As the peak of the tide has passed, Zhuge Jin hurriedly let people go down the gillnet, and also told a few technical details:

For example, this time we are going to catch a fish at low tide, so the barb formed by the cracked bamboo should be facing north, which is also the direction of the upper reaches of the ditch.

Liu Bei and Sun Qian watched the excitement from the sidelines, and everyone was busy for a whole hour before they arranged the nets. Some pontoons are unstable, and they have to be re-fished up and weighted to ensure that they will not be washed away.

By the time this was done, it was already dark. But Zhuge Jin was not in a hurry to collect the net, and ordered people to light torches on the shore.

Liu Bei was a little impatient, and couldn't help asking, "Do you usually have to wait like this?" ”

"That's not necessary, isn't it an experiment now, you have to deal with accidents at any time and adjust in time. After the run-in is good, you can go down the net twice a day when the tide rises and falls. ”

Zhuge Jin explained while watching the sailors and guards operate.

As a result, a few sailors were lazy and misoperated, and he immediately reprimanded and rectified: "How many times have you said it!" To catch high tide fish, you need to light a torch upstream, and to catch a low tide fish, you need to light a torch downstream! What kind of fire are you lighting here? ”

The reprimanded sailors were quite ashamed, and hurriedly confessed: "I waited for the gentleman and the lord to stand here, and wanted to help illuminate the ......."

Liu Bei hurriedly waved his hand and signaled: "There is no need to be like this, since Mr. has an explanation, I will listen to Mr. for everything." Let's go a little further downstream. ”

Liu Bei demanded that Zhuge Jin's orders be fully implemented unconditionally, and the torches could not be moved, so it would be good for people to go over.

Seeing that Liu Bei didn't ask for a reason, Zhuge Jin was a little disappointed, just now he was actually ready to explain the scientific principle.

The group walked a hundred and ten steps downstream, but Zhuge Jin didn't calm down first, and took the initiative to ask: "The general is not curious, why don't I let torches be set up on the upstream shore?" ”

Liu Bei: "What Mr. is worried about must be reasonable, my generation doesn't understand, then listen to Mr., it will definitely not be wrong." If the gentleman thinks that this truth is simple, and we and other laymen can understand it, the gentleman will naturally say it. ”

Zhuge Jin couldn't help but be amused, and sighed: "Admire, admire, the general and gentleman are not instrumental, and the employment is not suspicious, and he is too Wei Wenhou." In fact, in the dark of night, fish also have phototaxis, similar to moths fighting fires. Light the torches downstream of the nets to lure more fish to migrate from there. ”

……

Between everyone chatting about popular science, bragging, and fart, they finally waited for the relative trough of the tide in the middle of the night.

Zhuge Jin saw that the empty bamboo pontoons on the bamboo slab were almost untenable, so he ordered the net to be raised.

A kind of sailor and fisherman in Liu Bei and Sun Qian's expectant gaze, carried countless large and small fish fresh bamboo pieces ashore one by one, and the process was very careful, lest the fish be lost.

For individual harvests, the whole net cannot be pulled, and the sailors have to jump into the water, take off the big fish hanging on the bamboo thorns first, and throw them into the fish protection.

Liu Bei looked at the amount of this harvest, and his expression changed from solemn to gratified, and finally to surprise.

"How can you get so much? And it's mostly sea bass! Even Matsue perch? ”

Liu Bei and Sun Qian are both knowledgeable, and just by looking at the harvests of the first few nets, they found that the proportion of sea bass is very high.

In the original text of "Romance of the Three Kingdoms", there is a bridge section of "Zuo Ci throwing a cup to play Cao Cao", saying that Cao Cao wants to eat Songjiang perch, so Zuo Ci can change out. Then Cao Cao said that this was an ordinary perch, and it was a trick that Zuo Ci had hidden in advance.

In the end, Zuo Ci refuted with "Everyone in the world knows that all perch in the world have two gills, but the Songjiang perch has four gills", and the fish he conjured up was indeed four gills, to prove that his illusion was powerful.

This is of course a novelist's words, but it can also be seen that in the Han Dynasty, saltwater perch was very precious. (Note: Fan Ye's Book of the Later Han Dynasty. Zuo Ci Biography also mentions that "Cao Cao's banquet guest said: "Today's high meeting, the delicacies are slightly prepared, and there are few Songjiang perch ears." But the Book of the Later Han Dynasty is an official history, and there is no detailed description of Zuo Ci's magic)

Nowadays, most of the fish washed by the Guangling tide are migrating from the river and sea, and naturally there are also a large number of sea bass.

Liu Bei and Sun Qian saw it in their eyes, and they couldn't help but show envy.

In particular, these are naturally grown, and they were rarely fished in the past, so they can grow to a large size. It is not comparable to the breeding industry of later generations, for the sake of profit efficiency, at most two catties are sold.

Liu Bei picked up a super sea bass weighing about seven or eight catties, observed it carefully, and was amazed:

"I've been eating fish for 30 years, and I've never seen anyone who can catch so many perch, fishermen in ordinary perch producing lands, and the harvest is only 20% of perch at most, Ziyu, how do you make more than half of it perch?"

Zhuge Jin didn't think about this question, and he couldn't answer it for a while.

In his experience, sea bass is not a rare species,

In the previous life, the vegetable market generally sold for ten yuan a catty, and in order to make more money, the proprietress often belittled the sea bass and promoted the bamboo shoot shell fish:

Sea bass is a fish that sinks to the bottom and dwells in the bottom, with a strong earthy smell, heavy metal pollution and easy enrichment, and greasy......

