Chapter 164

Not to mention the firing speed of the M1 automatic rifle, the subsequent type 80 general machine gun alone has a firing speed of about 700 rounds per minute.

The price of a bullet is 2 points, and it costs 1400 survival points in a minute. Who can stand it!

"If you want to build my great wall of steel, you must ensure that there is enough ammunition, otherwise everything is empty talk."

"Smokeless powder must be taken down"

Su Mo has taken 99 steps to build guns and assemble ammunition, but he is only the last step. If he can't get through, he must go hard, and if he can't push, he must push hard.

Adhering to the tradition of the older generation of Chinese scientists, Su Mo has full confidence in adhering to this.

But before that

"Airdrop, airdrop, when can it arrive!"

Out of the basement door, looking at the cloudless sky, a quiet, how did not see the shadow of a drop.

The award of the world's first person made Su Mo itch. He couldn't wait to see what kind of good things the game would put in.

It seemed to hear the murmur of Su Mo, and the game panel bounced out by itself, and a prompt tone sounded cordially.

[record]: the current airdrop arrival time remains 02:13:45

"Hey, will it take two hours to arrive?"

After reviewing the tips of the game and confirming that the time was decreasing, Su Mo temporarily put his heart down and began to study how to purchase cotton.

The 65 survival point can get 500g cotton, and through a series of manufacturing, it can produce about 350g of smokeless powder.

After the train is loaded into the bullet, other labor and material costs are excluded according to the survival cost. A bullet is worth 0.3 survival.

Based on the firing speed of the 80 type general machine gun, the cost of one minute is 260 survival points!

"Expensive! It's still too expensive! In the future, there must be a suitable cotton base to greatly reduce my losses, otherwise, if it goes on like this, there will be no need to think about the shells behind. One shot at a time is thousands of survival points."

If you are not on the home court of the earth, there is no material accumulation. Even if you want to search, you can only go to the ruins.

A thing that can be easily solved on earth, when it comes to waste soil, it is necessary to establish a series of production lines from scratch.

"It is also a population problem. The more people there are, the more resources can be collected. At the same time, it can also speed up the development of shelters and provide stronger disaster resistance."

Reluctantly, I found the root of the problem. Looking at Oreo, who was still playing with sparks in the empty garage, Su Mo could only open the trading channel and try to search for cotton.

Like wood, cotton is also a scarce material for the winter, with a high selling price.

For the time being, we can't figure out which kind of cotton can make firecotton. Su Mo can only use 65 survival points to make a kilo first, and choose according to the cotton in his hand.

This time, the goal is much clearer.

At the cost of 10 big cakes and 10 disaster points, we finally got back 20 kilograms of cotton.

These cotton can produce about 3000 rounds of bullets after removing the loss, which is enough for the early shelters for the time being, so there is no need to worry about ammunition.

Seeing that the time of airdrop was slowly approaching, Su Mo didn't waste time with the goal. He went to the oil well first to replace toluene with ethylene.

Manufacturing nitric acid and sulfuric acid is already familiar, so it's natural to say nothing.

It didn't take much effort. Sumo finished the manufacture of the kapok in an hour. Carefully take the wet kapok back to the storage space and put it away. Looking at the time, sumo simply continued to prepare picric acid.

The benefits of continuous production of tools in the past two days are obvious. When manufacturing picric acid, sumo can feel that his speed is significantly accelerated.

In particular, while waiting for the reaction, we can spare energy for subsequent preparation, which is enough to show that the production level has been fully improved.

Sumo doesn't intend to leave all the saltpeter. Except for preparing sulfuric acid and nitric acid to catalyze the cotton wool, all the others are used to prepare picric acid to prepare for the capture of the Kobold castle.

The time consumed by handmade is the same as when driving. When the system prompts that the airdrop is coming, Su Mo stands up, walks out of the garage door and waits quietly.

As soon as the time came, the airdrop belonging to the world's first person arrived as promised.

