"Brother Lu, these are Heavenly Marrow Stones and Meteor Essence, which can be used to refine divine artifacts."

I just entered the room.

Su Peng then took out two items and placed them in front of Lu Tao.

One of them is a jade-like stone, pure white all over, about the size of a fist, called Tian Sui Stone. Legend has it that it usually comes from deep underground, and after absorbing the essence of heaven and earth for many years, it constantly transforms and becomes extremely hard.

Even a martial god would find it difficult to break the Heavenly Marrow Stone with ordinary attacks.

Besides its hardness, it also has another characteristic: through the Tian Sui Stone, one can see extremely distant places.

The other item is a meteorite essence, which fell from the sky and was formed from the essence of a star after it collapsed.

"Brother Su trusts me that much?"

Lu Tao took the two items and looked at Su Peng with some surprise.

Based on Su Peng's previous exchange of a Heaven-rank cultivation technique for a Soul Refining Fish and the telepathic communication just now, it can be seen that he is actually very cautious.

And now.

Either of the two items that Su Peng took out could be considered priceless.

If Su Peng were willing, he could exchange these two items for a lot of cultivation resources, enough for him to cultivate to the Martial King level.

and.

Both the Heavenly Rank cultivation techniques and the materials for forging divine artifacts are extremely precious, and Su Peng happens to possess all of these.

It's hard not to speculate whether he once received the inheritance of a martial god.

Faced with such a legacy, let alone someone like Lu Tao who has achieved perfect innate cultivation, even a Martial King or Martial God would be tempted.

Isn't Su Peng afraid that he might have ulterior motives?

“Brother Lu, to be honest, I don’t usually trust anyone completely, but I, Su Peng, choose to trust you.”

Su Peng smiled and said, "Whether it was fighting for the big battle before, or helping everyone cross the sea after entering the secret realm, exchanging the Soul Refining Fish with everyone, and stopping Shan Yu and others, Brother Lu's character is still worthy of my trust."

"Not at all, thank you very much."

Lu Tao laughed and said, "Brother Su, these two materials are very precious. I don't know their exact value. How many Soul Refining Fish do you need? Name your price."

"The Soul Refining Fish I exchanged before are enough for me to cultivate to the Martial King realm."

Su Peng shook his head and smiled, "Besides, Brother Lu crafted this cave dwelling to save everyone. If we can survive, a few external items are nothing to worry about."

"Moreover, it is my good fortune to be able to make a friend like Brother Lu with these two items."

Su Peng added.

It's clear that Su Peng has great respect and admiration for Lu Tao.

Upon hearing this, Lu Tao couldn't help but smile and said, "Brother Su, I've decided to be your friend. If you ever need anything, feel free to contact me anytime."

"good."

Both of them laughed heartily, and if they had time, they would have loved to drink until they were completely drunk.

After exchanging communication marks, Su Peng began cultivating inside the safe house.

Lu Tao then turned and walked into the weapon-refining room.

...

Cave dwelling.

It's actually a kind of alternative little world.

It requires numerous materials, and involves smelting, forging, and engraving arrays, making the process extremely complex.

Let alone just a few hours, even if it took several months or even several years, no one would dare to guarantee that they could successfully refine it.

That is, Lu Tao.

He can upgrade items, which gives him the confidence to refine them.

Otherwise, with his mere cultivation at the peak of the Innate Realm, it would be nothing short of a pipe dream for him to attempt to refine a cave dwelling.

Upon entering the weapon-refining room, Lu Tao controlled the safe house, causing the array to envelop the weapon-refining room.

then.

Lu Tao used the power of fire to ignite a piece of cloth, then reached one hand into the flames and controlled it with his internal energy.

Instantly, Lu Tao had control of the fire.

Upon seeing the text description on the fireball, Lu Tao smiled with satisfaction.

Lu Tao took out various materials and let the fireball burn them, frantically gaining experience.

In just a short while, the experience will be enough.

"upgrade."

Lu Tao muttered to himself.

Fireball: 16/1000 (Tier 5, superior quality, possesses intelligence, and can freely control its burning power).

Under the full force of the burning, even the body of a demon beast at the peak of the Grandmaster realm could not withstand it, and the protective aura of the Grandmaster realm was also burned away instantly.

Smelting materials is very convenient, and it can smelt up to Tier 1 materials, but it takes an extremely long time.

"It's alright, as long as we can smelt first-tier materials, that's fine."

Looking at the description of the fireball, Lu Tao breathed a sigh of relief.

He was afraid that the first-tier materials were too hard to be melted.

After all, they were only at the Innate Realm and did not have any special strange fire, so it was really too difficult for them to smelt first-tier materials.

