"Great, the vaccine has been developed!" When Guan Gu successfully developed the vaccine, he notified Xiaofeng as soon as possible, and Xiaofeng immediately rushed to him, and then Guan Gu released the news to the chief, who was even more ecstatic.

"Yes, we've saved the world, Dr. Kwan!" Pu Wenwen took off her lab coat and put down her body and mind, Mark greeted her at this time, and said with a wry smile: "Hehe, you got the vaccine, you won't need me later......"

"Wait, Professor Mark, if you want to leave, please wait for Xiaofeng to come, it's not too late." "That's fine!" Mark said helplessly.

Not long after, Xiaofeng came to the laboratory and asked Guan Gu about the specific situation.

"The vaccine takes half an hour to take effect, and it's really effective, and it can bring people back to the same way they were."

"But now there's another problem." Guan Gu asked objectively, "That is, how do we spread the vaccine to the world or even the world?" Guan Gu's words made everyone fall into deep thought, indeed, they have developed a vaccine, but how to spread the vaccine is a big problem.

"I do know a place...... Pu Wenwen stretched out a finger, "Zhixue Observatory Building, do you know?" ”

"What do you mean?" Guan Gu vaguely guessed something, but Pu Wenwen then explained: "Yes, I think we can go there and spread the vaccine antidote. ”

"The Observatory Building is a tall building in China, and it was built to observe the stars in the sky, which is why its height is high enough to avoid the influence of smog and clouds."

"When we go there, we can use the medical booster to constantly make antidotes and constantly launch them into the clouds, so that they can be spread throughout the country and even the whole world if they move along the atmosphere."

"Nice idea!" Sekiya affirmed, but said sadly, "But as far as I know, it has already fallen......"

"We can borrow troops from the chief and forcibly take it!" Pu Wenwen gave advice again. Guan Gu thought about it, this is a plan to save Huaguo and the world, and presumably the chief will agree, so he nodded.

Xiaofeng interjected: "Well, the chief will naturally do his best to help, but I still want to bring some people." ”

"Oh?" Guan Gu became interested and asked, "I don't know, who are they?" ”

"It's the people who saved you, and the people who saved me......" Xiaofeng was referring to, that is, the Rhine, Harman and others of the fusion team.

"Well, I won't go, and there's nothing left of me as an outsider." Mark added that he didn't want to follow Xiaofeng and the others to the Observatory Building anymore.

"Why? It's all this time, are you going to retreat? Pu Wenwen said a little angrily, she didn't understand Mark's current behavior too much, because it only made her think of cowardice.

"Oh, that's it! I don't want to say more. Mark felt like he wanted to speak and stopped, and Xiaofeng immediately decided to help him out: "Okay, since Uncle Mark has said so, I think Uncle is also tired, so let him go back to the old man to have a good rest." ”

"You say okay, right?" As soon as Xiaofeng's words came out, no one wanted to keep Mark, Mark looked at Xiaofeng gratefully, and then left the laboratory.

"In that case, let's get ready to start without further ado!" Guan Gu said in a grand manner, everyone nodded, and they began their plan to save the world.

Sekiya explained the situation and plan to the chief, who expressed his 100% support. He said, "Alas, if it were not for you, the civilization of our generation, would have been destroyed. ”

"Okay, I will immediately gather the forces of Yanjing and go to the Observatory Building with you, and swear to complete the task in one fell swoop."

After getting the leader's promise, Guan Gu explained to Xiaofeng, Xiaofeng nodded, and he also contacted the people of Harman's fusion team through the communication stone left by Rhine, which also explained the situation, success or failure in one fell swoop.

"Alright, let's complete the mission and return to space!" After listening to Xiaofeng's words, Harman felt that this was the fastest way to solve the catastrophe at present. At the same time, he also harbored a trace of guilt, he didn't save Xiaofeng at the first time, but fortunately, Rhine made the right decision, which led to the rapid development of the plot and made the world a lot less difficult.

After the emergency assembly, there is almost a legion of troops, of course, it is not that the chief gives less, but more people will get in the way, and it also needs troops to stay in Yanjing to prevent the attack of mutated smallpox, anyway, there is also the existence of Xiaofeng and the fusion team, and it is more than enough to complete this task.

Mark returned to the temporary shelter provided by Yanjing, he entered his room to rest, and sat on the sofa, he tugged at his hair, looking like he had a headache.

"Why, I obviously promised me, but that bastard from the Intelligence Bureau actually dared to lie to me, and still attracted the mutated smallpox to Huaguo." Mark seems to be hiding some secrets, but this has nothing to do with the status quo, and the team to save the world is already on the way to the observatory.

Along the way, the mutated smallpox encountered by killing and killing was very safe, and there was no major incident, and their destination Observatory Building, located at the junction of Yanjing and L City, is a suburban area of a prosperous commercial area, although it is not the city center, but there are a lot of mutated smallpox left, which is also the reason why Xiaofeng and they want to borrow troops from the chief.

Xiaofeng and the others sat in the car, and the team drove slowly, "Xiaofeng, do you think we can end this catastrophe?" Guan Gu suddenly opened his mouth to Xiaofeng and said, although there was no problem with the plan, he would always worry about sudden changes. Xiaofeng replied when he heard this: "Don't worry, with me, I will definitely stop this catastrophe!" Xiaofeng's eyes were so bright and powerful.

"You're still the same as college! The persistent heart has not changed! Guan Gu seemed to think of the Xiaofeng he knew in college, and he persevered, as long as it was something he identified, he would always carry it out to the end.

"You haven't changed, you don't like to exercise." Xiaofeng laughed at Guan Gu's sickly whiteness, which was really too lacking in exercise.

Rhine interjected: "Xiaofeng, when the catastrophe is over, our captain wants to talk to you!" "This is the conclusion of their previous conversation, and now it is conveyed by Rhine, they need to understand Xiaofeng before they can decide whether to be friends with him, and the team members who stabbed him in the back, they dare not ask for it.

"Don't worry, I'll talk to you about it." Xiaofeng assured, and after speaking, the car suddenly stopped.

As the car stopped, they finally arrived at their destination, the Zhixue Observatory.
