Xu Changjin nodded slightly and said, "Thank you, my lord, since that's the case, Changjin will demonstrate first." "At the moment, the two sides are in a competitive relationship, and in order to help Goryeo achieve her wish, Xu Gongnu will naturally not be polite to Lord Lin.

She took a thick red candle, cut it three-quarters, and then on the remaining section, in the direction parallel to the twist, pierced a thin hole, threaded the silk thread through it, sealed it with a candle, and then cut the thread with the candle in its entirety.

"This little sister, can you give me the nine-song jade bead?" The palace maid Xu smiled at Cuiyun and said kindly.

The little palace maid handed her the jade bead, and Xu Changjin perpendicular the small hole of the Jiuqu jade bead to the ground, and slowly threaded the silk thread directly towards the entrance of the Jiuqu jade bead. The inside of the jade bead twists and turns, and the front half of the silk thread is wrapped in a candle, **, which is difficult to penetrate. Xu Gongnu carefully lit the red candle and baked it against the curved hole, the wax thread was softened by the heat, and slowly entered along the curved hole.

This idea happened to seal the silk thread with a candle, the candle was softened by the heat, and the candle tears flowed downward, driving the silk thread forward. However, it needs to be skillfully cooperated, and if it is delayed, it may lead to a situation where the candle seals the curved hole. Xu Changjin is ingenious, her eyes are wide open, she carefully wears the silk thread, she does not dare to have the slightest slackness, and the tip of her nose is as clear as jade, and there is a layer of faint beads of sweat, which looks very beautiful.

It's really an ingenious stupid method, Lin Wanrong snickered, this method can be done by a woman with patience and perseverance like Xu Changjin, and if you change someone else, it will definitely not work. However, this Xu palace maid happens to reflect the national character of the Goryeo people. This point is indeed worth learning from Dahua.

The inside of the Jiuqu jade bead was rugged and tortuous, Xu Changjin spent a long time and returned back and forth several times before the silk thread and the candle passed through the small hole, but the inside of the jade bead had been sealed by the candle, and although the silk thread had been crossed, it could not be pulled. Rao is like this, no one has come up with this method, everyone on the field admired Xu Changjin's skillful hands and perseverance, and immediately applauded thunderously to celebrate her passing.

Gong Nu Xu smiled shyly, bowed to the little palace maid Cuiyun, and said, "I'm sorry." Even though I passed it, the thread could not be pulled, which caused you trouble. ”

Cuiyun hurriedly said, "This sister." Now that the thread has been crossed, you are considered to have passed. ”

Xu Gongnu smiled slightly and said to Lin Wanrong: "My lord, it's time for you." ”

The little palace maid of Cuiyun had already lit a candle and baked the blockage in the curved hole. After the jade beads cooled, the small holes were filled with water, and the water droplets dripped off. proved that there was no blockage inside, and then handed the jade bead to Lin Wanrong.

Lin Wanrong took out a thin bamboo tube from her arms and said with a smile: "The tools I use may be a little unique, don't be afraid, two girls." He opened the bamboo tube, and a small ant crawled out of it, Cuiyun screamed in fright, Xu Changjin's beautiful eyes flashed, and he looked at him suspiciously.

Lin Wanrong took the silk thread and carefully tied it to the ant's leg. He fixed the nine-hole jade bead on the table and smeared some honey on the other end. Xu Changjin sighed, and a sudden look appeared on his face.

Estimating that the smell of honey was almost emanatory, Lin Wanrong placed the little ant in the jade hole. The ant has a keen sense of smell, and when it smells the smell of honey, it looks for the taste and goes away, and the jade hole is pierced in three or two clicks.

Everyone blinked, is this okay? If Xu Changjin's method is accidental and irreproducible, then Lin San's method is simply suitable for three-year-old children, it's so simple, how did this kid come up with it?

"Hahahaha-" The emperor smiled heartily: "Brother Cheng, you are really discerning. Xu Aiqing, this Lin San is indeed a talent. ”

"Your Majesty, I won't tell you. After being in contact with Lin San for a long time, Weichen always had a feeling that there seemed to be nothing that could stump him in this world. Xu Wei said with a smile.

"Really?" The Emperor smiled deeply.

"How did you come up with this, my lord?" Xu Changjin looked at Lin Wanrong and said curiously.

Lord Lin smiled deeply: "If you don't sue the emperor next time, I'll tell you." Xu Changjin's face turned red, and he was embarrassed to speak.

"The first question was answered by Lin Gongzi and Prince Goryeo." The little palace maid Cuiyun announced.

"Lu Dongzan, what do you think? They've already answered a question. Asler said anxiously to the wise man beside him with a worried face.

"Don't worry, Asler, there will always be opportunities, and there are three more questions." Lu Dongzan replied confidently.

"Second topic." Cuiyun tore open another fire paint envelope, only to see hundreds of soldiers suddenly walking in the distance, carrying a log in groups of three, as many as 100 of them, all of which were of average thickness.

"For this topic, there are 100 logs of average thickness on the spot, please separate the roots and tips of each log." Cuiyun said in a coquettish voice.

As soon as the voice fell, the scene fell silent, these logs are all the same thickness, how can you separate the roots and the tips?

