"Okay, then you have to be careful." Ding Ning nodded and ran to the top floor.

The security personnel on the top floor could not withstand the ninja's attack, so the two had to split into two groups to help.

Before leaving, Ding Ning threw two silver needles and hit the two more powerful ninjas.

Their bodies suddenly became stiff and could only be beaten by a group of security personnel on the turn of sticks, and were beaten to the point where they were gone.

Shao Yuxuan's move was also very sharp, one punch, and the strength of the fist was enough to knock out the ninja's teeth.

Shao Yuxuan's morning exercise method given by Ding Ning unknowingly improved his strength, and he could not withstand a single punch.

When Ding Ning came to the roof, the scene above was no different from the scene below. The security personnel and the ninja had already fought together.

Several members of Shao Yuxuan also killed several ninjas.

These ninjas are very low-level ninjas. Ding Ning is just like dealing with them, and it is not difficult for him to deal with children.

With Ding Ning's joining, the ninjas couldn't hold on and were beaten to death.

One of the ninjas raised the samurai sword and tried to stab Ding Ning in the chest, but Ding Ning blocked the blade with one hand.

"Bang!!!"

A crisp sound rang out, and the samurai sword in the ninja's hand was broken by Ding Ning with one hand.

Seeing this, several ninjas were scared and their faces were pale, and their eyes were filled with fear.

"Go! Get rid of them!"

A group of security personnel rushed up with sticks and served the ninjas with sticks.

It cannot be said that these ninjas are very weak. They can only say that they underestimated the combat effectiveness of security personnel, so that they could only get beaten.

"Ding Ning, the people below have been solved. How is the top floor?" Shao Yuxuan's voice came from the headset.

"I have solved all this, are there any casualties below?"

"The dead are all ninjas, and our people are just a little injured." Shao Yuxuan said.

Ding Ning looked around and found that there were only injuries on the top floor, and no one died.

"Put them all in, and someone may sneak in."

"clear!"

Ding Ning was about to go downstairs to find the whereabouts of other ninjas. Halfway through, he reached out and penetrated the ventilation duct above his head.

Then he pulled a ninja down and kicked him over.

After taking this ninja to the top floor, Ding Ning went elsewhere to see if there were any missing ninjas.

Ding Ning met Shao Yuxuan on the fifth floor. She hurried over with something and asked, "Ding Ning, look, I found this thing in them. Could it be that there are people outside commanding all this?"

"Not care about this for now. We have to clean up the inside of the research institute first, and people outside will talk about it later."

"good!"

Fortunately, it is the Metropolitan country here, and ninjas dare not appear on a large scale, but just sent out a team of only more than twenty people.

Their infiltration plan was instantly lost because they underestimated the defensive ability of the security personnel in the institute, and there was also Ding Ning.

The institute was quickly cleaned up, and there were no other ninjas except those caught.

Shao Yuxuan conducted the last question and confirmed that there were no ninjas in the institute and that the institute had restored safety.

"Now, send someone to repair the route quickly." Shao Yuxuan explained.

"Yes! Let's go to the distribution room for inspection immediately!"

"OK!"

At this time, the laboratory also received news from outside, and the suspended experiment could finally continue.

"It's me, Yu Xuan, open the door!"

"Go and open the door for Captain Yu!" Professor Qian said.

"yes!"

The scientific researchers inside opened the door, and Ding Ning and Shao Yuxuan both walked in.

Professor Qian asked anxiously, "Captain Yu, what's going on outside? Is there any danger?"

"All the ninjas that have penetrated into the institute have been controlled and are temporarily safe. When the power system is restored, the experiment can continue."

"Very good!"

Professor Qian sighed with a sigh of relief. It seemed that his choice to decide to return to Dadui to continue scientific research.

Only your own motherland can give you the best protection.

After about half an hour, the power system finally recovered and the laboratory also returned to brightness.

Professor Qian rubbed his hands and said, "Let's carry out the last stage of the experiment!"

"OK!"

A scientific researcher brought a cage containing a sick white mouse, but the cage seemed to be very strong.

Professor Qian said with the guinea pig, "This guinea pig is a diseased mouse that we took a long time to find. It suffers from multiple diseases and is almost on the verge of death."

The little mouse no longer moves, and there are many secretions around it. It can be said that the only thing this little mouse can do is breathe.

The researchers mounted the camera and began to record the experiment.

The mouse was put into a sealed box, and Ding Ning and Shao Yuxuan could also watch it. Professor Qian took out a test tube in the refrigerator, sucked serum with a syringe, and then injected it into the mouse's body.

"Ding Ning, do you think this experiment will be successful?" Shao Yuxuan asked.

"I don't know, it may succeed?"

Ding Ning did not give an answer. If this kind of serum was really developed, the warrior would feel very uncomfortable.

Because some warriors are already very powerful, so powerful that they can threaten the security of the country, they have established a world outside the country.

It is not said that only warriors in the capital are there, but even other countries have many talented people.

Comparing the superpowers of M Country and the unknown creatures in the world, in the face of these, ordinary people are like ants. Once Professor Qian’s serum research is successful, it means that ordinary people can also suppress those talented people.

The country of Dadu is still good. Warriors have special checks and balances. Everyone abides by such rules, but foreigners are different. Some psychics have begun to interfere in national politics, which is the most taboo thing for a country.

After the serum injection, the mice did not show symptoms. Instead, all instruments issued alarms, indicating that the mice's various life indicators and heartbeat were decreasing sharply.

"This..." Professor Qian was immediately disappointed.

The researchers were also stunned and looked at this scene in disbelief. Could it be that they failed after so many years of hard work?

Professor Qian naturally didn't believe in your result. He kept reflecting on where the mistake was made. Could it be that the subject's body was too weak to withstand the injection of serum?
