I'm a fisherman, so it's reasonable to get rich by fishing, right?

"No wonder the system says that there are only some species in this world, and that's what it said?"

Rong Bing was shocked and a little surprised in his heart! If he fished these fish back to the earth, would he frighten many people?

"Hey, hey......"

Rong Bing hung up the bait with a strange smile and threw it directly with a 10.6-meter fishing rod.

With such a long fishing rod, throwing bait also requires skill, and Rong Bing uses a throwing technique called "Invincible Hot Wheels".

The so-called invincible Hot Wheels is to put the fishing rod flat on the turret first, hang the bait on the hook, grasp the wireless two feet above the lead skin, and throw the bait wheel in a circle with the technique of throwing the nunchuck in the air.

The location of Rong Bing's throw this time was in the nest of a group of Chinese sturgeons, and as soon as the bait was in place, it caused a group of sturgeon to scramble.

As soon as Rong Bing lifted the fishing rod, he felt a sinking in his hand, and he flew ......

After fighting with the two sturgeons for about ten minutes, Rong Bing violently pulled the fish out of the water and pulled it back in his direction.

"Wang...... Little master, do you need Wangcai's help?"

Seeing Wangcai who was on the fish, he immediately ran to Rong Bing to sell cuteness.

"Go, go, this fish can't be bitten, I can get it myself.

Rong Bing drove away Wangcai, and with another fishing rod, two Chinese sturgeons of more than ten catties were suddenly lifted to the shore.

"Hey! The combat rod produced by this system is really awesome, twenty or thirty catties fly directly!" Rong Bing touched the fishing rod in his hand and smiled happily.

The two Chinese sturgeons were included in the super fish protection, and Rong Bing continued to hang the bait and throw it.

"Look at my invincible Hot Wheels......"

Rong Bing threw the fishing line into a circle and threw it directly towards the fish nest.

"I'll go, rob the drift......"

Rong Bing saw that the fish drift hadn't even stood up, so he was dragged and ran away, and immediately raised the pole.

"Are all the fish in this world so hungry?" Rong Bing was curious as he set up his fishing rod.

In the next two hours, Rong Bing actually caught hundreds of Chinese sturgeons.

For this wild Chinese sturgeon, if you catch it on the earth, you will be directly pulled to drink tea, but no one in this world seems to care?

Just now, several batches of people who passed by saw him put the Chinese sturgeon into the fish protection, and I didn't see any overreaction from them!

"Hehe, bringing these fish back into the Yangtze River can be regarded as contributing to the earth's biosphere, right?"

Rong Bing smiled proudly, but was entangled by the system's words.

"The fish caught by the host in this world, in exchange for points or money, are very high, are you sure the host wants to take them back and release them?"

"No, don't I just want to do something good, why bother?" Rong Bing said with a bitter face.

"The host can collect the eggs of the fish in this world and hatch them. The system said.

"Fish eggs, this can be had!" Rong Bing was excited again and simply stopped fishing.

He turned on the intermediate fluoroscopy technique and began to search for the eggs of Chinese sturgeon and white dolphin in the water.

However, he searched for several minutes, but he did not find any eggs for both fish.

Rong Bing asked the system with some frustration: "System, how can we find the eggs of these two kinds of fish?" "

The system mall has this information for sale, and the host needs to buy it directly." The system replied.

"Buy, buy, buy, how many points?" Rong Bing decisively decided, he was very happy to be able to do something for the earth!"

"After deducting five hundred host points, the system mall will provide the host with relevant information on Chinese sturgeon and white porpoise.

Rong Bing immediately immersed his mind in the system space, and said to the grid where the information was placed: "Study!"

Suddenly Rong Bing felt his brain swell, and a lot of knowledge was fused with his memory like an enlightenment.

Rong Bing sat in the car and recalled, about half an hour later, he finally understood the living habits of Chinese sturgeons and white porpoises and how they lay eggs.

Originally, the spawning period of Chinese sturgeon needs to be in a river with a water temperature of 18.0-20.5 °C, a sand content of 0.715-0.915 kg/m3, a flow rate of 2.2-2.6 m/s, a transparency of 4-6 cm, a pH of 8, a dissolved oxygen content of 9.2 m/L, and a water depth of 5-19.8 m.

Sturgeon lay sticky heavy eggs, which lay on the gravel to hatch. Mature oval oval, greenish-brown. The egg diameter is about 3.6 mm. Fertilized eggs hatch after 123-140 hours at a water temperature of 17-18°C. After spawning, most of the broodstock quickly leave their spawning grounds to inhabit downstream and estuarine areas.

After spawning, the female broodstock descends the river very quickly. Broodstock sturgeon mostly stop feeding during the reproductive period, and the eggs produced are sticky, sticking to the rocks or gravel at the bottom of the river, and the fertilized eggs hatch for about 5-6 days and nights at a water temperature of 17-18°C.

"It turns out that this is not the spawning ground of Chinese sturgeon, no wonder you can't find fish eggs!" Rong Bing smiled and beckoned Wangcai and Xiaofeng to get into the car.

He threw hundreds of Chinese sturgeons into the domestication pond and drove to find the spawning grounds of the Chinese sturgeons.

The size of the Chinese sturgeon is very large, even ordinary individuals can grow to about 1.3 meters, the largest can even reach about 5 meters, and the weight is comparable to that of small and medium-sized sharks up to 600 kilograms, which is the largest fish in the Yangtze River basin, almost dominating the entire Yangtze River, and is also known as the king of fish.

It is also a migratory fish, so it will stay in the Yangtze River for 12 months before returning to its spawning grounds, but it does not swim up the river all the time, but stops and goes, sometimes even for days in the depression.

When they are young, sturgeon feed on insects such as mosquito larvae and dragonfly larvae, and sometimes even plant detritus.

Therefore, as long as Rong Bing finds a low-lying place with abundant aquatic plants, he can basically encounter sturgeon eggs.

After driving and searching for more than an hour, Rong Bing finally saw overgrown weeds and low trees standing ...... under Heti

"This place seems to be a spawning ground, go down and have a look......"

Rong Bing drove on the riverside road, directly over the fence and down to the river.

Sure enough, he saw many Chinese sturgeon eggs in the riverbed.

"That's great!"

But soon Rong Bing became distressed again, how should he collect these fish eggs that were adsorbed on the riverbed?"

"System, is there a special tool for collecting these fish eggs?" Rong Bing had no choice but to continue to ask for help from the system.

"Yes, the host can buy a fish egg collection robot in the system mall, and you can collect any fish eggs for the host in any river!" The system's voice sounded in his head.

"Damn, if you didn't say this kind of good thing earlier, it would have caused me to run so far in vain!" Rong Bing was suddenly unhappy, feeling that he had not only run the wrong way, but also spent the wrong points to buy materials.

"The host didn't ask?" the system's voice was full of disdain

!"I......

" Rong Bing was speechless!

"How many points does that robot have?

After deducting 20,000 host points, five fish egg collection robots have been purchased for the host, please check them in the system space. The system immediately answered.

"What, why is it so expensive?" Rong Bing's heart was dripping blood, and 20,000 points were gone

! The system didn't take Rong Bing's attention, and Rong Bing had no choice but to accept it!

This fish egg collection robot can not only collect at the designated location, but also collect the whole river basin together.

Five robots were set up to collect Chinese sturgeon eggs in the whole basin, and Rong Bing put them into the Yangtze River, waiting to come back to Earth to collect them.