The delivery method is not to drop the box when Su Mo imagined the plane carrying the box passing through the underground shelter, but to adopt a more "advanced" delivery method, which Su Mo has seen several times.

Golden light projection.

A whole piece of brilliant light flashed across the sky. When passing the underground shelter, it stopped, and a box about one square meter appeared in sumo's field of vision.

It seemed that Su Mo's identity was checked. Jin Guangyun shook and scattered a small cloud, dragging the box down.

Until the light cloud was about five meters away from the ground, it stopped in the same way as the ruins disappeared, turning into light spots and crashing into pieces.

Without buoyancy, the box fell down and just landed in front of Su mo.

"This way is really a bit like magnetic levitation, but it is obviously much higher than the practical theory put forward by human beings!"

Seeing the golden light on his head leave, Su Mo didn't wait and hurried to the falling airdrop box.

The dropped box looks smaller, and it doesn't look like it can store precious items.

But after seeing the magical card technology, Su Mo did not despise it at all. He carefully picked up the box marked with airdrop and walked into the garage.

Put down the storehouse door and the stone door in turn, and walked into his own small world. Only then did Su Mo stop and start unpacking.

Large pieces of boxes smeared with No1 printing are extremely beautiful, and under the light, they also reflect various luxurious colors.

Gently untie the iron buckle on the box. As sumo opened, the airdrop box burst into a light like the silver box, and the three items automatically flew out, shaking in front of sumo.

A black card, a red brocade bag, and a prop like a compass.

"It's card technology!"

Sweep the box aside, scoop up three items and sit on the soft cloth sofa. Su Mo began to look at them one by one.

This punch, the first black card made sumore's not light!

After discharging the attributes of the game panel, sumo began to observe carefully.

[small single arm excavator (excellent)]

[description]: a small diesel backhoe excavator produced by a heavy machine has working methods such as ditch end excavation, ditch side excavation, straight-line excavation, curve excavation, maintaining a certain angle excavation, ultra deep ditch excavation and ditch slope excavation.

[machine weight]: 13500kg

[bucket capacity]: 0.50-0.65 (M3)

[rated power kw]: 72.7/2200

[walking speed (high / low) km/h]: 5.5/3.5

[climbing capacity]: 70%/35 °

[limit]: currently the card is locked, and the countdown to locking is 78 hours

[usage]: when used in the open space, you can summon the card carrier to come. Once it comes, it cannot be recycled. Please choose carefully

"Good guy, is the reward of the world's first person so awesome?"

Looking at the introduction of the card, Su Mo rubbed his eyes and was surprised to find that the words had not changed and that there was no restriction that they could only be used once!

Excavators reflect the mechanization level of a country, the progress of a machinery industry, and the reduction of human labor.

With a huge bucket, the productivity increase brought by the excavator alone is enough to support more than ten people working at the same time.

Especially in some buildings, it has a unique bonus.

"Fortunately, I chose live broadcast for the first time because of Huang Biao, otherwise I missed this airdrop."

Misfortune brings happiness and misfortune. Through the reward of the world's first person, Su Mo instantly decided:

The second time must be broadcast live!

Put the card of the excavator into the storage space, pick up the second brocade bag, and Su Mo starts to check it.

[bonus points bag (ranking first, reward, binding)]

[description]: open to directly obtain 1000 disaster points

Ordinary introduction can't hide the shock brought by four digits. Without hesitation, Su Mo directly chose to open the brocade bag and 1000 points were instantly paid.

When the last thing looked like a compass, Su Mo's state of mind had calmed down, and there was no sign of anxiety at all.

With excavators and bonus points, this air drop reward can be said to greatly improve the mechanical level of the shelter.

As for the compass, it is not so important whether it is good or bad.

[finger pin (rare)]

[description]: press the button above the finger pin, meditate on the image of the thing you are looking for, and then blur the position

[limitations]: the accuracy of the position will deepen with the degree of fetter with the user (common fetters: blood, friends, pets...)

[limit]: 3/3 times of use
