The non-combatants had withdrawn, and the flamethrower flames chased the cloud of worms that flew four times.

"Qingyun, it seems that ordinary fire can't deal with these insects, is there any other way?" Yan Zishu shouted loudly in the direction of Ning Qingyun while spitting fire.

"I don't know! Ask the professors, are there any powerful pesticides in the pharmaceutical research institute? "Ning Qingyun used black fire to deal with insects, and the efficiency was quite high, and it was only then that he knew that ordinary flames could not kill insects.

"Regiment Commander, our body armor can't support it, two people have already been bitten by bugs!" A fighter reported.

"Go to the professor outside and ask if there's any pesticides?" Yan Zishu was anxious.

At this moment, "Papapa," there was a sound of neat footsteps outside, "Great, Commander, support is coming!" ”

The new reinforcements replaced the soldiers with torn body armor, and the fire attack became more intense, although it was impossible to destroy the bugs, but the intensive fire suppression concentrated the bugs in a fixed defensive circle, unable to run around.

"Leader, Professor Fang said that this is the most toxic insecticide in the Pharmaceutical Research Institute, it is strongly corrosive, and it cannot be used to contact the skin, and if the gas mask is broken, it is best to hold your breath to prevent inhalation." The fighter who had just run to ask for the insecticide retrieved a bottle of spray.

"Give it to me!" One of the captains who came to support reached out and snatched the spray and leaped into the defensive circle.

"Stay safe." Yan Zishu admonished.

The captain made a clear gesture and walked straight towards the worm cloud.

Ning Qingyun kept mobilizing black fire to burn the roots of the withered blood tree, half of the big insects attached to the roots had been burned to ashes, and the big insects that were still active were still gushing outward, the aura in Ning Qingyun's body was gradually depleted, and he was dizzy for a while, if the insecticide could kill these insects, it might also have an effect on the big insects.

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, where there was a solid glass that could see the scene in the botanical garden.

That Professor Fang looked at the direction of the dead blood tree and muttered to himself, "No, if you continue to burn like this, you will definitely burn the tree to death, and you haven't figured out why that insect-shaped relief can turn into a live insect after it enters the ground, you 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, thinking that the army had the upper hand, but Rong Xian Xian saw that the aura in Ning Qingyun's body was not continuous, and the situation over there was not optimistic.

She saw Professor Fang walking out, took a few steps to stop in front of him, and waved one hand in front of him, Professor Fang's body weakened, and he fell backwards, Mingyan had already received Rong Xianxian's signal, and supported Professor Fang before he fell to the ground.

"What are you doing?" The students led by Professor Fang glared at Rong Xian Xian and asked.

"What are you doing?" Shen Lishu took a few steps forward and stood not far from Rong Xian Xian.

There were also more than a dozen members of the Tianhe Mercenary Regiment who had just left the room to rest, and they all stood up when they saw this scene, staring in the direction of the scientific researchers.

"Mingyan, protect Xuanxuan and Xiaoluo, no one is allowed to step out of the room until the crisis is resolved!" After Rong Xian Xian finished explaining, he left the room and walked in the direction of the Withered Blood Tree.

"What can a woman do?" A researcher who picked up Professor Fang muttered dissatisfiedly.

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

The man looked around, and when he saw that there was no one to help, he shut his mouth stupidly.

Rong Xian Immortal went straight to Ning Qingyun's side and stuffed a spirit stone into his hand.

She pointed her palm at the root of the tree with the large worms that kept gushing blood nematodes, and the cold power poured out, and those large insects were frozen together with the blood nematodes that kept gushing out.

Ning Qingyun took this opportunity to quickly absorb the spiritual energy in the spirit stone, but in just a moment, the empty meridians in his body filled up again.

Before, the blood nematodes continued to fly out from the roots of the tree, the insecticide had no effect on the blood nematodes at all, and the cloud of flakes of insects gradually gathered into a sea of insects, suppressed by firepower, and the defensive circle composed of flamethrower spray was gradually unable to maintain, Yan Zishu had been paying attention to the source of insects at the roots of the tree, and the situation of Rong Xian Xian Xian's shot to freeze the blood nematodes had already fallen into his eyes, Yan Zishu was overjoyed, "Doctor Rong, come here to support, we can't stand it!" ”

Rong Xian Xian did not hesitate, walked into the defensive circle, and released the cold power of the sea of insects, accompanied by a slight "click" sound, the sea of insects gradually froze, and the blood nematodes with wings and covered with scales were frozen in the ice.

Rong Xian Xian looked at the fiery eyes around her, and said calmly, "This ice layer can only trap these insects for three minutes at most, and after three minutes, you have to continue to suppress the fire!" ”

I don't know what kind of breed these insects are, their vitality is very tenacious, and the ice layer created by Rong Xian Xian can only trap them, and the larger the range of the ice layer, the less lethal the power of the ice power.

"Ahh Someone screamed in disappointment.

"Check your weapons, reload your ammo, take a break, and get ready for another fight." Yan Zishu ordered.

Rong Xian Xian used the power of ice to create ice, buying time for Ning Qingyun and Yan Zishu to take an intermission and replenish energy to restore their aura, and finally cleared all the blood nematodes with the joint efforts of everyone.

After this crisis, everyone was exhausted.

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

"Do you have any secret weapons?" Yan Zishu leaned in front of Ning Qingyun and asked him in a low voice.

"In that dead forest, I can run out, here, I'm afraid that these insects will run out, can the difficulty be the same?" Ning Qingyun replied.

Even if you are a close friend, you must never reveal the secrets that should be kept.

"Today we can solve this crisis thanks to the two of you husband and wife working together, one is frozen and the other is burned, and the match is perfect." Yan Zishu sighed and said that these insects can't be hit by guns, they can't be burned by fire, they are small in size, they can fly, and they can make people lose their minds when they get into the human body, which is really terrifying.

This botanical garden was originally planted with many rare medicinal herbs, all of which were robbed of life by the roots of the dead blood tree.

The botanical garden is full of dead branches and leaves, and there are many patches of black ash left by the fire, and there are bullet holes from various types of bullets on the ground.
