It has to be said that this black regiment is worthy of national-level weapons. Besieged by elite troops with well-prepared troops, with outstanding commanders in the troops, and successful trap attacks... The black regiment, which suffered a series of heavy blows, was still in equal measure with the remaining troops, and even the battle situation gradually developed in a bad direction. As the black regiment's body became smaller and smaller, its tentacles became stronger and stronger. The weapons in the hands of the soldiers of the assault regiment gradually could not cut off the armor's defense, but the tentacles could break the defense of the armor in a few strokes, killing and dragging the soldiers away. The alchemy of the Technique Guide regiment also became less and less effective, as if the black regiment had evolved resistance. As casualties continued to increase, Kosmi was forced to send the reserves of the two battalions and sent reinforcements to the command headquarters.

"Your Majesty, I have found a way to deal with this weapon." Xi, who had been speaking for a long time, suddenly said to Li Xiang.

"What's the solution?" Li Xiang couldn't help but feel happy and asked.

"Your Majesty, the Free Army is secretly supported by the Polish government. Polish weapons mainly come from dungeons. They have a good relationship with the dwarves. It is impossible to offend the dwarves so easily. Even if the Free Army dares to turn against the dwarves, the Polish government will never allow them to do that. Activating ancient weapons requires many very senior historic alchemists to work together to succeed. There is no such talent in the Free Army alone. It must be people sent by the Polish government. In order to prevent accidents, those alchemists must have tampered with weapons, leaving the weapons with fatal weaknesses to ensure that they cannot get out of here. The real purpose of the Free Army casting this weapon is mainly to try to eliminate the invaders, destroy this underground base, and cover up the evidence of crime in the base."

Xi's analysis is reasonable, which forced Li Xiang to believe that this is not German territory, and unless the leader of the Free Army goes crazy, there is no reason to destroy the city.

"Then what is the fatal weakness of this weapon? Have you analyzed it?"

Although the other party's purpose is roughly known, Li Xiang does not want the Free Army to succeed. There is a lot of evidence that is unfavorable to Poland in this base. Once it is made public, the Polish government will have great trouble. This is very beneficial to this negotiation, and he will be able to gain greater benefits.

"Your Majesty, by analyzing the internal information of the Free Army, I found a useful information, that is, not long after the weapon was activated, the Free Army spent a lot of manpower and material resources. On the basis of the already complete air purification system, it specially set up a large air purification alchemy array on each floor."

After Xi said this, Li Xiang felt that the air here was very fresh, and even the smell emitted by the ghouls disappeared quickly.

"You mean, this meat ball can only survive in pure air?"

"The possibility is as high as more than 67%. As an industrial city, Coranto City is underground, and environmental problems are very prominent. This is what everyone knows. I think the Free Army takes advantage of this and deliberately improves the requirements for air quality of meat balls. Once the environment changes, it will be difficult for organisms to adapt to the new bad environment as soon as possible, and will automatically die out. So I suggest that all air purification alchemy arrays in this base are temporarily closed and a large amount of waste gas is introduced."

The method suggested by Xi was not difficult to implement. With a try, Li Xiang told Asuna this suggestion to him. Asuna thought he had thought it out and couldn't help but look at him with even more admiration.

Then Asuna conveyed the suggestion to Kosmi. Kosmi was worried about the situation of the war. After hearing Asuna's words, he sent three companies to find the air purification alchemy array everywhere, turned it off, and at the same time told the Chief of the City Defense that he would send people to the vents to fill the exhaust gas, the more the better. Destroying national-level weapons is of great significance. Anyone with a glimmer of hope of elimination must try, otherwise, they would be filled with their lives.

Lituo Manchester, the chief of the city defense of Coranto, attached great importance to the suggestions and quickly organized people to do what she said. Soon, the waste was transported to such a layer. Two companies of alchemists launched alchemy, igniting and burning the waste, producing a large amount of waste gas. In addition, some of the alchemists launched alchemy to drive the air flow and blow the waste gas to the black ball.

The exhaust gas quickly spread throughout the battlefield. Li Xiang couldn't help but cheer up and watched the tentacles react after entering the exhaust gas mass. At first, the flesh mass did not react, which made Li Xiang think Xi's analysis was wrong, but after a while, the black mass's reaction cheered everyone up. It quickly contracted its body and retreated from the exhaust gas mass. Some of the tentacles fell off to the ground, shrinking rapidly, and finally turned into dead branches.

"Returned, retreated!"

"That's great, it's really useful!"

