In the passage, colorful crystals are everywhere.

Quintasa took Sun Yu for about fifteen minutes, and finally stopped at a place similar to a gate.

"What is this?" Sun Yu asked.

Then the faint light emitted by the crystal, Sun Yu took two steps forward and touched the metal wall in front of him with his hand.

"The core of consciousness of the universe emperor should be behind this sect."

Feeling the dark black and cold metal door, Sun Yu narrowed his eyes slightly. After scanning and detecting, he was surprised to find that he could not detect the thickness of the door.

He took two steps back, returned to Quintasha and asked, "How should we pass through this gate?"

Quintasha shook her head: "It's the first time we've come..."

When he arrived at the edge of the corridor, Sun Yu reached out to touch this purple crystal that he had never seen before. Just as his fingertips were about to touch the surface of the crystal, the luminous intensity of the crystal suddenly increased. At the same time, a strong current flowed into his body along Sun Yu's fingertips.

Sun Yudun felt a numbness all over his body, and the mechanical substance nanoworms had ripples and ripples...

"There is a very strong energy in the energy crystal. What I used to absorb before was this energy. The high-temperature energy emitted from the earth core is the basic energy source of this crystal." Kuntasha explained.

Sun Yu nodded.

Just then.

Sun Yu felt the ground shaking...

And the frequency of vibration is getting bigger and bigger.

The system prompted him that an object behind him was approaching quickly.

Quintasa suddenly turned around, looked at the way she came, and said, "You touched the crystal, stimulated the autoimmune system of the universe emperor, and the guards are here."

When Sun Yu heard the words "The immune system", he narrowed his eyes slightly. This is very interesting. Humans have an immune system themselves, and robots actually have an immune system. However, although they are curious, they did not surprise him much. It is very consistent with biological common sense. It would be weird if they do not have an immune system.

The Emperor of the Universe has a very big head and the system inside is very complex. Without the protection of the immune system, it is not possible for any Transformer to destroy his body when he comes in.

In fact, any kind of creature is afraid of invisible enemies.

Just like a tiny virus that is invisible to the naked eye, it will invade the human body and destroy the human body. The invisible enemy is the most terrifying.

This reminded Sun Yu of the Demon-Eye civilization that was destroyed by the Three-Body Man.

The vibration is getting louder and louder, and the frequent metal hitting sounds are getting closer and closer.

Sun Yu was a little curious about what the immune system of the Universe Emperor looked like.

Just then.

Several large mechanical bugs with eight legs stopped not far in front of Sun Yu.

Their upper jaws began to separate from each other, and a detector-like device extended out in the middle. As a red beam shot out, these mechanical bugs began to scan Sun Yu and Kuntasha.

After the scan, the mechanical bug's eyes instantly turned from green to red. Although they didn't speak, Sun Yu could still see from the actions made by the mechanical bug, which was calling his companion.

"These are mechanical lives created by the internal immune system of the Universe Emperor, and they are responsible for cleaning up foreign invaders." Quintasha explained.

Of course, Sun Yu understood this principle. The internal mechanical assembly factory is equivalent to the leukocyte generation process inside the human body.

And these mechanical bugs are equivalent to white blood cells.

If this is the case, then after the bug sends an early warning, there will be a continuous stream of antibody bugs coming.

Sun Yu said: "We may not have much time left."

Quintasha nodded: "We must first pass through that door."

After the words came, Quintasa stopped Sun Yu: "I will deal with these bugs, you can find a way to penetrate that gate."

"Then be careful."

Sun Yu came to the dark metal door. He took off the nanoworms in his hand, revealing the metal finger bones. Then the first phalanx turned upwards, and a small laser cutting bucket suddenly appeared.

Accompanied by a dark red laser, Sun Yu tried to use a high-temperature laser to cut this metal door with an unknown thickness.

However, he was surprised to find that even though the laser temperature had increased to 20,000 degrees Celsius, the metal door was still unscathed.

And Quintasha has already fought with the immune mechanical insects.

How could this mechanical insect be the opponent of Kuntasha? Every time there is a discharge, several mechanical insects will be killed.

After a while, the corpse of the mechanical insect had completely blocked the passage.

However, the mechanical bugs behind began to transport the corpses of their companions backwards.

The internal factory that produces this mechanical bug has also begun to start urgently, and the production of mechanical immune bugs is in batches.

Quintasa retreated to Sun Yu and asked, "How is it?"

Sun Yu shook his head helplessly: "The laser cannot be cut."

"This is the last line of defense for the core of the consciousness of the universe emperor. This metal has only appeared in ancient times. It is said that the most important parts of Yuanshi Tianzun and the universe emperor are made of this ancient metal."

After pausing for a moment, Quintasa looked at Sun Yu: "Using the scepter to drain the energy of the Universe Emperor outside is the wisest choice."

Sun Yu shook his head, he definitely wouldn't use that method.

Just then.

The corpse of the mechanical insect that had just blocked the passage was transported away by the insects that followed, and a large number of mechanical insects rushed over.

Quintasha did not talk nonsense, but rushed straight towards the mechanical insect swarm.

"You'd better hurry up, my energy is limited."

Sun Yu did not speak, but nodded, and then he fell into deep thought.

Sudden.

He had a flash of inspiration and thought he had it.

Since this metal is so heat resistant and hard.

No matter how awesome you are, you are not as powerful as the power of space.

"Quntasha, come back." Sun Yu shouted.

Hearing Sun Yu's call, Kuntasha quickly came to Sun Yu's side after killing a mechanical insect.

"Shield Belt!"

Sun Yu stretched out his hand to Quintasa.

Quintasha, who was a little confused, did not ask any more questions, but unbuttoned the shield belt on her waist and handed it to Sun Yu.

Taking the shield belt, Sun Yu pressed the belt onto the metal wall. Then some of the mechanical nanoworms left Sun Yu's body and firmly fixed the belt onto the wall.

Immediately afterwards, Sun Yu opened the shield belt and adjusted the shape of the shield, wasolating all the mechanical insects that were coming to support on the other side of the passage.

"What are you going to do?" Quintasha asked.

Sun Yu did not explain anything to Quntasha, but retreated to the metal wall. He turned his body sideways, and under Quntasha's astonished gaze, Sun Yu summoned the time and space gate.

The space-time gate tears the space and spreads rapidly.

The moment the torn space touches the ancient metal, it cuts a gap in the ancient metal without any effort.

Immediately, Sun Yu closed the time and space gate.
