"Master, the spiritual food is ready."

The next morning, Luo Youran prepared spiritual food with the spiritual materials distributed by the Earth Institute every month, and then knocked on Lin Ji and Xiao Ningxue's doors one by one. Hearing the knock on the door, Lin Ji stopped practicing, got up, opened the door and went out.

Xiao Ningxue and Luo Youran were already waiting for him outside the door. Seeing this scene, his depressed mood due to a whole night of practice improved a lot, and the three of them went downstairs to eat together.

"You Ran, your cooking skills have improved a lot compared to last time. I didn't expect you to have such a good talent for cooking."

Lin Ji, who was tasting the spiritual food in front of him and felt it was delicious, praised it. Xiao Ningxue beside him also nodded in agreement. Facing their praise, Luo Youran said.

"The spiritual materials given by the sect are so good that they taste good. I just processed them casually. Can you guess how many spiritual stones this table costs?"

"In the city of Bu Luo, the store that provides spiritual food and accommodation costs one low-grade spiritual stone a day. Even if the ingredients in the sect are more advanced, it won't be much higher. I guess five spiritual stones."

"Then I'll guess 20."

"You're all wrong. It's about 40 low-grade spirit stones. The price of the ingredients is about the same as what you guessed, but this is expensive!"

As he spoke, Luo Youran took out a small transparent bottle and shook it in front of the two of them. There was a silver transparent liquid in it.

"Moonlight Liquid can be used by those in the Qi training stage. Long-term use can enhance comprehension and talent. This small bottle can be used three times, which is about 100 low-grade spirit stones. Moreover, this thing is in short supply. Only the foundation-building cultivators in the Water and Wood realms can condense it."

Reaching out to take the small bottle, Lin Ji could feel the bottle was slightly cold. Luo Youran continued.

"Master, the Moonlight Liquid given by the sect is enough for the three of us. They must know the existence of Ningxue and me, and understand that you will definitely share it with us, so the sect decided to directly supply the three of us."

"The sect is indeed very good to me. By the way, do you know where in the sect can help me practice sword skills?"

"Of course there is. This is also considered a secret realm. There are also places for practicing the five elements and other weapons. The place for practicing sword energy is called the Sword Tomb. It is said to be made up of the swords of many deceased monks in the sect and the failed swords in the Weapon Refining Hall. It is then surrounded by a formation to prevent the sword energy from leaking out."

"Well, I'll go to the sword tomb after I finish repairing the yard. You guys can go and do whatever you want."

After eating, Xiao Ningxue and Luo Youran left the courtyard for their own business. Only Lin Ji stayed here, practicing while waiting for the people who were repairing the courtyard to come.

While waiting, Lin Ji released five sword energies to form the shape of short swords, and controlled them to perform sword moves in the air to exercise his control ability.

After a while, news came from the restriction. Lin Ji thought it should be someone arranged by Luo Youran. After the restriction was removed, a girl with ordinary looks walked in. Lin Ji walked up to her and said.

"Are you the person You Ran hired to repair the yard?"

"Yes, my supervisor asked me to come. Can I start now?"

After getting Lin Ji's nod, the girl in front of him took out the tools from her savings bag. She was practicing earth-attributed skills, so she quickly repaired the yard. After the repair, she left immediately. No one knew what she was afraid of.

Seeing that the yard was successfully repaired, Lin Ji took out the jade token and found the location of the sword tomb according to the map and left.

"It's really hard not to be able to fly!"

Lin Ji was running very fast, and several people were flying over him, because the sword tomb was not in Xuantian Peak, but was distributed on the surrounding mountains like other secret realms. Lin Ji had not yet reached the fifth level of Qi training and could not fly, so he could only run.

A few minutes later Lin Ji reached another mountain peak. After using his spiritual power, he could run nearly 300 meters per second at full speed. It didn't take him much time, but he was really annoyed to see others flying while he could only run.

This mountain is a sword tomb from the mountainside. From the outside of the formation, Lin Ji saw many swords scattered all over the mountain. There was a house in front of the formation with a young monk sitting inside. He should be the guardian of the formation. He noticed Lin Ji and said.

"Please show me the jade token!"

When Lin Ji heard this, he immediately took out the jade token and handed it to him. The guard took the jade token and swiped it through the card slot next to it. Then he quickly returned the jade token and let Lin Ji in.

As soon as he entered the sword tomb, he was greeted by the chaotic sword energy that filled the entire space. Lin Ji used his spiritual power to protect his body and walked towards a higher place. Along the way, the various sword energy attributes opened Lin Ji's eyes.

"I've only advanced a few hundred meters but the resistance is already so great. My spiritual energy consumption is also slowly increasing. It seems I can only stay at this altitude for now."

Lin Ji found a relatively open place to sit down and began to practice. He closed his eyes and used his mental power to search for any residual force on the surrounding swords.

No, none of the swords in this area had any residual sword energy. However, his physical body and spiritual power could not withstand the chaotic sword energy. Lin Ji had no choice but to stay here to practice. However, even so, the training effect brought by the sword tomb was still very good.

[You have practiced in the Sword Tomb, and your understanding of sword power has been enhanced. Sword power: Control proficiency +1]

Lin Ji practiced inside until his spiritual energy was exhausted before leaving the sword tomb. At this time, only two hours had passed and the sun was shining brightly. The movement of Lin Ji coming out attracted the attention of the guard, who walked over and stared at Lin Ji.

"You are very strong. You can actually last for 2 hours at the fourth level of Qi training. The jade card shows that your name is Lin Ji. Are you the genius that Senior Brother Ye mentioned?"

"If you are talking about Uncle Ye Xun Ye, then the genius he is talking about is me!"

Faced with the guard's questions, Lin Ji did not hesitate to admit that he was the genius, and the guard chuckled.

"My name is Bai Bin, you can just call me Senior Brother Bai. I'm still young and don't want to be called Uncle Master. I'm a 20-year-old foundation-building cultivator, currently assigned by the sect to guard the sword tomb. There's no need to introduce yourself. Senior Brother Ye has already told the inner sect about your situation. Senior Brother Ye highly respects you, which makes me very interested in your strength. How about I lower my cultivation level to compete with you?"

"Okay, but I need to recover my spiritual power first."

Faced with Bai Bin's invitation to fight, Lin Ji was also very interested and agreed immediately, taking out the spirit stone to recover quickly.

After sucking up several spirit stones, Lin Ji stood up to signal that he was ready. Bai Bin hung a sign at the door of the house to indicate that he was not there and asked people to wait a moment if they wanted to enter the sword tomb. Then he took Lin Ji down the mountain to an empty piece of land.

"I won't bully the weak. I'm also at the fourth level of Qi training. You can attack first."

Hearing this, Lin Ji immediately controlled three sword energies to leave his body and rush towards the opponent, attacking from different angles.

Ding Ding! Bai Bin's basic swordsmanship was very solid. He perfectly defended and destroyed the three sword energies. He then smiled at Lin Ji, but did not actively attack. Seeing this, Lin Ji condensed six transparent flying swords composed of sword energy around his body, which also contained double sword power. This was the current limit of Lin Ji's control.

Swoosh! The transparent flying sword flew through the air at an extremely fast speed.

Sensing that the power contained in the sword energy was not comparable to the previous ones, Bai Bin became serious. With his fourth-level Qi training skills, he instantly slashed out a hundred-meter-long golden sword energy, hoping to solve the problem in one go.
