The demon's description of the fifth mass extinction is just a speculation, so he did not specifically analyze the cause of the extinction and the specific performance of the earth at the time of the extinction, maybe he wanted to deduce these details at the time, but maybe his life limit did not allow him to do these additional work, until here, the study of this is over.

However, Zhang Jun knows that the fifth mass extinction is likely to be caused by the impact of planets on the earth, which is consistent with the results deduced by the demon spirit, because after the asteroid hits the earth, it will cause a large amount of dust to fly out of the ground and cover most of the earth, resulting in these areas not seeing sunlight all year round, and the temperature is below zero for a long time, resulting in mass extinction.

The method of avoiding the fifth mass extinction pointed out by the demon spirit is very peculiar, and it is actually possible to choose to enter a place called the Time and Space Temple, this area called the Time and Space Temple, which is also named by the demon spirit itself, in fact, this place is the site of the alien spaceship crash, a cabin left by the spaceship, the cabin is very huge, according to the description of the demon spirit, its diameter is five hundred meters, it can be seen how big the diameter of the wrecked spaceship is.

A large space capsule with a diameter of 500 meters is already equivalent to the campus area of a medium-sized university, it seems that the aliens and instruments and equipment that this spacecraft can accommodate at that time must be a very staggering number, the demon spirit only saw the wreckage of the spaceship back then, and the space-time temple was also excavated by him from the soil, which is the most well-preserved part of the wrecked spaceship.

"The location of the Time and Space Temple should be in eastern China, about two to three thousand kilometers away from here?" Based on the location of the map, Zhang Jun roughly guessed the specific location of the Time and Space Temple.

According to the demon spirit, the wreckage of the wrecked spaceship is still preserved in ancient eastern China, and the area he depicted is a mountainous area, and it is also a very characteristic mountainous area, where there are very tall coniferous trees, almost all of the area is covered by coniferous wood, in the Jurassic, such a pure mountainous area is rare, plus the longitude and latitude of this area can be seen on the map, if you use the instruments left by the demon spirit, it should not be difficult to find there.

However, this is far away from the location of the Temple of Time and Space, and there must be many areas infested with fierce beasts along the way, and the safety issue is the key, whether Zhang Jun can successfully cross the journey of 3,000 miles and complete a journey similar to the journey of learning from the West in Journey to the West, is still unknown.

However, at this time, there are still seventy or eighty million years before the mass extinction, and Zhang Jun is not in a hurry to find the Time and Space Temple, and the problem he wants to solve first is to find the fourth genetic code lost by the demon spirit first, so that he can obtain a stronger genetic mutation ability.

Since the previous genetic code ability has been tested by the demon spirit, that genetic mutation has made the life of the demon spirit last for two million years, so Zhang Jun is confident that he can obtain the same ability as the demon spirit and extend his life for at least two million years.

If the facts are really as stated by the demon spirit, then Zhang Jun can continue to search for the fourth stage of the genetic code chip in the past two million years, and the only thing he can rely on now is the instruments and equipment left by the demon spirit.

According to the meteorite prompt, the demon left the detection instrument he left behind, that is, buried in an area under the meteorite, and only needs to dig five meters to find it.

Zhang Jun saw that it was already dark, so he decided to take the dragon group back to the dragon's nest first, and wait until dawn the next day, and continue to dig here, and there will definitely be something to gain tomorrow.

After returning to the dragon's nest, several small dragons were playing near the temporary dragon's nest, seeing Zhang Jun back, the bald head and a few small dragons came around, screaming towards the leader's brother, expressing affection, a male and a female two dragons are still resting on their stomachs, the male dragon's leg injury began to improve, although he could not stand up and walk, but the wound had already healed, and it was estimated that he would be able to walk in a few days.

Zhang Jun thought about moving the dragon's nest to the cave by the lake, where the environment is better, but there will be unknown sea creatures in the puddle, which will come out from time to time to disturb, and the safety of those little dragons who like to play is threatened, so he hasn't decided yet, and he thinks that maybe he can make a nest near the cave, with his back against the big rock, which is also a good choice, and there is also the evil dragon's lair, which is also a very good choice.

Early the next morning, Zhang Jun set off with the dragons, this time he took the little dragons out, arrived at the location of the sinkhole, and began to dig the ground, and several little dragons also imitated and helped a lot. It took a long time to dig five meters deep, and thanks to the clear location information of the demon spirit, he soon saw what he wanted.

When Zhang Jun was excavating, he thought of the scene he had seen many archaeologists digging ancient ruins, and he seemed to have become an archaeologist at this time, excavating the objects buried deep in the ground for millions of years, studying its historical value and significance to today's society, but at this time, no one could share his feelings, so he had to feel alone and lonely.

Soon, several items came out from under the ground, one of which was only half the size of a palm, which was the detection instrument that the demon spirit said, and he used this thing to track the location of the genetic code chip.

This instrument is a rectangular block, like a radio, thinner than a radio, the color is silver, there are several buttons that look like buttons, there is also a slender antenna on a corner that can be pulled out, and there are several instrument display panels on it, showing the symbols and patterns of the emperor Xingwen.

Zhang Jun took the instrument out of the soil, and then blew off the covering soil layer with his mouth, and when he held the detector in the palm of his hand, he found that one of the red indicators suddenly lit up, and the detector seemed to react.

According to the description of the demon spirit, Zhang Jun knew that the energy source of this detector was cosmic rays, and it could also absorb solar energy, so it was an instrument that could be used in a variety of natural environments.

From the detector, Zhang Jun did not find any useful information, the demon spirit waited for two million years, but did not find the lost genetic code chip, and he did not expect to get anything for a while.

The lifespan of two million years is already a great gift for Zhang Jun, and the next time is still very long, maybe he can get another revelation in the long historical space, so as to further survive.

Two hundred years have passed, Zhang Jun doesn't know what he will evolve into, but from the perspective of biological evolutionary history, two million years is not very long, human evolution took nearly eight million years, and the difference between the physical appearance of the ancestors millions of years ago is not too big.

There is no display on this detection instrument, it has a direction finder on it, which can point to the direction of the gene code chip, and a distance display, which can display the chip distance, these are all designed by the demon spirit before his death, and it is a detection instrument made by him!

ps: Today's classification is strongly recommended, I hope you will support more, collect, recommend!
