Lao Huai'an is a famous cultural city with a long history, more than 5,000 years ago, the ancestors of the human world have been working hard and multiplying here, and formed the earliest primitive culture in the Jianghuai River Basin - Qingliangang culture.

It is a more important branch of the Neolithic Age, belonging to the stage of transition from matrilineal clan to patrilineal clan, its distribution area is very wide, because the first place to be found later is in Qingliangang in old Huai'an, so it is called Qingliangang culture.

Qinglian post is in the northeast of the old Huai'an, Qinglian Village, Songji Township, two miles south of the "Waste Yellow River", more than 70 miles away from the old Huai'an City, Qinglian Gang is because there is a Qinglian Temple in the early years of the gang, so the temple is named "Qinglian Gang".

Among the cultural relics excavated at the Qingliangang Cultural Site, there are many stone tools such as stone shovels used to turn the soil, stone knives used for harvesting, stone axes used for cutting, and enough stone lifts and gangs for processing grains.

The unearthed relics of the Qingliangang cultural site show that the ancestors of the human world at that time had quite advanced hand-made technology, which was able to manufacture exquisite stone production tools and use these stone tools for labor production.

These stone tools are made of hard granite and quartz stones, reflecting the primitive way of agricultural production at that time, and have occupied an important position in the entire economic life of the clans and tribes in the Qingliangang cultural era.

According to the data, in the remains of Qingliangang, carbonized indica rice grains were also found, indicating that there was abundant rainfall and a warm climate in this area at that time, indicating that the clans and tribes living here opened up a lot of paddy fields at that time.

It also shows that rice should have been widely planted in the paddy fields they opened up at that time, and the cultivation of rice also provided people with a new main means of livelihood and laid the foundation for the later development of this crop.

The information also inferred that during the Qingliangang culture period, the humans here had already lived a settled life, and the houses they lived in were mainly rectangular or garden-shaped ground buildings.

In addition to this Qingliangang primitive cultural site worth exploring, Zhi Lingqi also found an ancient legend that has been passed down for a long time in the library's computer, that is, the rumors of Laozi Mountain in Xuyi County, Huai'an.

Laozi Mountain is located in the northeast of Xuyi County, about 60 miles away from the county seat, from the Huai River downstream, past Laozi Mountain is Hongze Lake. This mountain is surrounded by water on three sides, the head is high and the tail is low, and the horizontal pillow is above the blue waves, like the throat of Hongze Lake. Locals also call it the small island of Hongze Lake.

Legend in the Spring and Autumn Period, Lao Tzu traveled the world, rode a green ox to pass by the Huai River, saw the top of this mountain colorful glow, the foot of the lake is vast, and felt that it can embody the Taoist spirit of "human law and earth, earth law and heaven, heaven law and Tao, and Taoism and nature".

So Lao Tzu lived in seclusion on the mountain to refine Dan, and later this mountain was named Lao Tzu Mountain. Laozi Mountain is also known as Danshan, there are many places of interest and historic sites here in history, and there are still Laozi Alchemy Pool, Laojun Cave, Qingniu Traces and so on.

It is said that Lao Tzu lived in seclusion on the mountain for several years, after Dancheng, he rode on the green ox and went south, leaving a line of cow hoof prints about five inches deep and a diameter of about five inches on the mountain stone, and the hoof prints pit was wet all year round, which was the famous "green ox trace" scene of Lao Tzu Mountain.

There is also a saying that after Sun Wukong made trouble in the Heavenly Palace, Taishang Laojun, that is, Lao Tzu, helped Erlang God to irrigate the estuary by the East China Sea, and firmly trapped Sun Wukong with a golden steel ring, so that he was bound and trapped, so Wukong held a grudge against Lao Tzu.

Sun Wukong was later pressed under the Five Elements Mountain, and Guanyin Bodhisattva released him because he wanted him to protect Tang Seng to learn scriptures. After Sun Wukong came out, because of his hatred for Lao Tzu, he came to the place where Lao Tzu was refining pills by Hongze Lake.

He overturned Lao Tzu's immortal bed, destroyed the gossip furnace, and destroyed all the treasures of Lao Tzu when he was alchemy by Hongze Lake, and then he walked away with hatred.

Seeing these different versions of legends, Zhi Lingqi also smiled slightly: "Legends, you might as well go and explore, if you have clues, it's good, if you don't have clues, you can't have him, if you want to count on a target, this possibility will not have much chance."

