Great Zhou Tianzi

In just half a year, Zhaocheng has changed a lot. Although Ji Jie had expected such a change when he came back when he left, he was still surprised when he saw it with his own eyes.

When the city wall was first built, there was room for expansion, but now it is taller and wider, and there are many turrets and gate towers. The soldiers standing behind the crenels are all wearing bright fine iron armor, holding shining weapons, behind them. It's a trebuchet and a bed crossbow.

Such a city is no less than the capitals of the Seven Kingdoms, and it is a truly grand pass.

The patrol team in charge of public security in the city is very different from the regular army in terms of clothing and equipment. They wear hard leather armor and carry wild goose feather swords at their waists, patrolling the streets day and night to ensure absolute safety in the city.

When Ji Jie and his party appeared at the north gate, the gatekeeper was stunned for a moment, then he quickly rubbed his eyes, and after confirming that he read correctly, he shouted happily: "Your Majesty is back, everyone is quick to welcome you!"

With this shout, the entire north gate was shaken, and the soldiers and civilians lined up to welcome them.

In the days when he was away, the battle reports were sent back continuously, and after each victory, the city would be very lively.

Rou Yue didn't expect that Ji Jie had such a good popularity, and was also deeply loved by the common people and the army.

The three girls received the news and went to the gate of the city to welcome them together.

Looking at the three beautiful girls, Ji Jie swept away the exhaustion of the past few days, jumped off the horse and hugged them in his arms, muttering: "You miss me..."

Ji Xueling turned to Rouyue who was still on the horse, and said, "Who is she? I remember that sister Ji Lin looks like this, right? Tell me honestly, where did you trick a girl over here?"

"That's right, with Sister Lin watching, you can still find other girls. It seems that Sister Lin has given us a lot of trust!" Sima Xueran said.

"Yeah, she looks better than Sister Lin. She should be a Hun with pure blood. Brother Jie, come on!" Zhao Qian feared that the world would not be chaotic.

"Don't talk nonsense, she is the princess of the Huns!" Ji Jie described it more and more darkly: "Didn't Xiong Kui send a Hun child over a while ago, and that is her brother. This is my wooing strategy, only the Huns If we don't make trouble in the back, we will have a chance to deal with the seven countries of the Central Plains, hehe!"

The three women didn't believe these lies at all, but they didn't expose him in front of so many people.

The first thing to do when entering the city is to listen to the summary report of the three women. He has been away for almost half a year. Although he can receive a written report every month, how can it be compared with hearing it with his own ears.

After half a year of development, the number of residents in Zhaocheng has increased by [-]%, and the number of soldiers has increased by [-]%. Moreover, from the beginning of the recruit training, they use the latest weapons.

Regarding the new weapons, Ji Jie has the most right to speak. He is the creator of the new weapons, and he is also the one who uses the most. He also knows the shortcomings exposed in the use.

There are two biggest disadvantages of the thunderbolt and the sky-shattering cannon. One is that the explosive power of the gunpowder is limited, and the gunpowder is very susceptible to moisture and cannot be effective in rainy weather; Before launching, the launcher subjectively judges the length of the wire, which will cause two consequences, either it is too long, and it will explode before it hits the ground, or it is too short, and it will explode before flying to the enemy's head.

Another point is that it has been more than half a year since the appearance of the new weapon, and it has been used in actual combat many times. It is impossible to keep it as a secret. It is estimated that the Seven Kingdoms have sent spies long ago. To inquire.

The formula of gunpowder is actually very simple, and ordinary alchemists can figure it out. Once they research it, Da Zhou has no advantage at all.

Ji Jie started to improve the black powder based on the attitude of what others do not have, what others have, and what others can change. Three steps is to expand the lethality of the two weapons.

After Rouyue drove to Zhaocheng, she often went to find her younger brother A Chi, so she didn't pester Ji Jie every day, and he was able to do research in his spare time.

From the moment Zhao Qian saw Xuechan, she fell in love with that little animal and studied it all day long.This guy Xuechan is cheap, no matter how Zhao Qian treats him, he is very cooperative, if Ji Jie didn't stop him, the little girl would have ripped him open.

With his unremitting efforts, the research quickly achieved results, and two new types of gunpowder were obtained.

One is to grind various materials very finely according to the original formula, spray the hide glue that has been boiled overnight on it by spraying method, and then make granular gunpowder. This kind of gunpowder overcomes fear The disadvantage of tide is easier to store and transport.

The second is yellow high-explosive powder, whose explosive power is three times that of black powder. Ji Jie installed such explosives in thunderbolt bombs engraved with prefabricated fragments. Lethality.

Then came the research and development of the fuze. He knocked the propellant into a thin iron tube, and used the principle of friction to generate sparks to ignite the propellant. It took about five seconds for the propellant to burn from one end of the iron tube to the other, and then ignite the inside Dynamite, the thunderbolt at this time is close to the embryonic form of the modern grenade.

The development of the fuze of the sky-shattering cannon was a bit troublesome, but it was still successfully solved by Ji Jie. He drilled six small holes in the projectile body, and inserted a special fuze before firing the projectile, so as to ensure that no matter which part of the sphere hits the ground, can be detonated.

In this way, the shortcomings of the new weapons were resolved. Ji Jie gave an order, and Ou Ming's forging supervisor began to make full efforts, and another part of the staff was allocated to continue the production of old weapons.

Then, at the same time, Ji Jie played a banner in the Seven Kingdoms, selling new weapons that he had already eliminated.

The Seven Kingdoms are worrying that they will not be able to obtain research results in a short period of time. After hearing the news, everyone is excited, especially Zhao Jun and Han Jun who have suffered from this. The monarchs of the two countries immediately ordered to send special personnel to come City to discuss the matter.

It’s no problem if you want to buy, my brother’s things are for sale, but apart from the fact that there is no credit, there is also a need to sign a commercial and non-aggression treaty with Da Zhou.

"Your Majesty, if we sell them everything, what if they turn around and beat us?" Ji Jian asked out his worries.

Ji Jie waved his hand and said, "It's enough that they are willing to fight us to the end. Do you think we will have nothing if we don't sell it to them? Instead of letting people figure out how to make it, it's better to sell it to them directly. As long as they don't master it The production method depends on us, and it’s too late to flatter, so how can we fight each other!"

"Your Majesty is right!"

Moreover, it is unknown how long it will take for the troops of the Seven Kingdoms who are accustomed to the old-style combat to adapt to the new style of play.
