Garriman took the pocket watch from the wooden box in the fat goblin's hand with great interest, the soft glow of the only magic lamp in the carriage cast on the surface of the brass alloy pocket watch, reflecting a golden light, and the thumb of his right hand stroked the front shell, and the carved white stag looked brilliant in the light and shade.

Garriman opened the spell book, took out the [Identification Technique] and fired at the pocket watch.

——————————

[Identify M: A first-level prophecy spell.] Spend five mana points to determine the characteristics of a magic item. 】

[Item Name: White Deer Pocket Watch]

[Item Description: This is an elaborate luxury, although it can accurately indicate the time, but it has no other functions.] Oh, and maybe you can use it to show off your wealth. 】

[Item Energy Level: Low]

——————————

Garriman thought that the world would often have long or short black sun phenomena in the future, and he immediately had the desire to buy.

As a businessman, the fat goblin's skill in observing words and emotions must be very high, and he could see at a glance that this mage master's intentions were moving, and he immediately increased his sales efforts.

"How much do you sell this pocket watch?" Garriman clicked the mechanism to open the lid of the case, and the twelve diamonds on the dial reflected psychedelic brilliance in the light, and most of the value of this pocket watch was on these twelve diamonds, brass alloy

"For you, Master Mage, of course, it's just a small amount of money," the fat goblin's smile immediately evolved from respectful to flattering, seeing that Garriman was so happy to ask the price, the fat goblin decided to raise the original price of 15 gold coins in return, "This handmade pocket watch produced by the famous Chamber of Commerce Star Chamber of Commerce only costs eighteen gold coins. ”

Garriman laughed twice, and didn't bargain with the profiteer, he just hung the pocket watch on the vest he was wearing, "I didn't carry so many gold coins when I went out, but I can exchange it with you for something else." ”

"Uh, what do you want to get in exchange? Could it be the magic item called the Light Bomb you just took out? ”

"No, [Light Blast] I'm still useful. How about I can exchange a systematic course of knowledge with you? Garriman said with a seductive smile.

The fat goblin looked dizzy and was hit on the head by a big pie, but it was an old fritter who had been running a business all year round, and several questions came to mind in an instant, "Are you really willing to exchange a system of knowledge for a pocket watch?" It can't be the kind of knowledge that teaches people how to sneeze louder, right? ”

"No, no, no, of course it won't be this kind of knowledge, but really valuable knowledge. I'll just put it bluntly, this knowledge is to teach people how to systematically educate their subordinates to learn mathematical calculations, and I think as a chamber of commerce, this kind of knowledge is of great effect on your development. Garriman said with a smile that in this medieval era, the efficiency of information transmission is still very slow, the process of making paper is still only circulating in the magical world, and the magic network is still mastered by the goddess of magic, and it is only used to provide her followers with memory spell bits, so knowledge is still very expensive at this time.

But for Garriman, who has experienced the information explosion and has been bombarded by alien black technology, the knowledge he has is extremely huge, and when he connects to his soul thinking organ, he can get more knowledge.

The fat goblin swallowed hard, reached out and pulled some collars to change his breath, "This ....... A pocket watch alone can't be exchanged for such a knowledge, right? ”

"You can add other goods to exchange together, anyway, there is no rush now, and it is not too late to continue to discuss in detail after arriving in the main city of the Green Gray Lord." As he said this, the pocket watch had already fallen into his pocket, and he was not going to return it.

Garriman asked the fat goblin for some cloth cut into 32 carat size, as a medium for writing, and began to recall the knowledge of elementary school mathematics in his previous life, combined with the influence of Liu Dada's science fiction novels, the experience of being a rural primary school teacher for several years, and the basic education developed when spreading red ideas in the game, he took out the pen and ink to write down the primary school mathematics textbook with [Mage's Hand].

——————————

[Mage Hand: A zero-level plastic energy spell that costs three mana points to form an invisible magic hand, which can lift items weighing no more than 5 kilograms, and each mana can last for two hours. 】

——————————

Yes, what Garriman is going to use as an exchange for a pocket watch is the elementary school math textbook of the previous life, of course, some of which he has forgotten, but he still remembers these basic knowledge, and the most important exercises, practice questions, application questions, these tricks that can help students quickly grasp the knowledge He still remembers very, very, very, very much, in his previous life, he had been educated by his parents for a long time before the age of eighteen, and there were a lot of questions in his mind.

And then he will also begin to develop education on a large scale, which will be used to raise the knowledge level of ordinary people, and when the knowledge level is not in keeping with the status quo, a large number of high-tech talents will form a new class, and he can cultivate a new interest group with him as the core in the name of the father of education popularization. These methods are all used by him in the game, and he has succeeded and failed, which can be described as full of experience.

Let's set a small goal and make nine-year compulsory education universal.

Let's make the sea of exercises more intense!

Therefore, this knowledge is going to be spread out anyway, and then their added value will plummet like a plunge in housing prices when black technology comes, and now because of the difficulty of information transmission, the added value of knowledge can still be sold at a good price when it is high.

The fat goblin saw that Garriman was writing the math on the cloth, and got out of the carriage early to leave him a private space.

Time passed with Galliman closing his eyes and writing with the Mage's Hand closed, and it was far more comfortable to sit in a carriage than to run through the forest on two legs, and if it weren't for the need to concentrate on recalling memories from his past life and manipulating spells, Garriman would have almost fallen asleep.

Until there was a knock on the wall of the carriage, the voice of the goblin merchant came from outside: "Master Mage, what time is it?" Because the pocket watch is with you, I can't be sure of the time now. ”

"It's half past six in the evening." Garriman sensed that the carriage had stopped, and he stopped writing, got up and stepped out of the carriage.

Outside the carriage, the sky and the earth were as black as ink, and the torches raised by the twenty people only illuminated a small place, and the world seemed infinitely far away, and the thick darkness seemed to extinguish this small light in the next moment.

ps: Thank you for the 100 starting coin reward from the book friend [Ye Qingshuang], thank you for your support.

PS2: The Mage's Hand is divided into variations in the DND, and I didn't quite figure out what the Mage's Hand was assigned to this faction, so I put it in the Plastic Energy system, which is a spell used to manipulate energy or create matter from nothingness. The Master of the Plastic Energy Department is called the Master of Plastic Energy.

ps3: The cold is more than half better, but it's still runny.......
