The star beast fell heavily from mid-air, and huge waves rose on the sea. Yamamiya Ha Ren hovered in the sky, watching the star beast sinking into the sea, feeling anxious. He did not expect that even Wei San's Sumi sword could not pierce it.

What kind of terrifying existence is the super 3S-level star beast?

Now it is not a question of whether they can defeat it or not, but that they cannot cause any damage to this star beast.

Yamamiya Ha Ren swooped down and asked Ying Xingjue: "What should we do now? Wei San..."

"She will be fine." Ying Xingjue interrupted him. He was already swaying and about to fall, but at this moment, the waves were surging and the sea was heaving, and the Yamamiya brothers and sisters did not notice his abnormality.

Perception covered the star beast under the sea. Ying Xingjue forced his way past the limit of perception and finally had a hint of being able to control it.

A huge murderous intent was transmitted to Ying Xingjue through perception, almost drowning and paralyzing all his thoughts. Inside the mecha cabin, Ying Xingjue placed one hand on the light screen, with perception continuously transmitted, and the other hand put on the 'necklace' to regain consciousness from the sea of ​​killing.

The star beast suddenly made a sharp and thin cry like a child, and its huge mouth slowly opened a little, and then closed again as if resisting something.

"Its mouth opened a little!" The star beast did not sink completely, and Shan Gong Bo Ren rose into the air to observe, and immediately shouted to Ying Xingjue below.

"Cough, cough, cough." In the mecha cabin, Ying Xingjue suppressed a few coughs, wiped the blood from his lips, and continued to control his perception, but he could no longer see the situation in front of him clearly, and could only rely on his perception instinct.

The big waves on the sea surface have calmed down, leaving only the dark surges under the sea surface caused by the constant rolling of this star beast.

Yamamiya Yunan has been floating near the star beast. She didn't even dare to attack rashly. Wei San was inside, and she was worried that angering the star beast would cause greater damage.

As time passed, the star beast suddenly opened its mouth wide and made a sharper cry than before. Its spirit was resisting Ying Xingjue's perception, but it failed, and it could only open its mouth obediently while wailing and screaming.

"Wei San!" Shan Gong Yong Nan took advantage of the situation to get closer, looked at the star beast's open mouth, and shouted into it.

No one answered.

Shan Gong Yong Nan turned his head to look at Ying Xing Jue who was obviously holding on, gritted his teeth and was about to rush in, but saw Wu Chang jumped out of the star beast's mouth.

"Wei San?" Shan Gong Yong Nan shouted a little hesitantly. Wu Chang looked so fierce that even his shell had become tattered, with pieces missing here and there.

"I'm out." Wei San didn't have time to pay attention to Shan Gong Yong Nan, and went straight to Ying Xing Jue. She was more sensitive to his perception than the other two.

She approached Ying Xingjue and pressed his hand: "I'm out, retract your perception, let's go."

Ying Xingjue's consciousness was not very clear, but as long as he retracted his perception, he would inevitably be counterattacked wildly by this star beast.

Wei San controlled Wu Chang, half holding the golden armor, and took Ying Xingjue away.

"Yongnan, let's go!" Shan Gong Wave Blade swept across the sea fiercely. Shan Gong Yongnan, who was called, immediately stretched out a hand upwards. He held it and took her into the air.

The four of them had no way to release the star ship. They could only rely on the mecha to stay away from the sea. They did not find a piece of land until they were out of the habitat of this star beast and went ashore.

At this time, Ying Xingjue finally retracted his perception, but he also fell into a coma.

Fortunately, the star beast did not catch up again.

The Shan Gong siblings were not injured, but they were so shocked that they didn't know what to say when they saw one unconscious and the other in a broken mecha.

Wei San came out of the mecha cabin and brought Ying Xing Jue out. He paused when he saw the blood on his lips, then raised his hand to help him wipe it clean. He then fed him a bottle of nutrient solution and let him rest on the golden armor.

"I'll fix my mecha first." After Wei San said this, he turned around to fix Wu Chang.

"Is it corroded?" Shan Gong Bo Ren stood behind her, looking at the damaged marks on Wu Chang's shell, and asked.

Wei San nodded.

Among the five major military academies, Wei San's mecha shell is of the best quality. Many times, other people's mechas have been damaged, but hers is still intact. However, now it has become like this.

Did it enter the stomach?

Yamamiya Ha Ren took a breath in his heart, and he couldn't find a way to deal with this star beast.

Wei San put on gloves and used tools to scrape the mucus on the back of the mecha shell bit by bit. Several tool knives were corroded. If she continued to use them, she would have no tools.

"..."

Wei San stood up and looked at the optical computer. The jammer used in the previous competition was turned off, and there was a signal here.

She called Ying Chenghe, and the other party quickly picked up.

"Wei San?" Ying Chenghe was still in the studio. He didn't expect Wei San to call him. According to the time, she had already entered the Xita arena.

"Help me look at something." Wei San asked Wu Chang after he was born.

Ying Chenghe saw the broken Wu Chang and didn't recognize it for a while: "Whose mecha is this?"

Wei San: "...Mine."

Ying Chenghe was silent for a long time, staring at Wei San for a long time, and made sure that she was not injured, then asked: "What do you want me to see?"

Wei San picked up a flat stone from the side: "Look carefully."

