Why didn't he explode to death?

Jack and Wesley probably didn't expect this either, and reinforcements were already on their way.

Mu Yuan's vision turned black as he watched that person start to install the cannon. This was a simple chasing cannon. However, no matter how simple it was, its power was not inferior at all. When this cannon came crashing down, it would also send Jack and Wesley to heaven.

"Ye tingjun, give them a warning. Is there any way to give them a warning?"

Ye tingjun saw it too. He was anxious too. If Wesley and Jack were to die, they would be killed by such a shot. This would be bad. International relations would be in a mess.
