Otaku Engineer in Great Tang Dynasty

"Yao'er, Nuo, you immediately send this letter to my father with a flying pigeon!"

Qinglongfang, Wang Family Residence.

Wang Renbiao stuffed a piece of paper into a small bamboo tube, then handed it to Leng Yuyao, and solemnly confessed.

"Yes, son~!"

Leng Yuyao took it with both hands. Seeing that Wang Renbiao had no other instructions, she took the secret letter and turned and left.

Around 3000 BC, the ancient Egyptians began to pass letters with pigeons. China is also an ancient country for raising pigeons. During the Sui and Tang Dynasties, in southern Guangzhou and other places, pigeons were used to deliver letters.

Although the speed of this thing is many times faster than that of the post, it is not something ordinary people can afford.

Pigeons are very sensitive to the earth's magnetic field, and they are particularly fond of home, which is their inherent advantage. But to become a homing pigeon, the main thing is training. The fundamental purpose of raising homing pigeons is to fly, compete and use. In order to obtain the ideal homing pigeon, in addition to careful selection and scientific breeding and management, the most important thing is training.

The training of homing pigeons is very complicated. It must start from the young pigeons, from simple to complex, from near to far, from day to night, from basic training to professional training. Therefore, an ideal homing pigeon has a very high cost of training. Yes, even if it is a letter from the rich and the rich, usually only urgent letters will use the carrier pigeon, because the carrier pigeon will encounter accidents on the road!

"Huh~! I hope my father can respond in time! Now that the cooperation between Wang and Li is about to start in full swing, you can't go wrong at this critical time~!"

After watching Leng Yuyao go out, Yan Shaoning looked out the door with his hands folded and muttered to himself.

........................

At the same time, almost half of the government officials in Jingzhao Mansion were scattered out of the city with the imperial army of the Duguxin. To some extent, the current action of Jingzhao Mansion not only involves certain risks, but the action itself also carries a hint of unusual meaning.

Since the founding of the Tang Dynasty, there has been almost no direct conflict between the court and the martial arts. On the one hand, the Jianghu sect is very weak at this time. As long as there is no deliberate intention to engage in things, the court will not put those sects in its eyes.

Of course, the absolute disparity in strength has also made the big and small groups in the arena have been quite and law-abiding in recent years. No one dared to jump out and fight against the court, let alone assassinate the court officials.

I have to say that the man in black who assassinated Li Zexuan was regarded as an early bird this time, and he was an early bird in the martial arts and the imperial court.

Although the imperial court was not afraid of these martial artists, the ordinary yamen in Jingzhao Mansion were still quite afraid, so Washington Yin specially invited Duguxin to lead the Forbidden Army to help.

Anyway, Li Er once said that Duguxin should help him. Such a powerful assistance is unnecessary~!

As soon as Duguxin dispatches, Li Er will naturally receive news.

After all, Li Er is the absolute controller of all the troops of Datang, and the movement of the Forbidden Army must be approved by him!

"Huh~! Seven repairs~? Snake Lingshan~? What a darety person~!"

Li Erfu was on the imperial case, propped his chin with his hand, and said angrily.

In front of him, there was a secret book of Hua Wenjie.

"Regardless of the sacred head of the Seven Cultivation Sect, I dare to challenge the imperial court. If you don't give me a word, I will encircle your sect~!"

Li Er closed tightly, thinking coldly in his heart.

................................

"Huh~? What is this gray thing~? You actually use it to build walls~?"

On Yunshan, Li Taigang commanded his team to transport back a batch of wood, but saw that the usual yellow glutinous rice mortar was gone, replaced by a gray mortar he had never seen before, and the workers were still using it. He couldn't help muttering to himself in doubt as this thing was building a wall.

"This is the latest cement developed by the workshop to replace glutinous rice mortar! It is said that once this thing has solidified, it is more reliable than glutinous rice mortar! And it can be brushed on the surface of walls and roads to form a layer Flat and hard shell!"

Yan Shaoning, who was also observing the cement mortar, walked over and said.

"It's so amazing~? But I think this thing is just a pile of gray mud, how come it's not as powerful as you said, Shaoning~!"

Li Tai stared in disbelief.

"Hmm...I also heard about this. As for whether it is really such a miracle, I will know tomorrow~!"

Yan Shaoning frowned and said.

In fact, he himself is skeptical of these.

"Heh~! Then wait for tomorrow to see~!"

Li Taiton watched for a while, then shook his head and said.

...........................

The next day.

Li Zexuan also got up early, he had to go to Yunshan to see the actual effect and response of cement.

As for Li Tai's follower, he hasn't come here for several days, and goes to Yunshan alone every day.

The main reason is that Li Zexuan seldom went to the construction site after he started in Yunshan and dispatched all the tasks. For his lazy urination, Li Tai could only curse countless small circles in his heart. He ~www.ltnovel.com~ followed the mountain road to the top of Yunshan Mountain, and when he saw it, he saw that not far from the mountain gate, there stood these two-person-high concrete walls, and the surrounding ground was also gray concrete. , Now that place has been surrounded by people.

Li Zexuan smiled, then walked over there.

"Heh~! This road is hard and smooth. It is estimated that it will not be affected even in rainy days! I didn't expect it~! This cement is so amazing!"

An old craftsman touched the pavement with his hand and exclaimed with emotion.

"I rely on~! Xiaoxuan can’t do anything else, researching new things is still reliable~! Shaoning, this cement is really better than glutinous rice mortar~! Haha~! This cement floor is good~! It's flatter than the bluestone road. No way, no way~! This king's palace will have to use cement to level the road in the future~!"

Li Tai touched here, pressed there, then jumped up and patted Yan Shaoning's shoulder with a laugh.

As for why he jumped up, coughing and coughing, of course it was because of his height. This little fat man grew up, eating and not exercising. The horizontal development is too strong, and the vertical development is basically not much.

As soon as Li Zexuan walked to the outside of the crowd, he heard the little fat man arranging his own words. He couldn't help but his old face went dark. He quickly stepped forward and slapped Li Tai on the back of his head, saying:

"What's the meaning of nothing else~? Qingque, you come to talk to the teacher, why can't you be a teacher~?"

As a man, the most taboo thing is that others say that he can't do it. This already involves the dignity of a man. Li Zexuan is not willing to let this little fat man easily let go.
