Doomsday: My Shelter Unlimited Upgrades

If they want to abandon Lin Tian's guns and use others instead.

Then the cost of buying Lin Tian guns before is equivalent to wasting money.

In the last days when every resource is extremely precious, there are absolutely not many people with such courage.

So, these people have only one choice.

That is to continue to use Lin Tian's guns and continue to buy Lin Tian's ammunition.

At the same time, they will comfort themselves in their hearts.

Anyway, the price of ammunition is not very expensive, and I can afford it. If I spend a lot of money to rebuild a gun, then the current gun will be wasted.

This is a sunk cost!
If you follow this plan, you will definitely make a lot of money!

Lin Tian couldn't help but get excited.

But immediately, he suppressed the excitement in his heart.

This matter requires a long-term plan.

Most importantly, there is also a lizard warrior's broadsword in his warehouse.

Trade this broadsword too!

Without hesitation, Lin Tian immediately put another broadsword on the transaction list.

"Trading Item: Lizardman Warrior's Broadsword (Excellent)"

"Required items: private chat, gunpowder first."

"Introduction: None"

After putting the broad sword on the shelves, he opened the chat interface and advertised.

"The artifact broadsword, there is only the last one left, if you want to buy it, hurry up!"

However, after seeing Lin Tian's words, the survivors exploded.

"Seeing that Brother Lin Tian only hung out a broad sword, he thought there was only one, and this is a loss!"

The Survivor who just bought the Broadsword jumped out immediately, with a remorseful look on his face.

It was precisely because he thought there was only one broadsword that he offered such a high price.

After all, what is rare is more expensive.

A rare item, no matter how weak it is, will always be bought at a high price.

And a public item, no matter how strong it is, will only be reduced to a "cost-effective" item.

Can't sell.

This is why Lin Tian didn't list them together.

Ignoring the message on the chat interface, he opened the private chat.

After he posted his second deal, private chats started to heat up again.

Because this time he specifically wrote that he needed gunpowder in the required items, so there were abnormally many bids with gunpowder in this private chat.

It's just that although there are many people who own gunpowder.

However, the amount of gunpowder in each person's hands is not too much.

After searching for a while, Lin Tiancai found a survivor with a lot of gunpowder in his hand.

15KG gunpowder!

This is definitely a great price!
Without hesitation, Lin Tian accepted the other party's offer in an instant.

With the completion of the transaction, there were 15KG more flames in his warehouse.

Plus the 10KG gunpowder obtained from the previous transaction, and other gunpowder obtained sporadically.

At this moment, he already has a whole 30kg of gunpowder in his warehouse!

Not much to say.

If you make bullets, you can only make about [-] rounds.

However, this amount is definitely not small!
With the 30KG gunpowder, he can use the gunpowder to make bullets, and then obtain gunpowder continuously through the bullets.

Virtuous circle!
With a look of joy on his face, Lin Tian happily shut down the system and stood up from the bed.

Go build the wall first!
Lin Tian walked out of the wooden house while thinking.

The area occupied by the oil field is not too large.

He also does not plan to make the land circle too large.

On the one hand, it was because the wall was built too long, and he couldn't manage it alone during the defense.

The more important reason is that he must build the wall as soon as possible.

The bigger the project, the more time it will take.

However, no one knows when the lizardmen will attack.

Build as fast as possible!

Taking out the stone from the warehouse, Lin Tian did not use the system, but built it manually.

As he continued to survive, he felt more and more the importance of survival points.

Strengthening requires the consumption of Survival Points, and manufacturing requires Survival Points.

The survival points settled every day are simply not enough.

Must live within our means!

Except for some necessary expenses, if you can use the survival points, you don't need the survival points.

If you can rub it with your hands, rub it with your hands!
As Lin Tian was thinking, he kept pounding stones on the land around the oil field.

This step is to ram the foundation.

Because, he observed, the ground under his feet was too loose!

With a light hit, the stone sank ten centimeters into the ground!

Such loose soil must be compacted to build!
If the foundation is weak, the ground will shake.

No matter what you build, the foundation is very important.

Without a solid foundation, the building above is like a plant without roots.

Such as flood disasters.

Without a solid foundation, it will sink irregularly under the erosion of running water.

Correspondingly, there will be corresponding cracks in the buildings above.

If the subsidence is severe, the buildings above will collapse.

Therefore, in order to build, the foundation must be solidified first.

Even if it is to build a wall, Lin Tian is still very serious and refuses to be sloppy.

Ten minutes later, Lin Tian's forehead was covered with sweat.

However, he still hugged the stone and slammed it on the ground.

In this way, half an hour passed.

He finally straightened up and wiped his sweat.
