It takes an extremely long time to fuse the third-level gene fragments. During this period, the three dwarf tyrannosaurs will provide food for Xu Kun, and Xu Kun will no longer have to eat carrion.

As the gene fragments fused, bone plates began to grow on Xu Kun's back, and the bone spurs on the bone plates gradually appeared. Finally, twenty-one days later, gene fragment 23 was completely integrated with Xu Kun's genome.

At this time, Xu Kun was covered with hard bone plates from his neck to his tail, covered with sharp bone spurs. The defense on the back of his body was directly stretched. The only shortcoming was that there was no bone hammer growing out of his tail, but Xu Kun could

Kun is already very satisfied.

Xu Kun walked out of the cave. He could feel that due to the existence of bone plates, his body had become much heavier. At this time, his weight was close to two tons.

Outside the cave, the three dwarf tyrannosaurus and the little dromaeosaur stood up immediately after seeing Xu Kun. Then Xu Kun led the hunting team to patrol the entire valley. It felt like a bully in the valley, and the little dromaeosaur ran away.

The most joyful thing is the posture of a fox pretending to be a tiger.

When the group came to the entrance of the river valley, Xu Kun discovered a sub-adult Tyrannosaurus rex. It has to be said that Tyrannosaurus rex was a very successful species at the end of the Cretaceous. There were many of them, which should be consistent with their exclusive use of large-scale predators.

It is related to this ecological niche.

According to the information obtained from the animal's business card, this sub-adult Tyrannosaurus rex is nearly ten meters long and weighs more than five tons. Although it has not yet reached its peak, except for those mutant creatures and adults of its kind, it is already difficult to survive.

There are other predators that could threaten it.

This Tyrannosaurus rex had just killed an adult hadrosaur and was about to eat when it ran into Xu Kun and his party.

"Roar..."

The sub-adult Tyrannosaurus rex let out a deafening roar, intending to warn Xu Kun and his party to leave quickly. The small Dromaeosaurus was originally running at the front, but when he saw the formation in front of him, he quickly hid behind Xu Kun.

Although this Tyrannosaurus rex has advanced to the third level, it is still a weak third-level life form. With Xu Kun's current hard power, he cannot compete with it head-on, but with the addition of three dwarf tyrannosaurs, this is not necessarily the case. This is an acquisition.

An excellent opportunity for the Tyrannosaurus rex genome.

So in the face of the warning from this sub-adult Tyrannosaurus rex, Xu Kun did not retreat, but signaled three dwarf Tyrannosaurus to surround it. Unlike the Ankylosaurus he hunted last time, this Tyrannosaurus rex was very mobile.

It is much better, and it also has an amazing bite force that can break bones, making it a very dangerous opponent.

The sub-adult Tyrannosaurus Rex could clearly feel Xu Kun's hostility, so it lay down in a defensive posture.

Xu Kun arranged for a dwarf tyrannosaurus to roar at the sub-adult tyrannosaurus rex directly in front, distracting it and allowing the other two dwarf tyrannosaurus to turn behind it and wait for an opportunity to attack.

I saw one of the dwarf tyrannosaurs quietly attacking from behind, biting the hind legs of the sub-adult tyrannosaurus. The sub-adult tyrannosaurus felt excruciating pain, and it swung its hind legs, and the attacking dwarf tyrannosaurus was thrown away

Got out.

The sub-adult Tyrannosaurus rex turned around and pounced on the dwarf tyrannosaurus that had just attacked it. At this time, the dwarf tyrannosaurus that was directly in front of it launched another attack.

For a moment, this sub-adult Tyrannosaurus rex fell into a passive state, so it no longer thought about protecting its prey, but chose to escape.

"Chase!"

Xu Kun gave instructions to the three dwarf tyrannosaurs, and they quickly chased the escaping sub-adult tyrannosaurus. The dwarf tyrannosaurs were much faster than the adult tyrannosaurs, and soon the three dwarf tyrannosaurs chased it again.

