The fist-sized Primordial Infant Mithril Spirit Devouring Flying Ant "buzzed" sharply instigating a pair of silver-shining, metallic wings, baring its teeth and dancing claws around this secret gold rough stone.

It looked extremely angry.

There are so many spiritual things in the world, even a fourth-order magic shield with extremely strong defense can't help but bite with a pair of sharp teeth. It can swallow everything into its stomach and digest it.

But this golden stone is so strange, exuding a very "sweet and tempting" mysterious aura, which makes it full of appetite. As long as you can eat this golden stone, it will definitely be beneficial.

It pounced, gnawing frantically, its sharp silver teeth biting into the mystical rough with a piercing "crunch" sound.

"Click".

Its sharp teeth cracked, and its mouth was full of blood, but it still refused to give up.

The Yuanying Mithril Spirit Devouring Flying Ant flew angrily over the original stone, but after a short rest, the sharp teeth in his mouth grew back again, and he continued to pounce on it and gnaw wildly, and he stumbled to the end with this secret gold rough stone!

Su Chen watched in shock as the Yuan Infant Mithril Spirit Devouring Flying Ant was stumbling with the Mystic Gold Primordial Stone, sitting in the secret room for a long time.

Although the flying ants refused to give up, it was clearly hopeless.

He pondered what to do with this fifth-order secret gold primordial stone.

Even the Yuanying-level Mithril Spirit Devouring Flying Ant couldn't bite this fifth-order secret gold primordial stone, let alone other methods.

Whether it was a violent attack by a Yuanying monk like He Haibing, or a fifth-order geocentric flame to burn it, or the technique of the refining family, it was all immovable, unable to crack, unable to melt, and had no effect.

Could it be that like the old man Wei Zhennan, he can only empty this secret gold rough stone for hundreds of years, but it is useless?!

Then these 32 million spirit stones will really be spent in vain.

The corners of Su Chen's mouth showed a hint of bitterness, it seemed that he still underestimated the difficulty of refining this fifth-order god-level secret gold primordial stone.

"No, keep thinking of a way! I finally got a fifth-order secret gold primordial stone, but I can't waste it. My god-level golden gourd is in need of a fifth-order secret gold magic weapon. A fifth-order secret gold flying sword, plus a fifth-order golden gourd, this is a perfect match!"

...

this day.

Su Chen sat in the secret room, searching his stomach and intestines to think of ideas.

Tao Yao is in the Lingshan, gossiping with all kinds of bad ideas. Whether it's useful or not, it's a mouthful of muttering.

Suddenly, a wonderful idea flashed through Su Chen's mind.

"That's right!"

"Yuan Infant Mithril Spirit Devouring Flying Ant can't work, then cultivate a more powerful flying ant!"

"How did I forget there was this way!"

Su Chen suddenly opened his eyes, slapped his thigh in surprise, and immediately got up and walked out of the secret room.

This method requires a piece of material.

When he left Su Mansion, he went directly to the largest material pavilion in Holy Spirit City, the Webster's Treasure Pavilion.

There are a lot of materials there, and there should be the materials he needs.

...

Merriam-Webster's Curiosities.

The shopkeeper of Wei Da was bragging to a group of subordinate waiters in the pavilion, and all the low-level waiters were extremely envious.

Recently, he was quite proud, and under his matchmaking, he sold the fifth-order secret gold rough stone in the hands of Old Man Wei that had been stored for hundreds of years, and he made great contributions.

Just taking the commission, he took a million spirit stones in one go.

This is almost equivalent to the spirit stones that an ordinary Jindan monk has earned for ten years. You must know that an ordinary Jindan-level magic weapon is only tens of thousands of spirit stones.

The income of the Wei Da shopkeeper in charge of the Wei's Treasure Pavilion is quite large, but it is also very rare to get a commission of millions of spirit stones at a time.

