After more than an hour of busyness, Xiao Yao finally helped the sorceress straighten out the meridians and residual true qi in her body, and the rest could only slowly recover.

Bid farewell to Li Song's family for the time being, and then took the crystal stone used for positioning, no longer delaying time, and walked directly towards the depths of the cave in a dark river.

Xiao Yao chose the bamboo building where he lived before as the place to enter the dark river, and Yi Feng took himself from the dark river into the sinkhole where the watchtower was located, so it is very likely that this place is connected to the dark river inside the watchtower.

While walking into the crystal stone into the true qi, constantly feeling their position, while carefully paying attention to the changes in the surrounding environment, the karst cave of Miao Jiang is a unique topographical feature here, so even if the imperial army surrounded the Phoenix Mountain, it is difficult to attack the watchtower, because it is impossible to pass through the complex underground cave system to completely cut off the connection between the watchtower and the outside world.

Miao Xinjiang is generally mountainous, here are full of mountains, it is the biggest obstacle to the battle of the large corps, the high-speed heavy cavalry can not be deployed here at all, and the heavy infantry here basically has no actual combat value, so the light cavalry and the fast mobile light infantry have become the first choice of various tribes in Miao Xinjiang.

First of all, such an army style is very cheap to implement, and all tribes can afford to equip it, and secondly, this kind of soldier may be a farmer, a hunter, or a sergeant in wartime, which has become a common way of combining military and civilian in Miaojiang.

In fact, there is no way to do this, Miao Jiang is generally short of food, and it is impossible to support a large number of troops alone. In the case of a relatively insufficient army, how to escape has become a common concern of all tribes in Miaojiang.

Therefore, the use of underground karst caves and underground rivers has become the best way for many tribes to escape, so that the map of underground caves and dark rivers has become the most critical information.

Xiao Yao now has a map of the underground caves and dark rivers in the area near Phoenix Mountain, but if Li Zhen also brings a copy to Xizhou, it will be equivalent to Peng's Tusi also having a map of Phoenix Mountain in his hand.

In fact, Xiao Yao still didn't know that Peng Shan and the others had used this strange map to secretly dig up the nine totems of the Jiuli tribe from the underground palace of the Witch God Temple.

Continuing along the cave where the dark river is located, passing through several completely different caves, and diving in several dark rivers, after about an hour, finally arrived at a huge underground dark river convergence place.

Xiao Yao only discovered at this time that not only the huge karst cave under the Phoenix Ancient Tree on the top of Phoenix Mountain was connected to here, but also the karst cave near the beast's cave was connected to here, and the dark rivers were connected to each other, and the main dark rivers all converged here.

It is estimated that this is an aquifer, and the watchtower of the witch temple is directly above it.

This huge cave is surrounded by many streams that converge here, and there are also many caves that branch out to various places.

The annular waterway of the watchtower is to artificially change the direction of several dark rivers that flow into this cave, so that the dark river forms a water circulation system in the lower part of the watchtower, to meet the water demand of the watchtower, and at the same time seals the karst cave under the watchtower with the dark river, if you want to enter the watchtower through the circular waterway of guò, you must dive over.

This section of the waterway is three miles long, so it takes a long time to dive, and the average person simply can't hold his breath underwater for so long, so it is almost equivalent to cutting off the possibility of entering the watchtower from such a circular waterway.

Xiao Yao naturally knew this, and walked along the perimeter of the underground karst cave to measure the vertical and horizontal distance between the underground karst cave and the annular waterway, and finally estimated the distance and time he needed to dive according to these results.

On the one hand, it is ensured that the annular waterway can leave an escape route for people trapped in the watchtower, but it is necessary to use the sluice to control the circular waterway, and on the other hand, it also fully guarantees the safety under the watchtower.

With the sluice open, it is difficult for someone to enter the watchtower from such a route.

Now, Xiao Yao has no other choice, this is the only way he can enter the watchtower.

Moreover, Xiao Yao found that the reason why the crystal stone in his hand could be used for positioning was because someone had buried a lot of special spars in the main dark rivers and karst caves in advance, and these spars were made of the same crystal material, and they were hidden in some relatively hidden places.

If it weren't for Xiao Yao's ability to output the same type of True Qi, there would be no way to discover this problem at all.

Xiao Yao tried to get close to a few spars, and found that although the true qi in them was not full, it was not that it had not been replenished for a long time, but it was obvious that there was a half-step transformation realm master who would replenish the true qi of these specific crystals every one or two years.

No one in the Ghost Fang tribe has entered the half-step transformation realm, so there is no one who can replenish the true qi of this spar, otherwise their own spars will not all run out of true qi.

If you think about it this way, you can only be a person from the Witch Temple.

