The system is the proficiency panel

After diving into the seabed, the first thing Lin Ji saw was an extremely huge palace. There was a plaque hanging at the entrance of the palace with the three words "Xuanming Palace" written on it, and various gorgeous decorations.

"Xuan Yao King, this Xuanming Palace should not be built by the demon race, right?"

The three of them arrived at the palace gate, and Lin Ji asked after taking a few glances.

"You can just call me Xuanmu. It was definitely not built by the demon race. I found it in the Endless Sea. The entire palace was buried at that time. If I hadn't happened to be standing on it, I wouldn't have found it. Then I moved it back and used it as my cave."

Xuan Mu's tone sounded a bit boastful, but Lin Ji could understand. This palace looked really impeccable. He suspected that this might be left behind when the Ten Thousand Stars Realm invaded this universe.

Walking into the Xuanming Palace, the interior is very luxuriously decorated. All the furnishings inside are made of purple gold, and a very advanced formation is used to protect them firmly in the palace, preventing the outside air from circulating.

There are dozens of buildings inside the Xuanming Palace. The layout of the buildings is similar to that of human buildings, but they are more luxurious and gorgeous than human buildings. With curiosity, Lin Ji looked at Xuanmu and asked.

"Xuanmu, have you checked this palace? Do you know what's inside?"

"I've seen it. Apart from the decorations, the entire palace is empty. There's nothing there. Someone must have emptied it out in advance."

Xuan Mu shook his head. He had checked the situation in Xuanming Palace and found nothing inside. Lin Ji naturally would not believe all of this, so he spoke.

"Is that so? Let's go shopping then."

Upon hearing this, Xuanmu took Lin Ji to tour the Xuanming Palace. Indeed, they did not find anything unusual. Lin Ji reluctantly returned to the main hall with Xuanmu and sat down.

"Xuanmu, I'm tired of seeing Xuanming Palace. Don't you go to the Endless Sea often? You must have got something good. Take it out and let us see it."

At this time, Qingniao, who was following the two of them and was bored, saw that they had returned to the main hall, and immediately seized the opportunity to speak bluntly. Xuanmu looked at her speechlessly with a twitching mouth, and shouted in his heart.

"Bluebird! You can't sell me like this, at least be more tactful!"

Lin Ji on the side looked at Qingniao with admiration. There were also some spiritual objects in the Xuanming Palace. Although Xuanmu said that he could take a few at will, their quality was not high and they could only be effective for ordinary foundation building. So Lin Ji did not take any. He thought that when he left, Wutong Ancient Tree, as a senior, would definitely give him some things, so Lin Ji did not care. But he did not expect Qingniao to sell Xuanmu.

"Look at my memory. I forgot all this in an instant. I am sorry for neglecting you. Please forgive me. I will take it out now."

As Xuan Mu spoke, he took out five spiritual objects from his storage ring and placed them suspended between the three people. Seeing the spiritual objects suspended in the air, Lin Ji immediately became interested.

"These five spiritual objects are: meteorite iron of the gold element, sycamore branch of the wood element, mirage pearl of the water element, flaming fruit of the fire element, and jade marrow of the earth element. If you are interested, just pick two and take them."

Xuan Mu said generously, and then began to introduce their origins and functions. After listening, Lin Ji chose the Mirage Pearl and the Wutong Branch without hesitation. The Mirage Pearl was left behind by a second-level mirage turtle that was good at illusions. It was helpful for him to practice Mirror Flowers and Water Moon, while the Wutong Branch was prepared for Xiao Ningxue.

After seeing Lin Ji make his choice, Xuan Mu felt a little distressed inside, but he looked very happy as he pushed the two spiritual objects in front of Lin Ji, put away the other spiritual objects, glanced at the blue bird watching the show on the side, and then asked Lin Ji.

"Diaozi, do you still want to continue to look around the North Sea?"

"No need, just understand it. Now that I have obtained this spiritual object, I want to go back to practice, so I won't bother you, Xuanmu anymore."

