The little nurse promised to steal the keys for them, but it was really fast. On the next day, the keys were stolen by the little nurse.

Because the key is placed in the clinic, the doctor did not keep it at home, because there are family members at home, it would be difficult to explain. So he placed it directly in the clinic.

The young nurse is the person who has been in the clinic for the longest time. It is easy to get the keys, and the doctor has never suspected the young nurse.

The doctor's unsuspecting gave the little nurse a chance. The little nurse gave the key to Cao Wenhan, but asked Cao Wenhan to return the key as soon as possible. She was worried that the doctor would find out.

Cao Wenhan got the key and directly found Xi Chen and others, and then they went to the bank.

The bank is still very large, and there are many people inside. They bring the keys to the bankers to see.

When the bankers looked at it, they knew that this was their key. No matter who the person they came, they just had the key.

Xi Chen and others were taken into the bank and then entered the safe storage place. There were many safes inside, and Xi Chen and his friends had numbers on them.

When they came to the safe they were looking for, Xi Chen gave Fang Siyu a look, because they only had keys and no passwords, and they needed to let the bankers leave.

Fang Siyu started chatting with the bankers, and soon the bankers were fascinated by Fang Siyu's chat. The bankers even thought that they could communicate with Fang Siyu at night.

However, Xi Chen and the others have already started to unlock the locks, and the bankers have not paid attention to the situation here, because in the bankers’ eyes, if you have the key, you basically have a password.

If you don't have a password, you only have a key, and you can't open the safe, so they are not very worried.

Not to mention, this safe is really hard to open. Xi Chen has been driving for a long time and it is a little bit short.

Fang Siyu took a look and knew that he needed to do something. Fang Siyu sent the bank's people away and walked over.

The bankers have actually discovered something abnormal now because Xi Chen has not moved for a long time.

The banker followed Fang Siyu and Xi Chen gave Cao Wenhan a look. If the banker was doing something randomly, he would pay first.

Fang Siyu signaled that there was no need. Fang Siyu came over and said, "Are you okay?"

Just as Fang Siyu was talking, she began to enter her password. In fact, Xi Chen had found several passwords, but the last one was missing.

After Fang Siyu came, he actually opened it.

Xi Chen breathed a sigh of relief. Fang Siyu's ability is still strong, but Fang Siyu thinks Xi Chen is not bad either. If Xi Chen had not completed the previous one, she would not have completed these things.

The banker thought it was strange, but when he came over and saw it open, he naturally greeted him with a smile. He didn't want to offend Fang Siyu, but he also wondered if he had a chance.

There was a box in the safe, and the box should be the experimental data that Xi Chen and the others worked hard to find. Xi Chen and others took the box and left immediately.

Fortunately, the bank did not check what the customers were storing, and the Japanese did not have the ability to open the safe in the bank to see what was storing inside, otherwise this thing might have been found by the Japanese long ago.

The doctor is still very smart. If the experimental data is placed here, the Japanese may not be able to guess at all.

After leaving the bank, everyone breathed a sigh of relief, and Cao Wenhan said, "I'll go and send the keys."

Although they took out the items in the safe, Xi Chen and the others did not return the safe, and they still asked to continue using it.

And I just put some things in it, so I continued to keep the safe, otherwise they would have no keys and there would be no way to return them to the young nurse.

Since the experimental data has been taken out, of course, the key must be returned to the young nurse immediately. Cao Wenhan is also worried that the young nurse will be discovered, so it is difficult to explain it at that time.

Xi Chen said: "Go and go back quickly, and tell the little nurse that you are going out to perform the task, do you understand?"

Telling the young nurse Cao Wenhan to go out for tasks is nothing more than not being able to meet the young nurse. After a long time, the young nurse will naturally forget Cao Wenhan.

Moreover, when Cao Wenhan leaves the battlefield, the young nurse will think that Cao Wenhan has died outside.

Cao Wenhan said, "Don't worry, I understand."

Cao Wenhan went to find the young nurse, and Xi Chen and Fang Siyu went back with the experimental data. This thing is too important. If it is lost in their hands, it would be a sin.

Fortunately, when I returned to the room, I was not in danger.

Looking at the box, Fang Siyu said, "Do you want to open it and take a look?"

"Of course, otherwise how can we know what is inside?" Xi Chen said.

They need to check this thing, otherwise it is not the experimental data they are looking for. They are busy working hard and handing it over to Liu Yuhang, and they find that it is not what they need, which is not a joke.

However, before opening the box, Xi Chen said: "Check the box first."

Some boxes have mechanisms. If you do not open the box according to the mechanism, you may touch the mechanism inside and destroy the things in the box.

