Steel steam and flame

Cassia believes that this is a rare material. Although it contains its own pollution, with the invisible fragment of the ancient historical world tree, the nature of the pollution has been changed. It is different from common pollution and will not be easily contaminated by fungi. The body is ignited; one's own blood is copied, which also makes some methods unusable. This is not bad news for him, because most of the enemies he will face in the future can find a way to deal with his blood, or have the ability to resist for a period of time.

So it was exactly what he expected. It was the material he wanted, rather than a low-quality experimental material that could be cut open and a ball of blood thrown out to wait for the results.

Don't rely too much on one ability or one advantage. Such thoughts must not occur in the world of surgeons, as death often accompanies it.

"It is an extremely dangerous type in terms of senses. You must ensure your own safety while experimenting." After noticing the line of sight that seemed to be projected on the mental body, the danger signal made Cassia's vigilance continue to grow. The next moment, mud-like pollution spurted out from the molten material below this giant polluted dragon. It boiled like lava, and a large amount of dark mist rose up, gathering toward it like a ribbon.

In the blink of an eye, the giant polluted dragon spread its wings, and a fine spider web made of polluted mist seemed to center it. The gray-white lines on its body lit up, and the next moment it opened its huge mouth, and the second gray-white light beam-like breath hit the "floating" position of Cassia's spiritual body.

"The three reasons of ancient historical world tree fragments, polluted species and underground creatures enable its perception to spread with the help of pollution? It is far more sensitive than the creatures seen before and can detect itself with the help of the root network."

Cassia, who left one step ahead, returned directly without stopping. There was a huge explosion behind him without any surprise, and another lava lake with a glass-like base was formed, bringing little light to the dark cavity of the underground world.

Although it requires testing, Cassia knows that there is still a gap between herself and this powerful creature in terms of biological strength. Without using several more special methods, looking at it from a distance is your current position.

The simulation super analysis machine has already freed up most of its computing power and is dedicated to the analysis of this polluting creature. In the process of establishing the corresponding model, Cassia first theoretically verified which methods could kill it, so as to serve as insurance if the situation was not under control.

"Let's use the uranium gold breath activated by the world core as the last insurance measure." He first considered, "Then there will be an experimental version of the terrestrial red star mode, using the world core as a pocket version of the red star, and then using the giant whale to freeze The attack method of energy lens concentration should be enough to kill it, but this needs to be done as a final test."

"In terms of strength and speed, it is not a good experimental subject, so it will not be considered this time. However, it can be repeatedly verified for the mobilization, transformation and absorption of energy by the core of the world. Developed by Li Suman herself You should be able to use the 'Annihilation' ability, so you can give it a try."

"The other is the fuel experiment on astrophages. This requires close contact before there is an opportunity to treat this polluting organism as fuel. It is very dangerous, but it is worth the risk. If you find it without contact, and It is a method that can use the target as fuel within a certain range, and then turn the core of the world into a real pocket version of Red Star, and the performance may be greatly increased. "

"However, astrophages must not be released for use. It is a huge danger to this underground world. There are exposed roots of the World Tree everywhere. Once contaminated, just putting out the fire will be a headache. Moreover, Most surgeons do not have the ability and means to "put out fires."

",,,"

While thinking about various possibilities, Cassia returned to her body.

A few minutes later, Collyux and Slova saw Cassia move when he became quiet, and then opened their eyes.

"It shouldn't be good news." Collyux said pessimistically.

"Indeed not." Cassia expressed regret.

"Then this underground creature is No. 9." Collyux continued, "The ninth underground creature that needs emergency response is not something we can deal with." As he said that, he already pointed out the direction, " The eight underground creatures were handled by extreme field surgeons. As far as we know, Master Kress helped deal with two of them, cooperating with other extreme field surgeons to handle the remaining six. It is said that it was solved by one person and it didn’t take much time.”

"That's Miss Lisuman. Such polluted creatures will not be a problem at all. After all, she was trained by the giant whale in the tundra." Cassia immediately had the answer in her heart, but did not say it out loud. He stood up and while running toward the defensive position with Collyux and the others, he briefly explained what he had observed.

But at this moment, a stream of light suddenly passed through the air beside them, leaving only a bright trajectory line, and went to the front in the blink of an eye. After more than ten seconds, the explosion and shock wave in the air came, surging everywhere.

Slova looked over and reminded in a serious tone: "The main gun of the battleship-class airship has been fired, and it is indeed a response. We hope that when the No. 9 creature catches up, we will have already joined the corresponding team. However, According to Mr. Cassia’s observation information, there is still more than half an hour, and we will contact No. 9 first.”

Cassia waved his hands helplessly, indicating that this was an established fact and could not be changed. "It is indeed extremely fast. A giant dragon-like contaminated creature with a body length of nearly 300 meters can actively absorb pollution as an energy source. It is indeed terrible."

In response, Kolyuks and Slova showed a thoughtful look, but Cassia immediately followed up: "But it is not impossible to deal with it."

"..." Seeing Kolyuks and Slova looking over, Cassia smiled dryly without saying a word, "It just delays the time a little. I can't kill this... this No. 9 creature now. I will also feel pressure when facing the contaminated creature of the extreme field operator."

"Mr. Cassia, we will not think about it, and there is an absolute risk of life, not just pressure." The two sighed and protested weakly, "But since it is you, based on the information we know, it seems that it is not impossible to understand."

"In short, this is how the Imperial Parliament describes your propaganda." The two of them felt a little complicated.

At the same time, on the other side, Klaus, holding two ultimate metal swords, jumped off the tall building and ran quickly towards the big crack on the ground.
