The system is the proficiency panel

After fruitless thinking, Lin Ji adjusted his mindset and stood up to encourage everyone.

"Don't think too much. Have a good rest. Xuantian City will continue to send us elixirs, magic tools, and spirit stones. We must drive the sea tribe back into the sea. From today's battle, we can see that the sea tribe is just a large number, but not very strong. As long as we maintain sufficient spiritual power, even without the Golden Core Master, we have a good chance of winning."

At this time, a man came in trotting, saluted respectfully to Lin Ji, and said that Tianshu City had brought support. Lin Ji and others left the hall and went outside to see the situation.

The huge Tianshu City in the distance was flying towards this side quickly, followed by other spaceships around it. Finally, it stopped outside the Sunset City formation under the gaze of Lin Ji and others.

"Let's go, the supplies have arrived, go receive them and have someone distribute them."

Lin Ji took some monks to the top of the city to receive supplies, while Lin Ji flew to Tianshu City. There were some things he had to ask Xiao Ningxue.

When they arrived at Tianshu City, Lin Ji found many formation masters repairing the damage to the formation. Most of them were the old subordinates of He Ming and the other two, and were now considered members of the Xuantian Sect. They all saluted respectfully when they saw Lin Ji. One of the formation masters who had reached the Foundation Establishment stage spoke.

"Daozi, the city lord knows you will come, and she is waiting for you at the city lord's mansion."

Hearing this, Lin Ji nodded to indicate that he understood, and quickened his pace towards the City Lord's Mansion.

Soon Lin Ji found Xiao Ningxue on the top floor of the wooden building. She was sitting on a chair, looking up at the starry sky. Only then did Lin Ji realize that the moonlight today was particularly dim.

"Brother, Jindan Zhenren is so terrifying!"

Lin Ji, who had just arrived at the top floor, was a little confused when he heard this. He followed Xiao Ningxue's gaze to the starry sky and suddenly discovered the reason why the moonlight was dim today.

Looking from Kaiyang Star, the moon is now covered with holes and cracks, three of which are particularly obvious, spanning the entire moon, and Lin Ji can clearly see that those cracks are slowly increasing.

"Yes."

Lin Ji picked up Xiao Ningxue and sat down, holding her tightly to enjoy this moment of peace. Xiao Ningxue also curled up quietly in Lin Ji's arms without moving. After a while.

"Ningxue, how many spirit stones do I need to continue using Tianshu City to launch that attack?"

"At least one thousand middle-grade spirit stones. The spiritual energy purity of low-grade spirit stones is not enough."

Lin Ji was shocked by Xiao Ningxue's answer. Xuantian Sect could barely come up with a thousand middle-grade spirit stones, but Lin Ji felt that if he really used them to charge Tianshu City, he would be scolded to death by the True Lord and the True Man. There might be only a few middle-grade spirit stones in a mine, and their value was not comparable to that of low-grade spirit stones. As for high-grade spirit stones, Lin Ji had never heard of anyone mentioning them. It was estimated that only the True Lord might have them. Now Lin Ji had a question.

"How did Tianshu City manage to gather enough spiritual energy? The spiritual absorption formation alone is not enough!"

"At that time, I stayed in Tianshu City with Master He and the other two to learn the formation. A few days later, I asked them how Tianshu City was kept running, but they refused to tell me. It was not until they handed Tianshu City over to me some time ago that they told me the reason. Brother, I will take you to see it and you will understand."

Xiao Ningxue patted Lin Ji's arm and asked him to let go of her. The two got up and left. Under the guidance of Xiao Ningxue, Lin Ji passed many formation tests and came to the secret room under the City Lord's Mansion.

I saw a very small piece of debris floating in the air, but a huge amount of spiritual energy surged out of it, was absorbed by the surrounding formations, and then formed a spiritual light band that disappeared into the secret room. Lin Ji knew at the first sight that this was the core of Tianshu City.

"What is this fragment?"

"I don't know. This was discovered by Master He and his two companions at the bottom of a spiritual pond by chance. It was because of this that they came up with the idea of ​​building Tianshu City, because this fragment can supply the spiritual energy consumption of Tianshu City. According to Master He, this fragment seems to have unlimited spiritual energy, but there is an upper limit to the spiritual energy output per second."

Xiao Ningxue introduced the origin and function of the fragment. Lin Ji took a few steps forward to approach the fragment and feel the spiritual energy it exuded at close range. It was very pure.

“Can I touch it?”

"Yes, it doesn't pose any danger."

Lin Ji reached out and grabbed the fragment, silently reciting the system.

(You found a fragment of Tiandao. After Tiandao died, it broke into countless pieces. This is one of the small pieces. Except for releasing spiritual energy, it has lost all special abilities.)

(The Heavenly Dao has perished, and this fragment has lost consciousness. Will it invade?)

Looking at the system prompt message, Lin Ji's body was shocked.

"The Heavenly Dao has died? No wonder the golden elixir could not be cultivated at the beginning. If the Heavenly Dao is dead, where would the thunder tribulation come from for you to overcome and transform you? In this case, the Heavenly Dao may have died 3000 years ago."

The more Lin Ji thought about it, the more annoyed he became, so he simply stopped thinking about it and communicated with the system.

'What is the purpose of occupying the fragments of the Heavenly Dao? And how can one occupy them?'

(The effect can only be discovered after invasion. Although only fragments are left, the Heavenly Dao is the origin of the universe, so the system recommends invasion)

(The Heavenly Dao fragments have lost consciousness. You only need to cut your soul and send it into the fragments to complete the occupation. Warning! Depending on your current soul strength, you may need to cut off a quarter or even half of your soul to complete the occupation.)

