Due to Ren Xiaosu's appearance in the rear, the enemy had no choice but to divert a large number of their men to deal with him. That suddenly relieved the pressure on Jin Lan's group, and it was something they could clearly feel.
However, while the enemy thought Ren Xiaosu would force his way into their formation, they were surprised by how Ren Xiaosu remained just outside of their effective attack radius throughout, even though he had rushed towards them aggressively. He was kiting them, pulling them in and then letting go.
Ren Xiaosu was not holding back. He had activated the nanomachines and was crazily cycling them in his body to prevent himself from getting shot. Even if he did get hit, he could immediately use the nanomachines to stop the bullet from causing further damage.
