After the two walked out, Fang Ling did not breathe a sigh of relief. The thing in Zhao Meng's body should be the root of the strange disease. However, whether he could really solve the strange disease like this depends on tomorrow.

After a while of rest, Xi Zhengyong sent someone to a dinner party, saying it was a dinner party, but it was even more like a family having a meal. There were only a few real royal members of the Xi Kingdom royal family, and even if they were the commander Li, the guard commander and other officials, there were only a dozen people.

During the meal, everyone was full of gratitude to Fang Ling but was just a bit of a word. Compared to the intrigues in the imperial city of Chu, the people here seemed much simpler.

At night, after Fang Ling returned to the room, he opened the window and began to practice the technique of Sun and Moon Resolving. This technique of Sun and Moon Resolving is completely different from the ordinary internal skills and mental methods. During the day, he can only practice the technique of Sun and Moon Resolving and absorb the sun fire power. Moreover, if he uses the solar fire power during the day, he will be more powerful, but at night, he can only practice the technique of Moon Resolving and absorb the moon yin ice power, and the power of Moon Yin ice power at night will be even greater.

However, during the practice, Fang Ling was surprised to find that the moon yin ice force contained in the air at the bottom of the valley was very thin, or it could be said that there was almost no such thing as practicing the mind method. No matter how you practice the mind, you could only absorb a very small amount of moon yin ice force.

Fang Ling secretly suspected that the moon yin ice power is a kind of qi of heaven and earth, and it can be said to be omnipresent. As long as there is air circulation, there will definitely be one. Although the valley bottom is thousands of feet deep from the ground, how could it be that the moon yin energy is not as big as such a large area?

He couldn't help but stand up and looked outside through the window. The night was hazy and the moon was not visible. Only the colorful mist covered the field of view. The more he looked, the more strange he felt.

Early the next morning, Fang Ling got up and when he pushed open the door, Wei Cheng was guarding outside the door.

So, after calling Zhao Meng, Fang Ling checked him again. This check didn't matter. Fang Ling couldn't help but sank, just because he found that another abnormal breath was found in Zhao Meng's abdomen.

This abnormal aura was obviously just produced last night, and it was much weaker than the previous one.

Fang Ling checked Wei Cheng's again and found that the abnormal aura in Wei Cheng's body was still there.

He then asked Zhao Meng about his actions last night in detail. He guarded outside the door for a while last night and went back to rest directly.

Fang Ling narrowed his eyes slightly. He had not drunk water, had eaten rice, had never come into contact with any plants, and there were no animals at the bottom of the valley, but the source of this strange disease actually came out of thin air.

When Fang Ling's eyes were cast on the colorful mist in the sky, his heart moved, yes, air!

If this strange disease is a poison, and this poison is transmitted through the air, everything will be explained!

He quickly asked Zhao Meng: "Do you think this fog is related to a strange disease?"

Zhao Meng shook his head and said, "Our ancestors had long doubted the fog, but if it was really a fog, there would definitely be a way to spread it. However, at that time, they searched all over the valley, but there were no plants or caves or even holes that sprayed out the fog."

Wei Cheng nodded and said, "According to records, our ancestors had conducted a very careful search of the entire valley. And according to observation, the concentration of the fog in the entire range is very balanced. If there is a source of fog dispersing, it must be thick near the source, and the distance is thinner."

Fang Ling frowned when he heard this, yes, it's been three hundred years, and people at the bottom must have carefully inspected and searched the possible poison sources, and it would be impossible for such a big mistake to occur.

But, if it has nothing to do with fog, what is it?

His eyes suddenly lit up and he remembered something: "Where did the detoxification weed be found?"

"Studying." Zhao Meng replied.

"Studying? It sounds quite sinister." Fang Ling said.

Zhao Meng said, "It was a very hidden place. There was a stick of incense here. There was only a very hidden path to pass through. After passing through it, there was a cliff with only a small area below. The detoxification weed was found on one side of the cliff. There were only a few plants at that time. Later, after careful cultivation, each tribe had a place to cultivate."

Fang Ling said curiously: "Has anyone been there under the cliff?"

Wei Cheng replied: "It can go down there, but after going down, the place is not big, and there is a pool in the middle. The water in the pool is extremely cold, and some guards have dived down. However, because it is too cold and cannot dive down, because it has nothing to do with the fog and is not our water source, so I didn't check it later."

Fang Ling stood up and said, "You can take me to the fallen cliff for a walk."

