Chapter 60: 60. A must-have recipe

But... the knowledge that can conquer this world.

Nancy felt that even Master Bayerwock of the Gemansis Secret Order would not dare to say such a thing.

But Nancy didn't think Lu Cheng was joking. She tried hard to lift the table in front of her, but her strength was very limited. It took her less than two seconds to lift it before Nancy felt dizzy. She had no choice but to put the table down.

During the time when the Scarre Blood Crystal Beast Plague was raging, her body became very weak.

At noon, Nancy felt out of breath when she followed Lu Cheng for a walk back to the camp.

"Where are you moving the table?"

Elena lifted Nancy's desk easily and asked Nancy questions while holding the desk.

"Just go a little further ahead. Thank you, Your Majesty Elena." Nancy looked at Elena's relaxed look and felt a little envious.

Elena placed the wooden table in the row in front of Nancy, right... in the aisle between the wooden tables.

"Can't you see the blackboard from where you are sitting?" Lu Cheng asked.

"My eyes... are cursed. It may be because I read too much knowledge. I can't see things clearly when I look too far away."

Nancy hesitated for a while and finally told Lu Cheng about this. In her opinion, this was not a fatal weakness.

“Isn’t this myopia?”

Lu Cheng knew that a girl who loved reading might not have very good eyesight. The curse that Nancy mentioned was probably a symptom of myopia. On the other hand, Elena... this girl could see clearly what was on the blackboard even when sitting in the last row of the classroom.

“Recently…” Nancy, like Elena, had a stuttering problem when reading Chinese. Elena is much better now. She can read three Chinese characters in a row without stuttering!

"Forget it, Nancy... Elena, the knowledge I am about to tell you may change the pattern of war in this world. Elena's words don't matter. Miss Nancy, please remember that our kindness is not unconditional." Lu Cheng said to Nancy in a very serious tone.

Nancy, who was called out, clenched the charcoal pencil in her hand. She knew what Lu Cheng was reminding her of.

Just as Lu Cheng said at the beginning, knowledge is not free, although this time Lu Cheng taught her this knowledge that could change the world for "free".

But Nancy didn't think there wouldn't be any follow-up conditions after this knowledge.

This was a friendly signal sent by Lucheng. This signal was not sent to Nancy, but to the Xiuenzhelai Kingdom behind Nancy.

More importantly, Lu Cheng was willing to share this knowledge with her, which also showed that this knowledge was not so rare in their world.

"I know what I'm doing." Nancy also said in a serious tone.

"I hope so. This knowledge is about weapons. You want to get rid of the most basic weapon technology in the era of using swords."

Lu Cheng wrote down the simplest formula in their own words on the blackboard. It was a must-have recipe for time travel, and it was black gunpowder, one of the four great inventions of China.

For Lucheng, which has already started in the information age, the formula of black powder is of no use, but it is a good choice to use it as a bargaining chip.

"Stinky Stone, White Flame Stone, and...Charcoal?"

Nancy read out the three words Lu Cheng wrote on the blackboard one by one.

These words were written by Lu Cheng based on the memory in his mind, using the names of this world... converted into Chinese, they are sulfur, saltpeter, and charcoal.

"I've seen similar alchemical formulas at the Gemansis Secret Society. When they add the wings of colorful butterflies and the tail of a fire lizard, it turns into a flame that can burn colorful light," said Nancy.

"Then you can remove the wings of the colorful butterfly and the tail of the blazing fire lizard, and mix these three raw materials together in a ratio of 2:15:3, and you can make a weapon called gunpowder."

Lu Cheng felt that as long as Nancy understood this passage, she could go back to her country and tell her king, "Let's wait for a wave of technology and then go and defeat them."

Gunpowder was indeed another important invention that changed the battlefield, but if Nancy wanted to truly bring out the power of gunpowder, she still had to overcome a lot of long-term problems in weapon manufacturing.

"Did you know that this alchemical formula could produce... weapons like yours?" Nancy asked this question, but the moment she asked it, she realized that she had said the wrong thing.

The reason she came to this camp was because she was shocked by the scene in the defense of Skare that day when the blood crystal beast that could have completely devoured the entire Skare was destroyed by thousands of fires from the sky.

"Although he is very smart, is he still too young?" Lu Cheng murmured to himself. His voice was not small and Nancy could hear it clearly.

"I have been old enough to get married for almost five years. I am no longer young."

Nancy's abilities were often doubted in the secret society because of her age. She used this way to tell Lu Cheng that she had been an adult for a long time.

However... on Earth, having passed five years by the age of marriage is not something to brag about, but in this world, if Lu Cheng remembers correctly, one can get married at the age of fourteen

"I'm not talking about you, but your world." Lu Cheng was actually referring to Nancy, but it was Nancy's naive idea.

Rabbits invented gunpowder more than a thousand years ago, but it took a long time for the prototype of the weapon such as the gun to appear.

The biggest reason is that the manufacturing technology cannot keep up... With the manufacturing technology of this world, even if they have magic and golems that can be used as cheats, in order to develop to the level of modern weapon manufacturing, I don’t know how much prerequisite technology needs to be lit up.

This is also the reason why Lu Cheng can safely use black powder as a bargaining chip, or a knocking hammer, to Nancy.

Nancy is a smart girl. Smart means that Nancy knows how to communicate with Lu Cheng in order to gain greater benefits, and her forward-looking vision is also the reason why Lu Cheng values her.

"Gunpowder is just the very first step in our weapons. It is also a very scary weapon in itself. As long as a certain amount of it is gathered, it can produce a terrifying explosion. However, with your current abilities, there is indeed a way to use it effectively." Lu Cheng said.

“Is the method of using it also free?”

Nancy has written down everything Lu Cheng wrote on the blackboard. During this time, she has been thinking about how to use this alchemical formula that can produce a terrifying explosion.

"There are not so many free things in the world, but you need to pay for what follows. Just help me convey a signal to your father." Lu Cheng was of course referring to the king of Skare's neighboring country.
