Fox Demon: Heaven rewards diligence; I will eventually achieve divine mastery of martial arts.

Feng Qi smiled gently, letting Lin Yu embrace her, her head slightly lowered, resting against his chest.

"But speaking of which, since you care about them so much, why don't you explain what happened back then, so that you don't cause trouble every time you meet?"

"I'm not going to talk about this kind of thing. There's nothing to say."

"That was my own decision, not something I made specifically for them."

Feng Qi pouted and retorted shrugged.

"I think you're just too proud to admit it."

Lin Yu reached out and poked her head. Instead of learning good things, she became arrogant. He didn't know where she got this bad habit from.

"No, we're rivals in love now, you know."

"If I take the initiative to clear up the misunderstanding, wouldn't that make me admit defeat?"

Feng Qi turned her head away. When it was just the two of them, her personality was pretty much like that of an ordinary young girl.

"We're all family, why are you making such a fuss?"

"Of course! After all, we met first, so the 'official wife' is definitely mine."

"Very well, then shouldn't Your Majesty serve me until bedtime?"

Upon hearing Lin Yu's words, Feng Qi, who had just been speaking righteously and reasonably, blushed and hurriedly fled like a frightened deer.

Although she had already half-heartedly accepted Lin Yu's idea of ​​having a harem.

But serving others is still too embarrassing.

. . . . . .

the next day.

After waking up and having a simple breakfast, Lin Yu began his cultivation.

Now that we have a general direction, the next step is to further enhance our capabilities to make the rest of the journey smoother.

As he thought, dealing with the Bitter Love Tree was not a simple matter.

You need to raise your strength to at least level ten, or even higher, otherwise, those guys from Aolai Kingdom are not to be trifled with.

They were truly a group of ancient monsters who had lived for who knows how long. After defeating one of the smaller ones, a whole bunch of old monsters appeared.

'I don't know how far I can go in my cultivation with all this stuff.'

Lin Yu looked at the dozen or so demon cores of various sizes in the room and felt a sense of anticipation.

These demon cores are extremely hard to come by; there are very few demon cores at the level of a Great Demon King in the entire circle.

Fortunately, he now controls the resources of both the Wu Dynasty and the Tu Shan forces, which he can use at his disposal.

In this respect, there is still plenty.

Like the southern lands, or the Western Regions and the northern mountains.

Lin Yu also arranged for people to acquire demon cores.

Cultivation resources are always a good thing; you can never have too many.

After all, he doesn't have any concept of a limit.

Lin Yu picked up a cup of demon cores at the level of a Great Demon King and closed his eyes.

Gray qi emanated from the area, enveloping the demon core in his hand.

The demon core was enveloped in a delicate gray substance, and an invisible aura began to circulate.

It's like a giant millstone, constantly stripping away the power from within the demon core.

Previously, cultivation required consuming large amounts of high-energy food, but now this process can be completely eliminated using internal energy.

The efficiency is even higher than before.

The demon core spun continuously within the protective energy, and with each rotation, its size shrank imperceptibly by one circle.

Instead, a pure energy, which had been refined repeatedly and was neither demonic nor magical, surged into Lin Yu's body.

[You have diligently practiced the Crystal Visualization Technique and gained some insight; your proficiency has increased by 12!]

[You have diligently practiced the Ten Perfections Martial Arts and gained some insights; your proficiency has increased by 10!]

[You have diligently practiced the Nine Revolutions Body Tempering Technique and gained some insights; your proficiency has increased by 13!]

The familiar notification tone kept ringing out.

This time, however, the increase in proficiency reached a completely new level.

Lin Yu's three most relied-upon cultivation techniques have all reached the eighth level.

Without any special enhancements, the minimum increase in proficiency during cultivation is eight points.

But now, with the help of a powerful demon king's core, the harvest has been greatly enhanced.

It even increased the effect by up to 60%.

If this were done in the past, some elixirs would be used as an aid.

It's already quite remarkable to achieve more than 20%.

Compared to before, it has almost doubled.

This efficiency is truly astonishingly exaggerated.

Feeling his dramatic improvement, Lin Yu felt more confident.

The Bitter Love Tree is troublesome, and so is Aolai Kingdom.

But these are only temporary.

If one year isn't enough, then two years will do.

If two years isn't enough, then ten years will do.

He, who is capable of continuous improvement, has no shortage of time.

Given enough time, he will eventually become stronger than others, and then everything will no longer be a problem.

Lin Yu's belief grew stronger, and he became more and more focused on his cultivation.

The numbers on the system panel also continued to increase.

九转淬体功LV.8（89162/100000）、十全武道LV.8（56123/100000）、水晶观想法LV.8（58912/100000）

The time for the next breakthrough is not far off.

. . . . . .

After a week of cultivation at Tushan.

The Nine Revolutions Body Tempering Technique, which progressed faster than the other two techniques, once again achieved a breakthrough first.

Along with the other two cultivation techniques, they are also nearing the point of breakthrough.

The only cost was that the demon core of that great demon king had been completely exhausted.

One Great Demon King's Demon Core per week.

In other words, Lin Yu's gains after sweeping through the Southern Kingdom last time were barely enough for him to use for a few months.

This level of consumption is so high that calling it a money-devouring beast wouldn't be an exaggeration.

It takes thousands upon thousands of years for a demon to cultivate to the level of a Great Demon King.

As a result, it was used up in just one week by Lin Yu.

However, all of this was worthwhile for Lin Yu.

At least that's what he thought after experiencing the changes after the Nine Revolutions Body Tempering Technique broke through.

Chapter 158 No destruction, no construction; rebirth amidst flames

"It's so hot."

"Yes, it's already late autumn, why is it still so hot?"

"That's strange, everything was fine yesterday."

On Tushan Street.

Many demons were discussing this, their foreheads covered in sweat.

The weather is very strange today; it was perfectly fine this morning.

As a result, the temperature suddenly started to rise in the afternoon.

Moreover, the rate of increase is extremely fast. In just a short while, it has already reached a level similar to summer, and there is even a trend of continued increase.

This is quite puzzling.

It should be noted that Tushan is surrounded by rivers and seas due to its geographical location, and the temperature is usually very pleasant.

Even in summer, it's never this hot.
