Let's start by analyzing the sun

In the aquaculture lake.

"Buzz~"

The engine sound kept ringing.

The wooden raft lightly cut through the water, stirring up waves on the wide lake.

Steward Zhang struck a pose of humbly seeking advice: "Technician Cheng, could there be a reason why the oil extraction rate has decreased by four percent?"

The other two crew members perked up their ears, waiting for Cheng Han's answer.

Cheng Han glanced at the lake, answering with a question: "Have you noticed that the green rice shrimp have become slightly slippery since winter began?"

Steward Zhang thought for a moment, then nodded and replied: "It seems to be the case! When the weather gets cold, you need to grab the green rice shrimp a little tighter, otherwise they easily slip away."

Cheng Han immediately explained: "This is because the green rice shrimp secrete a very thin layer of antifreeze oil on their body surface to resist the low temperature."

Steward Zhang suddenly understood: "I see."

The thin, tall crew member chimed in: "I thought it was just the water being too cold, but it turns out this is the reason."

Cheng Han got to the main point: "Secreting antifreeze oil will consume some of the nutrients in the green rice shrimp, especially a component called 'green oil paste'.

"This component happens to be one of the key ingredients of 'high-efficiency kinetic matter', which naturally leads to a decrease in the production of high-efficiency fuel."

Steward Zhang had an admiring look on his face: "Your knowledge is truly extensive."

The two crew members nodded repeatedly, looking deeply convinced.

Cheng Han sighed: "Half a month ago, the 'Aquaculture Research Institute' of the Dongli War Zone specifically sent a notice to various war zones.

"The notice clearly stated that as long as a special feed is put into the aquaculture lake to supplement the nutrition of the green rice shrimp, this problem can be avoided."

Steward Zhang immediately showed an embarrassed expression: "The higher-ups don't seem to have mentioned this."

The two crew members also looked subtle.

They naturally understood that this was definitely a dereliction of duty by some people in their war zone, who failed to pass on the information in a timely manner and failed to put in the feed as required.

Steward Zhang coughed lightly and asked: "Technician Cheng, is it still too late to put in the feed now?"

Cheng Han pondered for a moment and replied: "It's already winter, and the green rice shrimp's desire to eat has decreased a lot. It will take more than two months to see any effect."

Steward Zhang's lips moved, and he sighed: "What a pity."

The winter in this ocean world is not long, only about three months, and more than two months is equivalent to the winter being over.

The thin, tall crew member then remembered something: "No wonder the green rice shrimp seemed to be particularly able to eat some time ago, and the consumption of feed also increased a lot."

Another crew member began to apply what he had just learned: "They need to supplement nutrients to synthesize antifreeze oil in their bodies."

Cheng Han smiled and changed the topic: "The antifreeze oil of green rice shrimp has another wonderful use."

He paused, pointed to his face, and said: "In a while, when the temperature drops below freezing, many people's hands, feet, and faces will grow frostbite."

Steward Zhang's eyes lit up: "Do you mean that antifreeze oil can prevent frostbite?"

Cheng Han nodded: "Not only does it prevent frostbite, but it also has an excellent effect on treating frostbite. As long as you apply antifreeze oil, it can cure frostbite in at most three days."

Steward Zhang's eyes lit up even more.

Cheng Han smiled and simply explained: "As far as I know, the Dongli War Zone will not be able to perfect the process of refining antifreeze oil this year, and it would be a waste. If you can peel off the shrimp skin when catching green rice shrimp and try to extract the antifreeze oil, you can keep it for your own use or sell it."

The work in the aquaculture lake is quite hard, especially in winter when you have to come out and brave the cold wind, so doing this can be regarded as seeking some benefits for the workers.

Furthermore.

Peeling off the shrimp skin also makes it easier to refine high-efficiency fuel.

Steward Zhang and the crew members nodded repeatedly.

