Albert Einstein once repented of the advent of nuclear weapons, and he laid the groundwork for the creation of a weapon that would make warfare even more bloody and brutal. Lord Zhou and the princess talked about the principles of gunpowder explosion and simple gun shooting, which will also lead the world of cold weapon warfare to hot weapons. Zhou Shu just put forward a theory for the sick princess to know, and did not go deeper, he didn't understand anything too complicated for a useless liberal arts student. He thinks that as long as the woman in front of him is given a direction, the sick princess will come up with some gunpowder cannons, and the firearms of this world will slowly develop on this basis. Although this world has magic and unique martial arts, in Zhou Shu's opinion, the vast majority of ordinary soldiers are still not opponents of hot weapons. He didn't know if he was right or wrong to do this, this world has a written history of more than 3,000 years, and no hot weapons have been developed for so long, but gunpowder is about to appear, and in a few tens or hundreds of years, it will probably derive hot weapons on its own. I just speed up the process a little bit and let my acquaintances benefit first, which shouldn't be too much of a bad deed, and it won't delay going to heaven after death.

The sick princess was blind, and it was not easy to understand the principle described by the alien in front of her, and she was ready to ask the weapon research and development department to put down the development of new armor materials at hand and do it to see that kind of gunpowder weapon. This news didn't make her very excited, she still felt that the number of martial arts powerhouses was the key to the success or failure of the battle, and the new weapon Zhou Shu said she thought was just something like a bow and crossbow, and it didn't seem to be able to bring much advantage to the army. The main means of killing the enemy in the soldiers is to strengthen the moves, while the attack power of the crossbow is fixed and cannot be enhanced by manpower. On the battlefield, victory or defeat depends on whether the junior non-commissioned officer can command his squad to perform enhanced moves at the right time to maximize strength.

Zhou Shu saw that the sick princess didn't seem to attach much importance to the news she provided, and was a little unhappy, and said indignantly: "Don't you believe what I say?"

The sick princess hurriedly denied it, "I believe in the theory you said, you think too much." ”

Zhou Shu looked at the first princess who was a little flustered by his words, and found that she was just polite. "You can't help it if you don't believe it. "It's because you don't have vision," I will try to help you with some things in the future, after all, I am quite familiar with you and Fuhu. If you have any trouble, ask someone to come to the school to find me. ”

The sick princess was so happy that she was reassured, and even a rare joy.

Look, I didn't see you so happy when I told you about the principle of guns.

Back in the room, the two Alice sisters were chatting with Ulami. Both of them were also going back to school tomorrow, but they would have to go back after dinner, and tomorrow there would be a collection of jewels on display in the Defeated City, including the largest ruby in the world. During the day, the sisters were going to go over there to have a look, to have a lively or something, but now when they met Zhou Shu and Ula Mystery, they warmly beckoned them to come together.

"The exhibition of jewelry, the largest ruby?" Ula Mystery seemed interested.

Alice shook her hands excitedly, "Yes, yes, there are a lot of jewels on display, and the world's first ruby is said to be the size of a palm, and if you don't look at it, you won't have a chance, as if someone wants to buy it with a lot of money." ”

Ula Myri happily helped his master to make the decision, and prepared to go to see it together tomorrow, but before that, he had to accompany the sisters around the city and go shopping. The two sisters took a lot of the school's benefit fee and were ready to have a luxury. Zhou Shuxin said, the money you take is life money, and the school uses you as bait.

Fortunately, no one really wanted to kill the non-commissioned officers, and Zhou Shu was also willing to go with him to take a look. He has never had the experience of accompanying girls shopping, and he used to often hear that girls shopping is the most troublesome, and most of the men who accompany him will complain. He was especially envious of those who had such extravagant troubles, and this time he was finally able to experience it as he wished.

When I get home, I can also say "It's really troublesome to go shopping with girls".

The four of them chatted for a while, and after nightfall the sisters went back to their rooms. Lord Zhou's magic power hadn't been consumed much throughout the day, and before going to bed, he was going to spend five thousand mana to take a look at the dragon treasure on the second page of the Book of Treasures. But before he could look at it, there was a knock on his door.

"It's so late, who is this?" Zhou Shu went to open the door. He thought it would be sisters or a sick princess, but standing at the door were two men he didn't know, about the same age as himself. Zhou Shu habitually looked at the summoning points of the two in his head, both of which were 50,000 points. He was pretty sure he hadn't seen them. "You're looking for the wrong person, right?"

"May I ask ......," the older man said, "Are you Mr. Zhou Shu?" We are the servants of the Gray Witch, and we have a letter to be handed to you at your command. ”

Gray Witch?This combination of the common words of gray and witch made Zhou Shu nervous for a moment, and hurriedly invited them into the room to talk in detail.

The two men introduced themselves as brothers who had been favored by the Grey Witch and were now following her, Twenty-Three and Twenty-Two, both named Ley. "Mr. Zhou Shu, you can call us Big Lye and Little Ley. ”

Zhou Shu smiled politely at the other party, and Ula Mystery poured water for the two.

