Because only the Escort Agency recognized by Zhao Sihai was the real Qihai Escort Agency, which could travel through all seas and be welcomed everywhere.
In the beginning, the Escort Agency was established by Zhao Sihai's eldest apprentice, but its original name was the Qihai Escort Agency.
After all, how could the disciples use their master's esteemed name to title the agency?
After the eldest apprentice sacrificed his life in that beast tide, the Qihai Escort Agency lost its guardian and its business declined day by day, ultimately closing down.
It was only many years later that his descendants reopened the Qihai Escort Agency.
However, they were of meager strength and there was a clear generational break, so naturally the business remained sluggish and deserted.
It was then that Zhao Sihai, who was severely injured at the time, personally wrote four characters and sent them over, which changed the agency's situation.
And those four characters were "Qihai Escort Agency."
