This secret method is not difficult, but the premise must be mental cultivation before it can be practiced.

At the half-step God of War stage, to refine a cosmic treasure such as Sumeru Golden Mountain, the only way to refine it is to rely on magical mental strength!

"If nothing else, it will take half a day to practice!" After reading it carefully, Lin Feng immediately had a judgment, and then sat down directly in the main hall, and began to learn this secret method calmly.

"Ladies and gentlemen, let's discuss the question of where the little junior brother will go to practice next, right?"

"That's right! After all, the little junior brother can't live in the human world forever!"

"After refining the Sumeru Golden Mountain and suppressing the Heavenly Spirit Clan, he can indeed consider going to the Endless Universe to make a good living!"

"I believe that with the talent of the little junior brother, the growth is bound to be very fast!"

............

Lin Feng was quietly comprehending the secret method, and the powerful people didn't seem to be ready to be idle, and they started talking about it one after another.

For them, of course, they hope that Lin Feng can grow up safely and steadily.

But they know even more that a comfortable growth environment can't cultivate a real strong person!

The human world, once there is no threat from the Celestial Spirit Race, will be an absolutely comfortable world!

In such a world, it is not easy for Lin Feng to grow up!

Therefore, no matter what, these senior brothers and sisters of his must plan Lin Feng's next growth path!

"I suggest that the little junior brother go directly to the Supreme Civilization. ”

"No, no, no, in the supreme civilization, it's too dangerous. If you provoke a big enemy, the little junior brother is afraid that even if there is a Sumeru Golden Mountain to protect it, it will be difficult to complete it. After all, the little junior brother can only exert the negligible power of the Sumeru Golden Mountain!"

"High civilization!"

"I also agree, let the little junior brother go to the higher civilization!"

............

In the midst of the gossip of a group of powerful people, time passed unusually fast.

In the blink of an eye, it's been half a day!

"It's done!"

Suddenly, Lin Feng jumped up from the ground and at the same time a smile broke out on his face.

The secret method has been practiced!

In other words, he can refine Sumeru Golden Mountain at will!

"Little junior brother, don't hesitate, let's start directly!" the mighty ones reminded one after another.

"Hmm!"

Lin Feng nodded heavily, slowly closed his eyes, and began to urge the secret method.

Buzz, buzz.

Suddenly, ripples of time and space continued to emerge in the main hall.

And Lin Feng's body disappeared in place strangely.

"Wow. The next moment, Lin Feng appeared in this special space.

Looking around, there is complete nothingness.

Only not far ahead, there was a white mist, exuding strange and majestic fluctuations.

"According to the introduction of the secret method, this is only the heart of Sumeru Golden Mountain!" Lin Feng's gaze stared at the mist, and his heart was pounding.

He understood that as long as he refined that white mist, it would be equivalent to refining the Sumeru Golden Mountain, the supreme treasure of the universe!

"Let's go!"

Without any further hesitation, Lin Feng's eyes sank, and he was ready to start refining with all his might.

For a while, countless mental forces penetrated into the white mist.

Extremely smooth!

Mental power is a magical power, even the heart of the universe treasure cannot be resisted.

This is also the reason why Lin Feng relied on the secret method to refine the Sumeru Golden Mountain.

You must know that a cosmic treasure is never "unruly"!

Not to mention a half-step god of war like Lin Feng, even a powerhouse that surpasses the stellar level by tens of millions of times, he can't control it, let alone forcibly penetrate its Treasure Heart.

Only a mental cultivation like Lin Feng can rely on the subtle mental strength means to refine smoothly!

This is the magic of mental strength, and it is also a great opportunity for Lin Feng!

"Huh, it's so comfortable!"

Lin Feng, who had just penetrated into the heart of Sumeru's Golden Mountain, only felt extremely comfortable physically and mentally, as if the baby had been cared for by his mother.

Whether it is the soul or the body, it is extremely comfortable!

"My body is constantly improving, and my mental power is also improving?" The more he penetrated, the more comfortable Lin Feng felt, and at the same time, he was pleasantly surprised.

Because, under Xiao Qi's prompting, Lin Feng found that his physical and mental strength had been greatly improved under the nourishment of the heart of Sumeru Golden Mountain.

"As Senior Brother Nine said, refining the Sumeru Golden Mountain can help me improve my life level!"

As soon as he thought of this, Lin Feng no longer wanted to be distracted, and began to continuously infiltrate the heart of Sumeru's Golden Mountain according to the secret method......

And so, exactly five days later.

Lin Feng, it was a success!

The heart of Sumeru's Golden Mountain was completely infiltrated by him and had his brand!

"Boom!"

At the moment when he finally took control of Sumeru Golden Mountain, his inner world trembled violently.

Immediately after, the world in his body expanded wildly, and the Netherworld Blood Sea was even more terrifying!

What's even more wonderful is that the entire body is empty in the sky, and purple qi is endless.

The Netherworld Blood Sea seemed to be boiling, and countless essences flew up into the firmament and turned into stars.

"My life level has jumped again?" At this moment, Lin Feng held his breath, and it can be said that he was extremely excited.

He understands that the great expansion of the inner world is to become a symbol of the god of war in the true sense!

After a long time......

Lin Feng's inner world finally stopped expanding and tended to stabilize.

And Lin Feng also began to concentrate on the inner world, and the corners of his mouth slowly appeared with absolute ecstasy.

I saw that at this time, the world in his body was about nine thousand miles in radius!

Compared to the half-step God of War period, it has increased by nine times!

The most important thing is that in the sky above the Netherworld Blood Sea, at this time, the purple gas is swirling and the stars are dense!

Purple gas, extremely rich, stretches the entire sky!

There were thousands of stars, each one shining with golden light, surrounded by blood-colored divine patterns!

"I, I, I, I have surpassed the limit of the God of War level?" Feeling the movement of the world in his body, Lin Feng could not hide the excitement in his heart.

He knew that now, although he had not reached the planetary level in the true sense, he had already surpassed the limit of the God of War level!

The reason is very simple, an ordinary god of war level, the inner world is at best a few miles of purple qi.

As for the stars, they are all ordinary, just a few.

And what about Lin Feng?

The purple qi stretched over the entire Netherworld Blood Sea, and there were more than a thousand stars dotted with the sky!

Every star seems to contain terrifying energy, which is several times stronger than other extreme war god levels!

You must know that the sea of Lin Feng's inner world is the Netherworld Blood Sea!

The Netherworld Blood Sea Essence and the Heart Energy of Sumeru Golden Mountain, the stars that have been derived together are beyond the imagination of ordinary people!

It can be said that any star in Lin Feng's inner world is enough to easily crush other extreme war god-level stars!

The gap is simply immeasurable!
