The three of them struggled to reach the foot of the second layer of the mountain, and the black ghost told Liu Yifeng and Zhang Mazi to wait at the bottom of the mountain, and rushed to the stone wall alone.

The black ghost found an opportunity, and with a flying step, he went up to the stone wall, took out his waist knife, and quickly eliminated the four guards. The Black Ghost hid their corpses and hid in a dark corner.

The patrolling Wako turned around and found that the four soldiers who had been guarding here had disappeared, and immediately sent people to look for them. The Black Ghost saw the moment again and threw the five throwing knives pinned to his waist at the five soldiers who had come to search. The five flying knives went straight to the point, and the five people did not fall to the ground immediately after being stabbed, but stood in the same place.

"Hey, what are you doing?"

The commander in the back couldn't stand it anymore, so he went up and kicked one of them in the ass, and the wolf fell directly to the ground.

"Alert!"

The commander immediately shouted to all the Japanese guards behind him, but he could only shout this one.

The Black Ghost immediately rushed forward and slit the commander's throat with a dagger. The Wokkers watched their commander have their throats slit by the Black Ghost, and everyone did not dare to act rashly, they had all heard of the reputation of the Black Ghost and did not want to make him angry.

The black ghost will not be merciful, after all, he is an assassin, and in the face of this situation, the black ghost raised his knife and eliminated all the remaining guards.

Then, the black ghost didn't give Liu Yifeng and them a gesture and beckoned them to come up. After Liu Yifeng saw the signal, he and Zhang Mazi followed.

The three of them crossed the stone bridge and entered the camp of Hushi Mountain. Zhang Mazi and Liu Yifeng didn't know how to fly the eaves and walk on the wall, so the two of them changed into the clothes of the guards, and the black ghost was still wearing night clothes, and the three of them acted separately and gathered at the stone wall an hour later.

Because the stone bridge was blown up before, the Japanese of Hushi Mountain also lost their vigilance against Liu Yifeng, and when they learned the news that Liu Yifeng was killed, they did whatever they wanted, except for the guards on the stone wall, there was not a single soldier in the patrol in the barracks, and all of them went back to sleep.

"Brother Feng, don't we mean to take off our pants and fart, no one patrols either."

Zhang Mazi looked at the empty Japanese barracks, and always felt that something was missing. But Liu Yifeng didn't think that their disguise was superfluous, and he gave Zhang Mazi a kick when he went up.

"Don't talk nonsense, hurry up and find it, Hu Zhao is still waiting at home."

The three of them immediately launched a search in the barracks, and soon, all three of them simultaneously locked their eyes on the medical depot of the Wako. The three of them walked into the warehouse together, and the medicines on the shelves were dazzling, which was quite spectacular.

The three of them didn't think much about it, and immediately looked for drugs with the word tranexamic acid. Thousands of medicines are also terrible to find, Zhang Mazi looked at the big head, the bigger the head, the more he didn't want to look for it, and finally simply sat on the ground and watched Liu Yifeng and the black ghost look for it.

But just this one, really sitting right, there is a very thick iron box at the bottom of the shelf, Zhang Mazi felt strange, so he pulled the box out. The box fell to the ground with a clatter, which frightened Liu Yifeng and the black ghost, and they immediately looked around and breathed a sigh of relief when they found that there was no enemy.

Liu Yifeng ran to Zhang Mazi and slapped him hard, and scolded in a low voice:

"You're crazy, you want to fucking kill us!"

"Ouch, it hurts! Brother Feng, look at what this is, why is there such a big iron box. ”

Liu Yifeng saw that this iron box was so thick, and it looked absolutely unclear, and guessed that there was definitely a treasure in it. The Black Ghost also heard the noise, and it was very strange for him to see this box, and he had not noticed it in the medical vault before.

"It doesn't matter if he's a treasure or a ghost, open it first."

Zhang Mazi was anxious, and immediately picked up the box and threw it to the ground. With a snap, the lock on the box cracked, and the noise was very loud. Liu Yifeng hurriedly pulled Zhang Mazi and the black ghost to the side and hid, but the would-be robbers slept so dead that no one heard the sound at all.

"You don't remember what you eat or play, you have said a little bit and a little bit, why can't you remember it."

Liu Yifeng looked at Zhang Mazi with a hatred of iron and steel, and Zhang Mazi could only smile innocently.

"It's over, something happened, it's not a good thing."

The black ghost looked at the contents of the box and said disappointedly, Liu Yifeng also looked at the box after hearing this, this box contained nothing else, it was the Nok virus that the Japanese were developing recently. The culture vessel used to store the virus was shattered, and the virus inside was released at once.

This nook virus is mainly transmitted by the air, and the speed of transmission is very fast, and people within a radius of two kilometers will be infected in less than ten minutes. However, the virus can only spread two kilometers at most, and although it spreads quickly in the air, his lifespan is very short, and he will die on his own after three minutes.

But the only thing that is certain now is that Liu Yifeng and the three of them have been infected with the virus, although this virus will not be transmitted from person to person, and will only exist in a single individual, but his lethality is very high, and now they not only want to save Hu Zhao, but even they themselves are mud bodhisattvas crossing the river, and they are difficult to protect.

"I really want to kick you, when will you be able to get rid of this hairy problem, you weren't like this before, Lao Zhang, why don't you use your brains to do anything now?"

Liu Yifeng scolded Zhang Mazi, Zhang Mazi lowered his head and didn't dare to speak, living like a child who did something wrong. The black ghost smiled and grabbed the angry Liu Yifeng.

"Yifeng, since the virus is here, then there must be an antidote, we are looking for an antidote while looking for tranexamic acid, and we must find the same tonight."

Liu Yifeng saw that the black ghost said this, so he had no choice but to shut up and began to look for medicine. Seeing that Liu Yifeng no longer scolded him, Zhang Mazi slapped himself twice, and began to find medicine seriously.

The hard work paid off, and the Black Ghost found a chest engraved with internal damage in the innermost part of the medical vault. After he pulled the box out, he resolutely saw the four big words "tranexamic acid". In addition to this medicine, Zhang Mazi also took away some medicines for the treatment of other organs in case of emergency.

Now that I have found tranexamic acid, I am about to solve my own problem, where to find antibodies to the virus? This is a medical library, although there are countless drugs, but the antibodies must not be stored here, otherwise the effect of the drugs will be directly lost, and as for the box containing the Nok virus, it is completely a mistake of the Japanese Kou.

The three of them left the medical depot and began to search for the biochemical laboratory of the Woko in the barracks. But to their surprise, the biochemical laboratory of the Japanese is no longer in Hushi Mountain, and it is very likely that it has moved into the county seat.
