The sudden change made Lin Tian unexpected, but he understood what Tang Banqing meant. The old man wanted to teach sword-making.

No one in the world of secular or ancient martial arts wants to learn such things as iron. If you want to learn well, you need to spend a lot of time, which is very delaying. Even if he finally became the master of "strike the iron", it is not good for himself, and the forged sword is also busy for others.

Think about it, the people who choose to practice the sword-casting technique are really interested in the sword-casting. It is worthy of admiration. Lin Tian respects Tang Banqing with a sincerity, and then gives a serious gift.

"Well, this time, the sword may be the work of my wife to seal the mountain. I don't know if I will have a chance to find such high-quality materials." Tang Banqing said slightly with emotion.

Her emotions are not unreasonable. Both the heart of the meteorite and the deformed stone are rare treasures. Lin Tian couldn't say that she could find such matching and such materials.

"Lao Tang, when shall we start?" Lin Tian asked.

"Not in a hurry, I'll check the days and weather." Tang Banqing was not in a hurry, turned and walked to the bookshelf.

But Lin Tian was so aggressive, not a girl getting married, it still depends on the days? While still wondering, Tang Banqing came out again, but with an old book in his hand, the cover of the book looked a little yellow.

Tang Banqing went to the yard with the old book. Lin Tian didn't know what she was going to do, so she had to follow along. The strange behavior of the two caused the ideas of other ancient warriors, and many ancient warriors came to watch.

"Brother Lin, what is this old lady doing?" An ancient warrior came to Lin Tian and asked curiously.

Lin Tian also looked at Tang Banqing. Tang Banqing held the old book in one hand, and flicked his fingers with one hand, then looked up at the sky, flipped the pages of the book, and then pointed again, saying something in his mouth, like a warrior in the rivers and lakes, figuring something out.

"Don't Mr. Tang be calculating the weather?" Lin Tian couldn't help but think of the last time Wang Wanxi chose the weather for meditation.

Tang Banqing didn't raise his head, just said aloud, "Let's see, has there been a thunderstorm recently?"

Lin Tian smiled, took out his mobile phone, opened it and looked at it a few times, then said: "Lao Tang, three days later, there will be thunder showers in Tangcheng."

"After three days?" Tang Banqing wondered, turned a few pages of the book, pointed out a few calculations, and then was surprised: "It is really three days later, who did you learn about inference, why did it count so fast?"

The ancient martial artists around laughed for a while because they all saw that Lin Tian was not using any astronomical calculations at all, but looked at the weather forecast on his mobile phone!

"Ahem, Mr. Tang, I was watching the weather forecast on my mobile phone." Lin Tian replied with some embarrassment, fearing to hurt the old lady's face.

"I know the weather forecast. When is the domestic weather forecast so accurate? Many people watch the weather to dry the rice, and the millet is getting wet." Tang Banqing was surprised, his face was disbelieving, which made Lin Tian cry and laugh. .

"Lao Tang, you are talking about the situation a few years ago. Now using weather satellites, the weather forecast is accurate." Lin Tian had no choice but to explain, how long has the wife not been exposed to the current high-tech.

Think of her small building with no TV, no phone, not to mention a mobile phone, a tablet, and so on. Lin Tian had seen it before. The most advanced electrical appliances turned out to be lighting lamps.

Lin Tian thought that Tang Banqing would sigh about the advancement of technology. Who knew that she was glaring: "You are young, and you still have to rely on your phone to watch the weather. If you retreat for a year or even years, you will cut off all electronic products and even cut off all connections. What do you use to look at the weather? Do you look at the sky? "

This remark was so straightforward that Lin Tian was speechless. Those ancient warriors who had just joked the old lady just now were ashamed, because Tang Banqing was telling the truth.

The ancient martial arts here were more or less closed. When they were closed, except for a small amount of food and water sent from the outside world, it really cut off all connections. Even the ancient martial arts reached a barren state, only drank water, and even food. No need.

Tang Banqing didn't even look at the fighters. He turned around and walked back to Dumen Xiaolou. Lin Tian had to follow in. As soon as he entered the door, Tang Banqing threw something over and Lin Tian quickly caught it.

After catching it, it turned out to be the old book just now. Although the paper of the book was a little yellowish, it was tough and smooth in the hands, as delicate as silk.

"It was actually good rice paper." Lin Tian was surprised.

"Boy, you have some eyesight. I dare say that there are 99 people out of 100 who don't understand rice paper." Tang Banqing looked at Lin Tian and was quite appreciative.

Lin Tian was secretly ashamed. In fact, she only knew a few things, or did she only know about the ancient books in the Xiao family. What is the real rice paper? The precious ancient books are rice paper. Rice paper is more durable than the brocade.

The rice paper that is generally bought on the market today is basically fake. The real rice paper manufacturing process is guójiājīmì. Enterprises that manufacture rice paper must have multiple layers of identity verification when they enter.

Real rice paper is flexible, smooth and delicate ~ lightnovelpub.net ~ is not damaged, does not rot, and has a long life of up to 1,000 years. Good rice paper is more durable. Diplomatic documents, advanced files and precious books are used. All are good rice paper.

"Lin Tian, ​​if you want to learn sword casting, learn this book well. This shūjì contains astronomical calculations. This is not a book of fortune telling. It is a book of estimating the time of the day. xiūliàn is also helpful, of course, if you don't like it, you can also return it to me, after all, no young people still like this ancient knowledge. "

Tang Banqing looked up at Lin Tian and said lightly, but in his eyes, there seemed to be some expectation.

"Tang Lao, there are no more books." Lin Tian said very directly that he never refused to come to these precious ancient books. When he was at the Xiao family, he had read all the ancient books in the small building. .

The old man who was a little serious suddenly laughed, but from Lin Tian's point of view, the smile seemed to be a joke, and he couldn't understand why the old lady laughed so much.

Tang Banqing turned around and walked to the desk. Then he found a book under the desk and threw it to Lin Tian. Lin Tian took a look. On the cover of the book, there were four big characters: the outline of the refiner!

"General outline of the refining device?" Lin Tian exaggerated and was surprised: "Is this the secret of sword-making?"

"Hey, you think too much." Tang Banqing smiled mysteriously, and then walked to the bookshelf, she patted the bricks on the wall, and a click suddenly sounded.

Then the bookshelf moved, and when the bookshelf moved away, Lin Tian opened his mouth suddenly when he saw the things behind him.
