The so-called parallel flow of the three rivers refers to the three major rivers of Jinsha River, Nu River and Lancang River, which flow in parallel from north to south in southwest Yunnan Province. The length of this parallel stream is more than 170 kilometers, about 350 miles.

Xiao Ying nodded, "The range is the area where the three rivers flow together. However, this is too big!"

The parallel flow of the three rivers is clear at a glance on the map, but if we talk about the general mountain and river topography, it can cover a wide range of more than 20 million acres, and most of them are between lofty mountains and mountains.

"Can the scope be narrowed?" asked Yu Yao and Zhong Yu together.

"Yes!" Xiao Ying nodded, "If you combine the Eight Formations, the situation at that time, the northeast is the gate of death because of the entrenchment of the Japanese invaders, and the southwest is the gate of life, and the gate of life is the main vein of the country, which can only be the Yellow River or the Yangtze River, and in this regard, it can only be in the Jinsha River basin!"

The Jinsha River is the upper reaches of the Yangtze River and a part of the Yangtze River.

But even so, the coverage of the Jinsha River in the area of the three parallel rivers alone is very large.

Yu Yao let out a long sigh, "We thought of water transportation before, and we connected the three parallel rivers, but we concentrated too much in the area of Wuliang Mountain, and as a result, we didn't find anything in the Ghost Eye Gate Vault. Now I finally understand, I see!"

"In the light of the situation, water transport was indeed the best way to go. "Xiao Ying interface, "In the middle of the night, it corresponds to the sub-rats in the twelve earthly branches, and the yang is the water ······"

"What?" Yu Yao asked immediately when he saw Xiao Ying suddenly stop.

"I know what formation Ancestor Xiao announced!" Xiao Ying frowned and shook his head.

"It's a good thing to know the formation?" Shangguan Yu said.

Xiao Ying sat down slowly, "This picture has been broken, you don't need to look at it anymore, and sit down, I will listen to you." ”

The four of them returned to the living room, and the sofa was seated.

Yu Yao lit a cigarette and already roughly understood what Xiao Ying meant, "You can break this array, but it is extremely hidden and difficult to find?"

Xiao Ying nodded, "The principle of this formation is very simple, it surrounds one of the four of the five elements to produce an invisible effect. This kind of formation is not unique to my Xiao family, but a very basic Daomen formation, and many people in the Xuanmen know it. ”

When Yu Yao and the three of them heard this, their brows couldn't help frowning.

The secret place of the Ghost Eye Gate used such a simple formation, at least for one reason, it was easy to break the formation, and it was extremely difficult to find the formation.

"If I'm right, the range of this formation is already so small that it only hides near the entrance to the Vault, or even a few dozen square meters. ”

The Jinsha River is in the vast coverage of the three parallel rivers, and looking for this hidden formation of dozens of square meters is almost like looking for a needle in a haystack.

Xiao Ying explained, "The reason why the scope is very small is because the Jinsha River is originally a water vein, and it also implies Jinsha, there are mountains and rocks and forests on the bank, and the five elements can appear in a small range to surround the fourth. ”

Yu Yao said secretly in his heart, indeed, if it is calculated according to this, even a small area of tens of square meters can form a formation.

"This is one of them. Xiao Ying continued, "Second, I said that water, gold, and civil engineering are surrounded, and the five elements in the center are fire, not just based on the terrain. The sub-time completes the vault, and the formation should be the five elements of earth qi, corresponding to the sub-time and earth branches. Among the twelve earthly branches, there are also five elements, yin and yang, the rat is yang and water, and the center of the formation, where the eye of the formation is, must be yin and fire. In response to the principle of water overcoming fire, you can break the formation and enter without the need for a formation charm. ”

Yu Yao asked, "Then this Yin Fire Array Eye is at the entrance of the Vault?"

"yes, it can't be inside the vault. Xiao Ying replied, "It will be a trend of guarding the entrance." At the same time, the method of entering the formation is only on the earthy things that surround it. This one is very simple, just carve a rune on a mountain rock. ”

Xiao Ying's words also showed that although the principle of the formation was very simple, Xiao Zuoqi still left a unique secret method - the runes carved on the stone of the array of mountains must be identified and removed by the Xiao family.

"What is the biggest possibility of this Yin Fire thing?" Yu Yao then asked.

"All things in time have yin and yang, and the five elements are inextricable. With the cultivation of the ancestor Xiao Gong, it is extremely easy to remove yang and protect yin. Xiao Ying thought for a moment, "However, in my opinion, cinnabar is the most likely." Because cinnabar is easy to take, it can also be arranged in the desired shape at will. ”

The three of them nodded again and again, but they all felt helpless.

The large range has been basically determined, and the formation is also familiar to Xiao Ying, and even the method of breaking the formation has been pointed out. However, the search for this array is really too difficult. The terrain is complex and the scope is too small, and even in a large area, it is also a lofty mountain range, and the river is turbulent, and if you want to find out the details bit by bit, it will either take a long time and be too long to calculate, or you will use a lot of manpower.

It is impossible to use a lot of manpower to accomplish this, because it is not enough to have a large number of people, and everyone must be as cultivated and familiar with the formation as Xiao Ying.

"Don't be discouraged, it's better than if we don't know anything. Xiao Ying saw that Yu Yao and the three of them were all depressed, and said, "Actually, there is another gain." ”

"Yes, this is also a major breakthrough!" Yu Yao perked up slightly, "What else do you have to gain?"

"Judging from the scope of the formation and the arrangement of the formation, the vault should not need to open the sealing door. ”

"Oh???" the three of them said in unison.

Yu Yao then asked, "How do you make the 'key' with that big, five, small, and six grimaces?"

"The yin fire cinnabar at the entrance is to deal with the yang water; the so-called yang water is formed by the sub-time and earthly branches to deal with the heavens; after the formation is broken, the entrance can be detected, but if you want to enter, you have to break the array in the formation! These six pieces of money are the things that break the formation!"

Xiao Ying said this, and suddenly smiled, "I guessed before that if there is something that seals the door, in addition to the six pieces of money, the master can also forcibly break it, and the visible door is not as good as the invisible array! Yin Fire Cinnabar guards the entrance, if you can't break the formation, if you want to force it in, it will cause a fire, and the secret treasure may be burned." ”

Yu Yao nodded, "At that time, the situation was urgent, and I chose waterway transportation, and at the same time, I was in the waterway vault, which shows that there is no 'big construction'." Closing the door is very energy-consuming and time-consuming, and it is indeed not a wise move. ”

Yu Yao didn't immediately ask about the purpose of the six coins, which showed that his mind was still gradually calming down.

"These six pieces of money are spent in accordance with the time of day, the three rivers flow in parallel, and the water vapor rushes from the north to the south; when it takes half of the night to break the formation, the shape formed by spending money should correspond to the six stars of the Southern Dipper!" Xiao Ying pointed his finger up slightly.

There are Beidou and Nandou, the Big Dipper, and the six stars of the Southern Dipper.

The six stars of the Southern Dipper are: Tianfu, Tianliang, Tianji, Tiantong, Tianxiang, and Seven Kills; the formation is similar to the Big Dipper, and it is roughly a dipper; however, the "Doukou" of the Six Stars of the Southern Dipper is smaller, and the four stars at the "mouth" are more closely arranged.

Yu Yao narrowed his eyes and twisted his fingers, "Don't say it, this Southern Dipper Six Star is really like a key!"

"And that's not all. Xiao Ying looked around at the three of them.
