Chapter 167 - Checking the technique 

Sometime later, Sam finished his teaming. He was panting at this moment. Jeni, at this time, went toward him and gave him an energy drink. Sam took the energy drink and gulped it down. At this time, all of his friends were standing beside him. 

"Bro, that was a really intense fight. Just keeping up with those two robots is really very difficult. Also, you don't even use any other technique except your sword technique. If it was me, I don't think I would be able to fight those two robots at the same time." Tony said to him. Sam just smiled at him. 

"Did you increase the power of these robots earlier?" Elena asked him. Sam gets up from the ground. He then said," Yes, I will increase the power up to intermediate D-grade."
