Jumping back onto his feet, Yang Guo picked up the heavy sword and stepped out of the cave for some more rounds of sword training. Having no more fear and worries, even though he still dodged a lot more than blocking, once in a while, he was actually able to organize some sneak attacks in between the fierce and powerful forces created by the Divine Eagle waving of its mighty wings.
This kind of training went on for several days, and gradually, he was able to wield the heavy sword with better control. It almost felt as if the heavy sword was no longer as heavy as the time he first wielded it. In the meantime, he also came to realize that all the sword arts he had learned before were too intricate with too many fancy techniques. He kept thinking about Dugu Seeking-A-Loss's words "heavy sword with blunt edges, simplicity brings superiority" on the slab stone. They had described a realm of sword art much more advanced compared to even the most ingenious sword techniques in the world. While sparring with the Divine Eagle, he concentrated on comprehending the movement of his sword, and what he started to realize was that the more ordinary a sword move is, the more difficult it was for an opponent to defend against it. For example, if he simply thrust out straight forward, as long as he had fierce and resourceful power to back it, the might of the thrust would be actually more powerful than the kind of sword arts like the "Jade Maiden Sword Art" that relied on fluctuating and unpredictable techniques. Even though he only had one arm, and after eating those snake gallbladders the Divine Eagle had brought to him, his arm had become much stronger than before.
One day while strolling about the valley, he discovered the bodies of three giant poisonous snakes on the ground. Their bellies had been ripped open and cuts from sharp talons left snake blood all over their bodies. By then, he was sure that the bitter things he had been eating were snake gallbladders. The bodies of these poisonous snakes shinned in a vaguely golden color. He had never seen any snakes like these before and had no idea what kind of snakes they were.
"I suppose the reason why the Divine Eagle has such tremendous strength is because it had eaten a lot of gallbladders of this strange species of snakes," he thought to himself.
After over months worth of sparring, with some hard effort, Yang Guo could actually take on the Divine Eagle's mighty force head to head now. Each of his thrusts had also become so powerful that they would whistle in the air. He couldn't help but feel very satisfied with himself. Since his skills in martial arts had advanced to a new level, the martial arts he learned before all seemed to be so insignificant. It was just like once one climbs to the top of Mount Tai, the whole world looked small and insignificant. But in another thought, he realized that without his previous foundation in martial arts training, he wouldn't have been able to advance to such a new level. After all, the Divine Eagle was just an animal that couldn't speak. It might be able to guide some, but it would never be able to explain things or provide advice. Besides, the Divine Eagle didn't really know any true martial arts skills. All it had was the god-given mighty strength plus the handful of moving and dodging techniques it had picked up while sparring with Dugu Seeking-A-Loss in the many years of companionship.
One morning, after Yang Guo got up, he found heavy rain pouring down from the dark cloud covered sky. "Brother Eagle, it's raining very hard. Are we still going to train today?" he asked the Divine Eagle. The eagle held Yang Guo's sleeve in its beak and pulled him toward the northeast. Then it let go of the sleeve and strode out. "Is there something strange again in the northeast?" Yang Guo thought aloud. He grabbed the heavy sword and then followed in the rain.
A couple of miles into the journey, some vague but continuous rumbling sound came to Yang Guo's attention. And the further they walked, the louder the rumbling sound became. It was the sound of a waterfall.
"With such a pouring rain, I'd better watch out for mountain torrents," Yang Guo reminded himself.
After turning round a mountain gorge the sound of the waterfall suddenly became so much louder; it could almost deafen one's hearing. Between two peaks, the waterfall crashed down and poured into the creek below like a white dragon. With thunderous echoes, the swift currents rushed downward with mighty force. The many broken branches and rocks, carried by the currents, only took a split second to be flushed down the stream.
By then, the rain had become even heavier and Yang Guo had become soaking wet. A thin mist from the smashing waterfall surrounded everything, creating a magnificent view. But seeing the mighty force from the mountain torrent, Yang Guo couldn't help but feel a slight dread inside of him.
Holding Yang Guo's sleeve in its beak, the Divine Eagle dragged him toward the creek as if it wanted Yang Guo to jump in.
"Why do you want me to go down there? The stream is running very swiftly. I am afraid that I won't be able to hold myself steady," Yang Guo asked in surprise.
The Divine Eagle let go of Yang Guo's sleeve, and after a long and loud roar, it jumped into the creek and landed steadily on a huge rock in the middle of the creek. The eagle swung its left wing forward. A rock that had been carried down by the rushing current was sent back up the stream by the swing. As soon as the rock came back down with the current again, it swung its wing once again, and sent the rock flying up the stream a second time. The eagle did the same thing five or six more times, and the rock never made it past the eagle. By the seventh time, the Divine Eagle gave it a good smack, which sent the rock flying out of the water and it landed on the bank. The Divine Eagle then leaped back onto the bank and stood next to Yang Guo.
Yang Guo understood. Demonic Swordsman Dugu Seeking-A-Loss must have come here often to train sword arts in the mountain torrent every time it rained. But he knew very well that he didn't yet possess such skills and strength. Feeling afraid, he hesitated.
Suddenly, the Divine Eagle extended its wing out and pushed Yang Guo on the arm. Since it was standing so close to Yang Guo, and the push caught Yang Guo by surprise, he lost his footing and fell into the stream.
In the rush, Yang Guo quickly used a technique called the "Thousand Pound Plummet" and landed on that huge rock the Divine Eagle had stood on. As soon as his feet entered the water, the great force from the swift current almost swept him off his feet. Yang Guo stumbled back and forth and had a hard time maintaining his balance.
"Senior Master Dugu is a human, I am also a human. If he could hold himself steady, why can't I?" Yang Guo thought to himself. So he took a deep breath and then concentrated all his attention on the effort to fight the force of the swift currents. That alone had exhausted all his strength. It was simply impossible for him to spare any strength to hit the rocks in the current with the heavy sword.
In the amount of time it took to burn a joss stick, Yang Guo had exhausted all his strength, so he jabbed his sword on the rock, and with a push, leaped back on to the bank. Before he even had a moment to catch his breath, the Divine Eagle had already swung its wing toward him once again. Having being on his guard, he dodged the push swiftly. Quickly taking in a few deep breaths, he jumped back down into the creek himself, thinking, "This Eagle Brother is indeed a strict teacher and a forthcoming friend. He wouldn't cut me any slack in the training. He certainly has high expectations, and I, of course, want good improvement."
