Lin Xiao was stunned and stood there like a wood, and exclaimed in his heart: "Immortal Crystal!" When he left Lingxiao Sect, Zhenren Mingxin gave him some tips on the knowledge about spiritual crystals. Spiritual crystals are divided into four types: low-grade, medium-grade, top-grade and top-grade. Among them, low-grade and medium-grade are more common, and top-grade and top-grade are extremely rare.

In the spiritual crystal mine, sometimes highly condensed rich ores appear. After countless years of condensation, there is a certain chance that the extremely rare immortal crystal in the cultivation world will be born. The probability of this is extremely small and pitiful. It is said that these two spiritual crystal mines have only produced immortal crystals once. That time it was also found in this mine, so more people come here than those who go to the Martial Arts Sect.

Lin Xiao's saliva flowed down. The lowest-quality spiritual crystals of this nest are the top-grade spiritual crystals. The spiritual crystals around the central immortal crystals are even between the top-grade spiritual crystals and the immortal crystals, which can be called pseudo-immortal crystals. The micro-conscious mind spread out surgingly and cautiously, and they have been exploring for a long distance before they are satisfied. Then they set up a few formations and then they start mining with confidence.

Even so, he did not intend to extract the spirit crystals exposed, but collected the surrounding rocks together. In this way, the rocks wrapped around the spirit crystals, which were inconspicuous and would not attract attention due to the energy fluctuations when opening the stone wall. Although there was no one around, it was always better to be careful. After picking them, it would be better to find a safe place and then pick the spirit crystals inside.

The innate spiral sword energy easily cut a huge stone ball with a diameter of more than one meter. Lin Xiao happily added the stone ball to the dragon ring and hummed a little tune happily. This time he made a fortune, the fairy crystal. It contains a fairy spirit energy that is more advanced than spiritual energy. If it is absorbed, wouldn’t it be beautiful!

After removing the formation and retracting the microscope, Lin Xiao wandered around to look for mines elsewhere. He remembered that mining on the earth was mined by machines, pulling out one by one. But here, mining was definitely a test of patience and caution. Some people had not mined one for two or three years, and if they had no patience, they could only admit that they had lost the top-grade spiritual crystal that was exchanged for the mining token. And while mining, they had to be careful of attacks, otherwise they would not know when their lives would be lost.

After staying in the mine for five years, Lin Xiao got 37 top-grade spirit crystals and 19 top-grade spirit crystals. Don’t think that this number is very small. Some people haven’t got three or five of them for more than ten years. These spirit crystals are barely enough, so Lin Xiao plans to leave.

A palm appeared strangely from behind him and slapped heavily on his back. Lin Xiao was hit by this sudden palm, and blood spurted wildly. Before he could land, dark Gemini armor appeared on his body, and at the same time, the volley of the Sword and the Breaking Cloud Sword flew out of the body to defend. He knew that the man was also injured. Because just when he was hit, the innate sword spirit quickly shot out two sword energy and shot into the body of the sneak attacker.

His microscopic consciousness quickly covered the surroundings, and an old man in black robe appeared in his sight. Ying'er leaned into his ear and said, "This person actually has the same aura as me. It seems that he can suddenly appear with this ability."

Lin Xiao unceremoniously controlled the volley of the Sword and the Breaking Cloud Sword and shot at the old man. He did not ask the old man's name or other nonsense. It must have been smashed by the Fairy Sect, and of course the purpose was to seize the spirit crystal in his hand. Therefore, he had to kill him while the innate light and dark spiral sword energy was raging in his body.

However, the old man was very strong, and there was not much innate spiral sword energy that invaded his body, so he could still keep moving. The sword Lin Xiao's two swords shot and quickly dodged away. Lin Xiao was frantically approaching his body, and shot dozens of innate light and dark spiral sword energy with his hands. He was very angry. Although the old man had suspected space-based magic weapon to suddenly attack, he also knew that he was indeed a little careless before.

The old man shouted and actually forced out the spiral sword energy of the innate light. However, he let out a muffled groan and spit out blood. Lin Xiao was immediately overjoyed. Is my sword energy so easy to deal with? Even if you force it out, you have to get some injuries. The Lingkong sword energy and the Poyun sword energy are powerful, and the mine channel is flew everywhere by the gravel shot by two sword energy.

Suddenly, the old man's figure disappeared in an instant, and Lin Xiao's sword energy suddenly fell into vain. Just when Lin Xiao was surprised and suspicious, Ying'er squeaked and teleported out. Lin Xiao heard a muffled groan and an old voice again: "How is this possible!" At the same time, the old man also showed his figure.

Lin Xiao immediately knew what was going on and secretly shouted "Good job"! The Lingkong Sword and the Poyun Sword rolled towards the old man with a sharp sword light. The old man immediately sacrificed a magic weapon, and a huge ball of flame appeared instantly, pounced towards Lin Xiao frantically. The water-based golden elixir in Lin Xiao's house moved, and a cold air burst out. A huge ice shield that was one foot thick appeared in front of him, blocking the flames.

The old man retreated quickly and his figure disappeared again. Ying'er snorted coldly and disappeared at the same time. The old man was forced to appear again. The old man who showed up simply stopped retreating and no longer disappeared. He shouted angrily and put on a pair of fist gloves with both hands. The blazing flames burned on the fist gloves, and he swung his fist at Lin Xiao.

Lin Xiao smashed an ice flame divine thunder. The old man actually flew wildly and hit the ice flame divine thunder! Lin Xiao was stunned and scolded him for being idiot in his heart. The old man was purely looking for death. The ice flame divine thunder exploded, and the old man was blown backwards. His body hit the stone wall of the mine, and half of his body was covered with frost.

"Ice Flame Divine Thunder!" He shouted incrediblely. Lin Xiao didn't say anything, and then attacked hard. The old man shook his right arm, and the flames suddenly became violent on his body. The covered frost suddenly shook and the flames rose again. Lin Xiao's figure stopped quickly. This old man had such a powerful cultivation level. Ice Flame Divine Thunder didn't take it seriously!

The Lingkong Sword and the Breaking Cloud Sword shot out from the old man's feet with dozens of sharp sword energy. The huge power of the Breaking Cloud Sword appeared at this time, easily breaking the old man's defense and smashing his left arm. The old man roared angrily but still advanced instead of retreating, smashing the ice shield with one punch, hitting Lin Xiao's armor heavily.

A huge force came, and Lin Xiao was knocked out immediately. As the blood was vomiting wildly, he felt the pain in his body as if it was burned by fire. Damn, why is this old man's fist so powerful? The ice shield condensed by me can defend against top-grade spiritual weapons, but he was so easily broken.

The Breaking Sword made a contribution with one sword, and Lin Xiao directed it to attack again. The old man seemed to be addicted to smashing his fist, and he waved his fist to meet him without hesitation. Ding! The harsh sound waves stirred up. Lin Xiao's chin almost fell off, wow! The gloves on this old man must be a good thing!