(Because the system was born from your soul, you will lose some of the system's functions after cutting your soul. The lost functions will be added to the Heavenly Dao fragments. You can choose what functions to lose)

Looking at the information from the system, Lin Ji fell into deep thought, and then immediately made a decision. To occupy the fragments of Heavenly Dao, this suggestion was very tempting, but he didn't have time now. It was impossible to tear his soul apart while the Sea Clan was outside. This would cause him to suffer heavy damage for a period of time, making him unable to fight. He would try again after he had survived the crisis of the Sea Clan.

"Brother, what's wrong? I saw you were in a daze for a long time."

Xiao Ningxue walked up to Lin Ji and waved her hand in front of his eyes. Lin Ji came to his senses and grabbed the dangling hand in front of him.

"Nothing, I know what this fragment is, it's very important."

Lin Ji said as he pulled Xiao Ningxue out. The fragments of Heavenly Dao were of no use to him now, so they should leave first.

"What is this fragment?"

"A fragment of the Heavenly Dao."

Facing Xiao Ningxue's question, Lin Ji had no intention of hiding anything. Although Xiao Ningxue didn't understand what this fragment of the Heavenly Dao was, she felt very happy about Lin Ji's trust in her. She happily hugged Lin Ji's arm and didn't ask any more questions.

Following the dim moonlight, the two prepared to return to the room to practice. Before entering the room, Lin Ji looked up and wanted to continue looking at the moon.

"There are more and more cracks. Will the moon be blown up in the end? If it is the moon of the Earth, there should be aerospace garbage left by humans on it... Aerospace... Wait, I know how to contact Jindan Zhenren and the others."

Thinking of this, Lin Ji suddenly stopped, and Xiao Ningxue, who was hugging his arm, also stopped.

"What's wrong, senior brother?"

"Ningxue, I need to use the teleportation array to return to Xuantian City, quickly!"

Xiao Ningxue was very obedient. She immediately took Lin Ji to the location of the teleportation array and asked Lin Ji to stand inside and prepare to start it.

"Brother, the control talisman of Xuantian City's teleportation array is in Youran's hands. Come back soon."

"Ok."

The teleportation array was activated, Lin Ji waved goodbye and disappeared in Tianshu City. After seeing him leave, Xiao Ningxue returned to her room to practice.

……

Moon surface.

A flash of sword light appeared, leaving a sword mark thousands of miles long. Two figures appeared one above and one below. Pu Jianxing floated above and looked at Ye Xun's body, which was unharmed except for his clothes, with a solemn expression.

After fighting for so long, the moon was already badly damaged in the aftermath of the fight, but the two men were still in good condition except for their clothes. Pu Jianxing was very puzzled.

"This Ye Xun must have just broken through to the Golden Core stage not long ago. His body is really abnormal, much stronger than a veteran Golden Core like me. My attacks are completely useless to him. And because of that strange attraction, I was also hit and injured several times. Although I recovered immediately, it already shows that I am at a disadvantage."

Thinking this, Pu Jianxing continued his attack, not wanting to give up. Ye Xun also came forward again. With a thought, a huge gravitational force deflected Pu Jianxing's attack and sucked him in front of Ye Xun.

A hand stabbed into Pu Jianxing's chest, but no blood flowed out. Pu Jianxing ignored the wound on his chest and slashed at Ye Xun's neck with a sword. The sharp sword energy passed through his body and left a sword mark on the back, and then blasted Ye Xun into the surface of the moon, leaving a deep pit with a diameter of a thousand miles, but it was useless. In an instant, Ye Xun left the deep pit and returned to the air, and Pu Jianxing's wound had healed.

"Master Pu, there will be no result if we continue to fight like this, so let's stop now."

"The way you cultivate to the Golden Core is different from the current cultivation world, right? I can feel that your body is constantly absorbing the surrounding spiritual energy and constantly compressing it inwards, so the strength of your body is so outrageous. Was it developed by True Lord Yu Shui?"

Pu Jianxing did not respond to Ye Xun's words, but asked his own questions.

"Yes, the True Lord did research a new golden elixir technique, and I am the first one to practice it."

"That's what I think. Let's continue."

Pu Jianxing slowly closed his eyes, and a world emerged behind him and began to invade the surrounding space. Seeing this, Ye Xun shot out a beam of five-colored light, hoping to interrupt Pu Jianxing's moves.

"Sword World!"

Pu Jianxing's eyes opened and turned silver-white, rapidly invading the surrounding space, while Ye Xun's attack passed through his body and could not hit him, as if the opponent was not in this space. Instead, he created a bottomless pit on the moon.

Finally, a complete world was formed, bringing Ye Xun into it. This world was like Kaiyang Star, with mountains, rivers, flowers and trees. It looked peaceful and harmonious, but Ye Xun felt that this world was full of murderous intent. Everything in this world gave him the idea that it was a sword, and his body was very heavy, as if the whole world was pressing on him, making him unable to move.

At this time Pu Jianxing appeared high in the sky, looking down at Ye Xun below, his silver-white eyes staring at him mercilessly. He stretched out a hand, and all the sword energy in the sword world gathered in his hand, and finally an ancient long sword appeared. The moment it appeared, Ye Xun felt the danger. He knew that the sword was the sword rule embodied by Pu Jianxing, but he could only watch and could not do anything.

"The Rule of the Sword: One Sword Separates Worlds."
