At the moment when Xiao Ling opened the stone gate, the mist in the center of the lake fluctuated for a short time. Suddenly, like a kite on a rope, a large cloud of mist dispersed into the air. The entire area in the middle of the lake is instantly exposed by stone towers. From afar, it looks like a city district.

The fog cleared more than half of it in a short time, and when the stone gate closed again. I saw that several streams of water on the top of the tower were discharged, scattered around, and gradually turned into mist. It's just that the fog formed by this accumulates little by little around the stone tower. In a short period of time, it is difficult to form such a large area of fog.

When the sun came out and shone on the waters, the fog formed more slowly. At this time, fishing boats passed by, and they saw the stone tower complex that appeared in the fog from a distance. For a moment, the people on the fishing boat cheered.

"The legendary ancient city has appeared!"

"Ancient city!

••••••

After a while, a fishing boat couldn't help but be excited and headed towards the ancient pagoda and sailed into the fog area. Seeing that the bow of the fishing boat had just entered the fog, it suddenly accelerated, and the entire hull of the ship was swallowed into the fog. Then I heard the frightened cries of the people inside the fishing boat. Apparently something happened to the people in the fishing boat. After several fishing boats were swallowed, the fishing boats stopped thinking about going to explore.

The news of the appearance of the ancient city in Hongze Lake spread around in an instant. For a time, the number of people who came and went to explore increased one after another. From time to time, people enter the fog area and lose their lives. As a result, rumors about 'ghost towns' also spread around.

As the fog continued to build, six days later, the ancient city that emerged was once again covered by the fog. In this way, the 'ghost town' sank again, but its name spread far and wide.

Xiao Ling stood in the ancient tower, stood still, and began to observe the surroundings. I could see that it was pitch black inside this ancient tower, and I couldn't see anything around me clearly. Xiao Ling groped his way towards the wall of the ancient tower, and then walked along the wall. It didn't take long to find a stone staircase.

Xiao Ling went up the stone staircase to the second floor of the ancient tower. At the exit of the second floor of the stone staircase, Xiao Ling had slowly adapted to the light inside the stone tower. It is clear that there is a stone platform at the entrance of the stone staircase on the second floor, and pine oil is placed on it. Pine oil has dried up and shrunk over time. Xiao Ling took out the flint from his body, swept it on the flint with true qi, and after the water on it was dry, he used the flint to ignite the pine oil.

The light of the pine oil fire illuminates the surroundings, and there are several passages around the second floor, but they lead to other low towers. Xiao Ling found some pine oil sticks on the floor, lit them, and held them in his hands, but he was not in a hurry to explore the secrets in the low tower, but found the entrance of the stone staircase on the third floor, and continued to climb to the upper floor of the tower.

The tower is three stories high and seems to have been exposed to the water. There are two windows on the upper part of the third floor, through which you can see the fog outside the stone tower. Transparent gemstones are installed on the windows to separate the inside and outside. There are many bamboo slips on this floor. Xiao Ling looked closely, and the bamboo slips were placed in piles, very neatly. Apparently someone has organized it into a pile. Looking at the piles of bamboo slips, there is a wooden block in front of it, and the wooden block is engraved with handwriting. Xiao Ling looked at them one by one, and wrote 'Huashan Pai Dan Fang', 'Taishan Pai Dan Fang', and 'Qingcheng Pai Dan Fang'••••••• all of which were famous in the martial arts. Xiao Ling picked up a bamboo slip casually and unfolded it, seeing that it was written with various medicinal materials and materials, as well as matters that need to be paid attention to when refining.

Xiao Ling looked at the bamboo slips that filled the room on one floor, and he didn't have much interest in Dan Dao in his heart, and he didn't look at it at the moment. Continue up the stone staircase to the fourth floor, which is similar to the third. The fourth layer is also full of bamboo slips, but the piles of bamboo slips are stacked higher. Xiao Ling took a preliminary look and saw that there were Shaolin, Wudang, Kunlun •••••• various famous martial arts schools.

Xiao Ling didn't stay long in the four floors, and continued to go up the stone stairs. When I got to the fifth floor, I saw that the floor was full of all kinds of alchemy utensils, Dan furnaces, Dan boxes, and refining stoves•••••• Xiao Ling had seen it roughly, and he didn't study it in depth. Continue up the stone staircase.

The sixth floor of the tower is filled with tall cabinets, which are made of precious nanmu. There are different handwriting on the drawers and doors of the cabinets. Xiao Ling looked and saw that there were 'Ten Thousand Spirit Wood', 'Snake Cave Grass', and 'Dew Withered'•••••• all of which were names of unknown medicinal materials. Xiao Ling opened some of the cabinet doors and drawers. It can be seen that the medicinal materials stored in it have dried up, and some of the medicinal materials have become powdered when touched, and have lost their medicinal effect.

Xiao Ling came to the seventh layer again, and this seventh layer was already the highest level of the tower. The structure of the seventh floor is different from other floor structures in many ways. There are not only windows in the room, but also several ventilation holes. From time to time, the wind blows in from time to time. It's just that the fog outside can't go indoors with the wind for some reason.

Xiao Ling looked out through the window, and in the night, he could see that the original fog under the tower had dissipated. New fog is generating. I heard the sound of 'booming' water, and several streams of water on the roof of the tower were constantly spraying outward. Xiao Ling observed for a long time, but did not see the reason. Then he looked inside. The interior of this seventh floor is very simple. In the middle was a table with two piles of bamboo slips and a wooden block pressed under it. Xiao Ling pushed the wooden block away, picked up the oilcloth, and saw that it was densely covered with handwriting. Xiao Ling looked at it carefully, and it was actually Yindan's real person who left a message.

