Chapter 181 Contract Alchemy Workshop 【Subscription】

"Flammable oil mixture."

"After the bottle shatters, it will detonate and produce a flame with strong adhesion."

Unlike Hutos Youji who was stunned, the iron idiot Wamish standing behind was obviously calmer.

There is even a summary of the effects of Molotov cocktails.

Chen Xuan turned to look at him, Wamish grinned, pulled the scar on his face, and showed an ugly smile.

I have to say that this guy summed it up pretty well.

Since both gasoline and alcohol-based fuels are volatile, after they are fully mixed, the relatively sealed bottle will be filled with flammable gas.

But after the incendiary bottle is ignited and the throw is broken, the flammable gas close to the compressed environment will deflagrate, thereby quickly igniting the oil scattered around the drop point.

That's why he didn't fill the whole bottle with oil.

The gorgeous flame burned on the metal target for several minutes before it gradually dissipated.

The range of influence of the flame is almost five or six meters in radius.

Hutos Youji couldn't wait to bring several alchemists in the alchemy workshop to the shooting range.

In fact, this guy himself is a multi-material scholar in alchemy.

Major sub-disciplines including mechanical engineering, material alchemy, and pharmacy have been involved, and they have all obtained titles certified by the kingdom.

After studying for a long time, it returned to Chen Xuan with a thoughtful face.

Those alchemists gathered together and discussed in a low voice.

"These oils you prepared are very special."

"Its combustion characteristics are very stable, unlike most flammable fluids known on Naroa."

"Mr. Chen...xuan...xuan, can you tell me the origin of these oils?"

Hutos Oil Machine quickly came to a conclusion.

It said Chen Xuan's name with a bit of a mouthful, and was very curious about the origin of the oil used to make the Molotov cocktail.

In fact, there are many kinds of oil that can be ignited on the Naloa Continent.

But there are very few with deflagration characteristics.

Usually alchemists like to add magic ingredients to achieve the desired effect.

For example, the main material of the "flame pot" that the Molotov cocktail is aimed at is the powder of fire element gems and the oil of fire monsters. As long as the input of magic element is activated, it can detonate the flames and burn.

In terms of combustion effect alone, it is better than Molotov cocktails, but the cost is very high.

Although the powder of elemental gems is leftovers, the quantity is not much.

And the fat under the skin of a fire fox can only make about eight or nine flame jars.

Not to mention that there is a risk of overturning during production. If you are not careful, the two bursting fire-type materials will ignite prematurely and cause an accident.

On the other hand, the Molotov cocktail brought by Chen Xuan is not only easy to prepare, but the risk in the production process is also very low.

Therefore, Hutos Youji is not interested in the process, but more interested in the mixed oil itself.

Flammable oils and fats are plentiful both in Naloa and Bluestar.

The most typical example is vegetable oil.

The essential edible oil in Blue Star's home is also a kind of flammable oil itself.

It's just that the ignition point of most edible oils must reach more than 200 degrees Celsius to ignite an open flame.

When used as fuel for lamps, it is easier to burn locally.

And solid edible oils, such as animal fats, also have similar characteristics, and will produce pyrolysis and combustion effects after entering the melting and boiling point.

Therefore, flammable fuel oil is actually not a rare thing.

At this time, it involves a concept that often appears in hazardous chemicals:

Flash point, fire point, spontaneous ignition point.

Liquids like gasoline are known to evaporate, and the higher the temperature, the faster the evaporation rate.

When the volatilized octane and cycloalkane vapors of olefins are mixed with air, sparks can be flashed when they come into contact with the fire source, but they can be extinguished in a flash and cannot continue to burn. This phenomenon is called flash ignition.

Under the condition of indoor temperature of 28°C and relative humidity of 85%, the evaporation rate of gasoline is 20% after 55 minutes.

At room temperature, 1 kg of gasoline volatilizes to produce about 400 liters of gasoline vapor.

When gasoline vapor is mixed with air evenly, the burning speed is extremely fast and the combustion is complete.

The second is the concept of burning point.

Whether solid, liquid or gaseous combustible substances exist together with air, when they reach a certain temperature, they will burn when they come into contact with the fire source, and continue to burn after the fire source is removed.

At this time, the lowest temperature of the combustible substance is called the ignition point, also known as the ignition point.

A key difference between ignition point and flash point is the ability to continue burning after the spark is removed.

