Good. Rong Xianxian agreed, picked up the two children and walked out.

"Boom", a slight sound of flapping wings came, Ning Qingyun's face changed in an instant, and he saw a small red dot flying towards Rong Xian Xian, and flew to her in the blink of an eye, "Immortal, dodge quickly." ”

Ning Qingyun shouted and flew towards Rong Xianxian's position.

Rong Xian Xian staggered to the side, and Ning Qingyun's fingertips flashed with black fire, burning the little red dot into black ashes.

Rong Xian Xian's mother and son were neither wearing protective clothing nor gas masks, in case they were drilled into their bodies by red worms, it would be dangerous, Ning Qingyun had palpitations for a while, "Immortal, come to me."

"What's going on?" Rong Xian Xian couldn't help but get nervous when she saw Ning Qingyun's appearance as if she was facing a great enemy.

"You have hazmat suits and gas masks on you?" Ning Qingyun did not answer the rhetorical question.

"Yes!" Rong Xian Xian nodded, these things are necessary in the sachet space.

"Get dressed!" Ning Qingyun urged.

"Qingyun, what do you think is going on?" Yan Zishu looked at the two people who had just excavated the roots of the tree and stood still as if they were lost in their minds, and then they kept circling around the withered blood tree, and turned back to ask Ning Qingyun.

"See those red bugs popping up at the roots of the trees? That kind of thing is called blood nematodes, those blood nematodes burrow into the human body and can release substances that lose their minds, these blood nematodes should hatch in the worm-shaped relief at the root of the dead blood tree, and must be eliminated as soon as possible! Ning Qingyun said as he said while the task required the tree to keep the root system intact, before Ning Qingyun brought this dead blood tree back to the capital, he only split an insect-shaped relief in the most hidden place at the edge of the root system, and after splitting it, it was an ordinary wooden texture, and there was nothing special about it, so Ning Qingyun felt that although there was something wrong with the live insects turning into reliefs, it should not be dangerous to use them for research, but he didn't expect that after planting the dead blood tree into the soil, it would hatch live insects.

"These bugs can fly! So what now? Yan Zishu asked eagerly, Ning Qingyun had dealt with these insects, and he should know more about these insects.

Most of the soldiers brought by Yan Zishu were dressed in leather armor or body armor and defensive helmets, and they were not afraid of being attacked by blood nematodes for a while.

"Evacuate the people around the Dead Blood Tree, find a way to fence this area, and I'll uproot the tree later, and you can use flamethrowers to burn these bugs." Ning Qingyun used black fire to burn many blood nematodes when he was in the dead forest, after all, this is not a dead forest, there are not so many insects, as long as it is dealt with in time, it should not cause too much harm.

As Ning Qingyun spoke, he used black fire to burn the insects that kept popping up at the roots of the tree.

"Wei Chong, send a message to Regiment Commander Zheng, quickly send the nearest firearms battalion to support, the first team immediately took the non-combatants out of the scene, the second team used a microgrid to fence off this area, and the third team was ready to shoot." Yan Zishu gave the order, and the soldiers quickly moved into action.

"Major Yan, the small root system of this tree can suck blood, and now the underground root system is expanding rapidly, if it breaks through the Pharmaceutical Research Institute and reaches a crowded place, the roots of the tree will be fed by more blood, which will make the roots of the tree more powerful, and the main root system of this tree must be dug out as soon as possible, so as to prevent the spread of the underground root system." After a brief period of panic, based on the situation at the scene, the researchers quickly deduced the great danger of the underground root system.

He believes that these blood nematodes can only temporarily disorient people, and the frenzied expansion of the underground root system that can absorb life is the biggest danger.

"Qingyun." Yan Zishu looked at the large areas of dead plants, and didn't know what to do.

"I can pull this tree out alone, but after pulling out the tree, we may face a sea of insects attack, and the existing firepower may not be able to stop the spread of the sea of insects." Ning Qingyun had already eliminated most of the blood nematodes at this moment, and Ning Qingyun was also terrified as he watched the withered yellow area continue to expand.

It seems that the reason why large dead forests are formed is because the dead blood trees suck the vitality of other plants.

"There is only one tree here, and if it has been planted for such a short time, how can it form a sea of insects? On the contrary, the more it drags on, the more likely it is to hatch more bugs, I just checked the two warriors who were attacked by blood worms, there is nothing wrong with the body, just temporarily lost consciousness, and it will soon recover, don't hesitate, hurry up and pull out the tree! The professor said eagerly.

Seeing that the withered yellow area had crossed the botanical garden and spread to the front yard of the Pharmaceutical Research Institute, Yan Zishu gritted his teeth and made a decision, "Qingyun, come on!" ”

Ning Qingyun thought for a moment, what the professor said was right, and saw that Rong Xian Xian and the two children had already put on protective clothing and gas masks, and nodded.

He put the rope around the root of the tree and pulled it up hard, obviously it was a tree that had just been planted, the soil was fresh and moist, but it was extremely laborious to pull it up, Ning Qingyun used all his strength, and finally shook the root system of the withered blood tree.

"Qian Qi, bring a few brothers over to help." Yan Zishu saw that some of the brothers in the team responsible for evacuating the crowd had returned, and immediately called for their help in uprooting the trees.

With the efforts of everyone, the dead blood tree was pulled out, and the original insect-shaped reliefs at the roots of the tree had come to life at this time, turning into hideous big insects, and small flying red worms gushed out in clusters of these big insects, endlessly, as if endless.

"Shoot! Focus your fire on those big bugs, fast. Yan Zishu roared loudly.

"Bang bang bang," gunshots rang out everywhere, gunsmoke filled the air, "buzz," the dense sound of flapping wings echoed in the ears, and dense red worms formed a cloud of red clouds and launched an attack on the surroundings.

"Azusa, don't you have a flamethrower in the team? Bullets are useless against these bugs, they must be burned with fire! Ning Qingyun said to Yan Zishu while burning the big insects attached to the roots of the tree with black fire.

"Nope! Support staff are not yet in place, and the microgrid will not last long. Yan Zishu looked at the uncertain red clouds, and was anxious.

"I have, for you." Rong Xian Xian handed a flamethrower to Yan Zishu, and the cylinder connected to the flamethrower was full of fuel.

Yan Zishu was overjoyed, and immediately aimed at the red cloud that flew over and breathed fire, the flames surged out, and quickly shrouded the red cloud, however, I saw that the red cloud that was shrouded was scattered into four or five groups and flew out in the flames, Yan Zishu aimed at the scattered group and continued to spray, and this group also flew out of the fire, the flames were blazing, but it couldn't burn these red worms at all, and the red clouds were divided and combined, and there was no reduction at all.
