After a while, a tall and sturdy Allosaurus walked towards the barbecue wood, it was an Allosaurus with blood-red eyes, it looked fierce, a little terrifying, and people couldn't feel good at a glance.

Red eyes are born with red eyeballs of Allosaurus, which is probably the result of genetic mutations, it was born with a withdrawn surname, and other Allosaurus can not play together, when it grows up, it often has conflicts with big dinosaurs, and finally Zhang Jun drove it and several Allosaurus out of the dragon's nest in advance.

When Blackskin saw Red-Eye's sudden appearance in the jungle, he immediately stood up in surprise, with a hint of anger in his eyes, because he clearly remembered that Red-Eye had almost fought with himself for a piece of dragon meat, and it was a dinosaur that did not listen to discipline, and his surname was very irritable.

Heipi let out a low roar in his mouth, but he immediately turned his head to look at Zhang Jun, and found that Zhang Jun had been looking at the red eye for a long time, and there was no reaction, so he understood that the red eye was allowed by Zhang Jun to walk in, so he immediately lay down again, ignoring the red eye.

"Chief, I'm back." The red eye looked a little thin, as if it hadn't eaten for a while, and it came over and said respectfully to Zhang Jun.

Zhang Jun glanced at it a few times, saw its haggard and hungry, and then said: "Red Eye, you broke the rules, you can't do this next time, don't come back in the future." ”

Red-Eye didn't answer, then turned his eyes to the Tyrannosaurus meat that was being grilled, and his nose took a deep breath, saliva flowing from the corners of his mouth.

Seeing this, Zhang Jun immediately ordered: "Bald, get two pieces of meat for the red eye." ”

The bald man was eating meat, and it also saw Red Eyes coming over, and after listening to Zhang Jun's words, he immediately tore off two large pieces of meat with his claws and threw them out to Red Eyes: "Red Eyes, eat slowly." ”

The bald man also has a bad impression of red eyes, but his temper is much better than that of black skin, so he does not look coldly at red eyes, nor is he overly enthusiastic.

Red-Eye knew that the dragons couldn't accommodate it, but it was hungry and didn't mind this, so it immediately lay down and nibbled on it, and after a while, it ate several pieces of tyrannosaurus meat before it felt a little full.

After eating and drinking, Zhang Jun waited for Red Eye to leave on his own, but after Red Eye wiped his mouth, he walked in front of Zhang Jun, and then lowered his head and whispered: "Chief, I have no way out, my Allosaurus brothers in the south were all killed by Tyrannosaurus, and I am the only one left, they drove me out of that jungle, I want to return to the dragon's den, please ask the leader to agree." ”

Zhang Jun was a little embarrassed, and said with a slight startle: "Red eyes, you know that my rules can't be easily broken, don't talk about it anymore, leave now, it's useless to talk more." ”

Red Eyes saw the firmness in Zhang Jun's eyes, he stood in place for more than ten seconds, did not speak, and then turned around and left with a hint of grievance.

Although Zhang Jun didn't like Red Eye either, Red Eye's lonely expression just now made him feel a little pity, but he didn't want to break the rules, so he didn't call Red Eye back and let it leave alone.

The noise in the meadow was still not over, the sound was far away, and the dragons were in harmony, enjoying the pleasures of intelligent creatures in the Cretaceous period, and the days passed.

Then the dragon group began to return to normal life, and then Zhang Jun did another big project, that is, to prepare for a possible mass extinction in advance, he estimated that the time of mass extinction was not far away, so he had to take precautions.

Zhang Jun began to order Allosaurus to transform the dragon's nest and transfer the dragon's nest from the ground to the underground, this project was very large, so it lasted for several years before a more hidden underground dragon's nest was built, and Zhang Jun also made a mechanism in the cave, once the mechanism was activated, then the entrance to the underground dragon's nest would be closed by large stones, and then it would be buried by dry soil.

Zhang Jun has the dormant agent given by the Blue Scorpion Prince, so when the mass extinction comes, the dragon group is in a frozen dormant state underground, and as soon as the validity period of the elixir expires, their hearts will beat again, which is equivalent to obtaining a rebirth, and during the period of this dormant agent, the dragon group is equivalent to stopping growth, so two hundred years later, ordinary Allosaurus can also come back to life.

The Cretaceous dinosaurs were very rich, including the original existence of the dinosaurs, as well as the dinosaurs evolved from other dinosaurs, such as ornithischians, crocodile-billed dinosaurs, lizards, ornithistosaurus, raptors, crested dragons, large ducks, psittacosaurus, flat-headed dragons, giant dragons, aeosaurus, swollen-headed dragons, and thousands of other dinosaur species of various shapes and genera.

After Zhang Jun stayed in Africa, there were more than 300 species of dinosaurs of all sizes in this vicinity, among which the famous Tyrannosaurus rex, carnivorous rex, and velociraptor were all patronized, but they were all killed or driven away by Zhang Jun, and his dealings with dinosaurs also reached the highest peak in history, but he knew that these guys would become extinct soon, and when the time came, none of them would be seen.

For the next hundreds of thousands of years, Zhang Jun has been waiting for that moment to come, and he is ready, no matter what the cause of the mass extinction, there will be a process of extinction, so he doesn't have to rush into the underground dragon's den, just wait for the signs of extinction to appear before acting.

For hundreds of millions of years, Zhang Jun discovered the fact that his body has always been very healthy, and he has not had a serious illness, and the immortal six dragons are also the same as himself, maintaining this state, and other allosaurus, occasionally die because of disease, once it is found that there is an allosaurus disease, Zhang Jun has to isolate or expel it, and if necessary, he will be ruthless to kill, in order to ensure the health of the dragons, to continue in the best state, he has to harden his heart.

Zhang Jun felt that the reason why he and Liulong's bodies had always been very healthy was probably because of the genetic mutations they produced, and the genes that resisted diseases were also added, and many diseases may have been invisibly killed by the mutated genes.

Zhang Jun speculated that the upcoming fifth mass extinction should be caused by an asteroid hitting the earth, because some scientists agree with this view, and a crater with a diameter of 300 kilometers has been found in Central America.

There are several other theories, such as volcanic eruptions, viruses, air pollution, and so on, but Zhang Jun has not been able to find any serious diseases circulating among the dinosaurs so far, and there are no signs of destruction caused by diseases, and the composition of the atmosphere is not bad, and although the volcanic activity has intensified, the poisonous gas ejected by the volcano does not spread all over the world, so this theory is not reliable.

Therefore, Zhang Jun deduced that the only thing that could lead to the fifth mass extinction should be the planet hitting the earth, so he did not dare to stay in the Americas, and it was also related to the huge crater found in Central America.
