Yes, this is indeed a good method! Hearing Sword Gongzi say this, everyone suddenly realized. If it weren't for the wide range of friends, it would be impossible to know these small things in the countryside if he went deep into the people, and Jian Gongzi really traveled all over the world. It seems that this problem of Mo Yueguo has been solved, and the courtiers who received it from the Han Dynasty thought in their hearts.

"Everyone knows how to put it in the rivers, seas and lakes, so how can you let you put your beak?" the eldest prince sneered and said, "What I'm talking about is judging on the spot, do you want us to go to the rivers, seas and lakes with you now?"

For a while, the Han ministers were speechless, although they felt that his words were a bit strong, but they could not refute it. Such a big piece of wood cannot be carried by a big river, and the imperial capital is too far away from the big river.

"Actually, you don't have to go to rivers, seas and lakes. At this time, Li Changsheng stood up and said: "According to what Jian Gongzi said, the principle of heavy trees in front and light in the back, place a point in the middle of the wood, sink the heavy ones, and upturn the light ones, so that the head and tail are judged." ”

Sure enough, it's a good way! After listening to Li Changsheng's answer, the courtiers realized it. This group of people who had been focusing on cultivation all along, it was difficult to think of such simple common sense of life for a while. And the eldest prince is face changed, and the method Li Changsheng said was the correct answer in his heart.

"Actually, this is not the easiest way...... at this time Li Changsheng said again, as he spoke, he walked around the wood, observed it and said: "I can say the head and tail of this section of wood directly." Pointing to one end: "This end is the head, and the other end is the tail." ”

Pointing it out directly, everyone was shocked.

"How did you know? You are not guessing?" The eldest prince was surprised in his heart, because he knew very well in his heart that what Li Changsheng said was the correct answer. After listening to the words of the eldest prince, everyone was a little suspicious that Li Changsheng had guessed. Because wood only has two ends, half the chance is to guess correctly. It is very likely that people with good luck will guess correctly, and the luck of every one of the eight princes will probably not be bad.

"Do you suspect that I'm guessing?" Li Changsheng smiled lightly: "This tree is one hundred and twenty years old. It is a century-old tree. Growing up in cold regions, thirty years ago, there was a major drought in your country. About 100 years ago, there was a flood in the north of your country...... Could it be that this is also my guess?"

"You ......" Prince Mole was shocked in his heart, the age of the trees, and the location of the material Li Changsheng actually said word for word. And he also accurately said the two natural disasters that have occurred in Mo Yueguo in the past hundred years. If you don't check the history of these things, the people of Mo Yue Country may not know about them. How did he find out?

"You use the ability of a saint to know the world?" the eldest prince couldn't help but glare at Li Changsheng and asked.

"My scholar's cultivation has just reached the pinnacle of raising people, how can he use the ability of a saint?" Li Changsheng said with a smile. When Emperor Wu heard this, he secretly smiled bitterly: even if he used the ability of a saint to know the world, he could only judge the age and type of the tree, as well as the place where it grows, and he couldn't see any drought or flood disasters at all.

Looking at the reaction of the eldest prince, he knew that what Li Changsheng said was true, and the courtiers of the Han Dynasty were shocked. How did he know so well about the history of Mo Yueguo? Could it be that he also judged it based on this piece of wood? Impossible! These people thought to themselves. Of course. The most shocked were the envoys of the three Mo Yue Kingdoms.

"What's the matter, are you satisfied with my answer?" asked Li Changsheng. He not only pointed out the head and tail as required and gave an accurate answer, but also said the growth zone and age of the tree, which was a perfect answer.

"Your answer is correct, but I want to know, how did you find out?" said the Prince of Magic, "If you don't say it, I'm afraid it will be difficult to convince the public." ”

"It's simple. Li Changsheng said: "The patterns at both ends of the cross-section of the tree can accurately reflect the place of growth, the date, and the time of day. One circle and one circle. It is called 'growth rings', and trees grow in a cycle every year. Therefore, the exact age can be known based on the number. In addition, if the sun is abundant and the rain is abundant, the growth rings are wide, and vice versa, the growth rings are narrow and ......"

The tree rings, the patterns of the tree sections, are called tree rings, and there is so much information recorded! Everybody thought it was incredible. They also knew that the cross-sections of the trees had patterns, but they all felt that they were disorganized and meaningless, but they didn't know that they actually contained such a wealth of information! They had never heard of this matter, and if it wasn't for Li Changsheng saying it, I am afraid they would not know it for the rest of their lives.

I heard Li Changsheng say this. Everyone leaned over and looked at the cross-section of the timber. The number is one hundred and twenty, and the width of one circle is wider, and the other is very narrow...... It foreshadows the catastrophe of the year. Annual ring. So wonderful?

Li Changsheng used his own knowledge, not his saint's ability! At this time, everyone understood such a fact. "Your Excellency is really a pedantic genius, I admire you!" the eldest prince had to bow his hand to Li Changsheng and said.

And some other Han courtiers were also very surprised, Li Changsheng was famous for his calligraphy and swords, when did he have such a wealth of knowledge? According to a single tree, he judged the natural weather of Mo Yue Kingdom, and his knowledge can be described as unfathomable. Sword Gongzi Guo Xie stared at Li Changsheng, although he and Li Changsheng were confidants and friends, but at this time, he felt that he didn't know anything about him at all.

In addition, the tree is rooted in the ground, and according to this, the location of the north and south, the veins and other geographical aspects of the tree are not exhaustive. Li Changsheng said lightly.

The people were shocked again! If this is the case, then it will be of great use. You must know that to make weapons, Wenbao needs metal minerals, and exploring mineral veins is of immeasurable significance to the empire. In addition, there is also a Yuan Stone Mine underground, once it can be discovered and occupied, it can be rich and rival the country!

"Dare to ask Your Excellency, how do you find out?" the eldest prince was excited, if he found a yuan stone mine in his own country, I am afraid that the status of the entire country will be changed and the lives of the people of a country will be changed. And Emperor Wu is also very excited, if he can explore all kinds of precious mineral veins in the country, it will have a huge impact on the military and financial strength of the entire country. Such a major matter made the always arrogant Prince of Mole have to bow his head and ask Li Changsheng for advice.

"This matter is very important, so I can't say it to Your Excellency!" Li Changsheng said. How can he easily tell others the big secret that can be related to the fortunes of the country? What's more, this Mo Yueguo and the Han are not of the same heart and mind, and there are even signs of rebellion.

In his previous world, he used technology to look at the mineral resources under the ground where the trees grew and detect their metal content. In Li Changsheng's book spirit, the elemental composition of various medicinal materials can be viewed by refining medicine, and it is easy to explore the ore veins. However, this ability is only possessed by him, and others cannot learn it. (To be continued.) )