Obviously, there are also the same spars as Xiao Yao inside the Witch God Temple, and they are also familiar with the underground dark river system under this Phoenix Mountain.

The Witch God Temple knew this, so what about the other forces in Miao Jiang?

For example, the people of the Wei family and the Wu family, who were separated from the ghost Hou lineage, if they also had the same positioning spar as Xiao Yao, then they could also come here in the same way, and even cut off the escape route reserved by the Witch God Temple.

It seems that there has always been discord between the Witch God Temple and the Ghost Dao, Xiao Yao feels that the people of the Wei family and the Wu family do not have any respect for the Witch God Temple at all, both of them are under the guise of a divine stick, and now the Witch God Temple is better mixed, and the other two are more miserable, if someone colludes with external forces, such as the Wei family secretly unites the Wuliu faction.

If that's the case, the Witch Temple is really dangerous.

Individually, the spiritual power is incomparably huge, and the Witch Temple is the spiritual support of the various tribes in Miaojiang, which is not only the core of the belief in Miaojiang Witch Gu, but also the main force of the Miaojiang Wizard System, once the Witch Temple is breached, there will be various problems in the divine power of the various tribes in Miaojiang, then this will undoubtedly become a precursor to the collapse of Miaojiang.

This is also the main reason why Xiao Yao came to Phoenix Mountain this time, that is, to ask the Wushen Temple to play their role as spiritual leaders among the various tribes in Miaojiang, instead of being silent about the war in Miaojiang.

Before, the Witch Temple did not express its position, that was because of the war within Miaojiang, they had to remain neutral, and now that the imperial army is about to enter Miaojiang, it is even possible that the current Xizhou City has been surrounded by the imperial army, and the Witch Temple must stand up and speak at this time.

Xiao Yao didn't want to participate in the struggle for Miaojiang's divine power, but whether it was the Witch and Ghost Conference or the later Phoenix Mountain Rebellion, it showed that Miaojiang's forces were secretly reshuffling.

And now that the army of the imperial court is in the city, if there is any internal competition with each other, then there will be no more Zài in Miaojiang, and there is still any divine power to talk about.

The Witch God Temple actually closed itself at this critical moment, which is equivalent to giving up all the right to speak.

According to Xiao Yao's guess, if the Wei family and the Wu family, who are descendants of the ghost path, don't take advantage of such a good opportunity to stand up, they will be dumber than pigs.

After a few dives, I finally got used to diving underwater for a long time, and I also roughly measured the limit of how long I could last underwater. At his current level, he can hold out underwater for about a quarter of an hour, so he must enter the watchtower in a quarter of an hour.

But to enter the circular waterway, you must first swim through a section of the dark river that flows upward, and then enter the circular waterway, swim through most of the circular waterway, and then enter the bottom of the waterhole inside the watchtower, where you can float.

Xiao Yao carefully calculated his body and the limit time he could hold, and then jumped into the dark river beside him.

The most troublesome part is the upstream section, Xiao Yao uses a dagger prepared in advance to pour true qi into it, so that the dagger can be inserted into the stone wall, so as to resist the downward impact of the water.

A section of waterway of about ten zhang, Xiao Yao moved on the stone wall more than a dozen times like rock climbing, and finally entered the circular waterway.

After entering the annular waterway, the water flow immediately calmed down, and the water flowed in a fixed direction, Xiao Yao chose the side that followed the direction of the water flow, and swam about a hundred zhang, as expected, he found a waterway leading to the center of the circular waterway.

This is the waterway that leads to the central pool of the watchtower.

This section of the waterway is only about 40 zhang, but there is an iron fence every 3 zhang.

Xiao Yao skillfully used the magical changes in the musculoskeletal of his body to follow the gò fence. In fact, Xiao Yao was fully capable of directly destroying these fences, but he did not do so. I just thought, maybe the Witch God Temple will be used in the future.

After about a quarter of an hour of underwater diving, due to the lack of oxygen, Xiao Yao felt that his muscles all over his body had become swelling and sore, fortunately, although his current martial arts level had slipped, it was enough to support and hold on for so long, or it was impossible to be an ordinary person.

Xiao Yao looked up from the bottom of the waterhole and found that the waterhole was only about five or six zhang deep, more than ten zhang square, and there were several rivers around it that continued to inject flowing water, and although there were torches lit above the waterhole at this time, it was still dim.

Xiao Yao chose a corner, quietly jumped onto the shore, and quickly dried the clothes on his body with true qi.

Xiao Yao's appearance naturally did not attract anyone's attention.

After leaving from the waterhole, Xiao Yao found that there was no one around the waterhole, and it was probably dusk outside, and the people inside the watchtower might have been ready to rest.
