The doctor who opened the door pushed up his glasses and smiled sheepishly.

Lu Yuan waved his hand and quickly went inside, locking the door from the inside.

"Where is she? Take me there right now!"

The doctor nodded quickly and led Lu Yuan inside.

They arrived at a hidden office, which had been set up as a temporary small hospital.

The room was divided into three small cubicles, each containing two people lying in bed with various tubes inserted into their bodies. Behind them was a monitor displaying each person's vital signs.

"How are they?"

Professor Chen sighed and shook his head: "The situation is not good; the hypothermia has relapsed! We are still doing everything we can to save them!"

"Okay, now come with me, I'll take you to a safe place!"

Professor Chen nodded and prepared to pack his things, but Lu Yuan waved his hand and said, "No need to pack. You come in with me right away. I'll just take these devices with me! There will be someone to take care of you inside!"

After saying that, Lu Yuan looked around the room and all the equipment, Professor Chen, and several doctors disappeared from the room.

They arrived at an unfinished hospital tent in the dimensional space, where Zheng Hai and several others had already come over.

"Old Chen!?"

Zheng Hai was immediately surprised when he saw Professor Chen's appearance.

Professor Chen pushed up his glasses and was slightly taken aback when he saw that the person in front of him was Zheng Hai.

"Zheng Hai? What are you doing here? Where is this place?"

After Zheng Hai briefly explained the situation, Professor Chen finally understood where he was. He had heard Chen Zhongzheng talk about it before, but he had never had the chance to.

When he first arrived at this place, he couldn't help but keep looking at the scenery around him.

It felt like a newly built city, bustling with activity everywhere.

Professor Chen couldn't help but sigh, then he remembered his important task and pointed to the people lying on the hospital beds.

"These people are all returning from outside the fortress. They carry important secrets, so we must rescue them!"
