"The other two abandoned ancient cities are not very large, and they should not be the capital." Ye Feihong shook his head and said,

"There are definitely more than three ancient cities in this area." Zuo Dengfeng frowned and shook his head, the last time he entered the desert, Ye Feihong had drawn the location of the three abandoned ancient cities located in this area, when he found that the location of these three cities was secretly in line with the number of Qimen Dunjia, he had thought about finding other cities around the desert to restore the formation to trap the Yin Fire Snake, but he gave up because he didn't know the factors for the formation to work,

"I don't know what the abandoned cities around me have to do with this formation." Ye Feihong picked up the water bag and took a sip, although she had plenty of water, she still only drank one or two sips of water every time.

"As I just said, this formation is like an arithmetic problem, this arithmetic problem is very complicated, what I have to do now is to find as many scattered clues as possible, and then deduce the answer from these broken clues, I don't know what clues are useful, in short, the more clues, the more advantageous." Zuo Dengfeng explained,

"Understood, but there are only three cities that can be found around here now, and the others are covered with yellow sand, where do we start looking for them." Ye Feihong took out the dry food and handed it to Zuo Dengfeng,

"The surrounding cities are secretly the number of Qimen Dunjia, and knowing the three cities, I can deduce the approximate location of those cities covered by yellow sand." Zuo Dengfeng took the dry food and chewed and gnawed,

"There are also several ancient cities buried in the yellow sand." Ye Feihong asked,

"In the future, you can eat as much as I want, and you don't need to save it for me, it's not necessary." Zuo Dengfeng didn't answer Ye Feihong's question, but frowned and reprimanded her, Ye Feihong put the bag of dry food away after handing him the dry food, and he didn't eat.

"There are several ancient cities around here." When Ye Feihong heard this, he hurriedly took out a piece of cake from the dry food bag,

"Qimen Dunjia belongs to the prediction theory, and it is not suitable for using it to set up the array, according to the principle of Qimen Dunjia, the formation can only go rest, life, injury, Du, Jing, shock, death, and open these eight gates, that is to say, there are five other cities around, one of which should be the capital." Zuo Dengfeng ate dry food and explained,

"I'll draw you the locations of those three cities." Ye Feihong stretched out his hand and rushed to Zuo Dengfeng to ask for a pen and paper,

"I'll talk about it after eating." Zuo Dengfeng waved his hand and said,

After eating dry food, it was close to noon, Ye Feihong drew the location of the three abandoned ancient cities again, marked the distance from here, Zuo Dengfeng took the location map and looked at it carefully, and found that these three cities were far from here, more than 300 miles away, and only about 80 miles away.

The word "door" in Qimen Dunjia refers to the rest, life, injury, Du, Jing, shock, death, and opening the eight doors, according to the eight door theory of the formation does not necessarily follow the five elements of yin and yang, that is to say, the formation is not necessarily circular, which adds difficulty to Zuo Dengfeng's calculation of the other five doors according to the known three gates, but the three doors are already known, and then the other five doors are always traceable, after more than an hour of calculation, Zuo Dengfeng determined the approximate location of the fourth ancient city that may exist,

"You have to be safe after I'm gone." Zuo Dengfeng picked up the wooden box and said to Ye Feihong,

"Those ancient cities have been buried in the yellow sand, and you can use this to test whether there are any buildings under the sand." Ye Feihong stretched out his hand and pointed to the two steel drills used to deal with the Yin Fire Snake,

"No, my aura has a penetrating surname, and I can go down to the next three feet." Zuo Dengfeng said and walked out of the shack,

Thirteen ran out of the shack before Zuo Dengfeng, Zuo Dengfeng wanted to leave Thirteen to look after the house, but after thinking about it, he still took it with him, and before leaving, he helped Ye Feihong dig two huge tree roots, and at night the temperature was very low, and lighting a fire could not only drive away the cold but also scare away those remaining humanoid monsters,

Ye Feihong sent Zuo Dengfeng and Thirteen away, and didn't ask Zuo Dengfeng how long it would take to come back.

The ancient city where he settled before was located directly south of the dead forest, and the other two locations marked by Ye Feihong were in the southeast and east of the ancient city, and these two places must also be searched, and no possible clues can be missed.

Afternoon is the hottest time of the day in the desert, Zuo Dengfeng took the thirteen volleys to the south, he did not go in a straight line, because there is no reference in the desert, if you go directly to find the second abandoned ancient city, it may deviate from the route, so he made a transfer in the ancient city where he was before, and finally found another ancient city a hundred miles away in the southeast in the evening,

The scale of this ancient city is roughly the same as the previous one, but the wells here have long dried up, so very few people come in Pingshuo, because no one has trampled on it, the buildings in the city are relatively intact, but the integrity is only compared with the first ancient city, after all, it has been abandoned for more than 2,000 years, the outer city wall has been broken, and most of the buildings inside are dilapidated, and there is more than a foot of yellow sand piled up in the city.

