For these patterns and words painted by Wu Weiyi, others are in the clouds and do not know why. But for Mo Zhai, after all, he has been with Wu Weiyi for a long time, so his general outline immediately appeared in his mind. I saw that he pondered again and again for a while, and suddenly jumped up and said:

"Brother! By what you say, it's so simple. Wonderful! Wonderful! Why didn't Zhai think about it before? ”

In fact, the reason why Wu Weiyi has this concept is also due to a book he read called "The Manuscript of Atlanticus", which has a diving breathing tube as a reference.

Since ancient times, there has been a custom of diving in China, especially for the southerners. But for the device that can dive, it was not until the Song and Ming dynasties. And Wu Weiyi's move was undoubtedly extremely advanced at this time, even Mo Zhai couldn't help but be amazed, let alone others.

Mo Zhai has already understood the principle, and it is naturally easy to make. The skin is changed with animal skin, and then the sap is taken as glue, the process is exquisite, and it is not very difficult to seal it, as for the pipe, it is made of rattan hollowed out and then spliced with reeds on the head, although it is more fragile, and it can not eat too deep water, but it is enough to deal with this kind of small river.

When the group was ready, they immediately set off, because this place was still within the range of the nineteen battalions and eighteen cards of the Kolo Lum, so Wu Duotong led the way, first towards the north, and then suddenly turned to the south, and went around a large circle, and suddenly hidden, and suddenly deliberately revealed, but deceived many of the checkpoints that had been guarded by the chabu soldiers, and finally ran directly to the west.

It was supposed to be less than two days away, but they walked for five days before they reached the river. At the same time, Wu Weiyi has also figured out clearly, it turns out that this river is called Qingshui River, which is the source of the Yuan River. The river is staggered and the undercurrent is turbulent, so if you want to cross the river, you must find a place to relax. And Maya Evil has obviously been prepared for a long time, and some places that are easy to cross have been strictly guarded.

Wu Weiyi and the others leaned down and found a place to take refuge in a small shrub forest by the river. Seeing that the water was slowing down a little, there was also a guard stationed on the opposite side of the riverbank.

As for the other crossing points, they are either in a dark water situation, or there are guards stationed on both sides of the river. Therefore, fortunately, since this side is close to the dense forest, these garrisons have not set up checkpoints on this side, so this is an ideal crossing point.

Wu Weiyi and Wu Duotong first went out separately, and when they returned to their hiding place, Du Yu stepped forward and asked with concern:

"What's going on out there?"

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

"Since the river bank on this side is as flat as a rock, perhaps the guards on the opposite side are too careless, so only guards are set up on the opposite bank."

But he asked worriedly:

"But the river here is wide, and when I wait to cross the river, won't it be easier for the other party to find out? Or...... Let's look for other places? ”

At this time, Wu Weiyi also shook his head slightly, and explained with great difficulty:

"The garrison here has indeed been lax, and the situation elsewhere will only be more difficult. If you go along the river again, it is the Maling River Valley. Smoke could be seen on both sides of the valley, and heavy troops must have been deployed. If we rush there, we are tantamount to throwing ourselves into a net. ”

Wu Duotong thought for a moment and said:

"Why don't you go to the shore in the middle of the night when it's dark, and then dive across the river as planned. Fang Cai Xiao Wang also found that there was a low wood forest behind the checkpoint on the opposite bank. If we can sneak into the dwarf forest before the defenders find out, we can be sure that we will be able to protect us! ”

Mo Zhai was a little uneasy, and said:

"It's not easy to get to the river and dive there, but it's not so easy to get into the forest on the other side. What's more, it is still unknown how many defenders there are on the other side, and if our whereabouts are discovered, even if we enter the forest, it will be extremely dangerous......"

Wu Duotong sighed and said:

"If you don't take a risk, look ahead and look backwards, you will be afraid everywhere, and then you can only cocoon yourself and die here!"

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

"Indeed, there is no other way. Then everyone get ready, and we'll cross the river tonight! ”

Hearing Wu Weiyi say this, the others naturally had no opinion. After Mo Zhai stepped back, he tinkered with the diving device while explaining to everyone how to use it. He tried it on everyone and repeatedly made sure that there was no air leakage in the skin and no blockage in the pipes, which was a relief.

Mo Zhai then found some cork, dug holes, and put them on top of the pipe of the diving device so that the pipe could float through a small opening.

It's also strange to say that Yang Asha only sat very quietly on the side, and she was stupidly stunned. I don't know why, right now, her heart is full of Mo Zhai's figure, and she doesn't care much about the things around her.

But gradually, I don't know whether it was intentional or unintentional, her eyes were soon attracted by the strange diving equipment, and her curiosity was aroused again, and she kept asking Mo Zhai this and that. And Mo Zhai didn't seem irritable, and only patiently explained to her one by one......

At this time, Wu Zheduo, who had nothing to do on the side, turned his head again and looked in the direction of Kororum, his expression was very gloomy. Although Wu Duotong was busy on the side, he was also aware of it, and wanted to come forward to comfort him, but he didn't know where to start.

Wu Zheduo suddenly spoke:

"Brother Wang...... We're going to get revenge, yes or no? ”

Wu Duo was sad and angry in his heart, but he only nodded fiercely and responded:

"Hmmm......"

Maybe it was innate, Wu Zheduo seemed to have a calmness that didn't match his age, and he could only hear him say lightly:

"If Brother Wang can not forget, it is the best. Brother Wang, I am only worried that after you have only found a safe place at that time, you will be as reluctant as you did a few years ago, and you will forget all about revenge......"

When Wu Duotong heard this, he couldn't help but be full of shame again, and said sharply:

"There is no such possibility! Ay...... Brother Wang is also useless to talk about it now, and my brother is looking at it! ”

Wu Zheduo was noncommittal, and Wu Weiyi heard such a conversation between the two of them, and he sighed secretly in his heart. I really don't know how to resolve Wu Zheduo's age, but he is burdened with such a grudge?

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, but only ate some fresh fish caught from bamboo baskets and drank some river water.

Stay until the dead night, the sky is cloudless, but with this night, it is extremely unfavorable to Wu Weiyi and them. Seeing this round of bright moon in the sky, the surrounding stars lost their light. This kind of light is bound to cause some trouble for their actions.

Wu Weiyi walked in the front, Du Yu followed, Wu Duotong held Wu Zheduo's hand, Mo Zhai led Yang Asha to walk in the middle, and Xu Yu and Bai Yi were responsible for breaking off.

Wu Weiyi carefully observed the movement on the other side of the river, except for the two bonfires, which were conspicuous, other dark places also loomed as if there were people, so at this time, you must not take it lightly.

Then, Wu Weiyi and the others each put on their diving utensils, and with a pipe in their mouths, they walked slowly into the water.

In order to avoid the sound of water, everyone's movements are extremely slow. After a while, everyone quietly dived into the water, because there were diving probes, so everyone could stay in the water for a long time.

Breathing along the pipe, and always being cautious, although the river is not wide, they also wasted nearly a stick of incense before they touched the other side.

As soon as they arrived at the opposite shore, everyone took off the diving equipment, quietly put it into a cloth bag, and carried it on their backs. Wu Weiyi listened to the movement again, beckoned, and walked along the periphery of the sentry post towards the dense forest.

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

"Who?!"

Everyone was shocked when they heard this, and they couldn't help but stop all of a sudden.
