A group of people returned to the laboratory very excitedly, and burned the few waste spirit stones that Lu Xiaoman did not finish, these non-humans are more sensitive to aura, and after their own experience, it was confirmed that Lu Xiaoman guessed correctly, the strong acid destroyed the stable internal structure of the waste spirit stone, and it was okay if it was not heated, once heated, the spirit stone was heated and shattered, and the remaining spiritual energy inside was able to overflow.

In order to verify this conjecture, they began to do a new round of observation experiments, this time Ye Zhou laid out a small array of time, and completed twelve hours of strong acid immersion in the array, but what was put into the acid solution was not a waste spirit stone, but five top-grade spirit stones, the highest spiritual energy content in the best spirit stone, if the re-test was successful, the waste spirit stones produced by the spirit stone mines of other great worlds could be completely utilized.

This experiment was operated by Ye Zhou, Lu Xiaoman stood aside very nervously and watched, in the time acceleration array, the best spirit stones soaked in the strong acid did not see any reaction, and it took a long time to see that each top grade spirit stone had a very small bubble, and not long after this small bubble, the time in the small array was accelerated, Ye Zhou stopped the formation and took out the beaker.

Under Ye Zhou's control, the five top-grade spirit stones flew out of the beaker lightly, hovering in front of everyone's eyes, Ye Zhou precisely controlled his Dan fire, divided into five wisps of fire with different sizes, and surrounded the five top-grade spirit stones in turn.

The best spirit stone couldn't resist the temperature of the demon Venerable's Danhuo, and it shattered into powder one by one in an instant, and the rich aura scattered in it, Lu Xiaoman only felt that a huge aura wind was blowing in her face and almost suffocated her, and for the first time, she had the experience of being held breath by the aura.

Fortunately, the aura covered his mouth and nose for only a moment, and then it completely dispersed into the air, and Lu Xiaoman was also surprised by the speed at which the aura overflowed.

"The speed at which the spiritual energy of the best spirit stone overflows is also so fast! It's on par with the waste spirit stone just now! What method do you have to use to retain the aura for your own cultivation? Lu Xiaoman felt big just thinking about it.

"Soaking with strong acid is not a long-term solution, the acid will corrode the metal container, the smell of volatilization at high temperature is also very bad, the workshop is OK with a use, if you want to build a factory in the future, you need new production methods or new containers." Ye Zhou raised his hand and fanned the wind, burning the spirit stone fragments directly into slag and removing the residual acid.

"If the acid is irreplaceable, then only the superalloy meets the three requirements of acid resistance, high temperature resistance and high strength." Lu Xiaoman began to scratch his head, "I will never be able to do it alone." ”

"There are acid-resistant and corrosion-resistant superalloys smelted with the spiritual materials of the refining vessel, and the common materials used to build high-level furnaces cannot be directly used in the Wind Ring Realm, so we can only use local spiritual materials to re-study the superalloys. Smelting metal is such a thing as having to call you little brother, Bishan's apprentices and grandchildren are very good at this, plus the craftsmen in our clan study together, factory production can not be achieved in the short term, can only use the materials of low-level furnaces to deal with a few years, build a workshop and use it first, and replace the pipe furnace if it is broken. ”

"Well, the conditions are simple, there is no time to wait, Feiyang Zhenjun still needs a lot of aura to save his life."

"Put this piece down for the time being, you don't have to worry about it, you study the talisman formation and think about how to keep the aura for your own use, let's do it separately to save time."

"What about atmospheric pressure?"

"You set the temperature calibration, and let Ye Zhi do the rest."

"Oh~"

"Let's go, let's get out, it's time for you to go to the evening class."

Ye Zhou quickly emptied the table and left the empty bead with Lu Xiaoman, Feng Yuan and the two little black dragons followed behind, chatting with their divine senses, and chattering about the relationship between aura and promotion in the process of cultivating monks.

Staying in the empty bead is not able to advance to the next level, this is the consensus of the monks of all worlds, the artificial environment, can not perceive the heavenly way of the big world, there is no spiritual resonance, stay in the empty bead until death can not advance to the next realm, but stay in the outside world where the aura is thin, even if you can communicate with the heavenly way, the aura is not enough to support the needs of the promotion, it is also in vain.

If Lu Xiaoman's idea can succeed, all the monks in the Wind Singing Realm will thank her, this merit is incredible, and a proper meritorious monk will be admired in any world he goes.
