Renewal Taekwondo may be strongest martial art which can make humans to be par with god but it contains weakness. And not one but three weakness.

First, is that it have limited points to attack. Renewal Taekwondo have limited points to attack in opponent side. All the attack moves are powerful but they are focused to a particular region.

Second, is that it is weak in close combat. Most moves of Re Taekwondo are fixed. Re Taekwondo is martial art that uses the power of rotation to power up the kicks to create inhuman power from kicks. And by coming closer can restrict the movement of user and without rotation the moves are not powerful it should be. A capable martial artist can take a beating in close combat easily.

Third, is that it creates to much burden in human body. Every move should be perfect to create heavy power. A kick can give high wind pressure. And to use this type of move creates high burden in body.

And the way to remove the weakness is easy. First and second weakness can be removed by mastering several other martial arts. And Alex who have learned full contact Karate is perfect as replacement. It is powerful in close combat and with this he can switch the martial art in middle of battle to confuse the enemy who predicted the attack points of Re Taekwondo.

Third weakness can only be removed by practice. The body have to get used to Re Taekwondo. It may not completely remove the burden but should decrease the burden in human body.

And that's why Alex thought of practicing both Re Taekwondo and Full contact Karate to made his body to be perfect for both martial arts. If the opponent is a bit long ranged then use Re Taekwondo and if intents to use close combat then use Full contact Karate to counter.

Alex started to train in a place near the cave to train his arts. First he intents to perfect his karate. Alex's karate profiency is A. To explain he has perfectly completed the basics. Now what he has to complete is the dance of four gods. This is combination of four moves which can be regarded as finisher move. Any normal martial artist is confirmed to go down with this combination of moves. First it interrupts the opponent's offense, then offsets the balance, and then breaks the defence of the opponent. And this is partially right. These three moves are actually used to create a huge wind pressure around user, which can be controlled by user to give opponent a huge wind blast.

<< 1st Stance : Basaltic Fist >>

Alex tries to use the first stance to throw a fist towards the tree. But it looks harder than normal. But Alex without any time to feel down tries to do again. He is determined to complete the Full contact Karate.

After half a month....

Alex was standing wearing a white yukata which is the training uniform for karate. And after two months of hardcore training he intends to use the dance of four gods.

<< 1st Stance : Basaltic Fist >>

Alex throws a powerful punch which makes shockwaves travel throw it. Then to continue the continuation of moves he uses the next move to keep rhythm.

<< 2nd Stance : Pheonix Kick >>

He stomps the ground with a huge amount of force which makes a huge shockwave travels through ground.

<< 3rd Stance : White Tiger's Dance >>

Then Alex releases a combo of punches and kicks. It can be seen as a barrage of punches and kicks.

And finally an air flow is being made around Alex. Alex took control of it.

<< 4th Stance : Blue Dragon's Storm >>

And then he released the wind blast.

*Boom!* A whole piece of land in front of Alex disappeared!! Just by using pure martial arts a piece of land just disappeared like nothing!! Even Alex was shocked. In Dragon Ball this type of attack is easy but with the usage of Chi. They use Chi to produce destructive power. But what Alex used was not a type of energy. It was created by just punches and kicks.

[ Full contact Karate rank up!! ]

[ Full contact Karate ( A →S) ]

Alex was fully excited to see the power of karate. Now he can't just wait to see power of Re Taekwondo.

"But the Karate only increased till S rank. It should be increased to Ex rank. It still has something left. I will find about it during my travels."

Alex said as he changed his dress which he dress set he bought from system. The place where he was training was already in ruin. He thought it would be better to search a new and big place for his another martial art.

After a few days of rest and travel he found a new place in forest outskirts which seemed to be connected to a desert. It seemed to perfect place to practice his new martial arts.

Every time he came to practice to desert and used sleep in forest in night. Most of Re Taekwondo is made up of powerful kicks generated from the rotation of the body. And most of the kicks are for the upper part of the body.

After another 2 months passed.... Alex has completed all basics and moves of Re Taekwondo. Only he needs grab the recoilless form and them splitting a sky is a not dream.

[ Renewal Taekwondo rank up!! ]

[ Renewal Taekwondo ( F →S )]

He leaves the outskirts and goes deeper of the forest. While the desert where he was training was full of deep ravines which were made from his pure kicks and air pressure.

" I have learned and ranked my martial arts to the limits of my body. My strength have increased and my dexterity as well. Now my control of my body is very good. But this is not the realm of martial arts. Or else the system would already notified me. Now, the only way is to learn to apply in actual combat. I have to search opponents." Alex made up his mind to find some opponents to integrate his techniques to body so that he can use them easily and casually.

But a normal martial artist would do no good in his practice and he also doesn't want to search for opponent flying all over the earth. A powerful martial artist and powerful one, Alex found one. He quickly flew towards the direction where he could find the opponent. And after 5 minutes he found the one he was looking for near the river.

An old man who is short, stubby old man with small dark eyes and a bushy white mustache and eyebrows and is also bald. He wears a Chinese martial arts uniform, which consists of a sleeveless orange jacket over a long sleeved black shirt, and wears a green hat.

Yes, the old man is current generation's best martial artist Son Gohan - Grandpa of Son Goku.
