I have a sea in ancient times

Chapter 182 Fluorine and Ammonia, Stupidly Unsure
After treating Xiaobai's wound, Lu Hai followed the instructions of the owner of the hardware store, first opened the acetylene cylinder, ignited it, and adjusted it to a neutral flame.

In gas welding, carbonization flame, neutral flame and oxidizing flame are commonly used, and neutral flame is used for welding air-conditioning copper pipes, and the temperature is about 3000~3500 °C.

After adjusting.

Lu Hai took out the welding rod and operated it carefully. Since the copper pipe is not very large, Lu Hai finished welding quickly. As for whether it is welded well.

We have to wait until the freon is added to find out. Speaking of freon, it is really interesting.

I have seen an entire province where one thing is collectively staggered. In this province where Luhai is located, almost all Freon is called ammonia addition.

Because of this, Lu Hai made a special search on the Internet and came up with a convincing answer, because the people in his province did not speak standard Mandarin.

The front and back nasal sounds are not clear, which leads to the indistinguishability of Freon's Ang and ammonia. In the end, it was misrepresented, and the addition of fluoride became ammonia addition.

When you come to this province in the future, when you hear about the addition of ammonia to air conditioners, you understand that it is better to add Freon.

After Lu Hai finished adding Freon, he unscrewed the valve and wiped some soapy water on the welding place. It seemed that there was no bubbles. It seemed that his welding skills were still good.

Maybe, you can pick a time to take the exam as a junior welder, and give yourself another possibility in your life.

Lu Hai put a protective cover on the copper pipe, started the diesel generator set, and turned on the air conditioner. Sure enough, a cool wind blew over.

Now, finally, instead of lying in the car and taking a nap, you can lie in the container bedroom and take a good nap.

After doing these things.

Lu Hai reorganized the net rope fence in the safety zone, and opened up the space a little, expanding the scope of the safety zone.

As for the hole that the little wild boar finally dug, due to the expansion of the safety zone of land and sea, the location of the hole is still in the safe area.

After about time.

Lu Hai called Monday and asked her to shovel the oysters into the carriage first. Thanks to many contacts, Monday was not as scary as before.

The efficiency of shoveling oysters is also much higher, and I tried to touch or touch them secretly several times, as if touching a giant beast.

During the time she was shoveling oysters, Lu Hai went to the shore to increase her exploration points, because the system has become a second form.

In the past, items had to be photographed with a mobile phone to be identified, but now as long as Lu Hai touches the item, he can directly identify it.

It didn't take a while.

Luhai has identified more than 100 kinds of marine life on the shore, including sea cockroaches, sea oyster snails, rattle snails, sandworms, sea centipedes, coconut snails, sea anemones, starfish, sea urchins and so on.

The current exploration points are 209 points.

1 point can be exchanged for 100 mu, that is to say, these points can be exchanged for at least [-] mu of exploration space.
Lu Hai planned to wait for Yunlan Hotel, and after sending the money, he would upgrade the space level to level 8 first, then use the exploration points to buy the exploration space, upgrade the space level to level 10, and then unlock the hardworking gift package.

Lu Hai threw a set of wader pants to Monday, and asked her to wear thicker gloves. Since she is very good at imitating now, Lu Hai has done it once, and she can almost imitate it.

Followed by.

Lu Hai asked her to board the boat together. This kind of big fishing boat is different from the fishing boat in the sea catching video. It is very troublesome to operate by one person, and at least two people are needed to cooperate.

After land and sea ship.

After checking the equipment on the disembarkation ship, there was no problem. This time he did not drive very fast because of the experience of hitting the rocks last time.

Lu Hai was a lot more careful this time, and went to the place where the fishing boat was damaged last time, and dropped a buoy down. The next time he passes by here, he will know to avoid it with this buoy.

Next.

Lu Hai drove the boat to the position where the ground cage was placed, and then used the cage lifter to pull up the ground cage.

After the first cage is up.

Just as Lu Hai expected, a lot of seafood had stinked and died.

The ground cage was confiscated for two days. Due to the large amount of catch, these marine creatures fought in groups in this narrow space. Many sea fish were injured by crabs, and the crabs were also cut off.

At least half of the mackerel was stinking, and the whole gills were white, and the situation of the balang fish was similar.

But these are not the worst.

The worst thing is that those sea snakes who ran to the ground cage to steal food almost all died.

Although sea snakes live in the sea, they breathe with their lungs just like sea turtles, dolphins, and whales. Once they enter the ground cage, they cannot escape. The only thing waiting for them is to "drown".

In the real world, many sea turtles, dolphins, and whales die because they are entangled in fishing nets and unable to surface to breathe.

Lu Hairang used pliers on Monday and threw all the dead sea snakes back into the sea. This kind of thing really cannot be grasped by hand.

There might be some fraudulent corpses, and if he was bitten, he might still be able to save himself, but this primitive man must have no solution without serum.

When handling such poisonous things, even if you are facing a corpse, you must be cautious.

The job of sorting out seafood.

Lu and Hai will leave it to Monday. For those dead seafood and crabs with severed limbs, Lu and Hai will let Monday throw them back into the sea.

Fortunately, the grouper's vitality is relatively tenacious, and they are originally top-notch carnivorous fish, except for encountering such ruthless characters as sharks.

The grouper is also considered to be the dominant one in the offshore area, so most of them survived. It may be because the grouper has spawned recently, and the grouper caught in the ground cage is a bit too much.

And there are quite a few groupers that lay eggs directly in the ground cage, as if using the ground cage as a breeding base, and there is a gentian grouper among them.

However, even if this grouper lays eggs, it is not very useful, because they belong to a species that is 100% yin and yang.

A hundred gentian groupers may not have a single male fish. The gentian grouper must first be a female fish for ten years, and it is possible to become a male fish after the tenth year.

Therefore, many fish eggs cannot be fertilized at all, and can only be reduced to food for other animals, which is why wild gentian grouper is scarce.

However, some farmers have mastered the technology of controlling the degeneration of grouper gentian, which greatly increases the fertilization rate.

It is said that the breeder who first invented the grouper sex change operation earned tens of millions of dollars a year just by selling grouper eggs in the first few years.

Almost all the grouper farmers on Xiaqi Island went to him to buy fish eggs.

After collecting the first cage.

Although more than half of the seafood was disposed of, due to the fishing season, the fish was still good, and Monday became more and more proficient.

Put the corresponding seafood in the same bucket if you can prepare it. Lu Hai plans to go back this time, but because of some seafood photos, they are posted on these buckets.

In this way, the seafood can be clearly classified through photos on Monday.

With her help.

Lu Hai's efficiency in collecting the cages is obviously much higher. It used to take three to four hours to collect more than 40 cages. Now it has changed to a big fishing boat, plus Monday's help.

One hour.

Just get the more than 40 ground cages.
