Liu Feng is no stranger to this kind of dantian upgrade. His original dantian also came over step by step.

An hour later, the dantian had completed the upgrade. The corresponding Liu Feng's Yin Evil Technique was also cultivated to the second level of the early stage.

After the upgrade was completed, Liu Feng did not stop. Instead, continue to cultivate.

And just like that, another three days passed. Liu Feng ushered in the second upgrade again. Without any suspense, the second dantian was successfully upgraded again. The Yin Sha Technique has also been practiced to the third level of the initial stage.

With such a cultivation speed, it was like riding a rocket. Rubbing up.

In this way, Liu Feng continued to cultivate and improve.

A month has passed in a blink of an eye. At this time, Liu Feng's second dantian had already reached the ordinary ninth layer. One more step forward, and you will be able to break through to the Martial Saint realm.

Liu Feng stopped at this time. A month of penance made him very boring. As the saying goes, if you want to be fast, you can't reach it, and cultivation also pays attention to a step-by-step, combining work and rest.

I stopped and looked at the Soul Eater Fan and found that it had been a month. The Soul Eater Fan has been restored. The last two percent are left to be fully repaired.

This result made Liu Feng very satisfied. He released his consciousness again and looked around. I found that everything around me was normal, and the prohibitions I had arranged were all in good condition.

After Liu Feng finished resting, he adjusted his spirit to the best. Then the next round of cultivation began.

After entering the Martial Saint realm, his cultivation speed suddenly became sluggish. However, this slowness is also relative to the previous month.

Compared with other martial saint masters, Liu Feng's speed was still very against the sky.

In this way, after Liu Feng hadn't cultivated for a while, he would stop and rest. Then, after the mental adjustment is good, he will continue to practice next time.

Half a year has passed in a flash, and Liu Feng is still in deep retreat at this time. There was no sign of going out of the country.

Tatar was waiting outside the cave at this time, Liu Feng had said before. If it is half a year later, there is no customs clearance. He let him return to Earth alone.

Now the half-year period has arrived. He has also successfully broken through to the Reiki stage. And it has directly reached the middle stage of Reiki. is even higher than Liu Feng's level.

After waiting here for a day and a night, there was still no movement of Liu Feng about to leave the customs. The Tatar did not linger any longer, and the demonic energy of his hands surged, tearing out of thin air.

In the void, a spatial crack immediately appeared. The Tartar immediately pierced through it, and the next moment the spatial rift vanished. The surroundings were back to their original state.

And with the help of the best Yin vein, Liu Feng has reached the final stage of breaking through the aura stage.

It seems that the second dantian can be upgraded to the early stage of aura. At this time, Liu Feng suddenly had a bold idea.

Since his original dantian can be expanded and strengthened, then the second dantian should also be applicable. If you can strengthen the second dantian, then your strength can skyrocket.

However, this is naturally to take a certain risk, and it is not so simple to strengthen the dantian. Although Liu Feng had experience before, this method of breaking and standing up was not absolutely safe.

Liu Feng thought carefully for a long time, and finally decided to strengthen the dantian.

If it were a different time, Liu Feng would definitely not do it. But now is a special period, and the split soul of his enemy, the bloodthirsty Shura, has descended to the human realm.

Although his cultivation speed is not slow, it is not so easy to raise to the level of soul separation with the bloodthirsty Shura.

At the moment, the situation is getting more and more chaotic, and there is not much time left for me. Once you wait for the bloodthirsty Shura to come back to your senses, or if you meet other masters in the upper realm, your strength is not enough.

If you can successfully strengthen the second dantian, your strength will definitely increase.

With his two strengthened dantian and a demon pill, plus his own divine consciousness comparable to the early stage of condensation. The early stage of concentrating on the master also has the strength to fight.

Because at this time, the second dantian did not break through to the aura stage, so the second dantian was still only true qi. After Liu Feng decided, he immediately began to compress the true qi in the second dantian.

A moment later, all of the True Qi was compressed into a single True Qi projectile. Seeing that it was no longer possible to compress at this time, Liu Feng controlled the projectile to start rotating at an extremely high speed.

