Chapter 80: The Upper Limit of Adulthood! Life Level Evolution! (Seeking follow-up recommendation votes)
During this period of time, every night when Chu Xu closed his eyes and entered his dreams, he seemed to be able to see the huge asteroid fragments that covered the sky and the sun falling from the sky and crashing on the coast of the Yucatan Peninsula. The deafening sound of the impact seemed like the wail of the earth.

Its power was immeasurable, as if it was the legendary punishment from heaven. All living things within a diameter of 3000 kilometers were reduced to ashes in an instant, leaving no trace behind.

The falling asteroid fragments smashed through the Earth's crust and tore open the upper mantle to a depth of 10,000 meters.

Countless rocks and magma that had not yet solidified flew everywhere, carried by the violent cyclone straight into the sky, and finally turned into a rain of lava with a temperature twice that of the sun's surface, like a dance of death representing the end.

The huge tsunami that followed was 300 meters high, the super earthquake reached 12 degrees, triggered a 1000-level super hurricane with a speed of more than 56 kilometers per hour, global forest fires, and acid rain that lasted for decades.

After these horrific secondary disasters, the Earth will usher in a long nuclear winter. Large amounts of smoke and dust particles will be injected into the atmosphere, blocking sunlight from reaching the surface, causing the surface temperature to drop by dozens of degrees.

As the most important producers in the food chain, plants quickly withered, causing the global food chain to collapse. Finally, in just a few hundred thousand years, the last dinosaur dynasty of the Late Cretaceous was destroyed.

Even Hell Mode is no more than this!

However, from being frightened and caught off guard at the beginning, Chu Xu is now fearless and faces it calmly.

[Ding! The host's current four-dimensional attribute value has reached the upper limit of adulthood, and it is temporarily unable to increase points. Spend 1 million evolution points and devour enough metal substances to evolve to the next form. ]

The reason is simple. He has finally reached the upper limit of adulthood and is about to evolve into his ultimate form!

Chu Xu had been waiting for this day, and he didn’t know how long he had been waiting!
From the weak and defenseless Tyrannosaurus Rex cub at the beginning, to the emerging teenage Agumon with a certain degree of self-defense ability;

From the adolescent Tyrannosaurus who dominated one side, slayed the Wind God Pterosaur in the sky, and destroyed the Mosasaur in the sea, to the adult Machine Tyrannosaurus who roamed the world and unified the seven continents.

Next, we will finally welcome the ultimate form of the Greymon series - Battle Greymon!
After evolving into Battle Greymon, the first thing Chu Xu has to do is to prevent the asteroid fragments from hitting the earth, saving himself and his family, as well as the entire last dinosaur dynasty of the Late Cretaceous period!

——If there is no sun in this dark polar night, then I will be the only light!

……

Hell Creek Forest, North America.

After nearly a year of vigorous development, World Subtree No. 1 has grown to a height of 500 meters, and has finally grown from the bottom of the tiankeng to the outside world, showing its miracle of bringing rain to all things and benefiting all living things in front of all creatures!

The range of the digital energy it broadcast has increased by more than a hundred times, radiating to almost the entire Laramidia subcontinent, which is equivalent to half of North America.

Even the marine life of the Western Interior Seaway was included, gradually embarking on the road of evolution.

Not only has the radiation range expanded, but as time goes by, the creatures here have finally entered the final stage of life level evolution!

In the vast forest, every tree seemed to have taken drugs, soaring into the sky, with an average height of almost 100 meters, and the expansion range also included the entire northern Rocky Mountains. Dinosaurs from all over North America gathered here, and they were like devout believers, often kneeling in the direction of the world sub-tree, making deep and melodious howls.

"Roar!!"

Among the towering ancient trees, a dragon roar suddenly sounded. In the direction where the sound came from, three Tyrannosaurus Rex, one big and two small, were patrolling their territory.

The adult Tyrannosaurus Rex has a body length of 30 meters, a height of over 15 meters, and a weight of 300 tons. Its rough red scales look like volcanic lava, and it spews out wisps of high-temperature steam all the time.

The protruding, angular bone plates spread along the spine and grew into a thick tail that was half the length of the body. The mouth was full of huge banana-like teeth with thick lips, and the claws of the slender forelimbs were as sharp as guillotines. The overall image showed the ferocity of a generation of dinosaur tyrants to the fullest!

This adult Tyrannosaurus Rex is naturally the mother of dragons.

And now she can no longer be called a Tyrannosaurus Rex, she has evolved into a mature Gigantosaurus!

Gigantomon, also known as Tyrannosaurus Monon, is another evolved form of Agumon. It also controls the power of fire, and its special move is [Flame Breath] which spits out crimson high-temperature flames.

Following behind the Mother of Dragons, Crescent Moon and Liuxing, one white and one black, are 13 meters long, 7 meters tall, weigh 15 tons, and have also entered the final stage of life level evolution.

The snow-white Crescent evolved into a mature Snowstormmon, a subspecies of Greymon that lives in the snowfields. As a result, it controls the opposite power of ice and snow. Its special move is to spray out ultra-low temperature blizzard from its mouth [Super Blizzard];
The blue-black Ryusing evolved into a mature Blue Tyrannosaurus, which is also a subspecies of Tyrannosaurus. It has a more ferocious temperament and its special move is the [Super Flame] which is an ultra-high-temperature flame that it spews out from its mouth.

It's not just them. When Long Ma, Xian Yue and Liu Xing were patrolling the territory, they could see that many of the dinosaurs living there had undergone earth-shaking changes.

Among the group of ceratosaurus, a giant ceratosaurus with a body length of more than 20 meters is leading the group to forage for food.

The skin of the giant ceratopsian has been highly hardened, with a hardness comparable to that of diamond, as if it were covered with a set of heavy armor.
The three horns on the top of the head are no exception, especially the nose horn which is particularly prominent. It is almost half the length of the body, thick, long and sharp like a spear, pointing proudly to the sky, flashing a special metallic texture.

This giant ceratopsian has also evolved into a mature ceratopsian beast, and its special move is the [Single Horn Assault], which is to charge with the horn on its head.

The other ceratosaurus following this one were also quite large, with body lengths of almost 10 meters, far exceeding the ordinary adult ceratosaurus.

In addition to this group of ceratosaurus, looking around, there are also giant ankylosaurs that are equally huge, with their bone plates completely made of metal - mature ankylosaurs.

These ankylosaurs not only ate plants, but also began to dig and search for various metal ores to eat, thereby continuously turning their own bone plates into metal that is invulnerable to swords and guns, and is impervious to water and fire.

Especially the huge tail hammer at the tail has completely turned into a steel hammer, which can perform the [Giant Tail Hammer]. Combined with a body size of hundreds of tons, its lethality is many times more terrifying than that of ordinary ankylosaurs in the past!