Fortunately, the fireballs he created could be melted.

It just takes a long time.

but.

If one fireball isn't fast enough, then ten, a hundred...

Next.

Lu Tao frantically created fireballs and maxed out their experience, upgrading them to Tier 5 Superior grade.

It only took a short while.

Hundreds of fireballs floated densely within the formation, surrounding Lu Tao and radiating boundless flames.

"Melt all these materials down."

Lu Tao took out the materials he had prepared beforehand, a huge pile of tens of thousands of refining materials.

These are the materials needed to craft a cave dwelling. There are a lot of them, and it would be very difficult for an ordinary person to craft one.

"Yes, Master."

More than a hundred fireballs began to work.

The best kind of worker is one who doesn't need a salary, doesn't need rest, and is completely under their own control.

Lu Tao smiled knowingly at his own becoming a despicable capitalist.

Those who slay dragons often become dragons themselves.

Lu Tao wasn't idle either.

Each time these fireballs melt a piece of material, he needs to promptly fuse the material solution with other solutions, then forge and inscribe the array...

This process.

It's very complicated. Even with Lu Tao's divine sense, which far surpasses the perfection of the Innate Realm, it's still quite difficult for him to do.

but.

To ensure better results, Lu Tao's manufacturing process was quite rough and not very refined.

This statement—

It sounds contradictory, almost ironic, as if Lu Tao is treating this matter somewhat lightly.

In fact.

Lu Tao knew that the rougher the manufacturing process, the better the boost the upgrade would bring.

For example, when building a sect, the formations that received an amplification upon upgrading, as well as when building safe houses and giant ships, saw their formation amplification directly increase from the third tier to the second tier after upgrading.

This increase is phenomenal, and the effect is excellent.

therefore.

When building the cave dwelling, Lu Tao had to make it a bit rougher in order to achieve a better effect.

Others strive for perfection in their creations, but Lu Tao is the opposite; he's more satisfied with rougher items.

Time slips away in this endless busyness.

The fireball is powerful enough to melt some ordinary materials very quickly.

For example, fifth-tier and fourth-tier materials can be completely melted down in the blink of an eye.

However, smelting first- and second-tier materials takes a considerable amount of time.

In order to meet the deadline.

Lu Tao then created hundreds more fireballs and used them to smelt high-level materials.

The fireball was too hot; even with Lu Tao's cultivation level, he dared not collide with a fireball at its full power.

Fortunately, fireballs can freely control their temperature, and like ice hockey balls, they can also control the specific direction of combustion and the scorching point when they burn.

It won't allow the temperature to spread too much.

Very convenient.

Therefore, Lu Tao doesn't need to worry about them burning down the safe house.

In the blink of an eye, two and a half hours had passed.

All the other materials in the cave were completely melted down and inscribed with formations. Then, through Lu Tao's forging, they were fused together to create a celestial sanctuary that seemed to be encased in a sphere.

Now, only two Tier 1 materials remain to be smelted.

But it will be soon.

A short while later, the two first-tier materials that could be used to forge divine artifacts were completely melted down. Lu Tao quickly inscribed various first-tier, second-tier, and third-tier formations, and then integrated the two materials into the surface of the cave.

Let them serve as a protective shell for the cave.

After the complete fusion, Lu Tao used the ice beads to control the freezing power and cool down the cave.

In the blink of an eye, the cave dwelling was completely crafted.

The inscriptions on the cave entrance were also displayed.

【Cave Dwelling: 0/10,000 (Ninth-tier cave dwelling, as long as there are enough elemental stones to replenish energy, the interior can accommodate living beings.

The cave dwelling's capabilities are currently weak, but they can be improved and enhanced after the cave dwelling is upgraded.

The cave dwelling possesses the following abilities:

First, the Enlightenment Room, Alchemy Room, and Weapon Forging Room can provide a 100% boost to low-level cultivation techniques, pill formulas, and weapon forging.

Second, the cultivation room, where cultivators who refine their skin will have their cultivation speed doubled.

...

VI. The cave's time is the same as the outside world, and the internal lighting can be controlled by an array.

...

9. The cave has the ability to expand or shrink; it can shrink to the size of a speck of dust or expand to the size of a mountain.

...

15. The cave dwelling has the ability to hide and can blend into its surroundings, whether it be mountains or rivers. Even if you pass by the cave dwelling, you will not find it at all, and it cannot blend into the void for the time being.

...

20. The formations and surface of the cave can withstand a full-force attack from a mid-stage Martial God without any damage, but this only applies to martial arts attacks, not divine artifacts.
