My Doomsday Shelter Unlimited Upgrades

Outsiders may not know it, but Jiang Yanbing knows the situation best in her heart. She has never been in a relationship until now because of her strict family education and busy study, and most boys only treat her Dare to see the point.

Because there are too many people chasing after her, she has developed a cold feeling of rejecting thousands of people since junior high school. She can't learn the charm of the teachers on the poster. She also heard that However, boys like girls who burn a little bit, is it true?

Jiang Yanbing withdrew her thoughts, knowing that the more she thought about it, the more outrageous she became. She hadn't even considered whether to stay here, so why did she start thinking about it again.

Jiang Yanbing picked up the police chief and said a few words to himself:

"If you want to blame, you have to blame that person named Chen Yang. You insisted that you saved me, and you only gave me a day to think about it. What's wrong with me? You want me to go so much? Don't you think so!"

"Meow meow!"

Chapter 46 Layout of the Trenches

"Ah cut! Ah cut!"

Chen Yang sneezed twice.

"It's weird, how can someone scold me here?"

After leaving the house, Chen Yang went straight to the trench outside the shelter, and was standing beside the trench thinking about starting the fire.

Before that, he went to the field to take a look at the growth of potatoes.

Calculated according to the time, it has been almost three days now, and the perfect potato seed has grown relatively large green leaves at this time, and it looks like it can be harvested from the outside.

Although potatoes grow in the ground, their signs of maturity are relatively obvious. Once the stems and leaves of the plants on the potato seedlings turn from green to yellow, and gradually become withered and yellow, it proves that the potatoes are ripe.

Just now he saw that the stems and leaves of the perfect quality potato were still green, maybe it had just matured. To be on the safe side, Chen Yang decided to wait a little longer to ensure that the potatoes were ripe before digging them out.

Except for the perfect quality potato seedlings, all other potatoes are still in the growth stage. Ordinary potato seeds can hardly even see the signs of growth. There are only a little green shoots, and they are still a thousand miles away from maturity. distance.

If the potato fruits produced by perfect potatoes are also of perfect quality, then he will get rid of all other potato stalks without hesitation, and only plant crops of perfect quality in the future, and harvest them in a few days.

As for arranging Jiang Yanbing alone in the room, Chen Yang is quite at ease. With the police chief watching her there, at least there will be no electric shock or sabotage. This kind of stupid thing, let her think about her proposal in the refuge, which can be regarded as giving her a cooling-off period.

After watching the potatoes, Chen Yang did not plan to return to the shelter for the time being, so he came to the trench and began to study the ignition of the trench.

After having alcohol, according to his own idea, Chen Yang filled the trench with charcoal and weeds, and at the same time made a simple alcohol lamp out of glass, and plugged the upper part of the alcohol lamp with a cotton wick.

Cotton has strong water absorption and will automatically absorb the alcohol in the container. Since the ignition point of cotton is higher than that of alcohol, when the wick soaked in alcohol is ignited, it is the alcohol in the cotton that burns first, not the cotton itself. It is also one of the important reasons why alcohol lamps do not burn rope like candles.

Chen Yang added medical alcohol to the alcohol lamp. The concentration of medical alcohol is 75%, but the alcohol added to the general alcohol lamp needs to be 95%. The lamps would often burn out, but now there was no such condition, and Chen Yang had no choice but to act as a living doctor, so he could light it first before talking.

Preventing the alcohol lamp from being in the trench, Chen Yang pulled out a thin lead wire of tens of centimeters, connected the lead wire to the wick of the alcohol lamp, and lit the lead wire from a distance.

The lead wire is relatively thin, and the burning speed is relatively fast. Within ten seconds, the spark is connected to the wick of the alcohol lamp, prompting the alcohol lamp to start burning.

What Chen Yang had been worried about happened at this moment.

The flame intensity of the alcohol lamp is stronger than that of a lighter. In addition, due to the lack of alcohol purity, the flame intensity of the alcohol lamp is strong and sometimes weak. It takes a lot of money to ignite the weeds and sawdust above the alcohol lamp. Time, it is estimated that by the time the flames spread to the entire trench, the tortoise would have fallen behind the rabbit seven or eight times, and the fire was still in danger of being blown out at any time, it would not feel like a flame fortress.

