"First of all, I can exclude the Qi Resting Technique." Xiao Shi thought to himself.
The effect of the Qi Resting Technique was mainly to reduce the consumption of Qi Force. The reason why Xiao Shi had consumed a lot of Qi Force was mainly because he had activated too few Qi vortexes.
After he activated more Qi vortexes, the decrease in Qi Force brought about by the Qi Resting Technique was completely enough. There was no need to upgrade it.
Bewildering Shadow Step could also be excluded. Although this movement technique could form an illusion while moving, making it difficult for people to distinguish his true body, it was ultimately lacking in lethality.
Even if he could create more illusions after leveling up, if he did not have enough strength, he could not kill them.
Xiao Shi also felt that there was no need to improve the Nine Vajra Body.
