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

It's just that Chen Xin, who has spent all his survival points on upgrading the greenhouse, must wait for the new survival points to arrive before he can upgrade the weapon cabinet.

"Simple Iron Weapon Cabinet"

"Upgrade plan 1: upgrade the cabinet material, increase the cabinet volume, add weapon maintenance and transformation functions, the existing weapon technology level is +1, and the survival point required for the upgrade is 500"

"Upgrade plan 2: upgrade the cabinet material, increase the cabinet volume, add the gun manufacturing module, get the gun manufacturing blueprint +1, and upgrade the survival point required 450"

"Do you offer materials such as steel, files, claw hammers, vices, hand drills, etc., for upgrades?"

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

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

"Plan 1 and Plan 2 upgrade materials are met at the same time, the survival point required for the upgrade is reduced by 25 points, and the survival point required is 60 points, do you choose to upgrade?"

After upgrading the Cultivation Greenhouse, Chen Xin can already gain 13 survival points per day, so after accumulating for a week, he can already upgrade the weapon cabinet.

Naturally, Chen Xin directly chose to upgrade.

The upgraded brilliance flashed again, and the weapon cabinet, which was originally just a green iron cabinet, became a larger, sturdier dark green cabinet after the brilliance dissipated, and at the same time, there was an extra workbench with tools next to it, and there was a weapon pylons on the workbench, but now it was empty.

Chen Xin couldn't wait to open the weapon cabinet, and the weapons that were originally placed in the cabinet had changed qualitatively at this time, obviously the "existing weapon technology level +1" in the upgrade plan had already taken effect on these weapons.

The change in the two daggers was not very obvious, Chen Xin didn't pay attention, the first thing he took out from the weapon cabinet was the American-style hunting bow that Mo Qingyan had given him before.

The American hunting bow is considered to be a bow type derived from the Indians, the biggest feature is that it has an arrow platform, usually with two bow types: straight pull and recurve, Chen Xin's original pure wooden one-piece recurve bow is also a gift from Mo Qingyan when he joined Mo Qingyan's outdoor store membership.

However, now the wooden recurve bow has changed a lot, the bow body is no longer the original wood, but has become black carbon fiber, the grip has also become made of metal and engineering plastics, and the original arrow platform has an extra laser sight and ruler.

Only this bow is still the same as the previous recurve bow, and has not become a compound bow that seems to have a higher technology level.

Although he preferred the feel of the original wooden bow, Chen Xin still tried to pull the bowstring, wanting to try the feel and strength of the bow.

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

Although it has not been tested, Chen Xin can still be sure that the tension of this bow has not decreased, on the contrary, it seems to have improved.

Chen Xin didn't understand the principle of this, but it was supposed to be related to the material of the bow arm and its structure.

Putting the bow back in the weapon cabinet, Chen Xin checked the quiver he was holding the arrow again, but this didn't seem to be counted in the category of weapons, so it wasn't upgraded.

However, the arrows in the quiver have changed from Chen Xin's original fiberglass arrows to carbon fiber arrows, and even the arrows have been upgraded, from a conical blunt head to a three-edged pointed end, and you can feel the blade of the arrow when you reach out and touch it.

Chen Xin couldn't help but touch his nose, this thing has become a little dangerous.

However, the original technology level of the arrow was not high, even if it was upgraded by one level, there were no more dangerous things such as high-tech explosive arrows, which made Chen Xin feel a little regretful.

In the original world, these were all dangerous weapons that were regulated, but in the apocalyptic world, everyone wants to use as many weapons as possible to keep them safe.

In addition to the bow, the katana in Chen Xin's arsenal has also changed a lot.

The wooden handle that was originally wrapped in strips of cloth has been made of engineering plastic, and the frosted handle with anti-skid texture is extremely comfortable to hold, while the scabbard that has been upgraded from wood to metal has the same matte matte surface, and the color changes to black, so there is almost no reflection.

"Not bad!" Although the knife is not drawn, the feeling of holding it and the weight of the sheath in the hand give the impression that it is a good knife.

Chen Xin doesn't know much about bows, and playing with bows and arrows is just a few arrows that Mo Qingyan pulls to her club, but he is an obsessive lover of knives.

This katana was originally a real ancient hand-made Bizen longship that he bought from Yingzhou in the name of crafts through a lot of connections.

In order to buy this knife back, when he entered the Yan Kingdom from Yingzhou, the blade of the knife chose not to open the blade, or after Chen Xin successfully received the knife, he asked a professional to open the knife little by little.

The so-called Bizen refers to the Bizen knife in the five major knife systems of Yingzhou, and the long ship is one of the branches.

Bizen's knives belong to the best in quality and quantity among the five major knife systems in Yingzhou, and the branch of Bizen Nagafune has a long history, and there have been many famous swords in history, such as Sasaki Kojiro's Bizen Nagabuna Captain Hikatsu, and the famous sword Bizen Nagafune Kanemitsu of the Yingzhou Warring States Period.

Although this is not such a famous knife in Chen Xin's hand, it can be regarded as a good product.

The scabbard and handle can only be regarded as external decoration, which can be replaced at any time, and it is the blade itself that really determines whether a knife is good or bad.

Taking a deep breath, Chen Xin directly pulled out the love knife that he named Sakura Chori, wanting to see how his beloved knife had changed after upgrading.

With Chen Xin's movements, a section of the blade that slipped out of the scabbard was as black as ink, and there was no reflection like the scabbard.

This made Chen Xin a little surprised, this was the first time he had seen this kind of completely non-reflective blade, even this kind of pure black blade in the game was rare.

Standing the blade up in front of his eyes, Chen Xin carefully observed the part of the blade, stretched out his finger and touched it gently, he clearly felt the sharpness of the blade, and it seemed to have been carefully sharpened.

But even then, the blade was pitch black, as if the material itself was pitch black.

And what is a little strange is that the blade of the knife does not feel matte matte like a scabbard, but a very smooth mirror-like feeling, which makes Chen Xin quite surprised.
