Immediately, Tie Zhu started practicing enthusiastically under the guidance of Li Fei.
This technique was divided into nine stages, with the initial stage being the entrance level. Once mastered, one could withstand ordinary sticks and cudgels, and increase one's strength by two to three times, enough to deal with three or four ordinary adults.
In fact, Tie Zhu's physical fitness already met this standard. If he were to receive the boost from the initial stage of the technique, it was estimated that, with his physical condition, he could take on seven or eight people.
Tie Zhu was exceedingly diligent. Having obtained this technique, he treasured it like a priceless gem.
Li Fei also suddenly felt that this technique seemed to have been created especially for him. His physique was extremely compatible with it. After clarifying the key points of the first stage, Li Fei let him practice on his own.
