Zhao Hai and the others were standing on the boat. Yu 'er and Ying' er did not come today because they were women. It was not safe for them to always follow the Jade Wyrm around. Moreover, the Jade Wyrm did not want them to work so hard, so it did not let them follow and left them in the Yu Residence.
There were maids in the Yu Residence, so nothing would happen if they stayed in the Yu Residence. Although the boat was small, it could still fit only four people.
Now that the boat was under Zhao Hai's control, the boat sailed forward like an arrow. Zhao Hai controlled the boat while saying to the Jade Wyrm Dragon, " "I say, fatty, how are you feeling? Did you find anything?"
