As the compression progressed, a small aura crystal gradually appeared, and it became larger and larger, gradually appearing near Tian Xu's lower abdomen, and then slowly became larger.

At the beginning, the crystal was extremely small, like a grain of dust, but as more and more aura was compressed, the volume of the crystal grew, like a needle tip, like a rapeseed, like millet, like a bird's eye...... The crystal slowly became crystal clear, and gradually flashed with golden light.

After the volume increases, the contact area between the golden pill and the outside world increases at the same time, and the speed of absorbing the aura becomes faster and faster.

Gradually, Tian Xu found that the concentration of aura around Jin Dan had decreased, and the aura in the distance flowed over to replenish, causing the overall concentration of aura in his body to decrease. At the same time as the concentration of aura in his body dropped, his body, which had already absorbed aura, began to absorb aura automatically.

The surrounding water was sucked into his lungs through his nostrils and then exhaled out of his body, while the aura in the water was filtered out by his nose and entered his body to replenish the aura absorbed by Jin Dan.

He felt that the aura in the water was much richer than usual, as if it had a tangible substance, and as it was absorbed by his nasal cavity, a small stream was formed, trickling towards the vicinity of Jindan.

The speed at which the aura was compressed into the golden pill was further accelerated, and the speed of the replenishment of the spiritual energy around the body and in the nasal cavity was already somewhat unable to keep up with the speed of the golden pill's absorption. The growth rate of Jindan began to slow down slowly.

This situation is almost impossible for other cultivators to happen. Because when ordinary cultivators are in the Qi Gathering Realm, the aura is stored in the meridians, and the thickness of the meridians, as well as the concentration of the aura in the meridians, determines the size of the condensed golden pill. At the time of compression, the aura is sucked out in the meridians by the golden pill in the lower abdomen, and the aura in the outside world is insufficient, and the speed at which the body absorbs the aura is not enough to supplement the needs of the golden pill growth. When the replenishment speed is too low, the process of condensing pills will naturally end.

The aura in Tian Xu's body had already broken through the shackles of the meridians and permeated all over his body, and the total amount of convergence was far more than that of ordinary cultivators. At this time, in the Medicine King Dou, the aura was already very strong, and the Medicine King Dou took the initiative to gather the surrounding aura to him to meet Tian Xu's needs for high-speed absorption, forming a balance of compression and absorption in Tian Xu's body.

This balance is not uniform, the head has the highest concentration of aura because of the continuous absorption of the nasal cavity, and near the lower abdomen Jindan, because of the compression consumption of Jindan, the concentration of aura is much lower. In this way, a gradient of aura concentration was formed in Tian Xu's body, and the existence of this gradient gradually began to affect the progress of Ning Dan.

Tian Xu secretly operated the Heart Purification Mantra to help the aura flow in his body. The function of the Pure Heart Mantra was really powerful, and under its influence, the flow speed of the aura was much faster, instantly making up for the dilemma of insufficient aura near Jindan.

After stabilizing the supply of aura, Tian Xu had time to observe the surrounding situation. The aura he was compressing now came almost entirely from the outside world. When Jin Dan condensed to the size of marbles, the original aura in his body had already been exhausted. In other words, without the help of Medicine King Dou, the golden pill he condensed for the first time could only be the size of a marble.

He didn't know that the first Jin Dan condensed by others was at most the size of a soybean, and his marble-sized initial Jin Dan was already able to surprise a large number of eyeballs.

At this time, Tian Xu no longer had to work hard to compress the aura into the golden pill, and the golden pill that was large enough was already able to actively absorb the spiritual qi by himself.

Inside the Medicine King Bucket, the aura was drawn from all over the place and gathered in the water near the entrance, forming a vortex of aura on the water surface. At this time, Tian Xu knew the reason why Medicine King Dou chose this place as his Ning Dan location, and the vicinity of this entrance was the most proficient position for Medicine King Dou to operate.

Despite this, as time passed, Tian Xu gradually felt that the aura from the outside world was no longer enough to meet his absorption.

At this time, Jindan had grown to the size of a walnut. Just when he thought that his condensation process was about to end, a new aura joined the whirlpool on the water, instantly replenishing the lack of aura in the water around Tian Xu.

Tian Xu's spirits perked up, and his olfactory imaging poked out of the water, and found that the Yin Yang Ding was suspended on the water above his head, and a pure aura was constantly emerging from the Ding, merging into the whirlpool.

Soon, the aura in the tripod began to fail, and among the elixirs lined up on the water surface, a thousand-year-old ginseng plant flew into the tripod, and the exhausted aura was restored to supply.

One by one, the elixir continuously flew into the Yin Yang Ding, and the spiritual energy flowed out of the Ding continuously, and was finally absorbed by Tian Xu.

Jin Dan has become bigger, already close to the size of a small egg, and the speed of absorbing the aura has accelerated again, and the Yin Yang Ding has already begun to squeeze the aura in the elixir two by two, but it is still gradually unable to keep up with Tian Xu's rhythm.

I saw that the lid of the Yin Yang Ding suddenly opened, and at once the remaining elixirs were inhaled at the same time, and then sank underwater, came to Tian Xu's side, and began to provide him with spiritual energy at close range.

At this time, the volume of Jin Dan no longer grew, but when Tian Xu looked inside, he found that the luster of Jin Dan was getting brighter and brighter, more and more transparent, like a crystal ball, very beautiful.

After the volume of Jin Dan stopped growing, the speed of the absorbed aura began to slow down, and Yin Yang Ding seemed to feel the changes in Tian Xu's body, and the output aura also changed, becoming extremely agile and lively.

After the aura entered Tian Xu's body, he was like a naughty child, wandering around curiously, driving the original aura in his body to become naughty. After being absorbed by Jin Dan, Jin Dan also became a little disobedient, as if he had some ADHD. Tian Xu ran the Heart Purification Mantra with all his might, and he couldn't completely suppress this disobedient aura for a while.

At this time, Yin Yang Ding sent an idea to him: "This is the aura of Tianxuanguo, it has its own consciousness, you have to communicate it as much as possible, and you can't forcibly suppress it." Otherwise, even if it is suppressed now, it may get out of control in the future. However, the existence of this aura can make your aura more creative, use it more flexibly, and create novel spells. ”

Tian Xu didn't expect this heaven-level divine medicine to be so peculiar, but fortunately, his Pure Heart Mantra did not rely on strong suppression, but the method of channeling, which just met this requirement.

Under the continuous effect of the Pure Heart Mantra, those spiritual energies finally calmed down, and it seemed that they had recognized him as the master, as well as the leader of the Pure Heart Mantra, no longer running around, and slowly deposited in Tian Xu's golden pill. There is still a small part that has not been absorbed by Jin Dan, and it still stays in Tian Xu's body, bringing vitality to the aura in his body.
