Crypt Survival: I Can Hear the Beep

【system hint】

【Do you want to get exotic flowers? 】

Staring at the confirmation on the blue screen, Xiaodao left his hand and began to collect it.

About 2 minutes later, the white subtitles appeared on the blue screen.

[Blue Strange Flower +1]

[Red Strange Flower +1]

The moment the flowers disappeared, the light green lawn at the bottom of the feet instantly turned dark green.

Yu Cheng called out the safe house, and after everything was ready, he began to liquidate and expand, making full use of all available resources as much as possible.

The abnormal chickens surrounded Xiaofan, roaring "snoring" non-stop.

"Master, they said they were a little hungry."

After seeing Yu Cheng's "gentle" eyes, the two abnormal chickens completely quieted down.

Yu Cheng nodded and walked into the safe house.

I saw two strange blue and red flowers placed next to the crypt clock in the corner.

Then, Yu Cheng came to the window.

Looking down, I realized that the spiritual fluid ball had grown a little smaller at some point.

Gotta figure out a way to get a few...

Xiaofan came to him in an instant, shook her little tail, and looked at the slender palm sliding up and down the blue screen.

A blue screen appears.

weapons.

Two low-level burrow weapons, two intermediate-level thrusters, a low-level thruster, a bone knife, a pocket knife and a switch knife, the spears had long been abandoned and lay in the far corner of the burrow.

After checking out the supplies, Yu Cheng placed his hand on the print, and the system blue screen was also displayed in front of him.

[System prompt: Do you want to upgrade the safe house? 】

【Three-level safe house】

Yu Cheng looked at the blue screen in front of him, his eyelids twitched slightly and his flesh hurt a little.

If I had known earlier, I would have ordered more supplies from Yu Lingxuan...

【system hint】

【Is it gradually farm? 】

The subtitles continued to appear, and the required supplies slowly appeared above.

Delicate Sand: 10 (16)

Wood Blocks: 50 (150)

Yu Cheng looked at the blue screen and confirmed [Yes].

Immediately afterwards, after seeing that the required materials in the inventory were reduced by the corresponding value, the golden light instantly appeared on the edge of the iron fortress, and the adjacent construction began.

Xiaofan suddenly went to the door of the safe house, and the sound of "lulu" intermittently entered Yu Cheng's ears.
