Researchers aren't there yet, though

However, Zhang Feng had already redeemed a laboratory construction drawing from the system, and asked Professor Wang to introduce an experienced engineering team to immediately renovate the laboratory.

As for the various equipment in the laboratory, he didn't need to worry about it at all, and when the researchers arrived, he could exchange what equipment he needed from the system.

The matter in the laboratory came to an end for the time being, and Zhang Feng's heart also breathed a sigh of relief.

……

The next day

Zhang Feng was idle again

Recently, tourism in the village has also entered the off-season, and with the arrival of winter, there are fewer and fewer tourists from other places, and I only hope that there will be more tourists on weekends and New Year's Day.

After breakfast in the morning, Zhang Feng walked to the entrance of the village, first went to his own eel farm to see, Uncle Lao Yu managed in an orderly manner, so that he was very satisfied, although it does not earn much a year, but it is also tens of millions, nearly 100 million, so Zhang Feng is ready to continue to operate.

After bidding farewell to Uncle Yu and the farm, Zhang Feng came to the field at the entrance of the village again, and saw that everyone was busy in the field, some were picking vegetables, some were watering and fertilizing vegetables, removing weeds, etc., everyone was very happy.

At this time, in the rotten fields at the edge of the field, a group of young people were fishing in the paddy fields, and there were many tourists watching on the side.

"It's these guys again!" Seeing that they were all generous Ah Hong, and there were a few fat people, Zhang Feng couldn't help laughing, so he prepared to go over to see the excitement.

Five or six guys, dressed in waterproof suits, were catching fish in the rotten fields with a dustpan and a bucket, but unfortunately they heard the roar, but they did not see the harvest, and the buckets were empty.

"Ah Hong, what are you doing, why haven't you caught a single fish?" Zhang Feng walked over and asked with a smile.

"Brother Crazy is here, we don't know, it's really strange today, I haven't seen a single fish!"

"Yes, Brother Feng, we caught so many fish last year, but today we didn't have a day, and we didn't even see a loach eel!"

Ah Hong and the others all smiled bitterly and explained to Zhang Feng.

Hearing the words of a few guys, Zhang Feng was also very surprised, how could this be? Last year, everyone caught no less than one here, but this year, why didn't there be any of them?

"Won't they all run away?" Dafang guessed with some confusion.

"No way, this paddy field is still flooded with this water, where can they escape, I see if they are polluted by pesticides, they are all dead!" Ah Hong shook his head, and also said his guess.

Hearing Ah Hong's words, Zhang Feng still shook his head: "Now our village uses non-toxic pesticides, how can it be possible to poison the fish to death, I will see if there are natural enemies in the water." ”

"Yes, is there a black fish in this??" Hearing Zhang Feng's words, everyone's eyes suddenly lit up, and they felt that this was the most likely.

"It's a pity that we don't know where this black fish is!" This rotten field is about an acre, and the situation in the water is complicated, as long as the black fish drill into the bottom, who can find them, so Ah Hong spread his hands and said helplessly.

"Why don't we put the water in the field?" suddenly Fat Dun proposed to everyone.

"Okay!" everyone clapped their hands and decided to do just that!

Ah Hong borrowed a hoe from the side, and Bang Bang dug a big hole in the field in three or two clicks, and the water in the paddy field flowed into the ditch with a bang.

About ten minutes later, the water in the field finally bottomed out, and only then did I see a few small fish struggling and jumping in the dry Tian Zong, one of which was more than a pound of big fish, and not only Zhang Feng and a few people saw here, but even the tourists were a little dumbfounded.

I don't know what it is, but if all the fish and shrimp in such a large paddy field are eaten cleanly, will there be any water monsters lurking in the mud, everyone feels that this scene is very weird.

"Wow, there's a fish, it's such a big black fish!!" At this moment, Ah Hong suddenly exclaimed,

Everyone looked in the direction of his finger, and sure enough, a big black fish was burrowing into the dirt, and half of its body was already in the dirt.

Just now, everyone didn't find it for the first time, and that was because the color of the black fish was almost the same as the color of the mud in the rotten field, so everyone didn't immediately notice its existence.

"Hurry up and catch it!" Fat Dun immediately exclaimed excitedly.

A few guys used their strength to eat, like a 100-meter sprint, and ran quickly towards the black fish, although the field was full of mud, it was difficult to move an inch, but everyone still ran very fast, and they came to the black fish in more than ten seconds.

"Quick! Grab him by the tail!"

"Be careful, don't get fanned by its tail!"

Several guys have been catching fish in the fields since they were children, so they are extremely experienced, and several people worked together to quickly catch a large black fish half a meter long.

"It's so big, this black fish is estimated to be one or two pounds!"

"Ah, this black fish looks so fierce!"

"Of course, the black fish is a carnivorous fish, of course it is fierce!"

When the tourists saw the black fish being caught, they immediately became excited, and even wanted to go down to the field themselves to catch a few big fish.

It's a pity that there is only one that can be seen in the field, and the other blackfish are probably hidden in the mud, and it will definitely not be so easy to find out.

Because the black fish has strong adaptability to the changes of environmental factors in the water body, especially to hypoxia, water temperature and poor water quality.

When a body of water is starved of oxygen, it can expose its head to the surface of the water. Posterior lateral flattening. The head is long, slightly flattened anteriorly, slightly raised posteriorly. Oxygen from the air is breathed directly with the help of a suprabranchial apparatus consisting of a piece of bone extending from the upper gill bone on the dorsal surface of the first branchial arch and a lingual jaw extending within the gill cavity. Therefore, it can survive for quite a long time even in humid areas with little and no water.

In winter, when the water temperature is close to 0 °C, the black fish will lie dormant in the bottom mud and stop eating, so in the soil of the paddy field, it is estimated that there are still a lot of black fish, because if there is only a black fish, it is impossible to eat the fish and shrimp in the paddy field cleanly, and there must be a lot of fish that have slipped through the net in the soil.

However, the black fish in the soil are well hidden, and everyone can't find any clues about them at all, so they can only grope around in the paddy fields, but unfortunately after digging the mud for a long time, the scales of the black fish are not seen.

"Let me come!" Zhang Feng couldn't stand it anymore, and decided to use the system to cheat, and the system scanned the paddy field, and the black fish lurking in the soil suddenly had nothing to hide, and all of them showed their original shapes.

Zhang Feng stroked his trousers, took off his shoes and socks and walked like walking in the water.

"Brother Wo Groove Feng, you're not cold!"

"Yes, Brother Feng, or I'll give you the waterproof suit!"

"No, I'm fine!"

Zhang Feng waved his hand and declined everyone's kindness, after more than a year of non-stop practice of gymnastics, at this time his body has exceeded ordinary people too much, there is no problem wearing T-shirts in winter, just to not look different, his clothes are the same as everyone.
