After Guo Ziyi got Li Longji's consent, he turned around and went out, and soon, he was the only one who came over with a huge, dark thing, which was not light, and there was a muffled sound when he put it down.

"Your Majesty, please see, this is the treasure that Weichen dedicated to His Majesty." Guo Ziyi said with a serious face.

Li Longji looked at it curiously, touched it, and said with a puzzled expression: "Guo Qingjia, what's so strange about this thing?" ”

When he first looked at it, Li Longji thought it was a piece of unpolished black jade, because the surface looked rough, but it was a little cold to the touch, without the warm and moist characteristics of jade, the surface was thick and hard, and the material was not material, and it was like a stone that had not been beaten by thallium, and it did not show that it was precious in those places.

If it weren't for the fact that the person who recommended it was Gao Lishi, and the person who offered the treasure was Guo Ziyi, the champion of the new science and martial arts, Li Longji would have thought that this was a prank to bully the king.

Guo Ziyi didn't dare to sell Guanzi, and told the ins and outs of this cement column head, and when he talked about the back, he said excitedly: "Your Majesty, Weichen asked the third brother, that is, General Zheng, he said that the cost of these cements is very low, but the effect is excellent, not afraid of sun and rain, fire and watering, strong and durable, Your Majesty, think about it, if this new material is used as a border defense, it will be very effective." ”

When others see cement, what they think is magical, and Guo Ziyi immediately realized the use of cement in the military, just imagine, if the speed is fast, you can build a castle that others have only built for decades in a few months, the project is fast, the cost is low, and it is extremely strong, and it is simply an artifact in defense.

It is no exaggeration to say that with cement, Datang's defense capability can be increased by several levels in a short period of time.

Li Longji is also a smart person, and when he heard this, he immediately asked, "Is it really so magical?" ”

"Weichen didn't dare to bully the king, knowing that this was a bit incomprehensible, he specially brought the sample."

Guo Ziyi talked and did things, always thought twice, asked Zheng Peng for a sample, so that he could go back to research, the more he studied along the way, the more excited he became, and finally pulled the horse's head and did not return home, and went straight back to Beijing to present a treasure to Li Longji.

Li Longji didn't speak, just glanced at Gao Lishi.

Colliers replied and shouted, "Someone! ”

An order was given, two imperial guards stepped forward to listen to the order, Gao Lishi casually pulled out a horizontal knife from the waist of a guard, raised it and looked at it, the blade flashed with cold light, took a piece of paper from the imperial case, and swiped it lightly with the knife, and the paper was immediately cut in two.

Yes, very sharp, Gao Lishi nodded with satisfaction, raised the horizontal knife, looked at the cement column head, and slashed suddenly, only to hear the sound of "bang", and the horizontal knife was broken in response.

Li Longji stood up suddenly, looked at the broken knife, and then at the cement column, and said with some doubts: "This cement, is it really like what Guo Qingjia said, when it is soft like mud, when it is hard, it is like iron?" ”

"Wei Chen witnessed it with his own eyes, and he didn't dare to deceive His Majesty."

After a pause, Guo Ziyi said a little embarrassed: "Your Majesty, Weichen is walking too fast, he doesn't have a formula in his hand, and he doesn't understand the characteristics of cement. ”

Gao Lishi's eyes rolled, and he said with a smile: "Your Majesty, you can't blame Guo Zhuangyuan for this matter, Guo Zhuangyuan went back to his hometown to visit relatives, and went to visit his sworn brothers on the way, he couldn't stay too long, I heard that Guo Zhuangyuan stayed in Chang'an for a long time, and went to the Western Regions with General Zheng, and he hasn't gone back to visit his parents Gao Tang for several years, so it's better to let Guo Zhuangyuan go home to visit his relatives and send someone else." ”

"Makes sense" Li Longji nodded: "Guo Qing's family"

"Wechen is in"

"Go back and see your relatives, the holidays will be recalculated, I will reward you for one more month, and go home to reunite with your relatives, I will send someone else to verify this matter, and there will be another reward in the meantime."

"The emperor's grace is vast, and the ministers obey the order." Guo Ziyi said contentedly.

This matter, without merit and hard work, deepened the emperor's impression of himself, and he also took a month's vacation, which is not too good.

After Guo Ziyi retreated, Gao Lishi looked at the cement pillar on the ground and said, "Come on, carry this thing down and throw it away." ”

It's not a treasure or a jade, and it's useless to keep it, so naturally throw it away.

The two guards were about to carry it out, when Li Longji suddenly spoke: "Slow, put this treasure into the inner warehouse." ”

The cement column head is not a treasure, but if it is used properly, it can improve the offensive and defensive capabilities of Datang, and obtain more victories and land with it, which is more worthy of treasure than any treasure.

After the cement column head was lifted down, Gao Lishi said with some sighs: "This Zheng Peng is really talented, Leng might as well give you another surprise, God bless Datang." ”

"That's right, this Zheng Peng is really good at tossing, but the more he tosses, the more unexpected surprises he will give people, horse racing, and the prison army have verified, this time he went back to Yuancheng to build a house and marry a daughter-in-law, and let him play a new trick, hehe, Lux, just now you said that you sent someone else to Yuancheng for verification, do you want to make this errand?"

Li Long basically wanted Guo Ziyi to figure out this matter, firstly, he had a good relationship with Zheng Peng and was easy to talk to, and secondly, he was a martial champion and had experienced the battlefield firsthand, so he had a keen insight in this regard, and Gao Lishi suggested sending someone else with a sentence of "returning to his hometown to visit relatives".

"The old slave will only serve everyone, not other things, this is related to the affairs of the country, and the right people need to be sent."

