Mythical Qin: I, Gao Yao, will never be a eunuch!

And this is just the most basic benefit. Even if the food in the portable space cannot be reused, Gao Yao can use the special features of the space to directly plant many plants that do not exist in this era, and then directly convert these things into cash, Gao Yao can get huge benefits.

Compared to the improvement of force value, or giving some weapons, equipment and armor, it can be said that this portable space can be regarded as a treasure. It will be of great help to Gao Yao in the future. This also made Gao Yao, who was very depressed because he could not kill Yi Xiaochuan, feel much better.

The next morning, Gao Yao and his party were on the road again. At this time, Gao Yao and his party were less than ten miles away from the northern border. During this period, there were indeed some people who wanted to escape, but Gao Yao did not mean to be polite and chose to kill them directly. As they gradually approached the Great Wall that was being built, Gao Yao could not help but sigh in his heart.

Gao Yao had visited the Great Wall before the time travel, but at that time he just visited it as an ordinary tourist attraction. He climbed the Great Wall with great difficulty for the saying "He who has not visited the Great Wall is not a true man". However, now when he saw this great building being gradually built, Gao Yao deeply felt the great difficulty and hardship of building the Great Wall.

In this era, the Qin Dynasty had not yet mastered advanced technologies such as pulleys. Every brick was carried and stacked by countless laborers with their hands. They built this magnificent Great Wall bit by bit with their blood, sweat and life. Qin Shihuang made great efforts and sacrifices to build the Great Wall, and also bore the eternal infamy. But as a time traveler, Gao Yao knew the importance of the Great Wall to the country and the nation. It is not only a line of defense, but also a symbol of the perseverance of the Chinese nation.

From a historical perspective, Qin Shihuang's foresight and determination made the Great Wall a valuable asset for future generations. It protected the country's security, promoted cultural exchanges and integration, and laid a solid foundation for the prosperity of future generations. Therefore, Gao Yao was deeply moved and believed that Qin Shihuang's achievements were not only temporary glory, but also a feat of peace for all generations.

"Brother, there are about 500 cavalry troops approaching ahead."

"Um"

At this time, Erniu came to Gao Yao and reported the discovery ahead. Gao Yao did not delay and immediately rode forward, commanding his troops to form a defensive formation. This was basically equivalent to an instinctive formation trained on him. With the infantry as the center point, the corvées were protected in the middle, with cavalry on both sides. Gao Yao was the first to arrive at the front.

Soon, more than 500 cavalrymen from the opposite side came to within a hundred meters of Gao Yao. Gao Yao looked at their standard equipment and recognized that they were also Qin troops.

"Who is coming?"

"A thousand people from Sishui County were ordered to escort corvée laborers to the northern border."

While Gao Yao was talking, he took out a pair of bamboo slips from his arms and handed them to Erniu. Erniu did not waste any words and immediately handed the things to the other party. On the bamboo slips were the seal of the governor of Sishui County and the general situation of the matter, which was similar to a transfer order.

After the other party confirmed the above information, a man wearing a general's armor led several people to Gao Yao.

"Hutu, the Border Guard Captain"

"I, General Gao Yao, greet General Hu."

"That's not necessary. The corvées General Gao Yao brought here can be regarded as a solution to our urgent needs. A few days ago, the Rongdi came to plunder and killed many corvées. The construction period was also delayed a lot. If the construction period is repeatedly delayed, I will inevitably be punished."

"These are all my duties, I don't deserve your gratitude."

Relatively speaking, there is still enough respect for these soldiers stationed at the border. Although their positions may not be high, they are the ones who fight the Huns on the front line with real swords and guns.

"Hahahaha...Okay, that's great. General, follow me to set up camp first. After you get some rest, I'll write you a letter. How about that?"

"Here"

Although Gao Yao had made a lot of contributions, he still had to be honest and respectful to those who guarded the border. These people might not be much higher than Gao Yao in terms of position, but Gao Yao could not compare with them in terms of military merit and title.

The process Hutu mentioned was also a normal handover process. The laws of the Qin Dynasty were very strict, and the punishment for violation was also very severe. If the violation was minor, the offender would be dismissed from office and imprisoned, and if the violation was slightly more serious, the offender would be directly executed. This strict military order was to some extent the key reason why the Qin army was able to destroy the six kingdoms and then unify the world. Throughout history, it was one of the few troops that enforced the orders.

Soon, under the leadership of Hutu, Gao Yao and a thousand soldiers escorted these corvées to the vicinity of the Great Wall that was being built, counted the number of people and registered them, and then settled down to rest. After all, Gao Yao's soldiers had not rested along the way. After sending the people there, the mission was completed. The only thing left was to return to Sishui County, and the speed of returning would definitely be much faster.

Gao Yao also decided to take a rest here temporarily and set off again after getting supplies. Hu Tu also warmly entertained Gao Yao that night, but due to limited conditions, the so-called hospitality was just dried horse meat and some wine. Gao Yao could understand this.

Because the work of building the Great Wall in the north was done in sections, Hutu had only 3,000 soldiers under his command. On the one hand, they were responsible for preventing corvée from escaping, and on the other hand, they were responsible for preventing foreign tribes such as the Huns from taking the opportunity to plunder. However, due to the limited manpower, there were actually many positions to be guarded. Therefore, except for a small number of soldiers who were fixed at a certain position during the day, most of the Qin soldiers adopted a patrol system, which could maximize the effectiveness of these Qin soldiers.

The next morning, Gao Yao also came to the construction site of the Great Wall. Although Gao Yao was not an excellent student, he had attended university and high school and learned some science knowledge. He knew the simplest movable pulley and fixed pulley. Once these devices could be used, the speed of construction would at least double compared to now, and the number of people needed could be halved.

Although it is definitely unrealistic to use iron things in this era, on the one hand, the craftsmanship is not up to the standard, and on the other hand, it is far from being able to achieve mass production. However, it is possible to use wood. The disadvantage is that it is easy to be damaged. The advantage is that the things needed are not too difficult. If hundreds of carpenters are gathered together, the things made will be enough for tens of thousands of people to use, and the materials are easy to find. However, Gao Yao did not express his ideas directly. Even if it is a good thing, it still depends on the time. When to say it, when to do it, and to what extent it is all necessary to consider carefully.
