Zhao Qi still had some headaches about the speed of building houses in Daqin, which could not be completed in a short time by stone stacking alone, many civilian houses were still adobe, and only the mansions of princes and generals and the walls of the inner city of the big city were made of stone.

Building materials only the most basic raw materials is the most fundamental reason for the backwardness of the construction industry in this era, if you want to fundamentally eliminate this state, unless you invent a new one, when it comes to economy and practicality are far beyond clay and stone materials, Zhao Qi can think of the simplest Portland cement.

If cement can be born in this era, it will definitely make a qualitative leap in the construction industry of this era, the production process of cement is not particularly cumbersome, only need to put clay and limestone together, add a small amount of silicon, aluminum, iron firing, now the biggest difficulty is that Daqin currently does not have too much iron ore and crushing stone method.

The extraction of limestone is a big problem, and there is no such thing as shells in Daqin, so the rock can only be ground for use, but with the current technology, it is simply difficult to crush the stone.

Of course, the construction of Daqin is not just about building a house, later generations will respect talents to strengthen the country, how can Daqin have no talents? There are enough military talents, Wang Jian and Meng Wu are really capable, as for the civilian officials, I can't think of anyone, Lu Buwei is an ambitious person, but he is an uncertain factor, and it is really not certain whether he will be killed by Yingzheng in the future.

What worries Zhao Qi the most is the people who robbed and killed him when Yingzheng returned to Xianyang, these people are definitely not simple, there are too many hidden disasters in the chaotic era of the Warring States, and the threats of other countries are all on the surface, and sooner or later they will be broken by him one by one, so there is no need to worry.

What really annoyed him was the assassins sent by those forces hidden in the shadows, after learning the art of assassination, Zhao Qi knew how terrible this technique was, and the bone shrinking skill in later martial arts novels really existed, in the face of such a person, it was difficult to guarantee that Ying Zheng could safely live until the world was unified.

Zhao Qi can also roughly guess the origin of these people, it is nothing more than a group whose interests have been disturbed by the war of the vassal states, and the sons of the Warring States Period are vertical and horizontal, and among these hundred families, the most dissatisfied with the princes and kings is the farmer.

The people take food as the sky, and the farmer's proposition is naturally thrifty, but this is contrary to the arrogant and lascivious life of the royal family, and the generation of Chen Sheng and Wu Guang who rebelled later are all from the peasant family, and even Liu Bang, a great yin man through the ages, is the product of the peasant family.

The royal family blocked the development of the peasant family, and their greatest wish was naturally to overthrow the royal family.

There are many peasant party members, and it is impossible to eradicate it, and all Zhao Qi can do is to develop Daqin into an unprecedented democratic state, so that the peasants will not have the heart to resist. Only in this way can these people who are always thinking of rebellion have nothing to hide.

The heroes of the green forest came out in troubled times, and there was no such person in China in later generations, because it was strong enough, and Zhao Qi also understood this truth, but how difficult it is to push a battered vassal state to a prosperous era, I am afraid that he alone will not be able to reach that height in his life, he needs talents, Yingzheng needs talents, and Daqin needs talents.

Talents are not only able to fight and read a lot, in addition to these, the carpenters around him and the head craftsmen who presided over the construction of the Zhao Mansion are all talents he needs, and the material construction depends on them.

Zhao Qi shook his hand, and a short sword slipped out of his sleeve, he looked at the sharp blade of the short sword, and his face could be reflected on the bright face, this is a standard hundred steel, this kind of building process is only available when Datang is the strongest, Zhao Qi really wants to see this person, maybe he is the same as himself, accidentally fell into the wormhole and crossed over.

After the old craftsman left, Zhao Qi thought a lot, and he didn't even notice that Meng Tian was coming. After Meng Tian came, he didn't bother when he saw him like this, and asked Hong Sanbao to prepare some food for him, and waited for him to come back to his senses while eating.

In ancient times, there was a saying that the university inquirer would fall into a state of meditation every once in a while, which was a bottleneck on the way to learning, and it was necessary to pass this level through meditation, once it passed, the mind reached a new height, and the last meditative state in life was in the twilight years, and after the past, he became a sage, a great Confucian, or even a saint.

Meng Tian thought that Zhao Qi had encountered a bottleneck at a young age, and he was surprised and envious, to be honest, when Zhao Qi first appeared, his attitude towards Zhao Qi was contemptuous, as a representative of the good children of Xianyang at that time, he naturally did not put the unknown people who had never heard of it in his eyes.

As Zhao Qi's reputation in Xianyang grew, Meng Tian's eyes began to be a little jealous, How could a little-known little kid He De suppress him, a genius who has been famous in Xianyang since he was a child? But he still chose to mingle with Zhao Qi with an excellent tutor.

After getting acquainted with it, he changed a lot, and he found that although this kid's speech sounded like nonsense, every word was well-founded, which he couldn't do. Now he only admires Zhao Qi, the eight-year-old boy began to realize for the first time in his life, he is much older than Zhao Qi, but there is still no improvement.

Meng Tian sighed and thought to himself: Maybe I really can't compare to this demonic young man, no matter what, it's all for Daqin, and it's not necessarily a bad thing.

The Meng family has been two generations of Qin generals, loyal and loyal, and when he arrives at Meng Tian, he must be the most loyal servant of Great Qin, and his elders have taught him to focus on Great Qin in everything since he was a child, he only needs to know that Zhao Qi is a native of Qin, and he can only be a native of Qin!

Hong Sanbao didn't know as much as Meng Tian, he wanted to wake up Zhao Qi, but was stopped by Meng Tian, seeing Meng Tian shaking his head, Hong Sanbao didn't stretch out his hand again, and quietly accompanied Meng Tian with doubts and waited for Zhao Qi to wake up.

Zhao Qi sat for two hours, it was already late at night, there was no moon in late November, the courtyard was silent, only the windows in the lobby were still lit.

The wick of the oil lamp made a "zig" sound, interrupting Zhao Qi's thoughts, he stretched his waist, and at a glance saw Meng Tian who was sitting and Hong Sanbao who was napping next to him.

Before Zhao Qi could ask, Meng Tian took the lead and said, "Congratulations to my brother for taking a step forward in his knowledge."

"What are you doing here?" Although Zhao Qi didn't understand what Meng Tian meant, he still asked a question that he was more concerned about, and the moment he saw Meng Tian, he had a faint bad premonition in his heart.

Sure enough, Meng Tian showed a shyness and said politely: "I wonder if my brother still remembers promising his grandfather to train soldiers for my Meng family?"

Grass your grandma's Mengtian! Zhao Qi greeted the ancestors of the Meng family in his heart, Lao Tzu couldn't hide it, Meng Tian, this kid dragged words with himself, this nothing good!