I am Zhou Yu, the leader of the Five Lakes Gang, known as 'Yindan Zhenren'. I was born poor, frail and sickly since childhood, and was repeatedly bullied by others when I was young. Later, because he was unwilling to be ordinary, he went through hardships, obtained enlightenment, and stepped into the world of cultivation with the body of Yin Dan. After several years, he finally achieved a skill. Then he wandered the rivers and lakes for several years, created the Five Lakes Gang, and enjoyed the wealth and glory of the world. In order to eliminate dust, I have stored the various resources operated by the Wuhu Gang for many years in five places, and handed them over to the five departments for management. The major events in the world can be determined when I am there, and I can control them when I go. The people of the five parts, but there are people who dominate the five lakes and gather the power of the five lakes. In this world, everything should be done••••••

In addition to the brief introduction of Zhou Yuzhizhi, the oil cloth text also focuses on the origin of the ancient pagoda group here, which can no longer be traced back to the existence of the ancient pagoda in the center of Hongze Lake. Back then, Zhou Yu explored the ancient towers in the middle of the lake, and he also tried his best, but he never understood the mystery of the ancient towers. Before ascending to the Absolute Dust Star, Zhou Yu wrote down his understanding of this ancient tower formation on the bamboo slips, and left it here for future generations to study. This week is also a genius in the world. He understood the mechanism of the gate where the ancient tower entered, and then used his own formation to change it slightly. Use the Trait Spirit Stone as the key to open the door. This ancient pagoda group has become a place where only you can enter and exit freely. Then, the alchemy techniques, rare medicinal materials, and precious elixirs collected by the Five Lakes Gang will be hidden in this tower group. created this place of Laojun and left it to future generations.

Soul stone is a rare ore that can accumulate the true qi energy in the human body. Xiao Ling had also seen the introduction of this kind of item when he was in the library pavilion. All kinds of spirit stone veins are very rare on the earth, the earth's spiritual power is weak, and the spirit stone veins formed by the condensation of a large amount of heaven and earth vitality are almost non-existent on the earth. Therefore, in the books of the Earth cultivators, there is only a brief description of the spirit stone, but no specific introduction. Strictly speaking, the spirit stone cannot be regarded as a spirit stone, but is just an ore in an excessive state between an ordinary ore and a spirit stone. Even so, this spirit stone is already a rare item on earth.

Xiao Ling put down the oilcloth in his hand and looked at the two piles of bamboo slips on the table. These two piles of bamboo are the comprehension of the Yin Dan real people about this ancient tower array. Xiao Ling has a natural penchant for Dao knowledge. At this time, I picked up a bundle of bamboo slips and looked at it carefully. The formation described on the bamboo slip is magical and profound, and the annotations and comprehensions of the hidden Dan Zhenren are ingenious and changeable. Xiao Ling looked at it for a while, and then he was deeply attracted. From time to time, he shows a look of confusion and enlightenment. One moment closes his eyes and thinks deeply, and the other pauses open. Xiao Ling indulged for a long time until the pine oil burned out and the room turned black.

This ancient tower group formation was called the 'Whirlwind Mist Killing Array' by Zhou Yu, and this array was composed of many small formations. Each ancient tower is structured into its own formation, and each tower shows its own function with the help of the power of the formation. The formation between the ancient towers is even more ring-ring, which is consistent with the topography of the bottom of the lake. With the help of the natural power of heaven and earth and a mysterious energy, this array was formed. According to Zhou Wei, the key to understanding this set of formations is the mysterious energy, which Zhou Wei can't see through, let alone understand. This is also the key to its inability to comprehend all of this formation. Even because of the existence of this mysterious energy, Zhou Yu didn't dare to test the full power of this formation, and could only observe and comprehend it outside the formation.

The seven-story tower in the ancient tower is the center of the formation, and the formation set at the entrance of this tower is very simple. It seems that the people who set up the formation did it on purpose. When Zhou Yan arrived at the gate of the tower, he broke through the formation and entered the tower without spending much energy with his knowledge of the formation path. However, the tower was empty, and there were no treasures placed in it. On the second floor of this tower, there are passages leading to other small towers, which are also blocked by formations. These formations are very profound, and it took Zhou Yu a lot of effort to comprehend them one by one. I went into the small towers, but found nothing. Zhou Yan was quite disappointed back then, and then he was unwilling, and then turned to study the mystery of the entire formation. I don't want to be deeply attracted for a while, and I have learned a lot of cultivation know-how with this method of continuous research and exploration. Finally break through the bottleneck and benefit endlessly.

Xiao Ling took the pine oil again and continued to study the contents of the two piles of bamboo slips. By dawn, the fog outside the tower had not fully recovered. Sunlight shines through the windows of the tower, making the tower brighter. Xiao Ling extinguished the pine oil, ate some dry food briefly, and then meditated a little, then picked up a bundle of bamboo slips and looked at it. While looking at the contents of the bamboo slips, I walked around the tower from time to time, observing the surroundings and constantly verifying the contents of the bamboo slips.

In this way, for three days in a row, Xiao Ling thoroughly understood the content of the formation contained in this seven-story tower. Intoxicated by it, there are really a lot of gains on the formation path. On this day, I was hungry, and I took out the bag of dry food, and saw that it was empty. Xiao Ling's dry food for exploring the secrets in this ancient tower has been eaten.
