Everyone camped on the spot, saying that they were camping, but in fact there was no "camp". Finding a flat place to spread a piece of cloth was a place to shelter.
When the rest was almost done, there was a faint moon hanging on the treetops in the sky. Bai Amai took Gu Nanshan and the others to take a walk around this black lake first, and take a closer look.
This is a young dammed lake. The age of formation is not too old. Bai Amai pointed to a few directions and said that the peaks had been excavated by man, but the vicissitudes of life were covered by time and the most likely to be built. The location of Ji's tomb has been completely covered by the barrier lake.
"This is the beauty of the theory of the five elements of Yin and Yang," Lao Chen said with emotion. "The Five Elements theory of the Central Plains is not entirely superstition. When they are combined with the terrain, they can avoid floods in the tombs of the ancestors. The disaster situation, as for the collapse and dislocation, and the settlement of the soil, there are certain considerations, but after putting on the cloak of feng shui, it looks like a superstition."
"It's a pity that the people of the Scarlet Ghost Country don't understand this way, otherwise we wouldn't be here looking at the lake and sighing."
After walking for most of the circle, the night was dark, and it became more difficult to see in the woods. Everyone lit a torch, and Bai Liang suddenly seemed to have discovered something. He held the torch and ran on the beach of the lake. Everyone was afraid of what he would get out of. The matter ran for a certain distance, and soon he stopped, squatted down and took the branches to open the wet beach, holding the torch to look at the smelly silt.
Bai Amai asked him: "What's wrong."
"Uncle Amai, we have already walked more than half a circle around this lake, right?"
"Yes, two-thirds of it is there."
"I found that a vacuum zone of vegetation has formed around the lake. There are no plants in this vacuum zone. At first, I thought it was due to the influence of terrain and light, which caused no plants to grow in some areas, but the entire lake just walked through. There are no weeds in the marginal area. It can be seen that the formation of this plant vacuum zone has nothing to do with the topography, but with the lake itself."
Gu Nanshan knows a little bit about this, and guessed that: "It may be affected by the normal dry season and wet season. During the dry season, the lake surface drops and the exposed land is sparsely vegetation. This is a normal phenomenon."
"I thought the same way at the beginning, but I just searched for a few silt, and in all the silt, there was no roots of plants. If it is a half-year dry season or a half-year wet season, it will not be the ground that has fallen out of the ground. No plant roots at all."
The big man guessed: "That's the tide. Early rising tide, flooding the land, low tide at night, exposing the land. After such a long time of soaking, the grass roots will soon run away."
Gu Nanshan slapped him: "The tide is the ocean. Which inland lake has tides."
Bai Liang said: "Uncle Amai, I don't know if it is the tide, but I guess this situation must be related to the frequent cyclical lake level decline. As long as we catch the water level decline period, we will have the opportunity to enter the tomb of Yuji."
Bai Amai pondered: "Can you confirm?"
Bai Liang said: "I can't confirm, because I can't think of why an inland lake has periodic water surface sinking, but we just have to wait. I believe the current water surface height is definitely not his lowest point." )
