The Mohist technique relies on the power provided by water.

Now that the power output has been cut off by Guo Jia, the mechanism that Tianyun has closed naturally cannot be activated anymore.

What Wu Fan came down to inspect was naturally not the dry cistern, but the large mud pots placed next to the cistern and in the corridor.

The interior of the cloister was dark, and the place where the torches had been placed had been removed.

But now it's getting brighter, and you can barely see through the passage.

Loomingly, the cloister is also densely packed with large clay pots, and there are also a large number of soldiers next to the clay pots.

These clay cans filled with liquid were brought up by Guo Jia's people in advance.

Wu Fan, after carefully inspecting this layer of mud jars full of things, nodded and said to the soldiers on standby on this floor.

"All the officers and soldiers listen, and then enter the first level of alert, always listen to the order, after the military division gives the order, you must react as soon as possible, and there must be no mistakes."

"No!"

Wu Fan checked it layer by layer, and each layer was extremely serious, and he didn't dare to slack off.

It wasn't until he made sure that there was no problem that Wu Fan was relieved to go back to the danger gate.

Just when Wu Fan returned to the Tianyun Pass after all the inspections, Guo Jia, who had been observing the Tianyun Pass, also found the best opportunity.

The Tianyun Pass is higher than the Tianyun Pass, and although you can't see the details of the situation on the Tianyun Pass, you can also check the approximate situation.

What Guo Jia saw was when Chu Zhantian and other players gathered at the head of Tianyun Pass.

At this time, whether it was a player or a soldier, their attention was affected by Li Yang and them.

Guo Jia knew that this was the best time to implement the plan.

"General Wu, the time has come, immediately order the troops to act."

As soon as Wu Fan stepped on the city wall with his front feet, he was seen by Guo Jia, who had just turned his head.

However, Wu Fan not only did not have any complaints, but nodded excitedly.

Wu Fan obeyed Guo Jia's instructions, and did not order the heralds again, but turned around and ran back by himself.

"The generals will listen to the order, the time has come, and immediately start acting."

Wu Fan ran quickly downwards as he yelled at the soldiers at the bottom of the soldiers.

The soldiers were originally ready to go, but now when they heard Wu Fan's order, they reacted as soon as possible.

At the edge of each cistern stood three soldiers.

I saw that they quickly poured the liquid from the mud tank around them into the reservoir.

After pouring the liquid in their hands, the soldiers threw the empty clay canisters out of the gate.

At the same time as the mud pot fell to the ground and made a cracking sound, the soldiers in the 'cloister' also handed the mud pot next to him to the soldiers next to the cistern.

The soldiers at the reservoir, after receiving the clay canisters, began to pour the liquid into the cistern again.

In this way, a perfect cycle is completed.

Of course, it was possible to use Molong's trick to pour the liquid directly into the reservoir through the pipes on the cistern.

However, not all of these traps are made of wood, and the geared heads of the traps are also covered with fine iron.

When the gears collide with each other, sparks are generated.

Out of this consideration, Guo Jia did not use the Mo family's tricks to draw water directly from the reservoir.

Unable to use the mechanical technique, Guo Jia and the others asked the soldiers to carry these clay pots in advance.

Because of the space constraints, these mud pots are not too large and can only be made up for by quantity.

That's why there are now a large number of clay pots on the city walls and inside the 'cloister'.

Of course, there is not only one type of liquid stored in these clay pots.

It's just that there is a very viscous liquid in it, and there are not many of them.

As more liquid was poured into the reservoir, the debris of the mud tank at the bottom of the pass gradually increased.

However, because Li Yang made a loud enough noise outside Tianyun Pass, plus the alliance of players on Tianyun Pass, their attention was on Li Yang's side.

The sound of the mud pot falling to the ground was not noticed by anyone on the Tianyun Gate.

These liquids, along with the internal pipes on both sides of the cliff, quickly flowed towards Tianyun Pass.

Then the liquid that flowed out of the Tianyun Pass flowed out of the channel outlet in the Tianyun Pass.

Originally, these water flows had a designated channel, which flowed directly to the power center in the Tianyun Pass to provide power for the Tianyun mechanism.

But when Guo Jia and the others left Tianyun Pass, they asked Wu Fan to lead people to change these passages, and newly opened new flow channels.

This new flow of water was carved along the edges of the two sides of each 'cloister' and extended to the center.

And, at a certain distance, a small gap will be opened in this channel.

After the liquid flowed out of the channel in the cliff, it flowed along the newly dug channel of Wu Fan and the others towards the middle of Tianyun Pass.

The amount of liquid flowing into the channel gradually increased, and this liquid also flowed through the corridor with the gap in the channel.

The players in Tianyun Pass have always paid attention to Li Yang and the others outside the pass.

Most people don't notice that the liquid is flowing into the gate.

Since it has been a continuous spring rain in the past few days, there is often rainwater flowing into the interior of Tianyun Pass.

Therefore, even if an NPC soldier notices, then with their intelligence, they will not notice anything unusual about these liquids.

And due to the large number of people in Tianyun Pass, some soldiers were soaked with these liquids.

This is also due to the player's curiosity, and basically all players observe the situation outside the Tianyun Pass outside the gate.

If any player can spot these liquids, they will definitely be able to warn them as soon as possible!

However, although the soldiers did not notice anything unusual, they were all attracted by a fragrance.

They are also quite familiar with this aroma.

When they attacked the Tianyun Pass, this aura was permeated in the pass.

But it didn't take long for the things that emitted this fragrance to be taken away by those who were in charge, and they didn't leave anything with them.

It was also because there was this aroma in Tianyun Pass before, so they missed the opportunity to be vigilant again.

Of course, this is also what Guo Jia calculated in advance.

When Guo Jia and the others left Tianyun Pass, they left some things in Tianyun Pass.

These aromas are these things, which are emanated.

Since these ordinary NPC soldiers didn't notice anything unusual, the liquid gradually flowed into the entire Tianyun Pass.

Wu Fan felt that the time was almost up, so he let the soldiers at the top start the operation.

The goal of this top-level is naturally to close the clouds.

Due to the top of Tianyun Pass, the field of vision is clear, and it is full of players.

The vigilance of the player is not comparable to that of NPC soldiers, so Guo Jia did not launch it at the first time.

Now that I feel that the interior is enough, it is natural to take care of the players who are closed, after all, most of the enemy elites are standing on the city walls.

Of course, while pouring liquid into the sky clouds, the bottom did not stop.

All the channels flowing to Tianyun Pass opened at the same time, and the liquid flowing into Tianyun Pass also increased rapidly.

If it is not discovered, I am afraid it will not be long before it can permeate the entire Tianyun Pass.
