Su Xing returned to the room and took out a low-quality "Star Source Heart".

The heart of the stars is taken from the star crystal core in the starry sky.

Every star is a small world, and its star crystal core contains many world rules.

If a martial artist below the holy realm rashly refines the heart of the starry sky, he will be overwhelmed by the powerful power of rules filled within.

When the holy realm martial arts practitioners who refine the heart of the stars can obtain the power of internal rules, which will be of great benefit to the improvement of their cultivation.

The stars and the heart are divided into four grades.

Among them: the lower-grade star source heart corresponds to the cultivation level of the Saint Realm, the middle-grade star source heart corresponds to the cultivation level of the Great Saint Realm, the upper-grade star source heart corresponds to the cultivation level of the Saint King Realm, the best-grade star source heart, and the Saint King Realm.

The difference is in units of one hundred, for example: a medium-grade star source heart is equivalent to a hundred low-grade star source hearts.

Su Xing's cultivation is at the high level of semi-saints, and it seems very luxurious to refine the lower-grade star source heart.

However, as long as he can quickly improve his cultivation level, he will not feel heartbroken at all to cultivate resources.

"Wow!"

After taking a star source, Su Xing took a hot magma, which flowed into the abdomen from his throat, and then turned into a huge volcano, exploding in his abdomen.

The endless energy was like thousands of wild horses running out of reins.

Su Xing's body was shocked and almost fell to the ground.

He hurriedly used his natal stars and began to refine the surging energy in his body.

The rapidly rotating natal stars produce a powerful traction force. When they reach the extreme, they actually turn into a "black hole".

Countless energy in Awakened his body gathered towards his natal stars.

As visible to the naked eye, his natal stars are growing stronger bit by bit.

After an hour passed, Su Xing refined the energy of the star source heart. After he felt it carefully, his cultivation became more and more profound and concise.

"It will take several months or even half a year to refine a star source heart. The best ones will take at least half a month. Even people like the true dragon saint, the young master of the divine weapon, and the son of the beast god, it will probably take one day, or several days."

"And I only need an hour."

The speed of refining the heart of the stars is related to a person's understanding and potential.

The speed of Su Xing refining the Star Source Heart is simply terrifying.

In this way, his cultivation efficiency will increase by a factor of a factor.

Of course, there is also a prerequisite for this, that is, he must have enough hearts of the star source.

"These thousand Star Source Hearts are enough for me to spend a while. At least in the three months on the Dragon Martial Saint ship, I don't need to worry about Star Source Hearts."

Thinking of this, Su Xing began to concentrate on practicing.

One hour can refine one star source heart, and twelve hours a day can refine one star source heart.

There are 120 pieces in ten days, and 360 pieces in a month.

Three months later!

After Su Xing's retreat ended, all the thousand star source hearts he bought from Tianbao Villa have been refined.

If this incident spreads, it will definitely cause a huge sensation.

It took decades for an ordinary semi-saint to refine a thousand star source hearts, and then it only took three months to wake up.

Of course, if you reach the semi-saint level, your life span is very long, and decades of time are nothing.

Usually, semi-saints and saints will take several years to retreat in a slightest time.

"Boom!"

A very powerful aura emanated from Su Xing's body.

Refining a thousand star source hearts, his cultivation level broke through to the peak of the semi-saint in one fell swoop.

"Other semi-saints spend at most dozens of star source hearts, which is enough to improve their cultivation level by one stage. People like the Divine Soldier Shaozun probably only need a few hundred star source hearts, but I have consumed a thousand star source hearts..."

Su Xing secretly smacked his tongue.

But there was no trouble.

This is a good thing, which shows that his body has great potential.

Comparing the human body to a water tank, cultivation is the water in the water tank. The larger the water tank, the more water it can hold, and the explosive power will naturally be stronger during the battle.

"I don't know how many low-grade star source hearts I need to break from the semi-saint peak to the holy realm." Su Xing could not estimate it specifically, but it must be more than a thousand.

In addition, from the semi-saint breaking through to the saint realm, the mind and nature also need to pass. If you do not have deep understanding of the power of rules, even if you have the resources to cultivate, you will not be able to break through your cultivation.

It sounds very troublesome.

In fact, if you reach the semi-saint or saint realm, it is very difficult to improve again. Many semi-saints have spent dozens or hundreds of years, or even a lifetime, and it is difficult to break through again.

"I don't know, with my current cultivation and combat power, what level has I reached?" Su Xing curled his lips. When he was at the advanced level of semi-saints, he could easily defeat ordinary saints.

Now that the cultivation level has increased to the peak of the semi-saint, the combat power has naturally increased by a factor of a factor.

"Boom boom!"

The speed of the Dragon Martial Saint Ship slowed down, and it seemed that it was about to reach its destination.

Su Xing walked out of the room and came to the deck. Looking around, a huge barrier appeared between the heaven and earth ahead, falling from the highest sky and experiencing thousands of miles deep into the ground.

"What a great formation that passes through the sky and the earth, it can be called a divine formation, which divides the heaven and earth, and forms a world inside and outside." Su Xing couldn't help but exclaim in his eyes.

Inside the formation, it belongs to the territory of "Nan Di City".

"Wow!"

A huge mysterious rune appeared on the formation light curtain, and a ray of light shot out, covering the Dragon Martial Saint Ship.

After a while, the light disappeared, and then a gap appeared on the light curtain for the Dragon Martial Saint Ship to enter.

This is a testing method, very strict.

If the Dragon Martial Saint Ship is not used, others will not be able to enter the Nandi City at all. If they break through rashly, they will be directly killed by the formation.

"Garden bun!"

"This is called the 'Nanwu God Emperor Formation'. Have you never seen it before?"

The young men of the Lu family also climbed onto the deck and couldn't help but sneer when they saw Su Xing's look of amazement.

Su Xing glanced at Lu Yuanhao and others and said, "Are you going to give me the heart of Xingchen Yuan?"

"you……"

When he mentioned Xingchen Yuanxin, Lu Yuanhao and others suddenly looked dark.

It's like a scar has been uncovered.

"You wait and see!"

Lu Yuanhao and others threw a harsh word and left the deck directly.

At this moment, in public, they were unwilling to say more to Su Xing, so as not to tell Su Xing about the bet he had made three months ago and make them lose their faces.
Chapter completed!
