With a sweep, Li Chengzhu was shocked.

The energy contained in this immortal core is not only huge, it is simply incomparably huge, even much stronger than the top-grade Heavenly Skill Spirit Stone. The energy is huge enough to be restrained to a certain extent, and it can't be seen from the outside at all, just like the essence of wood in your hand, if you don't look inside, you can't feel its surging spiritual power.

"Yes. Li Chengzhu spat out a word, and then threw the immortal core to Yuanmu.

Yuan Mu took it and understood that what Li Chengzhu said was true, and silently threw the immortal core over again. The little thing got into the body of the thunder giant beast without waiting for Li Chengzhu's command, and then dug out the immortal core and held it out.

Li Chengzhu compared it again, only to find that these two similar-looking immortal cores were very different, not only the volume was several times different, but the aura inside was even more numerous times different.

The heart of the beast king contains the spiritual power of countless generations of beast kings, how can it be compared to a small immortal core?

"What should we do now?" Yuan Mu asked stupidly, the Changhong Rope in his hand trembled, he still wanted to try the power of the newly refined immortal weapon.

Li Chengzhu glanced at him, weighed the two immortal cores in his hand, and smiled coldly: "Sit on the mountain and watch the tiger fight!"

Not far from the two of them, the corpse of another giant beast lay on the ground, and the scars on its body showed the fierceness and ferocity of the battle.

The earth was trembling, the giant trees were swaying, the wind was tearing apart, the two thunder beasts looked at each other with red eyes, and in a slam that shook the mountain just now, one of the two horns on the head of the thunder beast had broken off, and the blood erupted like a fountain that could not be covered. Drenched its head and face, even the opponent who was quite a little away from it was stirred up with a few drops of blood, and as soon as it was stimulated by its own blood, the eyes of the Thunder Behemoth became even redder, and they wanted to drip blood.

Stepping back and bending slightly, his eyes looked at his opponent with hatred, and his nose snorted fiercely, and the fallen leaves were stirred up by the air flow from his nose, scattered and scattered, blocking between the two.

Before the fallen leaves had completely fallen, the thunder beast moved, bent back and flicked forward, its head slightly lowered, its only remaining golden horn erected, and its huge body slammed into its opponent like an arrow from the string.

"Knock knock~~~Knock knock~~~" is like a war drum beating, and like a galloping horse, the ground is even trampled down and collapsed by it.

The opponent did not show any weakness, and when he saw it rush towards him, the opponent also moved his body, and the distance between the two heavier versions of the old tank was rapidly decreasing.

"Boom~~~".

Li Chengzhu felt his body tremble, and the giant tree where he was hiding trembled, and that feeling was like someone giving the big tree a blow to the bottom of the tree with a 10,000-pound sledgehammer. Xiao Xiao's fallen leaves floated down from the top of his head, and his eyes met the Yuanmu Daxian standing at the other end of the branch, and both of them were shocked and inexplicable.

Just by virtue of the shock wave caused by the collision of the flesh, the force can be as great as a fight, and these thunder behemoths are incomprehensible.

"Whoa~~~" "Whoa~~~~" The two roars came out at the same time, and the two giant beasts that collided together did not give in, with their heads on their heads, and their horns leaning on their horns, all wanting to force their opponents to retreat.

The thunder beast with the broken horn still suffered a big loss, and it felt that one of its remaining horns had cracked in the fierce collision just now, and the blood flowing from the other horn that had already been broken finally slipped into its eyes at this moment, and the blood-red eyes were blurred. I tried to blink the big eyes of the gong, trying to get the blood out. But the opponent did not give it that chance.

As it blinked, silver light flashed between the opponent's horns, making a clanging sound, and in a short time, a bolt of lightning had formed.

There was a loud "click", and the lightning finally struck out. Facing the big head of the Thunder Behemoth House.

"Huh~~" An unwilling roar, the one-horned thunderbeast was dizzy by the blow hidden by the opponent, and couldn't control its body for a while, its head was violently lifted up, and its front body turned up.

Even if the Thunder Behemoth is a master of playing with electricity, even if they have thick skin and rough flesh, even if they are already at the end of their crossbows, but taking such a close blow is just as unbearable as they are now in a state of no spiritual power.

There was no protective aura outside the body, and the originally energetic body was also lacking with the battle of the night, this blow really hurt it, and it even felt a big hole rotten in its head, where it was cold.

Before its erect body could fall, the opponent's long, pointed golden horns had already pushed up.

For any living being, the outer side of the body facing the ground is always its most vulnerable point, such as the belly of a tiger.

The blunt golden horn of rust thrusted into the thunder beast's bulging neck with a thud of its might. The Thunder Behemoth felt that it was not enough, and pushed its opponent forward unabated, until it hit a big tree, broke the waist of the big tree, and held the opponent against it, and it stopped, but the head still sent up against its golden horns.

