_2_ _nd_ _of April._
Friendship Town, under the help of the main camp, had finally finished construction on the city walls. From start to finish, the nomadic tribes didn't notice that a military fortress was secretly built up north of them.
To further increase the defensive strength of Friendship Town, Ouyang Shuo sent Zhou Haichen a letter to order him to start working on the city-protecting river. The city-protecting river would follow that of the main camp’s. West of it would be the Friendship river and east would be the Qiushui river, forming a huge sac and boxing Friendship Town in it.
This way, Friendship Town would be surrounded by water, and using the water camp, they could attack and defend, getting into an undefeatable position. Before he built Friendship Town into an impenetrable fortress, Ouyang Shuo wasn't prepared to contact the nomadic tribes.
