Facing the threat of the hand grenade, the black man reluctantly opened his mouth.
In the instant the black man opened his mouth, Wang Dadong swiftly shoved the bottom of the grenade into his mouth.
"Careful, it might explode!" Just as the black man was about to move, Wang Dadong quickly said.
This type of grenade explodes when it comes into contact with air; the fuse reacts with air. If the black man can prevent air from entering the fuse, it won't explode.
The black man glared at Wang Dadong with angry eyes, not daring to move or speak.
Wang Dadong noticed a roll of transparent tape on the table and used it to bind the black man's hands and feet.
Though transparent tape can't really hold a Mortal Realm expert, if he dared to forcibly break free, it might very well detonate the grenade.
After finishing all this, Wang Dadong headed back to the female scientist's lab. If someone dares to plot against him, they should be prepared for the consequences.
