In April in the northern land, when other flowers are still buds, the peach blossoms of Taoyuan Villa are blooming.

Mrs. Tai even said that this was a good sign, although she did not know that today was her eldest grandson, the day of the war!

Of course, Gu Xinyu also felt a burst of joy when she heard Mrs. Tai say this.

That's a good sign.

She gave the exercises to Wangcai, and sure enough, the Buddha was destined to be a person.

Wangcai was still lying on the couch, but the exercise was suspended by itself, and then spun rapidly, when Gu Xinyu's eyes were about to stare on the ground.

The exercise turned into a white beam of light, heading towards Wangcai's head.

After a few moments, the point of light vanished.

Then Wangcai happily told Gu Xinyu that this exercise, and the fragments left in his mind, had been integrated.

From now on, it can be cultivated.

After Gu Xinyu encouraged Wangcai, he walked out of the flower hall and pushed open the door of the house, there was a pear tree outside, at this time, it was normal, according to the original pace and law, little by little.

And then on a certain day, it blooms beautifully.

Xiuzhen's world is far away, she is just a mortal, she has no interest in their world, and she doesn't want to make herself their interest.

Gu Xinyu went to the valley where the fire bomb was studied.

Even if the man in black guarantees that he is safe, Gu Xinyu now feels that at any time, it may be the most dangerous to hand over his life to others to protect him.

She needs to be prepared to protect herself.

Grandpa Guo is here, as always, as if he has become a science madman.

Then, Gu Xinyu was surprised to find that there was an old man in a Taoist robe here.

Since she came to this world, it was the first time she had seen the Taoist.

At first, I was a little confused, but then I understood.

Gunpowder was originally invented by ancient alchemists.

From the Warring States period to the early Han Dynasty, the emperors and nobles were intoxicated with the fantasy of immortality, and drove some monks and Taoists to refine the "elixir", and gradually invented the formula of gunpowder in the refining process.

According to historical records, in the process of refining pills for a long time, the ancient alchemists in China discovered that the mixture of nitrate, sulfur and charcoal could burn and explode, thus giving birth to gunpowder, one of the four great inventions of ancient China.

It seems that Grandpa Guo has really found the right person.

Gu Xinyu didn't know much about this, but she provided how to make firebombs, and then these craftsmen used their existing knowledge to perfect it.

The valley here was completely controlled by the imperial court and the military.

Within a radius of hundreds of miles, idle people are not allowed to enter and exit.

After all, there are many people who are risking their lives to find out.

This unique monopoly is temporary, and one day it will be known by others, and at that time, what will it be, Gu Xinyu dare not imagine.

She wants to be a happy little sheep, but unfortunately no matter what meadow, there will always be wild beasts.

"Come, come, I'll show you something." Grandpa Guo was very happy when he saw Gu Xinyu coming, and led her towards a wooden house.

The old Taoist priest's eyes were very cloudy, and he couldn't help but be shocked when he saw Grandpa Guo leading a woman over.

Because he had just been invited here by Grandpa Guo, he hadn't seen Gu Xinyu yet.

How could a woman be allowed here?

Who is she?

When Gu Xinyu approached, his cloudy eyes suddenly released a fine light.

He looked at Gu Xinyu without blinking.

Gu Xin's words don't know why, but in short, it has something to do with his origin or face.

A cultivator who is ten thousand miles taller than him, she can sit and chat together.

Not to mention an ordinary Taoist chief.

So, as she passed by the old Taoist, she smiled and said hello.

Then he followed Grandpa Guo into the wooden house.

In front of the wooden house, there are heavy handles, and it is obvious that the contents of this house are very important.

The house is makeshift but very large.

Gu Xinyu saw a behemoth at a glance.

The black one is placed in the middle.

It seems to be cast in bronze.

"This is the artillery you talked about last time, but the cannon body has just been formed, and there are still a lot of things missing, alas, if it is done, Mu Han will be foolproof in this battle."

Gu Xinyu stayed in place, his mind a little confused.

That's it, artillery is about to come out?

She once told Grandpa Guo that the original artillery did not need to be thrown into a car, nor was it ignited with a fire breaker.

Instead, a kind of iron hollow body is used to fill the fire bomb with gunpowder and other agents, and a fuse to place the medicine wire in a bamboo tube.

When firing, the fire shell is loaded into the barrel, the fuse is lit first, and then the fuse ignites the fire in the barrel, and the fire shell inside will fly to the designated target, and then land and explode.

It is a weapon that is dozens of times more powerful than the current fire bomb.

At the time, she was just talking, because she had only seen it on TV, and she would only talk about the basic function, and she didn't know anything else.

It's like drawing a pie in the air.

And then these people are really going to make this kind of stuff that they haven't seen before.

Gu Xinyu patted the cold cannon body and praised sincerely: "Grandfather, you are really amazing, I don't even know what words to use to describe it." ”

Grandpa Guo laughed, slapped his palm on the cannon body, and said loudly: "I didn't expect this cannon body to really be cast, this is not my credit alone, the hundred craftsmen sent by your eldest brother have played a major role."

"Oh."

Gu Xinyu nodded, of course she didn't know these things, but when she thought about the position of the eldest brother, she understood.

"When will it be done?"

"It's hard to say, those craftsmen are pondering, it is estimated that it will not take half a year."

"Is it hard?"

"Yes, eldest granddaughter-in-law, do you have any other ideas, you can go and guide those craftsmen."

Grandpa Guo sighed a little, this kid just said an idea, and then he can really make such a thing, it seems that as long as he thinks of it, he can do it.

Gu Xinyu hurriedly waved his hand: "That's all I can think of, there is not a word left." ”

She can't come up with any ideas now, it's not that she's modest and cautious, she really doesn't know.

Grandpa Guo shook his head with some regret, his main goal now is to successfully research this artillery.

Now the imperial court is strongly supportive, asking for silver for silver, and for craftsmen to craftsmen, to meet all the requirements he makes.

And among these craftsmen, there are really capable people, and they have actually improved the fire bomb again.

Firebombs are now more powerful and have a twofold increase in explosion range.

The fire bomb that Zhou Muhan brought this time was newly researched.

Gu Xinyu once again looked at the prototype of the artillery, believing that in the near future, she would witness the advent of the artillery with her own eyes.
