"Guzi, you said you were going to destroy the portal from the dungeon to the Lost Lands?, can this work?" Catherine said worriedly, "I also want to go back to Erathia as soon as possible, my mother, and my people are suffering now." Pen %Fun %Pavilion www.biquge.info"

"Catherine, let me try, or I won't leave here with confidence. ”

Catherine saw a rare seriousness in the young man's face. She sighed, "Okay, then you can try it, I'll explain it to them." ”

Easier said than done. Although Gu Shiyu has a plan, he must sort out his own ideas.

Glycerin is produced in large quantities in his daily necessities company, and he also needs concentrated sulfuric acid and concentrated nitric acid. Fortunately, many alchemists will do these things, and there are even ready-made ones that can be purchased.

Slowly pour the strong acid into the glycerin and stir it carefully, and the glycerin will precipitate nitroglycerin, which is a powerful explosive.

However, this production process is quite dangerous, and even a slight vibration or collision may cause a violent explosion.

Nitroglycerin is then immersed in diatomaceous earth to obtain a relatively stable solid explosive.

Diatomaceous earth can also be found in the Lost Lands. The people of Baulston Town use this item with strong adsorption capacity to absorb impurities from domestic sewage in the sewer, and then flow the wastewater into the rivers and seas.

Everything does not need to be produced separately, and what is now done is two steps: one is to mix strong acid with glycerin to obtain nitroglycerin, and the other is to adsorb nitroglycerin with diatomaceous earth.

Oh my God, isn't this a copycat of the famous scientist Nobel's invention patent?

Although the idea came out, Gu Shiyu was still very nervous. If the whole production process is not careful, there may be an explosion, and Nobel's brother was blown to death, and his father was also half killed.

He needed an assistant, and a clever and cautious assistant.

Who is up to the task?

Human and dwarven heroes are accustomed to holding weapons in both hands, dancing with knives and guns every day, and fighting is almost the same, and it is not possible to do such meticulous work. If Yoland's clumsy hands were to hold the embroidery needle and embroider, he would definitely not be able to do it for a minute, and maybe it would add to the chaos.

What about Catherine and Eldrid? Catherine doesn't seem to be able to do it, and a girl who can't even tidy up her own room can be patient and meticulous like that.

Eldrid's room was very tidy at all times, and she should be able to.

What about Ressa? Hey, this little girl hasn't seen her for a few days, and now she used to be with her every day, but now she accompanies Catherine every day, and she is inadvertently alienated from her, she won't have any ideas, right? She's a half-alchemist, and she may be a very good helper.

The rest of the candidates are the witches. These girls who are in the company of herbs every day often deal with bottles and cans, and they are the most suitable candidates.

Gu Shiyu made up his mind, maybe Shengguang Island would award himself an award for this world-changing invention, just like the Nobel Prize back then.

Gu Shiyu immediately summoned his closest friends together. Yolande was tasked with finding a well-ventilated place in the most remote part of the dock to build a new factory, Cuthbert was responsible for purchasing strong acid and diatomaceous earth, and also went to negotiate with the owner of the glassware factory to produce other glassware such as test tubes and beakers; Eledred was clever and good at female workers, so let her make some protective clothing first, fortunately, there were still a dozen dragon scale cloaks in the warehouse that were not rewarded, and it would not be a problem to make a few protective clothing.

"What about us?" asked Resa and McLind.

Gu Shiyu looked at the four witches, Ruisa, Mellind, Angel, Waitis and Tiva, and stopped talking.

"Just say, what do you want us to do?"

"What I want you to do is what alchemists often do, but it is more dangerous than what they do, and requires a hundred times more care and caution. Of course, I'll do it with you as well. Given the high risk of doing this, I will not force you, you are free to choose. ”

"Guzi, we will choose to be with you, if we talk about dealing with glassware, except for alchemists, I am afraid that no one is more familiar with us witches. ”

"Renesas, what about you?"

"Do I need to say that?" Renesa sighed. Don't you know my heart? Whatever you want me to do, I will not hesitate.

"Then so be it!" Gu Shiyu finally made a summary report: "Yoland, Cuthbert, and Edrid, the three of you should be busy first, Melinde, you follow me to the dock, I have to give you explanation and training first." ”

The owner of the glassware factory followed Cuthbert to the docks. The glassware factory was on the verge of closure before, but thanks to Gu Shiyu's daily necessities factory that saved it, he now makes it as fast as he can do whatever he asks him to do.

To do this, a complete set of chemical utensils is indispensable, such as beakers, flasks, test tubes, condenser tubes, funnels, long-neck funnels, separating funnels, alcohol lamps, pipettes, burettes, glass rods, glass catheters, surface dishes, Erlenmeyer flasks, gas collection bottles, fine-mouth bottles, jars, dropper bottles, U-shaped tubes, glass sheets, etc. Maybe there is much more to need, but Gu Shiyu remembers what he saw in the chemistry laboratory, and that's all he can remember.

Gu Shiyu was sketching on the sand, while the boss was shorthand in his notebook, and it took half a day to finish.

"If you don't have any other instructions, then I'll go to production right away!"

Gu Shiyu nodded and said, "Okay, but I hope you can hurry up, not the day after tomorrow at the latest." ”

Yolande and a large group of dwarves were already busy. Gu Shiyu took out a few pots from the factory, broke a few wooden sticks, and asked Ressa and the witches to carefully dump the seawater along the wooden sticks.

