Xu Yi is cautious, if he is not absolutely sure, he will not easily promise.

At this time, the reason why he promised Zhang Xinxin to complete the feat of promoting to the seventh level of the human rank within two months was because he was indeed very sure.

This certainty is nothing else, it is the Heavenly Soldier Pill Furnace that he has just gotten his hands on.

This is a heavenly soldier, what a capable person can't do, is the true nature of a heavenly soldier.

When the spirit of the Dan furnace entered his sea of consciousness and communicated with him, he told about the various wonderful uses of the Dan furnace.

Ordinary Dan furnaces can only be used for alchemy.

However, when the Dan Furnace reached the Heavenly Soldier level, it was completely different.

This thing can not only be used for alchemy, but even for refining weapons, and even for refining people.

According to the spirit of the Dan Furnace, if the Dan Furnace can be promoted to an artifact, then there is nothing between heaven and earth that cannot be refined.

Of course, it seems that it is still a little far from that point.

At this time, Xu Yi entered the Dan furnace, and he immediately calmed his mind, and his mind was divided into two wisps, one concentrating his mind and urging his true qi. The other is to communicate with the spirit of the Dan Furnace and let it start to control the Dan Furnace.

The next moment, the underside of the Nadan furnace opened, and a swarthy hole appeared.

Ordinary Dan furnaces will store Dan coal here and use it for ignition. However, this Dan furnace was different, when the entrance of the cave appeared, the strange energy around it suddenly poured into it like a moth to a flame.

Immediately afterward, the fire below flashed, and it suddenly lit up.

This Heavenly Soldier Pill Furnace turned out to be fueled by spiritual energy to provide cultivation resources for the people in the Dan Furnace.

Xu Yi took a deep breath, and he keenly felt that a special energy gradually began to fill the Dan furnace.

This energy is somewhat similar to the energy of the outside world, but it is much purer and more powerful. As long as he took a breath, he could even feel that his true qi had improved slightly.

The first characteristic of the Heavenly Soldier Pill Furnace is that it can increase the essence of spiritual power, and it is not a little bit of improvement.

Although it was not an ordinary aura that permeated the Five Elements Cave, there was almost no difference before the Heavenly Soldiers.

Xu Yi calmed down and began to recite the Giant Spirit Sutra silently in his mind.

For this retreat, Zhang Pengjing had already transferred the Giant Spirit Sutra from the Ancestral Peak's Transmission Hall. It is said that this is not in accordance with the rules, but when Zhang Pengjing proposed it and promised to only use it for Xu Yi alone, Yuan Ding immediately agreed.

Moreover, hundreds of people up and down the Chuangong Hall knew about it, but none of them crooked their mouths.

Today's Xu Yi's status is extraordinary.

There were more than one hundred and eighty earth-level powerhouses in the sect at once, and the sect master even opened the Heavenly Soldier Pavilion as a reward. The exercises of the Giant Spirit Sutra are only taught...... If anyone dares to question this, I am afraid that it will immediately attract the retaliation of countless people.

More than one hundred and eighty earth-level powerhouses, each with a mouthful of spit, was enough to drown people.

True Qi was flowing in his body, and because of the endless energy replenishment from the outside world, Xu Yi didn't even need to take pills.

At the fifth level, it is also necessary to lay a foundation in the meridians.

Xu Yi's last fastest speed was to open the third pulse in seven days, but now......

"Boom ......"

There was a roar in his mind, and the temperature in the Dan furnace suddenly increased. Under this strange heat, his thoughts, spiritual power, and true qi merged with each other at this moment.

With a loud roar, a foundation was completed.

As the true qi continued to flow, the second foundation began to beat. However, at this time, at the place of the first foundation, another force is constantly impacting.

At this time, the true qi in Xu Yi's body seemed to have been divided into two. However, there is an extremely tacit understanding between these two strands of true qi, they merge into one for a while, and act separately for a while, constantly flowing in the body, and between the true qi rotations, they reach the limbs and hundreds of remains, everywhere.

When the second foundation was steady, the first foundation was already full of true qi, breaking through the pass and forming a new branching vein.

In the Dan furnace, Xu Yi was actually doing two things at the same time.

When the foundation is struck, the branch veins of the previous foundation are opened.

This approach is simply self-defeating, but in the Dan furnace, with the support of that magical pressure, Xu Yi has completed all this steadily. Although there are twists and turns, they are all thrilling and dangerous.

Moreover, within the Dan Furnace, his state of mind has always maintained a calm realm. At this moment, he forgot the time, forgot everything, and only left the true qi in his body to accumulate and grow until the limit.

Unconsciously, when Xu Yi reopened his eyes, he realized that he had completed the opening of eighteen branch veins.

Moreover, unlike before, when the branch veins were opened this time, a huge amount of true qi had already surged in, filling all the branch veins, omitting a lot of time for him to accumulate energy.

Not only that, the heat in the Dan furnace has an incredible use, and when it is accumulating, it is also constantly refining all of Xu Yi's meridians.

Xu Yi even had a feeling that cultivating in the Dan furnace was like taking the best Burning Tendon Cleansing Pill all the time. At this time, the degree of refinement of his meridians definitely surpassed that of any cultivator of the same level.

The Dan furnace at this moment is simply refining Xu Yi as an elixir, and it has also refined an innocent body.

Xu Yi retracted his mind and sensed the time. It took only eighteen days to open up eighteen branch veins.

A branch vein a day?

If this speed is spread, God knows if you want to believe it.

However, Xu Yi knew that this was also his cultivation in the Five Elements Cave, and he had a relationship with the Heavenly Soldier Pill Furnace to improve its efficiency.

How could other cultivators have Heavenly Soldiers to assist in their cultivation?

If his speed is not a little faster, then is there any reason for heaven?

In eighteen days, not only the branch veins were opened, but even his body had been adjusted to the best state.

Nineteen days, Xu Yi no longer hesitated and took out the pill.

After thinking about it, Xu Yi threw it away without hesitation.

The special Lao Tzu is now an elixir himself, and he is also the most powerful elixir, so I still need to take the elixir?

The mind began to urge, and the true qi in the body flowed again. Within the branch meridians, all the true qi felt his call, and without hesitation, they sent their savings into the main meridians.

As a result, the true qi of the main meridian passed all the way, and broke through all the passes, allowing him to reach the sixth-level realm of the human level all the way.

At the same time, Xu Yi's body also began to tremble violently.

"Ahh......h

With his screams, his body quickly grew larger, and the little giant incarnation revealed.

Even if he had prepared for it and had already enlarged the Dan Furnace in advance, it was still a little narrow.

But fortunately, the Dan Furnace Vessel Spirit has spirituality, allowing the Dan Furnace to grow larger with the little giant's physique.

Finally, when the little giant's transformation stopped, Xu Yi found that the little giant he transformed into had brought him an even greater surprise!
