The system is the proficiency panel

While the ancient Wutong tree was still discussing, Lin Ji had already returned to the Buluo City. After confirming that it was safe, Lin Ji spoke to Hou Wen beside him.

"I will be leaving Bu Luo City and returning to Xuan Tian Sect tomorrow. I will not be going to the Misty Forest tomorrow."

"I won't return the spirit stones, but I'll give you six low-grade spirit stones for the three monster corpses. I'll just give you the spirit stones back."

Hou Wen handed the spirit stone to Lin Ji with a look of joy on his face and left. Seeing his happy expression, Lin Ji knew that there must be some profit to be made from this corpse, but Lin Ji didn't care. The low-grade spirit stone could only restore his spiritual power for the time being.

He returned to the inn and asked the shopkeeper to prepare spiritual food. Because it was already afternoon and there were not many Xuantian Sect disciples here, the spiritual food made from demon tiger meat was soon brought to Lin Ji's table by the shopkeeper himself. Looking at the delicious food in front of him, Lin Ji stopped the shopkeeper who was about to leave and said.

"Shopkeeper, do you know any suitable gifts for Taoist couples in Buluo City?"

Hearing this, the shopkeeper looked at the handsome but still somewhat childish Lin Ji with a strange expression. Putting away his curiosity, the shopkeeper put a smile on his face and said to Lin Ji.

"Ever since Yu Zhenjun came back more than a decade ago, Buluo City has not encountered a beast tide again, and it has slowly prospered. Xuantian Sect has also set up a business in Buluo City called Xuanjin Business. Disciples of Xuantian Sect can get discounts. There are many items in there, and maybe there is something you like."

"Thank you, shopkeeper, for informing me."

After that, the shopkeeper left, and Lin Ji began to eat the spiritual food in front of him. Most spiritual food is not only delicious but can also replenish the spiritual power in the body. Some special spiritual food can even be regarded as elixir.

After eating, Lin Ji got up and left the inn to look for Xuanjin Trading Company. He soon found it. The floors were not very high but it occupied a large area. There was an entrance in four directions. Lin Ji entered from the intersection close to the spaceship.

There were not many people in the hall. After entering, the first thing Lin Ji saw was a several-meter-high introduction board, which listed what products or functions each area had. Lin Ji memorized them one by one, and then decided to buy some clothing-related magic tools first.

'It feels a bit like shopping in a supermarket in my previous life...'

Lin Ji came to the clothing and magic weapon sales area, and saw pieces of clothing hanging in the air separated by transparent walls. Below was a long counter and several mature female cultivators who had reached the third or fourth level of Qi training. They probably came here to work because they had no talent for cultivation. There were also several customers communicating with them.

"I'll choose white clothes, and black suits You Ran better."

Lin Ji walked forward and looked at the pieces one by one, and selected two that looked good. At this time, a female cultivator at the counter came over and asked respectfully.

"Sir, do you have any clothes you like?"

"What level of magical instruments are these two? How many spirit stones do they cost?"

Lin Ji pointed at two pieces of clothing in the air and said that the female cultivator in front of him had cast some magic, and the clothes that Lin Ji pointed at in the air automatically flew down and hovered above the counter.

"The white one is Bai Xuan Yi, a low-grade magic weapon. Inputting spiritual power can stimulate a spiritual shield that can withstand a full-strength attack from an ordinary Qi training level 7 cultivator. The price is 40 low-grade spiritual stones. The black one is Hei Yu Yi, a low-grade magic weapon made of the feathers of a foundation-building crow and spiritual silk. It can speed up the cultivator and can also open a shield like Bai Xuan Yi. The price is 60 low-grade spiritual stones. I wonder if the customer is satisfied."

"How much cheaper can I get since I'm a disciple of Xuantian Sect?"

After listening to the female cultivator's fluent introduction of the two pieces of clothing, Lin Ji, who originally thought that he only had 70 spirit stones left, felt a little embarrassed. He really didn't have that many. Thinking of the shopkeeper's words, he took out the Xuantian Sect jade token and showed it to the female cultivator.

