Solved

In the basement hall, a large number of zombie clones were gathered around a sealing stone in the center.

"How is it? Boss, I told you. After my modification, isn't the sealing stone now full of artistic beauty?"

Sandy looked at his masterpiece excitedly with a proud face.

"Unfortunately, I don't have enough time. If I had a few more months to perfect it..."

"Hmm..."

'Is it really beautiful?'?

Fang Heng looked at the sealing stone, feeling a little tired.

At that moment, a large number of zombies gathered around the sealing stone.

The sealing stone was arranged in two circles.

The zombie clones had one hand on the sealing stone in the inner circle, and the other hand on the sealing stone in the outer circle that had just been moved from the sewer.

In short, Fang Heng listened to Sandy's suggestion.
