My son-in-law from a celestial sect, all my offspring are Heavenly Emperors.

"Tell me, how much lifespan and spirit stones are needed to nurture an offspring with top-grade spiritual roots?" Qin Zhenshan asked after thinking for a moment.

"This will require at least sixty years of lifespan, and 100,000 low-grade spirit stones," Chu Tianxing said after thinking for a moment.

Chu Tianxing had never conceived a child with a top-grade spiritual root, but he knew that conceiving a child with a top-grade spiritual root would consume a great deal of lifespan.

The difference between a superior spiritual root and a top-grade spiritual root is like heaven and earth.

Top-grade spiritual roots are rare even in some cultivation sects.

Once someone possesses the aptitude of a top-grade spiritual root, they can become a core disciple of a cultivation sect.

They were able to become disciples of an elder or sect leader of a cultivation sect, a position of extraordinary status.

Their future achievements will also be extraordinary.

It can be said that a descendant with top-grade spiritual root aptitude is enough to change the landscape and destiny of a cultivation family.

There is a certain probability that offspring with superior spiritual root aptitude can break through to the Golden Core realm.

However, offspring with top-grade spiritual roots, as long as they don't die young, are absolutely capable of breaking through to the Golden Core realm, and if they have enough opportunities, they can even break through to the Nascent Soul realm.

The thought of a Nascent Soul realm expert emerging from their family filled Qin Zhenshan and Qin Zhennan with excitement.

Having the opportunity to cultivate an ancestor to the Nascent Soul realm and not having the opportunity to cultivate an ancestor to the Nascent Soul realm are two completely different concepts.

Now an opportunity is presented to them, and if they miss it, they will regret it for the rest of their lives.

One hundred thousand low-grade spirit stones is not a big problem for the Qin family.

The difficulty lies in obtaining the Longevity Pill, which is extremely rare and a treasure that is hard to come by.

"Chu Tianxing, your suggestion is not unfeasible, but the pill that can add sixty years to one's lifespan is priceless. We can get a longevity pill that adds ten years to our lifespan, but a pill that adds sixty years is really difficult for us," Qin Zhenshan said.

Elixirs that can increase lifespan are not unavailable in this Immortal Destiny City.

However, these elixirs, once aged for more than ten years, become extremely precious.

Another problem is that if you take too much of this medicine, you will develop a drug resistance, and its effectiveness will be greatly reduced.

This is why Qin Zhenshan was worried and frowning. Whether they could obtain an extra sixty years of lifespan was another matter entirely.

Most pills, when taken in large quantities, will develop a resistance, and there will be a significant difference in the effect between taking the first pill and taking the second.

By the time the third pill is taken, the effect is halved, and only higher-grade Longevity Pills can be used.

Therefore, the amount of elixirs needed to extend one's lifespan by sixty years is not as simple as one plus one; it is very likely that it would require one plus two, or even one plus three.

This is what put Qin Zhenshan in a difficult position.

"Patriarch, he's waiting for my words. Should we believe him or not?" Qin Zhennan asked.

This matter presents the Qin family with an opportunity; the question is whether they will gamble on it or not.

Gambling would come at too high a price.

But if they didn't gamble, they would be very unwilling.

"Regardless of whether what he said is true or not, this is an opportunity for our Qin family to rise. We cannot give up; we must fight for it." Qin Zhenshan gritted his teeth.

The conditions Chu Tianxing proposed were relatively easy for the Qin family to meet given their limited financial resources.

The failure of this human creation plan means that the Qin family will at most lose some cultivation resources.

But if it succeeds, it will be of immense significance to the Qin family.

"Alright, Chu Tianxing, we understand. Go home and get ready." Qin Zhenshan waved to Chu Tianxing.

"Patriarch, Father-in-law, if you wish to conceive an offspring with top-grade spiritual roots, you must prepare in advance. You must take pills that increase lifespan now and absorb the spiritual power from spirit stones," Chu Tianxing said.

"Okay, we understand. We'll contact you later to tell you the specifics," Qin Zhenshan said.

If Chu Tianxing had made this plan for nurturing geniuses sound too simple, they would never have believed it.

However, after hearing Chu Tianxing say that so many cultivation resources were needed, they found it believable.

Chu Tianxing returned home, and Qin Zhenshan and Qin Zhen gathered together to discuss things.

The plan was so tempting that they would rather believe it than not.

"Patriarch, our Qin family can afford the cultivation resources, but what about the Daoist partner with a high-grade spiritual root? Also, if this matter succeeds, all will be well, but if it fails, the losses will be too great." Qin Zhennan said with a serious expression.

Qin Zhennan was a conservative. He had calculated that if the plan failed, his whole family would suffer a severe blow.

Ten thousand spirit stones are not scary; what is scary is buying longevity pills. The value of these longevity pills definitely exceeds two hundred thousand low-grade spirit stones.

The thought of the family spending 300,000 low-grade spirit stones to raise offspring is too much of an expense.

Raising offspring has already consumed 300,000 low-grade spirit stones. How will the Qin family cover other expenses?

More importantly, the spirit stones required to raise offspring are an astronomical sum.

Cultivating a master at the Nascent Soul stage would be enough to bankrupt the Qin family.

But if the cultivation is successful, the Qin family's strength will definitely rise to a new level.

Soon, the Qin family's top leaders gathered to discuss the matter.

The eldest elder of the Qin family was somewhat conservative. They were skeptical of this human creation plan and simply did not believe that such a special physique could exist in the world.

Making a plan is one thing, but putting that plan into action is another.

Now that I'm taking leave, I'm facing another problem: they have to find a way to persuade the Grand Elder's faction.

“The offspring with top-grade spiritual roots are too illusory. Once this plan is implemented, it will definitely affect the operation of the entire family. Therefore, you must prove that Chu Tianxing really has the ability to cultivate offspring with superior spiritual roots,” the First Elder said.

"Elder, what do you mean by 'what should we do'?" Qin Zhenshan asked.

"It's very simple. He must prove to me that Chu Tianxing really has the ability in this area before I will support this plan. Otherwise, I will not put the fate of the family on the shoulders of an ordinary son-in-law," the Qin family elder said coldly.

"Proof? How do you prove it? Aren't the children in Qin Xuan'er and Xiao Cui's wombs enough proof?" Qin Zhenshan frowned.

"Qin Zhen, Nan Qin Xuan'er is your daughter, and Xiao Cui is a maid in your lineage. What does that prove?" The Qin family elder sneered.

"Qin Zhenbei, what do you want?" Qin Zhennan was seething with anger. He felt that his older brother was deliberately targeting them.
