The Yin-Yang Academy, which is not the largest number of people and does not occupy the largest area, still has a place that ranks among the various academic palaces, that is, high. In the Yin-Yang Academy, a tall building in the center makes it within a radius of dozens of miles. As long as someone passes by and looks at it, it is really too high. For this era, it is an unimaginable height.

This is a wooden tower with a height of nearly twenty feet. For the building materials at this time, this is almost the largest height that can be obtained.

In this tall building that can attract people to the world, there is also a person that can attract people to the world to the world. To be more precise, it is a woman: Dongjun Yanfei, the Yin-Yang Family.

This woman who appeared in Xianyang two years ago has become a little more calm after experiencing a series of setbacks. The girl who was stupid and ignorant at night in the Qin Palace has long disappeared. Now she is the helm of the Yin-Yang Snow Palace, and she is also the editor of the calendar and occupies a core position among the three major branches of the Yin-Yang Academy.

Of course, there is a fact that she will never admit, that is, she, a genius girl in astrology and editor of the future calendar of Qin, has no one under her command.

Compared with Yun Zhongjun, who is in charge of the Jin tribe who mainly engages in alchemy for the development of explosives, and Emperor Shun, who is in charge of the Earth tribe who mainly engages in Feng Shui for maps, she, the second person in the Yin-Yang family and the helmsman of the Yin-Yang Academy, is undoubtedly much more desolate. The only thing that can make her feel comforted is perhaps this unique tall building that belongs to her.

But even this tall building has something that makes her extremely unhappy. According to her original intention, this tall building will have a very beautiful name: Star Gazing Tower.

However, there are always people who like to go against her. Her longing seems so powerless in front of her other hands, because she is the owner of this place, and that person is the landlord of this place.

The poetic and picturesque Star Gazing Tower turned into a Star Piercing Tower under the man's hand.

In fact, whether it is stargazing or stargazing, it is just about the length and short, but there is no way to compare it. Everything can only be attributed to personal preferences.

But there is actually another reason for Yan Fei's dissatisfaction.

In this world, it is not only the night sky that has stars, but also the world. Who can tell this question clearly about the stars in the night sky or the stars in the world that the owner who wrote the name of this tall building?

But Dongjun Yanfei still noticed a deep malice from it. The evil in this malice is nothing else, but it is just the meaning of a prank.

"You did this just to make me unhappy. However, I was not fooled. I want to calm down and concentrate." Yan Fei, who was on the top floor and chatted with the mysterious starry sky all night, covered her heavier chest and said to herself.

However, the face of the woman who had just completed calmness and concentration became even more gloomy. The three-legged golden crow, which was hidden in the attic at the entrance of the Academy, saw a line of familiar frames.

"Why is he here again?" Yan Fei, who recognized who the frames belonged to, couldn't help but feel panic.

Calculate the time, it’s not time to collect debts today. Yan Fei, who ran to the railing and looked at the frame, murmured to herself.

Ying Zheng also knew that the Hundred War God Mechanical Crossbow is powerful, but the only one who can exert its maximum lethality is when it is used for the first time. After all, there are no invincible weapons, only invincible people. Once the enemy understands the characteristics of the Hundred War God Mechanical Crossbow and wants to maximize its lethality, it requires the cooperation of the enemy. When the decisive victory on the battlefield, the most unreliable thing is the cooperation of the enemy.

Therefore, he wanted to use these powerful weapons on the iron cavalry of the Zhao army, whose combat power was not inferior to that of the Qin army, and strive to defeat the Zhao army's resistance in one battle.

And not long ago, Xu Fu finally developed something that can be called explosives in this world.
