Among the powerhouses in the universe, those who can reach more than 10 million years of lifespan and energy accumulation are all very strong against the sky, and they are also all strong in the star field, and the Blue Scorpion Prince's father, the Blue Scorpion King, is the strongest on the giant Blue Scorpion Star, and he has not yet reached the height of the fourth transformation. Generally, on an average medium and large planet with a diameter of more than one million kilometers, it is possible to have a strong person with three transformations, and in general, it is possible to produce a strong person with four transformations, which shows that the strong person with four transformations is precious.

Although Zhang Jun only needs one transformation, he can enter the list of four transformation powerhouses, this is a galaxy-level powerhouse, and in a small place like the earth, he can already run rampant. But in fact, it is not that simple at all, he must also go through a long period of fusion in order to obtain the energy from the first transformation to the third transformation, and the length of this period is still unknown.

And according to the Blue Scorpion Prince, the cosmic rays on the earth are simply negligible compared to those on the Blue Scorpion Star, and it is almost impossible to fuse the energy of the Star Spirit Crown here, so unless you go out of the Earth, this Star Spirit Crown is almost like a dead thing, useless.

But without Zhang Jun of the spaceship, it is not easy to get out of the earth, and the only way now is to extend life to the era of the emergence of a higher technological civilization, and then find a way to completely integrate the energy of the Star Spirit Crown, otherwise he will stay here until he dies, and this Star Spirit Crown is still a useless thing.

Thinking about it, Zhang Jun felt that there was only one way, that is, to find the fourth cryptographic chip as soon as possible, so that he could survive the barbarian era and enter the world of scientific and technological civilization after the emergence of intelligent creatures on the earth.

Zhang Jun, who originally thought that the Star Spirit Crown could help him continue his life, pinned his hopes on the fourth cipher chip left by the Demon Spirit at this time, and this time he was not hopeless, because the owner of the Demon Flash Star Spirit Crown has an ability, that is, he can breathe oxygen in water with his skin, of course, this ability needs to be fused for a period of time to obtain.

The Blue Scorpion Prince has already done it in his mother's womb, and ordinary Blue Scorpion people must evolve for more than a thousand years to obtain such an ability, and it only takes a year to fuse this ability directly through the Star Spirit Crown, but this is a year on the Blue Scorpion Star, and on the Earth where cosmic rays are weak, this time becomes a million years.

In other words, Zhang Jun must wait for a million years before he can complete the fusion of this hydrophilic ability, which is also an incomparably long time, but fortunately, he still has three million years to live, and he doesn't care about this time.

Then Yuzi began to live a more dull life, and the long road of evolution began, and Zhang Jun began a wild life year after year, and became more familiar with everything here.

Time flies, spring goes to winter, a hundred years have passed in a flash, Zhang Jun still stays in this cave group, and continues the race forward, and the group of Allosaurus who followed him to the east, west, north and south, and made great contributions have long since grown old, and now they are their descendants by his side, of course, there are six companions such as Bald and Qili.

Whenever the dragon group is too prosperous, Zhang Jun will drive out a group of adult Allosaurus and let them live their own lives, while he will take about a hundred Allosaurus to continue to breed here, of course, he left behind the strongest Allosaurus to ensure that the dragon group is strong enough.

Zhang Jun now meditates for a short period of time every day as a cultivator, in order to use meditation methods to fuse the Star Spirit Crown, and he also needs to often go to the water to soak for a period of time to exercise the skin's hydrophilic surname. Due to the very weak cosmic rays on Earth, the speed of his fusion was unusually slow, and almost no effect could be seen, but he still persevered.

This kind of fusion meditation is a little different from the meditation of cultivation, it does not require too strong comprehension ability, but only needs to feel the cosmic rays in the void step by step, absorb them into the body, act on the star spirit crown and your own body, and then combine it with practical exercises, so that the energy of the star spirit crown slowly merges with the body, and you can use this part of the energy.

And Zhang Jun can only further evolve through meditation and exercise, or other auxiliary means after completely integrating the energy of the three transformations, so on the earth where the cosmic rays are weak, everything he does is just laying a little insignificant foundation, and the future evolution process must be carried out in the star field where the cosmic rays are strong.

"Anyway, brother has time, take your time." Zhang Jun can only comfort himself, he has no other choice but to wait patiently, unless an alien suddenly descends on Earth and takes him to other star fields.

And Zhang Jun has already met the demon spirit and the blue scorpion prince on the earth, this is an extraordinary adventure, if there is another adventure, it will be too rebellious, so he doesn't expect any more awesome characters to help him, and feels that everything must rely on himself.

Zhang Jun now has to do one thing every once in a while, that is, to take six immortal companions such as Bald and Qili to swim in the lake with him, and his purpose is to let them evolve strong diving abilities in the future, so that one day in the future, he can take them to the ocean and swim with him.

Zhang's efforts were not in vain, as after a few hundred years, he found that he and his six companions had improved their diving ability, which initially limited them to one minute in the water, and gradually expanded to two minutes.

As time passed, this ability slowly expanded to three minutes, until they could stay underwater for more than thirty minutes, but at this time, hundreds of thousands of years had passed, and it would take hundreds of thousands of years for Zhang Jun to completely rely on fusion to evolve the hydrophilic ability, at that time he could stay in the water indefinitely, and now he can only rely on his constantly improving diving ability to wander in the water.

Hundreds of thousands of years have passed, the creatures here have changed generation after generation, and the form of the dinosaurs has also undergone some small changes, but for evolution, hundreds of thousands of years are actually not too long, some of the surrounding creatures have almost not changed at all, the form of the cycad tree is still the same, and there is no change in the slightest, except for the slightly lighter leaf color, there is not much change.

The changes of animals are also mostly in the skin color, body skin and hair color, length of small changes, most of the animals' body shape changes little, only a few animals have obvious changes in body shape, such as the body size of the virtual bone dragon in the past hundreds of thousands of times to 1.5 times, is the largest change Zhang Jun has ever seen of the animal, which may be related to their abundance of food, the least changed species of cockroaches, because they are always so big.

The temperature in this world has also dropped slightly, but the decline is not large, about the annual average temperature has dropped by about 0.5 degrees, and the feeling is not very obvious, except for Zhang Jun, no other animal can feel this slight change sensitively.