They were surrounded.

"Roar!"

The sub-adult Tyrannosaurus rex felt threatened, raised its neck and roared, this time it was ready to fight for its life.

The three dwarf tyrannosaurs repeated their old tricks, one was still attacking the sub-adult tyrannosaurus from the front, and the other two turned behind it to sneak attack.

But this time, when a dwarf tyrannosaurus bit its leg from behind, it directly bit its back with its big mouth. At this fatal moment, Xu Kun slammed into Ya Ya with the help of the hard bone plate on his back.

Adult Tyrannosaurus rex.

"Roar..."

The sub-adult Tyrannosaurus rex let out a scream. It staggered and almost fell down. At this time, another dwarf Tyrannosaurus rushed forward and bit its neck.

The sub-adult Tyrannosaurus rex suddenly swung the dwarf Tyrannosaurus away, and then rushed towards Xu Kun. At this time, the timid little Dromaeosaurus jumped up and pounced on the Tyrannosaurus rex, but was directly ejected.

Xu Kun's body agility was greatly reduced due to his bone plate. He was unable to dodge the ferocious attack of the sub-adult Tyrannosaurus rex. The sub-adult Tyrannosaurus rex's bloody mouth firmly bit Xu Kun's back.

.

In panic, Xu Kun instinctively discharged electricity, but because the conductivity of the bone plate was not very good, the current output was affected.

Therefore, the lethality of this discharge attack to the sub-adult Tyrannosaurus rex was relatively limited. At this time, it was already red-eyed. Although it suffered an electric shock, it did not let go, but instead bit it with all its strength.

Xu Kun felt the terrifying bite force of the sub-adult Tyrannosaurus rex through the bone plates on its back, but his bone plates were hard enough. Several of the teeth of the sub-adult Tyrannosaurus rex were shattered, but Xu Kun was still not broken.

of defense.

At this time, three dwarf tyrannosaurs rushed up to bite the sub-adult tyrannosaurus rex. It let go of Xu Kun and let out a heart-rending roar. Then it suddenly swung its body and threw the three dwarf tyrannosaurs away.

At this time, Xu Kun saw the opportunity and hit the neck of the Central Asian adult Tyrannosaurus rex. The sharp bone spurs on his head directly penetrated the throat of the sub-adult Tyrannosaurus rex.

The sub-adult Tyrannosaurus rex roared like a trapped animal. It was seriously injured and would only die if it continued to fight.

So the sub-adult Tyrannosaurus rex had no choice but to continue escaping out of the river valley with staggering steps. The three dwarf Tyrannosaurus continued to chase it and soon surrounded it.

The seriously injured Tyrannosaurus rex kept turning its body. It was already quite tired and weak. At this time, Xu Kun rushed over and slammed into it.

This time, the sub-adult Tyrannosaurus rex was at the end of its strength. It could no longer hold on, and its huge body fell to the ground. Xu Kun raised his foot to step on it, and then opened his mouth to bite its throat.

The neck of the Tyrannosaurus rex was very thick. At this time, Xu Kun could deeply feel the lack of his bite force. He and the three dwarf Tyrannosaurus took turns biting for more than 20 minutes before killing the sub-adult Tyrannosaurus rex.

But just when Xu Kun was about to eat, the cry of another Tyrannosaurus rex came from the distance.

It turned out that the roar of the sub-adult Tyrannosaurus rex just now attracted its adult counterparts. Xu Kun wanted to take a bite of meat and then withdraw, but for a while he was unable to tear its thick skin. He had no choice but to give up and obtain the Tyrannosaurus rex genome.

An excellent opportunity.

So Xu Kun led three dwarf tyrannosaurs and small dromaeosaurs to retreat into the valley. In this battle, they killed a sub-adult tyrannosaurus rex. Xu Kun got a chance to edit the third-level gene fragment, but they also paid a lot of money.
