Frog eggs and toad eggs develop from egg form to tadpoles under normal circumstances, but because Fang Ziyu specially made the water temperature in the wooden barrel very low, the development rate of frog eggs and toad eggs slowed down a lot.

To this day, there are still small tadpoles that have developed.

Although frog eggs and toad eggs are easy to distinguish, Fang Ziyu still put waterproof labels on their respective fish tanks. And the eight small partitions of each large fish tank are labeled with digital waterproof labels from one to eight sizes.

After sticking to the post, Fang Ziyu began to process the frog eggs, he wanted to get more female stray frogs, Fang Ziyu scooped some ice water from the wooden barrel and poured it into the eight small sections of the frog breeding tank, reducing the water temperature to 16 to 20 degrees Celsius.

The suitable temperature for the development of frog eggs is 20~26 degrees Celsius, and it is difficult to develop below 15 degrees, or the development is slow. Temperatures below 10 degrees and over 30 degrees will cause the eggs to die.

Fang Ziyu remembered that he went to high school later, and he specially bought a thermometer and measured the water temperature in the mountain stream where he found super tadpoles in junior high school, and it was eleven or twelve degrees all year round.

Fang Ziyu estimated that there should have been at least a few hundred eggs there before, and the reason why there was only one super tadpole left was that the water temperature was too low and the others died.

After thinking about it, Fang Ziyu still missed the super tadpole in junior high school, and gritted his teeth and mixed ice water into the small tank No. 8 of the frog tank, reducing the water temperature to eleven degrees.

After adjusting the water temperature, Fang Ziyu asked Xiaoice to come over and reduce the overall temperature of the storage room to 20 degrees Celsius, which would not cause the temperature convection to rise too quickly in the breeding tank.

In order to save money on air conditioning, the Xiaoice specially condensed a Xiaoice mountain composed of ice elements in the middle of the house, which is not easy to melt and can control the indoor temperature at a reasonable level.

After doing this, Fang Ziyu found a large basin and carefully turned out all the frog eggs in the big wooden barrel, in fact, there were not many frog eggs, and the main reason why Fang Ziyu couldn't hold it was that the bucket made of live wood was too heavy.

Carefully picked out more than 200 eggs and put them into the frog tank No. 8, the frog tank with a temperature of only 11 degrees, and then divided the other frog eggs into the other seven frog tanks.

Then turn on the oxygen pump, provide enough nourishment qi, and slowly wait for the frog eggs to develop.

As for the toad egg, this Fang Ziyu is completely used for experiments, he wants to see how the toad egg sprinkles the crystal nucleus of different attributes into its water during the development process, adjusts different temperatures, and sees what the toad's attributes will be like after birth.

To this end, Fang Ziyu first adjusted the water temperature of all the seven small tanks in the toad tank to fourteen or fifteen degrees, so that it could develop slowly and have enough time to absorb the crystal nucleus powder that Fang Ziyu sprinkled in.

There is also a small toad tank numbered (8) that regulates the water temperature to 10 degrees, the lowest development limit, to see how big tadpoles can be raised.

After getting these tadpoles right, Fang Ziyu closed the door of the storage room and came out, preparing to crush some crystal nuclei for experiments, it is said that because of the revival of the aura, the probability of these oviparous animals mutating during development is much greater.

"Brother Fang, my son Chen Chen is here, please help him take a look at his pet. Seeing Fang Ziyu come out, Chen Feng hurriedly stepped forward and said.

"Okay, no problem. Fang Ziyu wiped his hands and looked at Chen Feng and the young man behind him.

Chen Chen is very similar to Chen Feng, with a height of one meter seven, and his pet is a long-haired dog with cyan hair, the breed cannot be seen, it should be a skewer.

Fang Ziyu always felt that this Chen Chen was a little familiar, as if he had seen it somewhere, especially this green-haired dog was more impressive.

Chen Chen looked at Fang Ziyu with a shocked expression on his face, as if he couldn't believe how Fang Ziyu could appear in a pet shop. Seeing Fang Ziyu looking at him, he hurriedly greeted: "Hello examiner teacher." ”

"Hmm, examiner teacher?" Chen Feng heard his son call Fang Ziyu Examiner Teacher, and looked puzzled, Examiner? Fang Ziyu is an examiner? Didn't he also go to take the assessment?

"Dad, that's the case, the examiner in charge of my assessment area is ......" Chen Chen smiled bitterly and explained to his father Chen Feng.

Chen Chen heard his father Chen Feng say how amazing the manager of the pet store was, and there was a giant dragon pet, but he didn't care too much about it, and he didn't believe it, but he didn't expect to come over and see that it was actually the examiner in charge of the assessment?

It turned out that the examiner lived not far from his home, and he never knew about it.

Chen Feng, who understood the cause and effect, turned his head and looked at Fang Ziyu with a flurry of words: "Old Fang...... Teacher Fang, is he still an examiner at the Advanced Summoner School?"

Hearing Chen Chen's greeting, Fang Ziyu realized that he should be the young man he had seen in the wilderness assessment, and he also happened to be in the assessment area he was responsible for.

"Haha, sort of, it's not a big deal to be invited over before. Fang Ziyu scratched his head and said.

In front of Xiao Bai, who knows people or peers, Fang Ziyu likes to pretend to be forced, but in front of some unfamiliar people, Fang Ziyu will instinctively cover it up. The main thing is that if he goes around and advertises that he is an examiner, he will be like an upstart, too embarrassing, too disgraceful.

Although this kind of recognition and looking at the surprised expressions of the two people had a kind of pleasure of pretending to be invisible, Fang Ziyu assured that he didn't mean to pretend to be forced, who let him be recognized.

"Teacher Fang, Lao Chen, I really didn't know Taishan before, I didn't see that you were the examiner, please forgive me. Chen Feng hurriedly explained with a smile, and lowered his posture a lot. He clearly knew what it meant for Fang Ziyu to be an examiner at the Advanced Summoner School, it wasn't just a matter of identity.

His current attitude was like that of an ordinary person receiving a leader in the government, looking at Fang Ziyu with a soft smile on his face.

"Haha, don't talk about this, are you going to help this pet dog advance?" Fang Ziyu changed the topic, although Chen Feng's attitude was very refreshing.

"Yes, yes, yes, it's to help Chen Chen's dog advance and trouble Teacher Fang. Chen Feng said with a smile.

Chen Chen pulled him over and said with a smile: "Hello teacher, trouble teacher." ”

"You seem to have been besieged by the trolls because the shelter was built on the way for the trolls to feed, and then you were eliminated?" Fang Ziyu glanced at Chen Chen, squatted down and pressed his hand on the head of the green-haired dog.

"Yes, that's how it was eliminated. Chen Chen also squatted down and pulled the dog, and said embarrassedly.

Chen Chen actually admired Fang Ziyu very much, and Fang Ziyu left a very deep impression on many students when he rode a 17.3-meter-long dragon to patrol and wander over the assessment area.

Fang Ziyu didn't know, but in fact, many students admired him very much, especially in the last few days, Fang Ziyu commanded the giant dragon to easily hunt the figure of the third-order troll.

At this time, being able to get in touch with Fang Ziyu at close range, Chen Chen was a little excited.

"Go back and learn more about wilderness survival, you can watch Bei Ye's video, he explained it very carefully about wilderness survival. Fang Ziyu nodded and said, and at the same time turned on the detection ability.
