Construction of the Underground Villa Completed

Howard cleared a flat area next to his tent. "Construct the 'Mobile Underground Villa'!"

"Ding! You have used 50,000 points of stone, 20,000 points of steel, and 3,000 points of supplies!"

"Ding! The underground villa is under construction…"

Howard felt a slight vibration from beneath the ground.

However, the tremor was so mild that only someone as sensitive as him could perceive it.

People playing games and watching videos in the shade of trees nearby were completely unaware.

A few minutes later, the system sent another notification: "Ding! The construction of the underground villa is complete! You can use the villa key to enter the underground villa within a radius of three kilometers!"

Is it really done?!

Howard led the girls into a large tent, where they crowded together and then closed the tent door.

"Hehe!" Helen felt a strong sense of security being so close to others and couldn't help but laugh happily.
