Wu electrician's children are all married, working in other places, and he and his wife help his son and daughter-in-law take care of their grandchildren during the winter vacation.

After retiring, he had nothing to do, and planned to have some fun and think about fish farming.

So, he quickly set up a fish tank and equipment, a lot of which he bought from this store, and the price was moderate, cheaper than not shopping online, but elderly people like him still prefer to buy in physical stores when the price gap is not large.

The first time he raised fish, he didn't dare to raise too expensive fish, for fear of wasting money if he couldn't raise it, so he bought a few cheap saltwater fish to practice - as for why it was a saltwater fish instead of a freshwater fish, because he heard other old people who exercised together say that it is better to raise freshwater fish before drying the water, it is better to raise saltwater fish directly, anyway, we are very close to the sea, and it is good to ride an electric tricycle to the beach to pick up a few buckets of seawater, and even the water bill is saved.

When Electrician Wu heard it, it was really such a reason, his wife was not very willing for him to raise fish, because it was too much water and electricity, and if she raised saltwater fish, she would be able to reduce half of the nagging - yes, just raise saltwater fish!

Binhai City is still expected to be cold in spring, and the indoor is not warm, and the tropical saltwater fish he bought need a water temperature of at least about 25 degrees, and the heating rod is indispensable, even if his wife nagged and spent electricity.

In the beginning, the fish farming went well, and he spent most of his day tinkering with his fish tank, and he enjoyed it, except for his wife who nagged him all day long about his lack of work and threw all the tasks of taking his grandchildren to her.

Soon, the fish tank took shape.

Wu Electrician stands in front of the fish tank every day, looking at the fish tank he has arranged with bottom sand, live stones and coral, and several small fish of different colors swimming around in the water, his heart is full of relief and a sense of achievement.

Neighbors and former colleagues occasionally come to visit the door, and when they see the fish tank, they are full of praise and praise for his ability to tinker.

After coming and going, his wife gradually stopped nagging, and sometimes even took the initiative to help him feed the small fish.

The small fish grow very fast.

Wu Electrician has been pondering in recent days, it seems that he has a talent for fish farming, these ordinary small fish can no longer satisfy his appetite, maybe it's time to get a few good fish, it will definitely attract more envious eyes from neighbors and former colleagues.

He had grass growing in his heart, and when he had nothing to do during the day, he would ride his bicycle and run out, searching for fish markets and a few aquariums, shopping around and comparing prices for high-quality saltwater fish that was worth the money.

However, in the past two days, the little fish seem to be a little abnormal, they do not sleep day and night, and they are always jumping around in the fish tank, almost non-stop.

Wu Electrician was a little worried when he saw this, and wondered if the fish were sick.

He felt that he had not yet worked to raise fish, so he temporarily postponed his plan to introduce high-quality marine fish.

One day, he bought a reference book on common diseases of marine fish from the bookstore and came home, ignored his wife's complaints, and played with his little grandson.

The little grandson is very well-behaved, and he is very good at studying, he usually makes people feel at ease, he likes fish, he likes to watch Wu electrician raise fish, he never makes trouble when he fiddles with the fish tank, he always watches quietly on the side, and also takes on the task of changing the water in the fish tank.

Wu Electrician has always loved his little grandson and regarded him as a pearl in his palm.

While playing, the little grandson suddenly pulled his arm and said mysteriously, "Grandpa, you put your hand in the fish tank." ”

Electrician Wu was peeling apples, and felt that it was unhygienic to put his hands in the water, so he smiled and said, "What are you doing with your hands in the fish tank? Grandpa will peel apples for you." ”

The little grandson seemed to have been recognized as if he had been spotted by a well-planned game, and he reluctantly pulled his arm and said coquettishly: "Grandpa, stretch it out!

Electrician Wu smiled happily and couldn't bear to refuse, so he put down the half-peeled apple first, and when he saw that his wife didn't pay attention, he quietly wiped his hand on his pants.

"Okay, well, let's see what my precious grandson wants to play......" he smiled and stood up, reaching for the surface of the fish tank.

The moment his fingertips entered the water, the numb feeling instantly spread throughout his whole body like electricity!

"Ahh

He was so shocked that he quickly withdrew his hand.

This feeling is too familiar to him, it is a leakage! And judging from the degree of numbness, the current intensity is not small!

"Hee-hee!"

As if the ploy had succeeded, the little grandson clapped his hands happily and laughed: "Grandpa! Grandpa!

As he spoke, he stood on tiptoe and tried to put his hand in the water.

Electrician Wu grabbed his little hand, "Don't touch the water!"

His tone was probably not very good, and his expression was certainly the same, and the little grandson stared at his face, and couldn't help but be a little scared.

"You dead old man, what are you doing to scare the children!" The wife was dissatisfied, and crossed her waist and reprimanded: "You wander around outside all day, don't do anything at home, and go home to scare the children, do you think you are going back more and more?"

Wu electrician didn't care about arguing with his wife, and nervously grabbed his little grandson's hand.

He was so frightened that his head was covered with cold sweat, and he said in a trembling voice: "Child, when did you find out that you were numb?"

"Grandpa, my wrist hurts......" The little grandson tears rolled in his eyes aggrievedly.

Electrician Wu relaxed his strength, but still didn't completely let go, "Tell grandpa, when did you find out?"

The wife noticed his strange appearance, and her heart suddenly shuddered, and she watched the conversation between the two men with trepidation.

The little grandson thought for a moment, "When I changed the water yesterday morning. ”

"Yesterday morning, the water was numb?" confirmed Electrician Wu.

"It's not very numb...... A little numb...... Not numb today. The little grandson replied.

Three sentences express the same meaning - today's electricity leakage is more serious than yesterday's.

Electrician Wu's heart was about to break, if the little grandson didn't let him put his hand into the water today, or if he didn't put it in just to peel apples, would the electricity leakage be more serious tomorrow? Will it be ...... tomorrow when the child changes the water?

He didn't dare to think about it anymore.

He couldn't wait to beat himself a few fists - a dignified nationally certified electrician, seeing Xiaoyu scurrying around in the fish tank all the time, he didn't expect that it might be a leakage, but he suspected that Xiaoyu was sick?

It's really special, a handful of years old to live to a dog!

If the little grandson has three longs and two shorts, the son and daughter-in-law will have to die of distress, and he will have no face to live.

The wife asked the reason, and was so frightened that she almost fell to the ground, held the little grandson in her arms, and complained with a handful of snot and tears that he shouldn't raise fish, and almost killed her baby grandson!

Wu electrician's heart is bright, this is not a problem of fish farming at all, it is something leaking in the fish tank.

As an electrician, he always has an electric pen at home.

Sticking an electric pen into the water of the fish tank, the pointer jumped directly to more than 70 volts.
