The First Gate instruction was to gather the energy from nature into his Dantian, but his Mana Whirlpool was full of energy that his Dantian needed. Tang Shaoyang had an idea of drawing the energy from his Mana Whirlpool into his Dantian. He followed the idea, connecting his Mana Whirlpool to his Dantian.
The empty Dantian absorbed the energy, and he started to feel the warmth on his belly in the following few seconds. But then he realized something bad when his Dantian absorbed too much mana. His Dantian did not expand as he thought it would. It remained the same size, and it started to crack with how much mana it absorbed.
Tang Shaoyang immediately cut the connection between his Mana Whirlpool and Dantian. He did not know what would happen if his Dantian exploded. The Nine Heavenly Gates Scripture also did not mention what would happen if his Dantian exploded, but an explosion inside his body was not something he wanted for sure.
