Wang Wei looked at the bound Li Jun; he saw the calmness, helplessness, and determination in the latter's eyes. In this short period, he used his [Future Buddha Self] to see thousands of futures and did countless simulations, and the result was the same.
Furthermore, with each passing second, the amount of opportunities he had was diminishing. Di Tian's power was too close to his own, and the latter was on the highest alert.
More importantly, he was determined to make Wang Wei suffer, affecting him psychologically, giving him an edge in this battle.
"I'm waiting," said Di Tian. "And I'm not very patient." He would not give a Dao Overlord enough time in such a dangerous situation. So, as soon as he senses something wrong, Li Jun will die.
Di Tian has even prepared for the unlikely scenario that his mind is frozen or affected in any way possible. If that happens, the runes he placed on Li Jun will automatically activate, killing him.
