The loose rocks are all included in the system space, anyway, the same matter only temporarily uses one square space, and Lei Dong is not worried about the space will be insufficient at all.

About half an hour later, the cave that Lei Dong had dug was already three meters deep, but Lei Dong felt that such a distance still made him feel insecure, and he had to dig deeper, at least he felt that it had to be 100 meters to be considered safe.

"Ding!"

The Xin Jin Sword inserted into the rock and made a faint sound, and the frightened thunder immediately did not dare to move again, and after waiting for a long time to see that there was no movement, he slowly began to draw the Xin Jin Sword again.

Lei Dong knew that Xin Jinjian must have encountered some foreign object, otherwise this red rock would not make Xin Jinjian make any sound at all.

At the same time, Lei Tong also knew that if he could make a soft sound from the Xin Jin Sword, it would mean that the foreign object itself was also very hard, at least no less than the Xin Jin Sword itself.

What does this mean?

It shows that the foreign object is definitely a spiritual material! At least it must be higher than the ore of the lower grade of the Yellow Rank, because the Xin Jin Sword can pierce through the hard meteorite ore.

"It's really not that I'm greedy, the spiritual materials and spiritual things sent by God, if you don't take it, you will be punished by God!"

Lei Dong said secretly in his heart, and then slowly cleared the rocks around the unknown spiritual materials, and a red half-crystal the size of a human head appeared in front of Lei Dong's eyes, and without saying a word, he directly put it into the system space.

Pyrometrist: Yellow-rank high-grade fire ore.

"I'll go, the Haotian Realm is really full of heavenly treasures, this, the Tianwu Sect really didn't deceive us!"

Lei Dong secretly said in his heart, this was the first time he had seen a high-grade spiritual material on the Yellow Order, and it was such a big piece. Directly refined, the fire crystal ore becomes a fire crystal ingot +16.

"The spiritual material content in the ore is quite high!"

After Lei Dong said with emotion, he continued to dig holes, and at the same time, because of the joy in his heart, he adapted the newspaper song of his previous life into the song of the miners, and sang silently in his heart: lalala...... Lalala...... I'm a little connoisseur of mining, left and right, and another piece of ore has arrived......

Sure enough, Lei Dong dug out another piece of ore, although this piece of pyrotechnic ore was only the size of a fist, but it still stimulated Lei Dong's enthusiasm to dig holes.

Two hours later, the cave that Lei Dong had dug was already ten meters deep, and the fire crystal ingots in his synthesis space had reached as many as 86 ingots, and at the same time, there was an extra thumb-sized fire origin crystal.

Crystallization of the origin of fire: a treasure of heaven and earth, containing the innate fire qi.

Lei Dong had obtained a piece of Gold Origin Crystal before, but he didn't know what it was used for at the time.

At this time, Lei Dong is no longer the Wuxia Ameng of the past, he has memorized the heavenly and earthly treasures, spiritual materials and spiritual objects issued by the Tianwu Sect.

Knowing that this origin crystallization belongs to the top celestial material, it has a wide range of uses and is extremely precious, and it can be used to refine high-level spiritual treasures, and can also be used to forge high-level divine armor, and it can also be used to arrange formations and draw formation runes.

It's N times more precious than the Soul Eater Wood, because the Soul Eater Wood is only a boutique in the earth treasure, and the difference between the two is one level.

The appearance of this fire origin crystallization has stimulated the enthusiasm of Lei Dong mining even more, at this time he has long ceased to dig holes for the purpose, but for the purpose of mining, anyway, it seems that this is a matter of no delay.

Half a month has passed in a flash, and the mine hole dug by Lei Dong has been nearly a thousand meters long, and it is still a zigzag kind. Because the farther away from that high-level demon beast, the speed of Lei Dong's excavation increased, and even later, Lei Dong used the power of Jin Yuan to bless.

If you're hungry, eat Bigudan!

If you are thirsty, there is a mountain spring prepared!

When you're tired, sit down and rest!

If you're sleepy, get out of bed and go to sleep!

It's easy to do, it's to go back to Yuan Dando, and it doesn't matter if you can't get back ten pieces, then come back with ten more!

Half a month ago, Lei Dong was excited, and half a month later, Lei Dong was already numb, just because in his synthesis space: Fire Crystal Ingot +3562, Fire Origin Crystal (Complete) +38, Fire Marrow Ingot +126.

The origin of fire crystals, after the lightning digs a certain amount, is automatically synthesized into a complete form by the system.

At this point, Lei Dong knew that the complete form of the origin crystallization was the same as the shape of the Yuan Stone, but the volume was twice that of the Yuan Stone. And the fist-sized piece of gold origin crystallization he got before was just a large fragment.

Fire Essence Ore: Xuanjie mid-grade fire ore.

This is the new ore that Ray came across after digging for a few days, and it also excited him for two days when he first got it. Xuanjie ore, can you not be excited?

But later, after Lei Dong dug out a lot of pieces one after another, he was relieved, although the forging material was good, it seemed that he couldn't use it for a while, so he could only put it in the synthesis space as a decoration.

At this time, Lei Dong is no longer ready to continue digging, and now he plans to dig a space within a radius of about 100 meters to use it as a martial arts arena at his location, and he plans to wait for the end of the Haotian Realm while cultivating here.

Time flies, and Lei Dong doesn't know how long it has been, anyway, he feels that he has to have a few months. Because he basically mastered those synthetic martial arts and upgraded martial arts.

The only thing that has not been cultivated is the Yuan Force, but this is where the thunder is located, the power of the Fire Yuan is too expensive, and the other four systems of Yuan Force are too weak.

As long as Lei Dong cultivates the Yuan Force, the five elements in his body will be out of balance, and if he uses the Five Elements Transformation Method, he will waste a lot of time, so it is better to use all this time to cultivate martial arts.

There is always a reward for paying, at this time, the thunderous forging realm has reached the peak state of the mortal-level Great Perfection realm, and the strength of the body has reached 9.9 Ox, as long as the yuan force in his body keeps up, he can launch an impact on the yellow level.

But at this time, Lei Dong had to give up his plan to continue hiding until the Haotian Realm was closed. Because, the mountain spring water he had stored was almost exhausted by him.

It's been a few months, and the Haotian Realm hasn't ended yet, which is a result that Lei Dong didn't expect at all.

"Damn, why hasn't this Haotian Realm been closed yet, and when I came in, the Heavenly Martial Sect didn't say that it had been so long, so I would have stocked up on more spring water!"

Lei Dong complained in his heart, but his hands still didn't stop moving, at this time he was no longer forging his body, he was digging a hole again, but this time he was digging upwards.

If a warrior does not reach the realm, he will not be able to truly open the valley, and he must eat and drink.

It was another few days, and when Lei Dong drew his sword back and saw a glimmer of light, he finally saw the light of day again.

Lei Dong released all his senses, and after sensing that there was no danger outside, he quickly dug open the exit and drilled out.