When the shopkeeper Wei saw a familiar figure coming in, he couldn't help but be stunned, and hurriedly greeted him in surprise, "Old Ancestor Su, you are here! I don't know what Old Ancestor needs to buy?"

Su Chen is his big customer, for fear of the slightest neglect.

Su Chen said lightly: "Help me find a piece of secret gold material." ”

"Secret Gold?... Didn't you already buy a piece of fifth-order secret gold ore, why did you buy it?"

The shopkeeper Wei was stunned.

"No, I want a fourth-order secret gold material. ”

Su Chen said.

When the shopkeeper Wei heard this, he immediately showed embarrassment, "This... It's hard, I'm afraid. To tell you the truth, fifth-order secret gold materials are actually easier to find. However, the fourth-order secret gold is more difficult to find than the fifth-order secret gold material.

You think, there are many ancestors in the Holy Spirit State Mansion. Fourth-order secret gold materials are extremely rare, and they are exactly the gold materials that the ancestors can use, and there is a way to refine them and integrate them into the magic weapon.

There are many monks and few porridges, and the fourth-order secret gold materials are in short supply. In any Material Pavilion in the Holy Spirit State Mansion, if there is a secret gold material below the fourth order, it will hardly take half a day to be bought.

Even many refining workshops have booked this material in advance. This also directly led to the fact that there was no fourth-order secret gold material on the market at all. ”

"Oh!"

When Su Chen heard this, he couldn't help frowning.

What the shopkeeper said is also reasonable.

In the House of the Holy Spirit, there is no word of its own channel. It's really not easy to buy a piece of secret gold material.

Ordinary monks, you can't buy it at all.

But isn't there a treasurer Wei, if even the treasurer Wei can't find the secret gold material, then he won't believe it.

Su Chen came to find this Wei Da shopkeeper, just knowing that he must know where this thing is.

Su Chen looked at the loyal face of the shopkeeper Wei, patted him on the shoulder, and laughed in a low voice: "The shopkeeper Wei can be in charge of a material pavilion, and the news channels must be well-informed. You help me figure it out, it doesn't have to be too big, just a little bit. I'll buy it for double the price!"

Wei Da's shopkeeper's eyes flashed.

Double the price, then he earns double the difference.

He nodded again and again, "Su Lao Zu don't worry, I don't dare to say more, but a small amount can still be found." ”

He immediately sent more than a dozen of his attendants to the major refining workshops in the city. Some refining workshops have stockpiled goods, but they have not refined them.

Just an hour later, one of the attendants returned with a small bag of Fourth-Order Secret Golden Sands.

I weighed it and it was about ten grams.

It doesn't add up to the size of a fingernail.

If it's used for refining weapons...... With such a little bit, there is no way to refine it into a large magic weapon, and it is not enough to even inlay a blade.

At most, it is used to refine an inch-long secret gold needle.

But even if it was such a small amount of fourth-order secret gold, if it weren't for the fact that the treasurer of Great Wei had extensive contacts and was quite influential in the material industry of Holy Spirit City, others would not have bought it at all.

"Old Ancestor Su, this is a fourth-order secret golden sand grain that has been purified, the price is extremely expensive, the market price is one gram and one thousand spirit stones, and ten grams here is worth ten thousand spirit stones. ”

Wei Da shopkeeper hurriedly said.

"Thanks. ”

Su Chen said with a smile, without bargaining with him, he directly gave 20,000 spirit stones and bought the ten grams of purified fourth-order secret gold.

...

Su Chen left Webster's Treasure Pavilion and returned to the Su Mansion in the city with the secret gold that was only the weight of a fingernail.

Retreat Chamber.

He collected these secret golden grains into the spiritual mountain and fed them to the soul devouring mother ants.

The soul devouring female ant is also already in the realm of Yuan Ying, the insect body is almost a zhang long, the small head is huge, bloated and fat, and it lies in place without moving.

