The twelve houses were all upgraded quickly, and Qin Yu then used the remaining four gray fragments to upgrade the fence around Xiaofang Village.

Upgraded from the original [Fence with Only Wreckage] to [Broken Fence].

Finally erected a prototype.

After doing all this, Qin Yu returned to his residence.

His current house has also been upgraded.

The surrounding courtyard walls are no longer in dilapidation.

It was that gap, Qin Yu deliberately left it.

The black bear didn't come over in the past two days, although he didn't know if they would come back again, but Qin Yu still left a door for the little black briquette.

After all, the black bear has some spirituality, and his current silver spirit grass seeds were also sent by the black bear.

is reasonable, and it will not completely seal the courtyard wall.

After the upgrade, the people are indeed much more comfortable to live in.

Although the bed is still very hard, at least it is not a butt.

Qin Yu took a deep breath, he originally wanted to confirm his previous speculation tonight.

But the place where there was not even a candle was too dark, and after thinking about it, he could only forcibly press down his impulse and sleep first.

The next day.

Qin Yu opened his sour eyes and rubbed them for a long time, and then he finally felt better.

"I knew I could have done it last night, and I really appreciate my self-control."

Although Qin Yu didn't have a mobile phone, he also had a clock in his system interface.

Thinking of the exciting speculation in his heart, he was excited for most of the night, and he barely fell asleep until more than three o'clock in the morning.

This familiar routine made Qin Yu suddenly regain the feeling he had before the crossing.

However, unlike before the crossing, Qin Yu did not sleep until noon now.

Although he woke up much later than those villagers, it was really early by the standards of modern otaku.

Thinking of the guess last night, the sleepiness that Qin Yu had had before suddenly disappeared cleanly.

He glanced at the 100 gray fragments that had been refreshed, plus the 1 white fragment he had obtained from the broken entry yesterday, and then came to the small courtyard.

"Start with the most outrageous, let's try it first."

Qin Yu said to himself.

Then he went straight to the spear he had placed in the corner.

[Nearly scrapped spear]

【Upgradeable】

[After upgrading, the entry is promoted to ordinary]

[Upgrade needs to consume gray shards x1]

Not surprisingly, the description of the spear that Qin Yu saw was no different from before.

But......

Qin Yu was still holding the spear, but his eyes were closed, and then he muttered: "This is an eight-point steel gun!" ”

Then he opened his eyes.

[Completely scrapped Zhangbao steel gun]

【Upgradeable】

[After the entry is upgraded, it is promoted to almost scrap]

[Upgrade requires the consumption of blue shards x10]

"it!"

"It works!"

Qin Yu looked at the attribute entry in front of him that had been completely changed, and couldn't help it for a while, and laughed.

Qin Yu was indeed a little surprised that the eight-point steel gun could really be set.

But after the accident, there was ecstasy.

Since the eight-point steel gun can be stuck out in this way, doesn't that mean......

The things I don't know how to do can be stuck in a similar way?

Anyway, I didn't bring a militia survival manual with me when I crossed, and I was a scumbag myself.

Not to mention those high-end gadgets, I don't even know how to burn glass, but I don't know what to do after Haiyan is dry, but I don't know what to do after drying.

If this can be done, then ......

Wouldn't it be better for me to write a flawless recipe or to develop a flawed technique......

For example, improved papermaking, blast furnace steelmaking, and even firearms......

"Am I doing this a bug?"

Qin Yu's spirit completely relaxed.

"Even if it's a card bug, I admit it, this thing is easy to use!"

"It's just that I want to card this BUG doesn't seem simple.,It's just to upgrade a steel gun at eight points.,Now it's going to use up 10 blue shards.,If it's used to card something else.,I'm afraid it won't be so simple!"

"But after all, this is an idea, an opportunity with infinite possibilities!"

"In the future, we must seize this point and rush him! Let me change the world! ”

"But those things aren't necessary for me for the time being, so let's do it for now......"

He put the spear back in its place.

In fact, there will be such a discovery, and it is really thanks to Huang Zhong and their house yesterday.

Qin Yu had never thought that his golden finger could be used like this before.

It was at that time that a flash of inspiration suddenly appeared, and the current result appeared.

To put it bluntly, it's actually very simple, but ordinary people's thinking really doesn't rely on it out of thin air.

The basis of this idea is Huang Zhong's house, which is only half built.

Indeed, even though it was a very simple house made of twigs and something, it was indeed a house.

If it's a house, then Qin Yu will be able to upgrade it through the entry.

This has the ability to upgrade to [Dilapidated Houses] later.

If it was just a gray fragment, Qin Yu might not think much about it.

But it's so good that he can't die, this system actually needs him two gray fragments to upgrade to [Dilapidated Houses], and then one more gray fragments to upgrade to [Ordinary Houses].

Doesn't this make it clear to tell Qin Yu that there is something greasy in this?

Why do low-level entries cost more shards than higher-level upgrades?

As a player who likes to deduct resources at the beginning of the game, and pursues to use every bit of resources in the most suitable place without wasting anything.

Qin Yu instinctively stared at this wrong place.

Then, his thinking changed a little bit.

"Why is this hastily built out of rotten wood and branches called a house?"

"How can I upgrade it to a dilapidated dwelling with gray shards?"

"He has a dilapidated house, why dare he ask me for two gray pieces?"

"If you work backwards from this result, assuming that it is a reasonable demand for him to ask me for two gray fragments, then there must be something unreasonable in one of the previous rings."

The corners of Qin Yu's mouth hooked: "So, why is the thing that is piled up by rotten wood branches is a house?" Isn't that precisely because I think he's the house? ”

"I am the foundation that defines this world!"

"I think these rotten wood branches are houses, that's why he became a house, and I can use fragments to completely turn him into a house."

"Then what if I think this gun is not an ordinary gun, but a steel gun?"

It was with such an idea that Qin Yu would have the attempt he had just made.

As it turned out, he was right.

The name of the spear has indeed been changed out of thin air.

He does have a chance to turn this ordinary spear, which can no longer be ordinary, into a spear with a stronger essence!

It's just that the resources needed to consume are impossible for him to obtain now.

Even if you have a chance to get blue shards in the future.

Compared to the acquisition cost of 10 blue shards, it is much cheaper to directly build an eight-point steel gun.

However, it doesn't matter if it can be turned into a steel gun, what matters is the mechanism of the system!

As long as you understand this mechanism, there will be more routines that Qin Yu can play in the future!
