Bear Heavy Responsibilities, Return from Death, and Eventually Become an Immortal

After seeing that sword strike, I could no longer use the sword when killing enemies in battle. The further I walked on the path of the sword, the smaller I felt. Haha, I once had a great opportunity to make my body become what it is now. Be strong! But after I got the opportunity, not even a day passed before I was kicked into the ground and barely survived. So how do you survive until now? Get beaten!
