In her previous life, Cheng Ziyu had the idea of using pottery for military supplies.

At that time, she wrapped gunpowder in special pottery and designed it into a powerful thunderbolt.

Thunderbolts, ideal for ranged attacks. It can be thrown, it can be thrown, just let the special clay bottle reach the enemy's position, and the clay shell will explode when it shatters......

In night battles, it is especially effective to attack enemy torches with thunderbolts.

In water warfare, the damage caused by a thunderbolt to an opposing ship is even greater. If a wooden ship is blown up, the consequences will be fatal.

The idea stemmed from a small mistake in her previous life.

After becoming Princess An, she did her best to help Zhu Changan win the heir. After racking her heart, she thought of the combination of gunpowder and pottery early on.

She knew Zhu Changan's ambitions, and she originally wanted to give the thunderbolt as a surprise to a man as a gift. But Fengyun said that change will change, her gift was not sent, but she only used the gift as a last resort to blackmail and manipulate him.

At the end of the previous life, she gave Li Chun the blueprint of the thunderbolt clay shell.

In this life, she had a plan for the drawings of the thunderbolt clay shell early on.

In fact, according to her original plan, she started with the big gift today, reflecting the value of her and the Cheng family in front of the emperor as much as possible, and linking herself with the court as much as possible.

Just in case, if the goal is not achieved, then the thunderbolt will be her biggest trump card, and the emperor will definitely be interested.

Since she has decided to climb higher than in her previous life, and since she has decided to get the support of the emperor with all her might, then she must not only have a great reputation, but it is best to be inseparable from the court or the army.

As long as she grasps the secret technique in her hands, as long as she and her family have use value, even if the emperor is changed, then the consequences will not be too bad.

If she can become an arms dealer, a military businessman, then as long as the court does not fall, the value of her and the Cheng family will always be there.

However, the situation was clearly even better than she expected.

The ace didn't shoot, she had already got what she wanted the most!

At this moment, several generals were actually interested in a casual suggestion she had just made, and seriously discussed the feasibility.

The emperor was happy today, and seeing the warm atmosphere, he smiled so that several generals had time to explore the idea of using pottery as a terrain guide with the Cheng family's grandchildren and grandchildren......

Cheng Ziyu was ecstatic. The Emperor opened this mouth, which meant that her improvisation just now was not impossible. As long as the design is reasonable, she really has the possibility of becoming a military partner!

In this way, even if the pottery shell guide is not feasible, she will be able to throw the pottery shell design and recipe of the thunderbolt in time and time in the future, then, it will be enough to preserve the family.

The meeting part of the banquet continued, and with Cheng Jiazhuyu in front, naturally there was no big gift that made the emperor's eyes shine.

In this way, the Cheng family became the biggest beneficiary of the Yangzhou banquet in addition to the main family.

Cheng Ziyu breathed a sigh of relief, her hard work for many days was finally in vain. Judging by the emperor's statement at the moment, this big tree should be leaning on.

At this moment, she subconsciously looked for Li Chun's whereabouts.

didn't find Li Chun, but she noticed the yin owl eyes from Zhu Changan.

She didn't avoid it, but looked straight up, and then the corners of her mouth pulled up slightly.

Zhu Changan obviously didn't expect to face such a smile, so he was stunned for a moment, and then frowned and swallowed the wine in his hand......

When a vicious look came from Wen Lan's direction again, Cheng Ziyu glanced at Zhu Chang'an slightly, leaving a smile to Wen Lan......

Wen Lan decided that Cheng Ziyu was provoking, and she hated her and wanted to crush her silver teeth......