Regardless of whether or not some clues can be found, in the territory of Huai'an, these two places should be explored, and now in the absence of exact information, if there is one in ten thousand hopes, it must be done with a hundredfold effort.

Although the search for a common net is a stupid way that is difficult to achieve, but in the current situation, there is really no other way to use, if your inheritance memory can give a clear location, why do you need to do this?

After checking the information recorded on the computer repeatedly, Zhi Lingqi was finally convinced that in the land of Huai'an, except for the two places of Qingliangang and Laozi Mountain, it was impossible for other places to be related to the follow-up exercises he was looking for.

By the time Lingqi walked out of the library, the sun had already set, and after discussing with Yiyi and Linglao, Lingqi decided that the three of them would go to taste a delicious meal first, and then the three of them would take advantage of the night to conduct a stealth night exploration operation.

Considering the geographical location of Qingliangang and Laozi Mountain, Qingliangang is located in the northeast of Huai'an, while Laozi Mountain is located on the Hongze Lake in the northeast of Xuyi County.

Therefore, in order not to take the wrong road, of course, the first place to explore, it should be Qinglian Gang, the original cultural site of Qinglian, after exploring the places related to Qinglian culture, and then look back to the south to explore the Laozi Mountain in Xuyi County, which is just convenient for the later trip.

After Lingqi, Yiyi and Linglao finished dinner, the sky was already completely dark, and the three of them naturally did not delay any longer, and after walking to a secluded place, they put Yiyi and Linglao into the internal space, and then flew quickly to the destination.

It didn't take ten minutes to arrive at Qinglian Gang, and Zhi Lingqi quickly explored the specific location of the Qinglian Gang stone artifact excavation site through the powerful exploration function of the Heavenly Eye Vision, and then flew over the site.

Let Yiyi and Linglao stay on the periphery of the ruins to guard and wait, and Zhilingqi used the Heavenly Eye Sense to investigate in detail, in fact, it stands to reason that they don't need to come here to explore at all, because this place has long been excavated by archaeologists.

There is almost no possibility of the existence of leftover items, but Zhi Lingqi does not think so, he will not let go of the slightest possibility, otherwise it will not be a pity if there is a leak at that time, therefore, he was confirmed on the spot once.

Although in the end, he didn't find anything here, but he didn't regret it, and if he was asked to choose again, he would still confirm it in this way, which is the careful principle of "I'd rather repeat than miss" that people are used to.

After finding no clues here, Zhi Lingqi rushed to the museum with Yiyi and Linglao according to the location of the Huai'an Museum found on the library computer in the afternoon, and also used the Heavenly Eye Sense, and began to explore outside the gate of the museum.

Just like the previous exploration of the Qinglian Gang ruins, the Heavenly Eye Awareness Combat Skill function of the Supreme Spirit Enlightenment was fully activated, and it slowly carried out a scanning exploration like a searchlight, never letting go of any item, even if it was just a grain of fine sand.

At the same time, Zhi Lingqi also attached his chaotic spirit vein sensing to the Celestial Vision, also wanting to see if it was possible to resonate with the excavated items in the museum, as long as there was resonance, it was possible to be related to Pangu.

Naturally, it is very likely that it is related to the follow-up cultivation exercises, and even if there is no direct connection, there may be indirect clues, so his current investigation is very serious, very careful, and very patient.

After nearly two hours of careful investigation, he was still disappointed after all, even if he explored all the excavated items in detail, even the symbols and words on the items were carefully scrutinized, it would be useless.

During the entire exploration process, the chaotic spirit vein induction of the Supreme Spirit Qi did not produce any abnormal movements, which shows that in the Huai'an Museum, there must be no related items that they are looking for.

Didn't find anything valuable, or related, although Zhi Lingqi was a little disappointed, but not depressed, this was the result he had predicted a long time ago, so he took Yiyi and Linglao back to the hotel.

During the rest in the second half of the night, Zhi Lingqi closed his eyes and seemed to have fallen asleep, but the Consciousness of the Sea was like a movie, flipping through the inherited memories that had awakened again, and Yiyi next to him also knew the severity, so he didn't bother him.

After reading the inheritance memory twice in a row, and not getting further information, Zhi Lingqi fell asleep sleepily, and used the Heavenly Eye Sense for a long time twice in a row, and the consumption of soul power seemed to be not small.
