As he spoke, he placed a small bottle of blue liquid into a tiny alloy box and then closed the lid.
"OK, this box can only be opened by entering the correct password. If the wrong password is input once, it will automatically explode, destroying everything inside," he said.
He opened a secret gate the size of a wall, revealing a large shelf with more than a dozen levels, each holding several small alloy boxes.
All of those contained the various perverted drugs he had developed...
Xu Yao asked uneasily, "All these boxes, they all need a password to open?"
"Of course." Tao Hua put the box in an inconspicuous corner and then closed the secret gate.
When the door shut, it merged seamlessly with the wall.
At a glance, it was just a wall; nobody would guess that there was a different world behind it.
"Are all the passwords the same?"
"Do you think that's possible? If they were all the same, once someone got hold of the passwords, wouldn't all my drugs get stolen?" he retorted.
