Super modification system

Chapter 40 Vault construction!
After completing the treasury, it is natural to start building heavy machine guns.

As the first defense tower he encountered in this game, he can only say that this thing is really strong after modification!
"Can't Ruoxue system use gold coins to exchange opportunities for modifications and enhancements?"

He was in a bit of trouble. If this defense was not modified, the damage would not increase at all. If, it should be said, if the snow monster attacked tonight, it would probably be smashed to pieces by the snow monster.

"Yes, after the base has been upgraded to level four, a new exchange function has been unlocked."

Open the blue electronic board, and there is another exchange under the resource and defense.

Different from the badge exchange, there are three kinds of currencies that can be used in it, namely gold coins, holy water and crystals.

Both the holy water and the crystal were gray, and the only thing he could open was the one with the words "gold coin exchange".

As soon as he opened it, he was immediately shocked. The most expensive inside were some rare defense towers, which cost a full 100 million gold coins, while the cheapest one was the one at the bottom—Endless Trial, fifty gold coins A gold coin is a challenge opportunity, and the one on the left is a modification opportunity, which requires a full [-] gold coins, and the last is a strengthening opportunity, which requires [-] gold coins.

With his current money, it's not that he can't afford it, but if he buys it, he will go back to Jiefangqi directly, which makes him very embarrassed.

Although the expression on his face was ugly, he still couldn't control his hand and clicked buy directly.

"Direct reinforcement and should be loaded with heavy machine guns."

This is a heavy machine gun. He built it behind the electromagnetic high-pressure water cannon, which is next to the scorching furnace. Focused on the front, it doesn't work at all.

Due to the strengthening, the construction time is directly exempted. Compared with the existing one, the newly built heavy machine gun has a smaller appearance. Every defensive construction will not be copied, and it will be upgraded one by one. Jiang Ruoli was a little annoyed.

If not, it is estimated that he has already upgraded all the city walls to the second level, not to mention the second level, it is possible to upgrade to the fourth or fifth level.

I stretched my waist, and now it started to snow again. Strange to say, since the event started, even during the day, it was almost the same as that night, making it hard to tell.

"Really, didn't I call you back long ago, meow!"

Seriously casting magic to expel the chill from his body, Felix couldn't help complaining a few words.

"No, it's nothing, anyway, it's still early, I'll build those that should be built first."

"Okay, it's getting late, go to bed early, Phyllis has installed a few more light stones in your room, and there is a point where the enchantment is also there, and it will be too cold at night meow!"

"Well, thank you."

In the house, he didn't feel any coldness at all. Felix had taught him how to turn off these light stones before, but since he didn't know how to use magic, Felix had to install a special one to control these light stones just for him. Lightstone switch.

Close your eyes, the room is extremely quiet, because Felix has set up an enchantment, the outside sound can't come in, and it's rare to have a good night's sleep.

"Ding, the defense is successful, kill 150 and three snow monsters, and get 530 gold coins."

"Ruoxue, can you tell me next time, otherwise it will be scary to hear this mechanical sound and this ding."

Lying on the bed, he just felt lazy all over. Felix's light stone was so easy to use. This warm feeling made him not want to get up from the bed at all.

"no way!"

Jiang Ruoxue looked very helpless, of course, Jiang Ruoli couldn't see, this appearance was completely imagined by him.

Now that he has enough money, he originally planned to use the contract scroll directly, but there is no other way, the rooms are simply not enough, if he wants to build a few more rooms, he can only demolish the base.

Speaking of which, he caused the trouble himself. He was worried that the base would be too big and take up space, so he didn't build it too big, so he built two rooms and a living room for eating.

Of course, this is not the only reason why the base is not built big. There is another reason, that is, if the base is built too big, it will be difficult to improve the defense. At the beginning, he also wanted to build the base a little bigger, so that it would look grand. But helplessly, the living environment and the body do not allow it, and this idea can only be obliterated in the cradle in the end.

Now he has no choice but to re-expand the base. A few nights ago, he asked Jiang Ruoxue this question, and the answer he got was - only increase height, no expansion!

It is not out of the question if you want to build a few more rooms, but it is necessary to add two floors to the base, which is even more troublesome, so it is better to wait until later.

These snow monsters still refused to give up at night, and the "ding ding" sound of the system kept appearing in his ears, torturing him to the point of collapse.

It wasn't until dawn that Jiang Ruoxue kindly reminded him that in fact, ten gold coins can be spent to turn off the notification sound, and when it is turned on, it will also cost ten gold coins.

"Morning, Phyllis."

With two inconspicuous dark circles under his eyes, he looked very listless.

"What's wrong with you, meow?"

Seeing his appearance, Felix was very puzzled, logically speaking, it shouldn't be like this.

"No, that is, I didn't know how to turn off the system's notification tone last night. It rang all night, and I didn't know how to turn it off until this morning."

"You are really not careful, you have to pay attention next time meow!"

Felix didn't ask much, and began to perform healing techniques for him.

Felix's healing technique can basically be said to be omnipotent, not only can heal injuries, but also recover mental fatigue.

"It's much better now, Phyllis!"

Stretching, the feeling just now was too uncomfortable, and my whole head was groggy.

Although before time travel, he was really a poor student in the class, but he usually pays attention to it, and basically doesn't stay up late, last night can be said to be the first time he stayed up all night.

He earned nearly 2000 gold coins last night, plus the previous ones, he still has more than [-] gold coins in his hand.

With money in his hands, what he has to do is to save the construction time to complete in an instant, otherwise it will be too troublesome.

"Upgrade the giant electromagnetic tower!"

"Upgrade the super heavy machine gun!"

"Upgrade the mortar!"

"Upgrade Lava Thrower!"

……

He finally had a rare experience of the refreshing feeling of building in seconds. It took him a morning to upgrade the two heavy machine guns to level five, along with the mortar cannon, electromagnetic high-pressure water cannon, and giant electromagnetic tower to level three. Defense is level [-].

Originally, he planned to set those defenses to the third level like the mortar cannon, but he suddenly found that his wallet was completely emptied by himself.

"Ruoxue, that's not right, I spent so much money, logically speaking, I should be at least level three, why didn't I hear..."

Before he finished speaking, he realized one thing - he had turned off the notification sound.

He checked some of his wallets, and there were still ten gold coins, but helplessly, his wallet was completely emptied. As a price, he finally heard the notification sound.

"Ding, the level has been raised to level three."

"Ding, the level has been raised to level four."

"Ding, the vault is built."

Building: Treasury

Capacity: [-]

Introduction: A huge solid iron box can help you keep these gleaming gold properly. After all, you don’t want your wealth to be peeped at, right?
The gold coins rewarded by the system level promotion had already been used up by him without anyone noticing.

Originally thought that the system would give some rewards, but looking at the eternal zero, he couldn't even smile.

"Ruoxue, didn't you say that there are icemen and ice sharks? It's the second day, and I haven't even seen a single shadow, not to mention ice sharks, and I haven't even seen an iceman?"

He was a little puzzled, logically speaking, it was the next day, no matter what, those icemen should show their faces, no matter what, they couldn't even see a shadow.