It opened its mouth, bit a fourth-order secret golden gold grain, swallowed it directly into its abdomen, and slowly ate all the ten grams of secret gold.

Then it lay down and continued to sleep.

Su Chen waited patiently.

After more than ten days, the primordial infant devouring mother ant laid a dark golden ant egg the size of a soybean.

This secret gold ant egg is an ant egg of the second-order foundation building realm as soon as it is born.

"Sure enough, it can lay secret gold ant eggs!"

Su Chen pinched the egg that was only the size of a soybean and couldn't help but chuckle.

The mouth of the Yuan Infant Mithril Devouring Spirit Flying Ant was too soft, and it couldn't gnaw on the fifth-order secret gold raw ore.

However, cultivating a new Secret Gold Devouring Flying Ant, the Yuan Infant Level Secret Gold Flying Ant is much stronger than the Mythril Flying Ant, and there is a great hope that it will be able to bite.

Su Chen used the magic gourd to put the secret gold ant eggs in it and raise them. It only took a short month, and after using a drop of Moon Immortal Rain, it broke through and leapt to the Yuanying-level Secret Gold Spirit Devouring Flying Ant.

It's done!

Su Chen continued to raise this Yuan Infant Secret Gold Spirit Devouring Flying Ant in the Demon Summoning Gourd, and threw the fifth-order secret gold rough stone into it, and instructed it to bite the secret gold original ore.

The whole body of the secret gold flying ant is shining with golden light, and a pair of wings are like being poured from secret gold, and even the pupils glow with a golden luster.

It is full of sharp teeth, and it is shining with the light of secret gold, which is extremely fierce.

It immediately rushed towards the fifth-order secret gold rough stone, lying on top of this one-zhang sized secret gold rough stone, as if it had a grudge, and gnawed wildly.

"Crunch!"

"Quack!"

This Yuan Infant Secret Gold Spirit Devouring Flying Ant was really strong, and it took an hour of effort to bite down on a soybean-sized fifth-order secret gold raw ore.

This originally indestructible fifth-order secret gold raw ore was finally bitten out of an extremely small hole.

Su Chen was almost dumbfounded.

It took Wei Zhennan a hundred years, He Haibing, Sun Changzhi, they each performed thaumaturgy, and the fifth-order raw ore that they couldn't help with all their efforts was broken by the Yuanying Secret Gold Spirit Devouring Flying Ants.

Of course, it's not enough to just bite it. It is also necessary to purify this fifth-order secret gold raw ore.

It swallows the fifth-order secret gold ore into its abdomen and absorbs the aura inside the raw ore.

It eats non-stop.

While eating, he pulled out small dark black fecal particles.

Su Chen had already experienced, so he took these small dung particles in his hand and rubbed them off, rubbing off the layer of powder wrapped on the outside, revealing a secret gold sand as fine as dust inside—this was a purified fifth-order secret gold, and the purity was extremely high.

"Good stuff!"

Su Chen was delighted, and fed these fifth-order secret gold to the mother ant to eat, so that it could lay more than ten new secret gold ant eggs.

These newly laid Mystic Ant Eggs seem to be more powerful than the ants laid by the fourth-order Mystium feeding.

Although, they can only be promoted to the Yuanying realm, and they can't go one step further. However, their biting efficiency was much higher than that of the fourth-order secret gold flying ants.

Su Chen put these secret gold spirit devouring flying ants in the demon gourd and raised them slowly.

It took a whole year in the outside world, and more than 300 years have passed in the spiritual mountain.

The ten Secret Gold Devouring Spirit Flying Ants that Su Chen had carefully cultivated in the Yuan Infant Realm had almost completely bitten off this piece of fifth-order secret gold raw ore the size of one zhang.

After the raw ore was swallowed by them, it was like a mythril mine, pulling out some slag, which was wrapped in purified mythical gold particles. "Produced" a bunch of purified fifth-order secret gold dust.
