"Okay coach, I'm sorry!" The big-mouthed Liu was stunned for a moment, and casually hit the ball in his hand.

However, when the ball was hit, he found that his ball actually felt like he had practiced in the past, instead of giving a 60-kilometer shot as Chu Danjiang requested.

The big-mouthed Liu hurriedly apologized, he was really shocked by Chu Danjiang's domineering hit just now.

His former coach told him that Jingwu private coaches are powerful, which is to lose weight and keep fit, I dare not say that I can reach the professional level of level 7, but ordinary high school students must only be abused!

Bigmouth Liu has practiced tennis for so many years, and even won many good results in provincial and municipal middle school competitions.

But in the tennis rating, he has only just crossed the threshold of level 4.

Ouyang Tianming is also similar to him, although the two of them have their own technical strengths, but on the whole, they have only just crossed the level 4 threshold.

Standard tennis starts at 1 and is divided into 0.5 grades.

If a technology exceeds the grading standard, it can be increased by 0.5, otherwise, if it does not meet the standard, 0.5 or even 1 point will be deducted to determine which level it is currently on.

Level 1-2 does not need to be assessed, and basically you can be regarded as a novice.

It's good to be able to hit the ball back consistently.

However, after reaching the 2.5 level, the improvement in tennis strength can be seen with the naked eye.

The most obvious difference is that level 2.5 can barely start to control and find the right style of play for you.

It's not like a headless fly like before, you can hit the ball when you have it, and you can hit it back into the opponent's bounds.

If you are talented, then it is not difficult to cross level 1-2, if you can train intensively and have a coach, you may be able to cross this obstacle in 1-2 weeks.

But after 2.5, if you want to improve, you need to train hard and be supported by talent.

The transformation process from being able to fight well to playing well and fighting well is not something that can be completed in a short period of time.

One year is the shortest cycle.

From being familiar with the basic techniques of tennis, and then constantly training to improve his accuracy, Bigmouth Liu knows exactly how long it took him to cross the threshold of 2.5 and 3.

The 3.5-level Big Mouth Liu can already achieve a certain ranking in the district competition, and it is at this time that the Big Mouth Liu begins to feel the fun of tennis more and more, rather than just a hard training.

The victory can be said to be an important reason for the big mouth Liu to officially enter 4.0 in middle school and show his standing in the municipal competition.

And this level is enough for him to even get a good ranking in the adult amateur competition.

Of course, this competition is only in China where the overall tennis level is still relatively low, not those areas where tennis is developed, and even ordinary amateurs may have received special professional tennis training when they were teenagers, even if there is no obvious improvement after that, but it can still be maintained at the level of 5 to 5.5.

This level has almost touched the threshold of the profession, if you are lucky, you can even play the professional qualifiers at the level of the hope tournament, play in the main competition, and win a professional point!

Is there such a monster in Jingwu Private School?

Of course, Big Mouth Liu has seen the outcome of the sweep of the Gu Emperor in the city several times, and those peers who are obviously good in strength, or even above him, are not Gu Di's opponents at all.

Even if the strength of the ancient emperor does not reach 5.5, it is already about the same, this is the strength of the crushing level among high school students, and almost only the genius powerhouses in several other famous schools are qualified to be his opponents.

But what did he see today?

Chu Danjiang was in such a state, showing a strength that was not inferior to that seen in the ancient emperor.

It's just the same as when he saw Horay, it's so unreasonable.

The batting continues!

Slowing down?

Chu Danjiang didn't care at all, since he didn't have the strength to borrow, he could only exert some strength by himself.

He let Big Mouth Liu hit the ball so quickly not to show off his skills, but to make it easier for himself to borrow the power of the incoming ball, so that he could hit the ball more easily in the future.

Are you too lazy to get home?

But in terms of technology and strength, Chu Danjiang has lazy capital!

Location in Horay!

Chu Danjiang's shot accurately found the position of the corner of Hooley, this ball was different from the flat shot just now, but a very strong forehand topspin with a topspin.

The bouncing and just now completely present the two extremes, and what makes the viewer feel even more worrying is that the angular landing point is pressed to the position where it just lands on the right corner boundary!

The bouncing ball almost exceeded the topspin ball in the chest, and pressed against the baseline again.

If the ball retreats deep, you can only catch the shot that has already exhausted its strength and started to fall.

In the game, this kind of form ball will not only fail to play a strong counterattack, but will also give the opponent more time to prepare for the reaction.

Completely inconsistent with the concept of playing the rising point in modern professional tennis.

Only the ball that is still rising after bouncing will be able to hit back with stronger spin.

It's not magic, it's not tennis technique, it's a real foundation of mechanics.

Playing the ball from the bottom up with the racket and the tennis ball bouncing from the bottom up, the two points are exactly at a standard T-angle during the handover.

Such an angle means that the optimal balance is achieved not only in terms of power, but also in terms of rotation.

However, if you wait for the ball to fall, the racket can only create a T-shaped angle with the ball towards the air, which can still play spin and power.

But the direction is towards the sky......

The flight time is longer than hitting the ball at the ascent, and the extra time is embarrassing in the pursuit of faster, higher and stronger competitive sports.

And what about catching the ball early?

Kid, you're too naïve, if you're really so good at picking up, what kind of profession is non-professional top non-top.

Everyone understands the reason, but won't the opponent play tricky angles, so that you don't have time to hit the best rising point?

Don't look at the weakness of the big mouth Liu's ball, but Chu Danjiang's hitting position is a proper standard rising point.

Hooray was faced with a goal that was not only difficult to catch, but also uncomfortable.

And Chu Danjiang deliberately investigated Huo Lei, and pressed the landing point of the ball very close to the bottom corner.

As for whether it will be out of bounds?

They're not playing.

It's a big deal if it's out of bounds, I'm fighting again, he's a lot more hooligan than Zhou Wenchang.

The psychological burden was lost as early as 800 years ago, and it was not the first time that the festival was lost.

Huo Lei's movements were fast, but the movements under his feet seemed a little chaotic to Chu Danjiang.

It's not a traditional cross-step movement, but the landing speed is not bad at all.

Yes, in an instant, Horay was in place, and his racket was swinging, and the direction was not towards the sky like before.

Hooray is finally going to hit the ball for the first time!
