67: Grit your teeth and enter the top grade! All the merit points are squandered!

Shocked as he was, the question of whether or not to upgrade his Spiritual Root still lay before Ye An.

This was an unavoidable issue.

After all, if he hadn't known that merit points could upgrade Spiritual Roots, Ye An wouldn't have considered it.

But now that he knew, anyone would probably be thinking about it.

"Ten thousand merit points to upgrade my Spiritual Root to High Grade, and I'll still have a few thousand left!"

"It'll be enough for daily use, and I can earn more in the future!"

"It'll just be harder to earn so much again later!"

"But if I don't upgrade, I'll save ten thousand merit points, but my Cultivation time will definitely increase!"

"This is really a dilemma!"

Ye An was conflicted.

However, he eventually found a way to convince himself.

That was prioritizing.

He was a Transmigrator, and he had Transmigrated into a relatively cruel Cultivation world.

Even Spiritual Roots could be stolen, and human lives were as cheap as grass!

So, staying alive was the most important thing.

And to stay alive, the greatest reliance was strength.

Even a Husband who lives with wifes family needed the strength to have children, which clearly illustrated the point.

Without strength, let alone living, you wouldn't even be qualified to be a Husband who lives with wifes family!

And how to improve strength? Besides directly consuming merit points, it was stronger Cultivation Techniques, stronger weapons, and more powerful Spiritual Roots!

As soon as he thought of this, Ye An stopped hesitating!

"A thousand pieces of gold scattered will return; if merit points are gone, I'll earn them back!"

"I'm only seventy years old, at the prime age for doing things; not having a good Spiritual Root would be a disservice to myself!"

Thinking this, Ye An gritted his teeth and immediately shouted.

"Upgrade Spiritual Root quality!"

Sure enough, the System's voice rang out again.

"Ding! This deduction is 10000 merit points. Your Spiritual Root is about to be upgraded to a Superior Spiritual Root!"

"Estimated time: 1 minute!"

As the System's voice sounded.

Ye An also saw that the light green Spiritual Root within his body indeed began to change again.

A large amount of gray Impurities floated out of it.

At the same time, the green color throughout the Spiritual Root gradually began to turn blue from top to bottom.

And it wasn't just the color that changed.

Ye An even noticed.

The transparency of the entire Spiritual Root had also changed.

If it had previously looked like a block of ice, now it looked somewhat like a piece of jade.

Neither the texture nor the transparency was on the same level as a Middle-Grade Spiritual Root!

And through studying the "Spiritual Root Trilogy," Ye An also understood why Cultivators could only absorb Spiritual Roots higher than their own to improve their Spiritual Root.

The most important factor here was Impurities!

As the Spiritual Root's grade increases, Impurities will also decrease!

You can absorb Spiritual Roots weaker than your own, but the problem is that it's a reverse upgrade.

Naturally, no one would be foolish enough to do that!

So, to improve one's Spiritual Root, one could only seize Spiritual Roots better than one's own; even identical ones would have no effect.

Because the core of Spiritual Root improvement is to remove Impurities within the Spiritual Root!

Spiritual Roots of the same level have the same Impurities, so they won't achieve the purification effect!

One minute passed quickly.

As the Spiritual Root completely transformed into a Superior Spiritual Root.

Ye An felt that his entire state was different.

Although that feeling couldn't compare to the feeling of Mental Energy improvement.

But he knew that there was indeed a gap between a Superior Spiritual Root and a Low-Grade Spiritual Root!

"As expected of a Superior Spiritual Root, this feeling is just different!"

"I've already spent ten thousand merit points, so it's not much to spend a little more!"

"My strength has just been upgraded, so I can upgrade another wave!"

Thinking this, Ye An stopped wasting words, first picking up the Profound-grade Cultivation Technique Swift Wind Stride nearby, and immediately began to learn it.

And the System's voice quickly rang out, as expected.

"Ding! Detecting that the host is Cultivating the Profound-grade Cultivation Technique Swift Wind Stride. 100 points can be invested to upgrade Swift Wind Stride to Perfection!"

