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

Chapter 757: The rapidly developing southern territory, intrigue begins in the backyard!

The troop mobilization under Gao Yao was originally much higher than that of other princes. With complete roads and systematic training, the princes could basically reach the Southern Border Army within seven days, which would take ten days to march. Now, as long as the enemy army was within the range of Gao Yao's built roads, it would only take five days to reach Gao Yao, which would take ten days to march.

This is definitely a great advantage in war, and this is just one of the functions of rubber. Natural rubber has strong elasticity and good insulation, and is waterproof, airtight, tensile, wear-resistant, and has good plasticity. This can be used in many aspects now.

The first point is about ships and medical treatment. In ancient times, the death and injury rate was very high when treating sword and gun wounds, especially on the battlefield. The most important point was the problem of wound infection.

Not only is the wound infected when injured, but more importantly, it is also easy to get infected during treatment. In this regard, as long as rubber is heated and made into gloves, it can effectively ensure the degree of infection during treatment. In addition, Gao Yao is now able to produce high-concentration distilled liquor, which can also achieve a certain effect on sterilization and disinfection after heating. Combined with Gao Yao's guidance, the mortality rate after injury can be reduced by at least 10% again.

Don't underestimate this small 10%. In fact, in a battlefield with tens of thousands of people, a battle can save at least dozens of lives.

The biggest improvement is in ships. Why were there so few ships sailing in ancient times? Even the ships that Gaoyao can produce now are very limited, and they need to be maintained at all times. In fact, the cost is very high.

The most critical issue here is the material. If a ship wants to sail on the sea, it must consider not only the sturdiness, but also the water resistance and sealing of the tree. When rubber is mixed with a certain proportion of morning glory juice, it can achieve a very good sealing effect, isolating air and moisture very well.

This not only increases the firmness of the hull, but also greatly increases the service life of the ship and its safety. This not only saves Gaoyao a lot of money, but more importantly, it saves Gaoyao from losing a lot of lives.

The navy established by Gao Yao actually suffered the greatest losses before the war. After all, the sea does not recognize people and can turn against them at any time. If you fall into a river, there is a chance of survival, but if you fall into the sea, you are almost certain to die.

One of the main reasons for this is that there are some unexpected situations with the ships, which has led to a lot of losses. This is also a necessary process. Even if Gao Yao has the technology to cast ships, technology is technology. Gao Yao cannot watch every ship go to sea, nor can he check every detail.

Moreover, many of the techniques that Gao Yao has mastered do not require materials that do not exist in this era, so he needs to find alternative items or materials, which requires experiments. The cost of such experiments could be as low as a few lives or as high as dozens of lives.

During the time that Gao Yao was away from home, a turbulent undercurrent quietly arose in the backyard of the mansion.

The new woman, Qi Ji, successfully aroused Yu Shu's jealousy with her unique charm and means. Yu Shu was already arrogant, and now facing the appearance of Qi Ji, she was even more dissatisfied, so she took targeted actions against Qi Ji in many things.

Unexpectedly, Lu Zhi cleverly drew Concubine Qi to her side. These two enemies, originally from different worlds, now unexpectedly stood on the same front. Concubine Qi was obviously an extremely smart woman. She knew that her arrival had caused a certain degree of hostility, so she had always been very low-key and did not fight or compete. Even after joining Lu Zhi's side, she just hoped to avoid being targeted in the backyard.

This low-key strategy is exactly what makes Concubine Qi outstanding. She knows that in this complex environment, being too ostentatious will only bring more trouble to herself. Therefore, she chose a seemingly yielding approach, but in fact it was a retreat to advance and protect herself.

The reason why Lv Zhi wanted to win over Concubine Qi was of course her own. She hoped to use Concubine Qi's power to help her regain her dominant position in the mansion. After all, Lv Zhi's position in this family was once very important, but Yu Shu now puts a lot of pressure on her. By forming an alliance with Concubine Qi, Lv Zhi might be able to strengthen her own strength and re-establish her authority.

Not only that, Lu Zhi's sister Lu Su and Xiao Yue and others began to get a little restless when they saw Lu Zhi and Qi Ji's alliance. They may have realized that the power struggle in the backyard was gradually escalating, and they also needed to find their own position in this game.

Before Gao Yao came back, a piece of news had already begun to spread, that is, Xianyang had been captured and the court might move the capital at any time. This matter was not only known to Lu Zhi and others, but many people in the court had already begun to spread it.

Once he went to Xianyang, Gao Yao would definitely become the king, and after becoming the king, Gao Yao would definitely have the most important position next to him. This position was very critical, but neither Lu Zhi nor Yu Shu wanted to compete for it. Yu Shu did it because of her identity, an alien identity. Even if Gao Yao gave her more rights in the mansion, Yu Shu didn't need to compete for this identity alone.

As for Lü Zhi, there was almost no hope for her. Lü Gong's matter was only one of the reasons. Another key reason was that she was too capable and ambitious. In the feudal society, few men wanted their women to be too smart and too ambitious.

So both of them almost have their own goals of wanting to be promoted. Lu Zhi's side is Lu Su, and she only wants to find Qi Ji in the hope that Qi Ji can attract Yu Shu's attention, while Yu Shu wants to push Xiao Yue to the top.

But now both of them have weaknesses. Although Lu Su is good in other aspects, his political sensitivity is too low. To put it bluntly, he is just a little stupid.

Xiaoyue's weakness is that she is good in other aspects, but her temper is too weak, which is also her biggest shortcoming. Without a certain degree of majesty, she can never reach that position. Now Yu Shu and Lu Zhi are fighting for this point.

As the news of Gao Yao's return spread, Lü Zhi, Yu Shu and others had already been waiting in the courtyard of the Prime Minister's Mansion.
