Moreover, if the stone gate was refined into his own natal magic weapon, Qin Tianchen would also have the confidence to put it into the forbidden land of Thunder Mountain, and then continue to absorb the power of thunder.

That Thunder Mountain forbidden land, even the Mahayana Venerable didn't dare to enter it, for fear of being affected by heavenly punishment, not to mention his small refining realm.

But if there was such a natal magic weapon, Qin Tianchen felt that he had nothing to worry about.

Whenever there was a thunderbolt that struck him, he could have used this stone gate to block it.

Anyway, this stone gate seems to be born with the ability to absorb the power of endless thunder.

Based on this point of Shimen, Qin Tianchen suddenly had a guess in his heart.

He felt that since the Spirit Mountain back then, since he dared to let the ten Mahayana Venerables trigger the Thunder Tribulation together, then he must have something to rely on.

Some of the treasures that resist the thunder are obviously definitely possessed.

The Mahayana Venerable would rather sit down with the exhaustion of the longevity than survive the thunder tribulation and the soul perish.

One of the most important reasons is the horror of the Apocalypse.

Since ancient times, very few Venerable Masters have been able to survive the Thunder Tribulation and Ascension.

However, Lingshan can successfully cross the tribulation ten at once, if it is said that they do not have the anti-heaven magic weapon to resist the thunder, then it is impossible for the Ziwei Ancient Star cultivation world to believe anything.

This is also the reason why countless Mahayana Venerables later went to the periphery of the Thunder Spirit Mountain Forbidden Land to search.

After thinking about this, Qin Tianchen felt more and more that his origin of this stone gate was not small.

And it is very likely to be the secret treasure in the Spirit Mountain back then.

As for the Wei family, I'm afraid they just think that this stone gate can devour spiritual power, and it has no other effect.

Because they can't experiment with the power of thunder.

Only now, after reaching Qin Tianchen's hands, did he manifest the original mystery of this ancient artifact.

"Where is this loss, it's just a profit!"

Qin Tianchen said with some joy.

Not to mention a Mahayana Venerable's inheritance, even ten pieces, I am afraid that they are not as precious as this stone gate.

"I can refine this stone gate and hide it as soon as possible, but I can't be discovered by anyone. ”

Qin Tianchen felt that he had to hide this secret, otherwise, not to mention the Wei family, I am afraid that the entire cultivation world of Ziwei Ancient Star would be worried about this stone gate of his own.

Using the Nine Heavens Imperial Thunder Technique to absorb the pure thunder power in the stone gate, although the stone gate cannot be supplied, it can also be used to offset its devouring power.

Qin Tianchen took advantage of this opportunity and began to use his natal spirit element to refine it.

"Heaven and Earth Dragon Ding!"

In order to hide people's eyes, Qin Tianchen directly refined this stone gate into another shape.

The Heaven and Earth Dragon Ding is a natal magic weapon refining method in Qin Tianchen's inheritance, which is infinitely powerful and can suppress all things.

Now that he has an innate thing like Shimen that conquers the heavens and the earth to refine, Qin Tianchen has higher hopes for his natal magic weapon.

"Poof!"

"Poof!"

"Poof!"

"Condensation!"

Spit out three mouthfuls of natal essence blood one after another, allowing his essence blood to soak the entire Heaven and Earth Dragon Ding, and Qin Tianchen carried out the condensation.

In the end, a mini dragon tripod appeared in his dantian.

The four legs of the dragon tripod are like the four legs stretched out by the dragon, supporting them up, and there is a magical mystery that cannot be seen.

Qin Tianchen didn't bother to add any other materials, because as far as any of the materials he knew now, none of them could be worthy of an innate thing like Shimen.

Although Qin Tianchen didn't know what kind of material the original stone gate was, he was very sure that it was definitely an innate thing.

And the natal magic weapon he practiced was definitely an innate treasure, and after a period of sacrifice from him, it could definitely burst out with infinite power.

This innate treasure is not inferior to the things of the ancient venerable.

After Qin Tianchen came to Ziwei Ancient Star, he saw many natal magic weapons, and almost none of them could compare to the four spirit statues in the hands of the four hidden world patriarchs of the ancient realm.

But now that the Heaven and Earth Dragon Tripod he had refined had only condensed a prototype, Qin Tianchen was confident that its power was not inferior to that of the Four Spirit Statues combined.

Only when the four spirit statues are taken together can the number of heaven, earth and stars be mobilized to suppress one side of heaven and earth, but a prototype of heaven and earth dragon tripod can.

When his natal essence blood was completely fused with the Heaven and Earth Dragon Ding, Qin Tianchen let go of the shackles of the Nine Heavens Imperial Thunder Decision.

Now the Heaven and Earth Dragon Ding is already the prototype of his natal magic weapon in a sense, and it has a great relationship with his life, so even if he does not restrain himself, he will not absorb Qin Tianchen's spiritual power without triggering it.

This allowed Qin Tianchen to store this thing in his dantian with peace of mind.

"After having this magic weapon, the Danwang Mansion is no longer suitable for my cultivation. ”

"Lei Ling Mountain may be the right choice for me. ”

Qin Tianchen thought silently in his heart.

He now has no intention of attending the so-called royal auction convention.

The reason why he was so interested at the beginning was just that he wanted to find the materials to refine his natal magic weapon.

But now that he has found the most suitable material and has refined the prototype of the natal magic weapon, his heart is no longer here.

"You can leave a certain amount of spirit stones and pills for Duanmu Invincible, let him continue to retreat in the Danwang Mansion and improve his cultivation, and I will go to the forbidden land of Lei Ling Mountain to cultivate. ”

Qin Tianchen had already made up his mind.

He took the token given to him by King Dan and came to Wei Tianhe's alchemy room.

This is the certificate that Wei Lao gave to Qin Tianchen when he left, if Qin Tianchen wanted to alchemy, he could enter his alchemy room independently and use his alchemy furnace to conduct alchemy.

This made Qin Tianchen feel a great honor, and Wei Tianhe attached great importance to himself.

Even if he didn't have to think about it, he could guess that these were probably the first people who could enter Wei Tianhe's alchemy room independently.

Every alchemist will regard his alchemy furnace as a second life, let alone an idiot like Wei Tianhe, who regards alchemy as comparable to life.

It's a pity that Qin Tianchen couldn't focus on alchemy, which made him feel very sorry.

Below Wei Tianhe's alchemy furnace, there is the fire of the center of the earth in the dragon vein, and in the fire of the center of the earth, there is a trace of dragon vein aura, which can invisibly contain the elixir, so that the quality and efficacy of the elixir can be further improved.

So this is also the reason why Wei Tianhe attaches great importance to his alchemy room.

Qin Tianchen was going to refine the Boundary Breaking Pill first, test the feel, and then use the Ten Thousand Year Spirit Grass.
