The system is the proficiency panel

The morning sun shone through the window lattice into the house, casting mottled light and shadows on the floor. Lin Ji opened his eyes and felt the soft touch of the person in his arms. Luo Youran curled up in front of his chest, her black hair falling on the pillow like a waterfall, her breathing even and gentle. Her eyelashes trembled slightly, and there was a hint of satisfaction at the corner of her mouth, as if she was still immersed in a sweet dream.

Lin Ji gently stroked her hair, his fingertips lingering on her fair cheek, his heart filled with infinite tenderness. After three years of separation, the warmth at this moment seemed particularly precious. He lowered his head and kissed her forehead. Luo Youran seemed to be aware of it and moved slightly, but she did not wake up. Instead, she rubbed against his arms, like a lazy cat.

Lin Ji couldn't help but chuckle, and was about to tease her again, when Luo Youran opened her eyes dazedly and met Lin Ji's smiling eyes, her cheeks slightly flushed. Just as she was about to speak, Lin Ji leaned over and whispered in her ear.

"Get some more sleep."

Luo Youran shook her head, propped herself up, and let her purple dress slide off her shoulders, revealing her jade-like skin. She raised her hand to gather her messy long hair and spoke softly.

"I send you."

After the two dressed up, they walked out of the room together. The morning dew in the courtyard had not yet dried, and the air was filled with a faint floral scent. Luo Youran personally straightened Lin Ji's clothes, her fingertips lingered on his chest for a moment, her eyes full of reluctance.

"Be careful."

She whispered, so quietly that it was almost inaudible.

Lin Ji held her hand and spoke gently.

"Don't worry, I'll be fine. Wait until I get back."

Before he finished speaking, his figure turned into a streak of light and disappeared into the morning light.

……

Under the dark red sky, the outline of the Rift City was like a dormant giant beast. The rune array on the city wall flashed a light blue light, resisting the erosion of the abyss. Dao Yan and Yun Shitian stood outside the city gate, looking up at the sky from time to time, obviously they had been waiting for a long time.

"Why haven't you arrived yet?"

Yun Shitian kicked the gravel under his feet impatiently, and the golden armor was still dazzling in the dim light.

Daoyan was wearing a plain white gown with her ponytail tied up high, looking capable and cool. She glanced at Yun Shitian and said lightly.

"Why are you in such a hurry? Since Lin Ji said he would come, he will definitely not break his promise."

As they were talking, a silver light streaked across the sky in the distance and landed in front of the two of them in the blink of an eye. When the light faded, Lin Ji's figure emerged clearly, his robe fluttering in the wind, his expression calm.

"Awaited."

He smiled.

Yun Shitian's eyes lit up, he strode forward and patted Lin Ji on the shoulder.

"You're finally here! We've been waiting so long that the flowers are all withered!"

Daoyan also walked forward, a hint of joy flashed in his eyes, but he quickly regained his composure.

"Lin Ji, you're here."

Lin Ji nodded, his eyes swept across the two people's faces, and found that their expressions were different, so he couldn't help but ask.

"What's wrong with you? You all have that expression."

Yun Shitian laughed and spoke directly without any further ado.

"Early this morning, the four True Lords all sent messages, agreeing with your method! Lin Ji, how did you do it?"

He took a step closer, his eyes full of curiosity and admiration.

"You've convinced even an old stubborn person like my master. It's incredible!"

Although Daoyan didn't say anything, his eyes revealed the same doubt, and he waited quietly for Lin Ji's answer.

Lin Ji smiled, his tone calm.

"I accidentally got a spiritual object called Star Liquid. True Lord Yu Shui used it to make a deal with the three True Lords, and they agreed to my request."

"Star fluid?"

Yun Shitian scratched his head.

"What kind of treasure is that? How could it make the True Lords excited?"

Daoyan frowned slightly and said softly.

"The spiritual object that Yuanying Zhenjun cares about must be very important."

Lin Ji nodded.

"It is indeed precious, but for me, I can't use it now, so I might as well exchange it for something more important."

Yun Shitian and Daoyan's excitement suddenly faded after hearing this. Yun Shitian put away his smile and became serious for once.

"Lin Ji, you paid such a high price for this, is it worth it?"

Daoyan also whispered.

"Star fluid is so precious, you could have saved it for future breakthroughs..."

Lin Ji couldn't help but laugh when he saw the two of them looking depressed.

