"We still have to be on guard. If they get the bird gun and use it for research, and find out something, there's no guarantee they won't have other ambitions." Ying Zheng was still wary of Ying Yuan, so he asked Fusu to send people to keep an eye on him.
"What the Emperor said is true. We must be on guard against it."
The fleet rested in Lingnan for a few days, then set out on its return journey, returning to Xianyang on a large ship.
The strong rise of water transportation in recent years has widened the rivers in various parts of Daqin, allowing more large ships to pass through and making the waterways smoother.
Ying Zheng looked at the changes in the Qin Dynasty and felt a lot of emotion in his heart.
On the road, you can see some places building dams and some places digging reservoirs. There is construction everywhere, but there is no numbness on the faces of the people when he was in charge.
Looking at these people again, each of them was full of energy, and none of them looked as skinny as the people he had seen before. It was obvious that they had lived a good life in recent years.
"The Qin Dynasty has changed so much." Ying Zheng sighed.
"Your Majesty, she is a man of great talent and strategy." Gan Luo said with a smile. He also taught Zhao Qingrui for a period of time.

He has been sent by Your Majesty to gather the people to dig a reservoir to store water. If a drought occurs, water will be released from the reservoir. If a flood occurs, the water will be diverted to the reservoir and stored." Wang Jian came over and told Ying Zheng the news that he had asked someone to investigate.
After hearing about the function of the reservoir, Wang Jian was amazed. Why didn’t they think of it at the beginning? This way, there would be no need to worry about droughts and floods.
"Qing Rui is still the one with the idea. This reservoir will be of great use to our Great Qin." Ying Zheng's eyes lit up.
"Not only that, if a large amount of water accumulates here, we can also raise fish here. I believe there are many fishermen who would be willing to do that." Gan Luo looked at the endless reservoir in front of him.
"Raising fish is really a good idea." Ying Zheng praised. If such a large area is used to raise fish, a lot of money can be made.
