Chapter 496 Chapter 498
The non-combatants had been evacuated, flames from the flamethrowers were chasing the cloud of four flying worms.

"Qingyun, it seems that ordinary fire can't deal with these bugs, is there any other way?" Yan Zishu shouted towards Ning Qingyun while breathing out fire.

"I don't know! Ask those professors, is there any powerful insecticide in the Institute of Pharmaceutical Sciences?" Ning Qingyun used black fire to deal with insects, and the efficiency is quite high. It is only now that he knows that ordinary flames can't kill them. insect.

"Regimental Commander, our body armor can no longer hold up, and two people have already been bitten by bugs!" a soldier reported.

"Go to the professor outside and ask if there is any pesticide?" Yan Zishu was devastated.

At this moment, "Papa Papa," came the sound of neat footsteps outside, "Great, Captain, support is here!"

The new support team replaced the soldiers with broken body armor, and the fire attack became more intense. Although these bugs could not be eliminated, the intensive fire suppression concentrated these bugs in a fixed defensive circle, and they could not scurry around. .

"Leader, Professor Fang said that this is the most toxic insecticide in the Institute of Pharmaceutical Sciences. It is highly corrosive and should not touch the skin when using it. If the gas mask is damaged, it is best to hold your breath to prevent inhalation." Just ran The soldier who asked about the insecticide took back a bottle of spray.

"Give it to me!" A captain who came to support reached out and grabbed the spray and jumped into the defensive circle.

"Be careful." Yan Zishu warned.

The captain made a clear gesture and walked straight towards Chongyun.

Ning Qingyun kept mobilizing black fires to burn the roots of the dead blood tree. Half of the big worms attached to the roots were burned to ashes. In addition, the big worms that were still active were still spewing out, and the aura in Ning Qingyun's body gradually dried up. , dizzy for a while, if the insecticide can kill these bugs, it may also be effective for the big bugs.

After Rong Xianxian handed over the flamethrower to Yan Zishu, she took the children and researchers to stay in the drug research room outside the botanical garden. In this room, there is a strong glass to see the scene inside the botanical garden.

That Professor Fang looked at the flames in the direction of the dead blood tree, and muttered to himself, "No, if the fire continues like this, the tree will definitely be burned to death. Worms, we can’t let them just burn the tree to death!” He muttered as he opened the door and walked out.

The old professor only saw the flames rising into the sky over there, thinking that the army had the upper hand, but Rong Xianxian could tell that the spiritual energy in Ning Qingyun's body was not continuing, and the situation over there was not optimistic.

Seeing Professor Fang walking out, she took a few steps to stop in front of him, and waved one hand in front of him. Professor Fang's body softened, and he fell backwards. Professor Fang supported him before he fell to the ground.

"What are you doing?" Professor Fang's students glared at Rong Xianxian and asked.

"What are you doing?" Shen Lishu stepped forward and stood not far from Rong Xianxian.

There were more than a dozen members of the Tianhe Mercenary Corps who had just left for a rest in the room. Seeing this scene, they all stood up and stared in the direction of the researchers with bad eyes.

"Mingyan, protect Xuanxuan and Xiao Luo, and no one is allowed to step out of the room until the crisis is over!" Rong Xianxian left the room and walked towards the withered blood tree after explaining.

"What can a woman do?" A researcher who took Professor Fang over mumbled dissatisfiedly.

Shen Lishu took a few steps forward and grabbed the man's clothes, "How about? You go."

The man looked around and saw that there was no one to help, so he closed his mouth resentfully.

Rong Xianxian went straight to Ning Qingyun and stuffed a spirit stone into his hand.

She pointed her palm at the big worms that kept gushing out blood nematodes from the root of the tree, and the power of ice poured out, and those big worms, together with the blood nematodes that kept gushing out, were frozen in ice.

Ning Qingyun took this opportunity to quickly absorb the aura in the spirit stone, and within a short while, the empty meridians in his body filled up again.

Before the blood nematodes flew out continuously from the roots of the tree, the insecticides had no effect on the blood nematodes at all, and the cloud of flakes gradually gathered into a sea of ​​insects. The defensive circle composed of suppressed firepower and flamethrowers could no longer be maintained. , Yan Zishu has been paying attention to the source of insects at the root of the tree, and the scene of Rong Xianxian's action to freeze the blood nematodes has already fallen into his eyes, Yan Zishu was overjoyed, "Doctor Rong, come here to help, we can't stand it anymore! "

Without any hesitation, Rong Xianxian walked into the defense circle and released icy power at the sea of ​​worms. With a slight "click" sound, the sea of ​​worms gradually froze, and each of them had wings and covered with scales. The nematodes are frozen in the ice layer.

Faced with the fiery eyes around him, Rong Xianxian said calmly, "This ice layer can only trap these bugs for 3 minutes at most. After 3 minutes, you have to continue to suppress them with firepower!"

I don't know what species these bugs are, and their vitality is very tenacious. The ice layer created by Rong Xianxian can only trap them, and the larger the ice layer is, the smaller the killing power of the ice will be.

"Ah!" Someone screamed in disappointment.

"Check the weapons, fill the ammunition, take a short rest, and prepare for another battle." Yan Zishu ordered.

Rong Xianxian used the power of ice to create an ice layer, bought Ning Qingyun and Yan Zishu time for intermission and replenish energy to recover their aura, and finally wiped out all the blood nematodes with the joint efforts of everyone.

After this crisis, everyone is exhausted.

Yan Zishu panted and said to Ning Qingyun, "This withered blood tree is so difficult to deal with. I really can't imagine how you got out of the withered forest?"

"Do you have any secret weapon?" Yan Zishu approached Ning Qingyun and asked him in a low voice.

"In the dead woods, I can run outside. Here, if these bugs run out, can it be the same difficulty?" Ning Qingyun replied.

Even if it is a close friend, the secret that should be kept must not be revealed.

"Today, this crisis can be resolved thanks to your husband and wife teaming up. One is frozen and the other is burned. The match is perfect." Yan Zishu sighed and said, these insects cannot be shot or burned, they are small in size, and they can fly. , It is really terrifying to penetrate into the human body and make people lose their minds.

Many rare medicinal herbs were originally planted in this botanical garden, but all of them were robbed of their vitality by the roots of the dead blood tree.

The botanical garden is full of dead branches and leaves, and there are many pieces of black ash left by the fire. There are bullet holes made by various types of bullets on the ground. The botanical garden looks very dilapidated now.
