Among the materials Chen Xin exchanged from Uncle Ding through Mo Qingyan, in addition to the materials used to upgrade the greenhouse, there are also materials used to upgrade the weapon cabinet.

Chen Xin, who has spent all of his survival on upgrading the greenhouse, has to wait for the new survival to arrive before he can upgrade the weapon cabinet.

"Simple iron weapon cabinet"

"upgrade scheme 1: upgrade cabinet material, enhance cabinet volume, add weapon maintenance and transformation function, existing weapon technology level + 1, upgrade survival 500"

"upgrade scheme 2: upgrade cabinet material, enhance cabinet volume, add gun manufacturing module, obtain gun manufacturing drawing + 1, upgrade survival 450" ”

"do you provide steel, file, claw hammer, vise, hand drill and other materials for upgrading?"

"Scheme 1 materials have been provided, the survival points required for upgrading are reduced by 90%, and the survival points required are 50 points"

"scheme 2 materials have been provided, the survival points required for upgrading are reduced by 90%, and the survival points required are 35 points"

"scheme 1 and scheme 2 upgrade materials are met at the same time, the survival points required for upgrading are reduced by 25 points, and the survival points required are 60 points. Do you want to upgrade?"

After upgrading the planting greenhouse, Chen Xin has gained 13 survival points every day, so after saving for a week, he can upgrade the weapon cabinet.

Naturally, Chen Xin chose to upgrade directly.

The upgraded Guanghua flashed by again. The weapon cabinet, which was originally just a green tin cabinet, became a bigger and stronger dark green cabinet after Guanghua disappeared. At the same time, there was a workbench with tools beside it. There was a weapon rack on the workbench, but now it was empty.

Chen Xin can't wait to open the weapon cabinet. The weapons originally placed in the cabinet have changed qualitatively at this time. It's obvious that the "existing weapons technology level + 1" in the upgrade plan has already taken effect on these weapons.

The change of the two daggers is not obvious. Chen Xin doesn't pay attention to them. The first thing he takes out of the weapon cabinet is the American hunting bow that Mo Qingyan gave him before.

The American hunting bow is considered to be a bow type originated from the Indians. The most important feature of the bow type is that it has an arrow platform. It usually has two bow types: straight bow and reverse bow. Chen Xin's one-piece reverse bow, which was originally made of pure wood, was also a gift from Mo Qingyan when he joined Mo Qingyan's outdoor shop.

But now the wooden bow has changed a lot. Instead of the original wood, the bow body has become black carbon fiber. The handle has also become metal and engineering plastic. There is also a laser sight and ruler on the original platform.

Only the bow type of this bow is still the previous reverse bow, and it has not become a composite bow with higher technology level.

Although he preferred the handle of the original wooden bow, Chen Xin still tried to pull the bow string and wanted to try the handle and strength of the bow.

With this pull, Chen Xin found that when he opened the bow, it was much easier than before, but when he let go, the sound of the bow string rebounding was still loud.

Although no test has been done, Chen Xin can be sure that the tension of the bow has not decreased. On the contrary, it seems to have been improved.

Chen Xin didn't understand the principle, but he thought it had something to do with the material and structure of the bow arm.

After putting the bow back in the weapon cabinet, Chen Xin checked his own quiver. However, it seems that this one is not included in the category of weapons, so it has not been upgraded.

However, the arrows in the quiver have changed from Chen Xin's glass fiber arrows to carbon fiber ones. Even the arrows have been upgraded, from a conical blunt head to a triangular pointed head. You can feel the edge of the arrow when you reach out.

Chen Xin can't help touching his nose. This thing has become a little dangerous.

However, the original technology level of arrow is not high. Even if it is upgraded, there is no high-tech explosion arrow or other more dangerous things, which makes Chen Xin feel some regret.

Perhaps in the original world, these are all controlled dangerous weapons, but in the doomsday world, everyone hopes that the more powerful the weapons used to ensure their own safety, the better.

Besides the bow, the samurai sword in Chen Xin's weapon cabinet also changed a lot.

Originally, the wood handle wrapped with cloth became the material of engineering plastics. The handle with anti-skid texture is very comfortable to hold. The sheath upgraded from wood to metal is also a matte and frosted surface. When the color becomes black, there is almost no reflection.

"Not bad!" Although there is no knife drawn, just the feeling of holding and the weight of the scabbard in the hand give people the feeling that it is a good knife.

Chen Xin doesn't know much about bows. Playing with bows and arrows is just a matter of being pulled to her club by Mo Qingyan to shoot a few arrows occasionally. But he is an obsessive fan of knives.

This samurai sword was originally a real ancient craft which he bought from Yingzhou in the name of handicraft through many relationships.

In order to buy this knife back, when he entered the state of Yan from Yingzhou at that time, he chose not to cut the blade. After Chen Xin received the knife smoothly, he asked professionals to cut the blade a little bit.The so-called "Bei Qian Dao" refers to the "Bei Qian Dao" of the five major Dao systems in Yingzhou, of which Chang Chuan is a branch.

Among the five major sword systems in Yingzhou, Beiqian sword belongs to the best one in quality and quantity. The branch of Beiqian long boat has a long history, and there have been many famous swords in the history, such as Sasaki Kojiro's Beiqian long boat Changguang and Yingzhou Warring States period's famous sword Beiqian long boat cum Guang.

Although this Dao is not so famous for novice Chen, it is also a good one.

The scabbard and handle can only be regarded as external decoration. They can be replaced at any time. It's the blade itself that really decides whether a knife is good or bad.

After taking a deep breath, Chen Xin directly pulled out the love Dao named Sakura cut by himself, and wanted to see what changes have taken place after upgrading this beloved Dao.

With Chen Xin's action, a dark blade, like ink, slid out of the scabbard, and there was no reflection like the scabbard.

This makes Chen Xin a little surprised. It's the first time for him to see this kind of completely non reflective blade. Even this kind of pure black blade in the game is rare.

Chen Xin carefully observed the blade and gently touched it with his fingers. He clearly felt the sharpness of the blade, as if it had been ground very carefully.

But even so, the blade is still pitch black, as if the material itself is pitch black.

What's strange is that the blade doesn't feel as matte and frosted as a scabbard, but as smooth as a mirror, which surprised Chen Xin.
