Mao Qing replied to Ye Yu's message with a messenger, telling him to be more careful, during this time he seemed to have some understanding that he had been in retreat for a while, and was ready to go to the depths of the small world, unless he encountered something very urgent and came back to him.

After Mao Qing sent this message to himself, Ye Yu knew that Mao Qing would have a big entry during this time, and in the memory of his previous life, Mao Qing had also disappeared for a period of time, and when he appeared again, he was saved from several cultivators in the refining period, and he could still have the upper hand with one enemy and three enemies.

Moreover, it seems that the best treasure Dan Furnace can also exert its due combat power in his hands, and the magic weapon Dan Furnace is essentially stronger than other magic weapons.

Therefore, Mao Qing can defeat three with one, and he has to overwhelm three people.

Early the next morning, Yin appeared on the roof of the Fengyun Building.

After Ye Yu explained that he protected Zhao Liya, he was ready to go.

The primary target is gold and iron, a mysterious substance born in lava, in his previous life, Ye Yu's natal magic weapon was not created by himself, but obtained in a mysterious cave, because he was besieged at that time, so he broke into that cave by mistake.

But it happened to be engraved with the words of the earth, and he could understand that it was a treasure left by the immortals of the Guigu Valley and given to the destined person, and this "destined person" seemed to have a special requirement, that is, from the other end of the starry sky, the earth.

And Ye Yu just met this condition, so he accepted the inheritance of the Ghost Valley Immortal without any hindrance.

Originally, there was a Taoist priest named Guiguzi in his own country, who was good at strategy and calculation, and originally Ye Yu connected the two, but after seeing his inheritance, Ye Yu dispelled his thoughts.

Because the inheritance left by the immortals of this Guigu Valley does not have anything related to Taoism, it is all related to alchemy and refining magic weapons.

At that time, the alchemy furnace was actually just a defective product, and it seemed to be a failed exploration by the Ghost Valley Immortals, so at first, Ye Yu thought that this alchemy furnace was actually not as strong as he imagined.

It wasn't until later that he accidentally fused the Divine Fang with the Dan Furnace on a way to be chased and killed, that he discovered the power of this Dan Furnace.

Therefore, Ye Yu planned to find the two treasures of gold essence iron and heavenly crystal first, and then find a way to find out if there was any divine appearance in the star field where he was located.

Taking the Sima family's helicopter, in less than a few hours, Ye Yu came to the top of the Longgang crater, the largest volcanic crater in China, looking at the churning magma below, Ye Yu opened his spiritual sense to investigate, and sure enough, a large amount of gold and iron was found at the bottom.

So Ye Yu took the tools he brought from the plane and dug from the bottom of the volcano, and after several hours of hard work, he finally dug up the gold essence iron at the bottom, because only his own natal magic weapon needed this material, Ye Yu also took the part he needed.

Celestial crystals are generally difficult to find, but Ye Yu knows where it generally exists, either close to the inner parts of some planets, or some will be produced in places that have been frozen for 10,000 years.

In his previous life, after he arrived in the fairy world, he found the celestial crystal on some 10,000-year-old snow-capped mountains, as for the core of the planet, the spiritual sense of the general immortal can almost detect the core of a relatively small planet, of course, the higher the cultivation, the more it can be detected.

Now, although Ye Yu has the soul power of the middle stage of the Heavenly Immortal, his own cultivation is too low, even if he knows that there is a celestial crystal in the core of the earth, he can't dig it out.

Besides, if you really want to dig up the celestial crystal, wouldn't it be to open a hole for Mother Earth.

It's a bit too unkind.

The southern polar region of the earth has existed since ancient times, and its history may be more than tens of thousands of years old, Ye Yu has every reason to believe that there must be a celestial crystal over there.

But now the whole world is not allowed to fly to the southern polar regions, because the various electromagnetic waves generated by the planes may interfere with some organisms and other visible materials in the southern polar regions.

But who is Ye Yu, he is the former Immortal Emperor, of course, he drove a helicopter to the southern polar region by himself without fear.

He was a monk and could use his own means to extract oil directly from some of the ground, and in less than three days he flew to the polar regions. After a while, he found the celestial crystal at the bottom of an icy mountain, and after taking it, he returned to Huizhou.

If anyone knew that he had made a trip to the southern polar region in a few days, their jaws would drop in shock.

Back in Huizhou, Sima Yan provided a site on the outskirts of Huizhou for Ye Yu, and the materials were all found, Ye Yu also recalled the previous refining method, and forged, bleached, and quenched all the materials step by step, and finally refined them into shapes.

After half a month of hard work day and night, and after his pills were almost consumed, Ye Yu finally succeeded in creating his own natal magic weapon: Hongmeng Qiankun Furnace.

This name was not taken by Ye Yu, but left by the Guigu Immortals, probably because he failed at that time, so the name of this Dan furnace was not known in the immortal cultivation world.

But since Ye Yu began to cultivate it, almost everyone in the immortal cultivation world knows about it, and everyone knows about it, because Ye Yu has used it to challenge many times, and he has been surrounded and killed many times to escape and ascend to heaven, and everyone is a little afraid when they mention it.

Shrinking the entire Dan furnace and receiving it in his hands, Ye Yu felt the feeling of integrating his natal magic weapon into his body. There was a burst of joy in my heart.

The people of the Immortal Realm are waiting for me, your Creation Immortal Emperor, the Immortal Venerable, will soon come back again to dominate the entire Immortal Realm!

The Dan furnace has been refined, the next step is to refine the pill, in addition to some necessary pills, Ye Yu also has to refine the Robbery Avoidance Pill promised to the Ruan family, and this Tribulation Avoidance Pill Sima Yan can also be used.

He is about to break through to the Golden Pill, and he can temporarily avoid the Thunder Tribulation by taking a Tribulation Pill, and when his cultivation is stable within a year, there will be nothing to be afraid of when the Tribulation comes.

The two Mulan pens can use the best treasure Dan furnace to refine about twenty-five Pills of Avoidance.

But at that time, Ye Yu's cultivation was too low, although the quality of the Dan furnace was high, Ye Yu could not use it, and now his own Dan furnace was formed, although it was only a low-grade talisman, but Ye Yu was also handy to use, and with the help of different fires, the efficiency of alchemy and the probability of becoming a Dan increased significantly.

After a while, a burst of medicinal incense wafted out, and countless dodging pills slowly erupted from the Dan furnace, Ye Yu probably counted them, and he actually refined as many as thirty pieces!
