"There's a path behind here, it's closer." Zhang Laohan stretched out his hand and pointed to a dirt bag not far away and said: "Go over the earthen ridge, there is a path, climb up along it, don't take half an hour." It is to watch out for the wasps, and the wasps on this mountain are so stinging that they are dead. ”

"Okay, old man, stay here." Qiu Shan walked quickly towards the dirt bag, only after walking dozens of steps, he suddenly heard Zhang Laohan's shouting behind him again, turned around and looked, and saw Zhang Laohan chasing after him while raising the things in his hand, and shouted in his mouth: "Housheng, you left the money behind." ”

"Uncle, buy something for my aunt." Qiu Shan waved at Zhang Laohan, but he didn't stop at his feet, and after a while, he left him far behind.

The hill climbed over the ridge, and sure enough, there was a path winding up on the right side of the road, so he walked quickly over it and climbed up the path. Fortunately, the slope is not steep, although the road is narrow, but the shrubs and thorns are all removed, and the walk is quite smooth, which should be the road often taken by nearby farmers to go up the mountain.

Liangshan is not high, only a thousand meters old, the trees are still dense, the hill climbed for about 20 minutes, came to a bare loess clearing, turned around and looked back, saw Sima Dao in front of the eyelids from a distance, in the distance is the breast peak standing on both sides, he has climbed to the middle of the main peak of Liangshan.

If Qiu Shan Sifu turns and walks to the right, he can walk to the ridge where the tombstones of Li Zhi and Wu Zetian are located, and there should be a trail to the right. The hill then climbed up for a while, and sure enough, there was a fork in the road that stretched horizontally to the right, so he went along the fork. The trail should be less indeserved, and from time to time there are thorns sticking out horizontally to hook clothes, which is far more difficult to walk than just now.

It took about ten minutes to walk and stop along the hill and reach the halfway point of the mountain. He looked along the ridge, Sima Dao was directly ahead, and he was in a cemetery that was not open to tourists.

Qiu Shan walked south along the road, and you can already see the sparse tourists visiting along Sima Road in twos and threes. Nearby, an iron railing separates the mausoleum from the attraction. Five or six elderly Western tourists were standing outside the iron railings and taking pictures, talking and laughing.

Qiu Shan thought to himself that if he went out like this, it would inevitably arouse suspicion, and if he recruited the staff of the cemetery, it would be even more unclear. Fortunately, the pine and cypress forests here, and the corners where they are are are are relatively hidden, so I waited in place for a while. When the group of foreign tourists walked away, Qiu Shan looked around, and there was no one around, so he put on sunglasses, quickly rushed to the fence, turned over and jumped out.

Just a short distance from the fence, another group of tourists turned from a distance, Qiu Shan secretly rejoiced, and walked out along the stone path. Not far in front of it, there is a stone tablet about three meters high, the whole body is black, and there is the word "Tang Gaozong Qianling" on the book.

There are two stone lions in front of the stele, the giant is mane, and the body is majestic. Not far ahead, there are 61 stone statues of Fanchen on both sides, which are said to be carved according to the officials of the ethnic minorities under the Tang Empire at that time and the princes and envoys of neighboring countries, and there are no heads for some reason. There are two stacks of cities in the south of the headless stone statue, and Qiu Shan remembers that the sage tablet and the wordless tablet are behind the city gate.

He walked through the city and came to Wu Zetian's wordless monument. Recalling the interview at that time, Li Tai was talking about "the wordless tablet of Qianling", is the secret in the wordless tablet?

“…… The stele you see now is the world-famous wordless stele, and it is also the tombstone of Wu Zetian, known as the crown of the monuments of the past dynasties. The wordless monument is carved from a whole boulder, eight meters high, weighing 100 tons...... "A female tour guide told a group of tourists beside her, Qiu Shan is not far from this group of tourists, and the words of the tour guide are also in the ear, "The wordless monument is empty, why?" There are three kinds of folk legends: one is that Wu Zetian is so virtuous that he can't even express it in words; The second theory is that Wu Zetian thinks that he is guilty, and it is better not to write an inscription; The third theory is that Wu Zetian thinks that his merits and demerits should be judged by future generations......"

Qiu Shan has some understanding of the wordless stele, at this time look at the head of the stele, see the eight dragons on it entangled, the scale armor is distinct, the shape is like a flower, the stele body is strange, the whole body is moist and clean, magnificent and magnificent, I think if there is really any secret in it, it has been admired and touched by so many people for more than a thousand years, can I not see any clues?

He walked slowly around the wordless stele, looking as he walked, and saw that there was a line carved on each side of the stele. The flying dragon dances in the air, faintly soaring. In addition, there are some exquisite floral ornaments and interlaced handwriting, but they are old and have become illegible.

Qiu Shan squatted down and touched the stone bricks on the ground with his hand, and saw that the surface of the stone bricks was rough and tightly buttoned together. Qiu Shan tapped the stone bricks with his fingers, and when he looked up, he saw that there were tourists next to him who were paying attention to his actions, and these movements looked a little strange in broad daylight, so he had to stop his hands and stand up, and seeing that there was nothing else special, he walked to the west in front of the Shusheng Ji Monument.

