Tang Hao's hammer in his hand slightly tapped, causing Tang San to retreat a few steps. At the same time, the hammer in his hand had already turned back, and with a low growl, his body half-turned, his feet tightly gripping the ground, the two small legs exposed outside the tattered pant legs instantly tensed up, the whole person was like a tiger waiting to pounce, his legs exerting force, his waist turning back, the hammer had already brought back in an invisible manner, and with a loud crash.

  Heavily fell on that piece of red-hot pig iron.

  Tang San could completely feel that this was just a process of human physical strength, Tang Hao didn't have any internal energy, nor did he release any martial soul power. This was purely **'s power. And the iron block that had been bright red earlier was smashed to the point where nearly one-third of it had collapsed and deformed extremely obviously.

  "Using your calf muscles, connect the power of your entire body into one entity, that's what it means to use your full strength." Tang Hao handed the iron hammer back to Tang San, "Your turn."

  "Good." Tang San had never thought that forging would have such a knock on the door. This method of exerting force was not just used in forging, it seemed. It should also be usable in his own Tang Sect martial arts.

  With both hands grasping the hammer handle, he learned from Tang Hao's previous posture. Tang San's eyes stared tightly at the red-hot iron block, his Xuan Tian skill slowly circulating, penetrating deep into his calves, and his feet tightly locked onto the ground.

  Tang San let out a loud shout, his leg strength and Xuan Tian's power simultaneously bursting forth. The force exploded from his calf, instantly spreading to his waist, which rotated, bringing his back into motion, then his shoulders, and finally his arms. He clearly felt that his strength seemed to have become unprecedentedly powerful, as if his body was about to be lifted off the ground by this surge of energy, starting from the explosion in his calf to the swing of his hammer-wielding arm.

  When it did, the iron hammer struck the anvil with a loud clang.

  Tang San's entire body was lifted off the ground by the swing of his hammer, and he took a step forward. The hammer rebounded back up, and although the Jade Hand protected him, his arms still felt a stinging numbness from the recoil. Fortunately, the Heaven and Earth Furnace rotated in time, and this numbing sensation gradually dissipated.

  The effect was evident, although Tang San's age made the added Xuan Tian Gong less effective than Tang Hao's, but compared to his previous strikes, this one had an impact that could withstand dozens of previous ones.

  Watching Tang San's movements, Tang Hao didn't give any evaluation, but from the surprise that flashed in his eyes, it was clear that Tang San had done much better than he had expected. Tang Hao hadn't thought that Tang San would be able to master this method of exerting force in such a short period of time.

  He didn't know that Tang San had been diligently practicing the Tang Sect's martial arts, not only did he have a foundation in Xuan Tian Wu Shang, but his coordination ability far surpassed that of his peers with Kontakei and Ghost Shadow combined with Xuan Yu Shou. His own comprehension wasn't bad either, so naturally, this technique was easily grasped. Of course, after all, it was the first time he used it, and it wasn't yet pure and proficient.

  "Dad, am I doing it right?"

  Tang Hao nodded slowly, "Do you know the function of the heart? The muscle that people use most is the calf. The calf is the root of all strength. Using the power of the calf well will greatly increase your energy."

  As he spoke, Tang Hao walked over to the bellows and sat down beside it, pulling out a pair of iron pedals from underneath. He connected them to the bottom of the bellows and grasped the bellows with both hands. "In casting, the role of the bellows is also very important. The metal burns fully, allowing for better forging, which makes its toughness stronger. Any piece of metal, no matter how many impurities it has, has a soul of its own. If the temperature is not enough and the force is too great during forging, causing it to break apart, then even if you re-melt and re-forge it, that piece of metal will only be scrap. So when you strike the iron block with all your might, you must keep its temperature just right. Pumping the bellows also uses leg strength, not only can it minimize energy consumption as much as possible but also make the effect of the bellows reach its maximum."

  His feet stepped on the two pedals, and with a sudden burst of force, his legs lifted off the ground, propelling his entire body backward. His arms naturally swung back, opening the bellows' handle, before returning to their original position. With each repetition, the bellows operated at full capacity. Tang Hao's movements didn't seem fast, but every motion brought out the maximum potential of the bellows. Under the guidance of his calf muscles, his body and the bellows formed a unique rhythm. Flames suddenly shot up from the furnace, and the iron block was instantly heated to a bright red color.

  "You come and pull the wind box, according to my previous action." Tang Hao gave his position to Tang San.

  With the experience of wielding a hammer previously and careful observation, Tang San quickly grasped the method of pulling the bellows from the position in front of Tang Hao. Although it was still a bit awkward, under his careful attention, every effort started from his calves. Indeed, as Tang Hao had said, not only did he save a lot of strength, but the effect was also much better than before.

  Tang Hao held Tang San's forging hammer and said calmly, "Using full force to swing the hammer for forging can bring out one's strength fully, but at the same time, the recoil force will also put a great burden on oneself. If there is no suitable method to guide it, not only will it be easy to hurt oneself, but also cause some of the power to be lost and unable to act on the metal. You must watch my movements carefully below, this will be the key to whether you can hammer this piece of raw iron into fist size in a short time."

  Taking a deep breath, Tang Hao's eyes became focused, and with Tang San's pull on the bellows, the entire iron block had been heated to a bright red, with scorching flames rising, making the room abnormally hot.
