章 4683: Attacking the enemy on the shore (1)

This iron chain was very scary, but what was even more terrifying was that the thing behind this iron chain was not so easy to pull an iron chain in the river. It required a very brilliant craftsman to command and some ordinary craftsmen to complete it.

Apart from craftsmen, many experts were also required to coordinate with each other. At the same time, they also had to prevent other ships from touching the chains. All of this required time, and only a large force could do this.

Zhao Hai looked at the chain and knocked it with his hand to feel its quality. It was made of high-quality steel.

Zhao Hai nodded. He stepped over the chain and sneaked forward. There was nothing else in front of him. It seemed that the other party had only prepared one chain. However, if Zhao Hai did not notice it, one chain would be enough.
