For Jiang Xincheng, the best way to consolidate the realm at present is to refine the pill and use the pill to help him consolidate the cultivation realm, so that he can save a lot of time and consolidate the foundation of cultivation as quickly as possible.

As the first alchemist of the earth, how could he waste them in vain in the face of all kinds of heavenly and earthly treasures all over the earth.

After careful consideration, Jiang Xincheng chose the elixir he wanted to refine.

Seven alchemy!

The first-grade spirit pill, after taking it, can temper the dantian and meridians, temper the vain cultivation foundation extremely strong, and consolidate the current realm.

Not only that, in addition to tempering the cultivation foundation, the Seven Alchemy Pill can also temper all parts of the body, so that the physical strength of the Yuan Shi can also be increased a lot, but compared to the tempering and consolidation of the cultivation foundation, this effect is nothing.

Now that he had determined the spirit pill he wanted to refine, Jiang Xincheng didn't delay any longer, and immediately left the dormitory, taking the only hundreds of credits he had, to buy all kinds of spirit grass and materials he needed.

After the Fourth World War, the whole world was divided into three major forces, the Shenxia Alliance, the Non-War Pact Organization and the Mowei Empire, for the convenience of currency, the three major forces abolished all kinds of coins in the past, and all changed to credit currency, referred to as credit currency, also known as credit, which can be used all over the world.

Credits can be stored in a bank card or cashed out as currency, circulating around the world and making them easy to use.

Fortunately, there are no other alchemists on the earth now, and no one grabs these alchemy materials with Jiang Xincheng, so these alchemy materials are extremely cheap, how can they be like the later generations, and the materials of the first-grade spirit pill are expensive to death, at least thousands of credits.

The only expensive material in the Seven Alchemy is the main material Seven Iron, which is tempered into steel, which means that iron can be tempered into steel only after a hundred times, of course, it is only an imaginary number, and iron is not tempered a hundred times to become steel.

And the seven iron refining must be tempered seven times of iron, and it must be tempered by Yuan Li, not more nor less, Tianhai City is an international metropolis, naturally there is no blacksmith shop like ancient times, so Jiang Xincheng can't go to the blacksmith shop to create any seven iron.

However, Jiang Xincheng has his own way, he went to buy a set of old iron-striking equipment, and only spent five hundred credits, preparing to make seven iron refining by himself, in his previous life, Jiang Xincheng was a fourth-level alchemy master, and he didn't know how many seven alchemy pills had been refined, and all kinds of materials were made by himself, so he was also quite proficient in the refining of seven iron smelting.

Except for this set of old iron-striking equipment, which is a little more expensive, everything else is very cheap, not to mention iron, you can pick up a bunch at random at some garbage dumps, and you can't take it all.

Another material of the Seven Alchemy Pill is a hundred-year-old tree root, it is not difficult to find it, you don't need to spend a penny, go to a well-preserved ancient garden in Tianhai City and go around, Lu Jingwei has an extra pound of hundred-year-old roots in his pocket, but he just paid a dozen credits for the entrance fee.

There are also some other scattered spiritual grasses and materials, which only cost Jiang Xincheng more than 100 credits, which is really cheap and cannot be cheaper, so that Jiang Xincheng can fully enjoy the advantage of being at the forefront of the world.

You must know that if it is changed to the future generations, this pile of materials will cost at least tens of thousands of credits, especially the hundred-year-old tree roots, which are simply expensive to death, how can it be like now, you can get a bunch at will, and no one will grab it with a knife or a gun.

The iron-striking equipment and all the materials cost Jiang Xincheng a total of more than 600 credits, and he still had more than 200 credits left, and he used more than 100 credits to rent a remote old house, Jiang Xincheng put everything into the old house, and prepared to refine the Seven Alchemy Pills.

Tianhai University is located in the suburbs of Tianhai City, renting is extremely cheap, the single room near the school is only more than 200 credit points a month, not to mention that the old house rented by Jiang Xincheng is several miles away from the school, and it is still an old house in the countryside, and more than 100 credit points are a bit expensive a month.

Jiang Xincheng also saw that this place was extremely secluded, the environment was not bad, there were no people around, and his secrets would not be easily discovered, so he rented here.

After supporting the iron-striking equipment very well, Lu Jingwei made a charcoal fire and began to prepare the first material of the Seven Alchemy Pills, which is also the main material of the Seven Alchemy Pills, the Seven Iron Smelting.

The furnace was blazing, and Jiang Xincheng used Yuan Force to seduce the Yuan Force in the coal, generate the fire of Yuan Force, and began to quench pig iron.

There is Yuan Force in all things on the entire earth, and there are almost no things that do not contain Yuan Li, and it is not an exaggeration to call the Earth a Yuan Force Planet, but under normal circumstances, the Yuan Force contained in these things is silent and will not be released.

Human beings have survived on the earth for tens of millions of years, and the history of civilization has been thousands of years, but over the years, human beings have never discovered the Yuan Force, nor can they use the Yuan Force in all things in heaven and earth, but they just use all things in heaven and earth full of Yuan Force in the roughest way, wasting too many precious high-grade Yuan Stones.

However, even now that the Yuan Force has been discovered, people don't know how to use the Yuan Force contained in all things in heaven and earth, and they are still using all things in heaven and earth in the most efficient way, and only Yuan Jing humans can use it better.

If people don't use a special way to stimulate the Yuan Force in all things in heaven and earth, all things in heaven and earth are ordinary things in heaven and earth, not some precious high-grade yuan stone.

For example, rice, if it does not hook the Yuan Force and stimulate the Yuan Force in it, this rice is just ordinary rice that can eat a full stomach.

However, if the Yuan Force in it is stimulated, this rice is a third-grade Yuan Stone that can put ordinary Yuan Force cultivators to death, and after ordinary Yuan Force cultivators absorb the Yuan Force in it, the Yuan Force is not pure, and it takes countless time to refine and purify, otherwise the foundation will be unstable, and the Yuan Force in the body will be ****, and the body will explode and die directly.

Time passed, the flames were raging, Jiang Xincheng took off his clothes and hammered hard.

Again......

Second time......

Three times......

……

It wasn't until the seventh time that the Seven Iron Smelting was officially formed, looking at the Seven Iron Smelting in front of him, Jiang Xincheng was full of smiles, with the seventh-grade high-grade coal yuan stone quenching, with his decades of experience, plus a little luck, he actually created an extremely precious high-grade Seven Iron Smelting Material, and now he should be able to refine a lot of precious Seven Alchemy Pills.

Smiling slightly, Jiang Xincheng put away the equipment for striking iron, such a large piece of seven iron refining is enough for him to refine the seven refining pills a hundred times, and there is no need to make seven iron refining for the time being.

The main materials of the Seven Iron Refining and the hundred-year-old tree roots are all complete, so the next step is to refine the Seven Alchemy Pills of the first-grade Gongji Lingdan, once the Seven Alchemy Pills are refined, the problem of unstable foundation will be solved immediately, and Jiang Xincheng will be able to impact a higher realm.
