At the moment the Earth Evil Flask was completed, Zhang Yu's face turned slightly pale, and he felt a sharp pain in his chest.
Zhang Yu shook his head helplessly, thinking to himself: "Did I get hurt during the process of handling the Earth Evil Qi?"
He understood in his heart that, on one hand, he still lacked cultivation and experience in dealing with Earth Evil Qi, and on the other hand, the laboratory equipment was too rudimentary.
Even though Zhang Yu was careful enough, he still got a few traces of Earth Evil Qi into his body.
However, this was also within Zhang Yu's expectations.
"Fortunately, I was cautious enough. This level of infection can be endured after a few days of rest."
"The remaining fee for renting a high-level laboratory can be spent on the simulation laboratory in the Spirit Realm over the next few days, to practice artifact refining more."
