When Gervais and Anna arrived at the hall, not long after, a messenger dressed as a footman was led in by Thomas.

When the messenger dressed as a valet came to Gervais, he saw the huge wolf head on Gervais's desk and chair, and the sharp teeth exposed in the wolf head's mouth. His pupils couldn't help but shrink, and his body trembled slightly, but he still

Fortunately, he now represented his master and did not dare to show anything that would damage Baron Pat's face. He tried his best to suppress the panic he had just experienced for a moment.

"Dear Lord Baron, my master, Baron Pat, asked me to bring you my most sincere greetings!"

After Baron Pat's messenger came to Gervais, he saluted Gervais, and then said to Gervais in a respectful tone.

"Thank you Baron Pat for your greetings. I wonder why Baron Pat sent you to my castle this time?"

Gervais sat in his special seat with his back straight and his right hand stroking the storm wolf head on the armrest. Although Thomas and Anna did not notice the performance of the messenger just now, they could not escape Gervais's eyes. This made Gervais

Some suspect that the current appearance must be very similar to those mountain kings in movies on Earth.

"Dear Lord Baron, this is a letter handwritten by my master, Baron Pat. Please read it!"

The messenger immediately took out a chapter of envelopes from his arms, bent over and held them up to the front.

When Anna next to Gervais saw it, she immediately stepped forward to take the envelope and handed it to Gervais.

Gervais took the envelope and pushed away the wax paint, took out the letter paper and began to read.

"Sir Gervais, I have the temerity to send someone to disturb you, but as your neighbor, I feel it is necessary to visit you to enhance the relationship between you and me. In order not to appear abrupt, I specially sent a servant to deliver the message.

, I will leave tomorrow and arrive at your castle with my friendship and gifts! Pat Bowyer"

Before picking up the letter, Gervais had speculated whether Baron Pat had invited him to some kind of banquet, but after reading the letter, Gervais was a little confused.

If people want to get closer to neighbors, they always invite guests to come. It would be better for Baron Pat to directly say that he wants to be a guest at Gervais's place. How thick-skinned do you have to be to be a guest at a stranger's house for no reason?

ah.

But fortunately, Baron Pat said he would come with a gift, otherwise Baron Gervaispat might have encountered some difficulties and couldn't afford to eat and wanted to come here to eat.

"Has Baron Pat said the reason for his coming tomorrow?"

Gervais put down the letter, looked at the messenger, and asked him.

"My Lord Baron, I am very sorry. My master has no additional instructions. He just asked me to bring you his sincere greetings and this letter."

When the messenger heard Gervais' answer, he withdrew his gaze from the strange storm wolf's head, and then respectfully answered Gervais.

"Well, in that case, please help me tell Baron Pat that I very much welcome his visit and look forward to his arrival tomorrow!"

Since nothing could be found out about the messenger, Gervais no longer thought about it. Anyway, the reason why Baron Pat came to find him will be known tomorrow.

"Yes, Lord Baron, I will bring your words to my master, and the villain will take his leave!"

After the messenger wrote down Gervais's words, he immediately saluted Gervais.

…

After Pat's messenger left, Gervais came to the vestibule and walked to the stone house where the gunpowder was stored. Since the fence was built here, Gervais moved his grenade manufacturing workshop from the mill to this place.

On the other side, there is a fence blocking it to prevent people from sneaking into the stone house. More importantly, this side is far away from the city wall and the castle wall. Even if an accident occurs, the castle will not be greatly damaged by the explosion.

The door of Gervais's stone house was named the laboratory by him. Although the servants didn't understand it, as long as Gervais told him to go to the laboratory, Anna would wait for him obediently in the inner castle and would not follow him here.

, because only Gervais can enter this laboratory.

Since the successful test explosion of the simple grenade, Gervais has been thinking about how to make a new fuse. Because the fuse he made the first time was too simple and burned very fast, he needed to lengthen the fuse to ensure his own safety, but it was two meters long.

It is impossible to use long leads in actual combat. It is completely useless, so Gervais has been experimenting with what materials are more suitable for making leads.

To slow down the burning speed of the fuse, but not too slowly, Gervais first thought of reducing the content of gunpowder, but found that it was useless. Then Gervais started with materials, first replacing paper with linen thread

, but it is not ideal, because linen thread does not absorb water, and gunpowder will easily fall off after it dries, and it will probably go out after being ignited and thrown out. Yesterday, Gervais finally thought of something, that is cotton, because of this

The world's cotton output is not high, and cotton is even more popular among nobles than wool. Only nobles can afford cotton-padded clothes, and Gervais only owns two sets of cotton-padded clothes in total.

After thinking about cotton, Gervais immediately took out his own set of cotton-padded clothes and pulled out a small handful of cotton directly from the small hole in the cotton-padded coat. The holes in this cotton-padded coat were cut by Gervais when he went to the dark forest that day.

Yes, the cotton used to block the nose was officially dug out of this cotton-padded coat.

After getting the cotton, Gervais twisted the cotton into a thin rope, then mixed the gunpowder into the boiled wheat soup, and mixed the two together. The gunpowder became sticky and difficult to fall off, and then tied the cotton rope.

After being soaked in it, the entire cotton rope was soaked with gunpowder after being taken out, so Gervais left it to dry directly.

Gervais dared to come here today just to test whether its cotton lead wire could achieve the expected effect. When Gervais picked up the black, slender lead wire, he cut it off by one with scissors.

After a short period of time, he came to the open space outside the house and used kindling to light the cotton fuse.

Hiss~

1,2,3...7,8!

"Haha! Success!"

After lighting a five- to six-centimeter piece of fuse, Gervais was surprised to find that the burning speed of the cotton fuse was exactly what he expected. It was exactly the same as the burning speed of the fireworks in his previous life. As long as the length of the fuse was controlled, it would be safe.

The use of grenades.

The success of the fuse means that Gervais's grenade will soon be produced and truly reach the point of actual combat. It also means that he will be able to find trouble with the unicorn again tomorrow and the day after tomorrow. If he can really rely on this grenade to kill the unicorn,

If the monster is killed, Gervais will definitely make a lot of money. One thousand eight hundred kilograms of monster meat is worth more than 80 gold coins, and the horn of the unicorn is definitely worth a lot of money. Thinking of this, Gervais's heart is burning.