The building materials used in the ancient city are also adobe bricks, these adobe bricks may have been fired, in a state between the soil and bricks, harder than mud bricks, and more resistant to weathering, as we all know that the temperature of burning bricks is enough, burning pottery needs eight, and burning porcelain is at least more than 1,000 taels, and the age of these three things is also from front to back, through the building materials used in this city wall, it is not difficult to see that the construction age of this city is far before the Han Dynasty,

After entering the ancient city, Zuo Dengfeng extended the aura to remove the sand on the ground, and inspected the house by house, the first thing he found was an iron canned food box, canned food This thing is rarely eaten by Chinese, it is dry food carried by foreigners when they explore, and the appearance of canned food boxes indicates that foreigners have come here before,

This discovery made Zuo Dengfeng frown, after the Eight-Nation Coalition robbed Yanjing, countless Chinese treasures were scattered all over the world, these exquisite and luxurious utensils were worth a lot, set off a wave of Chinese fever in the world, attracting a large number of foreigners to China to hunt for treasures, the discovery of the ancient city of Loulan and the discovery of the Buddha cave in Dunhuang led foreigners to the northwest border, these foreign devils to a place are scraping the ground type of excavation, everywhere there are almost no chicken feathers left, After more than 2,000 years of invasion, there is nothing left, and if it is searched by foreign devils, the clues will definitely be destroyed.

Sure enough, Zuo Dengfeng was busy for more than two hours and didn't even find the molded utensils, the only harvest was two boxes of unopened cans and half a bottle of foreign wine, the wine still smelled of wine, and the pattern on the outside of the tin was also very clear, which showed that they had not been left here for a long time, the canned food could be eaten, and the wine could be drunk.

Zuo Dengfeng's first thought after getting these two things was to bring Ye Feihong to taste, this idea made him feel very awkward as soon as it surfaced, he was reflecting on why he thought of Ye Feihong at the first time, but soon he calmed down, Wu Xinyu and Yufu couldn't eat anymore, otherwise he would definitely not be the first to consider Ye Feihong,

"No, I'll have to think about it." Zuo Dengfeng did not let himself go because of this, but leaned against a broken wall to dig deep into the root of the problem, he had to figure out why he thought of Ye Feihong for the first time, this question was not clear It was difficult for him to calm down in his heart,

There is a saying in the Analects called "I say three provinces and my body", which means that people should often self-reflect, Zuo Dengfeng is now self-reflecting, he feels that the people he should think of the most are Wu Xinyu and Yufu, how can it be Ye Feihong, he wants to reflect on whether his feelings have been transferred or scattered,

Thirteen had long known that Zuo Dengfeng had a habit of talking to himself, and after taking a look at him, he went to dig the corner of the wall by himself, and it smelled the smell of gerbils.

Self-reflection is the most difficult, because people have the instinct of self-justification, Zuo Dengfeng overcame this instinct, and finally figured out the reason to make his heart clear, he cares about Ye Feihong out of a kind surname, he takes care of the people around him, never treats others badly, Ye Feihong is his friend, and he stays in the desert with him, he has the obligation to care about her, as for love or not, it is better to self-examine, love someone will have a strong desire for exclusivity, if someone touches Wu Xinyu or Jade Whisk, he will definitely kill, Although he also killed for Ye Feihong, he didn't do it himself, although he was also angry, it was not the kind of anger that others touched their own women, but the kind of anger that others bullied their friends.

"She's my friend, and I should be nice to her." Zuo Dengfeng began to reflect with self-talk, and ended with self-talk.

Although there were no useful clues here, Zuo Dengfeng was not disappointed, he didn't have any hope here, but the half bottle of foreign wine he picked up made him very happy, he forgot to bring wine when he went out this time, although the foreign wine has a bad sweet potato taste, it is also wine,

Zuo Dengfeng wanted to move to the third ancient city in the east immediately, but after seeing Thirteen keep digging, he stopped and waited for it, and waited until Thirteen caught the gerbil before leaving here with it.

Halfway through, Thirteen let the gerbil go, and it was instinctive to catch rats, but it never ate it.

Because it was already late autumn, there were no snakes and scorpions in the desert at night, Zuo Dengfeng walked forward in the starry night, and found the third ancient city after the third watch.

Zuo Dengfeng wanted to take refuge from the wind and sand in the third ancient city, but he didn't expect that the third ancient city was the most seriously damaged of the three ancient cities known, and there were no ruins left, and it had already become a pile of ruins, and there was no shelter from the wind at all.

But apart from this, there was no shelter around the wind, Zuo Dengfeng found a relatively sheltered place in the ruins and sat down with Thirteen recliners,

The wind is not strong tonight, Zuo Dengfeng did not set up a barrier, he was not idle during the period of shelter from the wind, but took the time to observe the surrounding environment, the scale of this abandoned ancient city is much larger than the other two, but the damage here is the most serious, it is far away from the Silk Road, it stands to reason that there should not be too much man-made destruction in the later period, then the reason for the serious damage here can only be the war two thousand years ago, according to the scale and geographical location of this city, it should be a garrison town two thousand years ago, the defense should be the Han Dynasty in the East,

As for whether this is the case or not, he is not sure, because this ruin also has traces of excavation, and valuable clues are missing and cannot be verified.

The next morning, the wind stopped, and Zuo Dengfeng had previously estimated the approximate location of the fourth ancient city according to the direction of the eight gates of Qimen Dunjia, but he did not go immediately, but began to excavate around the ruins of the ancient city.

He must determine whether it was the Xiongnu or the Han Dynasty who attacked here, and it is useless to determine these at present, but if the entire historical event is not restored, it is difficult to guess the mentality of the people in power in Peng State, and it is impossible to determine whether the Yin Fire Snake escaped by itself or was released by them......
