Neiji and Tenten

After a while, Ning Ci and Tian Tian came to a river with relatively fast current.

This is the river Neji deliberately chose.

Because with Neji's control over Chakra and physical fitness at this moment, generally calm waters can no longer achieve much exercise effect.

Only this kind of river with relatively turbulent water flow can further improve one's control over chakra and carry out in-depth and comprehensive physical fitness exercises.

At the same time, it can also increase the difficulty of practicing shooting fish in the water every day.

Sure enough, when Ningci turned his head to look at Tiantian.

At this moment, Tian Tian's face no longer had the confidence he had before, and there was a little more embarrassment!

This kind of deep waters and turbulent river, without Bai Yan's assistance, it is really not a simple matter to hit the swimming fish in the water with ninja tools.

Even Neji himself at this moment, it is difficult to do this without the help of rolling his eyes.

Because this not only requires high throwing accuracy, but more importantly, keen insight and precise timing control.

A series of elements are superimposed together, and the difficulty directly increases exponentially.

But it doesn't matter if it's difficult, if it's really not difficult at all, then what more practice is there?

"Haha, don't back down,"

Looking at Tian Tian's ever-changing expression, Ning Ci teased with a very bad taste: "You said it yourself, the fish tube is enough..."

"Humph,"

Tian Tian's expression, which was still tangled just now, instantly turned into a face of blame, and he said in protest: "Brother Ningci played tricks, how could he hit the target with such a fast current!"

"That's not sure. It's worth practicing only if it's difficult. Otherwise, I've been practicing some relatively simple target shooting, but it's hard to have room for improvement."

What Ning Ci said is not nonsense, the goal is [-] points, even if he only completes half of it, he can still get [-] points.

If the goal is only [-]%, even if all of them are successfully completed, it is only [-]%.

This is the difference between hard training and low difficulty training.

Although Tiantian sometimes likes to act like a baby, she looks like a little girl.

But he is not an unreasonable person, and sometimes he is even very sensible.

Just like at this moment, after listening to what Ning Ci said every day, he didn't find any other reasons or excuses to shirk.

Instead, he took out all the throwing weapons he carried with him, and began to carefully observe the river in front of him, thinking about countermeasures.

And Ning Ci didn't delay. After taking off his coat and shoes and socks, he jumped and plunged directly into the river.

Ning Ci's move made Tian Tian jump in fright.

It was very dangerous for Neji to plunge into such a fast-moving current for a child under the age of six.

If one fails, it will be washed away by the current...

But fortunately, after Ningci entered the river for a while, his head popped out, causing Tiantian on the shore to heave a sigh of relief, and almost started calling for help.

As for Ning Ci's next move, he was stunned every day.

Ning Ci actually swam against the current, and his freestyle posture made Tian Tian's eyes sparkle again and again.

The most important thing is that Neci's swimming speed has reached a perfect balance with the speed of the water.

Let the distance between Ningci and Tiantian on the shore at this moment remain unchanged.

'Is this the exercise of Brother Ning Ci? Tian Tian murmured in his heart: "It's really unbelievable." '

In fact, what Tiantian didn't know was that this was Neji's first time swimming in this life.

The reason why Neji is so skillful at this moment, using the freestyle posture to fight against the rapids in the water, is entirely due to the advantage of growing up by the river in his previous life.

Today, the conjecture that Ning Ci intends to verify, the first step is to consume all of his physical energy, and even push his limit.

Swimming against the current is a relatively good exercise. Not only can it exercise most of the muscle groups in the body, but its training intensity is also very exaggerated.

1 minute, 2 minutes... 5 minutes passed in the blink of an eye, and Neji's body began to feel a little tired, but he didn't reach his limit.

After 6 minutes, 7 minutes, and 8 minutes passed, Ningci's hands began to lose control, and he couldn't maintain a relatively still state with the shore.

Ning Ci gritted his teeth, resisting the urge to mobilize the chakra in his body, and prepared to continue, intending to further challenge his limits.

It wasn't until the tenth minute that Neji decided that he had slightly broken through the limit, and swam decisively towards the shore.

Another 2 minutes passed, and when Neji struggled to climb ashore, he almost collapsed.

The muscle groups all over the body felt sore and unbearable, like the pain of being pierced by steel needles.

Ning Ci knew that it was because of the excessive exercise that he had just done, which caused a huge amount of lactic acid to be secreted in his body.

Fortunately, a small amount of lactic acid can be metabolized by the human body in time, and it will not cause any harm to the body.

However, the huge amount of lactic acid substances cannot be easily digested by the normal metabolism of the human body.

Under such circumstances, if one does not handle it properly, it may even cause permanent damage to the body's muscle groups.

But Ning Ci, who knew all this well, naturally wouldn't just watch his muscles being corroded by a huge amount of lactic acid.

