I practiced carefully three times.

And after each success.

Chen Feng finally started to formally refine the ice-based spiritual liquid.

Although this sixth-grade spiritual liquid only requires four kinds of heavenly and earth treasures, the refining process is not simpler than that of other sixth-grade spiritual liquids.

The ice-blade dark spirit herbs, cold fog flowers and purple water cold stones all have extremely fierce ice-cold attributes.

During the refining process, if you are not careful, it will cause the spiritual liquid to explode.

Although Wanhai Glazed Dew has no conflict with the ice-attributed heavenly treasures, it is easily affected by the ice-attributed heavenly treasures.

The most important thing is that the Wanhai Glazed Dew is very easy to freeze. Once the Wanhai Glazed Dew that is integrated into it freezes during the refining process, it will definitely lead to the refining failure.

After Chen Feng adjusted his emotions, he first let the white flames of swallowing the sky condense into the Heavenly Gunpowder Cauldron in the space of his heart.

The heart pattern that was successfully carved in the space of the heart just now, and after feeling the Heavenly Gunpowder Cauldron condensed in the space of the heart, a force of traction was released on it, covering the Heavenly Gunpowder Cauldron.

After Chen Feng felt the heart pattern react, a reassuring smile appeared on his mouth. After all, he could not simulate the effect of the heart pattern during the previous drill.

Next, he followed the drill steps and included the treasures of heaven and earth such as the Ice Mirror Dark Spirit Grass and the Cold Mist Flowers into his Heavenly Gun Powder Cauldron in turn.

He controlled the Sky Gunpowder Cauldron very slowly. After all, there must be a difference between real refining and drilling.

During the process of refining spiritual liquid, if you are not careful, it will lead to a complete failure of refining.

He tried his best to achieve extremely perfection in every step. After using a variety of heart-refining methods, he let the Ice Mirror Dark Spirit Grass, Cold Fog Flowers and Purple Water Cold Stones be in a stable state.

As for the Wanhai Glazed Dew, he condensed more heat to ensure that it would not suddenly form ice during the process of refining the ice-based spiritual enlightenment liquid.

Everything was under Shen Feng's control and was proceeding in an orderly manner.

A strange and fiery force is released from the heart pattern in the space of the heart.

Chen Feng could feel that his heart was getting hotter and hotter, and that strange hot force could penetrate into the Tian Gunpowder Cauldron without any hindrance.

Now the entire Tiangut Powder Cauldron is in a mysterious state.

The heavenly and earth treasures such as the Ice Mirror Dark Spirit Grass have long turned into liquids, and then gradually merged together under Shen Feng's control.

Chen Feng must control the effect of each treasure. If any treasure of heaven and earth is too strong, then he must weaken the effect of it.

This is the only way to ensure that the ice-based enlightenment liquid is finally successfully refined.

Of course, these treasures of heaven and earth are placed in sufficient quantities in the Tiangut Powder Cauldron, so the treasures of heaven and earth will not have too weak effects.

For example, to refining ice-based spiritual liquid, only half of the effect is needed in an ice-mang dark spirit herb. Chen Feng cannot break the ice-mang dark spirit herb and then put it in the Tiangut Powder Cauldron.

This way, breaking the treasures of heaven and earth will greatly reduce the effect, and it may not necessarily directly cause the effects of the treasures of heaven and earth to be lost by more than half.

Therefore, Chen Feng can only weaken those treasures with too strong effects during the refining process.

As time passes by minute by minute.

When the most critical step is to refine ice-based spiritual enlightenment liquid.

The heart pattern in the heart space began to flash quickly. Every time it flashed, the flame on the Tian Gunpowder Cauldron became stronger.

After it flashed more than a dozen times.

The burning star lingers around Chen Feng's heart, and its effect is constantly penetrated into the space of the heart.

Similarly, the colorful Xuanxin Flame and the blood-cleaning purple flame quickly surrounded Chen Feng's heart.

After these three kinds of heavenly fires surround the heart in this way, the amount of spiritual liquid can be formed can be increased.

At some point.

When a medicinal fragrance spreads in the room, four cyclones faintly condensed around Shen Feng.

When the fragrance and movements in the room were getting more and more intense, under Shen Feng's control, the Tianhuo such as Ranxing and Qicai Xuanxinyan joined forces to suppress these movements that were about to break out.

Finally, the smell of medicine and other movements remained in the room.

As for the spiral of heaven, the sunken wind cannot be suppressed, so four cyclones once again appeared above the forbidden demon land.

At first, six different colors of light flashed by. After many people noticed the movement, they looked up at the sky. They thought that the mysterious heart refiner had definitely refined another four-rotation sixth-grade spiritual liquid.

But some powerful people from the ninth level of the Divine Yuan Realm in the Forbidden Demon Land frowned tightly. Just after the six different rays of light of different colors flashed, it seemed that the seventh color flashed faintly.

But the seventh color was too light and almost impossible to see with the naked eye, and it flashed very quickly.

Therefore, only the ninth level of the Divine Yuan Realm in the Forbidden Demon Land can vaguely see it.

What's going on?

If seven different colors appear, this represents the birth of the seventh-grade spiritual liquid.

But the seventh grade spiritual liquid was born, and the seventh color was the most dazzling in the end, and it is said that the seventh color would be in the sky for several minutes.

Just as the seventh color flashing in the sky today is so dim and the flashing speed is too fast, and it has not been maintained in the sky for even a second. This is unlikely to be a strange phenomenon of the birth of the seventh-grade spiritual liquid.

But the vague seventh color did exist, what exactly is it?

...

now.

Chen Feng didn't know the doubts of the strong men in the Forbidden Demon Land.

He took out one porcelain bottle after another, placed his index finger on the mouth of the porcelain bottle, and dripping gray spiritual liquid dripped from his fingertips.

As time goes by.

The ice-type spiritual liquid dripping from Chen Feng’s fingertips has been filled with three hundred bottles.

According to his speculation, even if there is no heart pattern, according to the strength of the current heavenly fire, he can still refine about 500 bottles of spiritual liquid at a time.

After a long time.

The ice-type spiritual liquid was finally filled with five hundred bottles, and Chen Feng knew that the next one was the highlight.

Drops of spiritual liquid continued to drop out from his fingertips. He wanted to see how much effect the heart pattern could have in the amount of spiritual liquid formed?

After the filled spiritual liquid reached the six hundred bottles, the spiritual liquid dripped from Chen Feng's fingertips did not slow down at all.

Seven hundred bottles.

Eight hundred bottles.

When the amount of spiritual liquid reached eight hundred bottles, the spiritual liquid dripped from Chen Feng's fingertips finally slowed down continuously.

In the end, the spiritual liquid dripped from Chen Feng's fingertips filled 820 bottles.

Chen Feng looked at the amazing amount of spiritual liquid in front of him, and he couldn't help but take a breath in his mouth. No matter what, in terms of the amount of spiritual liquid, this simplest heart pattern definitely has an amazing effect.