Shusheng Ji tablet is Li Zhi's tombstone, Qiu Shan knows that this tablet is also called "seven section tablet", even the cover with a seat has a total of seven sections, symbolizing the sun and moon, gold, wood, water, fire and earth, implying Li Zhi's martial arts. Qiu Shan looked at the eaves on the stele, each of the four corners has a protruding stone carving of the wrestler, and then look at the stele face, the handwriting is vaguely legible, it is said that it is written by Wu Zetian himself, and it is filled with gold dust after carving, but it has been eroded for a long time, and it is difficult to find a trace now.

Qiu Shan saw that he could not see other famous halls, so he walked south along the Sima Shendao, and on both sides of the stand were ten pairs of stone statues of Weng Zhong, five pairs of stone horses, a pair of ostrich reliefs and a pair of stone carved winged horses. Walking and looking at the hills, I came all the way to the Huabiao at the southern end.

Huabiao is more than eight meters high, there is a lotus bud-shaped stone ball at the top, and the lower side is an octagonal cloud platform, and the stone pillar stands on the rosette, which looks quite thick from a distance. Qiu Shan walked to the south of Huabiao on the right side, took off his sunglasses, turned his head sideways to look at the pillar, and then the sun shone in the west, dyeing the column body with a layer of golden color, which looked solemn.

The hills and mountains circled around Huabiao a few times, and looked at the Liangshan in the distance, the four fields were vast, showing the magnificence of autumn. He looked up at Huabiao, and the setting sun hit the pillars, revealing strips of light and dark colors. Qiu Shan suddenly woke up to the fact that this Huabiao has eight faces, which are the eight pillars of the Eight Ling Stones. Qiu Shan suppressed his excitement, came to the shadow on the right side of Huabiao, walked back and forth a few steps, stared at the east and west for a moment, and secretly thought that the current direction and the time of the hour are far away, if the sun is in the east, then the shadow should be on the left of Huabiao.

Qiu Shan imagined the position of Huabiao's shadow when the sun rose from the east, and estimated that it was almost Sima Dao. He came to the edge of Sima Dao and looked north, at this time the remnant sun was like blood, and the main peak of Liangshan stood majestically, reflecting the color of red.

Seeing that it was getting late, and the tourists had come down the mountain in groups, it would be okay to come back tomorrow. When he turned around and was about to leave, he saw the group of foreign tourists passing by, and a man in the crowd who was about sixty years old, blue-eyed and silver-haired, slightly thin, and slightly hunchbacked, smiled at Qiu Shan.

Qiu Shan smiled back, and didn't pay attention to this kind of courtesy greeting. After descending the stone steps from the south with the flow of people, Qiu Shan found a taxi back to the county seat of Qianxian County.

At this time, night had fallen, Qiu Shan found a hotel, packed up and went out for dinner, and rushed back to his room immediately after the meal. Since seeing the quatrain yesterday afternoon, Qiu Shan has not had time to check the information, so he took out his laptop at this time and couldn't wait to search for it on the Internet.

The first thing I found was the "Ten Books of Calculation". The Ten Books of Arithmetic refer to the Sutra of Arithmetic of Zhouji, the Arithmetic of the Nine Chapters, the Sutra of the Island, the Sutra of Zhangqiujian, the Sutra of Arithmetic of Xiahouyang, the Arithmetic of the Five Classics, the Sutra of Ancient Arithmetic, the Fixation of the Sutra, the Sutra of the Five Cao Sutras and the Sutra of Sun Tzu, which are ten mathematical works of the Han and Tang dynasties for more than 1,000 years. In the early Tang Dynasty, the astronomer Li Chunfeng added and deleted the ten arithmetic scriptures in the Tang Gaozong period, and they were published as the mathematics textbook of Guozijian, the highest university in the country at that time, which was regarded as a scientific reading book for ancient readers. Since the beginning of modern times, these ancient scientific books have long been eliminated, and several of them have been lost to this day.

Qiu Shan carefully looked at these calculations, and they were all described with specific examples supplemented by pictures. Ancient Chinese mathematical problems were demonstrated using the inductive method, which was very different from the Western deductive method. This also means that there are many examples in the "Ten Books of Calculation", and some examples are very famous, such as the "Hundred Chickens Problem" in "Zhang Qiujian's Calculation", and the "Chickens and Rabbits in the Same Cage" in "Sun Tzu's Calculation". However, due to the lack of mathematical formula symbols, the originally simple mathematical problems are all narrated in words, which is unbearable to read.

Qiu Shan secretly paid to find any clues from these contents, it is really a bit difficult, not to mention that it is not very clear whether the "one sutra" in the quatrain refers to a specific book, or a certain part of the "Ten Books of Suanjing", so he simply downloaded all the relevant information to his mobile phone, and then slowly consulted it when necessary in the future.

He then searched for some historical materials about Qianling and Tang Dynasty culture and religion, and stored all of them on his mobile phone, and it was already 10 o'clock in the evening. When he was about to go to bed, he suddenly remembered Zhang Laohan's red bricks, so he took out his mobile phone, looked at the pictures taken in the afternoon, and picked two photos with better shooting angles and sent them to Hu Tian. I thought to myself, if this red brick was really a rare treasure, he would definitely reply.
