Wu Zhi quickly waved his hand, telling him to stop talking nonsense and bring the things quickly.
"You sell me the things first, and I'll tell you the next time I come back!"
Wu Zhi doesn't blame the young apprentice for thinking that way.
After all, those things in ancient times were generally things that experienced people were willing to poke fun at.
There are very few that are truly used on the right path.
These items add up to more than 100 kilograms.
If you include several jars of wine, one hundred, seventeen or eighty kilograms would not be able to hold it back.
Fortunately, Wu Zhi is physically strong and has certain martial arts skills.
So even though it's a bit difficult to pick up these things, it's no problem to persevere.
But when he thought about how many miles he would have to walk after returning to the palace, he gave up the idea of carrying these things back.
I went to the market and bought a wooden trolley.
When Wu Zhi pushed these things and came to the palace gate.
Although the guards all knew Wu Zhi, since he brought quite a lot of things on this trip, they carried out a routine inspection of the things on Wu Zhi's trolley.
As for the purpose of those things, Wu Zhi made nonsense and said that they were bought for Gao Youcai in the cleansing room.
Because Gao Youcai recently had a dream about attaining enlightenment and becoming an immortal, the immortal in the dream asked him to get these things to make an elixir.
So after he woke up, he found Wu Zhi and asked him to help him purchase it.
After the elixir was refined, Wu Zhi promised to share one with him, so Wu Zhi agreed.
The guards who were responsible for guarding the palace gate were stunned for a moment after being fooled by Wu Zhi.
With endless yearning in his heart, he reached a py deal with Wu Zhi.
Each of them was willing to raise two hundred taels to beg for one.
Originally, Wu Zhi had something on his mind and didn't want to delay at the palace gate for too long.
But at this time, seeing the extremely expectant and yearning expressions on the guards' faces, he agreed with a look of embarrassment.
Just like that, the guards happily let Wu Zhi go.
These guards are so ignorant.
Wu Zhi was able to deceive them all with just a few words.
In fact, this is not an extremely absurd thing.
After all, Song Jiang relied on a set of tricks by the Nine-Tian Xuannv Empress to entrust her with a dream, and the trick of a stone tablet dropped from the sky, and deceived more than a hundred heroes on Shuibo Liang Mountain into confusion.
In fact, this has a lot to do with the fact that Zhao Ji, an official of the Song Dynasty, and his group of ministers blindly praised those who cultivated immortality.
When Wu Zhi returned to Gao Youcai's cabin, it was already an hour later.
Gao Youcai, on the other hand, had already prepared the meal and was waiting for Wu Zhi.
When I saw him buying the drinks, a smile appeared on his face.
The meal lasted for more than an hour, and the two of them chatted happily during the meal.
Shortly after the meal, Gao Youcai fell into a deep sleep due to excessive drinking.
And now, it's time for Wu Zhi to stretch his muscles.
He first took some plates and bowls from Gao Youcai's hut.
Then they carefully mixed saltpeter, charcoal, sulfur and other materials into gunpowder in a certain proportion.
Because this ratio is the result obtained by Liu Laosan after hundreds of experiments.
So at this time, Wu Zhi can just take it and use it.
After he completed the gunpowder ratio, the next step was to choose the grenade shell.
Wu Zhi knew that the best material was cast iron.
Because that thing is not only hard in texture, but can also produce dozens of shrapnel under violent explosions.
Driven by the power of the huge explosion, the dozens of shrapnel, like extremely fast darts, will penetrate deeply into the enemy's body and cause huge damage to them.
However, if the cast iron shell is to be made, it would be extremely difficult to realize based on the current construction technology on Shuibo Liangshan. It is simply unimaginable.
At this time, another material is needed instead.
First of all, what appeared in Wu Zhi's mind was naturally the bamboo tube, which was very convenient to use.
Not only does that thing have better airtightness, it is also easy to obtain materials, and it can also be mass-produced in a short time.
However, this kind of bamboo tube is much less resistant to impact when the gunpowder is transformed into high-pressure gas.
The direct result of this is that even if a certain amount of iron filings or sand is stuffed into the bamboo tube and gunpowder to increase the killing power, it will not be able to achieve the best killing effect.
To put it simply, using bamboo tubes to make firecrackers is okay, but if it is used to make lethal weapons, its power is not enough.
What if the cavity of the grenade is made of rock?
Rocks are hard in texture, and when exposed to internal pressure, the external rock cavity will be exploded into rubble.
And those stones flying around can also cause a certain degree of damage to the enemy.
But that thing will also face many problems during the production process.
One of the main problems is that if the stones chosen are smaller, the power will inevitably be lower.
But if the stone you choose is too large, it will be inconvenient to carry.
And when rough processing these stones, a lot of manpower is consumed.
After Wu Zhi thought about it for a long time, he decided to focus on the firecrackers in his previous life.
He wanted to use layers of tough tissue paper as the cavity of the grenade.
And create a partition inside it.
Its head is filled with gravel or metal filings.
Then fill the second half with explosives.
After the fuse is ignited and thrown out, the huge explosive force in the cavity can blow the hard filling inside several meters away.
In this way, effective damage to the enemy can be achieved.
Whether it is the tough papyrus used as the cavity, the gravel and fine iron filings used for the main killing force, or the gunpowder inside, they are all extremely cheap things.
After they arrive in Liangshan and thoroughly understand this technology, they can produce it in large quantities and apply it on the battlefield.
At that time, as long as the enemy soldiers on the battlefield are not wearing heavy armor, if they face hundreds of simple grenades thrown at the same time, even if the opponent will not be wiped out in one wave, they will be blown up and scattered.
.
At the same time, this weapon is extremely portable and can be used at any time as long as it does not encounter heavy rain.
Of course, in this harem, there is definitely no equipment for rolling tough papyrus.
But Wu Zhi could have taken down some bamboo tubes from the bamboo forest, and then made a small partition in the bamboo tubes.
And put gravel on top of the partition.
Under it, fill the proportioned gunpowder to test the feasibility and explosive power of this crude grenade.