No benefit can compare to the emperor's trust and dependence, and Gao Lishi is afraid that he will be taken advantage of by others to take his place when he is not there, so he is willing to leave easily.

"The right person? Lux which one do you say is suitable? ”

"Yu Shi Cui Yuan."

Li Longji was a little surprised and said, "He? The relationship between Cui Qing's family and Zheng Peng is a little unharmonious, is it appropriate for him to go? ”

"Your Majesty" Gao Lishi said with a smile: "Both of them are about to become sons-in-law, where is there anything inappropriate, Zheng Peng pleaded with His Majesty, regained his innocence for his wife who did not pass through the door at the sacrifice, and built a lot of construction in Yuancheng, it is said that Cui Yuan's request is the most suitable for him to go, Cui Yushi is experienced, whether the cement is useful or not, you can know it at a glance, and then the relationship between the two is delicate, so General Cui should inspect the future residence of the baby granddaughter in advance, so as to save Cui Yu and go on leave, which can not only save time, but also reflect everyone's compassion for the courtiers, Isn't it the best of both worlds? ”

"It's okay, these two are a little unpleasant with each other, so it's better for them to grind off some shuttle horns, so as not to have any demon moths when they get it." Li Longji nodded in agreement.

Colliers understood and said, "The old slave will arrange it." ”

......

"Lang Jun, drink tea." In a house in Chongren, Chang'an, an old man with gray hair respectfully put a cup of tea in front of Cui Yuan's desk.

"Well, put it down, Ren'an, what time is it?" Cui Yuan asked casually.

Ren'an is Cui Yuan's housekeeper in Chang'an Mansion, a talent selected from the family and slaves, who has been purposefully cultivated since he was a child, loyal to Cui Yuan, and helps Cui Yuan take care of many secret affairs, which has won Cui Yuan's trust.

"At two o'clock in the afternoon, Lang Jun, the meals in the kitchen are ready and ready to eat."

Cui Yuan yawned, as if he suddenly remembered something, and immediately asked, "When will Miss come back?" ”

Lu Shu entered Beijing to participate in the sacrifice and washed away the infamy of unchastity before marriage, Cui Yuan put down the big stone in his heart, at least Lu Shu and Boling Cui will not become the laughing stock of the world, but I didn't expect that after Lu Shu entered the palace, she was loved by Cui Zhaoyi, and often summoned her into the palace to chat, and sometimes spent the night in the palace.

Cui Zhaoyi is from the Cui family of Qinghe, and she is also a relative, and it is reasonable to care for her family.

Zhaoyi is the head of the nine concubines, coupled with the huge influence of the Qinghe Cui family, Cui Zhaoyi has a very high status in the harem, and is favored by Cui Zhaoyi, which is beneficial and harmless to Lu Shu, and Cui Yuan is also happy to let Lu Shu get close to Cui Zhao.

"There is a word in the palace that the young lady will return home tomorrow." Speaking of this, Ren'an said with a smile: "Cui Zhaoyi praises Miss a lot, rewards constantly, Miss has been in a good mood recently, she is always smiling, and she is either reading or being a female celebrity when she has time." ”

Cui Yuan shook his head a little helplessly and said: "If the female is not stayed, if you are forced to stay, you will become an enemy, this old saying is true." ”

Lu Shu's attitude has changed so much, and he doesn't need to ask Cui Yuan what the reason is, it is estimated that his granddaughter's heart will fly to Zheng Peng as soon as possible.

Ren An smiled on the side and didn't speak, the affairs of the master's family can't be discussed by any of his subordinates.

While he was talking, suddenly the window was knocked three times, the sound was two long and one short, and then he faintly heard a soft sound of "pop", Cui Yuan turned his head to look, and saw a hollowed-out half-cut bamboo tube in the corner of the wall, and there was an extra secret letter.

As the leader of the bad guys, Cui Yuan receives a lot of secret letters every day, and the way of receiving them is very unique, that is, to make a slide with hollowed out bamboo joints, and his subordinates throw them in a hidden place outside, and the secret letters will wander along the secret path to the study.

When Ren An saw the secret letter, he immediately took it and carefully placed it in front of Cui Yuan's case.

Cui Yuan looked at the secret mark of the bamboo tube, and when he saw the five-paw mark on the bamboo tube, his face suddenly became serious, this was the emperor's intention, and after seeing that the fire paint seal was not damaged, he carefully opened it and looked at it.

After reading it, he shook his head with a wry smile: "It's really a good errand, and it's okay, I just want to go to Yuancheng." ”

"Lang Jun? Yuan Cheng, this will is related to Zheng Xiaolangjun? Ren An couldn't help but ask in surprise.

Cui Yuan nodded and said, "This guy is really good at tossing, and repairing a house will also alarm Your Majesty." ”

Ren An smiled and said: "Zheng Xiaolangjun's matter, something is also a happy event, Langjun, when will you start?" ”

If you are a subordinate, you have to look at your face, Cui Yuan said that Zheng Peng was tossing, but his tone was relaxed and smiling, it was definitely not a bad thing, he felt like a loving elder laughing and scolding his juniors.

It's not a bad thing, Cui Yuan's identity is special, and the emperor personally ordered Cui Yuan to run away, which shows the degree of importance he attaches to in his heart, and there must be good news.

"Don't worry, deal with the matter at hand first, by the way, let the young lady pack up her things, and send her back to Boling by the way, a woman doesn't return home outside, it's not like words." Cui Yuan said.

This time I went to Weizhou, first, to complete the emperor's task, second, to see how Zheng Peng's house was prepared, and third, to personally escort my granddaughter home, killing three birds with one stone, Cui Yuan was very satisfied with this errand.

"Understood, the old slave will do it." Ren An said respectfully.
