The Celestial Crystal Star is a large celestial body in the Aeolian Realm, just because the Celestial Crystal Star is covered with ice and snow all year round, and the temperature is low and cold, which exceeds the minimum limit that flesh and blood creatures can bear, so that this planet is rarely visited by human beings and other flesh and blood lifeforms, or go to experience.

Under the thick ice layer on the Celestial Crystal Star, there are abundant resources, and there are also various dangers, because in the depths of the underground space, there are ice and snow monsters with extremely strong and terrifying combat effectiveness, which makes human beings and other creatures rarely set foot in the Celestial Crystal Star and fight the idea of resources on the Celestial Crystal Star.

"Whoosh!"

A figure slashed through the void at great speed, penetrating the atmospheric defenses of the Celestial Crystal Star, and landed on the Celestial Crystal Star, which was covered with a thick layer of ice.

The person who stepped on the Celestial Crystal Star was none other than Long Fei.

Long Fei set foot in the Celestial Crystal Star for two purposes: first, to refine the star core of this planet, and second, to explore whether the underground space of the Celestial Crystal Star could find a vein rich in the power of the Heavenly Vein, for him to practice the Heavenly Vein Treasure Body.

"I hope this trip to the Crystal Star will not disappoint me. After stepping on the Celestial Crystal Star, Long Fei glanced around, but he didn't notice how much the cold environment here had affected him, and he didn't even notice any discomfort.

Perhaps because in Long Fei's opinion, time seemed a little nervous to him, and after he arrived at the Celestial Crystal Star, he only stood in place for ten seconds, and immediately cast a retreat technique, burrowed into the underground space, and went directly to the location of the star core in the depths of the planet.

When he went deep into the ground and reached a depth of 10,000 miles, Long Fei sensed the existence of some pressure, but because his defense was super perverted, he could easily withstand it and carry it.

Of course, if a monk of the same system level as him came to the depth of space where he was at the moment, not to mention being frozen into an ice sculpture, he would at least be frozen to stiffness and lose his combat effectiveness.

"This is only a third of the depth of the underground space, and the oppressive force is so strong, with my defense, it seems that I want to get close to the star core, which seems to be a little unrealistic. Sensing that the oppressive force was getting stronger and stronger, a faint look of shock appeared on Long Fei's face.

However, he did not mean to back down, and continued to keep moving at a uniform speed, rushing to the deepest part of the underground space.

After about five thousand miles deeper, the underground space suddenly trembled violently, and then Long Fei clearly saw that a snow-white figure was traveling through the underground space at a very fast speed, galloping towards his location.

The ice and snow monster is huge, and when it moves in the underground space, a large number of ice crystals, earth and rocks are directly impacted to form an undercurrent with amazing lethality, and pounce on Long Fei's location.

Long Fei's defense was strong, but under the impact of the undercurrent of earth, rocks and ice crystals, he still couldn't stabilize his body, and he was directly impacted and flew out upside down, surging along the undercurrent, and pounced into the distance.

"I didn't even see what the ice monster looked like, and it was rushed away by the power it created, it seems that the combat power of this ice monster must have surpassed the 7th and 8th level monks of the Chaos Realm. With my current system level, dealing with it can only be passively beaten, but nothing is gained. I heard that in the underground space of this Celestial Crystal Star, there are many ice and snow monsters with such strength. That is to say, if you want to refine the star core of this planet, or use the Celestial Crystal Vein in the depths of the planet to practice the Heavenly Vein Treasure Body, it seems that the only way to get your wish is to get rid of all the ice monsters that are in the way. In that case, let's just raise the system level. ”

After drifting with the tide and being shocked about thirty miles away from his target, Long Fei knew that it was simply unrealistic to continue to deal with the ice and snow monsters on this planet with the current system level, so he did not hesitate any longer, and immediately exchanged all the spiritual points accumulated in the recent period into experience points to upgrade the system level.

The efficiency of the system, that is not to say, Long Fei only needs one thought, give an order, the system almost in the blink of an eye, to complete the instructions issued by Long Fei, the accumulated spiritual points, into upgrade experience points, and his system level, from the previous level 111, to the current level of 116.

That is to say, Long Fei directly increased 5 system levels this time, which made his combat effectiveness improve by leaps and bounds, even if he was a master at the top level of the Chaos Realm, fighting with him, if he was not careful, he might be killed by him with one blow of the "Dragon Fist" technique.

As the level of the system increased, the power that rushed towards him could no longer shake his body and wash over him, like a gentle breeze.

Soon, the Ice Monster, which had created a powerful and powerful Ice Monster, finally revealed its true face.

The Ice and Snow Monster is three feet tall, and its overall appearance looks like a bat, but the whole body is crystal blue, just like a glass product.

The Ice Monster's eyes glowed with a faint red sheen, like two red gems set in its head.

If the Ice Monster were standing still, no one would think of it as an alternate lifeform, but as just a crystal statue.

"Whoosh!"

Long Fei dodged out, approaching the ice monster at lightning speed, and before it could react, Long Fei's fist carried a powerful attack force and smashed into the ice monster's head.

"Bang!"

The ice monster, which is amazingly powerful in combat, was actually shot in the head by Long Fei's punch, and then its huge body, directly under the impact of the power that poured out of the fist, quickly collapsed, turned into ice crystal particles and floated there, and then a faint blue light, which looked like a sapphire crystal, appeared in Long Fei's sight.

The moment the blue crystal appeared, Long Fei clearly captured a trace of the power of the Heavenly Vein, which escaped from the crystal, and his heart was suddenly overjoyed: "The crystal contained in the body of this ice and snow monster actually contains such a strong power of the Heavenly Vein. From this, it can be seen that on this Celestial Crystal Star, there must be a very amazing storage of Celestial Vein Ore Source. ”

His right hand reached out, released a force, took the crystal containing the power of the heavenly veins in the palm of his hand, stroked it gently, and then put it away and threw it into the system backpack space, and then quickly set off, rushing directly to the deeper part of the underground space of the Tianjing Star.

The further he walked into the depths of the underground space, the more and more ice and snow monsters Long Fei encountered, if it weren't for his strong combat power, and his defensive power was enough to easily withstand the strong attacks of the first-level cultivators of the Qiankun Realm, then he would not be able to move an inch, and if he wanted to get close to the Celestial Crystal Star Core, it would not be so realistic at all.

In the next 10,000 miles, it took Long Fei a full month to complete the journey, and the number of ice and snow monsters killed by him reached tens of thousands, as for the accumulated spiritual value points, it was 83,360 trillion points, and the number of crystals containing the power of the rich heavenly veins obtained was as many as 13,724.

As for the power of the Heavenly Veins contained in these crystals, it is unknown whether Long Fei can cultivate the Heavenly Vein Treasure Body exercises to the full level.