Cheng Han added: "By next year, the higher-ups will definitely not allow peeling off the shrimp skin privately, so the opportunity is only this year."

Steward Zhang and the crew members were extremely happy.

They had already heard that this was something tacitly approved by the higher-ups, and it was also a legitimate opportunity to earn extra money.

These people sincerely felt that this Technician Cheng was a very good person, and he spoke very nicely. He was simply a great talent.

Soon.

"Bang!"

There was a sound of collision.

The wooden raft leaned against the dock.

Two crew members immediately jumped onto the dock and skillfully began to tie the mooring ropes.

Steward Zhang pointed to the house next to the dock, and his tone became more eager: "Technician Cheng, how about going into the house to warm up by the fire?"

The smile on this guy's face was even more enthusiastic than seeing his own father.

This is not surprising.

Anyone who points out a way for him to make money would receive such treatment.

Cheng Han followed suit: "Okay!"

The reason why he gave benefits was to close the relationship with each other, and then to inquire about the intelligence of this war zone.

Steward Zhang nodded and bowed: "Please follow me."

Soon.

Cheng Han stepped into the house, which is the so-called "Lake Patrol Office".

This is also the "standard configuration" of each aquaculture lake.

The Lake Patrol Office is not big.

There are only three rooms, a main hall and a rest room.

The person in charge of night duty can rest in the rest room.

"Squeak!"

Steward Zhang pushed the door hard.

The air that rushed towards him was not much warmer than outside.

Cheng Han quickly glanced at the fireplace and asked calmly: "Isn't the Lake Patrol Office lit?"

As required, there are people on duty in each Lake Patrol Office at all times.

And in winter, in order to ensure that the stationed personnel can perform their duties, the room can be continuously heated.

Steward Zhang rubbed his hands again and sighed: "Don't mention it!"

He immediately explained: "This war zone does not pay much attention to the aquaculture lake, and the fuel quota provided is relatively low. We usually only light the fire at night."

Cheng Han sighed: "It's a bit harsh."

This was completely in line with his expectations.

This time, the Huiyang War Zone made a mistake by failing to feed the green rice shrimp according to the instructions, resulting in a decrease in fuel production, which is directly related to this attitude of "not paying attention".

Steward Zhang echoed: "Who says it isn't? I don't know how to get through the day when the weather gets colder."

He turned his head and ordered: "Xiao Li, go light the fireplace."

The reason for making an exception to light the fire at noon was obviously to entertain the "distinguished guest".

"Okay!"

The crew member immediately responded.

Cheng Han watched Steward Zhang pick up the kettle and asked the long-planned question: "By the way, does your war zone have any news recently?"

"Gurgle~ Gurgle~"

The sound of pouring water rang out.

Steward Zhang deftly poured a cup of water and offered it enthusiastically: "Technician Cheng, please have some tea!"

Then he recalled for a moment and replied: "If you want to talk about news, it's only about the war.

"The last time the White Squid tribe besieged our war zone, many people died, and all of us aquaculturists retreated to the fortress.

"Later, I heard that the Dongli War Zone fought a great victory, and even killed two Sea Gods. Only then did the White Squid tribe retreat."

The performance of the Huiyang War Zone in the war, like many war zones, can barely be considered mediocre.

If Cheng Han hadn't planned a strange strategy, I don't know how long the war would have lasted and how many more people would have died.

Cheng Han nodded lightly and asked more directly: "Doesn't your war zone's general have any achievements?"

His main goal this time was directed at this general.

The war reports submitted regularly by various war zones to the General's Hall only contain brief information, and it is impossible to understand the specific details.

It was precisely because of this that Cheng Han chose to travel incognito and quietly entered the Huiyang War Zone.

At this time.

When Steward Zhang heard the words "achievements", he actually sneered: "To be honest, our general has no performance on the battlefield, but his performance in the bedroom is extraordinarily powerful."

Cheng Han was a little confused.

What does "performance in the bedroom" mean?