The stone scraped the damaged part of the back of the mecha to remove the mucus on it. Not long after, the stone melted away like water.

To be precise, it was corroded, but there were no bubbles or sizzling sounds produced by normal corrosion.

"Are there similar corrosive materials?" Wei San asked.

Ying Chenghe frowned and looked at the half-remaining stone in Wei San's hand: "Where did this slime come from? Is your mecha corroded too?"

"The slime from the mouth of that star beast." Wei San threw away the stone in his hand, "I just tried it, and almost all the materials in my hand will be corroded."

This is the first time she has seen such a strong corrosive slime. Ying Chenghe knows more about this kind of star beast material than she does, so Wei San wants to ask him.

"Can this star beast spray this kind of slime?" Ying Chenghe asked.

Wei San shook his head: "No, only the inner wall of the mouth has this kind of mucus."

Ying Chenghe held a pair of pliers in his hand, picked them up and put them down, put them down and picked them up again, and finally asked: "So why did you get the mucus from the inner wall of its mouth?"

Wei San: "The outer skin of this star beast is too hard, and I think the inner wall of its mouth seems to be a little weak, so I went in."

"...Looks like you failed." Ying Chenghe threw the tool pliers on the table with a "bang", feeling his heart pounding up and down.

"Its inner wall is also hard, there is no crack, and the Sumi sword can't pierce it." Wei San reached out and grabbed a handful of hair, "My knife was lost in the mucus."

When she said this, not only did Ying Chenghe on the other end of the communication fall silent, but Yamamiya Ha Ren and Yamamiya Yunan beside her also looked over.

What do you mean the knife is gone?

"Otherwise, let's just go back." Yamamiya Yunan looked up at the sky, feeling that if they stayed any longer, they would only become food for this star beast.

Ying Chenghe flipped through the information, turned to Wei San and said, "Its mucus can destroy your sword and mecha. Even the most powerful corrosive materials can't do that."

Wei San: "This star beast's oral wall and skin are strong enough to wrap the mucus and not be harmed by the mucus."

"But it's still unreasonable." Ying Chenghe felt that this mucus was too strong. Natural balance, even star beasts are in a balance. Even if they take a step back, can star beasts evolve and use this kind of supernatural ability, instead of hiding it in their mouths just to swallow prey?

Ying Chenghe was far away on Shadu Star and could only see with his eyes. He asked Wei San to observe the taste, color, density, and corrosion rate of the mucus carefully again.

Wei San did as she was told. She had used up all the materials she had, but none of them could resist the corrosion of the slime.

The slime was gray in color. At first, Wei San thought it was the gray substance in the extreme cold arena, but after careful observation, she found that it was just slime and had nothing to do with the black insect mist.

"Different materials do have different corrosion rates." Ying Chenghe wrote down the time Wei San said, frowned as he looked at all the data, "Wei San, it's a bit strange."

"What's strange?"

Ying Chenghe stared at the data he had just written down: "These corrosion rate data are a bit familiar... wait a moment."

He turned around to look for the information, flipped through it for a long time, and finally stood up: "Found it."

"Wei San, this slime is not natural." Ying Chenghe sent her what he had found, "Fantasy beast slime, alien vine slime... The speed at which this slime corrodes materials is exactly the same as the corrosion speeds of these materials."

Generally speaking, no matter what material the slime is made of, there will be objects that corrode quickly or slowly, and the mecha master will record it after the experiment. At first glance, the mucus that Wei San was stained with could corrode everything. However, after testing it separately, it was found that the speed of corroding certain specific things was the same as that of these famous mucus materials.

"When multiple colors are mixed together, it is easy to turn gray in the end." Ying Chenghe stared at the mucus on Wuchang and said, "If you want to know completely, you have to take it to the laboratory for inspection."

Artificial...

Wei San was in the mouth of the star beast at that time. Because the Sumi knife failed, it slid down from its cavity wall and rolled inside, and then it was stained with this gray mucus. Wuchang's outer shell began to be corroded at a speed visible to the naked eye. She quickly turned to a place without mucus and scraped the mucus off her body with a knife.

In the end, the mucus was mostly removed, and the Sumi knife was destroyed. When she came out, in order to gain leverage, she even left the handle of the knife inside.

"I need to go in and take a look again." Wei San said.

"Wei San, you can't go in now!" Ying Chenghe immediately said nervously, "This kind of artificial mucus can't even stop the impermanence. You will only get hurt if you go in again."

It's okay to get hurt, but it's very likely that you won't be able to get out.

"Don't worry, I won't go now. At least wait for him to wake up first." Wei San smiled and turned his head to look at Ying Xingjue.

"My cousin is injured?!" Ying Chenghe's heart, which had just been relieved, was lifted up again.

"My perception was overdrawn. He controlled the super 3s-level star beast, so I could get out from inside." Wei San explained.

Ying Chenghe frowned, "Why do we have to deal with this star beast?"

"Without super 3S-level materials to make mechas, we can only exert 3S-level strength." Wei San looked at Ying Chenghe and said, "We need this star beast."

Ying Chenghe couldn't persuade him, so he could only say, "Be careful."

...

The three of them waited until Ying Xingjue woke up, and Wei San told him Ying Chenghe's speculation.

"Artificial mucus?" Ying Xingjue was helped to stand up by Wei San, and his temples were still filled with tight pressure. He couldn't help but say, "Let's go out first."
