In these two aspects, Li Tong had no experience at all, and he suddenly became a little blind.

"Didi...... Master, you can use the method of preaching to learn alchemy! You only need to consume the contribution degree! To upgrade to the master-level alchemy, you only need 500 million contribution degrees!" Pipiru's voice sounded in Li Tong's heart, and Li Tong's eyes suddenly lit up.

yes, how did I forget about it!

He found alchemy in the miscellaneous section of the Divine Doctor Mall system, and learned it casually, and in an instant, Li Tong entered a real dream.

In the dream, he was an alchemist, who came out of a small family that was not famous and entered a large sect. From the medicine boy, to the first-order Dan Master, and then to the second-order ...... He has grown to the fifth-order alchemy master, and his brilliance has shrouded the entire sect, and everyone will respectfully call him after seeing him: Ancient.

Fifth-order alchemy master, all eyes are on him.

Skillful manipulation of flames, skillful purification of medicinal herbs. Everything flowed smoothly, without a trace of stagnation or thought, as if these things had become his instinct.

There were constantly noble people who came to the door to ask for medicine, and Li Tong did not refuse, he had a faint feeling that he needed a large amount of refining pills, as for why?

He just knew that he had to do alchemy. Whether it was a first-order pill or a fifth-order pill, he had to refine it. Refining again and again, familiar again and again.

That's it, a hundred years have passed. Li Tong was dying, and until the last moment of his life, he still didn't understand why he was refining the pill again and again?

Never-ending refining, as long as others ask for medicine, he doesn't know how to refuse.

"Perhaps, this is fate!" The old Li Tong sighed, and then closed his eyes, and at this moment, Li Tong in the Pure Land opened his eyes, and a touch of vicissitudes came to his face, and everything here made him a little strange.

So much so that the pupils of the eyes seem a little sluggish.

But soon, Li Tong woke up, and the previous hundred years were just a dream for him. It's just that this dream is so clear that he thinks it's true.

Is this preaching?" muttered to himself.

"Didi...... Master, this is because the level of the absorbed crystal skull is not high, otherwise, once you preach, even if your alchemy technique reaches the realm of a divine master, it is possible from time to time!" Pipiru said with some excitement, "The system has this kind of change, or thanks to that crystal skull, I'm afraid even if the old master is alive, I have to admire." ”

Hearing this, Li Tongwan smiled, although he didn't know what the mystery of the crystal skull was, but since the other party was able to upgrade his Divine Doctor Mall system, he would naturally have to grab more in the future.

Dan Dao!

Broad and profound, in ancient times, some Dan Dao masters were unable to study this Tao thoroughly in their lifetimes. Li Tong got the help of the Divine Doctor Mall system, and with the means of preaching, he spent hundreds of years in his dreams before he passed on these Dan Dao to the master realm.

At this time, Li Tong went to look at the Dan Fang of the Yang Dan again, and his eyes suddenly lit up, and he saw at least three times more mystery than before he preached.

Li Tong was glad that he had this kind of Dan Dao inheritance, otherwise, even if he had gathered enough medicinal materials, he would not be able to refine this Yang Returning Pill at all.

Although this pill is a fourth-order pill, because of its special effect, it can make people return to the dead and yang. Therefore, its complexity is even more cumbersome than that of a fifth-order elixir.

However, after receiving the preaching of Master Dan Dao, Li Tong already had an idea in his heart about how to refine the Returning Yang Pill.

Glancing lightly, he only had 130 million left, and he had only 130 million of his contribution saved up to 600 million after receiving twelve Yin Evil Beasts in the capital of the Northern Capital, and he wanted to use this to upgrade the space-time dragon spear into a treasure of the Heavenly Dao, but now it seems that it has to be postponed again!

However, after learning alchemy, Li Tong can try to refine some pills by himself, such as his own spiritual rice, spiritual fruits and vegetables, extracting substances containing immortal properties, refining them into pills, and saving a big bowl of food.

As soon as he thought of this, with his more than 100 years of alchemy experience in his dreams, he naturally thought of several longevity pills that could be refined, and he was immediately excited.

But now is not the time to think about that, it's better to refine the Huanyang Pill first.

Li Tong took out thousands of medicinal materials, and his ten zhang divine sense shrouded these medicinal materials, which immediately made Li Tong aware of it. He took out the incinerator and placed it directly on the ground.

Li Tong's whole body qi and blood were like an ocean, instantly urging the incinerator to ignite. The flames of the furnace rushed up into the night, as if they had turned into a thousand divine flames in an instant.

"Divine fire is divine fire, I don't know how many times more powerful than mortal fire!" Li Tong muttered to himself, and the divine fire soared into the sky, directly sweeping ten kinds of medicinal materials into it. The medicinal materials tumbled, and Li Tong's divine consciousness was directly shrouded in the divine flame, and the raging flames, under the control of Li Tong's divine consciousness, turned into a very small flame, and at the same time purified the medicinal materials.

One by one, the purified medicinal materials were put away by Li Tong, and then the remaining medicinal materials were purified again.

This is a delicate and tedious work, and ten kinds of medicinal materials are purified at the same time, which is too demanding for the divine sense. It is also the ultimate that Li Tong can do at this stage.

Thousands of medicinal materials were purified, this was not an overnight thing, even if Li Tong's cultivation had reached the Forging God Realm, it was also an overloaded task.

For ten days, Li Tong seemed to have fallen into a mechanical state. He sat cross-legged on the ground, the fire in front of him was blazing, and one kind of medicinal herb after another was sent into the incinerator, and after a while, the purified medicinal herbs would be taken out of it.

Li Tong seems to have fallen into a realm of selflessness.

This kind of state was rarely encountered by him when he was refining pills in his dreams before, and it was called the Dan Realm. It represents the supreme state of having only one mind and no distracting thoughts.

In this kind of Dan realm, the alchemy of the Dan is rare, and there are few failures.

Li Tong's fingers were on fire, and his heart was like a cheerful flame spirit in his hands, purifying medicinal materials like flowing water. Until the thirteenth day, a thousand kinds

The herbs have been purified.

These medicinal materials are enough for Li Tong to refine two furnaces of Huanyang Dan.

Li Tong took a deep breath, and the whole person once again entered the kind of Dan realm where things and I forgot about them, and the purified medicinal materials were put into an ancient tripod by him, which was one of the three tripods of the original lock dragon array, and this tripod has already produced spirituality, and it can be said that it is twice the result with half the effort for alchemy.

One after another medicinal materials were put in, and all of Li Tong's divine consciousness was integrated into the Gu Ding, carefully controlling the fusion of various medicinal effects.

Thousands of medicinal herbs, although they have all been purified, are definitely a big burden for the divine sense.

Poria cocos, goldenrod, ginseng root......

Countless precious medicinal materials were integrated into the ancient tripod by Li Tong little by little, the aura was rolling, the furnace was blazing, and the walls of the ancient tripod were burned into cyan.

A month has passed, and Li Tong is in the Pure Land, and his hair is like crazy. During this month, his consciousness was highly exhausted, and his whole spirit was on the verge of collapse.
