Liu Xiu left the state pastoral mansion, and his heart was relieved.

Liu Cong's character, he knows it well.

Liu Cong's personality has many similarities with Liu Biao, he is self-righteous, self-righteous, and even more desperate to save face and suffer crimes. Liu Cong has a shortcoming, he is afraid of death, or he is timid.

Liu Xiu humiliated Liu Cong, but Liu Cong did not react in the end.

It's not that Liu Cong doesn't hate Liu Xiu, it's fear.

In Liu Cong's heart, he wished that Liu Xiu would die immediately, and he wished to kill Liu Xiu, but Liu Xiu's threat made Liu Cong dare not act rashly. Without nine percent certainty of killing Liu Xiu, Liu Cong will not do it easily.

And Liu Xiu's words are by no means a threat.

If Liu Cong used the means of assassination again, Liu Xiu would not mind letting Liu Cong die on the woman's belly, or die unexpectedly.

In terms of the means of killing, Liu Xiu has a lot of them.

Liu Xiu believes that in the future, Liu Cong will fall silent and dare not come out again.

And Liu Xiu also needs time to accumulate.

At present, Liu Xiu, with the support of the Pang family and the Huang family, has a certain amount of strength, but in Liu Xiu's view, this is a flower in the moon mirror in the water, which is not reliable at all, and must have his own strength. All this requires Liu Xiu to go down step by step.

The assassination is not just that.

Liu Xiu was waiting for the opportunity, and after he had enough strength, Liu Cong's assassination and Cai's assassination were liquidated together.

Out of the city, the carriage ran to Lumen Mountain.

Back on the mountain, Liu Xiu went to see Pang Degong before returning to his courtyard.

The rest of the day, everything was calm again.

Huang Yueying stayed in the Pang family all day long, taking care of Liu Xiu's daily life, and the relationship between the two grew by leaps and bounds.

Tired of being together all day long, Liu Xiu is no longer limited to such a simple thing as holding hands, the devil's claws stretched out to Huang Yueying, the kiss has been kissed, and the touch has been touched, only the last step is missing.

On this day, the two walked in the villa.

Liu Xiu asked, "Yueying, is there any problem with the production of Quyuan plow?"

Referring to the manufacturing matters, Huang Yueying was full of spirit and said excitedly: "I have figured out all the design drawings, and the production of Quyuan plough is in progress." Soon, it will be finished. ”

Liu Xiu nodded and said, "Once the production is completed, it must be kept secret, and the news must not be leaked." I will discuss this matter with your father and teacher before making a decision. ”

Huang Yueying smiled and replied, "Listen to you." ”

"Da!

Suddenly, the sound of footsteps came from the hurry of the two of them.

A handyman quickly ran over and said respectfully: "Miss Yueying, the craftsman said that the farm tools you made have been made now, please accept them." ”

"Okay, let them be brought to the courtyard. ”

Huang Yueying's face showed a trace of excitement.

After the miscellaneous servants retired, Liu Xiu immediately took Huang Yueying to meet Pang Degong and explained the situation of Quyuan Li.

After Pang Degong heard this, he immediately sent someone down the mountain to invite Huang Chengyan.

When Huang Chengyan arrived on the mountain, Qu Yuanli was already in the study.

Huang Chengyan looked at Pang Degong Liu Xiu and Huang Yueying, his eyes swept over Qu Yuanli again, and asked, "Pang Gong, you are in a hurry to call me up from the bottom of the mountain, is there anything wrong?"

Pang Degong pointed to the Quyuan plow and said, "The name of this farm tool on the ground is the Quyuan plow, which was made by Xiu'er and Yueying. Xiu'er said that the curved plough is lighter than the current straight plow, and it is also easy to turn and turn, and the operation is extremely flexible, and it can also save manpower and livestock. ”

"Oh, really?"

Huang Chengyan's eyes showed a look of surprise.

The straight plough has appeared since the Western Han Dynasty and has not changed for hundreds of years.

At the same time, the drawbacks of the straight plough have also emerged.

The efficiency is low, time-consuming and labor-intensive, and it wastes manpower and material resources, and the quality of the soil is not high......

The appearance of the quyuan plough must have set off a boom.

As the head of the family, and even more so the head of the family, Huang Chengyan understands the benefits that Quyuan plough can bring. Before, the cylinder car brought great benefits, but because it was handed over to Liu Biao, it could not operate.

