However, Lin Ze didn't know the specific source of the Red Flame Copper Essence, but Qu Jingwen in the Plane Seed World knew very well the source of the Red Flame Copper Essence.

According to Qu Jingwen, the red flame copper essence is made of red flame copper and mixed with various rare metal spiritual materials, which has been roasted and refined by the earth fire for hundreds of years or even thousands of years, because it has been roasted by the earth fire for at least hundreds of years, therefore, its effect is that the fire resistance is extremely strong, and it can be roasted by countless ground fires, and after the formation, the longer the time of exercise in the earth fire flame, the closer the combination of various metal spiritual materials inside, the higher the quality, and the more powerful the effect will be.

Red Flame Copper is a kind of fire attribute essence in copper ore, and it has some relationship with the spiritual material copper essence used in the soul suppression mirror that Lin Ze obtained before, and it is only occasionally found in the associated copper ore near the volcanic fire, and its value is roughly equivalent to that of the hundred refining copper essence.

The advantage of red flame copper is that it is extremely refractory, but the body material is extremely soft, which can be said to be not suitable for refining anything, and it does not have the effect of refining copper essence that is extremely suitable for communicating aura, so it was once regarded as a waste-like thing.

Later, I don't know which genius senior refiner actually found several special metal materials that can fit with the Red Flame Copper, fused into them, and then smelted at a high temperature above the ground fire to form a special material such as the Red Flame Copper Essence.

Red Flame Copper has the length of Red Flame Copper without its shortcomings, taking into account the strong refractory surname and strength, so it has become a very suitable special material for refining Danding or puppets.

And the palace puppets here can be called tyrannical and use red flame copper essence to refine, presumably because the temperature of the earth fire here when the furnace was opened must be frighteningly high, otherwise it is not enough to make the puppet work normally here.

In fact, it's right to think about it, the Venerable Xuanyin is at least a strong person in the Jindan stage, and when a strong person like him is refining the elixir, where will the earth fire used by ordinary alchemists be the earth fire used by ordinary alchemists, and the earth fire he uses, in terms of temperature and quality, is definitely far stronger than the earth fire used by ordinary alchemists.

In the face of such a powerful earth fire, where can an ordinary puppet withstand it.

If you really want to talk about it, don't say it's an ordinary puppet, I believe that even if Lin Ze goes in, he will feel unbearable.

Moreover, what the Venerable Master Xuanyin did not expect was that his seemingly extravagant behavior was crooked.

Because, I don't know when it began, the entire cave was full of fire aura, making the space here feel like a fire like a volcano, at this time, only these puppets made of red flame copper essence can keep it from being eroded by the scorching flames here for a long time.

It's like the protective puppets made of wood outside, have they all been eroded clean?!

Regarding the topic of the Red Flame Copper Essence, it was only mentioned slightly, and it was quickly let go by everyone, because Lin Ze and they saw something more valuable in these palace ladies and puppets.

The art of making puppets, the powerful predecessors, and the powerful underground refiners are very different, especially in the choice of materials, the powerful predecessors, of course, the materials they choose will be better and more advanced.

Not to mention the rest, just the one that drove it, the things chosen by the Master Xuanyin directly made Lin Ze and his party widen their eyes.

If you want to drive the puppet, whether it is to do miscellaneous labor or make it fight, it is indispensable to supply spiritual energy, of which the nine layers and nine are mainly supplied with yuan stones.

No, the overall spiritual material of these palace puppets seen before is made of heavy metals such as red flame copper essence, and it can last for more than five hundred years without the aura being exhausted, so the power source of the driving choice inside is at least a top-grade yuan stone, so it is possible to do it here, and even, in Lin Ze's mind, it may be the power source of the spirit stone level.

This is a spirit stone! Compared to the top-level Yuan Stone, it is much stronger, and the lowest-level spirit stone can be worth ten top-level Yuan Stones.

Therefore, even if the spirit stone inside may have consumed a lot of spiritual energy by now, and only a small amount of spiritual power remains, it is enough to make Lin Ze and the other innate powerhouses covet it. (Hehe, Lin Ze is not the strength of the congenital stage, but his combat power has long exceeded the congenital stage...) ）

You must know that even a guy like Lin Ze, who is considered a local tyrant in some sects, rarely sees a trace of a top-level Yuan Stone, let alone a spirit stone, which can be said to be an exclusive item for these old monsters in the foundation building period.

"Huh?"

Zhou Qiang suddenly seemed to remember something at this time, turned back to Han Dong and shouted, "Are there also Yuan Stones in those battle puppets outside?