Thinking back to this, Zhuge Jin suddenly became enlightened, and then explained: "I know, the method of fishing for ordinary people is to use floating nets and shallow floating fish. My method today is to scrape the bottom of the river, and the perch likes to sink to the bottom, so naturally there will be more......"

He wanted to talk about other shortcomings in passing, but when he thought about the heavy metal pollution of a fart in the Han Dynasty, the greasy fish belly was not a shortcoming, and as for the earthy smell, it would be good to eat it.

And the perch does not have the characteristics of small spines, which is also a big advantage today, until the Song Dynasty, Fan Zhongyan also wrote "people come and go on the river, but love perch beauty".

Unexpectedly, with this method, not only can I catch many times as many times as many fish, but also cause the species I catch to become much more expensive.

After Sun Qian and Liu Bei understood, they could only sigh at the wonder of nature.

After some hard work, near midnight, the harvest was finally loaded and weighed.

Liu Bei was very curious about the final number, but he knew that Zhuge Jin's bet must have passed, and he knew that it was definitely more than 20,000 catties today.

"Lord, I have already weighed it out, I will get 34,000 catties of fish tonight, with an average of 1670 catties per scum, so that it is labor-saving to catch fish, as long as the tide rises and the tide recess and the net is collected on time."

Liu Beirao was mentally prepared, and when he heard the final number, he still clenched his fists and smashed the palm of his hand a few times:

"Hundreds of stone fish per day! 100 days is tens of thousands of stones! By the end of the winter, we can catch at least tens of thousands of stonefish! This gap in military rations has been completely filled! By the way, Ziyu seems to have said, this can catch two rounds of the tide every day, right? Wouldn't it have to be multiplied by two? ”

Zhuge Jin poured cold water on the side at the right time: "It can't be counted like this, today is the biggest tide day of the year, and the harvest is naturally the best of the year, which is far from being reached in normal times." ”

Liu Bei still didn't give up, and thought again: "Then can you set up and expand fishing everywhere along the river?" ”

Zhuge Jin: "There are many interceptions, and the next few will not be so big." Moreover, this is the natural characteristics of taking advantage of the confluence gap between Hangou and the Yangtze River and the Huai River.

At most, we can only get one set on Yunchang's side and Huaiyin County, so that the total output can be doubled, but that's all, and we have to think of another way in the future. ”

Liu Bei felt quite sorry at this time, it seems that farming still has to be planted, and fishing cannot become the main source of food after all, so he thinks too much.

But it could be twice as much as it is today, which is something he didn't dare to think about before.

And Zhuge Jin obviously didn't take out all the fishery techniques he knew.

First, he only has some ideas, and he still needs to practice and explore slowly.

Second, the bamboo sunken-bottom gillnet is one of the simplest and has the highest requirements for the geographical environment. Only Guangling and Huaiyin can maximize their benefits.

Even if other princes learn, they don't have the geographical environment to play for the time being.

Other, more complex technologies are more versatile.

Zhuge Jin felt that those jobs could be handed over to the second brother to summarize and explore after a while, and he only needed to get through the difficulties in front of him.

Anyway, the two bets he played with Liu Bei were overfulfilled.

……

Because he was too late, Liu Bei didn't leave him for supper that night, and they went back to their homes to rest after finishing work.

But early the next morning, Liu Bei was very excited and took the initiative to come to him to discuss matters, and he also had people steam fat sea bass with green onions, ginger and rice wine, as well as other wine and meat.

Liu Bei should have been thinking about how to take advantage of these good news all night, so as soon as they met, he asked: "Sir, now that our army has a shortage of military food, it can be regarded as basically solved." However, I think we still need to focus on promoting the previous deployment of persuading farmers to do winter mustard - although it is not bad for those few mouthfuls of green vegetables, don't be kind and small.

A while ago, I was pondering that Gongyou's side lacked some 'miraculous traces' to convince the people that the method we promoted was absolutely effective. Yesterday's drift gillnet fishing was so effective, didn't this 'miraculous' be sent to the door?

In the past few days, we have caught a few more times with great fanfare, and the details can be hidden, and when the final harvest is made, the people are allowed to watch from afar, and we will sell sea bass to the people with great fanfare. In this way, the local rich must believe that we have a wonderful way to catch a lot of sea bass, and they will definitely trust us more in the other methods of persuading farmers, right? ”

When Zhuge Jin was approached, he hadn't woken up too much, and when he heard this plan, it was probably no problem, so he casually said "ah, yes, yes, yes".

Liu Bei couldn't help but be greatly excited when he saw that his idea could be passed at one time by a divine strategist like Zhuge Jin, and he felt that he seemed to be better than before.

He hurriedly threw out another plan: "Now that the military rations have been basically settled and the war has been settled, the most urgent thing for our army in the next step is to negotiate with Lu Bu, try to achieve reconciliation, and redeem the families of the soldiers." Can Ziyu teach me a wonderful way to do this? ”

Originally, Liu Bei couldn't take care of this, because the other two major events, each of which was more urgent than redeeming the family.

Now that I'm free, this matter must be solved immediately.

Otherwise, dozens of soldiers flee every day, and they want to go back to their hometowns to find their relatives, and they can't bear it over time.

Zhuge Jin was speechless for a while: Why did you catch me as a strategist? Did I say I understand diplomacy? Didn't you?