Listening to the System's voice, Ye An didn't hesitate and immediately shouted.

"Upgrade!"

"Ding! This deduction is 100 merit points. Swift Wind Stride has been upgraded to Perfection!"

As the System's voice sounded, Ye An indeed felt a stream of information rapidly surge into his mind.

Even his legs suddenly filled with power.

That feeling was as if he had been training his legs for several years!

"Having a System is just great!"

"Next is strength!"

Ye An thought, directly activating the Secret Manual Hundred Rivers Art!

Sure enough, the System's voice rang out again.

"Ding! Detecting that the host is Cultivating the Cultivation Technique Hundred Rivers Art. A maximum of 2880 merit points can be invested to upgrade strength to Golden Core Realm stage 1!"

"Do you wish to invest?"

Listening to the System's voice, Ye An swallowed his saliva.

Indeed, as strength increased, the merit points required to invest also increased.

Upgrading from Heavenly Mansion Realm stage 1 to stage 5 only required a little over a thousand points.

Good heavens, breaking through from Heavenly Mansion Realm stage 5 to Golden Core Realm actually required nearly three thousand points!

It would probably require even more later on!

As soon as he thought of this, Ye An couldn't help but set his sights on Liu Bairan.

Among his current wives, she was the only one with the highest Spiritual Root, making it easiest to earn merit points!

However, this woman was a rebel, and he was not her match at the moment. It would probably be impossible to make her obediently earn merit points for him!

Finally, Ye An decided to start with his three wives, Ye Xinlian.

He would first earn some more merit points from them.

Strength couldn't be ignored either, so Ye An could only grit his teeth and invest these nearly three thousand merit points!

"Ding! This deduction is 2880 merit points. Your strength will soon be upgraded to Golden Core Realm stage 1!"

"Estimated time: five days. Please wait patiently!"

Listening to the System's voice, Ye An smiled with satisfaction.

Previously, upgrading from Heavenly Mansion Realm stage 1 to Heavenly Mansion Realm stage 5 took fifteen days.

This time, the Cultivation upgrade was more difficult, but the time was reduced so much.

Indeed, having a good Spiritual Root had great benefits!

"It's just a pity that my merit points are also running low!"

Looking at his remaining 1940 merit points!

Ye An sighed helplessly.

He couldn't squander these merit points anymore, after all, the child in Liu Bairan's belly still needed 1500 points to be nurtured!

He also needed to quickly learn Grade 4 Talismans and Formations, which would require another 200 points!

Adding it all up, he would only have 240 merit points left to use!

This didn't even include the Mental Energy he could Cultivate with the Hundred Rivers Art after he broke through to the Golden Core Realm.

As soon as he thought of these things, Ye An got a headache.

"During these five days, I need to quickly find a way to earn more merit points!"

"To prepare for the Mental Energy upgrade in the Golden Core Realm!"

Ye An pondered in his heart.

But things had to be taken one step at a time, just like earning merit points; that had to wait until night, didn't it?

Ye An felt a bit embarrassed during the day!

Opening the door to the secret room, he checked the time outside.

It wasn't even noon yet, so Ye An wasn't in a hurry to go out.

While he had time now, he also needed to quickly deal with Black Demon Fiend's storage ring.

After all, Liu Bairan had told him last night when she gave it to him.

All of Black Demon Fiend's belongings were inside.

There was even a large group of Black Demon Fiend's subordinates inside.

They should have been brought by Black Demon Fiend, preparing to destroy the Ye family's branch!

It was just a pity that he was killed by Liu Bairan halfway.

And all these subordinates were in the storage ring, so Liu Bairan didn't take action and left them all for Ye An to deal with.

Ye An held the storage ring, but for a moment, he was at a loss.

This was the first time he had obtained such a thing, and honestly, he didn't know how to use it at all!

"Damn it, the host in his previous life was just an ordinary old man!"

"He never used it either!"

"How do I get in there?"

Ye An scratched his head in frustration.
