With the stalactite mother stone in hand, the first thing Qu Ruo did was to put it in the spirit gathering array, and the dense aura prompted the mother stone to produce more stalactites, and after a few days of observation, the mother stone could produce at least one drop of stalactites every day.

"I've calculated that for every drop of stalactites produced, the mass is reduced by about one gram!"

Feng Rong added.

Qu Ruo used all the stalactites, including the two drops he got from the auction, on the two girls.

Coupled with the elixirs that Qu Ruo kept supplying, Yin Ling's cultivation was finally improved from the early stage to the middle stage of Qi refining.

And Feng Rong is even more powerful, all the spiritual energy stored in the dantian has been compressed into liquid, and it is only one step away from building a successful foundation.

"Feng Rong, stalactite is a good foundation building material, although it is not the best, it is much better than ordinary magic weapons, why don't you use it to build a foundation!" Qu Ruo commanded.

There are generally three ways to build the foundation of the cultivation realm, one is to directly liquefy the spiritual energy in the dantian to complete the foundation without any equipment, which requires a strong true element and patience, and the other is to use the natural materials and earth treasures and magic weapons to build the foundation of the spiritual energy. The third is to use the absorption and storage of heavenly and earthly treasures and magic weapons to build a foundation, this method can mostly expand the capacity of the dantian, and each realm requires far more spiritual energy than normal monks to fill the purple mansion, so it is the most powerful.

In today's world, the aura is thin, and most people use the first method to build a foundation, and they can neither find the heavenly materials and earth treasures that swallow the aura type nor dare to build the foundation with the treasures that absorb the aura type.

"Are you saying that there are pros and cons to building a foundation for the stalactite mother stone, and you want to teach me to build a foundation for the mother stone?" Feng Rong asked gratefully.

Stalactites are indeed a good thing, not only can they eliminate the disadvantages of Feng Rong's reckless cultivation in the past, but also make her cultivation move forward steadily, which has helped her a lot.

It's just that stalactites can produce a lot of stalactites, so it's a pity to use them as foundations.

"Qu Ruo, can we study the composition of the mother stone and make another one?" Feng Rong whimsically.

"Study the composition of the mother stone, do you want to learn from Professor Lin?" Qu Ruo shook his head, "The things in the cultivation realm can't be explained by science and technology, what if you take materials from the mother stone without authorization, destroy the balance inside, and lose its effect?"

Qu Ruo disagreed.

"This ......," Feng Rong insisted, "What if I don't break the balance inside?"

Feng Rong gritted her teeth and seemed to have made up her mind, took out the mirror she carried with her to look at the mother stone, and when she took it away, the mirror surface actually made waves. A fist-sized mother stone appeared outside the mirror, and Feng Rong caught it.

Stalactites were actually copied?

Qu Ruo took the two stones and found that there was not much difference between the original stone and the replica.

"Let's observe for a few days!" Qu Ruo hesitated.

The mirror in Feng Rong's hand seemed to be omnipotent, and he had long been surprised.

"Two stalactite motherstones!"

Yin Ling walked over and stroked/touched the stone repeatedly, and found that there was not much difference between the two pieces at all.

Miraculously, two stalactites emit stalactites at the same time every day, and the size and shape are exactly the same.

"What the hell is going on?" asked Qu Ruo, puzzled.

Could it be that the mirror in Feng Rong's hand can really replicate the item and be exactly the same as the original.

"That's true, I can tell you for sure, not to mention the size of the stalactite, even the molecular structure inside is the same!"

In Feng Rong's eyes, there is no difference between the two.

She begged, "Qu Ruo, now you can give me the foundation building method!"

"Yes!" Qu Ruo told Feng Rong all the methods used to build the foundation and recover the stalactite stone.

Feng Rong subdued Zhuji Dan, and when the aura in her body was at its fullest, she beat the law on the mother stone suspended in the air.

The stalactite stone vibrated for a while, turning into a ray of light that hit its dantian in a flash.

The next moment, the mother stone turned into a small dot entrenched in the Fengrong dantian, and all the spiritual energy around it rushed up, touching the mother stone, and a drop of stalactites flowed out of the mother stone was melted, and with the operation of the big and small Zhoutian, the stalactites flowed to the whole body, and the meridians were expanded and expanded little by little.

The foundation building period has been achieved!

Feng Rong opened her eyes and felt that her body was full of spiritual energy, and her own strength was much greater than just now.

"Thank you, brother!" Feng Rong smiled and asked, "Can I use this rough stone?"

Feng Rong only used the replica stalactite, and the original stone was still intact.

After getting Qu Ruo's consent, she took a mirror and looked at the original stone and disappeared in front of several people.

At the bottom of the lake outside the city, there is still the old well, the wellhead has long been sealed by bluestone, but the danger appears a few hundred meters below the well, and there are still pavilions and pavilions surrounding a huge palace, the difference is that there are no dinosaurs guarding the entrance of the main hall.

Dozens of robots in the hall surrounded a small tower more than three meters high, and the dozens of spars around the small tower were all turned into flying ashes, and all the stored energy was sucked out.

"The princess has just used the energy of the base, fortunately, this base has been rebuilt, the central tower has enough hedrons, and the energy in charge is not enough to support the replication of items, but I am afraid that the consequences are quite serious!" A beautiful female bionic robot asked: "Xingxing, can we contact the princess, I don't know why she used the central tower?"

Another robot beauty beside her who looked very similar said: "I still don't want it, the princess has told me, don't disturb her easily!"

Two twin beauty robots are the leaders of the Shadow Squad and control the entire base, and they name themselves Star and Moon.

When the two were arguing, the space fluctuated, and a fist-sized white stone appeared in front of the two, and Xingshen came out to catch the stone with his right hand.

A ray of light shot out from the mirror in her hand, Xingxing closed her eyes and pondered, opened her eyes for a while and said, "The princess has new instructions, she wants us to start cultivating the truth!"

Feng Rong passed on not only the stalactite stone rough stone, but also a whole set of cultivation methods.

Xingxing, Yueyue did not have a quenching pill, but there was a central tower to provide endless energy, and the two of them were able to transform the meridians at will, and in just a few days, they cultivated to the peak of the qi refining period.

It took countless spars to finally copy two stalactite mother stones, and the magic decision passed by Feng Rong helped them to inlay the mother stone in the dantian, and two strong lights flashed in the central tower to shine on the stars and the moon, completely transforming them, and countless energies suitable for the human body were injected into them.

The two pseudo-foundation building biochemical robots were successfully cast, and Xingxing opened his eyes: "Now that we have completed the transformation, we can go and help the princess, I will help first, you stay at the base, continue to observe the princess's every move, and if you need reinforcements at any time!"

She gave an order to Yueyue.

A flash of light flashed through the center tower, enveloping the stars, and she vanished in place.

"Yes, I know!" Yueyue took the order.
