Princess Ji Xuan left with thousands of people. She was still in a daze. She also took a group of snow Condors with her, but she did not take any ultrasonic flying beasts with her because the snow Condors did not have any nightmare stones.
Gang Yi led 10000 people. Even though he didn't know where their destination was, he at least knew what it was. It was the ruins of the ancient Great Tribulation Temple.
When Princess Ji Xuan took these thousands of people out to sea, she did not even know where they were going. Shen lang gave her ten ships, and they were all large sailboats. Similarly, they did not have the ancient core or any nightmare stone.
Initially, he could have given her a battleship with an internal combustion engine, but he decided against it as the voyage was too long. It was so long that Shen lang and Ji Xuan could not even find it on the map. If she had an internal combustion engine, where would she find the fuel?