"This..." Zhao Meng and the others were stunned for a moment and hesitated, "Young Master, the place is remote, it is a place where three people don't care. Although the detoxification weed is gone, if you encounter an enemy there..."

Wei Cheng said: "If the young master must go, then the emperor should send someone..."

Fang Ling waved his hand and said, "You don't need to notify the emperor about this matter, so as not to worry about him. We just go and come back. If we encounter an enemy, I have my own way to deal with it."

"This..." The two looked at each other and nodded.

So, under the leadership of the two, Fang Ling left the imperial city and headed north. The jungle passed by was deep, and there was no sound. Compared to the forest full of life outside, under the valley, there were only humans except plants.

Not long after, we finally arrived at the Cliff of the Foot Cliff safely. As the two of us said, it was in a gap in the mountain wall. The road was narrow and difficult to walk, and it was covered by trees. It was inconspicuous. Who could have expected that there was a world behind it?

On the cliff, there are weeds around. Standing on the cliff, you can see the ice pool below. The white mist that emerges from the pond rises, and you can feel a chill when you stand on it.

The three of them walked slowly along the cliff beside the cliff. When they landed at the edge of the pond a hundred meters deep, Zhao Meng and others couldn't help but tremble. Fang Ling's cultivation had reached the realm of strength, and his ability to resist cold was much higher than that of the two, but he could feel a clear chill.

The water in this pool is actually not big, only a few feet long, because the temperature here is very low all year round, and the surrounding rocks are covered with thin ice and there are no weeds.

Fang Ling moved his arms and smiled and said, "I'll go downstairs to check it out, you guys are waiting for me above."

"This, young master, it's very cold below. If you accidentally freeze your hands and feet, it will be troublesome!" The two were shocked and quickly reminded.

Fang Ling smiled slightly and said, "Don't worry about me. I'm not so stupid that I jumped down and lost my life. But you have to be patient, because I don't know how deep it is."

After saying that, he took a deep breath and his body shook slightly. Under this shock, a thin layer of red light appeared outside his body, which was the protective true energy formed by the power of the sun fire!

Zhao Meng and the others were shocked. Although they both knew that Fang Ling had martial arts, they could actually use the Sun Fire Power, which was only a commander-level figure who could refine it.

Just as the two were stunned, Fang Ling had already jumped into the ice pool.

As soon as he entered the ice pool, Fang Ling felt a biting chill. This chill could actually penetrate the protective true energy and invade the body, which was amazing.

The sun fire power in Fang Ling's body immediately reacted, churning in his body, protecting his body.

The pool water is deep, but after Fang Ling entered the Hard Power Realm, his eyesight has improved greatly. Although he still cannot reach the state of being able to see things at night, he can barely distinguish them in the pool water.

There was no moss on the stone wall of the pond, and it was bare. He tried hard to sink. Every time he sank a little more, he would feel more pressure and the chill was one point higher.

However, the technique of Sun and Moon Resolving is a method of cultivation after all. Although Fang Ling only has the cultivation level of the strength level, his potential can be realized is quite great.

Especially Fang Ling's will is as hard as iron, and he wanted to explore the mystery of this ice pool, so nothing can stop him.

I don’t know how long I had been diving, but my vision in the pool water had become extremely dim. Suddenly, Fang Ling found a ball of white light flashing at the bottom of the pool.

He quickly dived down, and when he saw the white light clearly, he was shocked.

This is a stone like a mountain, about half a meter high, and it is as white as jade. The reason why Fang Ling was shocked was because he had seen this thing on the ninth floor of the Heavenly Prison.

This is the Tianshan Ice Mother who created the cold pool of water in the room where Xiao Xue was detained!

Although only a corner of Tianshan Ice Mother was exposed in the pool water, Fang Ling would never admit his mistake after seeing that glance. The thing in front of him was definitely Tianshan Ice Mother.

Only Tianshan Ice Mother can create such a biting and cold pool water.

A thought suddenly flashed through Fang Ling's mind. Tianshan Bingmu appeared in this place, which proved that there were people at the bottom of the valley before, and long before the arrival of the people of Xiguo.

You should know that when Tianshan Ice Mother picks up to the extremely cold place in Tianshan, it often requires a lot of manpower and material resources to obtain one side. However, this side in front of you is much larger than what you see in Tianlao Pool. Who moved this thing here?

The purpose of creating this ice pool must have a certain intention.

Fang Ling immediately searched at the bottom of the pond. Although Tianshan Ice Mother had light, it did not illuminate the entire bottom of the pond. Fang Ling had almost reached the limit at this time. Once time delayed, even his life would be in danger.
