Yunfeng gratefully thanked Gu Nian and Lin Chen again.
"It's just a trivial effort for us to save you, it's not worth mentioning." Lin Chen said: "Speaking of which, why did you leave the shelter and walk around in the ruins outside?"
"That's because I want to find some things left behind by people in the past. Especially this."
As Yunfeng spoke, he took out something from his gray old cloth bag.
The thing was a small piece of sparkling crystal.
"In our shelter, we rely on this energy crystal developed by people in the past to supply energy, so that everything in the shelter can operate normally." Yunfeng said.
When Gu Nian heard this, he looked at Lin Chen.
It cannot be denied that even though this world has become a wasteland planet full of nuclear radiation and scorched earth, some of the technologies here are still much more advanced than the world where Gu Nian and Lin Chen lived.
The three of them walked forward for another ten minutes.
At this time, Yunfeng pointed to the faint light coming from the front and said to Gu Nian and Lin Chen: "The front is our refuge."
Although the light in this passage was very dim, Gu Nian still relied on his good night vision to see that there was a sign on the corner not far ahead that read "Ivy Shelter Welcomes You".
When they followed Yunfeng's footsteps and walked around the corner of the passage, the light became slightly brighter and their field of vision instantly broadened.
This shelter is very large.
There is a very wide square square in the center.
There are many doors on the hand-excavated wall next to it, which should be the residences of the people living in this shelter.
There are more than a dozen people busy in the square.
Yunfeng, Gu Nian, and Lin Chen were seen from a distance, and everyone was walking towards this direction.
"Yunfeng, have you met other humans!" A young man of similar age to Yunfeng asked.
This young man ran the fastest and had already arrived in front of Gu Nian and Lin Chen. While talking to Yunfeng, he looked at Gu Nian and Lin Chen curiously.
"Hey, I met them when I was looking for energy crystals outside. If I hadn't met them, I probably wouldn't have been able to come back today." Yunfeng replied with a smile.
After that, he introduced to Gu Nian and Lin Chen: "This is my good brother, Xiao Ming."
"Hello." Gu Nian and Lin Chen nodded to him together.
At this time, the administrator jointly elected by everyone living in Ivy Shelter also came over.
"Hello, welcome to Ivy Sanctuary. I am the administrator here, Hong Bo."
"We come from a place far, far away. The name of that place is Jiangcheng." Gu Nian replied.
"Jiangcheng? It is indeed a place we have never heard of. You must have traveled a long way, right?" Hong Bo said while looking at Gu Nian and Lin Chen with sympathetic eyes.
"It's not safe outside at all now. You might as well stay in our shelter. It's been a long and dusty journey. You should have a good rest. We'll go to the office to talk first, and we'll arrange a place for you later."
