The reason why he opened this restaurant was not to be idle and bored in this world, nor was it to use his alchemy techniques to benefit the public.

It's for the source.

According to the description of the original book, in the distant primeval era, when all things were born, there was plenty of aura, and every grass and tree contained a large amount of life essence.

Many creatures are able to freely absorb the vitality of heaven and earth, forming amber-like crystals, which contain a large amount of life essence.

Over time: these crystals settle down, forming a source.

And during that period, strange flowers and fruits were everywhere, so there were many rare divine sources left.

Each piece of divine source may contain ancient treasures, and some people even prescribe exercises in it, or the corpse of the primeval royal family, or a certain ancient demon.

It can be said that open source is gambling, betting on whether it is scrap iron or precious gold and silver. This is similar to Lu Li gambling on stones on the earth.

Lu Li's main purpose is actually for these things.

The divine source contains a large amount of life essence, as well as the essence of heaven and earth. It is a very suitable material for alchemy.

Moreover, the divine source may also contain the corpse of the ancient demon, and these things can also be taken to the three-legged golden crow to eat.

Of course, this is not to eat corpses, the ancient demon clan or the primeval royal clan their vitality is very strong, plus the divine source is closed and contains a lot of energy, their vitality and the freshness of the corpse will be completely preserved.

Some divine sources can even be resurrected on the spot as soon as they are opened, which shows how powerful their vitality is.

The cultivation of the three-legged golden crow at its peak is equivalent to the primordial golden immortal, due to the fact that it has been sleeping for many years, its own strength has fallen to the void Xuan Immortal of the Cave True Dao, and there is a large deficit of qi and blood, and it cannot maintain a huge state for a long time, and it has been in this chicken-like body shape for a long time.

The reason why these things are thrown out now is to make the name of the restaurant, and then throw more fierce things in exchange for the divine source.

The number of places in the restaurant was already in short supply, and the Supreme Elders of some sects and the Holy Lord personally came to woo them, but Lu Li was unwilling to give them places.

As a modern person, Lu Li knows the concept of hunger marketing, and only with a limited number of places will the forced qualifications be high, and more people will be sought after.

Lu Li was also the shopkeeper during this time, and handed over the cooking to Zhang Ziling, and he didn't care about the rest, since that day he slapped the Supreme Elder who came to the door to seek revenge, and the Holy Lord behind him, no one around here dared to provoke him.

At this time, Zhang Ziling came to the courtyard.

"Ten spots over?" Lu Li asked.

"Yes, we've made tens of millions of dollars in the past month." Zhang Ziling said excitedly.

With tens of millions in hand, you can go sideways in this city.

Lu Li didn't speak, he didn't pay attention to these things, they were just ordinary sources, and they were only a few hundred catties when converted into divine sources.

Lu Li glanced at Zhang Ziling up and down, and said, "Are you preparing to practice?" It takes a lot of energy to practice, and you can use these sources, and it's a waste to put them anyway. ”

Cultivators and immortals need to get through the knots, such as the True Sutra can open up one hundred and eighty knots in the body, Lu Li felt that it was not enough, so he simply gave him all three hundred and sixty chakras of life and death in the heavens, in this way, it would take a huge amount of energy to get through.

However, these energies do not matter, and can be replenished by absorbing the life essence in the source.

"By the way, are all the medicinal herbs and golden stones I asked you to collect ready?"

"Ready."

Lu Li plans to open a furnace for alchemy and refine a furnace of Dragon and Tiger Pill.

The dragon and tiger Dan yin and yang converge, and the five elements are complete. The alchemist is called Waidan.

Legend has it that mortals who take this pill can become immortals on the ground.

Of course, this is obviously a false rumor by mortals, the Dragon Tiger Pill contains a large amount of heavy metal toxicity, there is no mana refining, and if you eat it, you will be poisoned on the spot.

These things are all prepared for cultivators, and when Lu Li broke through, he refined one, and only by combining the inner and outer pills could he become an earth immortal.

Now after breaking through the Spirit Yuan Creation True Immortal, refining this furnace pill can be regarded as handy.

Lu Li planned to practice eighteen pills this time, and these pills were something he would use to trade in the future.

Lu Li was busy cultivating all day long, and he didn't have time to look for things one by one, so he could only use the fame of the restaurant to let people keep bringing good things, which was the most convenient form.

Lu Li is not afraid of the masters of this world, but he is just afraid of trouble.

After Lu Li got the materials, he stayed in the back room and prepared to retreat for alchemy.

Three flavors of true fire rose inside the three-legged and two-eared alchemy furnace, Lu Li threw the materials into it, and under the baking of the blazing fire, it turned into a lump of golden liquid, and the impurities of the elixir continued to be refined, eventually leaving a ball of pure "nature".

Although the name of the pill has a medicine word, it is not medicine in the real sense, and the alchemy is a refining word that stands out.

In essence, Huaxia's chemistry actually originated from alchemy.

The principle of alchemy is actually similar to chemistry, which is nothing more than refining the active ingredients and removing impurities.

For example, lead and mercury contain yin and yang. Gold represents immortality.

How to remove the chaff and refine the nature. This process is called alchemy.

In the process of alchemy, I understand the rules, the five elements of yin and yang, which is called Zhengdan.

The materials used in alchemy are actually not very rare, but they have very powerful powers.

Many people don't understand why the elixir refined from not too valuable materials is more powerful than the elixir that has been grown for tens of millions of years.

In the case of false rumors in the world, alchemists are believed to have the means to "turn stones into gold".

In fact, the alchemists' methods are even more powerful than turning stones into gold, because they have already touched the essence.

No matter how miraculous the magic medicine is, chasing its essence, it is just a certain ingredient at work.

As long as the alchemist finds out the ingredients, he can simulate and reproduce them through other materials.

The medicinal power of tens of millions of years of magic medicine can be reproduced by people through a few less expensive materials, which is the ability of an alchemist.

To put it simply, the alchemist is actually the immortal version of the "scientist".

A month later, there was a loud bang in the Dan furnace.

Bang! A puff of purple smoke wafted out from the vent of the Dan furnace lid.

The sky was blue for a hundred miles, and the purple qi was in the sky, and countless birds flew from the sky, devouring the purple qi in the sky, and the size of these birds became larger at a speed visible to the naked eye.

Eighteen golden pills flew into the air, and then they were sucked back by a burst of suction, and the vision disappeared.

"Born with a vision, is there a secret treasure born?"

The surrounding masters all looked in Lu Li's direction, and the look of shock in their eyes was thick.

With such a powerful energy, could it be that the ancient magic medicine was born?

For a time, countless forces were surging. There is a restaurant with information on the desks of the big guys.
