"Now I don't have to care about my health or qi to get exhausted hehe then let's start the second trial!" He laughed while his eyes became slightly cold, to prepare himself what was about to come.
He took a deep breath and took out sword of darkness from system storage. This sword is also temporary available only for one week.
However as we know that he only need this sword for only one week.
After he took out the sword from his system storage, he felt that he could easily slaughter the entire heaven and earth.
"This feeling of invincible is really great." He didn't feel anything when we talk about his qi however since the system had said, then it's not false.
He attacked randomly using his qi and find out that he didn't consumed anything.
