Wu Gengji, I will become Zi Yu's apprentice at the beginning! ! !

Zi Yu showed a satisfied smile on his face. He nodded to Wang Hun and said with a hint of appreciation: "You did an excellent job. Next, I will teach you the art of Qi Refining."

Wang Hun's eyes sparkled with excitement and anticipation, and he replied respectfully, "Yes, Master! I will definitely work harder to learn."

Zi Yu smiled and responded, "Very good, then first, I will explain to you the basic principles of Qi Refining."

Wang Hun listened attentively and asked impatiently, "Master, please explain in detail."

Zi Yu took a deep breath and then slowly said: "The so-called Qi Refining Technique is the skill of humans to manipulate 'Qi'. The user must first have the 'mind's eye' to be able to see the existence of 'Qi' and the trajectory of its flow. By using 'Qi', we can construct objects of various shapes, such as weapons, organs, items, etc. As the ability improves, the constructed objects will become more and more realistic, almost indistinguishable from real objects."

Even though Wang Hun already knew about this, he still couldn't hide his excitement when he heard Zi Yu explain it to him personally.

Zi Yu continued, "When Qi Refining is practiced to the extreme, other elements can even be added to the refined objects. For example, the 'fire' element that burns the divine essence and soul can give objects powerful destructive power; and the 'gold' element that enhances hardness and attack power can make objects indestructible. It's a pity that with my current cultivation, I haven't reached such a peak yet."

Wang Hun showed admiration and praised: "Master, at such a young age, you have already achieved such a high level of attainment. It is already quite remarkable! I believe that it won't be long before Master will reach the pinnacle."

Zi Yu smiled and responded, "Thank you for your encouragement. I appreciate it. Next, I will teach you how to condense and refine Qi." After that, Zi Yu became Wang Hun's mentor and began to teach him the method of refining Qi step by step.

Wang Hun was very focused in his studies, and his talent was extraordinary. With a little guidance from Zi Yu, Wang Hun was able to condense his aura easily. Seeing this, Zi Yu was overjoyed, and even praised him with a little excitement: "Very good! Your talent is really high. Now I will teach you how to condense the entity."

As he spoke, Zi Yu demonstrated how to condense entities. He first condensed a three-inch-long miniature sword, and in a moment, the sword became three feet long, and in the blink of an eye it turned into a three-foot giant sword.

Then, Zi Yu waved his hand and threw the three-meter-long sword out. There was a loud noise, and a huge rock ten meters away shattered.

Then Zi Yu taught: "Stretch out your hand, use your own strength, condense the energy in the palm of your hand, then close your eyes, feel it with your mind's eye, and try to absorb it into your body, so that you and this energy merge with each other."

Wang Hun hummed, and then decisively stretched out his right hand, and a clear golden aura quickly appeared in his palm. As Wang Hun continued to strengthen his control over the aura and deepen his understanding of the aura, the golden aura began to change, gradually forming a sword-like shape.

Then, the illusory sword began to grow slowly, and finally turned into a three-inch-long physical pocket sword. However, this was not the end, the sword continued to grow, and finally turned into a one-foot-long, dagger-like short sword.

Zi Yu was very satisfied with Zi Hun's performance and praised him, "You did a great job, even better than I did back then."

But Wang Hun just smiled and said softly: "Teacher, please take another look."

After hearing this, Zi Yu immediately concentrated and observed more carefully. At this moment, he was surprised to find that the sword in Wang Hun's hand had grown longer under his control, reaching two feet in length, and became more and more real. Then, the sword body grew longer again, becoming a three-foot-long sword, indistinguishable from a real weapon.

Zi Yu, who was always taciturn and serious, was completely shocked at this moment. He showed an expression of disbelief on his face, but more of an extremely excited smile. He said with a slightly trembling voice: "Try to wave it."

Wang Hun reached out and grabbed the sword without hesitation, and then started to dance. Although he did not know any sword skills, this did not affect Zi Yu's excitement at all.

Zi Yu shouted excitedly: "Try to control it and make it fly!"

Wang Hun tightly grasped the hilt of the sword, adjusted his breathing, concentrated his mind, and transferred the energy in his body to the sword. With a low shout, "Rise!" the sword actually slowly rose into the air, flew to a height of ten feet in the air, and began to circle in the air.

Zi Yu then instructed: "Hold the sword tightly and attack the rock over there."

Wang Hun responded, "Okay!" Then, he issued an order, "Come back!" The sword flew back to Wang Hun like an obedient bird. Wang Hun grabbed the hilt of the sword again, and with a determined look, he chopped at a target of the same size as the rock that Zi Yu had just split.

Instantly, there was a loud bang, and the rock instantly split in two, with fragments flying everywhere. Wang Hun was stunned by the power he had displayed, while Zi Yu was ecstatic. They seemed to see a whole new world opening its doors to them.

Zi Yu showed a satisfied look on his face, and quickly condensed a cold and shining Qi-refining sword in his hand. He said to Wang Hun: "Come on, we are going to conduct a real-combat simulation next."

Wang Hun was shocked and waved his hands quickly, saying, "Master, my current strength is far from enough. I can't fight you at all!"

Zi Yu smiled slightly and comforted him softly: "Don't be afraid, this is just a combat simulation. I mainly want to teach you some basic combat skills. Don't be nervous."

Wang Hun heaved a sigh of relief after hearing this and nodded, saying, "So that's how it is. Let's get started." After that, he gripped the sword tightly, his figure flashed, and he attacked Zi Yu like a gust of wind.

Zi Yu held the Qi-refining sword in his hand and calmly went forward to start a combat simulation with Wang Hun. However, this battle was not so much a combat simulation as it was an opportunity for Zi Yu to teach swordsmanship.

In just three hours, Wang Hun showed amazing talent and easily mastered the simple sword techniques taught by Zi Yu. Now he can easily defeat ordinary bandits and even kill them with his sword.

Zi Yu was secretly delighted when he saw Wang Hun's outstanding talent and his ability to learn quickly and comprehensively. He smiled and said, "Okay, that's all for today's class. We'll continue tomorrow."
