Time flew by, and a day and a night had passed.
During this time, Xu Ping'an was working on unlocking his meridians.
At this moment, his three primary meridians were fully penetrated, and even the hidden veins were just a hair's breadth away from being opened.
The medicinal power of the Yin Yang Flower had completely dissipated, and even the Lower Grade Spirit Stones in his hand were already the fourth one.
However, Xu Ping'an did not care; he took out the fifth Lower Grade Spirit Stone and, in one fell swoop, broke through the last bit of his meridians.
Broken through!
Xu Ping'an was thrilled.
Now that the four main meridians were open, it was time to form the Pill Sea.
In his previous life, he had only managed to penetrate three; now in this life, he wanted to see just how vast the Pill Sea formed by four main meridians could be.
"Open for me!" Xu Ping'an bellowed.