Little Lai stared at Zhou Shu's face with some rudeness, and finally looked at his fingers. "Mr. Zhou Shu, Lord Gray Witch, she once gave you a ring, I don't know if it is convenient for you to show it to us, so that we can confirm your identity, so that we can hand over the letter to you. ”

Zhou Shuxin said that it is not strange that this gray witch accepted her little brother, but how did she know that she was in the Defeated Soldier City? He took out the Arabian-style power ring and showed it to the two, and after the two of them looked at it, they nodded and handed over a letter.

Master Zhou was happy when he opened the letter, and the letter was actually written in English. Aren't you afraid that I don't know English?

"Mr. Zhou Shu, can you read the text on the letter? If you can't understand it, the Gray Witch has a sentence for me to relay. The adult asked you to keep the ring, saying that it would be useful when you returned home. She also wants you to stay in the Defeated City for the rest of the time, and she will come to you in a few months. That's all."

Of course, Zhou Shu understands English, and he is colliding with his major, but the English level of the Gray Witch is a little unsatisfactory, and misspellings abound. He shook off the letter and asked Ula to come and read it.

'Zhou Shu, it's great that you can understand English. This world without telephones is a real hassle to contact, please forgive me for being inconvenient and can only communicate with you in the form of letters. Please also don't make fun of my level of English. ’

'The positioning magic I secretly cast on you is about to expire, so I am writing this letter now and having it be delivered to you while I can find you. But it seems that you are going to stay in the Frontier Defeated City, and this letter will be in your hands to prove that you are still there. I was really lucky. ’

Master Zhou read the sentence with a smile. This gray witch's writing is really polite, not like her at all. He had thought it strange before, the first night he had arrived in this world, the gray witch had left on her own, and then reappeared in front of him a few hours later. At that time, Zhou Shu had already walked far away from his original location, and there were dense woods nearby, and he couldn't figure out how the gray witch found him, but now he got the answer. It turns out that people have done a GPRS magic on themselves.

'I am honored to share a piece of good news with you. I've found a way back to our hometown, and if it's a good idea, we'll both be able to go back in a year's time. But only if you take care of your ring, we need to borrow its power. And I want you to stay in the Defeated City so that I can find you in time. ’

Reading the letter, Zhou Shu and Ula Mystery had an urge to hug each other and cry. I didn't expect happiness to come so suddenly, and there was no clue at all, but now I even set a date for going back. Zhou Shu looked at the word 'one year later' on the letter, and his heart was full of thoughts. In a year's time, what will my hometown look like? Will anyone still remember me? My mother will cry when she sees her son, who has been missing for a year, suddenly appear? What kind of career will she accomplish when she returns to modern society?

Zhou Shu forced himself not to think about this, and continued to read the letter.

'It's a hassle to make the magic array that the two of us need to go home, and it's hard to find the necessary materials. The brother who delivered the letter for you is also tasked with helping me find one of these materials, and I hope you can help them if possible. These two are inhabitants of this world, and although they have vowed to help me get home, I don't fully trust them. I hope you can judge for yourself how to deal with that brother, and if they do anything offensive to you, I hope you will try to forgive them. ’

"At this time, I am in the southern magic city of the White Moon Country, a place called 'Rozelavin'. I'd love to show you what I've gotten here, but I'm constrained by letters and my poor English. Finally, I will take the time to go to the Defeated City to find you at the end of the year at the earliest, and then I will talk to you in detail. Good luck and love you little witch on. ’

"Love your little witch, up. Ula riddle read these words playfully in English, full of intimidation.

Zhou Shu panicked suddenly, "Oh dear, she is a foreigner, and she is so virtuous when she writes letters." He remembered that the Grey Witch had said that in the fairy tales she read when she was a child, there were often little witches who found the Ring of Breaking Boundaries and came to the other world, and this signature should refer to this.

The date of the letter was ten days ago, and Master Zhou didn't know how far away that magic city Luo Zeravin was from here, but the two of them were able to arrive so quickly and find out themselves, which showed that they still had some skills. Ula Mystery has seen the map of Baiyue Kingdom in history class, and the distance between Luo Zeravin and the defeated army city is very far, probably the distance from Fujian to Liaoning. The two men arrived in ten days, which shows that although their speed is not as fast as that of a train, it is certainly much better than a car, after all, there are no highways in this world.

When the Ley brothers saw that Zhou Shu had finished reading the letter, they saluted him and prepared to leave.

These two people are really too efficient to do things, and they don't say a word.

"Blah, blah, blah!" Zhou Shu stopped the two, "The Gray Witch guy said in the letter that you are going to find some materials, and let me help you ......"

Da Lai Yi interrupted Zhou Shu with a smile and waved his hand, and said proudly: "That's just a small matter, our two brothers can handle it." ”

"But......" Zhou Shu, a good old man, still wanted to say a few polite words. Unexpectedly, little Lai waved his hand and said, "This gentleman, we appreciate your kindness." What the Gray Witch is looking for may be a bit difficult for others, but we are professionals and it is easy to get it. ”

Da Lai Yi also nodded and smiled: "Actually, our family's family motto is that kindness must be repaid, debts must be repaid, and we will never owe favors." So it's still a hassle for us if you come to help. ”

The two brothers have a tacit understanding together, and it may not be a good thing to have one more person who is stronger than them. What's more, this person is just a little non-commissioned officer who has not entered the gate of martial arts.

Master Zhou keenly felt that the other party was disgusted with him, and he didn't like that boring, so he didn't say anything to send the two away.
