After putting away the beast's teeth, the mechanism in the cave was exposed to Yun Sumo's eyes at the same time.

What left her speechless was that the mechanism was hidden in a bird's beak. He was very skeptical that the master of the secret realm, that is, the great power from 10,000 years ago, had any special habits.

She heard the sound of water dripping in the cave just now, and sure enough, when she came out, she saw water dripping down the moss-covered stone wall.

Although the water was dripping slowly, the black stone on the ground was dripping straight out of a hole the size of a bucket.

However, this is not the most important thing. The most important thing is that the black stone, which turned out to be a black sky stone. Compared to the Black Sky Stone she got in the past, the Black Sky Stone is dozens or hundreds of times larger than the total!

"Damn, I'm not dreaming!"

Yun Sumo was already enthusiastic, such a large piece of black sky stone, if she hadn't come to the secret realm, she didn't know how long she would have to toss outside to collect it.

It's still a little far from the ultimate goal, but it's already a big step closer!

Looking at the hole dripping out of the black empty stone, she was a little puzzled. It stands to reason that even if the Black Sky Stone is a space stone, even if it is dripped for tens of thousands of years, it is impossible for it to be dripped out of the hole by water.

Could it be that there is something wrong with this water?

Just when she reached out and touched the water droplets, a golden light suddenly appeared in front of her, and a line of subtitles appeared: Successfully refine a hundred spiritual weapons, take the materials by yourself, and complete them within twenty-four hours, so that you can get what you want.

After the subtitles were displayed, only a pile of refining materials remained. And the huge black sky stone and water droplets disappeared at the same time, and Yun Sumo searched for several turns but did not find any trace.

She covered her heart and was heartbroken, regretting that she had not done it at the beginning. Why didn't she accept the Black Sky Stone as soon as possible, now she still had to refine a hundred spiritual weapons in two days to get the Black Sky Stone.

One hundred pieces in two days, and the average refining time for each spiritual weapon was only less than half an hour. And with her current cultivation, the normal time to refine a spiritual weapon is not less than half an hour, that is, no less than an hour.

"Damn!"

After cursing, she hurriedly dug out a refining furnace from the pile of refining materials, pinched it with one hand, and started to dry.

Fortunately, the refining furnace and equipment are powerful, and they can all refine high-grade spiritual weapons. However, Yun Sumo has not yet broken through to the advanced refiner, and can only refine intermediate spiritual weapons.

The free equipment doesn't have to be used in vain, just so she uses it to build a hundred intermediate spirit swords, and when the team is formed, she can give them directly.

Thinking of this, her heart instantly calmed down, and even a hundred tasks had been forgotten. Completely calm down and immerse yourself in the refiner.

Yun Sumo didn't notice it, and just as she sank down, the aura in the stone cave fluctuated instantly.

There is no time for cultivation, and there is no time for refining. Yun Sumo didn't listen to anything outside the window, and the whole person was immersed in the refining vessel.

And her refining speed is also getting faster and faster, more and more stable. From one piece in the first half an hour to three pieces in an hour. In the end, it reached three pieces in half an hour.

This speed was something she had never dared to think of before, but she was immersed in the refining weapon and did not notice it at all.

When the twenty-four hours were over, she woke up, and the ground was already full of intermediate spirit swords.

"Whew, it's finally finished. Fortunately, the old lady is smart and can refine the two together. ”

If someone hears what she says, their jaws will drop. Refining two spiritual weapons at a time is an unprecedented thing, and even a high-level refiner has never reached this realm.

Yun Sumo didn't care about this, she was busy counting the spirit swords piled up on the ground: "One, two, three, four...... Wow, there are so many!"