Not daring to delay, Ning Ci immediately opened his white eyes and looked inside, quickly finding out the area with dense lactic acid substances.

Then mobilize the chakra in the body and start to swim in the lactic acid dense area, and wipe out the huge amount of lactic acid produced due to excessive exercise one by one.

This is a very patient job, and it can only be completed with the help of Bai Yan.

Because a huge amount of lactic acid is not evenly distributed in the body, but varies from person to person, exercise method, and exercise intensity.

Ning Ci, who had expected this for a long time, was not in a hurry, so he endured the pain all over his body, sat upright on the shore, and began to obliterate the lactic acid substance wholeheartedly.

Until more than half an hour passed, when the last mass of lactic acid that Bai Yan could observe was wiped out by Chakra.

The muscles that were sore just now are almost the same as usual except for a little numbness.

After repeatedly confirming that his body was fine, Neji's heart couldn't contain the ecstasy at this moment.

Because when doing physical training, the previous 80.00% of the training volume does not have much effect on the improvement of the body.

Only when a person's physical energy is about to be exhausted, and then he grits his teeth and persists, constantly breaking through the limits of the body, can a person's physical fitness be rapidly strengthened.

However, the process of breaking through the limit of the body will be accompanied by the secretion of a huge amount of lactic acid.

If this lactic acid substance is secreted too much and it is not cleaned up in time, it will cause huge damage to the human body.

This damage can even become irreversible if you do this for a long time.

This is why, the physical education teachers in the previous life would repeatedly emphasize the phrase 'too much is too late', and did not advocate intermittent overload training.

However, just now Neji verified one of his conjectures through personal experiments.

That is the conjecture that chakra is used to obliterate lactic acid substances.

Sure enough, my guess is indeed correct:

First of all, Baiyan can accurately find out the lactic acid substance hidden in the body muscles.

Secondly, the use of chakra can indeed wipe out lactic acid substances.

Finally, once the lactic acid in the body is wiped out by chakra.

Although due to excessive exercise, the muscles, bones, and meridians in the body will still be exhausted to a certain extent, but this exhaustion is far weaker than the harm caused by lactic acid substances.

Ningci initially estimated that if he didn't use chakra to wipe out the huge amount of lactic acid, he would need to rest for at least a week before his body could return to normal.

After erasing the lactic acid substance, Ning Ci can be sure that he will be able to recover in the morning tomorrow.

The recovery speed has been fully increased by seven times!

This also means that I can carry out a training that breaks through the limit every day.

Thinking of this, even Ning Ci, who had always been extremely calm, couldn't contain his ecstasy.

Although I traveled to the world of Naruto, I didn't get the system, and I didn't have the so-called cheats and 'grandpa'.

However, relying on the advantages of vision, knowledge and foresight in the previous life, Neji is still confident that he can live a wonderful life in this life.

……

After moving his body a little, Neji suddenly felt a little hunger in his body.

Suppressing the joy in his heart, Ning Ci took out the supplement pills and nutrition package that he had prepared in advance, called Tian Tian who was also in the training state, and had lunch together.

"day by day,"

During the meal, after Ningci thought for a while, he planned to share the results he had just obtained with Tiantian: "In the afternoon, you can also try swimming against the current and challenge the limits of your body."

"Do you want to challenge the limits of your body?"

Just now Tiantian saw Neci's crazy training state with his own eyes, and now he heard Neci's words, his heart began to beat.

Because half a year ago, when I was practicing ninja throwing every day, because I was too involved, I unknowingly carried out an overload training.

As a result, although Tian Tian's ninja throwing skills have improved, it took more than a week for Tian Tian to recover.

If it wasn't for the severe exhaustion of physical strength every day at that time, and the timely cessation of cultivation, otherwise it may cause irreversible damage to the young body.

It is also because of this that although Tian Tian has been training on the sidelines just now.

But he always noticed Neji's side, fearing that Neji would be injured due to over-training.

"don’t worry,"

Ning Ci saw Tiantian's hesitation, and continued to speak: "I have a way to eliminate the negative effects caused by excessive exercise."

As Ning Ci said, he stood up, moved his body, and proved it to Tiantian with facts.

"Wow……"

Seeing that Ning Ci was fine, Tian Tian cheered immediately, and asked curiously: "Brother Ning Ci, how did you do it!"

"The last time I was in pain for more than a week because of over-training, I was so uncomfortable..."

"I won't tell you yet, you'll find out in the afternoon." As he spoke, Ningci took another big tonic pill, and a bitter taste immediately filled Ningci's entire mouth.

Even though this thing has been eaten for two or three years, it is still so unacceptable.

Moreover, because of the over-training just now, Ningci had to increase the amount of Dabu Wan to eat at this moment.

Really painful and happy!