"It's done! That monster is indeed not used to the exhaust gas."

...

Seeing that the exhaust gas was really useful, the huge crisis was found to be a solution, from Kosmi to ordinary soldiers, and Asuna even hugged Li Xiang and thanked him excitedly.

"It's not the time to rest assured. The most powerful part of the ancient weapon is its rapid evolution. We must destroy this ancient weapon as soon as possible to avoid adapting to waste gas and evolving to a new stage. Then it will be troublesome." Li Xiang said loudly to everyone after receiving Xi's reminder.

"His Highness Raymond is right. We cannot passively wait for this monster to die. We must take the initiative to destroy it to avoid any trouble." Kosmi agreed with Li Xiang's words. He issued an order to let all the alchemists of the Technique Group launch alchemy together to speed up the generation of waste gas, and at the same time let people transport more waste down there.

The black ball was forced back by exhaust gas, and large tracts of tentacles fell off the body and died, and the body gradually shrank, from the maximum to the ceiling to the ceiling, until the diameter was only nearly meter left.

But soon after, Li Xiang noticed an unusual place through the detector, that is, dense small bumps began to grow on many tentacles on the black ball. After these bumps were broken, brown pus would flow out, and the tentacles that had this bump did not fall off again.

"No, it grows because of the stimulation, kill it!"

When Li Xiang discovered this, he immediately notified everyone.

There are many examples of organisms growing rapidly due to strong stimulation. If the black group is really fully adapted to the exhaust gas, it will still cause great damage based on its current body size.

"Everyone takes action together and gets wiped out in the shortest time."

Asuna now trusted Li Xiang very much. After hearing what he said, she immediately pulled out the thin sword from her waist and rushed out first. Her sword passed by a silver flash, constantly passing through the tentacles beside her. Every attack it emitted was cut off, which was incredibly fast.

Yasna has a very high prestige. As soon as she took action, the people from the Blood Alliance Knights or other mercenary groups followed her and launched alchemy and rushed forward.

The black group resisted strongly, and the tentacles on their bodies rushed towards everyone.

After being attacked by exhaust gas, the rebirth speed of the black ball's tentacles was much lower, unlike at the beginning, which was immediately restored as soon as it was interrupted.

Under the full blown attack, half of the black group's tentacles were quickly cut off.

"Woooooo!"

The black ball let out a mournful cry and pointed the tentacles with bumps at everyone. The bumps broke open together, forming a rain of pus.

"Ah!" "Ah!" "Ah!"...

The pus is extremely corrosive, and everyone who is sprayed holds the wound and wails.

Asuna reacted very quickly, dancing the sword as if it were mercury, blocking all the pus. Just as she was about to continue moving forward, an irresistible force suddenly came from her legs, and then she turned her body violently and was hung upside down. Her right foot was entangled by tentacles at some point.

Asuna was not used to this state because she had never been hanging upside down before. She failed to cut her tentacles for two consecutive strokes. She was about to take action for the third time, and countless tentacles wrapped her around her. The tentacles were deeply trapped in the delicate skin on her abdomen and thighs, tied her whole body tightly and could not use any strength at all.

"Deputy Commander!"

Seeing Asuna in danger, all the members of the Blood Alliance Knights were in a hurry. Mercenaries with good relationships with the Blood Alliance Knights also launched an alchemy attack to tie Asuna's tentacles and wanted to save her.

At this time, the situation of the black group was very bad and needed to supplement meat, so they attached great importance to the captured Asuna, activated many tentacles to block the attack, and then quickly drag Asuna into the body.

Astonished to be eaten into the black ball, Asuna closed her eyes in despair.

"Shit..."

After waiting for a long time, the imagined severe pain did not come, but a thunderous sound of blood sounded. Then my body fell, and I was soon caught by something, and the restrictions on my body were lifted.

Asuna opened her eyes curiously before she realized that she was in Li Xiang's arms.

Asuna was caught just now, Li Xiang also saw it. With the super fast speed of the Emperor Bee Armor, he hurriedly dragged Asuna into his body before the black group dragged Asuna into his body, used a high-energy sword-cutting knife to cut off the tentacles and rescue Asuna.

"Thanks."

From death to life, Asuna's mind was blank, but she just thanked Li Xiang mechanically.

"It's fine if you're fine."

Li Xiang took Asuna to the back and sat down on a broken wall, allowing her to rest.

Asuna's experience reminded everyone. They did not dare to be careless anymore, and they all used their killer moves to completely eliminate the black group.
