4.6 Billion Year Symphony of Evolution

'boom--!'

An explosive roar, accompanied by the huge rise of the sand waves, countless monsters like twisted flesh appeared in the sand and dust, they issued a weird scream, rushed towards the towering wall.

"Attack ... is it coming again?"

Here is the highest point of the city. Many criss-cross pipes cover the whole city, and one pipe is higher than any other pipe.

To say why ... because it has been extending upward in a spiral shape to the highest point of the spiral pipe, it becomes a disc-shaped building.

On top of this building, the mechanical brain is standing there, looking down on the edge of the city in the distance with the highest perspective.

Outside the city wall, the tomb glue attacked again. This attack seemed to be more violent than before. Not only a large number of troops appeared, but also the sand waves like the sea waves constantly hit the city wall.

As before, the city wall did not immediately counter these attackers, perhaps waiting for them to gather enough to attack.

At this highest point, Nao Ling has been watching this attack. It seems to be thinking about something, and has not made any action, just observe here.

Lin has been wondering since the beginning whether this brain spirit is the ruler of the city. It seems to be able to command many things, and it still stays at the highest point of the city.

However, Lin thought ... it was not the ruler.

Mainly because Lynn found some information about the city at the Institute in Midgartne.

What can appear here is what was once destroyed by Midgart. This city is no exception. It used to be ... a very special civilization.

This civilization, just like this city, is made up of many creatures that have been transformed into 'tank machines'.

Most of these creatures come from different races. They serve as ordinary people, soldiers and other positions in the entire civilization, and have a unified feature. They all have a mechanical body and their brains are placed in jars.

Although these tank-brain machines hold various positions and various types, none of them is the real ruler of this civilization, and it is said that ... none of them knows what exactly the real ruler of this civilization is.

Later, the civilization didn't know what was the reason for attacking Midgart, causing all destruction. Only a small part, that is, the city was thrown into the cemetery.

They still maintain their usual forms of life, but the inhabitants of the tank inside have been replaced by races in Midgart, and they have not been able to develop. They have always maintained the size of a city.

There is only so much Lin knows about the city, so Lin thinks ... this city should not be ruled by residents.

Although saying so, Nao Ling seems to have many rights, because Lin sees that it is now starting to direct the cannon attack on the city wall. It uses a mechanical arm to touch the ground next to it, and a lot of three-dimensional images appear beside it. .

Then it started to poke these pictures, and only some blocks with different colors were displayed in the picture, but every time it pokes these blocks, the weapons on the wall in the distance would start shooting.

The cannon attacks on the city walls are the same as before. They shoot high-temperature substances at large tombs to deal with them.

Tomb glue has absolutely no defense against such weapons. They can only be destroyed in high temperature, but they continue to attack.

I don't know why. Tomb glue seems to want to deal with Lin's appearance. Lin thinks it may be ...

Suddenly, the brain spirit stopped the operation, and it ran quickly on the ground.

To be precise, the wheels beneath it rolled quickly, it reached the edge of the building, and stopped its body when it almost fell.

'Boom!'The next second, there was a loud noise at the place where the original spirit was, and a huge object fell from the sky and fell on the building.

This group of objects ... is tomb glue.

It looks like a big piece of meat with a length and width of more than three meters and a height of more than one meter. The piece of meat slowly crawls on the ground and also makes a voice: "I call you ... Kill it ... why not act ... kill it! "

It creaked like a low roar while crawling toward the direction of the brain.

"I don't want to do this." Nao Ling responded calmly.

"Why didn't you kill it ... why ..." The flesh was crawling faster and faster, and when it was about to touch the brain, the brain moved.

"Because ... It's easier to kill you." The moment Nao Ling finished speaking, it protruded from one side ... the third mechanical arm.

The end of this robotic arm is a cylindrical shape, and the brain spirit uses it to aim at the meat in front ...

'Hoo——' A flickering firelight shot out from the cylinder, instantly submerged the meat piece, and the meat piece continued to wriggle in the flame, but its movement became slower and slower, and finally stopped completely Down.

This brain spirit seems to ... decided to use these tombs as enemies without removing Lin's cells?

Did it recognize Lynn?This brain is really a weird character, Lin feels that she should almost grab it and study it carefully.

But I still don't do it now, because Lin wants to observe it for a while and see how this brain spirit deals with tomb glue.

It is not easy to use tomb glue as an enemy. The piece of tomb glue just like a piece of meat just fell from the sky. The source of the tomb is the sky ... the clouds.

If you look into the sky, you can see that many pale pink clouds are floating in the sky.

This is quite a weird sight, because the tomb of Midgart originally had no clouds, so this view attracted many residents.

When they looked at the sky and exclaimed, these clouds began to wriggle.

Then, the soft objects one by one, like raindrops, fell from the sky, they fell on the pipes, fell on the streets, and then transformed into ... soldiers of tomb glue.

Unexpectedly, tomb glue also has this type of attack, and the city does not seem to have a defense system corresponding to this attack.

After a while, a lot of ... screaming sounded.

The tomb glue that fell on the ground began to attack all the mechanical residents around. These residents seemed to be completely ignorant of fighting, and all screamed and ran away.

Nao Ling looked at the situation below at this height, and it didn't do anything, as if he was thinking about something.

However, the city seems to have begun ... to fight back.
