"What the hell is that?"

Returning to Tiandao Palace again, Fang Zheng was puzzled. The tentacle monster was not that powerful. Fang Zheng also sensed it during the battle. It was basically the type that could easily deal with the cursed children. But there were too many of them, and there was also this weird regeneration speed... No, this was not regeneration, but Fang Zheng couldn't say what it was. After all, he was sure that whether it was the Angel of Death or the Soul Primordial Flame, they definitely took the opponent's soul, and things without souls cannot regenerate...

"Owner."

While Fang Zheng was thinking hard, Nymph raised her hand and spoke.

"Um... excuse me..."

"What's wrong? Nymph, did you find anything?"

"Yes."

Hearing Fang Zheng's response, Nymph nodded, then she opened her personal terminal.

"While you were fighting just now, I investigated the monster and found that it was not a single life form as we imagined, but a collection of creatures..."

"Wait, a group? Why didn't I see that?"

Fang Zheng understood what Nymph meant. The small fish in the sea often do this. Thousands of fish gather together, just like a big fish. At first glance, from a distance, it really looks like a huge monster. This kind of thing has happened before. But Fang Zheng can be sure that the tentacles he is dealing with look like they came out of a whole.

"Because...these creatures are tiny."

"How small?"

“3 nanometers…”

“…”

Well, this Fang Zheng is really hard to tell.

"So what you mean is that I'm not dealing with a monster, but a group of monsters composed of nano-sized creatures?"

Now Fang Zheng finally understood why his Death Storm and Soul Fire were useless, and the firewood that was only the size of chocolate beans also made sense. By the way, this thing could actually cover three football fields. That number is not in the billions, it must be in the trillions!

"Doesn't this thing have a core or something?"

According to the rules of movies and games, these things usually have a core. Wouldn't it be completely solved as long as the core is destroyed?

"This... According to my investigation, this seems to be a primitive single-celled organism. It does not have a core part. They seem to resonate with the magical fluctuations of the spirit crystal and act instinctively..."

Sure enough, there is a gap between games, movies, novels and reality.

"…What should I do? How about I get a big vacuum cleaner to put them in?"

Fang Zheng was completely helpless. It was too uncomfortable to have such delicacies in front of him but not be able to eat them. Fang Zheng couldn't think of any good solution. The only useful soul stone in his hand was Masail, but it didn't work against it. As a huge group of creatures composed of countless nano-sized creatures... this was indeed a problem.

As for using a large vacuum cleaner, it was just Fang Zheng's nonsense. Although the tentacles had low defense, they could not withstand high attack speed. Even Tan Ji with a plasma shield was killed in seconds. Where could he find a container that could collect all these things?

You said that if I were to travel back in time to Journey to the West and hold a purple gold gourd, wouldn’t that be better than this? If I called that thing, it would dare to respond... That damn thing doesn’t even seem to have any vocal organs, so it really can’t respond.

Fang Zheng and Nymph studied it for a while, and finally only understood the general characteristics of this monster - first of all, this is a very primitive single-celled aquatic organism (Nymph said so), and Fang Zheng had no objection to this. After all, there are so many spiritual crystal veins, and I heard that the veins in the north have been excavated recently, and Bishop Carl or the Golden Dragon girl didn't tell him what monsters there are. On the contrary, deep-sea mining is the first time in the main world. Although I don't know if it is a special case or a common situation, it seems that this kind of thing should only live in the spiritual crystal vein area on the seabed.

Of course, to be on the safe side, Fang Zheng also used a prophecy spell to detect it, just in case this thing was a sealed demon or some other weird thing. The result of the prophecy spell feedback made Fang Zheng feel at ease. It was not a historical problem, nor was it a seal leak, nor was it a sealed demon, it was just a simple biological disaster...

Logically speaking, for biology majors, one must look for Zerg. However, after Fang Zheng called Milune over to explain the situation, the Zerg Queen shook her head desperately, saying that although the Zerg can transform and assimilate other races, but for nano-scale creatures... that would be extremely difficult, and it could even be said that the Zerg were not sure they could handle it.

Not to mention this single-celled organism.

But Nymph came up with a solution.

"Master, I have a suggestion."

