Lu Yu obviously didn't feel the prohibition that Luo Qi had imposed on him. When he entered the river, he began to keep his mouth shut, not daring to speak.

Luo Qi turned his head to Lu Yu and said, "Xiao Xi, I have imposed a ban on you, you can open your mouth to speak, and you won't get into the water." ”

Lu Yu covered his mouth with his hand and slowly opened his mouth until he realized that it really wouldn't enter the water, then he let go of his hand and said, "It's amazing, master, I also want to learn this kind of prohibition." ”

Luo Qi said: "In the future, I will teach you step by step. ”

"That's right, Master." Lu Yu immediately asked, "Why is the aura in my body now pure and turbid?" ”

"That's because you haven't refined your turbid aura to perfection yet. The last time I visited you, you had learned to capture and collect aura, but you didn't know much about the refining after collecting. I only know how to compress the aura into the aura solid yuan pill. This doesn't work for cloudy aura. You can find the answer if you go back and carefully read the second half of the Introductory Chapter on the Law of Reiki Cultivation. The purification of aura is like the process of removing the root and preserving the truth, which requires a lot of strong internal strength to complete. After Luo Qi finished speaking, he took Lu Yu's right hand and flew down to the bottom of the river.

There are many smaller fjordmons floating in the river, and at the bottom of the river, the number of fjordmon gradually decreases, and the water becomes clearer.

Finally, the master and apprentice reached the bottom of the riverbed.

The riverbed is paved with sand and gravel, and it is empty, with only a few aquatic weeds stranded at the bottom of the river.

Not far away, a stone castle-like building complex came into Lu Yu's eyes.

The huge stone castle is particularly vast at the bottom of the river, and you can occasionally see guests in the doors and windows of the stone castle.

Lu Yu found that the front gate of the stone castle was open, so he said, "Master, can we go in directly?" ”

Luo Qi smiled and said, "Yes, Lu Xi, this stone castle is Baoyuxing. Let's go in together. ”

Lu Yu walked quickly into the stone castle, and Luo Qi followed behind him.

As soon as Lu Yu entered the stone castle, he was deeply shocked by the various immortal artifacts hanging on the walls in front of him.

The immortal weapons here are different, some are like a broadsword, some are like a sword, and some are like a pair of wheels, a shield, a spear, etc., and it seems that there are many weapons.

Lu Yu stared at one of the azure swords and said, "Master, I want this sword." It looks very beautiful, it has a sharp shape, it is very intimidating, and it looks like it can be used as a flying sword, allowing me to soar through the clouds. What I want most now is an immortal weapon that will allow me to fly. Master, isn't this sword very expensive? Can we afford it? Lu Yu said excitedly.

Luo Qi saw that he wanted this sword very much, so he directly asked the white-clothed staff next to him, "Is this blue sword still on sale?" ”

The staff member dressed in white on the side said: "No one has decided on this item yet, and it can be sold." ”

Luo Qi asked bluntly, "So how much does this sword cost?" ”

The white-clothed staff reported: "Four hundred thousand cents." ”

When Lu Yu heard this, he said in surprise: "400,000, so expensive!" ”

The white-clothed staff continued: "This kind of high-grade immortal artifact is priceless, and you are lucky to be able to buy it." ”

Luo Qi immediately conjured a large bag of silver glittering rectangular immortal coins from his hand, handed it directly to the staff member, and said, "We want this azure sword." Please wrap it up in a moment and let us take it away. ”

Lu Yu also knew that he should be low-key when doing things outside, so he was secretly proud in his heart: "My father is really generous to me, and I feel a strong father's love." I took a fancy to such an expensive sword, and my father said he would buy it without thinking about it. To be honest, isn't my father encouraging me to cultivate hard by doing this? Yes, I have to work harder. ”
