As for giving the white tiger food, Liu Qian first thanked the white tiger for his protection. Second, he had a systematic practice method, and promotion was only a matter of time. The white tiger grew up with talent and opportunity, which was very difficult and difficult. In this way, the white tiger picked up a big advantage.

In addition to Zhuguo, he also got a good advantage in Red Wolf Valley. He actually found a small ore vein of black iron. According to the basic knowledge of weapon refining, although black iron is only very ordinary, or even lower-grade weapon refining materials in the entire cultivation world, it is widely used and can be used in almost many places. Besides, black iron is more than one level higher than ordinary iron. After using true fire to enhance essence, the quality of the weapons produced is also good.

The white tiger could not let it eat for nothing after eating the red fruit. Under Liu Qian's threat, he took the responsibility of a porter. After lifting out all the several tons of black iron ore, he carried the white tiger back into the cave several times. The white tiger refused to put down his arrogant airs, but his mouth was soft-eatered. After Liu Qian strongly asked that it still had no way to come out, he could only reluctantly agree to Liu Qian's unscrupulous request.

An unexpected surprise was that in the center of the black iron ore, a piece of crystal jade the size of a pigeon egg was found. This stone was extraordinary at first glance. After carefully reviewing and comparing the jade slip, Liu Qian finally confirmed that this stone was actually an unseemable immortal stone in the world of cultivation. He was ecstatic. You must know that this kind of immortal stone formed by the spiritual energy of heaven and earth is extremely rare, and usually does not grow alone. It is often accompanied by various ore veins, which is the essence of the entire ore veins. From the information, it is obvious that Liu Qian's luck this time is extremely good. The rarer and precious ore veins are, the higher the chance of containing immortal stones. However, this ordinary black iron ore vein can contain a medium-grade immortal stone, which is a great luck for Liu Qian.

The scope of the immortal stone is very wide, and it has four main uses. One is that various magic weapons need to be driven by immortal stones, and their power is doubled. Second, when practicing, you can use the high-purity spiritual energy in the immortal stone to speed up the progress of cultivation. Third, it is used as a hard currency in the entire cultivation world. The value of something is usually compared with immortal stones. Fourth, it is still used to refine magic weapons, not inlaid. Instead, after crushing the immortal stones, mixing them with other materials, greatly improving the quality of the materials in Chengdu, thereby refining better magic weapons. Of course, there are some other miscellaneous uses of immortal stones, which will not be explained one by one here.

In short, a middle-grade immortal stone is also a very good thing in the cultivation world. It is far more than hundreds or thousands of times the value of that piece of black iron ore. In any case, Liu Qian would stick this treasure to his chest and hide it. A stream of thorough and cool feeling spreads out of his chest and spreads throughout his body. With his spirits excited, his mind feels clear.

After finishing his work, the White Tiger hurriedly got into his own hole and digested the benefits of the vermilion fruit. Liu Qian's most important job at this time was to extract the black iron from the mine first.

Originally, according to the art of refining, the refining of this kind of ore was usually just thrown into the furnace. However, now Liu Qian is poor and has no furnace? Ordinary furnaces made of iron are simply useless. At least they need things like black iron to make furnaces. In desperation, Liu Qian could only rely entirely on his own. He first made some square touch tools with stones. Then, he refines the ore piece by piece by piece by piece by piece by piece.

After all, black iron is different from mortal iron. Liu Qian's first taste of true fire, it takes more than half an hour to melt a piece of black iron ore the size of a head. And the black iron extracted in this more than half an hour is just not as big as a fist.

Half an hour of continuous use of true fire is now the limit of Liu Qian. Only after meditating and recovering his true energy can he start work again. Fortunately, this is also a method of exercise, otherwise Liu Qian would not be able to stand this boring work.

A month later, several tons of black iron ore were finally initially refined, and finally more than 200 kilograms of black iron were formed. At this time, Liu Qian also grew from supporting half an hour to supporting about fifty minutes. Grandma's weapon refining technique is indeed a good method of practicing. Seeing his own progress every day, Liu Qian couldn't help but start to be proud. However, the white tiger did not come out for a month as soon as it entered the hole. It is estimated that if it comes out again, it will have an extraordinary effect.

After cleaning up the debris, the next step is to refine the black iron again, remove its impurities, compress the volume and increase its density. It took more than two months to comb all the black iron nine times. The weight of the black iron did not decrease much, but the volume was one-half smaller. The inconspicuous piece of black iron, the size of a brick, was so heavy that it was shocking when I held it in my hand.

The black iron of less than 200 kilograms is not much in size together, so there will definitely be no chance to make a furnace. You can only make a hammer and a long knife. The hammer is easy to make. Make a mold and melt it and fill it up, and add a wooden handle.

But the knife is different. After spending more than a month, it melted three times. It was finally made Liu Qian feel satisfied. A saber with a thick back and wide blade was freshly released. The following days were to keep heating and pounding. This method was not only to create satisfactory knives, but also to be beneficial for cultivation. Every time I exhausted the innate true qi, I meditated, and the effect was even more obvious, especially the effect of the immortal stone. In just half a year, Liu Qian almost promoted from the early stage of the innate stage to the middle stage of the innate stage.

The cultivation time of the innate realm is so long that it is unbearable. Many innate masters with extraordinary qualifications may not be able to break through the realm and form a golden elixir for a life span of 500 years.

The blade was shining with a faint cold light under the sun. In total, it took half a year to finally succeed. Liu Qian held the wide, thick but murderous slashing saber, condensed his energy and gathered his spirit, and stood tall against a huge rock.

After a long time, he shouted in a deep voice. The slashing sword slashed away with a slight scent of the aura of Xiaoxiao. The extremely good true energy penetrated through the knife. It formed a faint half-moon arc-shaped knife energy, which broke out. With a loud bang, the rock cracked from it and divided into two halves.