Chen Yang was at a loss. It would be great if the system could detect his intentions, so that he could use materials or survival points to upgrade. The system can always produce some non-scientific things, and a mere flame trench will definitely not be a problem.

The current predicament is that the system did not recognize that what he made was a flame trench. Those who didn't know it thought it was an O-shaped pig trough. Perhaps the entire trench had to be set on fire before the system could recognize his intentions.

But that's the problem. It's not easy to light one place, so why talk about lighting all the trenches?Alcohol is limited in quantity and cannot be wasted like this.

When Chen Yang was at a loss, the fire in the trench was also spreading quietly, but the speed of spreading was extremely slow, and there were signs of being blown out by the breeze immediately.

At this moment, the system popped up a prompt.

[Simple Flame Trenches]:

The trenches lit with alcohol lamps are extremely inefficient, and they have a slight defensive effect after all the trenches are lit.

Upgrade Direction 200: Change the ignition method, use the aerosol electric method to ignite the trenches, greatly increase the ignition efficiency and reduce fuel consumption, [-] survival points are required.

Upgrade Direction 150: Adding a blower system, which can change the direction of the flame burning, requires [-] survival points.

System comment: Huo Huo Huo Huo Huo Huo Huo Huo Huo Huo, the routine moves of Huojiaquan are flexible!

"Hey, it's better to come early than coincidentally."

Chen Yang's favorability for the system has increased again. To be honest, he can't tell that he is a flame trench, but the system has recognized it. This is more or less indebted to him. .

Upgrade direction [-] Chen Yang understood it immediately. After adding the blower system, he can control the direction of the flame burning, that is, indirectly control the direction of the thick smoke emitted by the flame burning.

In fact, Chen Yang had thought of this a long time ago, which is also the main reason why he didn't dig trenches very close to the refuge. One is to prevent the internal high temperature, and the second is to prevent the invasion of burning smoke.

When a fire occurs, it is often not the flame itself that is fatal, but the smoke produced by the flame.

The smoke contains a lot of toxic components, such as carbon monoxide, hydrogen cyanide, sulfur dioxide, etc., no matter which one is taken out, it is harmful to the human body. People trapped in the building are generally not burned to death by the flames first, but blown to the face The coming strong smoke choked to death, or was smoked into a coma.

The blower system is a good thing. It must be upgraded. Although there is a certain distance between the trench and the shelter, everything must be considered in case. He currently has more than 700 survival points, and he should not be stingy with the consumption. .

But as soon as the upgrade direction was reached, Chen Yang couldn't quite understand it. What is the aerosol electric posture?He had never heard of it.

Seeing is worse than trying, Chen Yang decided to directly upgrade to find out.

Iron blocks, alloys, rubber... After some basic materials are placed, the survival points required to upgrade direction 350 and 200 are reduced from [-] to [-].

To Chen Yang's surprise, the materials needed for the upgrade also included many alloys and iron-chromium-aluminum metals. I really don't know what the upgrade is.

After confirming that he could no longer save survival points, Chen Yang clicked on upgrade.

[Aerosol flame trench (excellent)]:

The ignition is carried out by aerosol electric method, and gasoline/diesel/alcohol can be used as fuel.

Upgrade Direction 1500: Change the flame burning method and ignition method, the required survival points are [-] survival points.

Upgrade Direction 1000: Join the fire control and temperature control system, which can control the size and temperature of the flame, and requires [-] survival points.

Additional attributes: fire +100%

System Comments: Only for barbecues!

[Please confirm the location of the ignition console! 】

"Another excellent attribute!"

Although the probability of producing items with excellent attributes is not low, Chen Yang is still a little excited every time a high-quality item really appears.

This time the additional attribute is fire power +100%. Chen Yang thought about it for a moment. This entry sounds good, but it is not so perfect when he thinks about it carefully.

If the fire itself is big enough, then add 100% of the fire on top of it, and the situation is likely to get out of his control and eventually lead to a raging fire.

Of course, this is only on the premise that the assumption is true. If the fire is not big, then this entry is very useful.
