In a one-on-one battle, none of these enemies were Tang Zhen's match.
The explosive increase in strength and speed caused Tang Zhen to become confident and not afraid of battle.
However, these enemies had guns in their hands, which made him very afraid. If it was not necessary, he would never take these killing weapons head-on, as it was equivalent to seeking death.
A body made of flesh and blood could not withstand steel. This mortal thought still affected Tang Zhen. However, he did not know that Tang Zhen had already reached a level that a mortal could not imagine.
Even the most terrifying nuclear weapon would not be able to cause him any harm, let alone ordinary metal bullets.
In a situation where he had sealed off his original memories, such thoughts were normal. Courage was important in battle, but it also required him to judge the situation.