Lin Ji answered very straightforwardly. He had a basic understanding of the situation in Beihai and had also received the benefits. He calculated that it was time to go back and practice.

Xuan Mu nodded, and then the three of them left the palace and returned the same way. Just as they were leaving the North Sea Stele, Xuan Mu suddenly said something malicious.

"Bluebird, we haven't had a fight for a long time. Today we are both free, so why don't we have a fight?"

"No, no, I still have to send Daozi back. I'm leaving first."

Bluebird said hurriedly, then grabbed Lin Ji and flew quickly into the distance. Xuanmu looked at the fleeing Bluebird and his eyes narrowed into a line.

"Just wait and see, little girl."

After returning to the cottage by the lake, Bluebird realized that no one was chasing them, so he let go of Lin Ji with a sigh of relief, and said unhappily to him as he looked at him trying to hold back his laughter.

"Daozi, I helped you get two spiritual objects, don't you want to thank me?"

"Tell me, why are you helping me so much? Is it because of Feng Tian?"

Facing Lin Ji's teasing, Bluebird immediately retorted.

"No, I hope you don't take the initiative to ask me for spiritual objects. I don't have many high-level spiritual objects now, and most of them are used to cultivate Feng Tian."

"Well...what if Senior offers to send me off?"

Lin Ji smiled and asked back. Qingniao also knew that he had already given in and couldn't push his luck any further, so he answered.

"I don't care about that situation, but you can't ask for it."

"Okay, I agree, but why are you so afraid to spar with Xuan Mu? We are both Jindan, so is there a big difference in strength?"

Lin Ji asked curiously, he really didn't understand the classification of Jindan Zhenren's strength, and the most recorded in the book was that the one who could control the five elements was a Jindan.

"It's very big. After condensing the five elements into a golden elixir, you have to build your own world based on the golden elixir. When you practice to this level, you no longer need to rely on external spiritual energy. The spiritual energy produced by your own world can basically be self-sufficient. The size of the world inside my body is now only equivalent to half of the East Continent, while Xuanmu has already exceeded the East Continent and can start to try to materialize the rules. Of course, I am no match for him. If I don't run, I will be beaten!"

After hearing Qingniao's words, Lin Ji suddenly realized that the strength of this Jindan Zhenren was measured according to the size of the world inside his body. After figuring it out, Lin Ji no longer dwelled on this issue and changed the subject.

"Okay, let's not discuss this anymore. I need to practice. If you have nothing else, go back."

As Lin Ji said this, he walked towards the house. Qingniao looked at his back and shouted.

"Do not forget our agreement!"

In response to this, Lin Ji just waved her hand and walked into the house. Seeing this, Qingniao also left. She also wanted to go and see how her fellow tribesmen who practiced the shapeshifting technique were doing.

Xuantian City Lord’s Mansion.

Luo Youran was sitting in front of the imperial desk, looking at the letter sent from Tianshu City in his hand, his face slightly annoyed. The content of the letter was: The portal was being used smoothly and had been running for two days without any abnormalities. However, several accidents occurred. Some cultivators passed half of their bodies through the portal but not all of them. The portal closed naturally when the time was up, resulting in the death of six Qi-cultivating cultivators and the survival of three. After checking, they found that they had a common point in that they had all read a book called "Time and Space" in the library of the cultivator school. Now it is suspected that they did this intentionally for the sake of cultivation.

"Master, you said that you should open up the skills to all the cultivators, saying that this would help discover geniuses, but in the end, no geniuses were discovered, and many fools were killed!"

Thinking of this, Luo Youran took out two pieces of spiritual paper and started writing, then stamped them and sent them out.

The first letter was delivered to Tianshu City, and its content was: Send formation masters to set up formations around the teleportation array to block the surrounding monks. The monks who use the teleportation array must be carefully checked, and any monks who are found to have borrowed "Time and Space" are prohibited from using the teleportation gate.

The second letter was given to the monastic school, and its content was: the confidentiality level of the cultivation methods of special "forces" such as "Time and Space" will be raised, and only those who have cultivated a "force" or established a foundation before the age of 18 can borrow it.
