There was no conclusive evidence of the death of the Pure World Tree in later generations, and it was finally attributed to the sudden cooling of the waste star.

However, when he really saw the Pure World Tree, Qin Xiao had a different idea.

The part of a tree that sticks out above the soil is generally a one-to-one structure in proportion to the roots.

If a tree is grown in a barren area, the root-to-crown ratio will become 2:1 or even 3:1.

If a tree lives in deserts, rocks, etc., it can even reach 5:1.

The height of the Pure World Tree is 10,000 meters, which is equal to 10 kilometers.

In the era of the Big Bang, when the earth expanded, the oceans ebbed and evaporated, and there was no rain all year round, the roots of the behemoth of the Pure World Tree probably grew in a 5:1 ratio.

The roots of the Pure World Tree, which grew in this way, were already 50 kilometers long, reaching one hundredth of the Earth's radius, and during the Big Bang era, magma could appear even on the surface, let alone underground.

Beneath the unfathomable depths, the roots of the Pure World Tree were burned by flames, turning the case into decay.

This decay is devastating for humanity.

Because the Pure World Tree has no ability to absorb smoke and radiation, the air quality is greatly reduced.

These are not going to kill humanity for the time being.

However, the Pure World Tree could not play the rain and dew, so it had no ability to drive away foreign beasts.

The entire Pure World Heavenly City was like a slaughterhouse that had been suddenly discovered, and countless strange beasts smelled the aroma of the food here.

Therefore, these strange beasts are all heading towards the Pure World Heavenly City.

Qin Xiao was naturally aware of this, so he went quickly.

Outside the Pure World Heavenly City, the monitoring tower was empty, and some of them were even cut off, not knowing what kind of beast they were attacking.

The further you go in the direction of the Pure World Heavenly City, the more you can see the corpses and shadows of the strange beasts.

These strange beasts noticed Qin Xiao and the three of them and attacked them one after another.

The purgatory knife in Qin Xiao's hand slashed, instantly killing the strange beasts that came to attack them, and blood sprayed on the spot.

The Yuan Force in the opponent's body collapsed, not only that, but there was also a unique, blood-red energy that was withdrawn and integrated into Qin Xiao's self.

Qin Xiao only felt that his physique had increased a little, and this feeling was very small, but it was not difficult to notice.

It's a blood sacrifice demon body.

The Blood Sacrifice Demon Body can absorb the energy in the blood, since mastering this martial art, Qin Xiao has not had time to participate in the battle, as for the last time he hunted the starry sky giant beast in the starry sky, it was directly roasted by the stellar storm, and naturally there was no blood.

And at this time, it was the first time that Qin Xiao sensed the power of the blood sacrifice demon body.

As long as you hunt alien beasts, you can extract infinite blood and strengthen yourself.

Of course, the Blood Sacrifice Demon Body is still a terrifying body-strengthening martial art, because these enhanced physiques will be consumed during battle, unless the enemy is killed.

Once the blood sacrifice demon body breaks out, there is no way to kill the enemy, so the one who dies will be himself.

Qin Xiao knows this truth very well.

But in any case, now this martial art is a powerful martial art with no upper limit, and Qin Xiao naturally has to cultivate it well.

So Qin Xiao fought all the way.

At this time, the closer you get, the more you can see the powerful beasts, not only that, I didn't know the distance before, I just thought that there were some small insects flying next to the Jingshi tree, and then look at it at this time, these small insects are as big as cows, all of them are mutated birds and flying insects.

"Roar!"

A dragon mighty rushed towards him, and the crimson fire dragon was extremely arrogant, spewing flames and burning the city.

"Ah!!h

"Run! Come on! ”

The inhabitants of Pure World Celestial City roared.

After experiencing the Big Bang Era, the remaining human strength is at the martial artist level, and they will explode and die in the face of the purple dangerous fire dragon is no longer a coercion, but they are still not opponents, so they can only escape.

And then, dozens of Martial Sects flew out and attacked the fire dragon.

It's just that there are a large number of fire dragons, killing one, naturally jumping out of the second, and having the ability to waste stars, making it difficult for these martial sects to resist.

A martial artist died and fell to the ground, and his communicator was still broadcasting.

[Didi, warning, warning, all non-combatants, please go to the underground shelter, all non-combatants, please go to the underground shelter.] 】

And the combatants are all human beings above the Martial Sect.

In the era of the Big Bang, the Pure World Heavenly City was known as a million martial arts sects, and all of them came out to meet the enemy.

However, in this day and age, the power of the group is too weak.

When the first orange danger beast appeared, the human soldiers began to panic.

"Orange Danger Beast, Quick, Call General!"

"Who's there? Which general is in? ”

"Have the generals all run away, and where have all the people gone?"

The soldiers of the Pure World Heavenly City panicked, the military spirit had dispersed, these people began to retreat frantically, and no one still wanted to struggle, fight.

What to protect human beings, at this time, the most important thing is to escape by yourself.

Humanity began to retreat in large numbers, and the outer walls of the Pure World Heavenly City were left unguarded.

"Boom!"

A mammoth giant elephant slammed into the city wall, and the city wall built by the earth martial sect-level ability could not withstand the continuous impact of the purple danger beast, and shattered.

The mammoth rushed into the city, rolled up the flowers and plants in the city, and ate them.

The Pure World Tree exudes the aura of repelling beasts, and when this aura does not work, or reduces the huge effect, the things that tempt the beasts will naturally emanate.

With the Pure World Tree, the entire Pure World Heavenly City is full of spirit grass and spirit fruits, which can supply human cultivation, and now, these things have naturally become food for foreign beasts.

Heaven and earth spirit treasure, there will be strange beasts to protect and fight.

At this time, this last base of human beings has also become a place for alien beasts to fight.

At this moment, a voice exploded in the sky.

"Everyone, go back to your posts, otherwise military law will deal with it!"

After this person finished speaking, he exuded a powerful aura.

Great Martial King!

The man's aura only emanated for a moment before the fleeing soldiers stopped.

"It's General Xue!"

"The top brass didn't go."

"Calm down, calm down, defend, defend the second wall."

The morale of the army has finally stabilized, and the human powerhouses have performed their duties to protect the last homeland.

At this time, Qin Xiao looked up at the person in the air and had already discovered the identity of the other party.

That's Xue Qian.

In the era of the Big Bang, Xue Qian, who became the King of Great Martial Arts.

And Qin Xiao remembered that Xue Qian in the real world, the soul power was only the Great Martial King.

Could this battle be Xue Qian's battle to the death?

Qin Xiao no longer hid, and suddenly rose from the ground.

In the sky, the roaring fire dragon felt the breath of this General Xue, and for the fire dragon, this was a provocative message.

"Roar!"

A dragon roar appeared, followed by terrifying flames spewing towards General Xue.

But in the next moment, the flame broke.

The dragon's heavy body fell downward, but its head was split in two from its body.

"Poof!"

Blood spurted into the air, splashed on Qin Xiao's body, and was absorbed by the Blood Sacrifice Demon Body.
