"And?"

Han Yu looked at the mouth of the earth's fire, and the behavior of the black pupil was obviously saying that the fire vein stones in the ground had not been exhausted. Pen, fun, pavilion www. biquge。 info

Just the fist-sized fire vein stone just now, the price was at least more than three thousand spirit stones, and if there were more fire vein stones underground, Han Yu would have made a windfall.

Since the Spirit Beast Mountain Fire Room was built, I don't know how many monks have come to this Earth Fire Room, but none of them have found this Fire Vein Stone, I have to say that Han Yu's luck is extremely good.

Soon, the black pupil used his head to retrieve a fire vein stone about the same size as just now, and then, without waiting for Han Yu's command, he once again drilled into the mouth of the earth's fire.

"It seems that there are a lot of fire gangue reserves in this underground......

Han Yu was naturally happy to see this situation, if he collected enough Fire Vein Stones, then after he entered the Dan Period, he would not even have to save the effort of finding spiritual materials.

Time is fleeting, and in the blink of an eye, half an hour has passed.

During this time, Hei Tong went back and forth more than ten times, and the fire vein stones transported back were piled up in a small pile, and just now, Black Pupil brought back a fire vein stone the size of a baby's head, which surprised Han Yu.

If it weren't for the fact that the storage bag couldn't withstand the high temperature of the fire, Han Yu really wanted the black pupil to go down with the storage bag and take back all the fire vein stones in one go.

Now that the black pupil was still on the way back and forth, Han Yu couldn't help but look forward to how much the underground fire gangue reserves would be.

"Roar~"

Just when Han Yu was full of anticipation, there was a sudden low muffled sound underground, like a giant beast roaring.

"What's going on?"

Han Yu stared at the mouth of the earth fire in disbelief, just now, he clearly saw that the originally burning earth fire was briefly extinguished for a moment.

"Whoosh!"

The figure of the black pupil quickly rushed out of the mouth of the earthfire, and this time, it did not bring back the fire vein stone.

Han Yu untied the scale armor on the black pupil's body, and saw that the black pupil quickly wrapped around Han Yu's arm, and his body trembled.

Han Yu could clearly feel the fear in Hei Pupil's heart, this situation, even when he faced the rock bone rat, had never appeared.

No matter how confused Han Yu was, there was still an insurmountable communication barrier between Han Yu and Black Hitomi, and there was no way to know what had happened to him.

And the roar similar to that of a giant beast just now fell silent after appearing once, and the atmosphere was unusually calm, as if nothing had happened.

In the aisle outside, no monk came out to inquire. If it weren't for Han Yu seeing the frightened appearance of the black pupil with his own eyes, he would have thought that the sound just now was just the collapse of the earth fire tunnel underneath.

After some serious consideration, Han Yu still decided to continue to stay in the Earth Fire Room to refine the weapon, the Spirit Beast Mountain has been established here for so many years, and nothing has happened, presumably the existence that roared just now may just be a spirit beast raised by a certain big man in the Spirit Beast Mountain.

As for the beast's roar just now, it was just a warning.

Of course, this is just Han Yu's wishful thinking, if something really happens, there will also be the Yuan Infant Monk of Spirit Beast Mountain on his back, and Han Yu only needs to take care of his life when he arrives.

Thinking of this, Han Yu received the black pupil into the Poke Ball, and in its current state, it was impossible to refine the Ice Fat Pill anymore.

After picking up a few materials from the ground, Han Yu calmed down and threw himself into the refining process again.

......

Time flies, in the blink of an eye, half a month has passed, during this period, except for sleeping every three days, Han Yu spent almost all of his time refining and cultivating, and the previous beast roar never appeared again.

In half a month, the four phoenix blood flowers of nearly a hundred years obtained from Gu Jing have all been refined by Han Yu, coupled with the improvement of Han Yu's cultivation for a long time, now Han Yu has reached the peak of the early stage of foundation building, and he is only one step away from the middle stage of foundation building.

In terms of refining, Han Yu has also made great progress, although at the beginning, refining new mid-level magic weapons frequently failed, but in the last seven days, Han Yu seems to have mastered a certain law, and with the assistance of the live broadcast system, the success rate of refining new mid-level magic weapons is as high as 80%.

In this way, it didn't take Han Yu a few days to successfully pile up his proficiency and break through to the ranks of senior refiners.

After reaching the Advanced Refiner, Han Yu's refining speed slowed down, not because of the lack of materials, but because Han Yu had encountered a bottleneck.

The new high-level magic weapon, no matter how Han Yu changed the refining method, did not succeed in refining, and the fifty percent success rate of the live broadcast system seemed to have disappeared, and it had no effect.

In desperation, Han Yu could only choose the ordinary high-grade flying sword recorded in the refining classics.

This time it was very smooth, Han Yu only refined it once, and he successfully refined an ordinary fire attribute high-level flying sword, increasing the proficiency of the senior refiner a little.

"What went wrong?" Looking at the large pile of waste refining materials on the ground, Han Yu frowned, he had to find a way to solve this problem, just by refining ordinary high-grade magic weapons, the improvement of proficiency little by little was too slow.

As for refining ordinary top-level magic weapons, not to mention the low success rate, all kinds of ore materials are even more expensive, with Han Yu's current net worth, without selling the fire vein stone, it is estimated that he will already go bankrupt before he has advanced to the refining master.

Even with the assistance of the live broadcast system, only a 10% refining success increase rate is not enough to form a good buying and selling cycle.

In the next few days, Han Yu tried again and again, until he exhausted all the materials for refining high-grade magic weapons, but he did not succeed in refining a new high-level magic weapon.

Han Yu had to face this cruel reality, if he wanted to advance to the refining master, it would not be possible to fail like this.

Even if the speed was slower, Han Yu would have to step into the ranks of refining masters by refining ordinary high-level magic weapons.

After deciding, Han Yu cleaned up all the materials in the ground fire room and put them in a storage bag, after all, he was going to Zhaohua Peak's Fang City, and Han Yu was not at ease to leave this pile of things in the empty earth fire room.