Xi Chen took the box and checked it. At the end, Xi Chen said, "I'm thinking too much."

I really thought too much, and the doctors came to hide like this, so why bother to make a machine box?

Moreover, the machine box is not so easy to get.

"Stop talking nonsense, open it up quickly." Fang Siyu said to Xi Chen.

Xi Chen opened the box, and there were indeed thick experimental data inside.

But Xi Chen saw it and was a little confused.

It was Japanese, he didn't know Japanese, and there were also formulas and other things. Xi Chen looked up at Fang Siyu.

Fang Siyu looked at Xi Chen and said, "Look at what I do? I can kill people, how can I do the experiment?"

"Although I can't understand it, this thing should be the experimental data that Liu Yuhang wants. If you have any hope for these things, I will contact Liu Yuhang." Xi Chen said.

Fang Siyu said: "Okay, don't worry, it's safe here."

"Okay, I'll hand it over to Liu Yuhang and others earlier, so as not to have too many dreams." Xi Chen said.

After Xi Chen left, he went to find Liu Yuhang, but Liu Yuhang was not at home.

Xi Chen left a clue at Liu Yuhang's doorstep, which was to ask for a meeting.

At this time, Xi Chen asked to meet, which was probably just for the sake of experimental data, so Liu Yuhang would definitely understand.

After doing this, Xi Chen came back, and Cao Wenhan also came back at this time.

The key was returned to the young nurse, and Cao Wenhan also told the young nurse that he might have to leave here and work elsewhere.

The young nurse was a little reluctant, but she was still very rational because the young nurse also hoped that China could win.

The young nurse originally said she would wait for Cao Wenhan, but Cao Wenhan refused.

Cao Wenhan told the young nurse that he might die at any time and told the young nurse not to wait.

Who knew that after saying these words, the young nurse cried so hard, but in the end, Cao Wenhan still left cruelly.

The little nurse will get better, and Cao Wenhan doesn't need to worry, so Cao Wenhan began to ask about the experimental data.

Xi Chen told Cao Wenhan that it should be true and had notified Liu Yuhang and handed it over to Liu Yuhang when the time comes.

Chi Rong also kept paying attention to them. Seeing them coming back, she naturally couldn't help but run over from her side.

Chi Rong was relieved when she heard that they had already obtained the work. They spent a lot of time on this thing.

Of course, I was waiting for Liu Yuhang tonight. Xi Chen knew that Liu Yuhang would definitely come back today, and he was even more anxious about this thing.

Sure enough, at night, Liu Yuhang came over and started asking directly.

Xi Chen gave the thing to Liu Yuhang, and Liu Yuhang picked it up and looked at it and said, "It's it."

Although Liu Yuhang doesn't quite understand what he is studying, he thinks that this one will not be wrong.

"What should I do next?" Xi Chen asked.

Liu Yuhang said: "I will hand over the things to the people in the organization to see the news about the organization."

"Where is the battlefield mission?" Xi Chen asked.

Liu Yuhang looked at the experimental data in his hand and said, "This is the relationship between battlefield missions. We may start entering the battlefield mission soon, and danger may follow."

"It's been ready long ago." Cao Wenhan said.

How is it possible to have no danger in a special battlefield? They are ready and just waiting for this moment.

"Chi Rong, please inform Huang Qiang and let Huang Qiang prepare. We are responsible for figuring out what these things are and tell you when the time comes." Liu Yuhang said to Chi Rong.

"Okay, no problem." Chi Rong said.

After Liu Yuhang packed the things, he said, "Wait for me to hear from you."

"Do you use us to send it to you?" Xi Chen was a little worried. Liu Yuhang is now carrying experimental data, so they are not relieved.

Liu Yuhang thought for a while and said, "Send me back."

This gift refers to secretly protecting, rather than going back together with a big fanfare.

Xi Chen and the others are secretly not worried about being discovered.

"Let's go." Xi Chen said to Cao Wenhan, just the two of them just need to send Liu Yuhang back.

After Liu Yuhang left, Xi Chen and Cao Wenhan followed in the dark. If there was any danger, they would protect Liu Yuhang.

However, Liu Yuhang was just in case, there was actually no danger, otherwise Liu Yuhang would not dare to come to pick up Xi Chen and the others.

Seeing Liu Yuhang coming home safely, Xi Chen and Cao Wenhan turned to leave.

On the way back, Cao Wenhan said: "It seems that we are really going to start this time."

They all said this spy war, it was not just a spy war.

The first half of the spy war should be this experimental data. In Cao Wenhan's opinion, the latter part requires war.

Xi Chen shook his head and said, "It's not that simple. Now we know the experimental data, but it's not what it does. Maybe there are some things in it."
