Han Sanqian smiled softly: "Don't be happy so early. Although our plan is feasible in theory, in fact there are still some pain points that need to be solved."

"Mr. Han, what other problems do we need to solve?"

"The first problem is the entrance."

"In other words, we need to open an extra secret port."

"The water from the dark mouth will be poured into our underground river from other places without any influence."

In this way, when the river outside is attacked or blown up by the enemy, the flow will not be cut off.

In the underground river, there will still be a steady stream of water entering it.

The old Dragon King nodded: "That's no problem. It's just an extra vent. It's not a troublesome thing."

Han Sanqian nodded: "The second problem is the river embankment."

"After the diversion, what I require is that the width of the river embankment should be at least one to two meters wide."

The Ming River will inevitably be attacked, so the quality of the river embankments needs to be guaranteed, because it is difficult to guarantee how the enemy will bomb the river.

If the central embankment is not strong enough and is destroyed in the explosion, the risk to the underground river will also increase rapidly.

By then, the undercurrent may be discovered, or it may be implicated in the process and destroyed.

Therefore, the stability of the river embankment is also very important.

"The last one is a trap." Han Sanqian said.

"Trap?" The old Dragon King was a little confused. He didn't quite understand what Han Sanqian meant.

"No matter which side of the Ming River's embankment it is, as long as it's on the side close to the Ming River, try to use looser soil. Even when you are digging, you don't need to reinforce the embankment."

"Why."

"When the enemy bombs, try to let them complete the destruction of our Minghe with the minimum effort."

"ah?"

Han Sanqian gave a wry smile: "Isn't this truth very clear? If the Minghe side is too strong, the enemy will have to bombard it several times."

"Even if we do a lot of reinforcements on the Underwater side, we still have to consider time and cost, so it is unlikely that we can withstand many rounds of attacks."

"So my meaning is very clear. In order to ensure the safety of the Dark River side, if the Ming River can be quickly crossed after being attacked, then cross it quickly, so as not to harm or implicate the Dark River side."

For Han Sanqian, Minghe was actually not an important thing from beginning to end. It was more of a bait and a trap. JrNovels.com
