The most common maze in the formation seems to be formed by using clouds and mist, and clouds are formed. As long as you deliberately change the arrangement of some reference objects, you can lose your sense of direction.

And in the fog, people who lose their sense of direction can easily get lost. This is the simplest maze.

Therefore, the simplest maze is to use heavy fog. How to get heavy fog? The primary condition is water vapor, that is, there must be sufficient temperature to allow water to evaporate into water vapor. At this time, the water vapor cannot be blown away by the wind, and the wind and water are related here.

With water vapor, it is necessary to cool down. At this time, wind needs to participate. The wind brings air convection, and the temperature will decrease by the fusion of hot and cold air. At this time, water vapor will turn into water droplets, and fog will be formed by attaching to the dust in the air.

At this time, the sun had risen, but Yu Shan had no intention of practicing. He looked at the small rivers crisscrossing in the Tianyuan Valley. Is it difficult to form clouds and mist in such a place?

At this time, Yu Shan thought of the yin energy flowing in the Yin River underground. Yu Shan knew before that the Yin energy in the valley ended up going to Mingyue Lake, but the Yin energy in Mingyue Lake did not overflow, but entered the underground, which means that the Yin energy circulated in the valley and finally entered the Yin River underground.

Now the four seasons in Tianyuan Valley are like spring, which means there is rich geothermal heat below. In addition, hot springs were found in Zhengyuan Village, so there is probably a place where Yin River and hot springs meet under Tianyuan Valley.

When hot and cold meet, water mist will naturally form, and wind will also be generated. Hot air will produce wind. The temperature of the cold air is low, the internal energy of the molecules is small, and the average kinetic energy of the molecules is smaller. The same number of the same molecules occupy a relatively small volume, but the mass is certain, so the density is higher.

Because the internal energy of hot air is large, the average kinetic energy of molecules is large, and the volume is large, so the density is small. Due to gravity, the density of the small will run to the density of the large, so the cold air drops, the hot air rises, forming convection, which also forms wind.

With wind, water vapor, and fog, it seems easy to arrange a maze.

At this time, Yu Shan took out the Sun and Moon Peach Talisman again. The Sun and Moon Peach Talisman is a Feng Shui object that is disgusting and wins, and is a Feng Shui magic tool. Its biggest function is to manipulate Feng Shui.

"It seems that I have gradually found the key point of the formation in Tianyuan Valley!" Looking at the sun and moon peach talisman in my hand, Yu Shan laughed out loud.

There are not many days in Tianyuan Valley that will cause heavy fog, so this can only mean that the formation in the valley has been destroyed thoroughly. If you want to restore the formation, you must first make out fog. With fog, you must control the wind. If you can control the wind, you can control the maze that covers the entire Tianyuan Valley.

What can cover Tianyuan Valley is the guardian barrier formed by the Sun and Moon Peach Talisman. If all this is connected, Yu Shan can't touch the edge of the Tiangui Sect's mountain protection formation, then Yu Shan would be too stupid.

"To make heavy fog, we must clear the river channel, and the adjustment point of all this should be Mingyue Lake. You must know that there was water flowing to Shiwen River in Mingyue Lake, but now, Shiwen River is about to dry up." Yu Shan slowly connected some changes.

Yushan looked at the small rivers crisscrossing the valley. It seemed that in order to improve the formation, we must first clear the river channel. If necessary, the Yin River underground needs to be cleared. Even those Yin River sections that are infiltrated into the underground need to understand the direction of Yushan. Otherwise, Yushan would not be able to return to their original appearance.

"To alternate between cold and heat, we must also use the mountain and sun and moon peach charm to lock the water vapor and not be blown away by the wind. Is there a convective wind force to form inside? This way, the temperature in the valley can be adjusted, right?

I'm afraid that the yin energy in the valley and the yang energy that has never been seen can also be called. Otherwise, the Tiangui Sect would just use the fog to arrange a maze array, which would be too frustrating. A powerful sect cannot rely solely on maze arrays and illusion arrays. It also needs a killing array. I'm afraid that the Tiangui Sect's special skills will be used in this."

Yu Shan thought of the Yin Qi in the valley and the Yin River underground. If you want to kill someone, and you can kill someone invisibly, there is nothing more effective than Yin Qi, Yin evil, dead Qi, resentment, karma, lonely soul and resentment ghost, and evil ghost wood beauty.

However, it is not so easy to effectively utilize all this in the mountains, anyway, Yushan cannot do it recently.

Looking at the terrain in the valley, Yu Shan had a headache. Even though he thought of all this, there was still a lot of trouble to solve in real doing so.

"Come on step by step! Since it is dangerous to enter the East Wilderness Secret Realm, some things should be solved before entering the Secret Realm!"

Since the formation will not be able to be produced for a while, I will think of some other ways to protect Tianyuan Valley.

So, Yu Shan took out a small bag, and the birds on the bag were flashing, radiating a trace of red light very vividly.