As the speed of rotation became faster and faster, the second dantian also began to tremble. At the same time, wisps of true qi escaped from the high-speed rotating true qi projectile, and then they were absorbed by the trembling second dantian.

In this way, about half an hour passed, and the True Qi Projectile had already shrunk a lot compared to before. And those true qi that escaped made the second dantian much more stable.

At this time, Liu Feng suddenly controlled the True Qi Projectile and suddenly froze.

With a bang, the True Qi projectile exploded, and at the same time, the second dantian was also shattered.

At the same time, an aura pill was swallowed by Liu Feng in an instant. The next moment, the aura transformed by the Aura Pill appeared in Liu Feng's dantian.

Just like last time, Liu Feng's newly shattered dantian immediately began to change under the stimulation of the aura.

The fragments of the dantian turned into stars, and then formed a whirlpool. The whirlpool continued to accelerate and rotate, and at the same time, the aura transformed by the Aura Pill was absorbed into it.

What needs to be explained here is Liu Feng's two dantians. Although the attributes are different, they all belong to the same kind of energy. The aura needed in the second dantian can also be replenished through the aura pill.

This is because the Reiki energy replenished by the Reiki Pill is a neutral energy. It can not only replenish the positive energy in the first dantian, but also replenish the negative energy in the second dantian.

However, the dantian has a characteristic, that is, it can automatically transform this neutral aura into the free attribute of the dantian.

This is why Liu Feng was able to replenish the energy of the second dantian through the aura pill.

In fact, if you think about it, Liu Feng's aura pill came from the Yin Ghost Master. The Yin Demon Master has been preparing for thousands of years of rebirth. It was absolutely impossible for him to stay for himself, and he could only replenish the aura pill for the positive dantian.

In the same way, those spars in Liu Feng's hands can also provide energy for the second dantian. It's just that the energy in the spar can only speed up the usual cultivation speed a little, and it can replenish energy relatively quickly.

If you want to quickly improve your level, you still need a natural place like the best Yin Vein. Since the best Yin vein can be quickly improved, the cultivation speed of the negative exercises. In the same way, there will naturally be places that can speed up the cultivation of positive exercises.

This kind of place that can speed up the cultivation of positive exercises is called the spiritual vein. It is also divided into grades. It's just that in the human world, such a spiritual vein is more difficult to find than the yin vein.

However, although it is said that the spiritual veins are difficult to find, the places where people live are dominated by positive energy. Therefore, although the spiritual veins are scarce, the cultivation of the positive exercises is still much simpler, and therefore dominates.

If you combine it with high-quality spars for cultivation, the speed will not be slow. This is also the reason why Liu Feng gave everyone two medium-grade spars before leaving.

He believed that if everyone completely absorbed it, even if they couldn't break through to the aura stage, it would definitely not be far behind.

Let's talk about Liu Feng's second dantian, after being stimulated by the aura transformed by the aura pill. It succeeded in making the dantian begin to upgrade.

When the aura produced by the Aura Pill was about to be exhausted, the whirlpool finally stopped. No longer continues to absorb aura.

At the same time, the scattered fragments began to change constantly. It didn't take long for a new dantian to be generated.

Liu Feng suddenly felt a huge amount of energy gushing out of the newly generated second dantian. I felt this feeling before, when the first dantian was upgraded to the aura stage.

At that time, a wave of energy also poured out from the dantian, quickly traveling through the meridians of the whole body. The energy at that time felt very warm, which made Liu Feng feel warm.

And this time, the energy gushing out is no longer warm, but cool. But it's not uncomfortable, it's like a spring flowing through in the summer. It's not warm, but it's refreshing. It's very comfortable.

The process lasted less than ten minutes before it dissipated.

Liu Feng found that after the baptism of energy just now.

Although the meridians in the body did not directly double the meridians like when the first dantian broke through to the aura stage. But at this time, the meridians became more tenacious, and when the negative aura was running, it was smoother and more natural.
