Chapter 12 - Twin-born Martial Souls (IV)

　　Tang Hao's hand casting hammer slightly top, make Tang San back a few steps, at the same time, the hands of the hammer has been turned back, low drink, the body half-turned, feet tightly clasped on the ground, bare in the tattered pants outside the two calves instantly tense, the whole person is like a tiger ready to go, leg force, waist turn back, casting hammer in the invisible has been brought back, dangang bang a loud sound. Heavy landing on top of that piece of red-hot pig iron. 　　Tang San could completely feel that this was just a human body force generation process, Tang Hao did not have internal force, much less any release of martial soul force, this was completely the power of the flesh, while that piece of iron that was red before, was smashed completely collapsed close to one third, the deformation was extremely obvious. 　　"Using the calf to generate power, connecting the power of one's body into a whole, is full power." The hammer in Tang Hao's hand was returned to Tang San, "You do it once." 　　"Good." Tang San had never thought that forging had such a knock. This kind of power generation method wasn't just as simple as using it for forging. It should also be able to be used in one's Tang Sect martial arts. 　　Gripping the hammer handle with both hands, following Tang Hao's previous stance, Tang San's eyes stared tightly at the red-hot iron block, Xuan Tian Gong slowly revolving, going deep into his calves, and his feet clasping tightly on the ground. 　　Tang San shouted, leg strength and Xuan Tian Gong at the same time mana, power erupted from his calves, instantly spreading, his waist turning, driving his back, to his shoulders, and then to his arms. He clearly felt that his power seemed to become unprecedentedly strong, that started from the calf eruption to the end of the arm swinging the hammer, his body seemed to be taken up by this vigorous force. 　　Dang-, the hammer accurately smashed on the iron block with a loud bang. 　　Tang San's entire body because of the hammer's swinging feet off the ground, stumbled forward a step, the hammer rebounded and rose, despite having Xuan Yu hand mutual, there was no problem on his hands, but his arms were shocked by this rebound force a burst of soreness, fortunately Xuan Tian Gong timely operation, this soreness and numbness gradually disappeared. 　　The effect was obvious, even though Tang San had attached Xuan Tian Gong because of his age, the effect of this hammer was not as obvious as Tang Hao's, but compared to his previous hammering, the effect of this hammer was even enough to withstand dozens of previous hammers. 　　Eyeing Tang San's movements, Tang Hao didn't give a comment, but from the hint of surprise that flashed through his eyes, Tang San had obviously done better than he had expected. Tang Hao didn't expect that Tang San would be able to master this kind of power generation in such a short period of time. 　　How could he have known that Tang San had been practicing Tang Sect martial arts diligently, not only did he have the foundation of Xuan Tian Gong, Controlling Crane and Escaping Dragon, Ghost Shadow Misty Tracer plus Xuan Yu Hands, which made his coordination ability far exceed that of his peers. His own enlightenment wasn't bad, so naturally, this technique of power generation was easy to master. Of course, this was the first time after all, and he was not yet pure in his utilization. 　　"Dad, did I do it right?" 　　Tang Hao nodded slowly, "Do you know the role of the heart? The muscle that people use the most is the calf, and the calf is the root of all strength. Utilizing the power of your calves will increase your strength greatly." 　　Saying that, Tang Hao walked to the bellows and sat down, pulling something cast from pig iron from underneath the bellows, it was two pedal-like objects, Tang Hao attached him underneath the bellows, pulling the bellows with both his hands himself, "The role of the bellows is also very important in casting, the metal burns sufficiently for a better forging, because that will make it more resilient. And any piece of metal, even if it is a metal with more impurities, it itself has a soul, once the temperature is not enough, in the forging too much power to make it broken, then, even if re-melted and then forged, this piece of metal is just scrap. Therefore, when you hit the iron with all your strength, you must keep it at a good temperature. Pulling the bellows, similarly using your calves to generate power, not only can you minimize the consumption of power, but also be able to maximize the effect of the bellows." 　　Both feet stomped on those two pedals, sudden force, with the starting point of the legs, the whole body quickly bounced backward, the arms in the natural drive to the handle of the wind box to open, the legs from straightening back to bending, and then send the handle back. Between the back and forth, the bellows was running at full power, Tang Hao's movements didn't look fast, but each stroke caused the bellows' ability to be utilized to the extreme, led by the calf muscles, the body and the bellows formed a special rhythm, the flame suddenly rose from the furnace, and the iron block was instantly burned red. 　　"You pull the bellows, follow the movements I just did." Tang Hao gave his position to Tang San. 　　With the previous experience of swinging the hammer and careful observation, Tang San sat on Tang Hao's previous position and quickly mastered the method of pulling the bellows, although it was still a little bit raw, but with his careful attention, every power shot started from his calf. Sure enough, as Tang Hao said, not only did he save a lot of power, but the effect was also much better than before. 　　Tang Hao took Tang San's casting hammer and said lightly, "Swinging the hammer with all your strength for casting can bring your power into full play, but likewise, when the hammer goes down, the rebound force will also cause a great load on yourself, and if there is no proper way to guide it, not only will you easily hurt yourself, but you will also lose a part of your power and not be able to act on the metal. You have to watch my movements carefully below, this will be the key to whether you can hammer this piece of pig iron to the size of a fist in a short period of time." 　　Taking a deep breath, Tang Hao's eyes became focused, and as Tang San pulled on the bellows, the entire piece of iron had been burned red, blazing flames rising, making the room unusually scorching hot.
