Chapter 143: The moment of boiling

"You'll know when you practice!" Song Hetong smiled mysteriously, then took out a few pieces of black raw materials and threw them into the cauldron. Under the raging flames raised by Tang Ao, they quickly became red.
"Huh huh!"
In the hut, Tang Ao squatted under a blast furnace with a height of more than one person, dragging a box-like bellows, and constantly ventilating the furnace.
The carbon stone in the furnace had already been burned like the noon sun, shimmering with orange light, the tongue of the fire was straight up, and the hot outer flames licked the bottom of the crucible from time to time.
In the pot, a few large pieces of black material gradually burned red, and the outer layer even showed signs of softening and liquefaction.
"Boy, yes! Burning Zhenyue Black Stone so quickly, it seems that you are really a piece of iron." Song Hetong's vigorous voice echoed in the hut, and he reached out and touched a few black stones to join the cauldron.
"There are ten baskets of black stones here, and the bow tire used to refine the sun-shooting divine bow is the Zhenyue Wujin extracted from these ten black stones, and only it can withstand the tremendous power of the sun-shooting divine arrow when it bursts out."
"So you guys just pull it slowly, this stuff can't finish a basket in seven or eight hours."
"Puff!" Tang Ao almost squirted out a mouthful of old blood, cooperating with the coolies he had been dragged to do for so long.
Complaining and complaining, after Song Hetong's preaching, Tang Ao looked forward to the sun-shooting bow after training, and immediately pulled up the bellows, hoping to melt the black stone soon.
After pulling for more than an hour, Tang Ao's arms gradually became soft and numb, and his muscles swelled and became sore. Can't help but ask, "How is it, is it melted?"
"What's the impatient? Only half a basket of black stones, the black stones in the pot haven't melted yet? Why, do you feel that your arm is sore, and you can't get it?" Song Hetong asked with a smile.
Tang Ao smiled bitterly, "You want to say that it broke out in an instant, my power is 100,000 jin, but I pull it slowly, I really..." After a long time of brewing, Tang Ao couldn't tell the feeling.
"Try to follow the rhythm of pulling the bellows with each breath and breath, pull it and breathe, push back and breathe out." Song Hetong induced Tang Ao bit by bit.
"Pull, suck, push back, and breathe out." Tang Ao muttered the trick silently, and did dozens of back and forth regularly, and he clearly felt a warm current rising from his dantian, circling around his body, and finally gathered. The position of the arm, the originally sore arm gradually became more comfortable.
"It's really possible! Is this the power of the inner alchemy used?" While enjoying the comfort brought by the operation, Tang Ao curiously asked Song Hetong's principles.
"You monks, especially young people, always want to defeat each other in the duel, so you use your vitality. In the end, the true essence is exhausted and the painful pain is like traveling through the eighteenth hell." Song Hetong sighed. Tao.
"In fact, as long as you act naturally and do whatever you want, can you reduce the waste of vitality and maximize the use of vitality. This is also an experience I have forged for many years."
"You continue to pull it down, I have others to teach you." Song Hetong poured all the first basket of black stones into the cauldron, "Hurry up, increase the heat!"
With an order, Tang Ao followed Professor Song Hetong's method of luck, pulling and pushing, breathing in and out. Tang Ao only felt that his body was getting dry and hot, coupled with the scorching of the stove, his throat seemed to be scorching, dry and smoke; his body was sweating profusely, and the sweat beaded down into a stream of water, and it was scalded as soon as it hit the ground. The place has evaporated.
"Now you go and call your vitality with the rhythm of exhaling and inhaling, and simply feel it. This basket is about to melt, you have to be prepared.
When I say yes, you remember the temperature in the cauldron and the state of the flame. The next step is to maintain that state until Zhenyue Wujin precipitates out. "Song Hetong stared at the changes in the crucible intently, and told Tang Ao the main points of tempering for a while.
"Yes!" Tang Ao moved his thoughts, eliciting two ribbon-like vitality from a big hole in the back that emits a faint fluorescent light, and gathered on his arm to relieve fatigue and prepare for the heavy load for a while.
At the same time, the "Tianmu Jue" was lucky, and his eyes were covered with a layer of golden light, everything in front of him was gathered in his mind, and even the trajectory of the flame was clear.
"Trying to grasp it by feeling, and then running the "Tianmu Jue" will give you a better experience. Those subtle movements can be clearly revealed." Song Hetong carefully enlightened Tang Ao from the side.
Tang Ao nodded, closed his eyes, maximized the sensory world around him, and experienced it with all his heart.
"Papa!" It was the sound of dripping sweat!
"Zzizi!" The flame in the blast furnace scorched the cauldron.
"Huh?" Flame? Yes, it is a flame, swinging back and forth to disturb the air, making a sound like there is or nothing, scratching the bottom of the cauldron like fluff.
Tang Ao showed a smile of joy. He used to look at the world with his eyes, but he didn't expect to experience a different taste with his senses.
Tang Ao felt the fun of the so-called "food marrow knowing taste" and couldn't stop at all. The whole body explored wantonly, and felt this little hut clearly.
"Okay! Okay! Hurry up, the black stone has melted, you are ready." Song Hetong coughed and reminded Tang Ao.
At this time, the black stones in the pot have melted, and a sticky pile of them is in the pot, occasionally some small bubbles come up in pieces. Obviously it had reached the moment of tumbling as Song Hetong said.
At this moment, apart from the crackling flames in the blast furnace, and the dragging sound of the bellows, both of them stared at the blast furnace intently. While Tang Ao breathed in, pushed and pulled, listening to Song Hetong's signal all the time, the hotness and burning degree of the flame in the boiler were all painted in his mind.
Song Hetong's white eyebrows were tightly furrowed, and although he was old, he still stared at the crucible with more and more dense bubbles.
It is like a jackal on the grassland, lying prone on the side, waiting for a fat sheep to die step by step. Every time a little bit of time passed, the nerves of the two were highly concentrated, waiting for the moment of release.
"it is good!"
With a sudden order, Tang Ao's eyes flashed with two brilliant lights, and the pulling speed of his arms became one after another, fast and slow; in his mind, at the moment Song Hetong applauded, he outlined the appearance of the burning of carbon fire, and the body feels The temperature at that instant was recorded.
"Hold it, Zhenyue Wujin is separating."
Tang Ao didn't dare to be careless, and tried his best to control the heat of the boiler, and at the same time, his vitality kept on his arms to relieve the soreness. Despite this, Tang Ao's arms couldn't help trembling, obviously already reaching the limit.
