In fact, dozens of miles around this Xiangtan are inaccessible places, and there are very few people who have come to the deep pool for hundreds of years. Except for a very few herb pickers or hunters who tracked rare birds and beasts and accidentally got lost and came to the edge of the pond and saw it from afar, no one approached the edge of the pool.

And the reason why it is called by the locals also has a history.

According to the legend of the locals who live hundreds of miles away, there is a sound of "dong, dong" when around the primeval forest of Xiangtanzi after a rainstorm. Because the terrain of the deep pool is low-lying, the surrounding mountains are steep and towering, so the sound from the deep pool has an excellent amplification effect, the sound of "knock, knock" can stretch for dozens of miles, occasionally heard by the lost hunters, and spread after returning to the village and get its name. But no one knows what is really going on.

Guided by the compass, it zigzagged all the way to the northeast. And since You Ke has undergone miraculous changes in his body and mind, he has become a master of art and boldness. His knowledge is increasing day by day, and he is familiar with forests, trees, birds, beasts, fish and insects, geological structures, etc., which saves a lot of unknown doubts and troubles, and also adds a lot of fun along the way. Ma San'er assists the contractor father, who often does some manual work in contracted projects, and his physique is also exceptionally strong.

The two of them discussed that the compressed biscuits, beef jerky and other dry food they brought were very sufficient, the water source should be easy to obtain all the way, and there was absolutely no problem in maintaining the energy supply of the two of them for at least a week or so.

But no matter how well prepared the two of them are, their physical fitness and field experience are excellent, how can they go from morning to night in this deserted forest, and there is still no trace of the destination, and it seems that they are probably camping in this forest today, so Ma San'er can't help but drum in his heart, and his mouth is also nagging.

Although You Ke kept encouraging him verbally, he also muttered in his heart, if he really got lost in this primeval forest, how would it be good if he went down without results all the way. The two laughed and played from the beginning, twisted flowers and enjoyed the scenery, and gradually calmed down.

When they arrived at a mountain stream, it was getting late, so they decided to set up a tent for the night, Ma San'er took some mountain springs, made a fire to cook, and the two sat by the fire to revise the plan.

It was discussed at the moment, and tomorrow we will walk in the northeast direction for another day as originally planned, and for safety reasons, if there is still no result before 8 pm tomorrow, we will stay for one night and go back. The mountain stream here serves as the middle point and base camp of the route, and the water source and dry food can be guaranteed to a minimum. At the same time, the two of them left a third of the canned food here, which not only reduced the burden of advance but also served as a strategic reserve, compacted with stones, and the canned food had good sealing performance, which could prevent the beast from smelling and destroying it.

After the discussion was settled, the two of them relaxed around the campfire to exchange the cheerful past and present life of their childhood.

"How was your mom doing with your blind date last time?" You Ke asked.

"Oh, you said 'red dust'? Don't mention it," Ma San's head swung like a rattle.

"How do you call it 'Red Dust Rolling'?"

"Look, this beauty walks all the way over, and the dust behind her is flying......" Ma San pretended to exaggerate his lips.

"Hahaha" You Ke instantly understood the meaning of being small, it turned out that Ma San'er disliked other girls who were too fat. The two couldn't help but laugh at each other.

This "haha" sound echoed in the valley, quite loudly.

Suddenly, a very loud and regular "knock, knock, knock" several sounds followed, and the two couldn't help but stand up excitedly.

"It must be nearby!" You Ke said.

The two of them preliminarily judged the direction of the source of the sound, which was the northeast direction, and it seemed that the estimated route was not wrong.

The two had a great conversation at night, but they couldn't sleep because they were excited. So I simply packed up my things around 5 a.m. and continued to march northeast.

It took more than two hours, and it was about a dozen miles away at a relatively fast speed. A line of steep rock walls suddenly appeared in front of them, and there seemed to be no way forward elsewhere, so the two had to venture upward.

When the two of them climbed to the top of the mountain, their eyes suddenly opened up, and a huge body of water appeared in front of them, surrounded by cliffs and dense forests. The two of them seemed to be on the top of one of the cliffs in Xiangtanzi.

You can look at it, although Xiangtanzi is a pond, it should be a lake to be exact. The lake is calm and irregularly shaped, the entire area of the lake is about the size of 25 football fields, and the water in the center of the lake is blue and obviously not shallow. The shallow waters are scattered with boulders that resemble small islands.

The two looked around the lake, but there was no way out, and there was no inlet. This "knock knock" sound is also silent at the moment, and I don't know how it was made. Just in confusion, they suddenly heard the sound of waves, and both of them were surprised, this is just a lake inland, there are no waves and no waves, how can there be a huge sound of waves.

At that moment, I followed the sound of the waves and walked along the lake for nearly half an hour, turning to the southeast corner of the lake. The sound didn't come from the lake, but from outside.

You can look out from the cliff, it turns out that there is a pine forest all over the mountains, it is less than 8 o'clock in the morning, the fog above the pine forest is filled, even if it is a light breeze, the wind and clouds are surging immediately, and the sound of pine waves rolls in, very similar to the sound of the waves.

Looking into the lake from here, the topography changes due to the change of direction.

"Something strange" can suddenly discover something.

"What's strange?" Ma San'er asked.

You Ke didn't answer immediately, but looked to the side at a prominent stone ridge that towered more than 10 meters above him, and climbed it with his bare hands.

When the two of them climbed to the top, they were condescending, and the entire lake was in full view.

"What do you think this lake looks like?" Swim towards the lake.

Ma San'er stared at the lake for a long time. I don't know why, I looked back at You Ke suspiciously, waiting for his next step.

"I think,... The outline of the lake, and the surrounding landmass, is like a miniature map of the Mediterranean! ”

You Ke's ability to have a brain has long been able to memorize and be extremely accurate.

"It's not like! It's a miniature version of the Mediterranean! ”

You can be extremely confident,

"You see, the distribution of boulders in the lake is also according to the islands in the actual map!"

"We are located in the valley of the two rivers of the Fertile Crescent, the birthplace of Mesopotamian civilization, Sumer"

"But this miniature version of the map is the terrain from 4000 BC"