"We're just simulating, when you're pouring, you're holding a glass rod in your hand, you have to tilt it at that angle, and then slowly pour in strong acid. ”

"There's a lot of heat generated in the process, so you can't pour it in too quickly, or you're dangerous. ”

"We've done this. McLind laughed, "And we'll use water magic to cool down in the process." ”

"Yes, your proposal is so good, how did I forget that water magic can make ice and cool down! Gu Shiyu patted his thigh happily.

Catherine looked curiously at the boy who had new ideas in his head from time to time. She couldn't understand how her own grain could be so smart.

In fact, none of these things were thought up by Gu Shiyu at all, he just inherited the knowledge of his predecessors. Fortunately, he is just a sports student, and he can't remember too much in his head, nothing more than the poor knowledge of physics and chemistry in high school. If he were a physics or chemistry student, he would definitely change the whole world here.

"Catherine, when we begin, please send heavy guards from this position, and not let anyone approach the hut. ”

"What about me?"

"You can't either!"

Catherine's mouth immediately pursed Lao Gao: "What's the matter, you still have to keep it a secret from me?"

"No, I don't allow others to approach, especially you, because I'm afraid that if something happens, how can I keep it a secret from you?" Gu Shiyu grabbed Catherine's small waist.

"You're weird and scary. You...... You have to be careful with them. ”

"I will!"

When Murak got the news, he immediately went to the town of Baulston, next door to the princess city.

"Lord, have you heard? The people of the Princess City are ready to evacuate!"

"Really?" Gru had finally heard what he wanted to hear the most, he had been waiting for this moment for too long, "what have you heard?"

"Ere's of Yolander and Diya of Roland have both been attacked, and they are clamoring for Gu Shiyu to draw his sword. Altyn had come to the City of Princesses to marry the witch Merlind, and he would definitely ask Guzi to open the seal of the portal as soon as possible. ”

"What does Guzi say?"

"He said that before leaving, he would do one last thing for the Lost Lands, destroying the portal from the dungeon to the Lost Lands and saving the Lost Lands from war. ”

Gru was a little moved, but he immediately shook his head and said, "I'm afraid this thing won't be so easy to do." Only the power of the gods can destroy the portal. ”

"Who knows, Gu Zi always has some strange ideas, and no one can figure him out. ”

"Let's hope he succeeds! We'll have to speed up our preparations. How's the construction of the castles in Shenmu Forest and Hook Bay going?"

"It's coming to an end. Lord, I should go to the Guardian Spirit Forest, where I am needed most right now!"

"But I need you here, too, and the Banshee of the Night isn't yet on the agenda. If they're ready to go back, we'll have to do it ourselves. You wait, and when they leave, you can go to the Guardian Forest. ”

Catherine was also holding a royal council in her palace.

"Sylvia, how many ships have you built for ocean voyages?"

"Your Highness Princess, there are now ten ocean-going warships that have been launched on the docks, each of which can carry a hundred soldiers in addition to sailors and supplies, and we can send a thousand soldiers to Erathia at once. ”

"Let's divide our troops into two routes, one way back from the portal, and you will lead the naval forces through the sea to occupy the Kariad, the mouth of the sea in Erathia. I've heard Gru say that the voyage from the Lost Lands to Erathia is about two months, and you can prepare for the ocean voyage now, and hopefully you will be ready in three days. ”

"Whose troops are you going to set off with me?"

Catherine's eyes swept over the faces of the many heroes in the hall before resting on Christine's face.

"Your Royal Highness, will you let me go, will you? My two hundred or so horses will have to occupy a few boats, and they will need plenty of drinking water and pasture. ”

Unexpectedly, Catherine really nodded. I only heard her say: "Yes, to land on the beach, we need stronger troops." Of all my troops, yours is the strongest and most capable of fighting, and only you can accomplish this difficult task. ”

"What about my horse?"

"Your horse stays, so many heroes are waiting for your horse. ”

"Absolutely not, then my cavalry has become infantry?" said poor old Christine, who almost cried.

"At sea, your soldiers don't need horses. I believe that your warriors, even if they don't have horses, are out-and-out cavalrymen, and their combat power will never be compromised in any way. There are a lot of good horses in Erathia, and I'm sure you'll find what you're looking for when you land. I will give you 100,000 gold coins, and you can go to Erathia to buy them, and you must not rob the horses of the common people. ”

Christine immediately nodded and said, "Well, without a war horse, my warriors will charge into battle like horses!"

"You'll also need a ranged unit to provide cover. ”

Who are you looking for, Eldred is accompanying Gu Shiyu to make powerful explosives! Otherwise, it would be a good choice for her to lead a powerful druid force.

"Your Highness Princess, I will choose eight hundred of the most elite marksmen to reinforce him!" Will Skye, the commander of Catherine's archers, raised his hand.

"Wellskai, of course it's better that you could go, but in that case, you'll have to be separated from Adric!"

Catherine was newly married, and she didn't want to leave Gu is rain for a moment, how could she want to separate her husband and wife.

"Don't mention him, he likes griffons more than he likes me! Let him go with his precious griffins, I am disgusted when I smell the stench of guano all over his body, but he doesn't like to bathe. ”

Everyone couldn't help but laugh. Old Adric, blushing, pulled Christine aside and forced him to swear that he would never fight Wellske's idea.