According to the definition of flash point and fire point, for flammable liquids, fire point is higher than flash point.

The last is the spontaneous ignition point.

At the autoignition temperature, combustible substances can burn without the action of an open flame when they come into contact with air.

The self-ignition point of gasoline at normal atmospheric pressure is 427°C, but in the environment of compressed air, its self-ignition point can be greatly reduced.

It is the difference in the three characteristics of flash point, ignition point, and spontaneous ignition point that makes the biggest difference between gasoline and alcohol-based fuels and the common oils in the Naroa continent!

Hutos Oil Ji also saw through this point, so he turned his attention to the oil itself.

Facing its questioning, Chen Xuan smiled without saying a word.

"Mr. Hutos, this is a real secret."

"And I'm not here to discuss material alchemy with you."

"I just want the alchemy workshop to help with processing."

"The Molotov cocktails produced will be used to resist evil disasters."

Hearing his words, Hutos smiled sarcastically, knowing that he was being abrupt.

Any kind of mysterious material will not easily reveal its source.

For example, the Naloa continent is extremely vast, and there are some special materials everywhere, which will never be leaked as patents.

In its view, these flammable fuels that can be used to make Molotov cocktails must also have certain techniques and raw material sites that need to be kept secret.

It is absolutely unexpected that these materials are common fuels in another world.

Seeing the change in Hutos' expression, Chen Xuan could roughly guess what this guy was thinking.

When it was about to speak, Chen Xuan suddenly changed the topic.

"However, this matter is not completely unnegotiable."

"Oh? You can put forward any conditions you have."

"Whether you want Krona, alchemy materials or potions, as long as you open your mouth, everything is easy to discuss!"

Hutos Youji rubbed his hands together, and expressed his attitude with anticipation.

Talking about business is one of its areas of expertise.

As long as the other party let go, then there is hope for the negotiation.

But Chen Xuan grinned.

"My terms are simple,"

"As long as you sign a time-limited slave contract with me with all the alchemists in the alchemy workshop who have the titles of three-level mechanical engineering, material alchemy, and pharmacy, then I will tell you all about the origin of these oils."

Chen Xuan used greed as his thread and oil as his bait, sitting by the river, fishing for these goblin alchemists.

This condition stunned Huto for a moment.

"Slave...slave contract..."

His sensitive and suspicious nature makes him think that this matter is not simple.

"It's time-limited!"

Chen Xuan took the initiative to add a sentence.

At this time, Hutos Youji looked at the backbones of the alchemy workshop behind him, bowed slightly and gave a salute, and replied in a hesitant tone: "Please wait a moment, I need to discuss with my fellows! "

After they finished speaking, they jogged together for a while, and began to discuss in whispers.

And when Chen Xuan finished talking about the time-limited contract, the embarrassment on Jason Iron Furnace's face flashed away, and Tie Chi Womish turned around and looked at the chariot not far away, with a focused and serious expression, as if he didn't care about Chen Xuan. Xuan's request to the goblins.

A few minutes later, Hutos Youji returned to Chen Xuan.

"As you said, it is not impossible to conclude a time-limited slave contract."

"But the terms of the contract must be drawn up and initiated by us."

"And the duration of the contract can only be one Naloa day at most!"

Hutos's tone was very firm, his eyeballs kept rolling, and the speed of eye movement was directly proportional to the speed of thinking. He didn't know how many thoughts he had already turned in the time he said a few words.

"can."

Chen Xuan readily agreed.

The time limit was a pretense.

Besides, with the current catastrophe in Magtan City, no one is sure whether they can survive until the next Naroya Day.

Haggling all the time at this juncture, not only could not conceal his true intentions, on the contrary, he wanted to cover it up a bit, as if he took off his pants and farted.

So Chen Xuan readily agreed.

Soon, under the urging of Hutos, a goblin engineer named Quentin Flowerpi reluctantly came out first, and sent Chen Xuan an invitation to make a contract.

Hutos was also very cautious, knowing to let the guys test the water first to see if the contract was tricky.

Little did they know that Chen Xuan's contract modification would only take effect after [Crossover], how could it be so easily exposed.

The contract appeared in the minds of both parties, and his consciousness quickly interpreted all the terms.

No loopholes that could force the termination of the contractual relationship were found.

It's just that the other party set extremely strict restrictions on both parties in the slave contract.

