The summer wood is thick and the courtyard is deep. Before you know it, the weather is starting to get hot. When the weather is hot, most people will look like a whim, but Xi Yan is not like this, because he still has a lot of things on his hands.

First of all, the robbery and murder case in Shigu Alley involved rebellion, several days have passed since the emperor gave it two months, and Xu Bin, the secretary of the Criminal Department, has already been anxious.

Xi Yan was in the Criminal Department, and he had to make an all-out investigation, Xu Bin wanted to go to the table several times, asking the emperor to temporarily hand over the control power of the internal guard to the Criminal Department, so that the Criminal Department could search in Chongdu City.

But as soon as Xu Bin showed this kind of thought, Xi Yan and the officials of the Criminal Department would desperately stop him.

The reason why the other officials of the Criminal Department blocked it was because they didn't want to cause trouble for themselves, let alone deal with the internal guards, and they didn't want to make the people in the capital panic, besides... If the case is not solved within the time limit, it is Lord Shangshu who suffers anyway, and for them, it is the best state to be able to fish in the yamen.

As for Xi Yan, it was because he knew that a large-scale search would never find out the results, and maybe it would disrupt his plan...... And when it was time for the situation to continue, he absolutely did not want this matter to be exposed.

So during this period of time, Xi Yan basically didn't make much effort in the Criminal Department, allowing his subordinates to look for and bump around like headless flies. The only thing he really focuses on at the moment is water.

The atrium of the Begonia Courtyard is very spacious, the courtyard is paved with blue-black stone slabs smoothly, only a little plantain is planted at the root of the wall, although it is not as beautiful as the backyard, but it is more empty and atmospheric.

But there were only two people standing in this spacious and atmospheric courtyard, one was Xi Yan, and the other was naturally Xi Yun. The strange thing is that in front of Xi Yan, there are sealed porcelain jars on display, these porcelain jars are very large, if they are opened, they are enough for an adult man to squat in. Xi Yun didn't know why, but Xi Yan smiled slightly, and the whole person looked clear.

"Here, it's all alum oil......"

"Such a quantity...... Xi Yun frowned slightly, "This is the alum oil you ordered to be transported over there in Lingjiang a few years ago?" ”

"Yes," Xi Yan bowed his head slightly, raised his eyes to look at the somewhat thick clouds, and said, "This afternoon, these alum oils will be transported to Shuishui first, and when the alum oil arrives in Shuishui, you will personally bring people over." ”

"I will not disgrace my life!" Xi Yun's eyes were firm, he knew how risky it was this time, but he, like Xi Yan, had no other choice at all.

It stands to reason that Xi Yun shouldn't have walked away, but this time it was too important, except for Xi Yun, Xi Yan couldn't rest assured, and only in this way could he rest assured that he could end the matter of water.

Two days later, at sunrise. With the sound of drums on the city tower, the gate of Chongdu had just opened, and more than a dozen horses had stepped out of the city one after another. Although they were arrogant, none of the guards dared to stop them, because the bridles of the horses had already shown the dignity of their masters. Although it was not clear which one it was, the guards all knew that the one who could have this posture must be the supreme and noble person in the inner city.

Yes, the first person is Xi Yun, and those who have been out of the city this time are all henchmen who have followed Xi Yan for many years, but not far from the city, they broke into pieces, and they took off the noble bridles on the horses, and in groups of two or three, they went in the direction of the water. It wasn't until outside the city that they met again.

The water is not far from Chongdu City, and the group quickly whipped up their horses, and they arrived at their destination in only three or five days.

At sunset, the last two people also arrived, and after Xi Yun counted the number of people, more than a dozen people dispersed again, hiding in all corners of the city.

When Xi Yun saw the green alum oil he saw in the Begonia Courtyard that day, the original large porcelain jars had all been replaced with small porcelain bottles that were easy to carry, and the similarity was that the small porcelain bottles were still all sealed.

According to Xi Yan's instructions, Xi Yun first quietly hid around Xi Qing's temporary residence in the city, and then hid after feeling his form.

The thick clouds had already obscured the moon, and in the dark night when he couldn't see his fingers, Xi Yun led fourteen people to the side of the water embankment.

Fifteen people, all dressed in black power suits, removed all the things that could show their identities on their bodies, black cloth masks, and each carrying ten small porcelain vases. In addition to the sword, he also carried a slender and long iron hammer on his back.

At this time, the embankment was half-completed, so the guards on the construction site at night were very lax, and there were only a few soldiers napping on the embankment more than ten miles long, although it would not be discovered at all, but Xi Yun still cautiously left two people to guard on the periphery.

And he himself, with the remaining twelve men, crept to the riverbank without noticing.

The sound of rolling water and night covered all movement, and the twelve men quickly dispersed, carefully avoiding all the guards. Then, on the side of the newly completed embankment, a small hole was dug deep with a thin shovel every few feet, and the depth of the hole continued to the bottom of the embankment. After that, the hole is plugged so that no trace is left as much as possible.

Although the steps were simple, before coming, Xi Yan asked them not to make a sound as much as possible, so although things were not difficult, they were quite demanding to do, and everyone had to slow down their movements.

Everyone is a well-trained and cautious person, and after using up the alum oil in the porcelain vase, they all meticulously put the porcelain vase back into the cloth bag around their waists, leaving absolutely no trace.

After about two hours, there was no alum oil on everyone. Xi Yun looked up at the night, and then led people to retreat, coming and going, leaving no trace.

The next night, when the moon was obscured again, fifteen men came to the embankment again in full gear, repeating the events of the previous night, and after a few nights, the bottom of the embankment was already full of holes.

On the last night, when all the alum oil was exhausted, Xi Yun stared leisurely at the seemingly unharmed causeway, and the heaviness that had been pressing on his heart gradually disappeared until it disappeared without a trace.

As in the previous night, no one found their whereabouts. Xi Yun stood in the courtyard of the temporary residence in the city of Chushui, his heart was indescribably relaxed, and he raised his eyes comfortably to look at the night sky.

Just as Xi Yun was looking at the half-obscured moon comfortably, a huge bird flew out of the air in front of him, and through the hazy moonlight, Xi Yun could clearly see that the bird was covered with gray-brown feathers, the pointed and long beak, and a bamboo tube tied to the slender bird's feet......

Grey stork? Xi Yun stared at it again, and after confirming that it was correct, he was shocked. He remembered that Xi Yan had said that this bird existed, and Xi Yan said that this was a communication bird unique to the Jing family, and there was no semicolon in the world. When he asked why the Jing family used the gray stork instead of the commonly used carrier pigeon to send the message, Xi Yan only said lightly, "lack of heart and eye......

Indeed, with such an eye-catching bird for communication, there is no semicolon in the world except for the Jing family.

Regardless of being tired, the sky was not yet clear, Xi Yun notified everyone to leave for Chongdu immediately, and there was no delay for a moment. Even faster than when he came, three days later, Xi Yun appeared in front of Xi Yan.
