Late at night, the survivors' camp was completely silent.

Most of the natives had fallen asleep,

Only a few sentries on duty were still standing behind the fortifications, patrolling back and forth.

They each held a cigarette in their hands and puffed out smoke,

Their eyes, wrapped in thick turbans, narrowed slightly, and looked curiously into the distance.

One kilometer southeast of the camp, a blue pickup truck quietly pulled over and turned off the engine,

The newbies stood in a row beside the car like elementary school monks.

Five pairs of eyes stared at the various instruments and equipment in front of them, all speechless and choking.

Small stamping machine, handheld electric saw, curved neck bottle, acid mixing cylinder, crucible, steamer, U-shaped tube...

The front looked quite normal, all of which were commonly used experimental equipment in chemistry classes in ordinary universities.

But what the hell was the big bag of light yellow crystalline substance in the back, it felt very disturbing.

And the oily liquid in the sealed glass jar was sulfuric acid, right?

The H₂SO₄ label on it was not torn off!

Yan Shuihan, the only one who was not standing in the queue, remained silent at this time.

As early as before the transmission, when he received the purchase list handed over by Qin Nuo, he felt something was wrong.

Cigarettes, alcohol, melon seeds and peanuts,

These daily necessities are understandable.

Toluene, nitric acid, mercury, alcohol, etc. are very suspicious.

"He wrote the list because he was sure that my family was big and had channels to buy a large number of controlled items in a short period of time."

Yan Shuihan silently glanced at Qin Nuo with a complicated look.

The latter pretended not to see it,

Flipping the hem of the bird-beaked doctor's robe, he said loudly:

"Dear new players,

Based on the strategic tone of mutual assistance, unity and friendship, and the Belt and Road Initiative to achieve common prosperity,

As the owner of the store No. 2234, Sanhuan, Game Plaza, I have decided to conduct emergency armed training for you."

He took out a mobile bracket whiteboard from the backpack column,

picked up an oil pen and wrote a few words on it-

How can new players get high task evaluations in the early stage?

After writing, he put his hands behind his back,

pointed at Lu Renjia with his chin, meaning that you should answer.

"Uh... clear mind, meticulous logic, calm... ah!"

An oil pen hit his forehead accurately like a dart,

Lu Renjia immediately covered his head and squatted down in pain.

"Except for a few special talents who have received professional training, how many new players can meet your requirements?

Even among the old players, there are many who are not smart."

Qin Nuo took out a pen from his pocket again,

turned around and wrote two big words on the whiteboard - Krypton Gold.

"As the saying goes, a strong man can fly bricks,

The difference between starting with a +15 Dragon Slaying Sword and starting with a small wooden sword is a world of difference.

Similarly,

If new players are equipped with sufficient firepower when going to the dungeon,

they can make up for the shortcomings of low basic panel values ​​and insufficient mission execution experience,

thus obtaining a high mission evaluation.

Take the Rick Town we experienced during the day as an example,

If each of you has a Vulcan cannon, fully equipped with anti-material sniper rifles, and B-type pineapple bullets,

will you still be afraid of cricket zombies?"

As soon as the voice fell,

Gao Wenwen raised her right hand and asked: "Boss, what you said are all hot weapons in the real world.

We read the post online It is said in the article that players should not buy finished guns and ammunition to play the script, otherwise they will be punished implicitly by the system. For example, if you encounter a ghost with bullets invalidated, you will be forced to play a role, block your backpack, etc. " "Yes, that's why you are called here." Qin Nuo pointed to the rich variety of chemical equipment in front of him and said in a deep voice: "It is true that the system restricts the carrying of finished hot weapons, but it does not prohibit players from DIY. As long as you have a certain amount of knowledge and a junior high school monk's hands-on level, you can easily solve the problem of insufficient firepower in the early stage. " The white firefighter Han Meimei probably understood what to do, and his face turned ugly instantly. Although he came from the United States where guns are legalized, and he has touched real guns at the shooting range. But rubbing explosives with your hands...isn't it too dangerous? What if it explodes? There was not much protection loss at the scene. The other newbies saw that Qin Nuo was in trouble and immediately wanted to escape. Makkabaka,

We just want to complete the mission safely, there is no need to torture us like this, right?

Gao Wenwen tightened the sleeves of her sportswear, secretly cheering herself up and hypnotizing herself.

After whispering for a few seconds,

Xiao Bingyi raised his hand tremblingly: "Boss, the pressure is too great, can I not play?"

"Not play?!" Qin Nuo raised his eyebrows and swung his arm violently.

The oil pen turned into Xiao Li's flying knife, piercing the opponent's sensitive parts quickly and accurately.Then Xiao Bingyi shrank into a shrimp, fell to the ground and howled.

"I have worked so hard to teach you, and you have the guts to say you don't want to play?

Stand still!"

With the order,

the remaining four people were like frightened birds, quickly adjusted their stance and dared not move at all.

"You cheap bastard."

Qin Nuo snorted coldly,

took out a pen again and wrote several lines of formulas on the whiteboard:

"To make up for your current lack of firepower,

to prepare for the attack on the armed thugs' stronghold in a few days,

I will teach you how to make explosives tonight.

But before making explosives, we have to make detonators first.

As we all know,

detonators are the main charge of pyrotechnics such as detonators, percussion caps, and primers.

There are several requirements."

Qin Nuo pointed to a line of handwriting on the whiteboard:

"First, the detonation force must be strong.

The stronger the explosive force, the greater the work done by the detonated explosive.

Second, it must be sensitive enough to the external force to ensure accurate ignition when used.

Third, it must have good evacuation and pressure properties.

Fourth, good chemical stability.

At least the physical and chemical properties and explosive properties will not change easily when the ambient light and moisture change.

Fifth, it can be stored for a long time at room temperature. "

Just after he finished speaking,

Qin Nuo picked up the rag and wiped off the last line directly, and continued:

"There are many types of detonators, such as fulminate of mercury, lead nitride, lead trinitroresorcinol, etc.

And what we will make tonight is the most commonly used fulminate of mercury."

He walked to the experimental equipment,

picked out the curved-necked flask, mercury, nitric acid, and alcohol:

"You should have heard the teacher talk about the process of fulminate of mercury in chemistry class,

I don't need to repeat it, right?"

"..."

Not only Gao Wenwen was confused,

even Yan Shuihan, who was listening, showed a look of astonishment.

Which school on earth,

chemistry class will teach the production of detonators?

You graduated from the Middle East war zone, right?

Seeing that no one raised any objections,

Qin Nuo nodded with relief and motioned Lu Renjia to come over.

"Your task is to prepare the acid.

Dilute the nitric acid with water according to the standard of 60% concentration and the positive and negative difference not exceeding 1.5%."

The latter was pulled to the glass jar with the HNO₃ label,

bewilderedly took the latex gloves, thick rubber apron, pig nose gas mask,

with a bitter face, began to add materials and stir to prepare nitric acid.
