After the group returned to Huafu, it was already late, and everyone went back to rest separately.

Early the next morning, Han Xuening and Hua Zi had just gone downstairs, and Wei Yunxuan and Mr. Wen were already discussing things in the courtyard.

Han Xuening and Hua Zi walked over, and Hua Zi asked, "Lord Wang, what are you talking about with Mr. Wen so early?" ”

"Yesterday in the cave, we were discussing how to deal with those strange fish in the water!" Mr. Wen smiled and said, "You guys should also discuss it together!" ”

Wei Yunxuan said that after breakfast, everyone discussed together.

After breakfast, Wei Yunxuan called everyone to gather and began to discuss what he had seen in the cave yesterday in the room on the ground floor.

Bai Zijun said: "This cave is indeed very dangerous, if it wasn't for Miss Xue Ning's early reminder yesterday, everyone was poisoned by the methane, I don't know what would have happened?" I don't think it's time for us to go to the cave! ”

Bai Zijun is right, but they agreed to Liang Gang's matter, can't they just give up when they encounter a little setback?

Han Xuening said: "Brother Zijun, we have already promised the Lord of Liang Zhai about the matter of going to the secret passage to explore, besides, last time in Jufeng Building, everyone ate the meal prepared by the Lord of Liang Village. Now that we have encountered a little difficulty, we said that we will not go in the future, what will the owner of Liang Zhai think? Also, we will be thought by others that we are people who are greedy for life and afraid of death. ”

Wei Yunxuan also said: "Miss Xue Ning is right, we promised the Lord of Liang Zhai what we promised, and we can't break our promises." Today, let's get together and discuss if there is any countermeasure? ”

After Wei Yunxuan finished speaking, everyone began to think of a countermeasure.

Now, how did you cross that underground river? If you can cross the underground river safely, you won't be attacked by those strange fish.

After thinking for a while, Mr. Wen said, "There is a way to cross the river." ”

"Mr. Wen, tell me quickly, what is the method?" Wei Yunxuan hurriedly asked.

Mr. Wen continued, "Cross the underground river, and we can make a small boat to pass on the underground river in the secret passage." In this way, with the wooden bottom of the boat in the middle, those strange fish under the water cannot attack us. ”

After Mr. Wen finished speaking, everyone thought about it, and it was indeed the case.

Wei Yunxuan said: "Mr. Wen is right, using a wooden boat is indeed a good way. ”

However, after Wei Yunxuan finished speaking, Hua Zi said again: "Lord Wang! The underground river is only half a meter deep at most, and many of us are standing in small boats, and the draft of the boat must be more than half a meter. When the time comes, it will go directly to the bottom of the river, how can this boat row? There are a lot of hard stones at the bottom of the river, and it is easy to break the boat. Those strange fish may attack us. ”

Huazi is right, this is indeed a problem.

Besides, Wu Tong is burly, he stands alone on the boat, it is estimated that the boat can touch the stones underneath, and the method of crossing the river directly with a wooden boat does not seem to work.

"Think about it, is there a better way?" At this time, Wei Yunxuan asked everyone again.

A group of people discussed for a morning, but they didn't come up with a good idea.

In the afternoon, after lunch, Wei Yunxuan originally wanted to gather everyone together to continue to discuss how to cross the underground river in the secret passage.

Han Xuening said that let everyone think slowly after going back, it is difficult for so many people to come up with a good way together.

Wei Yunxuan thought about it, and he was right, so he simply went back to the room in the afternoon to think about it.

However, Huazi couldn't stay and pestered Han Xuening to go shopping on the street and talk about the matter, so she left it with Wang Ye and Mr. Wen.

Han Xuening had no choice but to accompany her to go shopping, and Xiao Dong also went with her.

On the street, Han Xuening saw a fish vendor using a wooden block with an oval-shaped curved blade to remove the scales from the fish.

The wooden blocks are densely packed with small oval blades, which is a simple way to scale the fish.

The fishmonger used a wooden block to go back and forth on the fish, and the scales on the fish fell off.

Han Xuening suddenly thought of a good idea.

She said to Huazi, "Sister! My sister has thought of a good solution! ”

Huazi was puzzled, "Sister! What is the method? ”

"Look at the fish-killing dealer, how quickly he scales the fish!" Han Xuening pointed to the fishmonger who was descaling a carp and said.

Hua Zi carefully watched how the fishmonger removed the scales from the fish, and after looking at it for a while, she said, "Sister! I could see clearly that he had removed the scales from the fish with a tool with a round blade from that wooden block! ”

"That's right! We can design such a tool to catch all the strange fish in the underground river! Han Xuening said with a smile.

Hua Zi suddenly understood what Han Xuening meant, and said happily: "Sister is right, let's use such a tool to keep stirring in the mud in the water, so that those strange fish will kill each other." ”

"That's right! And, in order to prevent accidents, we can put some long planks on both sides of the underground river, so that the underground river is blocked under the planks. These strange fish can't get up either. Han Xuening continued.

"Sister! Let's go back and tell the prince about this method! Hua Zi was very excited, and hurriedly pulled Han Xuening and said.

Han Xuening said: "Sister! Don't be in a hurry, let's go back after a while, and we won't be in a hurry! ”

Huazi is an anxious child, so she has to pull Han Xuening back together.

Han Xuening had no choice but to follow Huazi back to Huafu first.

The two went directly to Wei Yunxuan and Mr. Wen's room, and Hua Zi knocked on the door.

Mr. Wen's voice came from inside, "Which brother is it?" ”

Mr. Wen thought it was Bai Zijun and Ma roughly them.

"Mr. Wen, it's me, open the door!" Huazi shouted outside the door.

"It's a flower girl, right? Are you here to find the Wutong brothers? Mr. Wen said inside, slowly opening the door.

He saw Han Xuening and Huazi standing at the door, Han Xuening looked inside, and Wei Yunxuan was sitting inside thinking about things.

I guess I'm still thinking about how to cross the underground river.

"I'm not here to find Brother Wutong, I'm here to find you!" Huazi said with a smile.

"Looking for us? What's the matter? Mr. Wen was puzzled.

Huazi laughed, "Of course there's something, it's about how to cross that underground river." ”

Wei Yunxuan, who was in the room, also heard the two people talking outside, and asked Han Xuening and Hua Zi to come in.

The two entered the room, and after Han Xuening explained the plan of using the principle of the fish scale tool to eliminate the strange fish in the underground river, Wei Yunxuan said that this was indeed a good way.

Han Xuening also said that a layer of iron-clad wooden planks can be used to make baffles and partitions for underground rivers, so that strange fish in an area can be quickly eliminated.

Wei Yunxuan didn't expect Han Xuening to come up with such a wonderful method, and asked her how she came up with it?

Han Xuening said that she went to the street with Huazi just now, and saw that the vendor who bought fish was killing fish and removing fish scales, so she thought of this method.
