The non-combatants had evacuated, flames from flamethrowers chasing four clouds of flying insects.
"Qingyun, it seems that ordinary fire can't deal with these insects. Is there any other way?" Yan Zishu shouted in the direction of Ning Qingyun while breathing fire.
"I don't know! Ask those professors if there are powerful pesticides in the Pharmaceutical Research Institute?" Ning Qingyun used black fire to deal with bugs, and it was very efficient. It was only then that he realized that ordinary flames could not kill them. insect.
"Captain, our body armor can no longer hold up, and two people have been bitten by bugs!" a soldier reported.
"Go to the professor outside and ask if there are any pesticides?" Yan Zishu was worried.
At this moment, "Bah, bang, bang," the sound of neat footsteps came from outside, "Great, captain, support is here!"
The new support team replaced the soldiers with damaged body armor, and the fire attack became more fierce. Although these bugs could not be eliminated, the intensive fire suppression concentrated these bugs in a fixed defense circle, preventing them from running around. .
"Leader, Professor Fang said that this is the most toxic pesticide in the pharmaceutical research institute. It is highly corrosive and should not come into contact with the skin when using it. If the gas mask is damaged, it is best to hold your breath to prevent inhalation." He just ran away The soldier who asked about the pesticide returned with 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.
"Pay attention to safety." Yan Zishu warned.
The captain made a clear gesture and walked straight towards the insect cloud.
Ning Qingyun kept mobilizing black fire to burn the roots of the withered blood tree. Half of the big bugs attached to the roots had been burned to ashes. The other big bugs that were still active were still spewing out. The spiritual energy in Ning Qingyun's body gradually dried up. , I feel dizzy in front of my eyes. If pesticides can kill these bugs, it may also be effective on big bugs.
After Rong Xianxian handed the flamethrower to Yan Zishu before, she took the children and the scientific researchers to stay in the drug research room outside the botanical garden. In this room, there is a solid glass that can see the scene in the botanical garden.
Professor Fang looked at the direction of the dead blood tree and murmured to himself, "No, if it continues burning like this, the tree will definitely be burned to death. I still don't understand why the insect-shaped relief can become alive after being buried in the ground." Bugs, we can't let them burn the tree to death like this!" He muttered as he opened the door and walked out.
The old professor only saw the flames over there and thought that the army had the upper hand. However, Rong Xianxian saw that the spiritual energy in Ning Qingyun's body was not continuing and the situation there was not optimistic.
When she saw Professor Fang walking out, she took a few steps to stop him and waved one hand in front of him. Professor Fang's body softened and fell backwards. Mingyan had already received Rong Xianxian's signal and was standing in front of him. Professor Fang supported him before he fell to the ground.
"What are you doing?" The students led by Professor Fang glared at Rong Xianxian and asked.
"What are you doing?" Shen Lishu took a few steps forward and stood not far from Rong Xianxian.
There were more than a dozen members of the Tianhe Mercenary Group in the room who had just left to rest. Seeing this scene, they all stood up and stared in the direction of the scientific researchers with unkind eyes.
"Mingyan, protect Xuanxuan and Xiaoluo. No one is allowed to step out of the room until the crisis is over!" After Rong Xianxian finished her explanation, she left the room and walked towards the withered blood tree.
"What can a woman do?" A researcher who took Professor Fang over muttered dissatisfiedly.
Shen Lishu took a few steps forward and grabbed the man's clothes, "How about that? You go."
The man looked around and saw no one was helping him, so he closed his mouth angrily.
Rong Xianxian came straight to Ning Qingyun and put a spiritual stone into his hand.
She aimed her palm at the big bugs that were constantly spewing out blood worms at the roots of the tree, and the cold power poured out. Those big bugs, together with the blood worms that kept spewing out, were frozen.
Ning Qingyun took this opportunity to quickly absorb the spiritual energy in the spirit stone. Within a moment, the empty meridians in his body were filled again.
In the past, blood nematodes were constantly flying out from the roots of trees. Insecticides were completely ineffective against blood nematodes. The clouds of insects gradually gathered into a sea of worms. The defense circle composed of fire suppression and flamethrower spray could no longer be maintained. , Yan Zishu has been paying attention to the source of insects at the roots of the trees. The situation of Rong Xianxian attacking the frozen blood worms has long fallen into his eyes. Yan Zishu was overjoyed and said, "Doctor Rong, come here for support, we can't hold it anymore!" "
Rong Xianxian did not hesitate, walked into the defensive circle, and released the power of ice at the sea of insects. With a slight "click" sound, the sea of insects gradually froze, with wings one after another and blood covering their scales. Nematodes freeze in the ice.
Rong Xianxian faced the fiery looks around her and said calmly, "This ice layer can only trap these bugs for three minutes at most. After three minutes, you have to continue to suppress them with firepower!"
The species of these insects is unknown, but they are very tenacious. The ice layer created by Rong Xianxian can only trap them, and the larger the area of the ice layer, the less lethal the power of the ice.
"Ah!" Someone screamed in disappointment.
"Check the weapons, refill the ammunition, take a short rest, and prepare to fight again." Yan Zishu ordered.
Rong Xianxian used the power of ice to create an ice layer, giving Ning Qingyun and Yan Zishu time to rest and replenish energy to restore their spiritual energy. Finally, with the joint efforts of everyone, all the blood worms were eliminated.
After this crisis, everyone was exhausted.
Yan Zishu panted and said to Ning Qingyun, "This dead blood tree is so difficult to deal with. I really can't imagine how you got out of the dead forest?"
"Do you have any secret weapons?" Yan Zishu approached Ning Qingyun and asked him in a low voice.
"In that dry forest, I can run outside, but here, I am afraid that these bugs will escape. Can the difficulty be the same?" Ning Qingyun answered.
Even if you are a close friend, you should never reveal the secrets you should keep.
"This crisis can be solved today thanks to the two of you working together. One is frozen and the other is burned. The combination is perfect." Yan Zishu sighed and said that these insects cannot be shot with a gun or burned to death. They are small in size and can fly. , drilling into the human body can make people lose their minds, which is really terrible.
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 trees.
There are dead branches and leaves everywhere in the botanical garden, and there are many pieces of black ash left by the fire. There are bullet holes on the ground made by various types of bullets. It used to be lush and full of exotic flowers and plants. The botanic gardens now look very rundown.
