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

At this time, Zhang Han did not rush to lead the central army. He sat steadily in the central army and commanded the army to advance slowly and orderly. This huge army of nearly 100,000 was cleverly divided into three parts: the vanguard, the central army, and the rear army. Among them, the 20,000 troops as the vanguard were mainly composed of fierce and brave cavalry, supplemented by agile infantry. They rushed into the deep canyon of Heilongkou like a violent storm.

Next came the 50,000 central troops led by Zhang Han himself. These 50,000 soldiers marched in neat and powerful steps, following the vanguard in front at a leisurely pace, and steadily advanced towards Heilongkou. At the same time, Zhang Han also continuously sent out smart and intelligent scouts to quickly disperse around and carefully explore the nearby terrain, enemy movements, possible traps, and other situations. Finally, the rear troops were stationed outside Heilongkou to avoid being attacked by the southern border army and to be able to defend this key position in time to protect them from being surrounded.

The reason why he was so cautious was that Zhang Han knew that the terrain here was extremely dangerous and complicated. Although the mysterious Yi Xiaochuan had issued the order to attack, Zhang Han did not blindly rush in. After all, the generals of the Qin Dynasty did not have a detailed map of the Black Dragon's Mouth, and knew very little about this area. In this case, in order to ensure the safety of the army and successfully complete the mission, the only wise choice was to remain highly vigilant and act cautiously.

At this time, in Gaoyao's residence in Nanhai County, the air seemed to freeze, and it was so hot that it was hard to breathe. It was the height of summer, and the unbearable heat was beyond people's imagination.

At this blazing moment, Gao Yao's study room was filled with a different kind of coolness. There were several people sitting together, each with a delicate porcelain bowl filled with crystal clear ice cubes in front of them.

Not only that, but the ice cubes are surrounded by a layer of delicate and smooth cream, like a blooming white lotus, exuding an alluring aroma. This unique combination is undoubtedly an ingenious "ice cream", which brings a rare coolness and sweetness.

The origin of these ice cubes is not easy. They are all made by deep well ice making. Although this ice making process is not too complicated, it requires a lot of effort. First, you need to dig a deep well with a sufficient depth, and the deeper you dig, the better the effect will be. Generally speaking, you need to dig to a depth of at least 20 meters.

The reason for this is that as the depth increases, the water pressure in the well will gradually increase. According to the principles of physics, the water at depth is often colder than the surface due to the strong water pressure. If the wellhead is tightly sealed and the water pressure is further increased, the water temperature will continue to drop until it reaches zero degrees, and eventually condense into ice.

In addition, there is a unique method - using the temperature difference between hot and cold to make cold drinks. The smoothies formed by this method are mainly known for their fineness and density; the other method is hard and solid ice cubes. These two methods have their own advantages, but their obvious shortcomings cannot be ignored: they require a lot of manpower and material resources, and the required capital expenditure is really high. Fortunately, today's high-tech has enough ability to bear these costs.

At this moment, in the spacious and bright main hall, Gao Yao sat firmly on the main seat, and below him sat Li Si, Wu She, Feng Quji and Xue Ye. In front of each person was a bowl of special cold drink prepared by Gao Yao himself. In this hot summer season, being able to enjoy such a cool and refreshing taste so easily made everyone present amazed and praised it.

As everyone was enjoying the rare coolness, they were all thinking about the same question: Why did Gao Yao summon them here? After all, before this, except Wu She, no one else knew that Gao Yao was in the county town.

When these people saw Gao Yao appear, their doubts instantly receded like a tide, replaced by a sudden realization. It was obvious that Gao Yao had carefully planned a grand and meticulous chess game.

"My lord, I really don't understand why you can be so calm in the face of such a tense situation. There is war going on in Guilin County right now, and the fighting is extremely fierce. This..." Finally, the impatient Xue Ye couldn't hold back his anxiety and broke the silence first. As a veteran general, he was always resolute and vigorous. In addition, he was younger and more energetic than others, so he naturally couldn't stand this unclear situation.

Facing Xue Ye's anxious questioning, Gao Yao just raised the corners of his mouth slightly, revealing a faint smile. Then, he slowly turned his gaze to Feng Quji, who had been standing silently by the side, and said calmly: "Master Feng, you should explain this matter to everyone."

As soon as Gao Yao finished speaking, Feng Quji's hand holding the teacup trembled slightly, and the cold drink in the bowl almost spilled out. From the moment he learned that he was going to Gao Yao's residence, until he saw Gao Yao's sudden return, Feng Quji knew that this matter was definitely not that simple. It was fine to call others, but if you called me, I was definitely not Gao Yao's confidant.

Regardless of whether Li Si was called, after all, he had met Li Si before, so he knew Li Si's situation here. However, he actually called Li Si this time. What was his intention? Was it to give him a warning and take the opportunity to hit him? Look at who Xue Ye is. He is the city defense officer of the county city, and it is worth mentioning that he is the general of the city defense camp of Nanhai County City! Such a position is not something that everyone can do. Only Gao Yao's confidant can take on the responsibility.

In addition, there was also Wu She, whom he had never met before. The fact that he was qualified to take a seat and taste such unique delicacies was enough to show how much Gao Yao valued him. At this moment, Feng Quji's mind was as clear as a mirror, and he knew that today's dinner was not simple. Sure enough, at this moment, Gao Yao asked directly without beating around the bush. Faced with this situation, Feng Quji couldn't help but murmured: The most critical issue at the moment is whether or not he should respond honestly? After a brief inner struggle, Feng Quji finally turned his gaze to Li Si, and then slowly spoke,
