If there were no large number of pills, resources, and so on, the time required to cultivate Lao Jun's Open Heaven Sutra to an extremely high level might be dozens or hundreds of times that of other exercises.

Of course, if the resources are sufficient, then it can be full of firepower, constantly refining all kinds of heavenly and earthly treasures, itself is like a huge furnace, constantly throwing in fuel, the fire is burning more and more, and the smelting speed will be faster and faster.

In this case, the cultivation speed will be quite terrifying, and it will be much faster than ordinary exercises!

After thoroughly understanding this Laojun Open Heaven Sutra, Chu Tianlin began to use the sect's points to buy medicinal materials, and then refined the pill again, what Chu Tianlin wanted to do was to make a lot of alchemy, convert the successfully refined pill into points, and then use the points to buy medicinal materials.

He had to prepare for a retreat that lasted for more than a year, and in this process, he first had to prepare himself a sufficient amount of pills for his practice, and then he would practice Lao Jun's Heavenly Sutra to an extremely high level at one time.

And because of Chu Tianlin's crazy alchemy and selling it, in just one month, the price of the pill that had not changed greatly in the entire Earth Sect for hundreds of years had generally dropped by as much as thirty percent.

It can be seen from this that Chu Tianlin has made the number of pills refined by Duoduo be terrifying, otherwise, it would not have had such a terrifying impact on the value of the pills in the huge market of the Earth Sect.

And a month later, Chu Tianlin also accumulated a full 800 million sect points, and then exchanged all of them for medicinal materials.

It's not that Chu Tianlin thinks it's enough, but the medicinal materials in the inventory of the entire Earth Sect and the medicinal materials in the hands of the sect's disciples have all been purchased by Chu Tianlin above the eighth or ninth floor, so Chu Tianlin finally decided to start the retreat.

Those medicinal materials were all thrown into the creation furnace by Chu Tianlin, and let Duoduo follow the prescription. It is slowly refined into various elixirs.

And every time Duoduo successfully refines a pill, Chu Tianlin eats a pill, and the process of refining the pill requires the consumption of Chu Tianlin's aura, and Chu Tianlin will turn into a furnace in the process of practicing Laojun to open the Heavenly Scripture. Constantly purify the aura.

In this process, a large part of the aura will be discharged by Chu Tianlin's body as waste gas, and Duoduo is using this part of the waste gas to refine the elixir.

In other words, the more exhaust gas excreted from Chu Tianlin's body, the faster the speed of Duoduo alchemy, and the faster the speed of Duoduo alchemy, the more pills supplied to Chu Tianlin, and naturally, the more exhaust gas was discharged from Chu Tianlin's body.

It's a virtuous circle that complements each other. With the passage of time, Chu Tianlin's cultivation of Lao Jun Kaitianjing continued to improve, and Chu Tianlin's strength was also rapidly improving, and the speed at which he swallowed the pill was also constantly rising.

And Chu Tianlin's preparation is also quite sufficient, after all, if he is an ordinary disciple, he does not consider bottlenecks in the cultivation process. The pills he needed to consume during the entire cultivation process were about 100,000 points of pills.

And if you transform this elixir into medicinal herbs. It only requires five thousand points of medicinal materials, after all, there is a big difference between medicinal materials and pills, and from medicinal materials to pills, it needs to be refined by senior alchemists, and there is a possibility of failure in the process.

And the high-level alchemist is not so easy to make a move, and Chu Tianlin. Prepared a full 800 million sect points to buy medicinal materials.

In other words, the medicinal materials purchased by Chu Tianlin were enough for 160,000 disciples to ascend from a mortal to a mortal peak approaching the peak of the celestial Cheng Dù without ignoring the bottleneck.

It's no wonder that Chu Tianlin actually wiped out the inventory of a huge three-grade sect. That's 160,000 servings of the elixir!

Therefore, Chu Tianlin only then had the confidence to retreat and practice, and in one breath he practiced this Laojun Open Heaven Sutra to the top Cheng Dù, in the process of practicing Lao Jun Open Heaven Sutra, Chu Tianlin could feel that he had become a furnace.

And at the beginning, the furnace that it transformed into itself burned with a red flame, and as time passed, the color of this red flame became brighter and brighter, and gradually there was a hint of gold, and the red in it became less and less.

After reaching a certain limit, the color of the flame changed to completely golden, golden, golden flame, the temperature of the flame was significantly higher than the previous red flame, and the speed of smelting the aura and the process of refining the aura were also greatly improved.

And after the flame turned golden, Chu Tianlin's speed of swallowing the pill also increased by more than five times, and then, Chu Tianlin continued to swallow the pill continuously.

And the gold in this flame gradually added wisps of blue color in the gold.

If it was said that the golden flame before was refining and refining the aura with a terrifying temperature, then this wisp of blue in the golden flame was no longer aimed at the aura, but directly against the elixir.

When the flame was golden before, Chu Tianlin swallowed the elixir, and then Chu Tianlin's body digested it and gradually released the aura, and the aura released by the elixir was smelted and absorbed by the golden flame.

And now this dark blue flame did not wait for Chu Tianlin's body to digest the pill, and did not wait for the medicinal power of the pill to be released, so he directly pounced, and then, the dark blue flame directly devoured the pill, and then quickly released the aura of the pill, and purified and smelted it.

And the color of the aura in Chu Tianlin's body is also constantly changing, the aura absorbed from heaven and earth was originally milky white, but after the first refinement of the red flame, it became a color close to transparent.

It's just that this is not the color of the extremely pure aura between heaven and earth, the reason why it is crystal transparent is because after refining, most of the aura is expelled from the body, and the concentration of pure aura in the body is too low, so it will be close to transparent.

As the number of pills swallowed by Chu Tianlin increased, Chu Tianlin's body was filled with silver aura, and after that, the flames of Chu Tianlin's body furnace were transformed into gold, and these silver auras gradually changed again, and finally the silver aura was transformed into a light blue color.

Wisps of light blue aura flowed in Chu Tianlin's body, more beautiful than the previous silver aura, and full of vitality, and after the flames in Chu Tianlin's body turned dark blue, the light blue aura in his body gradually became viscous. However, the color of the aura has not changed in any way, and it is still light blue. (To be continued......)
