Jiang Xiaobai was not simply and purely using his iron sword to hack at the bonfire. Each time, he was using different strengths and methods.
But in the end, it was just one move, a simple strike with the sword.
This was one of the basic techniques of swordsmanship. If one wants to achieve great proficiency in swordsmanship, they must start from the basics. Even though Jiang Xiaobai gained his improved swordsmanship from the system, according to the system's rules, any enhancement leads to corresponding experiences and foundations.
With each strike, Jiang Xiaobai had a new realization.
Though the bonfire seemed illusory, he was still able to catch slight shadows. As though it was set up intentionally, after Jiang Xiaobai had hacked it thousands of times, he actually started to get slightly used to this abnormal sensation.
Simultaneously, he astutely noticed that reality and illusion, though they appear different, also share some similarities!
