Yuan Qingfeng said happily: "Brother Du, I'm thinking about how to measure the height of that huge waterwheel without using a huge ruler. ”

"Do you have eyebrows?"

Yuan Qingfeng shook his head.

Du He picked up a stick and stuck it on the ground, leaving a short shadow in the sun.

Du He said: "The method is actually very simple, you look at the relationship between the stick and the shadow, what can you find? Think about it, and remember to tell me when you calculate it. ”

Du He didn't plan to tell Yuan Qingfeng directly about the method of measurement, but wanted to find something to do for this kid, and it was better to use his brain than to sit every day.

After speaking, he went into the shop to find Lao Yuan.

Old Yuan was roaring at several blacksmiths.

Du He patted Lao Yuan's shoulder and said, "Lao Yuan, don't be angry, go to the back, I'll show you something." ”

Lao Yuan smiled: "See if you hang or not?" ”

In the past few days, the white-clothed arrow Xu Zhengdao asked Bu Huitong to praise the hanging, which was widely spread in the furniture factory, and even Lao Yuan began to learn.

Du He was speechless for a while.

This old way used to look quite serious.,It seems to have changed recently.,I heard that I also quietly went to Pingkangfang twice.,It's definitely not just as simple as playing mahjong.。

He took Lao Yuan to the backyard, and then took out a drawing.

Yuan Tiangang took it and looked at it carefully, but he was confused.

"What is this?" Yuan Tiangang asked curiously.

On the drawing, it was in the shape of a short knife, but it was more slender, the blade was narrower, and there were three sharp blades.

Du He pointed to the drawings and said, "This is a murderous weapon, a three-edged military thorn." The three-sided blade you see is actually a three-edged blade, and I happen to have a physical one. ”

As he spoke, Du He took out the three-edged military thorn and demonstrated it in person.

Yuan Tiangang saw it and gasped.

"This ...... It's a murderous weapon. ”

"That's right, now that the fanged brother is born and died outside, it's time to equip everyone with a decent blade, what do you think of this three-edged military thorn?" Duhe asked.

"Alright, peerless divine soldier."

He grabbed the drawings and said, "Give me three days, and I'll build it for you." ”

"Three days? It's been too long! ”

"Two days...... No, a day and a half, but I have one condition, I must leave the triangular thorn in your hand to me to study. Yuan Tiangang stared at the three-edged military thorn in Du He's hand that flashed with blue light, his eyes lit up, it was a beautiful object he had never seen, the three-sided blade flickered in the sun, and it made people's hearts tremble at a glance, such a divine weapon, even the top craftsmen in Datang could not create it.

Du He smiled: "No problem. Lao Yuan, the three-edged military thorn is the top secret of the furniture factory, the less people know about it, the better, the craftsmen who participated in the creation of the three-sided military thorn, you first draw up the list and hand it to Zhang Jian, let him check it, I don't want traitors in our workshop. ”

Lao Yuan grabbed the three-edged army thorn and yelled: "Whoever dares to leak out, Lao Dao, I will kill him first." ”

That appearance startled Du He.

……

While Du He and Lao Yuan were discussing the three-edged military thorn in the workshop, a game was going on on the martial arts arena behind the furniture factory.

Both sides of the game: Xu Zhengdao, Zhang Wei.

Tournament style: archery, hand-to-hand combat.

Reason for the competition: Zhang Wei has been obsessed with Cheng Yiyue, the second-in-command of the fangs, for a long time, but he has shown his heart many times, either receiving Cheng Yiyue's white eyes, or being pressed to the ground by Cheng Yiyue and rubbed. Recently, Zhang Wei suddenly discovered that Xu Zhengdao was gradually not afraid of women, and approached Cheng Yiyue at two ends in three days, only to find out that Xu Zhengdao secretly had feelings for Cheng Yiyue, and the two turned out to be rivals. After the two learned that each other liked Cheng Yiyue, they were not convinced, so they made an appointment to compete in the martial arts arena.

Match referee: Lu Bu.

Result of the match: The winner can continue to approach Cheng Yiyue, and the loser will roll as far as he can.

In the first game, hand-to-hand fighting, within twenty rounds, Zhang Wei was defeated.

Although this product is known as a white-clothed arrow, archery superman, outstanding light skills, and hand-to-hand combat has always been a weakness, but it can't stand his light skills and flexible body.

And Zhang Wei is actually not from a martial arts family, and he can get mixed to this day with one word: ruthless.

When fighting, he will only move forward, not backward, and even if the enemy wants to exchange arms with him, he will not hesitate to cut off the opponent's arm first.

But without a weapon in hand, Zhang Wei felt that he couldn't exert his strength, and he was abused by Xu Zhengdao.

The second game, archery.

Zhang Wei wiped his face and said: "Everyone knows that you are excellent in archery, today, don't shoot at the target if you have a kind, let's compare who shoots farther." ”

"Don't regret it then." Xu Zhengdao said.

"Come on!"

At the same time, they opened their bows and arrows and shot arrows into the distance.

Woohoo.

Both arrows flew out at the same time.

In the end, it can be seen with the naked eye that Xu Zhengdao's arrow flew farther.

Lu Bu stood up and said, "In the game, Xu Zhengdao won. ”

Smack.

The bow in Zhang Wei's hand fell to the ground at once.

He crouched down, clutched his head, and fell silent without a word.

Xu Zhengdao's face was full of pride, and he patted Zhang Wei's shoulder: "Good brother, don't be discouraged, from now on, Cheng Yiyue's little lady will belong to me, I will take you to Deyue Tower when I go back, give you ten girls, and let you experience how I felt at the beginning, how about it?" ”

Lu Bu next to him glanced at Xu Zhengdao with disdain, and suddenly took out his black stone bow, pulled the bow, and let go.

Shout.

A feathered arrow flew into the air and disappeared.

Xu Zhengdao and Zhang Wei both opened their mouths in surprise.

Lu Bu...... How strong do you have! Xu Zhengdao said in surprise.

Lu Bu clapped his hands and said: "Compared with the young master, it is far from enough, the young master is far away, and the little brother can break the thick pestle at the mouth of the bowl when he appears, in the words of the young master, you ...... It's all scum! ”

Xu Zhengdao: "......"

Zhang Wei: "......"

After a while, Zhang Wei said to Xu Zhengdao: "I am willing to lose the bet, and I hope you treat Yiyue well." I'm leaving. ”

Under the sunset, grasp the back of leaving, a little lonely.

Xu Zhengdao was a little uncomfortable and asked loudly, "Where are you going?" ”

"Tubo, goodbye!" Zhang Wei waved his hand.

Xu Zhengdao scratched his head: "This guy is crazy, what kind of Tubo, Tubo is still thousands of miles away, can't he become a birdman and fly over?" ”

……

The afternoon of the second day.

Du He was reading a book in his room when there was a sudden sound of hurried footsteps outside.

Then I heard Yuan Tiangang's happy voice: "It's done, it's ......"

Du He's eyes lit up, and he hurriedly got up and ran out of the room.

I saw Yuan Tiangang rushing over to this side in ecstasy, holding two shining three-edged military thorns in his hands, waving them excitedly.

Seeing that Lao Yuan was about to come to him, Du He shouted Nima and quickly dodged and jumped away.

Yuan Tiangang came to him, his feet slipped, and he fell forward.

"Ouch......"

Lao Yuan screamed, and the three-edged military thorn in his hand stabbed into the pillar in front of him.