"Sir, I need to verify it. Please give it to me first."

After seeing the jade token, the female cultivator actually took out a card reader, took the jade token and swiped it to verify whether it was authentic.

"Dear guest, you only need to pay the cost price of 20 low-grade spirit stones to purchase it."

Lin Ji took out the spirit stone from the savings bag and handed it to the female cultivator, then took the two pieces of clothing and put them into the savings bag, and left with the female cultivator's respectful greeting.

"I didn't expect Xuantian Sect's welfare to be so good. I didn't have such an intuitive feeling in the sect. Once I got outside, everyone would give me some respect."

Lin Ji, in a good mood, continued to stroll around other areas. He thought he should make good use of such a good benefit.

Finally, Lin Ji used 40 spirit stones to buy two five-hundred-year-old wood hearts and a bottle of heavy water, which could speed up the process of the cultivator's comprehension of power. The two wood hearts looked ordinary, like ordinary wood, but the bottle of heavy water was 2 times heavier than ordinary water.

Looking at the 10 spirit stones left in the savings bag, Lin Ji left Xuanjin Trading Company contentedly, returned to the inn, took out Mu Xin and started practicing.

Using his mental power to probe into the heart of the wood, Lin Ji instantly felt a strong vitality and wood-attributed power.

"Is this wood heart still alive? It has strong vitality. If I find a sacred place to plant it, I think it will grow into a new tree after a while."

Of course Lin Ji would not do such a thing. He used his mental power to guide the wood aura and vitality in Mu's heart into his body, feeling the changes in his body.

"It feels so comfortable. I feel that every vital cell that touches the wood is activated. My body also has a special feeling. My understanding of growth is also clearer."

It was not until dark that Lin Ji slowly absorbed the spiritual energy and vitality in the wooden heart. He opened his eyes and looked at the wooden heart that had turned into sawdust in his hands. He scattered it on the ground and summoned the system.

[You absorb and comprehend the vitality and spiritual energy of the hundred-year-old wood heart. Changchun Gong proficiency +20]

Looking at the progress prompted by the system, Lin Ji happily entered the Trial Tower and began the battle.

The next morning, Lin Ji boarded the spaceship back to Xuantian Sect. After all, if Xuan Lin was really the son of the Demon King, it would be dangerous to stay in the Misty Forest, so he decided to stay out of the spotlight.

After waiting for a while, the spaceship took off and left. Lin Ji was in a good mood looking at the surrounding scenery. After a while, Lin Ji took out the sect's jade token to see if he could contact the sect.

After confirming that everything was OK, he sent news of his return to Xiao Ningxue and Luo Youran respectively.

……

In a classroom in the Formation Hall of Xuantian Sect, Xiao Ningxue was practicing drawing formations. There were a few people like her beside her. A foundation-building cultivator with white hair and beard was walking back and forth, watching the drawing process and occasionally giving some pointers.

"Xiao Ningxue, you drew well and have made great progress. Other disciples should learn from her. You can take a rest first."

The old man came to Xiao Ningxue and was very happy to see the formation she had completed. He praised her and told her to rest. Xiao Ningxue breathed a sigh of relief after hearing that, and got up to leave. She had studied with Yu Yue at night for the past two days and practiced in the Formation Hall during the day. She also couldn't fall behind in her usual practice, so she was really tired.

Walking to the door and looking at the surrounding mountains and trees to relax her mind, Xiao Ningxue took out the jade token and was about to look at the book stored in it when suddenly a message popped up. It was Lin Ji who sent a message saying that he would be back soon. Xiao Ningxue returned to the classroom with a smile on her face.

"Master Zhou, I have something else to do this afternoon and cannot continue studying here. I hope you can understand."

"Of course, but you must come tomorrow. It's time for you to officially repair some minor problems with the formation."

After hearing what Master Zhou said, Xiao Ningxue nodded to show that she understood and left.
