In front of the Imperial City's dormitory, Tian Khan slowly came towards Zhenxiang.

"Li Zhenxiang, what did you do today to eat beautifully in Ben Khan?"

Suddenly, under the red carpet where Tian Khan's right foot was stepping, he suddenly felt a foreign object against his own foot.

This thing is hard and hard, but it can be stepped on with one foot, which makes the Khan stunned.

"Boom!"

A small bombing sound rang out, and a wisp of colored smoke rose from both sides of the red carpet.

This smoke is a multicolored color, rolling out of both sides of the carpet and then gathering into a ball, like a mushroom, its colorful color, so that the Khan is so happy.

"This ...... Why is it that such a general cloud rises under the red carpet on the ground? ”

Khan stroked the strange smoke with both hands, and wanted to grab a handful to play with, but although the smoke was colorful, it was ethereal and ethereal, untouchable, and it would dissipate under the blue sky in a moment.

"The day is auspicious, and this colorful light and smoke is the great gift that Zhenxiang gave to the Khan today."

"Colored smoke?"

Tian Khan was very puzzled, although this colored smoke was colorful and fragrant, but it was very ethereal, fleeting, and seemed to have no substantive use, how could it be a great gift for himself.

Zhenxiang looked at the Khan, but knew what was on the Khan's mind, so he walked down from the door and took out the small wooden box in a small pit dug under the red carpet.

"Khan, the sun is scorching outside the palace, please enter the palace, and Zhenxiang will talk to the Khan again."

……

Under the yellow case, Li Zhenxiang tinkered with a small box made by the maids yesterday, so happy.

"Zhenxiang, what is this?"

"This thing, my hometown calls it Earthquake Thunder!"

"Earthquake Thunder?"

In this way, Tian Khan took the small bamboo box with a blank face, so that he could investigate.

This box is made of a small bamboo tube, the barrel is connected with a bearing and a flip lid, the plate body is concave, and the inside is filled with water.

On the other side of the bearing, it is to wear out the bamboo tube and connect a small piece of green bamboo.

As long as the khan's feet touch the bamboo pieces outside the bamboo tube, it is a linkage bearing, knocking over the water in the bamboo tube, just sprinkled on the colorful medicine powder placed at the bottom of the barrel, so that the colorful light smoke is swaying up, and the mushroom cloud suddenly rises.

This girl, who was rejected for a date in her previous life, cried and mourned too much, and the trash can was overwhelmed by the weight of tissues and began to strike.

She was unceremonious, and her own research was to mature the principle of trash cans in her heart and repair one trash can after another.

This wooden box resembles a garbage can from another world, but the girl has slightly improved it, placing the trampling bamboo piece on top of the bamboo tube, and placing the inner flap of the bucket below.

"Such a small box, so wonderful, very good, in the future, you will make more of this little thing for Ben Khan, and you can have a good time when you are free."

She took the small box and placed it in the corner of the table: "Khan, such a bamboo box is not a toy thing, but a murderous weapon!" ”

"Murderous weapons?"

"This thing is a thunderbolt that shakes the sky, and its power is fierce, and it can destroy tens of thousands of elite soldiers."

"What, tens of thousands of elite soldiers?"

Suddenly, Tian Khan paused and looked at the small box, unexpectedly thinking that this small bamboo box could destroy thousands of troops.

"Because I just tried it with Tian Khan, I modified this thunder and used bamboo tube water as a thread primer, so that the medicine powder in the barrel reacted and produced thick smoke, but it did not have any lethal power.

And if it is in the northwest, the barrel is changed into an iron ball, and the powder is changed into gunpowder powder and buried in the open field outside the city in advance, just imagine, such a small soldier stepped on it, the gunpowder ignited, and the thunder was detonated, and its power was enough to kill the small soldiers and good horses who stopped within three meters.

If a few sharp pieces of iron are added to this thunderstorm, not only will there be no grass within three meters, but there will no longer be a single living thing within five meters.

Once this thunder is made, bury it on the ground outside the city hundreds, cover it with loess, and when the enemy's iron horse soldiers step over, the military field will be a mess, he will be less than the power of this thunder to destroy it, this battle, the North Han will win! ”

"Gunpowder?"

At the end of last year, he had heard that in a battle in the city of Li, Xibang, Dongqiu used a new type of weapon, which did not need to be wielded with knives and guns, but only needed to be ignited with a fire and thrown outward, which could collapse the enemy army, and its destructive power could be called terrifying.

According to this rumor, the name of this new type of weapon is called a powder bag.

These days, Tian Khan has been sending a meticulous to inquire about the production method of this gunpowder, has been unsuccessful, unexpectedly, today, Li Zhen actually put out the gunpowder pack, and also offered such a wonderful earth-shaking thunder.

In this way, he will no longer be invincible, and a thunderbolt can blow this thief into the ghost mansion, and he will never be able to live beyond his life.

Khan couldn't bear it, and asked Li Zhenxiang how to make this earth-shattering thunder.

Li Zhenxiang knew that this khan was interested, and he had read a Ming Dynasty military book boringly in his previous life, which recorded the principle of making mines from steel wheels and flint used by Qi Jiguang, but he didn't expect that this life could be used in the war in the northern cold.

Zhenxiang said that this thunder is to use steel wheels to ignite, first use iron to build a ball, and place a set of transmission system in the ball.

In this way, when the enemy stepped on the motive, the falling stone in the box fell, driving the steel wheel to rotate, and the flint violently rubbed into flames, detonating the thunder.

Immediately, Zhenxiang took out the schematic diagram of the earth-shattering thunder she had drawn and the detailed structure of each part from a wooden box and showed it to Khan.

Such a sketch exhibition, the parts on the map are beautifully painted, and the parts are closely connected with each other, in an orderly manner, so that the Khan of Heaven is amazed, such a precise drawing, where did Zhenxiang learn.

She smiled, just saying that the people from her hometown carry the wisdom of all the sages in ancient and modern times, and she just copied it step by step.

It's just that the process of such a thunder is cumbersome, and the girl said that she will not be able to make such a thunder by herself, but she wants the Khan to give an order to hand over this set of drawings to the engineer department who manufactures weapons, and use the best craftsmen of the Northern Cold to make the thunder as soon as possible, and at the same time make gunpowder bags.

"Okay, Zhenxiang, you have made a great contribution this time!"

Ma Gonggong was passed in, a holy decree was issued, and all craftsmen were mobilized throughout the country to make a special special incense: earth-shaking thunder.

Li Zhenxiang kowtowed, and then prepared to retire.

"Zhenxiang, where are you going?"

"Khan, the maidservant wants to ...... I want to sleep, I didn't close my eyes last night! ”

In this way, it amused Tian Khan again, no wonder when he saw the girl this morning, this girl's eyes seemed to be beaten, and it was very scary.

"Go, it's just that after waking up, this Ordnance Division can be supervised by you, so that they can survive and urge them to build the earth-shaking thunder as soon as possible, and He'er will defend the city with his life, and the group of small workers will not be allowed to slack off."

As soon as she left the door of the dormitory, the girl turned her back on the direction of her boudoir and ran straight to the Ordnance Division, supervising her work and creating thunder.
