Chapter 73 The Miraculous Warm-Blooded Fish Skin

Su Jin quickly withdrew one of his throwing axes; he had really been tempted to throw it just now.

Although the axe wasn't aimed at Old Zhang's face, but only swung near him to scare him, it did make him a little red-hot.

He made a bunch of demands right in front of him, which almost reminded Su Jin of some idiots on the internet who couldn't understand human language.

He hates talking to people like this more than anything else in his life. He'd kick one to death if he saw one. These people must have been possessed by aliens.

He suppressed his anger and said coldly:

"Based on your conditions, for this deep-sea clam pearl, I can only offer you 30 units of wood at most; you'll have to exchange other items for the rest."

Thirty units of timber was already a lot; he would have to chop three whole trees for firewood, and that would be all the timber he had left on his ship.

Upon hearing that Su Jin was willing to give him 30 units of wood, Old Zhang was overjoyed and thanked him profusely.

With this wood, plus the stones he'd collected and the logs he'd chopped over the past few days, he could gather enough for 50 units of wood and 10 units of stone to upgrade his island.

Soon, he will have his own place to live and will be living a comfortable life!

Of course, the other things he mentioned earlier were also very important, so he spared no expense and brought out all the treasures he had caught during this period.

He rummaged around in his clothes and pulled out a grayish-white, rag-like object from his pocket.

"This is a piece of skin shed by a deep-sea warm-blooded fish. Don't underestimate its ordinary appearance; it actually has great uses."

"Through my experiments, I found that it has a similar effect to quicklime. Once it comes into contact with water, it will absorb water and boil, generating a large amount of heat."

"Please take a look, sir."

As he spoke, Old Zhang took out the bucket that Su Jin had given him earlier, filled it with icy seawater, and then threw the warm-blooded fish skin into it.

Just as he said, the fish skin swelled slightly the moment it came into contact with the water, and then soon the water started bubbling.

Less than two minutes later, the bucket of seawater began to boil, constantly emitting steam.

Moreover, if you look closely, the seawater in the bucket is actually quite clear, so it's clear that the warm-blooded fish skin didn't have much of an impact on the water quality.

Su Jin's eyes lit up when he saw this, and he clicked his tongue in amazement:

"I never imagined there were such marine creatures in the ocean, but if it were quicklime..."

He glanced back at the surrounding archipelago, his gaze settling on the island where Old Black had been.

"Look at this island. The mountains are grayish-white. It's obviously rich in limestone. Even if it's not here, limestone is a byproduct of some mineral veins and is easy to find."

He glanced at the still-steaming, bloody fish skin that Old Zhang had fished out, and said calmly:

"If your thing doesn't have anything particularly special about it, it's just for easy storage and isn't very valuable."

Old Zhang naturally understood this principle, and he quickly explained:

"The skin of this warm-blooded fish is special because it can be reused."

"Look, boss, I squeezed out the moisture from this warm-blooded fish skin, and then, because of its high temperature, it evaporated quickly. Once it's dry..."

As soon as he finished speaking, the warm-blooded fish skin in his hand began to shrink.

"It will probably return to its normal size after a while, depending on the heat it absorbs."

"As long as it absorbs enough heat, it will quickly return to its original state, thus achieving a state of recycling. And look, boss..."

He flipped the warm-blooded fish skin over; this side was a deep black, a distinct color from the previous side.

"That side was the inside of the warm-blooded fish, this side is its skin, the two sides are different."

"This side of its skin is waterproof, and it will not generate heat when it comes into contact with water. This is its inherent characteristic."

"They usually live near lava fields, absorbing heat when they have nothing to do and releasing heat when they get cold. They live a very comfortable life on the seabed."

Su Jin nodded, a look of understanding on his face.

That makes sense. Otherwise, he said that this kind of fish is constantly releasing heat in the water. Where does the heat come from? So that's how it is.

Even without Lao Zhang saying it, he could figure out the uses of this warm-blooded fish skin.

First of all, it is definitely a good alternative to self-heating hot pot packs. You don't need a kettle or a fire to boil water; just throw it into the water.

After boiling the water, squeeze out the excess water, and let it dry on the deck for a while before you can use it again. It's pretty good.

Of course, due to its waterproof properties, it can also be made into a kettle.

If you want to drink hot water, just pour water in, let it sit for 30 seconds, and then pour it out.

It can even be used as a hand warmer after boiling water.

In addition, by pouring in only a little water and then immediately pouring it out and squeezing out the excess water, it can be used in batches before the stored heat is completely dissipated.

Sometimes, when they're warming themselves by the fire, they'll place it near the fire to absorb some of the excess heat, thus avoiding any waste of heat.

In any case, anything that can be recycled has great value.

Especially with the cold wave approaching, items that can provide heat in a circulating manner are extremely valuable.

Su Jin also thought that if the seawater desalination device he built later froze, he could put a piece of this stuff in from time to time, which would perfectly solve the problem.

A heat source with very few restrictions and no risk of open flame is truly a good thing!

"Great, great, this stuff is really good, I'll take as many as you have!"

Su Jin immediately took a liking to the item and boldly declared his intention to purchase it at a high price.

Old Zhang's face lit up with joy. Finally, something good had caught the eye of the big boss. It was no easy feat.

"There are nine of these in total, they're all yours, sir!"

Actually, he had 10 cards in total, and he had to keep one for himself.

However, Su Jin didn't care about the other party's ulterior motives. He would take as much as he could, since it was definitely a profitable deal.

He stroked his chin, calculating the price.

"A piece of warm-blooded fish skin is a small item, worth about 10 units of wood. Based on the conditions you provided, I can fulfill most of your request, but..."

He smiled at Old Zhang and said:

"Don't forget you still owe me half an axe. I suggest you bring out everything you want to trade, and I'll refund any shortfall and make up any extra. You definitely won't lose out."

Old Zhang's eye twitched. He felt that Su Jin was determined to squeeze him dry today, but he was really short of supplies.

He gritted his teeth and said:

"There's also something I use myself, an unknown deep-sea barnacle gel, which can be used to stop bleeding."

"The dead, cold jellyfish, it's ice blue anyway, and it tastes like mint. It should be very effective for cooling down and relieving pain. That's all, nothing else."

He originally intended to keep both items for himself, but since he didn't need them much right now, he had no choice but to put them up for trade.

Su Jin nodded with great satisfaction; both items were excellent. He then waved his hand and said:

"Okay, I'll fulfill all your requests, and then we'll be even. Besides, this is a good deal; we're partners, so I've reserved a business class ticket for you."

"Welcome aboard the Ark in the future."

Old Zhang nodded excitedly, but in reality, he didn't really care about the boat ticket.

He is about to achieve a comfortable standard of living, and with his talent, he will surely get better gradually.

The two quickly began trading their goods, and Old Zhang, looking at the pile of supplies, almost wanted to burst into laughter.

Clearly, this was a huge win for him, considering all he had to do was spend a little time fishing.

But for Su Jin, this was a real windfall.

The most precious thing is not the warm-blooded fish skin, but the deep-sea pearl from the very beginning!

He gently touched the deep-sea pearl, and immediately received a system notification.
