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

Qinglongfang, the royal family's house.

Wang Renbiao stuffed a note into a small bamboo tube, then handed it to Leng Yuyao, and solemnly explained.

"Yes, Childe~!"

Leng Yuyao took it with both hands, and seeing that Wang Renbiao had no other orders, she took the secret letter and turned around and went out.

Around 3000 B.C., the ancient Egyptians began to use pigeons to deliver letters. China is also an ancient pigeon breeding country, during the Sui and Tang dynasties, in Guangzhou and other places in the south, pigeons have begun to be used to transmit letters.

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

Pigeons are sensitive to the Earth's magnetic field and are particularly homely, which is an innate strength. But to become a carrier pigeon, it's all about training. The fundamental purpose of raising carrier pigeons is to fly, race and use. In order to obtain the ideal carrier pigeon, in addition to careful breeding and scientific breeding management, the most important thing is training.

The training of carrier pigeons is very complicated, must start from the young pigeons, from simple to complex, from near to far, from day to night, from basic training to professional training, so an ideal carrier pigeon, its "training cost is very high, even if it is a rich and noble family message, generally only urgent letters will use carrier pigeons, because carrier pigeons will encounter accidents on the road!"

"Whew~! I hope my father's side will respond in time! Now that the cooperation between the Wang and Li families is about to be in full swing, it can't go wrong at this critical time~! ”

After seeing Leng Yuyao go out, Yan Shaoning looked out of the door with his hands in his hands and muttered to himself.

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

At the same time, almost half of the officials of Jingzhao Mansion scattered out of the city with Duguxin's forbidden army. To a certain extent, Jingzhao Mansion's current action not only has a certain risk, but also has a trace of unusual meaning in the action itself.

Since the founding of the Tang Dynasty, there has been almost no head-on conflict between the imperial court and Wulin, on the one hand, the strength of the Jianghu sect is very weak at this time, as long as there is no deliberate thing that is not long-sighted, the imperial court will not take those sects in its eyes.

Of course, the absolute disparity in strength has also made the large and small sects on the rivers and lakes have been in a decent and law-abiding manner in recent years, and no one dares to jump out against the imperial court, let alone assassinate the imperial court.

I have to say that the man in black who assassinated Li Zexuan was a first-class bird this time, and he was a first-of-the-line bird who was not pleasing twice in the martial arts and the imperial court.

Although the imperial court is not afraid of these martial arts people, the ordinary officials of Jingzhao Mansion are still quite afraid, so Huafu Yin specially invited Dugu Xin and asked him to lead the forbidden army to help.

Anyway, Li Er had also said before that he would let Dugu Xin assist him, such a powerful help, no need for nothing~!

As soon as Dugu Xin was dispatched, Li Er's side would naturally receive the news.

After all, Li Er is the absolute controller of all the armies of the Tang Dynasty, and the transfer of the forbidden army must be approved by him!

"Hmph~! Seven Cultivation Sect~? Snake Spirit Mountain~? What a big dog guts~! ”

Li Er leaned on the imperial case, supported his chin with his hand, and said angrily.

In front of him, there was a secret fold of Hua Wenjie's table.

"No matter who the head of these seven cultivation sects is, dare to challenge the majesty of the imperial court, and don't give me an explanation, I will encircle and suppress your sect~!"

Li Er closed the fold and thought coldly in his heart.

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

"Huh~? What is this gray thing~? You actually use it to build a wall~? ”

On Yunshan, Li Taigang commanded his team to bring back a batch of wood, but when he saw that the usual yellow glutinous rice mortar was gone, replaced by a gray mortar that he had never seen before, and the workers were still using this thing to build walls, he couldn't help muttering to himself.

"This is the latest cement developed in the workshop, which is specially designed to replace glutinous rice mortar! It is said that once this thing solidifies, it is more reliable than glutinous rice mortar! And this thing can also be brushed on the surface of the wall and the surface of the road, forming a flat and hard shell! ”

Yan Shaoning, who was also observing the cement mortar on the side, came over and said at this time.

"It's really that amazing~? But I think this thing is just a lump of gray mud, why is it not as powerful as Shaoning said~! ”

Li Tai's eyes widened and he said incredulously.

"Hmm...... I've also heard of this, as for whether it's really so magical, I'll know tomorrow~! ”

Yan Shaoning frowned and said.

In fact, he himself is skeptical of these.

"Heh~! Then wait until tomorrow to see it~! ”

Li Tai looked at it for a moment, then shook his head and said.

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

Following.

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

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

Mainly because Li Zexuan started in Yunshan and sent all the tasks to the construction site, he rarely went to the construction site, for his lazy urine, Li Tai could only curse him in countless small circles in his heart.

Climb to the top of Yunshan Mountain along the mountain road, and when you look at it, you will see that not far from the mountain gate, there are several cement walls that are two people high, and the ground around them is also gray cement floor, and now that place has been surrounded by a circle of people.

Li Zexuan smiled and walked over there.

"Heh~! The road surface is hard and smooth, and it is estimated that even on a rainy day, it will not be affected at all! I didn't expect it~! This cement is so magical! ”

An old craftsman touched the road with his hand and admired with emotion on his face.

"Damn~! Xiao Xuan can't do anything else, it's still reliable to research new things~! Shaoning, this cement is really better than glutinous rice mortar~! Ha ha~! This cement floor is good~! Smoother than bluestone pavement! No, no, no~! The king's palace will also have to use cement to smooth the road surface in the future~! ”

Li Tai touched it here, pressed it there, and then jumped up and patted Yan Shaoning's shoulder and laughed.

As for why you want to jump up, cough cough, of course, it's because of height, this little fat man has grown up since he was a child, he just eats and doesn't exercise, and his horizontal development is too powerful, and he basically doesn't develop much vertically.

As soon as Li Zexuan walked to the periphery of the crowd, he heard the little fat man's words arranging himself, he couldn't help but have a dark face, and quickly stepped forward and slapped Li Tai on the back of the head, and said:

"What do you mean by something else~? Qingque, you come to tell the teacher, where is the teacher~? ”

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