Everyone was also stunned when they heard this, and after Zhou Qiang's words, they reacted.

Also, I actually forgot that among the three or four battle puppets that can still move, there must be intact Yuan Stones, and even among those puppets that have fallen apart, I am afraid that there are also Yuan Stones that have not been exhausted, or even spirit stones.

Facing the burning gaze of everyone, Han Dong smiled bitterly, and then said helplessly: "It's a top-grade Yuan Stone!"

Top-grade Yuanshi!

As soon as he heard Han Dong's answer, Zhou Qiang's eyes suddenly emitted a light, and when he looked at Han Dong, it was like looking at a piece of extremely delicious barbecue.

"However......" Zhou Qiang looked a little creepy, and Han Dong hurriedly declared: "It's just that those remnants of the top-grade Yuan Stone have already consumed the aura inside. ”

"What......" Zhou Qiang looked incredulous.

Also, if it's someone else, I don't believe it much at this time.

After all, this is a top-grade Yuan Stone, and everyone wants to swallow it alone, and now Han Dong will say such a thing, no one is surprised.

Seeing the disbelieving eyes of everyone except Lin Ze, Han Dong directly spread his hands and explained calmly: "Don't forget, how could those guard puppets be so badly damaged?!

"Well, that's right!" said Li Xueni, the fairy of the hundred flowers.

As long as you calm down and think about it, you will find the problem here.

Just like Han Dong said above, if the Yuan Shi in those puppets still has enough aura, then when they come in, they will be attacked by these puppets with all their might, and at that time, how many of them will survive?!

"That's enough, Yuan Shi or something, don't you have to solve those palace puppets inside. ”

Seeing that Zhou Qiang seemed to be very unwilling and was about to continue to ask, he was directly interrupted by Lin Ze's words.

Seeing that it was Lin Ze who spoke up, Zhou Qiang, who had seen Lin Ze's strong strength, didn't dare to say anything more.

"These puppets are so strong in combat, how can we solve them? Could it be that you are still alone Li Daoyou?"

Although he didn't want to offend Lin Ze very much, Zhou Qiang was in a state of endless loss at this time, and immediately his mouth itched, and he pushed back with a straight sentence.

Glancing at him deeply, Lin Ze immediately said confidently: "Exactly, I will be able to solve them, now I will ask all the fellow Daoists to sweep the battle for Li's people on the side!"

"What?"

"Brother Li, what did you say?"

"Please fellow Daoists sweep the formation for Li, and I can clean them up alone!" Lin Ze replied again.

"What?"

After hearing the same answer again, everyone (except Han Dong) looked at the confident Lin Ze with a look of surprise.

Anyone with a discerning eye can see that although these puppets are used as auxiliaries, they are not easy to deal with, not to mention their own flexibility and vigor for the time being, just the body made of red flame copper essence is extremely hard, and it is not an ordinary Xuan soldier can be injured.

These are not the main ones, the problem is that after these times of getting along, they all know very clearly that Lin Ze is actually a fire-attribute true qi and a martial artist, and the red flame copper essence on these palace puppets is precisely his nemesis.

Now that he is saying this, could it be that he is confused about Zhou Qiang's cheap mouth?

Seeing that everyone's eyes were not only looking at Lin Ze, but also occasionally turning to Zhou Qiang's side, there was more or less blame in it, or his ungrateful taste was in it, Zhou Qiang's eyes couldn't help but roll his eyes.

Then, Zhou Qiang said to Lin Ze angrily: "Li Daoyou is better not to be strong, these palace puppets are not so simple, for the sake of insurance, everyone will act together."

How awkward it sounds, I really can't tell whether he is fanning the flames or sincerely admonishing, but everyone has long since lost hope for his mouth, so after many people heard it, they just didn't hear it.

Lin Ze did the same, he directly took his words as a deaf ear, ignored it and turned to Han Dong and said, "Han Dong, you directly set up a trap in this Dan room to temporarily trap the actions of those palace ladies and puppets." ”

Han Dong was now Lin Ze's subordinate, so he didn't hesitate at all when he commanded.

"Yes, I'll start setting it up now, give me five minutes!" Han Dong quickly replied.

After hesitating for a moment, Han Dong immediately said worriedly: "The trap array I arranged can trap those palace ladies and puppets, but it won't last too long. The strength of these palace puppets is extremely strong, and it is estimated that it will not take more than half a minute at most. ”

Lin Ze nodded when he heard this, with a satisfied look on his face.
