With this thought, he directed all his energy to the lower half of his body and held his footing steadily. As time went by, he gradually comprehended some techniques as to how to focus his energy and how to best utilize his strength. Even though the mountain torrent had grown larger and water had risen up to his waist, he was able to hold his own a little easier compared to the previous efforts. A few moments passed and by then water had risen up to his chest and soon up to his mouth.
"Even though I can hold my footing now, I don't think I'll just stand here and get drowned!" he thought. So he leapt back on to the bank.
Who had expected that the Divine Eagle had been waiting for this by the bank? Before his feet touched the ground, the eagle struck out with its wing. Yang Guo hurriedly blocked it using the heavy sword, but the striking force sent Yang Guo right back into the steam. With a splash, he fell back into the water.
When his feet touched the giant rock under the water, his entire body was under the surface. Water had filled his mouth as he was falling. Yang Guo knew that if he had spit the water out of his mouth, then his inner energy would shift upward, thus reducing the strength in his legs, so he held his breath and took a stable stance. A few moments later, he pushed hard with his feet and leapt in the air. A stream of water darted out from his mouth. After taking a quick breath Yang Guo fell back down to the stream bottom. The turbulence and swift currents rumbled past above his head. He simply stayed still like a firm rock in midstream. Gradually his mind calmed down.
"Brother Eagle wanted me to stand in the middle of the mountain torrent, but if I don't hit the rocks in the current, for sure he would belittle me," Yang Guo thought.
He was a man of great pride and was always eager to excel. Even though the eagle was only an animal, he would still rather not lose face in front of it. So when he spotted the branches and rocks brought down by the current, he jabbed and stabbed and tried hard to push them back the way they had come from. In the water, the rocks had become lighter. The heavy sword also felt lighter and easier to control when he waved it around under water. He waved and swung and jabbed and thrust the sword until he was completely exhausted and begun to have a hard time holding his footing. Then he finally leapt back onto the bank.
He was quite afraid that the Divine Eagle would once again force him back into the steam. Without some rest, his tiring legs probably wouldn't be able to stand the forces from the mountain torrent. Not to his surprise, the Divine Eagle didn't want him back on the bank. As soon as it saw him leaping out of the water, the eagle struck out with its wing.
"Brother Eagle," Yang Guo shouted in complaint, "do you know you are killing me right now?"
He jumped back into the creek for a little while but simply could not stand the current any longer and had to leap back to the bank. Seeing the Divine Eagle's wing striking toward him, and not willing to sit down and give in, he had no other choices but to thrust the sword at the Divine Eagle. The two of them soon exchanged three moves, and to his great surprise, the Divine Eagle was forced to take one step back.
"Excuse me!" Yang Guo shouted as he extended his arm and thrust forth the sword again. Sound of whistling echoed as the blade cut through thin air – this was something quite different from his past experience.
Seeing the tip of Yang Guo's sword approaching rapidly toward it, the Divine Eagle no longer dared to take it straight on and had to dodge aside.
Yang Guo knew that the half-day worth of training in the mountain torrents must have improved his strength tremendously. A mixed feeling of shock and joy swarmed in his heart. He couldn't help but question himself, "It should certainly take more than a couple of weeks to increase one's strength and power. How did I gain such great strength after wielding the sword underwater for a mere half-day?" He finally concluded that it had to be the gallbladders from the strange specie of snakes. Those gallbladders must have magical effects for increasing one's power and strength. That was why his strength and inner power had increased tremendously, and he had only noticed it when he released the strength accidentally in dangerous circumstances.
He sat by the creek and meditated for a while. His strength soon replenished. This time he jumped back into the creek for more training without being forced by the Divine Eagle. By the time he leapt back up the bank, the Divine Eagle was no longer waiting by the creek, leaving no clue as to where it had gone.
The rain had begun to slow down. Yang Guo figured that mountain torrents would have to be a lot smaller and weaker the next day. Since he didn't feel that tired, it would be better to train some more right now while the torrent still lasted. At that thought, he jumped back into the creek.
By the time he got back onto the bank the forth time, he found two snake gallbladders placed closed to the bank. Feeling utterly grateful for the Divine Eagle's caring, he ate them and then continued on with his training. Night came, and the mountain torrent had slowly become smaller and weaker.
That night he didn't sleep at all and kept on training in the creek. Gradually he began to realize many sword art principles such as piercing following the force, blocking against the force, slashing from the side, and chopping with a back swing. By then he finally understood: Wielding a sword this way, nothing would be strong enough to stand the force from the sword, and there would be no need for the sword to have a sharp blade. But without such a unique heavy sword, which was twenty or even thirty times heavier than a normal sword, this kind of sword art wouldn't have been effective. If it were just an ordinary blade, the force released from a gentle wrist snap would have shocked the blade into pieces.
The rain finally stopped, and the clear sky shone dimly in dark blue. Moonlight from a new moon illuminated the trees and the water in the creek, painting everything silver. Yang Guo watched the swift currents flushing down the steam path non-stop, his mind as clear as the sky. By then, he understood the principles behind the flow of currents and mastered the techniques with the heavy sword. He knew that he had learned the entire sword art of the heavy sword and there was no more to learn. Even if the Demonic Swordsman could have come back to life, all he could have taught would be the same. From now on as his inner energy grew, he would be able to use lighter swords, and eventually be able to wield a wooden sword like the heavy sword. But that could all be attributed to the advancement of his own abilities and skills. Regarding the sword art, this was as far as it would ever go.
Yang Guo paced back and forth along the bank. Raising his head high, he stared at the bright moon and soon was lost in thought. If Senior Master Dugu hadn't left him this heavy sword, or if there wasn't the Divine Eagle to guide him, and if he didn't eat those strange snakes' gallbladders and thus gain a tremendous amount of inner strength, then the entire world wouldn't have had the luxury of seeing this sword art once again. Dugu Seeking-A-Loss didn't have any help or references yet was able to comprehend such a pinnacle of sword arts all by himself. His cleverness must have been a hundred times better than mine.