The current curved plough has a huge space for operation.

Huang Chengyan stared at the Quyuan plow and said, "Well said, it's better to do it well, so let's arrange someone to try it immediately, use the straight plow and the Quyuan plow to plow the field at the same time, and see the effect." ”

Pang Degong smiled and said, "That's exactly what I mean." ”

Liu Xiu said: "Mr. Chengyan, teacher, I have already found two farmers. Now, just go down the hill and plough the fields. ”

"Okay, let's go down the mountain. ”

Pang Degong and Huang Chengyan nodded, and the two of them said they would do it, and they got up immediately.

The group left the house, took the peasants who had been waiting for a long time, and went straight down the mountain.

At the bottom of the mountain, Liu Xiu asked people to find two ploughing oxen, and then set up a straight plow and a curved plough respectively, and the peasants began to plow the land in an idle farmland.

"Moo!

The sound of the cow was heard in the field, and the ploughing ox slowly advanced.

The curved plough and the straight plough began to turn the earth forward.

Liu Xiu looked at the farmer driving the Quyuan plough and introduced: "Mr. Chengyan, teacher, you look at the Quyuan plow and the Quyuan plow, when the two kinds of ploughs plough the ground at the same time, after plowing, when the direction is reversed, there is a situation of flexibility. ”

"The plough is not flexible enough to turn, and a lot of time is wasted when turning. ”

"Compared with the straight plow, the curved plough is flexible and lightweight, and it will be much easier in terms of time and manpower. ”

"You see, when the zigzag plough is moving forward, the soil is turned very easily, and as the oxen advance, the soil in the field is turned up like a wave, and it falls on both sides. The straight plough is different, the straight plough advances, it takes too much power to plough the ox, in order to keep moving forward, wasting too much manpower and ox power. ”

"The time consumed by unilateral ploughing, the curved plow is shorter, and the straight plough is longer, which is the most intuitive. ”

Liu Xiu's eyes were confident, and he continued: "Compared with the straight plow, in the design of the Quyuan plow, Yueying and I have added plow comments and plow arrows. ”

"The depth of the plough is determined by the length of the plough arrow, which in turn governs the length of the plough and arrow. ”

"The plough can be moved back and forth, as long as the plough is pushed forward when ploughing the land, the ploughshare can be ploughed downwards, and the ploughshare can be pulled back and the ploughshare is upward, and it can be shallow ploughing. ”

"Farmers can decide how deep or shallow their land can be cultivated according to different places. This is a great benefit. ”

"In addition, the plough wall not only breaks the soil, but also pushes the ploughed soil to one side, reducing the resistance of the plough forward. In this way, the time to plough the field is accelerated. ”

Liu Xiu was confident and calm, and said loudly: "Quyuan plough can definitely greatly improve the efficiency of cultivated land. My idea is that Quyuan Plough is operated by the Pang family and the Huang family together and is sold. ”

Pang Degong stroked his beard and said with a smile: "This suggestion is feasible." ”

Huang Chengyan said: "In terms of knowledge and external publicity, I'm afraid Xiu'er can't appear." Xiu'er, the Quyuan plough you designed was not handed over to Liu Jingzhou first, but directly handed over to us, once the publicity was designed by you, it would cause unnecessary trouble. ”

Liu Xiu said with a smile: "Mr. Chengyan is wrong, Qu Yuanli's external propaganda was designed by Yueying. ”

Huang Chengyan's eyes flashed, and he said, "This is a good suggestion." ”

Pound said fairly: "Xiu'er's proposal is very operational and reasonable, and the old man agrees." This matter, after the old man and Chengyan discussed, they will be arranged. ”

When Liu Xiu heard this, a smile appeared on his face.

It is true that Liu Xiu is a disciple of Pang Degong, and he saved Pang Tong's life, and his relationship with the Pang family is extraordinary. Moreover, Liu Xiu is Huang Chengyan's quasi-son-in-law.

However, in Liu Xiu's opinion, his relationship with the Pang family and the Huang family is not close enough.

The emergence of the quyuan plough is the binding of interests.

Liu Xiu was hidden behind the scenes, and the Pang family and the Huang family were united, so that Liu Xiu's Pang family and the Huang family were united, and the relationship became more solid
