Although the traffic light had shown them some of the history of the Dayu Empire before, Guo Xiaoshi felt that it was not enough, and if he wanted to understand the world and integrate into it, he had to know more.

There are many books and videos about history on the list, and Guo Xiaoshi chose two suitable ones, spending about five merit points.

Then, following the instructions given by the signal light as he left, he began to search the list for anything about field medicine.

When he looked through the detailed list, he found that battlefield medical care was originally a very large category, with a lot of various things, and it could be divided into many different subcategories, including spells, potions, surgeries, machinery, and many other types.

frowned and thought about it, how did Guo Xiaoshi think that the signal light was unreliable, and he didn't explain it when he spoke, which was simply overwhelming.

"Since it's on the battlefield, first aid should be the most important......

After thinking about it for a while, he finally found a book about on-site first aid and exchanged it for two merit points.

After doing this, Guo Xiaoshi seemed to get up and leave, but as soon as his butt left the chair, he suddenly had an idea, and he couldn't help but sit down again and continue to look at it.

The matter of Spider Crystal really made him feel uneasy, if something like that happened again, he was afraid that he would not have such good luck to survive, so he really wanted to cure his ignorance at this time.

After flipping through for a while, he finally found a copy that he thought was suitable, but when he saw the merit points that needed to be exchanged, he was taken aback again, and he actually asked for a hundred merit points, which was even more "expensive" than the sniper rifle he had exchanged before.

How so?

Guo Xiaoshi took a closer look, yes, it was really a hundred merit points. He thought about it for a while, and looked at other similar things, but was stunned to find that none of them were "cheap", and the starting price was fifty merit points. After a while, he looked through pitifully for a while, and Guo Xiaoshi finally understood a little bit that on this list in the logistics department, none of the information things were "cheap".

This made Guo Xiaoshi suddenly realize that even in this advanced civilization, information is equally important, and the so-called "information age" on the earth is actually not accurate, in fact, information has always run through the development of human society, only the difference between developed and underdeveloped, and the more useful the information, the higher the value.

After figuring it out, Guo Xiaoshi calmed down again, and carefully chose a book that was consciously cost-effective, and spent ninety-seven merit points to redeem it.

Not long after returning to the dormitory, the people in the logistics department sent all the things he had exchanged, and Guo Xiaoshi checked them the same, yes, all of them were worth the money. Especially the sniper rifle, which was so much better than his previous one, that he liked it as soon as he got his hands on it, and he didn't want to put it down after playing for a while.

The whole spear is yellow-gray and has an all-metal structure, and even the handle of the gun is made of metal of unknown quality, which is extremely heavy, but it is just right in his hand, full of texture. There is a small detection lens above the crosshair, which can be connected to the single eye lens of the gun, as long as the lens is put on, it can be aimed synchronously with the gun and transmit various environmental data, which is very convenient.

After playing with the gun "familiar", Guo Xiaoshi retracted his mood and began to pick up "Detailed Explanation of Military Sports" again. When he saw this, he really couldn't put it down, and flipped through the entire book that was half a palm thick in one go, and after reading it, he was stunned for a long time, completely forgetting the passage of time, and then lowered his head and turned it up again.

Although he had learned a full set of military physical techniques from the signal light before, and he consciously learned very well, but after reading this "Detailed Explanation of Military Physical Arts", he found that many things in the past were just swallowing dates, and he learned the movements, but he did not really understand the force skills of these movements and the changes between them.

"The person who wrote this book is definitely a genius...... At the beginning, Guo Xiaoshi secretly sighed while reading it, but gradually, his emotion soon became: "The person who can create this whole set of military physical skills is definitely a genius among geniuses." ”

After reading "Detailed Explanation of Military Sports" continuously, Guo Xiaoshi felt that he had gained a lot every time he read it, but seriously, there are many things in it that must be combined with actual combat, otherwise it will be just talk on paper, so he can only memorize the whole book and prepare to think about it slowly in the future.

After reading "Detailed Explanation of Military Physical Arts", Guo Xiaoshi looked at the "encyclopedia" again. Everything in the book is illustrated and everything is presented in great detail.

Guo Xiaoshi slowly turned page by page, writing down the whole book as he turned it, waiting for all the books to be finished, he felt tired and hungry, a little exhausted and powerless.

I didn't want anything, I fell asleep, I didn't know how long I slept, I ate immediately after waking up, and then Guo Xiaoshi picked up the "encyclopedia" again and flipped it over again to deepen his memory.

After "reading" the encyclopedia twice, closing his eyes and meditating for a while, to make sure that he had really memorized all the contents of the book, Guo Xiaoshi breathed a long sigh of relief and put the book down. This book cost him nearly a hundred merit points, and if he didn't write it down, he would be a little sorry for this merit point.

After a full sleep and a little food, Guo Xiaoshi finally went to read the book about battlefield first aid. Compared with the previous "Detailed Explanation of Military Sports" and "Encyclopedia", Guo Xiaoshi's mood at this time was relatively relaxed, and he read this book completely with a casual attitude.

Because it's not so serious, this book looks relatively fast, after reading it from beginning to end, Guo Xiaoshi has seen a variety of medical methods, but to sum up, the more practical first aid methods on the battlefield are all spells, because the battlefield often encounters a lack of medicine, coupled with the urgency of time, if you want to achieve a good medical effect, spell methods are more like "out of nothing" miracle means.

In order to use spell-based medical methods, the caster must have enough soul power to mobilize the Void Source Energy and transform it into different forms of energy, so as to achieve a good healing effect.

"No wonder I learned this ......"

At this moment, Guo Xiaoshi finally understood the meaning of the signal light to let him learn battlefield medicine, and his bloodline awakening improved his soul power, and it was just the best use of it to learn spell-based medical methods.

After thinking about it, Guo Xiaoshi began to follow the method mentioned in the book, trying to use soul power to transform the Void Source Energy.