Xu Changjin was still thinking intently, but he heard two voices sounding at the same time: "I can separate." ”

A voice came from a distance, in stiff Chinese, from Lu Dongzan, a thinker beside the Turkic envoy Asler. The other voice came from Xu Gongnu's side, it was Lord Lin Sanlin, who had just played with ants.

Xu Changjin said in disbelief: "My lord, do you really know?" ”

Lin Wanrong smiled: "Maybe, you have to try to know." ”

Lu Dongzan also came to the stage, and when he saw Lin Wanrong, he hugged his fists and said: "The contemptible Lu Dongzan is under the seat of the Turkic Viga Khan, and he has seen Lord Lin." ”

Lin Wanrong laughed and said: "It's a guest from afar, since Brother Lu has a way to distinguish which side is the root and which side is the tip, then please come first." ”

Lu Dongzan smiled and nodded: "It's actually not difficult to separate the roots from the treetops, but it may have to carry out some destructive activities. People have age, trees have growth rings, the closer to the root of the tree, the deeper the growth rings more obvious, only need my Turkic warriors, take the head and tail of these hundred logs, sawing the color of the growth rings, you can distinguish the head and tail, roots and tips. ”

What is the age of the annual rings, I still heard about it once, and everyone was confused. Only Lin Wanrong nodded lightly, the Turks can stand for many years without falling, there are indeed talents, not to mention anything else, this Lu Dongzan can be counted as one. Big trees have growth rings, which is a truth that is often mentioned in later generations, but in this generation, it is more and more extraordinary when it comes out of a Turkic population.

"Xu Aiqing, is this Lu Dongzan right?" The emperor asked with a deep frown.

Xu Wei nodded and said: "Your Majesty, the little girl Zhiqing has studied this, the tree has annual rings, the ground is true, the closer to the root of the tree, the more obvious the annual rings will be." This Lu Dongzan is not a mortal, he is the first thinker in the account of the Turkic Viga Khan, known as the national teacher, this time, I am afraid that he will win. ”

"What about Lin San, is it possible for Lin San to win?" The Emperor spoke suddenly, a hint of anticipation flashing in his eyes.

"This, the old minister didn't dare to make a judgment. If you want to win against Lu Dongzan, unless Lin San comes up with a better way. Xu Wei said.

As he spoke, Lu Dongzan had ordered his Turkic shears to cut a large tree from the end of the head and tail, and sure enough, a deep annual ring was revealed at one end. Xu Changjin nodded and said softly: "The world is so big, there are no surprises, and Changjin has learned new knowledge today." ”

Seeing that Lu Dongzan was going to order someone to sawn other logs again, Lin Wanrong hurriedly stopped him with a smile and said, "Brother Lu, as you said, your method is extremely destructive." In this way, the younger brother also has a way to verify the treetops and the end of the tree, and when the younger brother has finished verifying, please ask Brother Lu to choose any ten of them to saw, and the two phases are verified, one can test whether the younger brother's method is fallacious, and the other is to save resources. Afforestation is not easy, you have to take care of the trees and the forest. ”

Lu Dongzan nodded and said, "This method is very good, how can you verify it?" ”

Lin Wanrong walked out slowly, hugged his fist at the hundreds of soldiers who came to fight against the wood, and said, "Please help the brothers and push these logs into the river." ”

Xu Changjin and Lu Dongzan both looked at Lin Wanrong's every move curiously, Xu Wei clapped his hands and said with annoyance: "Oh, why didn't I think of this." Congratulations to the emperor, congratulations to the emperor, this time, we have won again. ”

After those logs entered the water, they jumped in the water a few times, and then gradually quieted down, and then there was a strange thing, a log of the same thickness, but the two ends of the ups and downs were completely different. Lin Wanrong said with a smile: "Brother Lu, according to the younger brother, the same log, the one that floats on the surface of the water is the treetop, and the one that sinks to the surface of the water is the root. What do you think? ”

Lu Dongzan gave a thumbs up and said, "Lord Lin, you are really knowledgeable and talented, you can come up with such a simple method, Lu Dongzan admires it so much." ”

Asler hurriedly walked over and said, "Lu Dongzan, what the hell is going on?" Why are the treetops that float on the surface of the water, and the roots that sink into the water? ”

Lu Dongzan said with a smile: "The big tree is facing the sun, and the water comes from the roots, so the roots of the tree are thick, the treetops are slightly lighter, the surface looks the same thickness, and the inside is different." Let's choose any 10 trees, and we will know when we check the annual rings. ”

A soldier had already stepped forward to select ten logs and sawed them apart, and sure enough, as Lin Wanrong said, the heavy ones were the roots, and the light ones were the tips. There is no doubt that Lin Wanrong's method of selection is more concise and practical, and Lin San and the Turks can pass through this time, but it is an indisputable fact that Lin San overwhelms the Turks, and even Lu Dongzan cannot deny it.

"My lord, where did you get all this knowledge? Can I learn from you? Xu Changjin admired it and couldn't help but ask.

"Self-study, basically self-study." Lin Wanrong snorted: "Gong Nu Xu, do you want to apprentice to me?" Oh, this is not good, I have always been difficult to control myself in the face of beautiful women, if something happens to me and you, then how can I be worthy of the long-standing friendship between your two countries, or not. ”

Xu Gongnu's crystal like jade cheeks flew up with two beautiful colored clouds, lowered her head, and didn't dare to speak for a long time.
