Two days ago, Yang Shi tried to increase his physical attribute without external means. So, he decided to push his physique to extreme limits.
He forged bracers for arms and a pair of greaves for legs. Each of them was made from concentrated alloy, so their weight is great.
Each of them weighed 300kg. Yang Shi also made thick armor that weighed more than 500kg.
Those pieces of equipment were inscribed with Qi Suppression Spirit Diagram.
With this spirit diagram, the flow of spiritual qi inside Yang Shi's body would be slower than average.
That means, his casting time for techniques also increases. It will become a disadvantage during the life and death battle.
However, using such a method to train the body has obvious effects. After removing those types of equipment, Yang Shi felt that the flow of spiritual qi was much faster than before.
Moreover, his physical capacity and endurance also increased quite a lot in three days.
