The Baisha tribe, the tribe leader, widened his eyes. He never thought of attacking the Han people, nor did he want to offend the Han people. The wise men in the tribe established an idea with him, so that the Han and Xia countries could fight and maintain balance, and that the tribe that connects to Tianhu could last for a long time.

The Han envoys were three young Zhi Gewei. They sat in their seats with a cold look on their faces waiting for the Baisha leader to give a reasonable explanation.

After a few remarks, the leader of Baisha became anxious. The wise man of Baisha touched his beard and said seriously: "Since the messenger does not believe it, we can swear!"

Swearing is the most authoritative approach in this era. When I heard that the wise man in Baisha had such an idea, the three Zhigewei believed that it was not done by the Baisha tribe.

"They pretend to be your Baisha tribe. Maybe there will be another next time, so you'd better check it out." Zhi Gewei reminded him, after the three of them left.

The leader of Baisha smashed the clay pot on the table, "Who dares to pretend to be us! Let the tribe members check, especially those from those two tribes!"

The wise man took out a piece of animal skin and looked at it for a long time. It was the locations of the tribes of Jietian Lake. His eyes were on the archipelago on the north side of Jietian Lake. "That Linshui tribe is very active recently, so you can go and have a look."

Yan received the king's order and found the group of disguisers before December and used their tribe members to pay tribute to the dead caravan members. "It's a bit difficult and needs to be paid. The person comes to find the leaders of the tribes of Zhitianhu. I have something to discuss with them."

......

There are constant disputes outside the Han Dynasty, and Anhe City is thriving. Today is the three-day judgment day for scientific research results. Princess and Lu Heyue became the judges of the first Youying Award for Scientific Research.

The review site was in the back mountain. A greenhouse was built on the sports field to shelter from the wind and rain, which could sit down for more than 200 people. The people who could sit in the greenhouse on the first day were all those who made outstanding contributions to the Han Dynasty, including students, craftsmen, guards, and some officials.

The people from the Si and Hanguo Newspaper sat on the left side of the stage. Both were to record the birth of some excellent works. Maybe there were inventions that had a significant impact on the Hanguo.

After Uesugi Yuying's passionate speech, he rang the bronze bell. The first person to go on stage was Lu's junior brother, who was strictly considered one of Uesugi Yuying's students.

He was wearing clothes from Jiangxi Academy, with the words "Ming" embroidered on the clothes, with a collapsed nose and small eyes. He looked a little cowardly. He was stared at by more than two hundred pairs of eyes, and his sideburns were left with sweat.

After saluting the princess, he turned around and walked to the 50-centimeter-high jade rectangle, which was prepared by the Han Dynasty. It was a luxury to make pure jade.

A wooden box was placed on the jade platform. He took a deep breath. The audience below became anxious, "Brother Chun, stop moji, hurry up! Everyone is asleep!" The person who spoke was a familiar friend at first glance.

There was a burst of laughter below, and Brother Chun glared at his friend, and the laughter dispelled the tension. He raised the copper-yellow object in the wooden box, a flat-length copper block about twenty centimeters long.

"Everyone, during the tribe period, the king announced that the tribe had opened up private ownership. We had our own finances, but our own things would be stolen. The whole family went out to work, and the family's finances were not safe. So I joined hands with the three people from the craftsman Academy and made this thing in three months. The king personally named it - Lock!"

In fact, the wooden lock was invented by Lu two years ago, but the wooden lock did not work much. The humans in this era were very strong, and smashing a wooden lock with one punch was not a problem. In addition, there were not many people at that time.

This year, the Ministry of Justice announced that the number of criminals is increasing, and the birth of the lock is natural. The three people successfully developed the three-ring lock based on the wooden lock and Lu's guidance.

The bronze system is just the beginning, and there will be iron locks at the latest next year. The locks will protect the safety of the private property of the people of the Han Kingdom.

Brother Chun locked the wooden box with the copper lock in his hand and opened it with the key. The wooden box was transferred to Uesugi Youying's hand. She failed to try to open the copper lock. She opened it after using the key, and handed it to Yue again. Yue tried it but failed and passed it to the person below.

Everyone took turns to try it and found that it was indeed difficult to break it. "Crack!!" Until a guard was breaking the copper lock with brute force, the whole audience suddenly became quiet.

The guard commander slapped him on the back of the head: "This is an experimental product, only you can! What can you do with such great strength!"

"Puchi!" Uesugi Youying couldn't help laughing, and laughter broke out in the greenhouse. Brother Chun quickly explained loudly, "Don't worry, everyone, this is just a copper, and there will be iron locks in the future. At that time, except for General Zhanhu, no one could open the iron lock with bare hands!"

"Ha ha ha ha!"

Someone still raised a question: "This iron lock cannot withstand the sword and axe when it is strong, and the meaning is as great as imagined."

When the people from the Crafts Academy saw that it was a student from the academy, they immediately began to refute: "That's safer than tying the door with a rope. This is an improvement and will be improved in the future!"

"That's better to improve the quality of the people!"

"You students like to say that this is the process of the birth of tools!"

The two sides argued and were soon stopped by Yue, "This is a scientific research meeting, everyone is quiet and don't abide by the rules!"

Uesugi Yuying cleared her throat: "Now we start rating, there are three scores in total, innovation score, practical score, and development score! (Ten system)"

The three of them discussed for a while, and each of them gave their own scores. Uesugi Yuying, Yue and Lu's innovation scores are: 5, 6, 6, and the overall score is 5.3.

Brother Chun can understand the reason why innovation score is so low. Not to mention the wooden lock, the key idea of ​​the three-spring lock is still provided by Lu, so he can still accept it.
Chapter completed!