"What suggestions?"

"If we can capture that creature, I might be able to analyze it. Since the basic structure and genes of single-celled organisms are the same, if conditions are sufficient, I can create a virus weapon that specifically destroys the opponent's gene chain. As long as you drop this virus weapon into the target area, you should be able to eliminate these strange creatures as quickly as possible."

Seeing Nymph saying such words with a pure and innocent face, Fang Zheng felt that his hair stood up... Creating a genetic virus to commit genocide on the target group? Little angel, why didn't I see that you are so cruel before?

"This... I'd better think about it again."

Strangely enough, if Fang Zheng were asked to burn all the monsters, he wouldn't think there was anything wrong with it. But if he were asked to spread a genetic virus specifically targeting a certain biological group to exterminate them, Fang Zheng would feel very stressed.

As expected, a career like scientist carries inherent dangers, and even artificial angels are no exception...

But as the saying goes, three heads are better than one. Fang Zheng and Nymph couldn't come up with a good idea, so they simply gathered everyone together to think of a solution together.

As expected, there is strength in numbers. After Fang Zheng finished talking about the biological community hidden under the sea, Tilia was the first to raise her hand to speak.

"Brother, then why don't we just let Hecate use the power of existence to burn all those things?"

This girl really wants to harm Hecate every chance she gets. With such a large area, I’m afraid it’s hard to say how long the fire of Hecate’s existence can last.

"It's useless. This method is only a temporary solution and not a permanent cure."

Fang Zheng shook his head and rejected Tilia's opinion. The fire of Hecate's existence was very similar to Fang Zheng's soul fire. If you catch something, you can burn it all the time. But the problem is that it is not a monster but a group of monsters. If the line is burned anywhere, it can pat its butt and slip away, and then find an opportunity to revive and start again. Considering the caves and gaps under the sea, it is not so easy to burn them all.

Kurumi doesn't have any good solution for this. She can manipulate time, but she is really helpless facing a group of nano-sized creatures. Illya's dream summoning may be able to find servants to deal with those monsters, but her servant summoning is random, and no one knows who will be summoned... This kind of luck-based thing is not suitable to be used here.

"Oh my, I have a great idea!"

At this moment, Xiao Hei raised her hand high and jumped up. Then she stretched out her hand and pointed at Yoshino who was sitting next to her.

"Big Brother, didn't you say that those monsters can only survive in water? Then why don't we just let Yoshino-nee freeze the entire area?"

"This... huh? This is really a good idea!"

After hearing Xiao Hei's suggestion, Fang Zheng nodded. After thinking about it carefully, this was indeed a solution. After all, it was impossible to kill them all, so why not just freeze them first and then extract the spirit crystal ore from them? However... considering the location and size, this is obviously not an easy task... Or maybe he could just transform himself into the Star Forging Dragon King? This seems a bit exaggerated...

"Yoshino, can you do this?"

"this……"

Facing Fang Zheng's question, Shion frowned, thought carefully for a moment, and then shook her head in distress.

"I, I don't know either... Mr. Fang Zheng, I have never tried to freeze such a large area..."

That's true. Although Yoshino's "Ice Puppet" can indeed freeze everything, this area is too large. It's three football fields, and from the sea surface to the bottom of the sea, including the spirit crystal vein, it's about 5,500 meters deep. If you calculate the volume... Fang Zheng feels like his head is about to explode.

It's no wonder that Yoshino feels dizzy. Although the power of the spirits is very strong, it also consumes spiritual energy. And whether Yoshino's spiritual power can support her to freeze such a large area of ​​the sea is really a question.

"It would be much easier if we could separate this area of ​​the spirit crystal vein..."

Looking at the map in front of him, Fang Zheng also reached out his hand to hold his head and muttered to himself. If this area can be directly isolated from other seawater with a large space barrier, then it shouldn't take too much magic power for Yoshino to freeze this area. But the problem is that Fang Zheng doesn't have much space magic in his magic. Although there are similar spells in the defense system, the effect area is not so large...

"Father."

Just as Fang Zheng was thinking about what to do next, suddenly, Musashi, who had been silent all this time, spoke.

"I might be able to fix that."