As the master, Chen Xuan was not only unable to force orders, but the goblins also had the right to refuse to answer questions.

In addition, there are a series of supplementary instructions.

This makes the so-called slave contract exist in name only, and is closer to the cooperative contract in essence.

But it doesn't matter, Goldfinger will make a move, and the clever behavior of the goblins will hardly change the fate of being eventually recruited by Chen Xuan.

After choosing to conclude and leaving a soul mark, the master-servant contract relationship between the two parties is established.

Seeing that the process of signing the contract went smoothly, Hutos Youji finally let go of his guard.

It led other alchemists to accept Chen Xuan's contract successively.

In this way, the alchemy workshop in Magtan City was taken under his command.

Not busy with [Crossover], Chen Xuan introduced the origin of gasoline and alcohol-based fuels to Hutos as agreed, as well as the introduction of petroleum, a fossil fuel.

Since the conversation involved confidentiality, Chen Xuan and the goblins went to the office to have a conversation.

After he finished speaking, these alchemists with high-level professional titles fell silent.

But the silence didn't last long.

A goblin alchemist sitting next to him suddenly raised his hand, and Chen Xuan nodded, indicating that it could speak.

"According to the description, does this oil look like the mud that was recorded in the Biological History of Naroa?"

"It is rumored that there are several mud lakes in the wild basin where the trolls live."

"The ground slurry is very viscous and cannot be ignited directly, but there are often flammable gases floating on the surface of the lake."

"One of the magma lakes was ignited on a large scale in more than 200 Naroa years, and the flame has been burning until now."

Its words quickly elicited responses from the other goblins.

Even Chen Xuan narrowed his eyes.

Judging from the description of this goblin alchemist, the ground slurry is really a bit like oil.

And the place where it appears is a basin, which is also in line with the oil-rich topography.

In Blue Star, most of the areas rich in oil resources are mostly sedimentary terrains, such as plains and basins.

The desert basins of the big dogs in the Middle East, and even the cracks and cracks in the ground can overflow oil.

In addition to being full of magical power, the Naloa continent has many things in common with blue stars in terms of environment. It is not too strange that oil resources will be born.

"Okay, let's not talk about the topic of oil for now."

"The most important thing right now is to manufacture Molotov cocktails."

"I have just finished talking about the manufacturing process and fuel ratio."

"I need to get at least 3500 Molotov cocktails in seven water clock hours."

"As long as I can survive the disaster, I will find a way to get some crude oil and its derivatives for you to study."

Chen Xuan raised his hand and tapped on the table lightly.

All the goblins stood up and saluted.

Although the contract has not been revised yet, the master-servant relationship between the two parties has been confirmed.

Then all the goblins followed Chen Xuan out of the office.

When he came to the venue, he took out gasoline and alcohol-based fuel from the storage compartment, as well as thousands of beer bottles.

As for the cloth strips, let the goblins figure out how to raise them themselves.

The agreed OEM fee is 3 crowns per Molotov cocktail, and the total agreed price is 10500 crowns.

A slave is a slave, and business is business.

The alchemy workshop will gather all the alchemy apprentices in the city, and allocate at least half of the workers to fill the Molotov cocktails.

After Chen Xuan finalized this matter, he felt a lot more at ease.

When he finished talking with the goblins, it was already half an hour later.

Unexpectedly, Tie Chi Wamish did not leave.

Instead, Jason Iron Furnace returned to the association with the blacksmith apprentices and the magic energy transporter first.

When Chen Xuan came out, Wamish walked towards him.

"Let's talk about a deal."

"Give me one of these chariots."

"It doesn't matter what condition you ask."

"I know you have a brand new material and mechanical engineering department technology."

"By the way, can I touch it?"

Tie Chi Wamish said in a calm tone, his hoarse voice made him appear even deeper.

And this guy has been looking at it for so long, but he hasn't touched it with his own hands. He has to ask the owner for permission before touching it. I don't know whether to call him dull or to say he obeys the rules.

Chen Xuan nodded, motioning for him to please.

I saw the iron idiot Womishi stretching out his huge alienated palm and gently sticking it to the side of the tank.

Red light bloomed from his palm, covering the entire tank in an instant.

At the same time, a hint of enlightenment flashed in his eyes.

The bloody light immediately subsided, and his expression became inexplicably complicated!
