Lin Xi demonstrated the Great Strength Bull Fist in front of the two, then explained the key points and corresponding breathing techniques in great detail.
The two had the strength of top special forces, and their learning ability was strong.
In less than half an hour, they had both mastered this fist skill.
However, as Lin Xi mentioned, the fist skill was powerful, and it demanded a lot physically. The two were panting heavily and feeling light-headed by the third round of practice.
Despite that, the effects were obvious, as their physical abilities were visibly enhancing.
The two, feeling like they had discovered a treasure, planned to rest a bit before continuing to practice.
Lin Xi knew well what the two were thinking, so he reminded them, "The fist skill should only be practiced twice a day, once in the morning and once in the evening. Practicing more frequently or more than twice will cause some damage to your bodies."
