Others were confused about the patterns and words that Wu Weiyi drew. But for Mo Di, after all, he had been with Wu Weiyi for a long time, so his general outline immediately emerged in his mind. He thought about it again for a while, and suddenly jumped up and said:

"Brother! After you said this, this thing is so simple. Very wonderful! Very wonderful! Why did Zhai never think about it before?"

In fact, the reason why Wu Weiyi had this concept was due to a book called "Atlanticus Manuscripts" he had read, and there was a diving breathing pipe for reference.

Since ancient times, China has had a custom of diving, especially among the southerners. However, the devices that can dive were not available until the Song and Ming dynasties. Wu Weiyi's move was undoubtedly extremely advanced at this time. Even Mo Di couldn't help but be amazed, let alone others.

Since Mo Zhai understood the principle, it is naturally easy to make. The skin was changed with animal skin and then the sap was taken into glue. The process was so sophisticated that it was not difficult to seal it. As for the pipe, it was made of hollowed out of the rattan and spliced ​​with reeds on the head. Although it was relatively fragile and could not eat too deep water, it was enough to deal with such a small river.

The group was ready and immediately set off. Because it was still within the 18th junction of the Ninth Camp of Krome, Wu Dutong led the way, first heading to the north, then suddenly turned to the south, circled a lot, then suddenly became hidden, and suddenly showed his traces, and deceived many checkpoints that had been guarded by the soldiers of the Cha army, and finally rushed directly to the west.

It was only five days before they walked to the riverside in less than two days, but Wu Weiyi had already figured it out clearly that the river was called Qingshui River, which was the source of the Yuan River. The river was staggered and surging, and the undercurrent was also surging. Therefore, if you want to cross the river, you must find a place to ease. Mo Yaxie was obviously prepared for a long time, and some places that were easy to cross were already strictly guarded.

Wu Weiyi and the others bent down and found a place to avoid a small guan forest by the river. Seeing that the water was slowing down, there was also a guard standing opposite the river bank.

As for other crossings, they were either in a dark and urgent situation, or there were guards on both sides of the shore. Therefore, fortunately, since this side was next to the dense forest, these guards had never set up a checkpoint on this side, so this place was considered a relatively ideal crossing.

Wu Weiyi and Wu Duo first inspected outside separately. When they returned to their hiding place, Du Yu stepped forward and asked with concern:

"What's the situation outside?"

Wu Duo sat down next to his brother Wu Zheduo and said:

"Because the river bank here is flat, perhaps because the guards on the opposite side are too careless, only guards are set up on the other side."

Xu Wu asked with concern:

"But the river here is wide, so when I wait to cross the river, wouldn't it be easier for the other party to discover it? Otherwise... let's look for other places to cross?"

At this time, Wu Weiyi shook his head slightly and explained in a rather embarrassing way:

"The preservation here is indeed lax, and the situation elsewhere will only be more difficult. If you walk along the river, it will be the Maling Valley. There are smoke from cooking vaguely on both sides of that valley, and it must have been heavily troops. We will go there rashly, which is like throwing ourselves into the trap."

Wu Duotong thought for a moment and said:

"Why don't you go to the shore when it's dark late at night and dive across the river according to your plan. Just now, Xiao Wang also discovered that there was a short wood forest behind the checkpoint on the opposite bank. If he could sneak into the short wood forest before the defenders discovered it, the materials would be able to keep us in full!"

But Mo Zhai was a little worried and said:

"It is not difficult to go to the river quietly and dive again, but it is not so easy to enter the forest opposite. Besides, how many troops there are on the other side are still unknown. If we are found, even if we enter the forest, it will be extremely dangerous..."

Wu Duotong sighed and said:

"If you don't take a risk and look forward to it, you will be afraid of it everywhere, and then you will be able to tie yourself up and die of trapping here!"

Wu Weiyi rubbed his index finger with his thumb, pondered for a moment, then looked up and said:

"It's true, there's no other way. Then everyone will prepare and we will cross the river tonight!"

After hearing Wu Weiyi say this, the others naturally lost their opinions. After Mo Zhai stepped down, he tinkered with the diving device and told everyone how to use this thing. He tried it on to each person and repeatedly confirmed that there was no leakage in the skin and the pipes were not blocked. This was to let go.

Then Mo Zhai found some cork, digging holes, and put them on the top of the submersible device pipeline so that a small opening could be made.

It was strange that Yang Asha sat alone on the side quietly, and she was stunned for a moment. For some reason, her heart was filled with Mo Zhai's figure and she didn't care much about the things around her.

But gradually, whether intentionally or unintentionally, her eyes were soon attracted by the strange diving device. Her curiosity was aroused again, and she kept asking Mo Zhai about this and that. Mo Zhai didn't seem irritable, and just patiently explained to her one by one...

At this time, Wu Zheduo, who was fine, turned around and looked at the direction of Krom, with a very sad expression. Although Wu Duotong was busy, he also noticed it. He wanted to come forward to comfort him, but he didn't know where to start.

Wu Zheduo suddenly spoke:

"Brother Wang...we will definitely take revenge, right?"

Wu Duotong was sad and angry, but he nodded fiercely and responded:

"Um……"

Perhaps it was born with me, Wu Zheduo seemed to have a calmness that was not matched by his age, and he could only hear him say lightly:

"If Brother Wang can never forget it, it will be the best. I am only worried that after you find only a safe place, you will be as peaceful as you did a few years ago, and you will forget all the revenge..."

When Wu Duotong heard this, he couldn't help but feel embarrassed again and said in a verbal manner:

"There is no such possibility! Alas... Brother Wang is not helpful now, just look at it!"

Wu Zheduo refused to comment. Wu Weiyi sighed in his heart when he heard the conversation between the two of them. He really didn't know how to resolve the relationship between Wu Zheduo and his age, but he was carrying such grudges.

Next, everyone had to wait for the night to come. In order to avoid being discovered by the guards on the other side, everyone did not dare to make a fire. They only ate some fresh fish salvaged with bamboo baskets, and drank some river water and barely dealt with it.

When it was silent, the sky was cloudless, but with this night, it was extremely unfavorable to Wu Weiyi and the others. Seeing this bright moon in the sky, the surrounding stars lost their light. Such light would inevitably bring some trouble to their actions.

Wu Weiyi walked in the front, Du Yu followed closely behind, Wu Duotong held Wu Zheduo's hand, Mo Di took Yang Asha and walked in the middle, Xu Ju and Bai Yi were responsible for breaking the rear.

Wu Weiyi carefully observed the movements on the other side. Except for the two bonfires that were particularly conspicuous, other dark places also seemed to be vaguely visible, so you must not take it lightly at this time.

Then, Wu Weiyi and the others put on diving objects, held pipes in their mouths, and walked slowly into the water.

In order to avoid making a sound of water, everyone's movements were very slow. After a while, everyone quietly dived into the water. Because there were objects with diving probes, everyone could stay in the water for a long time.

Breathing along the pipes, and being cautious, although the river channel is not wide, they have been wasting nearly a stick of incense before they can touch the other side.

As soon as they arrived on the other side, everyone took off the diving device, quietly put it into a cloth bag, and each carried it on their backs. Wu Weiyi listened to the movement again, waved his hand, and walked around the periphery of the checkpoint and touched the dense forest.

Seeing that everyone was about to enter the short woods, I couldn't help but feel a little excited, but unexpectedly someone suddenly shouted behind me:

"Who?!"

Everyone was shocked when they heard this sound and couldn't help but stop.
Chapter completed!
