The location to create the spirit spring had already been decided.
Shi Wu brought the spring egg Gu and went with Man Duo, after making the preparations, he starting using his primeval essence and sent it into the lasting Gu and continuing Gu, before injecting it into the spring egg Gu.
The spring egg Gu floated in the air, absorbing primeval essence as it moved up and down slowly.
For the next eighteen days, Shi Wu slept three hours a day, rushing to eat his meals and settle his excretion. Although it was tough, the effects were showing.
As he continued to inject primeval essence, the spring egg Gu was shining with a brilliant light.
These days, Man Duo had come to inspect again, and upon seeing this, he was overjoyed: "We are almost there. There are mild cracks on the spring egg Gu already, once it breaks, we will succeed. It has been tough on elder Shi Wu."
"Not at all, not at all." Shi Wu refined the Gu while humbly replying.