"It seems that the Vermilion Bird Talisman can no longer seal her." Yu Shan looked at the Vermilion Bird Bag.

The Vermilion Bird Bag is formed by a Yin Qi Bag painted with a Vermilion Bird Talisman. Such a talisman will not automatically absorb the fire spirit in the air to repair its own consumption. Therefore, under the continuous impact of the internal evil ghosts, the spiritual energy in the Vermilion Bird Talisman continues to flow away. Now, the evil ghosts can almost break through this seal.

"The evil ghost is really a magical existence. It will increase its cultivation as the resentment continues to accumulate." Yu Shan shook his head, wondering what kind of spiritual energy resentment is, and how it was produced. It is impossible to appear out of thin air just by imagination, right?

Resentment can still be felt a little bit very angry, but karma and sin are even more illusory, but this thing does have a great negative impact on people.

A ghost that combines yin energy, evil energy, resentment energy, and karma is a contradictory complex. Because Yu Shan can't figure out where its power is, it is an unexplainable existence.

When Yu Shan returned to the old Bian family house and led the team with the fifth knife, his friends had already climbed to Mount Tai and returned.

Looking at Qiu Furong who was panting and even steaming all over, Yu Shan smiled helplessly.

Yu Shan once saved Qiu Furong, but as long as you are not stupid, you can guess that Yu Shan took away the evil ghost who made a huge noise.

Moreover, even if Qiu Furong couldn't think of this, with Tang Baobao, a guy who is born with yin and yang, how could Qiu Furong not know where her mother went?

What's more, Qiu Furong's perception is unparalleled. I'm afraid Qiu Furong has known about her mother's existence for a long time.

Since she knows, why hasn't she ever mentioned it to Yushan?

I'm afraid she also knows her mother's situation, is she afraid of facing all this?

Although I have never asked about Qiu Furong’s experience, Yu Shan could imagine what she had encountered. Otherwise, how could a young girl with integrity and youth commit suicide?

However, some things need to be faced, at least when the mountains cannot protect them, they need to face them.

Therefore, since it is possible to control this powerful evil spirit, Yu Shan naturally cannot let it go.

Yu Shan glanced at several friends and said, "These are some of my thoughts about Tianyuan Valley, and the usage of this Sun and Moon Peach Talisman. In recent times, your main task is to transform Tianyuan Valley according to my ideas. Let's explore the terrain first! Qiu Furong stays, I have something to tell you."

Yu Shan handed Qian Xiaohao a drawing with a picture of the idea of ​​clearing all the small rivers in Tianyuan Valley. As for whether Yu Shan’s idea can be achieved, I need to do it.

Qian Xiaohao took the drawings and looked at Qiu Furong in confusion, but he didn't say anything and led the others away directly.

As for Tang Baobao, she was a little sad. She knew very well about Qiu Furong. Even the existence of that evil ghost was earlier than Qiu Furong and Yu Shan. So after seeing the black bag with birds in Yu Shan’s hand, Tang Baobao guessed why Yu Shan left Qiu Furong.

"These are always something you need to face, come on." Tang Baobao took two steps, but finally couldn't help it. He turned around and made a cheering gesture to Qiu Furong.

"Ahhh" Qiu Furong was a little helpless, she could only make two meaningless sounds helplessly.

"Come here too." At this time, Yu Shan pointed to the distance, where there had been a figure hiding.

Qiu Laizi came over with a vain. He was completely afraid of Yu Shan and the others, so he was honest in Tianyuan Valley in recent days, and even worked diligently and seriously doing the work assigned by everyone in the valley.

It’s not okay to be disobedient. There are four negative teaching materials around you, which is enough to make Qiu Laizi understand the situation.

Recently, the four thugs were dealt with by the fifth knife and the others. Now they will wake up from time to time when they sleep, which often scares Qiu Laizi.

Therefore, although Qiu Laizi didn't know how the four thugs were treated, he definitely didn't want to be like them.

"Is there something wrong?" Qiu Laizi said a little flatteringly.

Yu Shan smiled slightly and said, "Judgement, whether you can survive safely depends on today."

After saying that, Yu Shan glanced at the autumn hibiscus with an even more ugly face. How unwelcome to the autumn hibiscus was, Yu Shan also saw it these days.

Yu Shan had a long plan for this scumbag, that is, let Qiu Furong's mother decide his fate.

"Judgement? Xiaoyu wants to send me to the Public Security Bureau? I have made small mistakes and don't make big mistakes. Even the government shouldn't arrest me casually, right?" Although Qiu Laizi was afraid, he had no intention of begging for mercy in his tone.

"Is it? Is there any crime? It's not just the court that can judge. Furong, be prepared, don't be excited." Yu Shan raised his head and looked at the sun covered by a dark cloud. Today was destined to be a sunny day.

Looking at Yu Shan's expression, Qiu Laizi didn't know what was wrong, but felt chill all over. He seemed to see a shadow that suddenly appeared in front of him.
