After all, the opening time of this [Phantom Secret Realm] has only been three months.

Counting the time consumed by one's own cultivation in the middle, it is indeed a very tight time.

If you want to cultivate to break through to the third heaven realm of the Chaos Divine Technique within three months, then Su Fang must improve the efficiency of hunting.

Hunt as many higher-level phantom beasts as possible to obtain a higher concentration of phantom crystal nuclei.

Thinking of this, the Soviet side spread out the map and began to investigate it seriously.

"Well, my current position is actually on the periphery of the [Phantom Spirit Secret Realm], no wonder that Phantom Spirit Beast is so weak." Su Fang thought in his heart.

"It seems that we have to go to the central area of the [Phantom Secret Realm] to have a look, the phantom beasts there should be a little stronger." Su Fang said.

With a goal in mind, Su Yi rushed directly to the central area of the [Phantom Secret Realm].

Soon, Su Yi broke through this forest full of phantom spirit beasts, and approached a mountain range very close to the central area of the [Phantom Secret Realm].

"Passing through this mountain range, it is the central region of the [Phantom Realm]."

Su Fang said after glancing at the map.

Then he directly entered the mountain range, and the density of phantom beasts here was obviously much more dense than that of the phantom beasts in the forest, and it was even more powerful.

No, as soon as Su Fang entered this mountain range, a phantom spirit beast with the appearance of a white spirit snake rushed out.

"Hiss ......"

This phantom spirit beast in the shape of a white spirit snake kept sticking out its tongue and looked at Su Fang carefully.

Then, after gathering momentum for a while, he suddenly rushed over.

Rumble!

The phantom spirit beast in the shape of a white spirit snake directly opened its bloody mouth and smashed it fiercely, and its strength was several times stronger than the phantom spirit beast in the shape of a white lion before.

"Hmph, that's a good time." Su Fang shouted.

After traveling for a long time, Su Fang naturally came in search of a more powerful phantom spirit beast.

Now, this phantom spirit beast in the shape of a white spirit snake is powerful, which is just in line with his hunting goal.

Thinking of this, Su Fang did not relentless at all, and rushed directly over after unfolding the remnant cloud shadow body.

"Punch me."

The Su side yelled.

With all the brute strength of his own body, Su Fang directly punched into the tongue.

Suddenly, the phantom spirit beast that looked like a white spirit snake was beaten to the head of the snake and scattered.

Deal with this kind of monster that has no weaknesses in the whole body and can only be completely defeated by complete destruction.

The Soviet side also saw that only the use of brute force was the most effective means.

Therefore, the Su side did not waste his aura to perform the martial art "Nine Tribulation Thunder Fist", but only relied on his body to smash the phantom spirit beast that looked like a white spirit snake at close range.

"Roaring ......"

The phantom spirit beast in the shape of a white spirit snake roared.

The snake's tail immediately threw it at Su Fang.

Bang!

Su Fang resisted the flick of the snake's tail, and then immediately smashed it with a chaotic fist.

"Give me death! Give me death! ”

The Soviet side shouted frantically.

The fist kept smashing the tail of the white spirit snake, and it didn't take a few punches to break the snake's tail apart.

"It's not enough, you give me death!"

Su Fang shouted.

After smashing up the most threatening snake tail and snake head, Su Fang continued to rush towards the huge body of the white spirit snake.

"Scatter me, scatter me!"

The Su side shouted while smashing.

And this phantom spirit beast in the shape of a white spirit snake, after losing its most threatening means of attack, could only be beaten silently.

After a while, the huge body was directly smashed by the Soviet side and all of them collapsed.

Then, a Phantom Crystal Nucleus, which looked to be very pure, fell to the ground.

"Huhu, I'm so tired." Su Fang couldn't help but say.

This large phantom spirit beast wants to smash it all to pieces, it is simply too physically exhausting.

Even a body refining martial artist like Su Fang, who was extremely physically powerful, felt very difficult, let alone others.

"But fortunately, this time, the phantom crystal nucleus looks a lot purer." Su Fang muttered to himself.

Then, Su Fang walked to the place where the white spirit snake dissipated and picked up the phantom crystal nucleus.

"Let's see how much aura concentration this phantom crystal nucleus can increase." Su Fang said.

Then, Su Yi sat down on the spot, activated the Chaos Divine Technique, and began to cultivate.

This time, as soon as Su Fang absorbed the aura in the phantom spirit crystal nucleus, his body clearly felt that the aura concentration this time was much stronger than before.

And by completely merging this extremely pure aura into his own dantian qi sea, Su Fang could already clearly feel the increase in the concentration of spiritual energy.

"I'm afraid the concentration of this aura has increased more than ten times." Su Fang exclaimed.

Unexpectedly, after the phantom spirit beast in the shape of the white spirit snake died, the phantom crystal nucleus left behind was actually more than ten times stronger than the phantom crystal nucleus left behind by the phantom spirit beast in the shape of a white lion after death.

The effect is simply unbelievable!

You must know that the compression and increase of this aura concentration is more and more difficult the further you go.

For example, it only takes ten days to compress from one time the concentration of Reiki to twice the concentration of Reiki, but from two times the concentration of Reiki to three times the concentration of Reiki, it will take at least more than twenty days.

The difficulty and time of this aura compression are all increased geometrically.

Therefore, the higher the concentration of aura, the higher the concentration of the phantom crystal nucleus, the higher the concentration of the aura, the nature of which is much stronger than the low concentration of the aura.

Thinking of this, the Soviet side already had confidence in his heart.

"Haha, it's better to specialize in hunting high-level phantom beasts, then efficiency is perverted." Su Fang laughed.

It has been decided that only high-level phantom beasts will be hunted, and those low-level phantom beasts will be forgotten.

After all, the concentration of the aura of the low-level phantom spirit beast is too low, and it is very troublesome to kill, so the gain outweighs the loss.

With the hunt plan in place, Su Fei continued to walk towards the depths of this mountain range.

After entering the mountain range, Su Fang found that the density of phantom spirit beasts here was simply amazing, and almost every few steps, he would encounter a phantom spirit beast blocking the way.

Rumble!

There was a loud bang.

After Su Fang smashed a phantom spirit beast, he couldn't help but stand in place and panting.

Along the way, Su Fang encountered too many phantom spirit beasts.

And he didn't shy away from it at all, and almost all of them were accepted.

Therefore, the speed of the journey was delayed, and it was only possible to reach the middle of this mountain range.

"Huhu, it doesn't seem to work, there are too many phantom spirit beasts here, you have to make a trade-off, otherwise you really can't deal with it." Su Fang couldn't help but sigh.

Along the way, although he killed a lot of phantom beasts that stood in his way and obtained a lot of phantom crystal nuclei, the efficiency was still not very satisfactory to Su Fang.

After all, the time he had stayed in the [Phantom Secret Realm] had only been about three months.

Therefore, how to maximize the efficiency of hunting has become the most important issue for the Soviet side.

"Those huge phantom spirit beasts are really too hard to fight." Su Fang couldn't help but say.
