It has been three days since Zhishu and Tiantian once again promised to recuperate well in the future, but Zhishu is still exercising with sweat.

In fact, in this forest, there are three wisdom trees working with different postures at the same time.

Zhishujia is immersed in the sea of books. From time to time, the eyebrows are slightly wrinkled, and from time to time, there is a happy face. Really a nerd. The green chakra light in his hand from time to time made him a little different.

Zhi Shuyi sat where he was and didn\'t move at all. It seems to be sensing something, and it seems to be sleeping. The face is incomparably quiet, like an ancient Buddha.

Actually, he\'s sensing nature, chakra. Originally, Zhishu arranged his shadow body to practice ninja. However, because the shadow body is completely copied from him, once you use ninja, your shadow body context will be unbearable and scattered.

Finally, it can only be assigned by the wisdom tree to the inductive nature chakra, which is almost impossible to succeed.

The wisdom tree itself kept pouring its fist into the stone. It\'s just some bandages on your hands.

With the sound of banging, the bandage on Zhishu\'s hand gradually exuded blood.

In fact, this is already a very common thing for Zhishu. Even now he has adapted to the pain.

So that he had another standard to measure his exercise, when to soak all the bandages with blood, and when to end the hitting training.

Bang!!!

With Zhishu\'s last punch, the big stone broke. Zhishu looked at his already miserable hands and said with emotion, "fortunately, he is a whirlpool family, otherwise I\'m afraid he can\'t deal with such a wound with his own medical ninja."

Then a green light rose on the right hand of the wisdom tree. Press on the back of your left hand. Originally, the wound was just some skin trauma, which recovered more quickly under the action of medical ninja.

Then Zhishu used the same method to deal with his right hand.

After all this, Zhishu untied the art of shadow separation.

The shadow part of learning medical Ninja brought him a lot of basic knowledge of medical ninja.

But it is impossible to deal with the disease of paralysis quickly.

This is not only the problem of medical ninja, but also the problem of studying a new medical method.

Otherwise, Zhishu will go directly to Muye hospital and find the top doctor for treatment?

And Zhishu can vaguely notice that, including sister qiannai, is also learning medical knowledge about leg paralysis. She is also making some efforts to cure her right leg.

Of course, if you do some massage every day as it is now. For more than half a year, the paralysis of his legs will naturally improve. But Zhishu really doesn\'t want to waste so much time.

As for the shadow part of chakra who perceives nature, there is no gain at all.

It\'s like sitting there all morning. Zhishu, who cherishes time so much, has felt heartache.

With the school time approaching, Zhishu feels more and more powerless.

The leg injury still showed no signs of improvement, and lost the advantage of body surgery. You can\'t use the Ninja that consumes a little more chakra.

After rowing like this, Zhishu felt that he might really lose to riqingmu.

"No, I must develop new skills."

Zhishu clenched his fist, as if this was his only route.

Even if your injury is not good, as long as you can develop a technique that can be used in this state. It is also a victory.

And with previous experience in developing new technologies, perhaps this route is easier for Zhishu.

But what kind of new technology should I develop?

Zhishu fell into his own thinking.

First, this technique can\'t consume too much chakra. Even the chakra consumption of ordinary d-level Ninja can\'t exceed.

Unless it is a ninja that has little to do with the context like shadow separation. Otherwise, even the art of Hao fireball is enough for Zhishu to drink a pot by himself.

Secondly, the power of this Ninja cannot be too low. Otherwise, it will be meaningless to develop new technology by yourself. Using Ninja is not as powerful as your own fist. It\'s better to use your own fist.

Third, this Ninja is best to help yourself move, or to improve your attack distance. This is the biggest short board of Zhishu now. Lost a leg, even if he can barely escape several attacks by strength and jumping.

But it doesn\'t play any role in real combat. It\'s the same thing to die early and late.

With these three limitations, Zhishu began to think further about how to achieve it.

Generally speaking, the chakra scalpel, which has been changed a lot by him, is the most suitable.

First, because of experience, but the power of chakra scalpel can also meet the requirements.

However, this Ninja actually consumes a lot of chakra.

And other ninja, Zhishu has less ideas. The skill of Hao fireball is weakened again, and his current context can\'t afford it.

And a series of lamp array, Zhishu hasn\'t been used since iluka got this bound ninja.

Even Zhishu felt that his excitement when he got this Ninja was wrong?

Then, there are only three body skills left.

"Is there really no way?"

Zhishu fumbled his chin and racked his brains.

"Zhishu, what are you thinking?" A crisp voice interrupted Zhishu\'s thinking.

What comes into view is the figure carrying a lunch box every day.

I can\'t help but feel a little warm in my heart.

After receiving the meal from Tiantian, Zhishu ate it. He also spoke out his confusion without reservation.

He didn\'t expect to give any good advice every day.

But I listen very carefully every day, with big eyes blinking.

"Zhishu, you mean you want to develop a ninja that consumes less chakra, but the consumption of chakra scalpel you are most familiar with is too high?"

"Well, that\'s right." While eating delicious food, Zhishu muttered.

"I remember the uncle of the tolerance store once said that the metal that can circulate chakra is too expensive. Therefore, swords made of this metal often adopt hollow design. This can not only reduce the power, but also greatly save the cost. Can your chakra scalpel do this? "

At first, Zhishu didn\'t intend to seriously listen to Tiantian\'s suggestions, but just gossip.

But I didn\'t expect that every day really gave him a very good idea.

Before, due to the huge chakra, I often condensed into chakra scalpel regardless of the large amount consumed by chakra.

And now if we say that every extra chakra on the chakra scalpel is saved?

Can you reuse your most familiar ninja?!
