That day, Mi Ziwen had been in charge of supervising the execution of the spies from Great Wei. Great Wei had sent people to raid the execution ground and fell into Mi Ziwen's ambush.
In the battle, many of the weapons used by Mi Ziwen's soldiers were personally forged by Zhou Shu.
It was also then that Zhou Shu's Golden Bell Shield Technique directly broke through from the first level to the sixth level.
The reason for this effect was not because his weapons had completed enough kills but because the situation was different from usual.
Under normal circumstances, the Horse Slaying Saber would give Zhou Shu two years of cultivation.
But at the time, there had been a succession of 20% increases, mixed with the benefit of his cultivation of the technique being doubled. Back then, Zhou Shu had felt that it was somewhat strange.
The series of events that followed almost made him forget about it.
