Cave Survival × Sign-in System × Space × Cute Pets × No CP When she woke up, Ning Yao found herself involved in a cruel cave survival game.
Here, millions of participants are forced to dig, fight, and survive in endless caves. Each person can only dig four times a day. Exceeding the limit will trigger a catacomb riot. Each cave is full of unknowns - it may be a resource point, a monster lair, or a deadly trap.
But Ning Yao has awakened a sign-in system that is unique to her!
On the first day, she signed in to get a military shovel, and with the help of pet cat Qiuqiu, she killed the crystallized lizard, triggering the first kill announcement in the entire region!
Immediately afterwards, she signed in to get a portable space, which included a spiritual field, a spiritual spring, a cabin, and could be upgraded and expanded!
After signing in again, her sign-in reward was actually...
Not only that, her pet cat Qiuqiu actually began to awaken special abilities after swallowing the monster crystal core!
While others were still worrying about food and water, Ning Yao had already planted spiritual plants, drank spiritual springs, and even started to build her own cave safe house!
But the danger has just begun——
The monsters deep in the cave are evolving...
Other survivors are watching with eager eyes...
The secrets of the sign-in system gradually surfaced...
In this dangerous underground world, can Ning Yao rely on the sign-in system to live a wonderful life?
