Fortunately, Tsunade is not working at her desk or gambling everywhere, so Ding Ding found her in a tavern.

"Yeah, I've fooled someone so soon?" Tsunade threw the bottle down and looked at Kai with drunken eyes, "Oh? Didn't you say you're looking for Kakashi first?"

"Kakashi? Is Kakashi also going to strengthen?" Kai widened his eyes.

"No, he should be too different from you," Tsunade said casually and changed the subject. "You can figure it out clearly. Although this kid's chakra may not change your body shape in theory, it is likely that you will turn into a big muscle monster."

Kai was stunned for a moment: "Is it possible that you will not change your body shape?"

He actually had some expectations for himself to become a toned man.

"It will change a little bit, but it's not as exaggerated as before. It's just to verify this conjecture that you were invited over," Ding Ding said, "but it's just a theoretical level and hasn't tried Ninja yet."

"I'm leaving, it's definitely not OK here." Tsunade threw the money on the table and walked towards the hospital with Ding Ding and Akai.

Neither of them was worried about Tsunade's drunken state.

Alcohol cannot bother Tsunade's medical ninjas at the same level. If necessary, all the tricks of extracting a minor problem will be solved.

…………

Under the hospital, the lights of a large treatment room were turned on.

"Here," Kai showed a memory expression, "I remember here, I didn't know that Huoshengji was rescued here."

A semi-permanent technique is drawn on the ground inside the house: the technique of occult hemoplastic yang, which is the effect of stimulating the blood circulation system to remove toxins in the body.

In theory, it can remove any toxins that invade the human body.

However, considering that the toxicity that requires the use of this type of surgery usually cannot support being sent to the hospital, it is the least commonly used surgery among the fourteen large-scale surgery that Konoha Hospital has always prepared.

The most commonly used room is the next door, which can heal large wounds by changing the proportion of media cells. If the ninja at Tsunade is hosted, it can even heal some originally disabled ninjas.

"I will only use part of this technique." Ding Ding's explanation came from the side.

Kai turned his head, and Ding Ding returned to his original body shape at this time. During this period, he used a lot of chakra with Yang attributes, which made his height successfully exceed five meters. In contrast, Kai was as long as Ding Ding's arm.

"Don't worry, even if you grow taller, you will grow at most twenty or thirty centimeters, which is far from me." Ding Ding comforted.

"What do I need to do?" Kai asked seriously.

"No," Ding Ding replied, "You just need to lie in the center of the technique and refine the chakra according to the rhythm."

After a while, Kai took off his vest and belt, and lay in the middle of the room with only a green tights all over his body.

At the same time, two iron frames were erected on Kai's side, and the two chambers of whole parenteral nutritional fluid were directly connected to his venous blood vessels through surgery. In case of expansion of body shape, nutritional supplements were needed. Of course, it is still closed now.

Ding Ding sat cross-legged on the side, pressing her hands together on Kai’s chest: “Teacher Kai, the process may be a little uncomfortable, but you need to stay awake anyway.”

"I understand." Kai signaled Ding Ding to continue.

Ding Ding took a deep breath, and the roar sounded around her, and a huge golden chakra began to gather in her palms and poured into Kai's heart along Ding Ding's palms.

Dong~ Dong--

As the heartbeat, the chakra belonging to Ding Ding instantly pumped to Kai's body, immersed in capillaries, and transported to every cell.

Then, the blood flowed back, and the chakra in the cells were also pulled out. Ding Ding retreated the chakra that was originally poured into the blood and injected it into the heart muscles.

Before the heart beats again, Ding Ding re-drunks the chakra back into the blood...

The biggest disadvantage of Tinding Chakra's enhancement function is the balance problem. That is, the improvement of exercise, endocrine, nerves, etc. will cause other systems in the body to be overwhelmed.

It is no problem to strengthen every part of the human body simultaneously.

But in this case, other problems will inevitably arise.

For example, the strengthening of the nervous system-brain.

The relationship between the brain and human spirit and personality is too mysterious. Even in the ninja world, where black technology is everywhere, it requires extreme caution.

In order to prevent the situation of a sudden change in the ninja's temperament after strengthening, Ding Ding specially found Kai, a fierce man who not only controls his body but also can overtake his will on his body.

But even so, after Ding Ding's chakra entered the brain along the carotid artery, Kai also shocked his whole body and his eyes began to empty...

The purple chakra tentacle immediately shook it out of Ding Ding's head and was linked to Kai's head.

""Keep awake!!"

Kai's eyes immediately became clearer.

"I feel hot now! Youthful ahhhhh!"

Well, it probably didn't go anywhere in Qingming Festival.

"Is this...the eighth door?" Kai murmured. This feeling of "blood boiling" made him quite excited. Subconsciously, he began to pour chakra into the large acupoints in his heart...

"Don't be impulsive!" Ding Ding spoke suddenly, and then quickly explained in the Heart-to-Heart Technique, "The explosion of Qi is not the Eight Gate Desert Armor! I may not be able to save you after you open the Eight Gate!"

"Huh... it seems to cause trouble for you." Kai immediately woke up completely.

"Keep your perception of the body and tell me immediately if you can't hold on!" Ding Ding emphasized.

"I just didn't prepare just now, and this will not happen again." Kai promised.

After that, I really didn't move all the way and didn't say a word. You should know that there was no excessive pain and stimulation throughout the process, but the stimulation and itching of body growth cannot be removed.

Because he deliberately paid attention to not strengthening the myocardium, Kai did not have symptoms of sweat steam or blood steam at this time. It was just that after the blood flow rate reached a certain level, explosive gas began to appear.

During the whole process, Kai's body's strengthening level increased at a constant speed, and all chakra acted directly on the cell level. Although his body size increased, it was still within an acceptable range.

"Nutrition solution." Ding Ding still spoke.

Although the size and number of cells did not increase significantly, the quality increased wildly, and Kai began to tell the feeling of "hunger" everywhere.

When the chakra that exploded inside and out of Kai's body almost turned completely golden, Ding Ding finally withdrew his chakra.

Strengthening, it's over.
