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

"To conceive an offspring with a specific spiritual root, this much resource is required. If you think it's too expensive, you can choose to conceive an offspring with a top-grade spiritual root," Chu Tianxing said with a smile after hearing the other party's words.

His request was outrageous; his aim was simply to obtain more spirit stones.

Since I'm going to be a tool, I should at least earn some spirit stones. If I can't earn spirit stones, there's no point in being a tool.

Moreover, he was forced into this situation, not by his own will, so he wanted to gain more benefits.

"I don't know if what you're saying is true or false. How many resources are needed to nurture a top-grade spiritual root?" Wang Penghui asked.

The Longevity Pill, which adds five hundred years to one's lifespan, and a million low-grade spirit stones—this is no small sum of money, and he doesn't want to waste it.

Recently, the price of Longevity Pills has skyrocketed, increasing several times over.

"To nurture a child with top-grade spiritual roots, one needs a Longevity Pill that adds two hundred years to one's lifespan, five hundred thousand low-grade spirit stones, and at least a woman with high-grade spiritual roots," Chu Tianxing said with a smile.

“It’s not cheap to nurture offspring with top-grade spiritual roots,” Wang Penghui frowned.

"If you don't believe me, and if you still think it's too expensive, then let's conceive a child with a superior spiritual root. We'll cut the cultivation resources in half, and all you need is a woman with a mid-grade spiritual root," Chu Tianxing said with a smile.

"Then let's conceive a child with a top-grade spiritual root." Wang Penghui gritted his teeth. He also had a top-grade spiritual root, and he could accept paying this price to conceive a child with a top-grade spiritual root.

For no other reason than that he possesses a top-grade spiritual root. Even if he wanted to have offspring, he might not be able to conceive an offspring with a top-grade spiritual root, which means he could only conceive an offspring with a superior spiritual root.

If spending this little bit of cultivation resources can nurture a child with top-grade spiritual roots, then this effort is absolutely worthwhile.

"Alright, it's settled then. I'll absorb the Longevity Pill and the spirit stones first. I need a month to prepare. During this time, virgin female cultivators with superior spiritual roots should be ready. If it's their first time and their primordial yin hasn't been broken, there's a 90% or higher chance of giving birth to an offspring with a top-grade spiritual root. If they're not virgins, there's only a 95% chance. The more primordial yin they have, the lower the chance of giving birth to an offspring with a top-grade spiritual root." Chu Tianxing added with a smile.

"Alright, here are the spirit stones you wanted. I don't have that many longevity pills. You can take these twenty-year longevity pills first. If I find out that you dare to deceive me, I will definitely grind you to dust later." Wang Penghui didn't know why he chose to believe Chu Tianxing's nonsense.

However, having made his choice, he had nothing to hesitate about or regret.

"Just wait for my good news. A year from now, if you've prepared the cultivation resources as I requested and haven't produced a top-grade spiritual root offspring for you, you can grind me to dust," Chu Tianxing said with a very confident smile.

After taking the spirit stones, Chu Tianxing entered the room that the other party had arranged for him.

As soon as Chu Tianxing entered the room, he poured out 500,000 low-grade spirit stones.

If we're going to put on a show, then we should go all the way.

This is a crucial moment to gain the other party's trust; he doesn't want to be dissected and studied.

So, the necessary feints still need to be made.

Therefore, Chu Tianxing simply sat on the pile of spirit stones and then, every once in a while, sent these spirit stones into his Purple Mansion space.

As expected, just as Chu Tianxing had anticipated, divine senses would sweep over him every day while he was in this room.

In the first few days, his spiritual thoughts were monitored very intensively and frequently.

However, as time went by, they did not find any signs of Chu Tianxing escaping, so they stopped monitoring Chu Tianxing's every move.

"This guy shows no signs of running away?" Wang Penghui said, looking at a Foundation Establishment cultivator beside him.

"No, he has been staying in his room cultivating and hasn't gone out," the Foundation Establishment cultivator said.

"Okay, I understand." Wang Penghui frowned.

Judging from Chu Tianxing's demeanor, he doesn't seem to be lying. He must be serious. If Chu Tianxing had something to hide, he would have already run away by now, instead of staying obediently at home.

In the blink of an eye, the month that had been agreed upon with Chu Tianxing had passed.

"Senior, is this woman ready? She must have at least a high-grade spiritual root." Chu Tianxing asked Wang Penghui.

"Everything's ready. Now it's your turn to perform." Wang Penghui smiled.

For the Wang family, there are many women with superior spiritual roots, but those who possess superior spiritual roots and are still virgins are quite rare.

Furthermore, this operation was conducted in secrecy, and he did not want it to become public knowledge, making it even rarer for female relatives to possess superior spiritual roots and remain virgins.

These women must be his direct descendants, members of his clan.

If it were someone from another branch of the clan, he would be doing these things to benefit others.

The woman he brought to Chu Tianxing today was his direct descendant, his great-granddaughter, and the pride of the Wang family. She had just turned eighteen, and he was preparing to send her into a sect for proper cultivation and training.

For some large cultivation families, which have abundant resources, in order to cultivate the loyalty of their members, they will usually have their children join a cultivation sect when they come of age.

Because at this age, they are already much more sensible, have been nurtured in their families, and have a certain degree of loyalty to their families, they also have certain advantages when they enter a cultivation sect.

The woman in front of me is named Wang Yanfei. She possesses a superior spiritual root and has reached the peak of the ninth level of the Qi Refining Realm. Once she joins a cultivation sect, she will soon be highly valued by the sect.

She really couldn't understand why the old ancestor Wang Penghui had suddenly summoned her without saying anything about it, and she felt a little uneasy.

In the Wang family, the Golden Core Ancestor wields absolute power and can control their lives and deaths.

"Ancestor, why did you send me here?" Wang Yanfei asked, looking at Wang Penghui.

"Are you willing to make sacrifices for your family?" Wang Penghui asked.

"I'm willing." Although Wang Yanfei was very unhappy, since the ancestor asked her this, she had to say it in a good way, even though her words were somewhat against her will.

"Since you're willing to make sacrifices for the family, then you'll cultivate with him today." Wang Penghui was too lazy to waste words with the other party and went straight to the point.

"Ancestor, what did you say? You want me to cultivate with him?" Wang Yanfei's eyes widened. She couldn't understand it at all. She thought that the ancestor had summoned her today because there was something good waiting for her, but she didn't expect that he would ask her to cultivate with an unknown boy.
