Qiu Lin picked up Lu Xi's left hand and gently flicked the silver dragon ring on Lu Xi's middle finger with his fingers. Only then did Lu Yu realize that the Silver Dragon Ring was shuttling through this time and space with them.

As the Silver Dragon Ring slowly turned, Lu Yu felt a dizziness in front of him, and he came to a new space.

It's one hell of a space. The ground is full of volcanoes and lava, and the surface temperature seems to be very high. The lava flowed slowly, emitting red flames and orange-yellow sulfur foam.

"Where is this? Senior Brother Qiu Lin, I feel that it is very dangerous here, the temperature is very high, but I don't feel hot. What is the reason for this? Lu Yu felt that there was fire all around him, and he and Senior Brother Qiu Lin were suspended in the air, looking down at a large group of volcanoes on the ground, but he felt that he was not burned. On the contrary, his body was as cold and airy as usual.

Qiu Lin immediately explained: "Senior Brother Lu Xian, that's because you are now a primordial immortal. The body of the first immortal can't feel the temperature change, and Master Luo Qi should have told you about this a long time ago. Didn't you feel very hot when you were in the medicated bath? ”

"yes." Lu Yu suddenly realized and said, "Yes, when I was taking a medicinal bath, I really used boiling water at 100 degrees Celsius. When I soaked in, I didn't feel the burning. So, Senior Brother Qiu Lin, if my feet stand on the lava on this ground, won't they be burned? ”

"Yes, your reasoning skills are good." Qiu Lin said.

"Shall we go down and walk on it, then?" Lu Yu asked.

"No, because you're still wearing shoes and clothes. The clothes on your body are not limited by temperature like your body. You stand up and your shoes burn out immediately. Qiu Lin said, he tore a ribbon from his arm and threw it down.

As soon as the ribbon touched the hot lava on the ground, it immediately burned into a wisp of green smoke.

"That's right." Lu Yu nodded and said, "It's no wonder that Master Zun doesn't let me go out of the sect at will." I look like I'm in danger. ”

"Yes, Lu Xi. The master is all for your good. I'm bringing you out now because I'm by your side to protect you. Rest assured, you're making rapid progress now. Any immortal is from ignorance to omnipotence. Knowledge and experience are accumulated little by little, and you don't need to rush. Qiu Lin said, and flew to a higher altitude with Lu Yu. Lu Yu can see the whole picture of the ground now.

It turned out to be a cliff. In the distance, in addition to these volcanic lavas, there are many towering mountains.

Lu Yu said, "Senior brother, what kind of space is this?" ”

Qiu Lin said: "This is a plane. ”

"What is a plane?" Lu Yu asked.

"A plane is a form of existence in space. A bit is the location, and a surface is the area and size of the space it covers. Qiu Lin patiently explained, scanning this mountain range with his divine sense, and then said: "The plane we came here is not large, it is mainly a suspended continent. This continent is mainly made up of mountains, with volcanoes, icebergs, jungle mountains, rocky mountains, mud mountains, and other types of mountains. This plane is primarily a block-shaped group of mountains. I've just scanned it with my sense, and there are no living forms here, and there are no resources to dig into. ”

Lu Yu looked at the magma rolling underground, and said, "Then let's leave this plane." Since it's of little value, I think we'd better look at it in another plane. ”

"Okay, Lu Xi, let's go. The spaces I'm showing you now are all the ones I randomly selected with the Silver Dragon Ring. ”

Qiu Lin paused, and then said, "Do you have any space you want to go to?" As I can describe, I can use the Silver Dragon Ring to teleport us exactly where you want us to go. ”

Lu Yu said: "I want to go to the resource-rich plane, anything goes. ”

"You kid still has a strong thirst for resources. Since you don't want to see the scenery in vain, let's go to a resource-rich plane and have a look. After reading it, let's go back to the Zen Yun dormitory. It's been a long time since we've been here, and it's been an hour or two outside. Qiu Lin said, picked up Lu Xi's left hand and turned the silver dragon ring.

Lu Yu suddenly felt a burst of golden light appear in front of him. He fixed his eyes and saw that he and Qiu Lin had come to a new space, which was full of sparkling constellations, very dense, but it didn't look like a universe. Because those asterisms were very large and very close to him, there were no celestial bodies such as nebulae and galaxies around him.

Qiu Lin looked at the glowing body and said, "Lu Xi, we are lucky to have come to a plane rich in resources. All of these glowing stars are useful minerals. You can make a mark here and come back to mine some minerals often in the future. ”

"What, we can still leave a mark in the space?" Lu Yu said in surprise, and couldn't help but turn his head to look at Qiu Lin.

Qiu Lin said: "Of course you can make a mark, otherwise how do you know which spaces you have been to?" Qiu Lin stretched out his left index finger and pointed upward, and a circle that emitted red light immediately emerged from Qiu Lin's index finger and flew all the way to the sky. Suddenly, that red circle of light quickly expanded, turning into a huge red halo, staying above Qiu Lin and Lu Xi's heads.

Runes and patterns appeared in the aura that Lu Yu couldn't understand, looking like a combination of totems and spells.

Lu Yu carefully looked at the runes that appeared in the circle, those runes looked like scribbled fonts, and those patterns were large and small, constantly rotating back and forth. Some patterns resemble stars and moons, while others resemble lions and tigers.

The patterns were constantly moving around the center of the circle, and suddenly they merged into one, forming a red dot in the center of the circle that glowed intensely. The runes vanished, and the circle of light outside the dot vanished, leaving only a red dot that glowed intensely and remained motionless in the sky.

Slowly, the light of the dot dimmed, leaving only a small dot that glowed faintly red.

Qiu Lin lowered his head and looked at Lu Yu and said, "Lu Xi, I have made the mark." If you want to come to this space to mine minerals, you can just ask me to bring you here. At the moment, you don't have the skill to sense this mark. ”

Lu Yu nodded, continued to look at the giant luminaries around him, and said, "What kind of minerals are these lumines?" ”

Qiu Lin replied, "Most of them are energy stars. There are also some raw materials that can be used to forge immortal weapons. By the way, did Master Zun give you a book about immortal weapons? ”

Lu Yu thought about it carefully and said, "Yes, Senior Brother Qiu Lin, Master Zun gave me a copy of the "Overview of the Essentials of Refining". ”

Qiu Lin said in an affirmative tone: "I have studied this book before. It introduces a lot of raw materials for refining immortal artifacts and their uses. You go back and study this book, and then you'll find that when I bring you to this plane again, you'll know a lot of minerals here. ”
