Hou Gangwen's unique spiritual academy can extend the time by six times, which is purely a miracle of the use of spiritual power, according to him, if the cultivation is enough, in the spiritual world, it can even realize that time never passes, a moment is eternal, and then reach the realm of immortality and immortality.

Under such conditions, Ji Wenming took advantage of ten days a day, and under the teaching of Hou Gangwen, his knowledge progressed day by day, and after about a month of study, he had already completed all the comprehension of the beast pattern and tiger seal, and even the ease of the mountain had reached the level of entry, and it strengthened his determination and belief in water control - even if it was difficult and dangerous, so far alone, he was firm and had no regrets.

According to the size of the water and the continuous mountain, he determined that only a few water systems such as the Yangtze River and the Yellow River need to be properly managed, so that millions of people in the Great Wilderness can go down the desert island, have a hundred times the land of the past, and their lives can also be improved by several grades.

This night, Hou Wenming went to Hou Gangwen's cave again to study, Hou Gangwen did not lead him into the spiritual school, but took out a beast skin scroll, put it in front of Ji Wenming and said to him: "Apprentice, with your academic progress, now, you can barely comprehend this thing!"

This animal skin is white and greasy, and the half-inch-long hair flashes silver, which looks quite extraordinary, and Ji Wenming said strangely: "Teacher, what is this?"

Hou Gangwen smiled and said, "Well, this is the very important thing related to your great cause of water control!"

Ji Wenming had asked his teacher for the river map from the Yellow River, and at this moment he suddenly woke up to the fact that this white fur record is probably the book of river maps!

Thinking of this, his hands suddenly trembled a little, and he looked at Hou Gangwen happily and said, "Could it be that this is ......?"

Hou Gangwen nodded lightly and confirmed: "That's right, this is the river map, and your Luo Shu shines brightly! This world's rivers, each of them should be star-patterned celestial phenomena, each of which has its own inscription imprint, but unfortunately, with the passage of time, many inscription imprints have been lost, just like the Dao pattern, no one can understand the meaning contained in it, until I found them! The same is true for Hetu and Luoshu, maybe you can find more fragments of Tianshu in the future, I hope you can make good use of it!"

Ji Wenming picked up this river map, and slowly opened it with a flick of his fingers, and there were still rows of concave and convex star marks on the animal skin, with black and white starlight, flashing on the animal skin.

The same star marks as Vena, the same mottled dots, but they are different sequences, the points of Vena star marks are fifty-five, but the number of star marks on the river map is fifty, there are five star marks in the center of the two pictures, and Vena is divided into two layers, upper, middle and lower, left, middle and right nine directions, and the river map has only five directions, upper, middle, lower, left, middle and right, and the inner and outer three-layer structure, in comparison, the river map is more complicated.

Ji Wenming tried his best to find the law of the number series, but he still couldn't see it really, and he couldn't help but ask Hou Gangwen with his eyes. The old man stroked his beard and said with a smile: "Why? I don't understand? Your learning attitude is so rewarding as your teacher! Hahaha!

"Where one, three, five, seven, and nine are the days, and two, four, six, eight, and ten are the number of the earth, and the sum of the days is twenty-five, and the sum of the earth is thirty, and the sum of the two numbers is fifty-five. The number of days in the Book of Heaven is odd and yang, and the number of the earth is even, yin, and yin and yang are mutually exact. The numbers of the upper, lower, left, right, and middle groups of this figure are related to the five elements of fire, water, wood, metal, and earth, respectively. The generation and transformation of the basic forms of metal, wood, water, fire, and earth, and even the development of all things, can be inspired from this diagram. ”

Hou Gangwen played around for a long time, then looked at Ji Wenming again and said, "Understood??"

Ji Wenming shook his head in confusion, "Teacher, this number series is too difficult, I still don't understand it enough!"

Hou Gangwen sighed helplessly: "Hey, I have studied for hundreds of years, and I have some experience, I want you to understand the truth overnight, it is indeed a little difficult for you, but it doesn't matter, even if you don't understand it, you can use it!"

Ji Wenming's eyes lit up, and in the face of the profundity of the Book of Heaven, he was about to give up, but he heard that he could use it if he didn't understand it, and he was suddenly interested. Hou Gangwen said: "You only need to connect all the star marks in the order of one, two, three, and four with your divine thoughts, and the Book of Heaven will automatically come into play! As for these star marks, you can't see through the essence anyway, you might as well lock them as a password!"

Ji Wen said strangely: "Combination lock?"

Hou Gangwen smiled: "It's a kind of spiritual lock, without opening this lock in the right order, you can't get the items inside the spiritual barrier!

Ji Wenming nodded and said, "Of course I want to learn this kind of ability!"

Hou Gangwen pinched his fingers, calculated for a moment, and said: "I am not very proficient in this skill, it just so happens that there has been a bustle in the Eastern Spirit Domain recently, and many academies have come together to hold a discussion activity, and when the time comes, let my old friend teach you the ability of the combination lock!"

Ji Wenming bowed and saluted: "Thank you, teacher!"

Hou Gangwen waved his hand and said: "It's not in the way, it's not in the way, I hate kowtow worms the most!

Hou Gangwen turned his head and fell asleep on the stone couch, and Xi Wen sat at the entrance of the cave, took out the tortoiseshell Luo book, and put it together with the Longpi River map, and used the moonlight to study the mystery.

I saw a faint silver moon light swaying down, shining on the tortoise shell and the fur of the dragon horse, and the two heavenly books reflected each other, and a little light flickered.

Ji Wenming tried to hook the star marks on the river map with his divine sense, but the river map did not react, and he used his divine sense to hook the star marks on Luo Shu, but Luo Shu did not respond.

Ji Wenming was anxious in his heart, and hooked Luo Shu after hooking the river map with his divine sense, from one to nine, from nine to one, this change in his divine sense, Hetu Luo Shu suddenly reacted, and a broad energy rose from the heavenly book in his hand, crashing into Ji Wenming's body, Ji Wenming's chest suddenly moved, and seven star marks suddenly appeared on the skin, and began to emit a burst of irregular flashing together.

The reason why this kind of flickering is very irregular is because the seven star marks on the surface of Xi Wen's body do not flash at the same time, but flash in the order of one, two, three, four, it is difficult to judge which star mark will flash, but it follows the order from one to seven and from seven to one.

After the star marks on the surface of the body of Ji Wen flickered, the star marks of the two heavenly books slowly adjusted the frequency, and the rhythm of the flashing gradually became the same as the star marks on the surface of the body of Ji Wen, and then, the tortoise shell and the dragon horse skin suddenly shook, flew up out of thin air, and attached to the body of Xi Wen Ming one after the other. The tortoise shell landed on the back of Xi Wenming, and the dragon horse skin was wrapped around Xi Wenming's chest, turning into two pieces of skin again, no longer separating from each other.

Ji Wenming was shocked, and hurriedly turned his head to look at Hou Gangwen, Luo Shu was snatched by himself, but Luo Shu is the teacher's thing, and he cultivated so indiscriminately, and he lost it, he was really ashamed of his kindness to the teacher!

Unexpectedly, when he turned his head, he saw Hou Gangwen smiling and nodding at him, muttering: "Heaven and man induction, heaven and man induction!
