In the following days, Wang Bin experimented with sand and other materials, discovering he could still gather the sand into a clump and launch it.

This move was powerful but had significant drawbacks. Firstly, his movements were too conspicuous, easily attracting the enemy's attention. Secondly, the time required to gather the sand was too long, and in a battle, opponents wouldn't give him that much time.

Thus, he spent this period continuously refining the technique to overcome its current shortcomings, hoping to unleash its full potential in future confrontations.

During this time, Guan Xiaoyue was quite frustrated. After watching Wang Bin's demonstration, she felt a slight inkling in her mind, but whenever she tried to grasp it, it slipped away.
