The three of them continued to walk towards the half of the building that had not collapsed, Li Shidong laughed at the fourth child for dressing so rustic, just like an old man who sold Tang people in a cart in the last century, between the scum of the soil and alternative fashion, the three of them walked into the half of the building with a smile, and suddenly Li Shidong was stunned for a moment, Wan Yanting hurriedly asked what was wrong, Li Shidong frowned and said: "This place is ......" and then the second half of the sentence did not come out, maybe he couldn't say it for sure, so he just shook his headKeep moving.

The three of them carried Liu Qingqing on their backs for a long time, but the strange thing was that they were still at the disconnected staircase, no matter how they climbed up to the bottom of the building, it seemed that there was no end to it, and no matter how they walked forward, they would eventually go to the place where they started, when the three of them realized this problem, Wan Yanting was tired and out of breath, and finally Li Shidong motioned for everyone to rest in place, only to hear him speak: "When I came in before, I felt that this place was not normal, because the qi of the five elements suddenly disappeared here, It felt like the aura emanating from nature was blocked, so I hesitated for a moment, and now it seems that there is really a problem. ”

"This can't be some kind of trap, it's clearly not going to keep us going!" The fourth muttered.

"Huh? You're waiting for me here. As if he had suddenly remembered something, Li Shidong walked straight towards the corridor of the classroom, and after a quarter of an hour had passed, he returned the same way.

"You're walking straight? Or did you turn your head? The fourth asked in surprise.

"I walked straight, it's not surprising, we just walked straight like this but I don't know why we turned around, and we didn't take the initiative to turn around." Li Shidong replied.

"Could it be a ghost covering your eyes?" The fourth asked.

Li Shidong shook his head and said: "Impossible, the ghost can't cover me, not to mention that I have an immortal on my shoulder to guide the way, and the ghost covering the eye won't work for you, you are not in the physique of the Five Elements and Three Realms!" ”

"What could it be?" The two of them groaned in unison.

"That's it!" Suddenly, Yan Ting spoke.

Li Shidong pondered for a moment and shook his head and said, "There are no trees, water sources, strange rocks, and no jinge sharp weapons here, how can you get into battle?" ”

To put it simply, the "formation" is the field formation of the ancient army, which is the product of the development of human warfare to a certain historical stage, which prevailed in the era of cold weapons and died out in the era of hot weapons. In the clan society, human warfare was manifested as tribal conflicts, there was no army at that time, and there was no command, and most of the battles were rushed up, like group fights, so naturally there was no "formation". With the development of history, slave countries appeared, and slave owners began to form organized armies in order to consolidate their rule and plunder slaves (prisoners of war were the main source of slaves), and adopted a certain formation, which was the primitive "array". The "array" appeared in the process of the formation of the army, because of the need to organize the army and command the battle, and integrated the achievements of ancient military science and tactics. The battle formations of the East originated in China. The earliest formation in China is said to have begun with the Yellow Emperor, who learned the formation (Tianyi Dunjia) from the god (Jiutian Xuannu) in order to defeat Chiyou, but this is only a legend, and it is well documented that it was in the late Shang Dynasty. In the 12th century B.C., Shang King Wu Yi to Wu Ding compiled the left, middle and right "three divisions", judging from the naming of the "three divisions", a fixed formation has been adopted. In 1066 B.C., King Wu fell, "Zhou Shi 350 times, Chen Yu Muye", "Chen" through the "array".

The early formation was relatively simple, according to the establishment of the "three divisions", arranged in a word or square, and the formation method was extremely popular in the Western Zhou Dynasty and the Spring and Autumn Period, when it was common to have such a situation: the two armies met in a certain place, lined up neatly, and attacked each other ....... China's formation was developed and matured in the Spring and Autumn Period and the Warring States Period, and the representatives of this achievement are "Liutao", "Wu Zi" and "Sun Bin Art of War". "Liutao" is also known as "Taigong Art of War", according to legend, it was written by Jiang Shang of the Western Zhou Dynasty, according to the examination of the posterity of the pseudo-trust, the book was written in the pre-Qin or early Han Dynasty, and there is no conclusion so far; "Wu Zi" is the art of war of Wu Qi, a famous general of the Warring States Period, which is slightly credible. The above two art of war mainly introduce the car formation. After the Warring States Period, the infantry cavalry replaced the chariot as the main formation of the army, and the formation has changed and developed, and in 1972 unearthed the "Sun Bin Art of War", which describes ten kinds of formations (square formation, circle formation, cone line array, etc.), and the methods used. The contemporaneous "Wei Xuanzi" originally also had a "formation chapter", which has now been lost. After the Qin and Han dynasties, the development of the formation method of the military strategists of the Chinese dynasties also included: Cao Cao, Emperor Wu of the Three Kingdoms, wrote the "New Book of Mengde" (which has been lost, only a few quotations remain), and there is a special chapter on the method of marching and arranging the formation; (Shu) Han Prime Minister Zhuge Liang "deduced the art of war, made eight arrays", "Wuhou eight arrays" passed down to later generations, and had a wide influence. "Tang Taizong and Li Weigong ask right" deeply studied the formation. Yue Fei of the Southern Song Dynasty left a fragment of the art of war to teach the formation. Qi Jiguang of the Ming Dynasty wrote the "New Book of Discipline and Effectiveness" and "The Actual Record of Military Training", explaining the formation in detail, and Qi Jiguang also created his own "Mandarin Duck Array" and "Sancai Array", which showed their power in the War of Resistance against Japanese Aggression. The armies of the various DPRKs in China practiced their formations.

In the historical process of the development of the formation, everyone emerges in endlessly, you can not use people to set up the formation, the function of the formation has also changed from war to sleepy, seizure, mourning and other functions, combined with the Taoist five elements of gossip, with the help of the right time and place, Feng Shui is easy to learn to create an insurmountable obstacle for ordinary people, Li Shidong is right, there is no five elements here, the natural landscape, if you want to set up the formation, it is basically impossible, the so-called Qiao woman is difficult to cook without rice.

But Wan Yanting smiled slightly and said: "There is a person who can, not only does he not need the qi of the five elements, but he can also cut it off and turn it into the qi of nothingness, and he only needs a few marks or a few words to trap people for a lifetime." ”

"Holy shit, there are such powerful people!" The fourth asked in surprise.

"Yes!" Li Shidong nodded heavily, "If the person who is now arranging the formation is the post-graduate of that person, I'm afraid it will be difficult for us to get out!" ”
