Lei Aotian worked hard to carry the materials to the underground.

The biochemical zombie catastrophe has come.

After another half an hour of transportation, Leng Xuanmeng actually stopped carrying materials.

"The Inquisition has sent us a new mission!" The cold dream sent a message to Lei Aotian.

"What's the mission?"

"Go to the orc territory prairie, reach the dimensional world where the zombies are located through the spatial passage, and collect blood samples of the older zombies in the zombie world." The cold dream returned.

After Lei Aotian heard this, he no longer carried supplies.

"Can you not go, this is a death mission. Why give us the squad, the other Inquisitor squads! Lei Aotian asked rhetorically.

"We must go, in order to save the Falling Dragon Continent, and for our own future. The infirmary in the Inquisition Fortress is now taking samples of zombie blood that are too new. Blood samples from older biochemical viruses could help the Inquisition Institute develop a vaccine. We're in the Chosen City, closer to the teleportation of the savannah than the other Inquisitors, so the Inquisition sent our team! Leng Xuanmeng explained.

Lei Aotian felt that the cold dream was a fool to be a judge, and he only knew that he would obey the task and send him to death.

Of course, if the trial can develop a vaccine 100% based on the blood of older zombies, this mission of death is worth it.

But now obtaining the blood of the more ancient biochemical zombie virus will only help the Inquisition Institute to develop a vaccine, and it may not be successful.

"Fifteen kilometers outside the Imperial City of the Heavenly Dragon Empire, isn't there also a teleportation channel to the zombie world, isn't it the same for the Inquisition to send mecha to enter from there!" Lei Aotian asked rhetorically.

"Half an hour later, the valley barrier where the zombies of the Celestial Dragon Empire are located will disappear. After the Dragon Emperor controls the Imperial City Formation Strike, the Mecha Warrior will also enter the teleportation channel to collect blood samples. Although the teleportation passage on the orc grassland and the teleportation passage outside the Chosen City both lead to the zombie world, they should be two places. Now in the early stage of the outbreak of the biochemical zombie virus, obtaining as many blood samples as possible from the zombie world will help the subsequent vaccine development and prevention and control of the zombie virus. Leng Xuanmeng said.

Leng Jiemeng took Lei Aotian and quickly returned to the underground passage, and found two small silver-white metal boxes in a medical equipment room under the underground shuttle track.

In the small boxes, each box has a hundred empty glass syringes.

These empty needles are placed in the Dragon Empire in the apocalyptic world to give advance vaccinations to people who go to the apocalyptic world.

There are also viruses in the apocalyptic world, although they are not as harmful as the zombie virus, but the fatality rate after infection is not low.

Before the infiltrators of the Falling Dragon Continent come to the Falling Dragon Continent from the apocalyptic world, they will be vaccinated and undergo a strict physical examination to avoid bringing the virus into the Falling Dragon Continent.

People who were going to the apocalyptic world in the Fallen Dragon Continent before would also be required by the trial to inject some vaccines in the Falling Dragon Continent before they were allowed to take a double-track shuttle train to the apocalyptic world.

"Bring it with you, hang it on the left waist of the mecha, and be careful not to break it when you fight." Leng Xuanmeng said, handing Lei Aotian a box of empty needles.

"We're going to the zombie world to draw the blood of two hundred ancient zombies? How can you tell which zombies are infected with older viruses in the zombie world? Lei Aotian also learned to break off his dreams coldly, and asked after hanging the small metal box on the left waist of the mecha.

"After we enter the zombie world, let's go deeper according to the actual situation and randomly select some zombies with special appearances. We don't have the equipment to tell which zombie infected person has an older virus, so we can only leave it to fate. We'll just draw the blood of 200 different zombies and send them back to the infirmary under the Inquisition for study. Leng Jiemeng said, he had already controlled the mecha to turn around, took Lei Aotian and Feng Thirteen, and quickly walked towards the stairs and walked towards the exit.

The metal plates and ceilings on both sides of the underground staircase passage were lit with white lights, and Lei Aotian looked at the cold dream in front of him who led the way in a hurry, and only then did he know that he went to the apocalyptic world to draw zombie blood, and it turned out that he had hit a big luck.

If the zombie blood of infected person zero can be drawn, it is estimated that the medical room below the inquisition will progress faster in studying the biochemical zombie virus.

Lei Aotian suddenly thought of a dangerous thing.

"If the zombie virus can spread through the air, we will enter the plane where the zombie world is located, and the concentration of the virus there will definitely be higher than the current Falling Dragon Continent. What if we get infected and become zombies? Didn't the Inquisition provide us with special protective clothing? Lei Aotian asked.

"The mecha has its own air filtration device, which should be able to filter some biochemical viruses. But if we are really accidentally infected, try to send the needle containing the blood of the zombie back to the Falling Dragon Continent before we die, and it will be considered valuable to die! Leng Xuanmeng said casually.

After hearing this, Lei Aotian felt that his fiancée's answer was different from what he wanted to ask.

"Sister Leng, I haven't gotten married yet, and it's valuable if I don't want to die!" Lei Aotian directly expressed his attitude this time, looking ahead, the three of them had already walked out of the underground passage.

After coming out of the underground passage, Leng Xuan Meng pressed the hidden switch on the pillar next to him to turn off the metal plate leading to the entrance to the underground passage.

Two huge metal plates, starting to "squeak and squeak!" The movement of the slow closure on.

From the outside, it has once again become a normal warehouse floor.

"Don't run away, Lei Aotian, from the day you joined the Inquisition, you have been the warrior who guarded the Fallen Dragon Continent, you can recall the oath you took when you joined the Inquisition. If this zombie virus can really spread through the air, it is still contagious, even if we are afraid of dying this time and will not go to the zombie world, we will avoid infection. Most of the people in this Fallen Dragon Continent will soon be infected and become zombies. It won't be long before the virus concentration of the Falling Dragon Continent and the Zombie World will be similar, and then the Falling Dragon Continent will become the second Zombie World. ”

"Oh, well, go save the world. But Sister Leng, I didn't take an oath when I joined the Inquisition, what an oath! Lei Aotian said.

"Sister Leng, I didn't take an oath either, do you still have an oath to join the Inquisition!" Feng Thirteen, who was following on the side, also asked.

Leng Duanmeng coughed dryly, "If you become a judge, you have to take an oath, and I will make up for your oath to join the inquisition in the future, Feng Thirteen, sit on the left shoulder of my mecha, and we will fly to the orc prairie." ”

Feng 13 sat on Leng Duanmeng's shoulders again, and the two mechs rose into the air.

"Is there anyone answering us?" Lei Aotian asked Leng Xuanmeng through the team channel.

"Yes, the Inquisition has communicated with the big demon, and this time there will be a big demon of the demon clan to assist us in entering the zombie world and extracting the blood of the zombies."

Hearing this answer, Lei Aotian was somewhat relieved.
