In the following time, Su Shen and Gangyan almost turned over the cave. All the dung masses left by the gold-eating insects in the pen "Fun" Pavilion www.biquge.info were found, and then broken one by one, and sure enough, every few pieces could be found.

Half a day later, almost all the dung masses had been knocked out, and after making sure that there was no complete piece of insect droppings, the two stopped. At this time, the Star Silver Essence in Su Shen's hand had grown from the size of a projectile to the size of a baby's head.

The star silver essence the size of a baby's head, seeing so much, Su Shen was also drunk.

You must know that outside, a piece of star silver essence the size of a walnut can be sold for more than five thousand lower-grade source stones. With this piece in Su Shen's hand, there is no problem in rubbing out thirty or forty walnuts, that is, the value of more than 200,000 yuan.

"I really didn't expect you to be a money-making machine. Su Shen looked back at the gold eater that was still sleeping, and sighed in admiration.

The refining of Star Silver Essence is a very complex process, and the consumption is also large, and the refining ratio is almost forty to one, which causes the value of Star Silver Essence to remain high.

Su Shen didn't know how much gold-eating insects were consumed, but he at least knew how much gold-eating insects needed to eat every day.

Gold-eating insects have a great appetite, and can eat about thirty catties of metal ore every day, and the star silver content here is almost five percent, that is, they swallow about one and a half catties of star silver every day. Judging from Ulrique's notes, he has been here for about two hundred and seventy days, that is, he has devoured about four hundred catties of star silver. And the star silver essence that Su Shen obtained, don't look at it is only the size of a baby's head, but it weighs about twenty catties. That is, a conversion rate of almost twenty to one, which is much higher than forty to one.

Of course, this is only an approximation, and it is not certain. What if the gold eater just started eating a particularly high content of star silver ore?

The reason why Su Shen discovered the essence of star silver this time was because he had fed this big guy four pieces of purified star silver before, not star silver ore, and the star silver provided by these four pieces alone was more than the normal daily intake of star silver by gold eaters. The result was that the gold-eating insect pulled out a particularly large piece of essence, which would be discovered by Su Shen. Otherwise, Su Shen would probably be like Ulrik, ignoring the treasure buried under the dung.

In other words, if you feed the purified Star Silver directly, you are likely to get more Star Silver Essence and can calculate the conversion ratio more accurately.

Su pondered.

In the following days, the quality of life of the gold-eating insects improved significantly.

Su Shen asked Gangyan to feed the gold worm pure star silver directly, and calculate the weight before each feeding.

The treatment of the big insect has improved, and he is so happy that he shakes his head and tail, and his attitude towards Gangyan is simply to the point of flattery.

However, after waiting for three days in a row, Su Shen didn't wait for the gold-eating insects to be excreted, and even his appetite began to decline.

This made Su Shen a little strange.

On the fourth day, the gold-eating insect became more and more unenergetic, and it didn't even eat what Gangyan fed it, but just sniffed it a few times and walked away.

Su Shen began to worry about whether he had done something wrong.

That night, the gold-eating insects began to exert their strength in the corner.

It groaned in pain, hummed and chirped, and kept rubbing against the mountain wall, grinding the mountain rocks to pieces, but it just couldn't excrete.

Seeing this scene, Su Shen finally understood.

"It's bad, it's constipated. ”

Steelstone: "......"

That night, the gold-eating insects tossed around for half the night, and finally pulled out a big silver shiny ball.

Take it and weigh it, good guy, four and a half catties - Gangyan threw half of Su Shen's star silver inventory to it to eat.

No wonder it can't pull it out.

This experiment made Su Shen understand two things. One: The actual conversion ratio of gold-eating insects is about twenty-two to one, which is a little lower than previously judged, but not much. Two: Everything is too much.

The gold-eating insects that can't be killed by the ink-patterned war knife and the moon-swallowing wolf knife can almost be suffocated to death by, and it can only be said that the world is really wonderful.

From this day on, Su Shen resumed his normal diet for the gold-eating insects, only a small amount of pure star silver was mixed with them, and his diet returned to normal, and the spirit of the gold-eating insects quickly improved.

In his spare time, Su Shen will also think. Gold-eating insects can pull out the essence of star silver by devouring star silver, so will swallowing other metals also condense essence?

This can only be tested in the future.

Now the urgent task of the afternoon is how to take away this money-making machine.

Fortunately, Ulrik left behind a method of controlling the gold-eating insects, a kind of enslavement scroll, which can create a fixed impression in the target's mind that this is my master, and can understand and carry out instructions to a certain extent.

The Slavery Scroll was not difficult to learn, and Su Shen quickly mastered it.

On the eleventh day of entering the mine, all the star silver mines in the belly of the mountain were finally dug up.

Su Shen had also roughly understood Ulrik's experimental experience, and there was no need to stay here.

Before leaving, Su Shen first took out a blank source power scroll, which was a scroll made of fierce beast skin, and after making an enslavement sigil on it, it could be used against gold-eating insects, which was exclusive to ancient arcane.

As for people nowadays, they usually use the simpler and more convenient source power rune paper. The source power rune paper is made of special paper that can carry the source force, and the advantage is that it is low cost and can be mass-produced, but the effect is worse than that of a scroll, and the storage performance is not very good.

As soon as the slave scroll landed on the gold-eating worm, it slammed into ashes.

Slavery resistance.

Powerful beings will resist the enslavement scroll, and the greater the difference in strength, the more difficult it will be to succeed. Su Shen's strength was not comparable to that of the gold-eating worm, so his slavery scroll shattered in one fell swoop.

Su Shen was not convinced, and made two more slavery scrolls, but both of them met with resistance.

This made Su Shen feel helpless.

There weren't many blank source power scrolls left behind by Ulrik, there were only four in total, three failed, and the last one remained.

Looking at this last slavery scroll, Su Shen hesitated for a moment.

If this one fails again, you may not have a chance to accept it.

At that moment, Gangyan suddenly said, "Let me try, okay? ”

"You?" said Sue. was stunned.

Gangyan trembled a little nervously: "Please don't get me wrong, my master, I don't mean to grab pets with you." I just thought, maybe it will listen to me. ”

Su Shen looked at Gangyan, and then smiled: "No, I don't mind...... Maybe you're right. ”

Giving the slavery scroll in his hand to Gangyan, Su Shen said, "Come on." ”

Gangyan took the scroll and looked at Su Shen slowly: "You know, master." If I succeed, it ...... Just listen to me. ”

"Of course, it doesn't matter. Go for it, Steelrock. Su Shen patted him.

The steel rock took a breath and walked over, placing the enslavement scroll on the back of the gold-eating worm.

In terms of strength, Gangyan is much lower than Su Shen.

But at that moment, the slavery scroll was not burned.

The gold-eating insect raised its head to look at the steel rocks and let out a dull cry.

The enslavement scroll then disappeared into the gold-eating worm's body.

Looking at this scene, Su Shen had a smile on his face: "Congratulations, Gangyan, now you are stronger than me." ”

Gangyan knelt down in front of Su Shen: "Gangyan will always belong to the master." ”