Blood splattered, and the blood of its former companion instantly poured it into a blood gourd.

The thunder beast grunted a few times in its throat, its huge body made its last spasms, and its front two limbs were trying to pull the opponent's body, and the back limbs were also tightly digging the ground, trying to free itself from the pain, but in the end it was unsuccessful.

The breath of life slowly disappeared, and after a long time, the victorious thunder beast took a step back violently, shook its head, and the body of its former companion broke away from its golden horn.

The wound that had been blocked was really gushing out at this moment, and the blood instantly poured red on the earth.

"Whew~~~" The overcomer looked up to the sky and shouted, enjoying the joy of victory.

Suddenly, another thunder beast rushed out from one side, and before it could react, it slammed it out of the air, breaking the tree and flying the beast sideways.

It was already exhausted and lay on the ground, its thick eyelids blinking a few times weakly, trying to see the land it was familiar with and where it had lived for decades, but its eyes were imprinted with the roar of a companion's porcelain fork stepping on the earth.

Li Chengzhu swallowed his saliva with difficulty, although he had heard of the killing of social animals without the surname of the beast in order to elect the leader, but he had not really seen it until today.

Those thunder beasts, it was because of the lack of a leader that they fell into such a field, there are enemies everywhere, beware everywhere, like the situation just now, Li Chengzhu and Yuanmu have seen several cases. Each of the winning Thunder Behemoths will be knocked into the air by their companions who suddenly burst out, and then ravaged to death.

Li Chengzhu could conclude that this situation was definitely a beast roar, but he didn't expect that this kind of thing would happen to the immortal beasts in the fairy world.

In this centralized system of social animals, if the leader dies suddenly, the organized group animals will choose a new leader through a fight. But if it's unorganized, or if it's disorganized, there's a high chance of a beast roar.

These cruel animals are not kind, for the position of the leader are all eyeing the tiger, if there is a little bloody thing at this time, then it will definitely riot, see the life and kill, until the last soldier, this is also the so-called beast roar, Li Chengzhu as a reporter has heard of this secret news. Legend has it that on the grasslands of Inner Mongolia, there is a group of wolves with more than 400 numbers in all directions, sneaking into sheepfolds and attacking herdsmen.

Suddenly, one night, the wolves howled and the camp screamed for several days and nights before they subsided, and when some bold herdsmen went to find out what was going on, they found that most of the four hundred wolves were dead, and the rest were also panting.

The herdsmen said that this was the roar of the beast, the head wolf died, and the wolves were inside, and the wolves who saw a little blood began to tear and kill aimlessly, until they finally lost their minds, and only killing was left in their eyes.

Li Chengzhu originally thought that this was just a rumor, where was there such a ridiculous thing as a beast roaring.

But the scene at this moment couldn't help but make such a judgment, and Li Chengzhu was even more determined to infer that the first thunder beast he killed was their leader. Only by losing their leader will these thunder beasts become civil strife, followed by fights, then tearing apart, and finally losing their minds.

Li Chengzhu touched his chin and smiled slightly, he originally thought that the thunder beast was just the same as the last time he encountered it, who knew that it would be many times stronger, and what he didn't expect was that it was still the leader of the thunder beast group, no wonder a roar before death could make countless thunder beasts come and snipe him and Yuanmu.

There are too many unexpected things, cause and effect, if it weren't for the death of the leader, the thunder beasts would not have fought, let alone the beast roar, and it was impossible for himself and Yuanmu to hide here and watch the show with peace of mind.

The two thunder beasts below have already divided the winners and losers, the one that had already fought a battle has no power to fight back at this moment, when Li Chengzhu and Yuan Mu first came here, these thunder beasts can still release lightning and attack each other, until the end, they have exhausted their strength, and they are completely tearing each other apart with their own bodies.

The thunder beast lying on the ground opened its eyes wide and gasped out, perhaps before it died, it would be able to regain its consciousness, but what could it be? its companion in front of it was still trapped in the thrill of killing, its head lowered, its horns topped, and a collision sent it flying again, and then let out a roar of victory.

Yuanmu was originally quite excited to watch the giant beasts below kill each other, and then go down to clean up the battlefield, until finally it was boring. The long rainbow rope in his hand had no effect at all, which made him a little depressed. And there are small things to get the loot, so naturally he doesn't need his help, and in the end it was really boring, so he dragged Li Chengzhu out to fight the autumn breeze.

Find some lone thunder beasts to practice, as soon as Changhong Suo came out, those thunder beasts who were already tired were immediately tied into zongzi, and what was waiting for them would be the endless attacks of the Nine Heavens Great Luo Ding.

Changhongsuo has the name of a four-grade immortal weapon, which can be long or short, even if it is a behemoth like a thunder beast, it can tie them up in a strong knot, and they can't move at all.