"Don't worry, there are still a few drops of Star Fluid left, and at my current level, I can't fully utilize its power. Rather than leaving it useless, it's better to use it to solve the crisis at hand."

Yun Shitian was silent for a moment, then suddenly laughed out loud and patted Lin Ji's back heavily.

"Great! You are worthy of being the number one genius on Kaiyang Star! Since you said so, I won't be pretentious! Let's go into the city and discuss in detail!"

Daoyan's brows also relaxed and the corners of his lips slightly raised.

"Lin Ji, thank you."

Lin Ji shook his head.

"No need to thank me, we are all here for Kaiyang Star."

The three of them walked towards the city gate side by side. When the guards of the Rift City saw Lin Ji, they saluted one after another, their eyes full of awe and admiration.

Yun Shitian said excitedly as he walked.

"Lin Ji, you really made a great contribution this time! After the four True Lords agreed to restrict the exploration of the abyss, the cultivators of all sects breathed a sigh of relief. You didn't see how miserable those cultivators who were eroded by the abyss were when they were sent back..."

Daoyan added softly.

"Moreover, the True Lords have also ordered the construction of a teleportation array in the occupied mineral veins, which will be maintained by the array masters led by Tianshu City. This will greatly improve the efficiency and safety of exploration."

After listening to Daoyan's words, Lin Ji nodded slightly, then changed the subject and looked towards a certain place in the city.

"How is the elf Elvis doing now?"

Daoyan's bare hands gently brushed the scattered hair on his temples, and the sound was like the flowing of a clear spring.

"He seems to have accepted his fate these past two days and is no longer obsessed with finding a companion."

She paused, a thoughtful look in her eyes.

"He began to talk to the monks who were guarding him, and seemed to want to get information about us."

"Oh?"

Lin Ji raised his eyebrows slightly.

"I asked the guard monk to build a good relationship with him and reveal some basic information appropriately."

Daoyan was speaking when he suddenly remembered something and a faint smile appeared on the corner of his lips.

"He was quite surprised at the way we cultivators practice."

Yun Shitian crossed his arms, his golden armor glowing coldly under the dark red sky.

"It can't be that we are the only one who revealed it, right? Did that pointy-eared guy say anything valuable?"

Daoyan took out a jade slip from his sleeve and tapped it with his fingertips. A curtain of light unfolded in front of the three people.

"Based on our conversations over the past two days, Aetheris is a vast world where gods and demons battle against each other."

A projection of the flat world appeared on the light screen, with images of the central light core and twelve floating cities.

"Their world is an infinite continent, the size of which is unknown."

Daoyan's voice was filled with a hint of amazement.

“Mainly composed of seven ‘primordial realms’, each with unique geography and civilization.”

Lin Ji stared at the floating city's Silver Dome Crown and the Dwarf's Star-Forging Throat described by Elvis on the screen, his eyes full of curiosity.

“The battlefield of faith where light and darkness interweave… is truly marvelous.”

He reached out and touched the twelve floating cities that refracted the central light core in the projection. According to Elvis' description, they were used to control the day and night cycle of Aetherius and were constantly guarded by the elves.

"Each plane is different. In comparison, our universe is indeed a bit monotonous."

Daoyan put away the jade slip and said softly.

"Elvis mentioned that the battle between gods and demons in their world is essentially a battle for the power of faith. The gods need the prayers of believers to maintain their power, while demons directly plunder souls."

The three of them were silent for a moment. The psychic turrets on the city wall in the distance were flickering with light, forming a sharp contrast with the dark red sky of the abyss. Lin Ji suddenly chuckled.

"It seems that the ways in which strong people from different universes pursue power are similar."

Yun Shitian moved his shoulders, and the armor made a crisp clash sound.

"Who cares about gods and demons? They can't get in our way now anyway."

He looked out at the temporarily peaceful wasteland.

"The two demon lords suffered heavy losses in the past two days, so they have become much more peaceful."

“It’s really a rare tranquility.”

Daoyan straightened his sleeves and looked at Lin Ji.

"I'm going to practice first. I haven't completely digested the blood marrow crystal I just got."

Lin Ji nodded.

"Well, I am also going to try the effect of the blood marrow crystal."

Yun Shitian waved his hands.

"Let's go, I'm going to practice too, I can't fall too far behind you."

The three of them smiled at each other, then turned into streams of light and disappeared.
