"Void Bubble".
Lin Feng's eyes lit up. He had searched for astral martial arts for a long time, but none of them satisfied him.
Actually, he also had a self-established rule deep down. The Astral martial arts he needed first excluded defensive martial arts. His undying characteristic was very powerful. At least currently in the Metamorphic Realm, with the undying characteristic, he would almost never encounter any life-threatening danger.
Thus, defensive martial arts were not very useful. He did not need to use Astral Power to protect his life. What was Lin Feng good at?
Without a doubt, it was strength!
In fact, just based on his current physical fitness, be it defense, speed, or strength, it was actually quite strong. However, since he practiced Nonuple Body Tempering and had awakened two strength-related innate abilities, with such a powerful advantage in strength, wouldn't it be a pity if he didn't use it to the fullest?
