When he got home, Li Shi checked the logistics information on the mini program to see where the high-speed camera he ordered online had gone.

Then I went to a procurement network to take a look, and when he was still in Yangcheng, he found a manufacturer of automatic induction wireless laser timers on this platform, and they sold professional electrographic equipment.

However, their equipment needs to manually control the speaker to give instructions, Li Shi left them a message last time, asking if they could add an automatic countdown function.

Open the customer service, the manufacturer has replied to the message and sent a new link.

Click on it and see that it is a new version they have put on the shelves, and there is an additional function of automatic ten-second countdown - press the new countdown button on the remote control, after ten seconds of time, the command speaker will simulate the sound of the starting gun, and at the same time order the laser induction timer of the two sections of the runway to start timing through radio waves.

Li Shi looked at the price again, okay, there is a small function, and it has increased by 1,200 yuan.

More than 19,000, Li Shi placed an order to buy a set and asked them to ship it quickly.

In the next three days, except for signing a supplementary agreement with the engineering company, he spent the rest of the time at home reading books, watching videos, and training in place.

A few couriers were received in the middle, and the starting gear, high-speed cameras and electrophone equipment arrived one after another.

In the evening of that day, after the construction workers had left the site, Li Shi drove alone to the activity base with all the equipment.

After this period of renovation, the activity base has changed a lot.

In addition to the sports field, which has been completed for the most part, the previous hollowed-out gate has also been replaced with an electric large iron gate that can block the view, so that people outside can not see the inside.

After closing the door, Li Shi turned on the sports lights in front of the two buildings, and the area around the 50-meter track suddenly became as bright as day.

An old desk was brought from the classroom, and a laptop was placed on top of it, and two kettles with plain water and sports drinks were placed at the foot of the desk.

Then take the trunk of the car and remove all the equipment.

Whether it is a high-speed camera or an electrophone device, since he got his hands on it, he has been studying it at home for a long time, and he quickly installed and debugged it skillfully.

Everything is ready to go.

Li Shi began to warm up on the runway, stretching his body while adapting to the new runway.

After the thirty sets of movements were completed, he came to the front of the starting line, pressed the countdown button of the remote control, and then stepped on the starting gear to make final preparations.

This is the first time he has officially used a starting point and electrogram equipment to run on a plastic track!

Ten seconds later, an electronic tone came from the speaker next to me:

"Ready!"

"Ready!"

"Smack!"

Li Shi heard the sound of the simulated command gun, and his body was like an arrow off the string, rushing out!

This time, he didn't have anything to hide, the muscles of his whole body were mobilized, and there was only one thought in his heart, accelerate, accelerate, accelerate!

One meter, five meters, ten meters, twenty meters!

Li Shi's speed is getting faster and faster, but his acceleration does not stop, and his strong endurance supports him to directly pull his acceleration distance to thirty-five meters!

After reaching the top speed, he used the mid-running technique to stabilize seven or eight meters, and then quickly transformed and sprinted!

In the last few meters, in the blink of an eye, he quickly crossed the finish line, trotted forward for some distance to buffer, stopped, adjusted his breathing, and couldn't wait to look at the electronic display.

The electronic display is small and displays a clear red number: 5.88

5.88 seconds!

Li Shi smiled, just this trip, he could feel that his start was a little slow, if the start was a little more agile and the technique was better, he should be able to be faster.

In addition, after running with all his might, the imitation of Tyson Gay's technical movements began to deform, and it was not as easy as he imagined to control his body at high speed.

"You have to do it with a lot of practice."

He looked at the image of his start and the first few steps under the lens of the high-speed camera on the computer, and checked the details of the action frame by frame.

And contrast it with the action with Geison Gay.

"In the first step, the swing of the left hand is not in place."

……

Practice hard and open your liver!

With his strong physical strength, Li Shi started at seven o'clock, constantly repeating the start, as well as the acceleration practice of the first few steps, until half past twelve, before packing up and going home.

There were few cars at night, and it was not yet one o'clock in the morning when he returned to Phoenix Bay, so he took a shower and quickly fell asleep.

The next afternoon, Li Shi was studying the video of his own training last night when he received a courier call.

"Hello, is this Mr. Li Shi Li? Your rice has arrived, when will you have time, we will deliver it to your door. ”

Li Shi was stunned, I didn't buy rice, I don't usually cook, how can I buy rice.

"Are you mistaken?"

The courier brother over there quickly reported the phone number and address, and when he heard it, it was indeed his own information, and suddenly remembered that Chen Qiuye had said that he had mailed a gift to himself, and hurriedly asked: "Is it sent from Bingcheng?" ”

"Yes, that's right, the shipping address is Bingcheng Zhengfang County."

"Oh, then wait a minute, I'll ask here, and I'll call you back later."

Forty minutes later, Li Shi looked at the mountains of rice from the Northeast in front of him, and he couldn't laugh or cry.

took a photo with his mobile phone and sent it to Chen Qiu.

"I never thought that the gift you said was this! (thumbs up)"

Chen Qiuye immediately replied to the message: "Hehe, a distant relative's family planted it is considered selenium-rich rice." ”

She had something else to do over there, so she chatted a little bit.

Li Shi picked up a bag of rice and came to the kitchen and cooked a pot in a rice cooker.

When the rice was cooked, he took out four eggs from the fridge and made a scrambled egg.

He actually cooks a little food, but it doesn't taste very good, and now he doesn't have to save money, so he usually doesn't bother to cook.

When I opened the rice cooker, I immediately had the aroma of rice coming to my face, and I made a small ball with a rice spoon and put it in my mouth, well, it was good, the taste was soft, slightly sweet, and very fragrant.

Four eggs drained a pot of rice, and Li Shi ate it deliciously.

After eating, he drove to the activity base again and continued to imitate the training.

Last night I practiced starting and accelerating, and a few days I practiced running and sprinting in the middle of the practice.

The two practiced more smoothly, and at ten o'clock, he stopped to rest for half an hour, and at half past ten, he did a few sets of warm-ups again, and then stood in front of the starting line again.

So far, he has imitated the whole course technique of starting, accelerating, running and sprinting on the way, the four 50-meter and 100-meter skills.

"It's been a lot of progress in the past two days, let's see how much I can run now."

"Ready!"

The command speaker sounded, Li Shi took a deep breath, and with a "pop", he rushed out.

After a few seconds, he gasped and stood still, feeling that the run was good, whether it was the acceleration of the start, the middle run and the final sprint, the technical movements were well imitated.

There should be a new record.

Before I could look back at the screen, something suddenly crossed my mind.

He looked overjoyed and was promoted!

When I called out the learning panel, I was directly stunned, this time I actually rose two small levels in a row!

The second more
