In the autumn at the end of November, the night wind is very cool.

That night, there was a burst of heavy rain outside the house, and the sound of raindrops falling down gave Yoko and his group the best camouflage.

Xiao Zhan specially asked Dr. Charles to prepare a single room for him. Lao Zhuang Yangzi and his party secretly put on night clothes and weapons after waiting for the nurse to round the room. The power of the rope, jumped down.

Gu Ruyun and the master Yi Rong named Xie Yushu who came with them this time, carefully cleaned up the ward, using the pillows and quilts to bulge the arc pretending that someone was lying on the bed next to the hospital bed to accompany the family members.

As long as the lights are turned off and the nurses on the night watch do not enter the room to investigate, then they will definitely not be able to find out that the four of them have left the room.

Gu Ruyun looked at Xie Yushu, but was a little curious about the young man in front of him, "Why don't you go with Yangzi and the others."

With one more person and more power, Xie Yushu in front of him knew at a glance that he was also a trainer on weekdays.

Xie Yushu smiled at Gu Ruyun, revealing two pointed little tiger teeth, "My skills are not very good, and I barely do clerical work on weekdays, so I don't want to follow along to cause trouble."

Gu Ruyun's eyes flashed and she nodded to show her understanding, but in fact she didn't quite believe what Xie Yushu said. To be able to come out with Xiao Zhan this time, it could be because of poor skills, so she could only do clerical work reluctantly. the weak scholar? According to the serious attitude between the Wei teachers, this is obviously unlikely.

Since the other party is unwilling to say all of this, Gu Ruyun will naturally not force Xie Yushu.

Sitting in the pitch-black ward, listening to the sound of rain outside the room kept falling, the raindrops fell on the grass, on the leaves, on the ground, and the sound on the glass windows was not at all. It leaked into Gu Ruyun's ears.

...

However, on the other side, the tense rescue operation is in full swing.

The four of Yoko were dressed in black combat uniforms, with a simple luggage behind them, which contained some of the guns and ammunition they brought this time.

These ammunition and guns were taken out of the hospital bathroom by Xie Yushu before.

Guns and ammunition can't pass the security check, but the informants who have been rooted here have a way to get guns and pills. They put these things in the hospital bathroom early, and they can only sneak them when they arrive. Go to the bathroom and bring these things back. The weapons that were sent have been disassembled long ago and have lost their original appearance. If it weren't for Yangzi, who is proficient in this way, Lao Zhuang and a few people would have no choice. All these things were reassembled and sorted out during the war inspection.

The light and soft soles stepped on the road without making any noise, under the cover of heavy rain.

The four of Yoko found the entrance to the secret research institute without much effort.

The base of this secret research institute is not too big. There are more than 100 people in the whole base. These people don't go out at all on weekdays. They only go home every three months to take a few days off.

It is precisely because of this that the entire secret research institute has existed for several years, but very few of the staff at Mary's Hospital know about the existence of the institute, let alone others.
