Doomsday Drifting Begins with Shipbuilding

Chapter 159 Explosive Powder
Chen Xuan, who was preoccupied, left from the mission hall.

Wait for the last day, if there is no news from Xu Qing, I must act.

At this moment, he suddenly found a group of people nearby gathered together, discussing something excitedly.

"Why is there such a large demand for gelatinous algae recently? I see that the reward points have increased, and I want to go to sea."

"Brother, don't think about it, there will be no market for people like you."

"And it's not called gelatinous algae anymore, you are old Huangli, the correct name now should be gelatinous algae."

"I know the reason. It seems that the Institute of Chemical Engineering has made a new breakthrough. It seems that a new type of weapon has been invented, and it should be popularized by all staff soon."

"I've also heard about it. It seems to be called an incendiary bomb. According to people who have seen the experiment with their own eyes, the lethality of this thing is terrifying. The power of the flames that erupt is not a joke."

"Could it be that our good days are finally coming? I have to be careful with evolutionary beasts all day long, and I'm about to throw up."

"Hot Weapon, is it finally going to be revived?"

"TNND, those sea beasts, I don't like them a long time ago."

"Thinking about you too much, no one can deal with sea beasts now, even if you can bring back a fragment of a self-destructing fish, I will convince you."

……

Hearing the content of the discussion, Chen Xuan smiled slightly.

A few days ago, he submitted the information of the gel, and now it seems that the people in the research institute have researched the specific usage.

Did not live up to their hopes.

Although he has always understood the use of gel, his application method of gel is too crude.

And if they are professionals, they may be able to make the best use of it and develop more ways of using it, which is much better than groping for it by themselves.

I don't know what inventions the current Chemical Research Institute has.

Seeing that it was getting late, Chen Xuan quickly returned to the "Kunpeng".

……

At night, Chen Xuan was deep in thought.

In front of his eyes was the self-explosive fish carcass obtained during the day.

Previously, after the self-explosive fish was punctured, the chemical substances in it flowed out, and these dark red chemical substances were the key to the explosion.

Although he tried his best to rescue them, there were still not many left.

These substances had been extracted by him during the day, and now after leaving the water, they gradually dried up, exuding a strong pungent smell, like sulfur.

And Chen Xuan has already scanned it.

------

Name: explosive powder

Type: special material

Features: Extracted from the body of the self-explosive fish, the appearance is dark red. This substance will explode after receiving severe impact and high temperature. The body temperature of the self-explosive fish will rise when swimming, and the self-explosion is completed in this way.

Weaknesses: Please store carefully, avoid shock and high temperature.

------

Although I understand what these explosive powders are, how to use them is really a problem.

According to the description, this is simply a bag of explosives that I carry with me, and I accidentally blew myself up.

And it must not be stored close to the body. If the body temperature rises, it may cause an explosion.

Good stuff, but cumbersome to use.

Originally, Chen Xuan thought that he could add some means of attacking himself, but now it doesn't seem to work.

In addition, today's underwater search mission made Chen Xuan realize that besides combat equipment, he still lacks one thing.

Portable backpack.

It is really inconvenient to travel with bare hands every time, and the way of wrapping things in fishing nets is gradually becoming unsuitable.

Just like when collecting self-explosive fish carcasses before, they could only be temporarily packaged.

Moreover, after diving into the deep sea, I have to hold a light stick, which makes it difficult to move.

Maybe I should make a backpack myself.

With a backpack, it will be much more convenient to perform various tasks in the future. It can not only store items, but also serve as a quiver, killing two birds with one stone.

Although, you can buy all kinds of backpacks on the North Wind Plateau, and they have powerful performance.

However, Chen Xuan still plans to make one by himself, he is confident that the things after system optimization will definitely not be inferior to those backpacks.

After the leather armor was made from the snake skin of the poisonous python, there were still some leftovers, which were just used to make a backpack.

Back on the "Kunpeng", Chen Xuan turned out the previous snake skin, a layer of outer skin and a layer of inner membrane.

There is nothing to say about the material of the snake skin, its toughness and water resistance are currently top-notch.

The key lies in the design of the backpack.

How to ensure tightness even underwater.

Although the "manual expert module" can be optimized, it must also have a basic design.

After thinking about it for a while, Chen Xuan finally decided to adopt the design of drawstring pockets, which is more convenient to use.

After finalizing the plan, Chen Xuan started to do it.

Rolled the inner membrane of the snake skin with gel into the shape of a backpack, and then Chen Xuan made a drawstring design on it with a stretchable rope.

Finally, Chen Xuan made a side pocket on it to store weapons, which can be accessed at any time when necessary.

Then Chen Xuan wrapped a layer of snake skin on it.

The toughness of the snakeskin is good. After adding this layer of snakeskin, the backpack can also be used as a defensive shield, and it should even be good for temporarily catching some fish.

With the toughness of snake skin, the fish that is put in should not be able to break free and escape. Even if it is a self-explosive fish, it is estimated that it is not so easy to break the defense.

After finishing the backpack, Chen Xuan handed it over to system optimization, and a yellow light flickered on the backpack.

Everything is as he expected.

While waiting, Chen Xuan began to practice gymnastics over and over again, absorbing external energy.

After about two hours, the yellow light on the backpack gradually dimmed.

Seeing this, Chen Xuan quickly washed his hands and face, and then prayed sincerely.

"The first optimization of the snakeskin backpack is completed, and the effect protection is increased! (The items put in the snakeskin backpack will be protected and will not change.)"

Protection, this effect seems to be able to prevent the contents of the backpack from being damaged.

There will be no change, it should be able to ensure that the item is not damaged.

It's not bad, as long as it doesn't have the toughness effect, he will be satisfied.

If Chen Xuan carries something that is fragile or cannot be bumped, this backpack is very suitable as a container.

The shape of the backpack is similar to a large mountaineering bag, but the snake scales on the skin add a touch of luxury to the backpack.

Chen Xuan tried it on his back. The snakeskin itself is very heavy, but after being refined by the system, it is much lighter. It feels like an ordinary backpack when carried.

The top of the bag was also tied very tightly. Chen Xuan tried to throw the bag into the water and soaked it for about half an hour. However, it was still dry inside and no water had entered.

In the end, the optimization of the snakeskin backpack made the upgrade progress of the "Manual Expert Module" reach 85%.

It is very close to upgrade.

Maybe we should get more special materials and fill up the progress in one go.

Just in time, it is time for Professor Zhang Yongqing's letter to play a role.
