power would be relatively weak, and the residual will he could leave behind would obviously not be as good as the living Chu Dongtian, and it would almost be difficult to impact Chu Dongtian's sea of consciousness.

But then again, the demon beast heart core of the Sea Transformation Realm will be much less helpful to Chu Dongtian.

It was too late to say that it was too fast, seeing that the imaginary and real reckless cow phantom jumped upwards sharply, Chu Dongtian immediately frowned, and a stronger power of thought erupted and fell fiercely from above.

In the next second, the phantom transformed by the will of the reckless cow and the power of Chu Dongtian's invisible mind shook together, Chu Dongtian only felt that his head was splitting in an instant, and his whole head seemed to be hit by a giant hammer.

But fortunately, Chu Dongtian came prepared, and controlled this impact outside the sea of knowledge, so Chu Dongtian's sea of knowledge was only violently shaken, but the real trauma was not much.

On the contrary, the reckless bull phantom became much dimmer under this impact, and the momentum of the original upward jump was also severely contained.

Not only that, when the instinctive will collision was strongly hindered, the mass of heart core liquid droplets that had originally blocked the devouring power surging from the Yuan Qi Mountain also rippled layer by layer, as if a part of the power had disappeared in an instant, and a few drops of the heart core liquid were separated from it, and were absorbed by the three Yuan Qi Mountains of Chu Dongtian respectively like arrows from the string.

Don't look at it as just a few drops of the liquid of the heart core, but the liquid of this heart core is completely worthy of the Martial God's lifesource spiritual flame's admiration for Chu Dongtian. When Chu Dongtian's three Yuan Qi Mountains each swallowed one or two drops, those few drops of Heart Core liquid instantly dispersed inside the three Yuan Qi Mountains, turning into extremely pure and rich Heaven and Earth Yuan Qi.

Then, under the power of the Mountain of Vitality, these Heaven and Earth Yuan Qi liquefied again, and after liquefaction, they turned into a solid form, filling the empty interior of the Mountain of Yuan Qi. On average, every drop of heart core liquid is the size of a fist when it is finally transformed into a mountain of vitality!

You must know that under normal circumstances, if Chu Dongtian relied on his own absorption of Heaven and Earth Yuan Qi to transform it into the same scale, it would take at least half a month or even a month!

"A drop of heart core liquid can be turned into a fist-sized drop, and this mass of heart core droplets is roughly a hundred drops, plus the refining speed is extremely fast, doesn't it mean that I only need to refine all the heart cores of this mountain realm Mangniu royal clan, which is equivalent to cultivating normally in the outside world for four years or more?"

"The only thing that is difficult is that the Demon Beast Royal Clan is not so easy to encounter, and with my current ability, I can only attack the Demon Beast Royal Clan in the Chengshan Realm at most, if it is beyond the Chengshan Realm, not to mention that the head-to-head confrontation is far from being defeated, even the impact of the residual will is estimated to be difficult to withstand!" Chu Dongtian shook his head, which was almost cracked by the impact of the remnant will of the reckless bull, and secretly spoke.

No matter what, Chu Dongtian quickly got rid of the distractions that he shouldn't have and continued to refine.

And at the same time that Chu Dongtian was refining with peace of mind, the place where Chu Dongtian had killed the Mangniu Royal Clan before and dissected the heart core of the Mangniu Royal Clan was gradually gathered by many demon beasts. Not only are there quite a lot of these demon beasts, but there are also many types, but without exception, they all sniff hard.

Compared with humans, if a demon beast does not go to the Martial Immortal Realm, under normal circumstances, his sense of smell is much more sensitive than his sense of sight and hearing. Obviously, these demon beasts who rushed here were all attracted by the unique aura released by the heart core of the Mangniu Royal Clan after they died.

They all instinctively knew that if they got the heart core of the Mangniu Royal Clan, it would be of great benefit to them.

Of course, the realms are different, and the knowledge is also different, most of the monsters that came were only the demon beasts of the Bifu, Huahai and Chengshan realms, and there were also those in the chakra realm, and a few in the martial realm could also be seen, but there was no one in the Ning Bao realm and above the Ning Bao.

It's just because the heart core of the Mangniu Royal Clan in the Chengshan Realm no longer has much attraction to the powerhouses of such demon beasts. Unless, the deceased Bull Clan had a chakra level or higher.

Of course, Chu Dongtian didn't know about this, and even if he knew, he wouldn't have time to pay attention to it, all Chu Dongtian had to do was to seize the time to completely refine the heart core of the Barbarian Bull Royal Clan.

Otherwise, let alone being found by so many demon beasts, even if it is normal to come to one or two demon beasts of the same level, Chu Dongtian will not be able to fight against it, because if the heart core of the Mangniu royal clan is not completely refined, there will always be a residual will to impact Chu Dongtian's sea of knowledge. In that case, it would be impossible for Chu Dongtian to fight and fight wholeheartedly.

But Chu Dongtian didn't care about the situation over there, but there were other people who discovered the gathering of these demon beasts.

The people who discovered this scene were also from the Martial Academy, and they were the Lei Feng disciple Guo Runzhi, who was determined to harass and take revenge on the demon beast clan with Zhou Ziteng descending the mountain, and the Tu Feng disciple Shan Huai, who was determined to harass and take revenge on the demon beast clan and give the martial arts academy students more time to cultivate!

"Senior Brother Shan, later you are responsible for guarding the periphery, and I will take action alone to wipe out these evil beasts in one fell swoop with the power of thunder! In this way, not only can I vent my hatred a little, but I can also create an extremely strong bloody aura, attracting the attention and inspection of the stronger among the demon beasts, which may create better and more killing opportunities for Senior Ziteng and them!"

Guo Runzhi opened his mouth lightly, and his cold eyes were full of killing and contempt.

In fact, in the face of such a group of demon beasts, Guo Runzhi does have reasons and qualifications for contempt, after all, Guo Runzhi has the cultivation of the peak of fetal light, and to kill such a group of demon beasts that are only a few strongest martial arts, there is no pressure on Guo Runzhi at all.
