In one transaction, both of them left a pretty good impression on each other. After closing the transaction window and ending the conversation with Zhong Mo, Luo Ji earned four million civilization points. Luo Ji, who became rich overnight, was in a good mood.

He hummed a little tune, and he couldn't sleep in a short time anyway. Luo Ji planned to take advantage of the opportunity to visit the auction house, but before that, he had to buy a battle-free sign and hang it up.

The war-free card is a good thing. Once activated, it can prevent your world from being invaded or declared war by other players for a month. Moreover, probably considering that most novices are poor, the price is only set at 10,000 civilization points.

The only mercy left in a malicious system.

However, these 10,000-yuan combat-free cards cannot be bought casually. Only after experiencing a player battle, you will get an opportunity to purchase the combat-free cards. Once purchased, they will take effect immediately, and the purchase opportunities cannot be stacked. In other words

, even if you choose to keep the purchase opportunity after finishing a player battle, and then fight again, the purchase opportunity will not increase to two times, and in the end you will only be able to buy one battle-free card.

After neatly buying a war-free sign and hanging it up, Luo Ji could finally browse the auction house with peace of mind. After seriously thinking about his current shortcomings, Luo Ji immediately thought of the medical development in his tribe, "Yes.

Yes, skill book! Is there any medical skill book?”

His tribe lacked medical talents. Since he couldn't find any, he should just spend his civilization points to buy skill books from the head office? With this idea in mind, Luo Ji decisively entered the words 'medical' and 'skill books' into the auction house.

A keyword, after this search, he actually found it.

But what is regrettable is that these medical skill books are obviously hot commodities. Most of the skill books in the auction house are black iron level and bronze level skill books. There is only one silver level medical skill book.

Disease Research' is still in the bidding mode. The bidding time is 24 hours. The price has now reached 1.37 million, and there are still 16 hours left before the bidding ends.

Luo Ji didn't believe that no one was watching this. As a rare skill book, even if it was silver-level, it could still be sold for the price of a gold-level item. There were definitely many players waiting for the last minute of this auction.

Even if there is a sudden quotation at the last second, it is conceivable how high the price will soar by then.

After taking a deep breath, Luo Ji kept his calm mind and clicked on the silver-level skill book to see the effects...

Disease Research (Silver Level): Faced with known disease symptoms, the speed of researching the disease is increased by 40%, and the chance of developing a treatment method is increased by 30%.

Okay, he needs this, he needs it very much! After seeing the effect of the skill, Luo Ji looked crazy, "Ahhhhh! Why is it an auction!!"

The bidding mode is too unfriendly for newcomers. Think about Zhong Mo before, who could get out four million civilization points in a minute without any hesitation. If a big boss like this joins, he will be richer.

How could it be possible to beat them?

Luo Ji took a long, heavy breath and cheered up. Although his hope was slim, he couldn't give up just like that! He still had more than four million civilization points in his hand, so it wasn't completely out of the question.

Luo Ji was very determined to take pictures of this skill book, and he was even willing to do so at any cost! After all, his civilization was so lacking in this, and the development of medical treatment had not been able to find a breakthrough, and this 'Disease Research' book

The silver-level skill book can obviously create a breakthrough for him!

For this reason, Luo Ji was not in the mood to buy anything else, so taking a picture of this skill book became his first priority! Before that, just in case, he wanted to buy the more than four million yuan in his hand

Keep all the civilization points.

After closing the auction page, Luo Ji, who had nothing to do, lay down on the bed and took a nap. Early the next morning, he went directly to the Ordnance Department with the thick stack of three-bow crossbow design drawings.

At this time, except for the little fox who lives directly in the Ordnance Department's camp, there is no one there for the time being. After getting through the previous busy and stressful period, everyone in the Ordnance Department finally had some peace.

In their free days, there is no shortage of arrows and stone bullets. Their daily work now is basically to make a few sets of spare leather armors and bows and arrows. In addition, they help polish blunt weapons, which are not particularly urgent.

Naturally, there was no need to work early in the morning or stay late at night, so Luo Ji turned a blind eye to this.

The little fox, who was bored at this time, was holding a long bow in his hand and wondering where he could improve it. When he saw Luo Ji coming in, his whole body suddenly changed from his previous indifference, and his eyes that kept shining directly

It landed on the thick stack of blueprints in Luo Ji's hand, "Chief, are you holding the blueprints for the new weapon?"

Regarding the little fox's character, Luo Ji was a little bit dumbfounded, but he was too lazy to tease her, and directly handed over the design drawing in his hand, "Yes, the new weapon, this thing is called the Three-Gong Crossbow, a kind of siege equipment...

…”

While Luo Ji was talking, the little fox had already taken the stack of design drawings and flipped through them page after page. Her keen intuition about military equipment allowed her to read just through the patterns on the drawings.

He clearly felt the power and complexity of this thing. However, as he looked at it, the expression on the little fox's face suddenly became bitter, "Chief, what do the lot of strange symbols next to this pattern mean?

"

After hearing this, Luo Ji glanced at the so-called strange symbol subconsciously, and then couldn't help but put his hand on his forehead, "I almost forgot, the people in the Ordnance Department are not literate yet..."

On the design drawing of this three-bow crossbow, in addition to the patterns, there are a lot of words. If you can't understand the text information, the difficulty of making it will be at least doubled. "That's not a strange symbol, that's a word."

"Word?" The little fox tilted his head, his face full of confusion.

"It just so happens that your Ordnance Department has been relatively free recently. Starting today, all members of the Ordnance Department will have classes with the children in the tribe after noon every day, and they have taught me all the words on this!" Although Luo Ji can also do it!

Choose a simpler method, such as letting him directly tell the little fox the meaning of the text information, but this is troublesome. You can't ask him to interpret the design drawings every time in the future, right? It is urgent to learn text, so let him learn it early.
Chapter completed!
