Ma Fan took out the black gold from his travel bag and planned to start refining the Dan Furnace. The Black Gold Pill Furnace is only the most ordinary Dan furnace in the Haotian Continent, and almost all of the black gold pill furnaces used by entry-level alchemists are generally used. However, since there are not as many Dan masters on the earth as there are in the Haotian Continent, and no one has mastered the refining method of the Black Gold Pill Furnace, it has never appeared on the earth at present. Even the so-called alchemists who appeared in the pre-Qin period only used bronze tripods and could not withstand relatively high temperatures. Ma Fan thought about it, but still felt that it was appropriate to lay out an isolation formation first. Refining the Dan furnace, as well as refining the pill in the future, will be accompanied by sounds, high temperatures, and fires, Ma Fan now lives in an ordinary residential community, and he doesn't want to make such a big move.

So, Ma Fan took out the smaller piece of jade, gathered his right hand into a blade, and quickly cut off a few small pieces of jade. Ma Fan put the jade on the floor, made a seal with both hands, and kept carving the formation patterns on it. About a quarter of an hour later, a burst of bright light flashed on several pieces of jade, and then the bright light disappeared immediately. Ma Fan placed several pieces of jade in several directions, then sat cross-legged, sealed his hands, and laid out a hidden formation, and the last few pieces of jade suddenly disappeared.

The two formations are complete. An isolation formation can isolate sound, light, and heat within a certain range, and this formation is often used in Haotian Continent competitions and new weapon tests. Of course, the higher the level of the formation, the greater the energy field that can be isolated, and the other hidden formation can hide the item, but the item is actually still in place, but it cannot be detected by the naked eye and induction.

Now, no matter whether the bedroom is an earth-shattering noise, a scorching heat, or a dazzling glare of bright light, it is impossible for people outside the bedroom to feel it.

Nodding with satisfaction, Ma Fan began to refine the Black Gold Pill Furnace.

He held a few kilograms of black gold in his right hand, released a Dan fire and began to melt the black gold. Black gold was only roughly refined by the research institute at that time, and the refining method was very backward and contained many impurities. The black gold gradually melted under the scorching fire in Ma Fan's hand, and the impurities in it gradually disappeared with the bursts of green smoke, and slowly only some black and shiny metal liquid remained. Ma Fan induced the magic trick, and the metal liquid flowed slowly, gradually combining into the shape of a three-legged Dan furnace, about half the size of a basketball, and a long black dragon coiled around the outside of the furnace body, as if soaring for nine days, swallowing the world.

About an hour later, Ma Fan collected the Dan fire, and at the same time slowly poured spiritual energy into the Dan furnace with both hands. Under the nourishment of the aura, the Dan furnace gradually cooled, and a circle of black cold light emanated from its body.

Ma Fan put the Dan furnace on the floor, sealed his hands, and constantly carved the formation patterns on the Dan furnace. Gradually, a little sweat oozed from Ma Fan's forehead.

Although Ma Fan has now entered the Qi refining period, this is the first time that his current body has refined the Dan Furnace, and the aura in his body is barely able to support it.

The formation patterns were fully depicted thirty-six, and it was not until the body of the Dan furnace could no longer bear more formation patterns that Ma Fan stopped his hands. At this time, Ma Fan was panting uncontrollably.

On the floor, a dark Dan furnace with a faint cold light stood quietly. Ma Fan picked up the Dan furnace and nodded with satisfaction. "That's right, Yellow-level Nine Pindan Furnace. It seems that my refining technique has not fallen. "The Dan furnace made of black gold, the highest grade is only the yellow level nine grades. Ma Fan bit the middle finger of his right hand, and a drop of blood fell on the Dan furnace. Then Ma Fan's mind moved, and the Dan furnace shrank suddenly, turning into a pendant the size of a fingernail, like an ornament. Ma Fan took out the keychain, passed through one of the handles of the Dan furnace, and set the Dan furnace.

In fact, Ma Fan has a natal Danding on the Haotian Continent, Ma Fan named it "Tianhong", a heaven-level nine-grade Danding. Tianhong Ding is a very legendary Danding in Haotian Continent, after all, there are only three heaven-level nine-rank Danding in the entire Haotian Continent. It's just that Ma Fan has been hiding the rainbow ding in his body before, and he doesn't know if he survived that accident. Originally, Tianhong Ding had already cultivated the machine spirit, if he survived that accident, not only would he go to the earth with the Mixed Yuan Ring? Ma Fan couldn't help but be full of anticipation.

Originally, Ma Fan planned to continue refining some beauty pills, but found that the medicinal materials had already run out. I had no choice but to go and buy medicinal herbs tomorrow. In addition to the materials for the Yangyan Pill, Ma Fan also prepared the pill "Qi Inducing Pill" required for the refining period. "Qi Induction Pill" is a kind of pill dedicated to the early stage of the Qi refining period, and after taking it, the speed of the spiritual energy will be accelerated by a hundred times. Ma Fan thought about the Dan prescription of the Qi Inducing Pill for a while, fortunately, the medicinal materials required are very common on the earth, and some medicinal materials are simply the most ordinary medicinal materials.

The Haotian Continent is abundant in spiritual energy, and the production of various medicinal materials is abundant. However, the raw materials for an elixir similar to the Qi Inducing Pill do not have high requirements for aura, so the corresponding medicinal materials on the earth should also have similar medicinal effects. Ma Fan took out a piece of paper and wrote down the materials for the Qi Extraction Pill, preparing to purchase them together tomorrow.

Remembering that what he lacked most now was time, Ma Fan decided to resign as soon as possible. For Ma Fan now, this job is no longer necessary.

Ma Fan opened the bedroom door, went to the living room to drink a little water, and found that Long Qian's bedroom was not moving. After sensing it, there was an even breathing sound in the bedroom, and it was estimated that the little nanny had already slept.

Back in the bedroom, Ma Fan continued to cultivate. Breaking through the quenching stage and entering the qi refining period, the body no longer needs much sleep. What Ma Fan needs more now is to seize the time to improve his cultivation.

Soon, the two spars were refined and absorbed by Ma Fan.

"It seems that the Mixed Yuan Ring needs to be brought out as soon as possible now, otherwise it will be too inconvenient. "This hedron will not last long, and soon the hedron will be depleted. If you can bring out the Mixed Yuan Ring, there are still a large number of crystals, magic weapons, weapons and other items of various levels, and even various cutting-edge technological products in the Haotian Continent are also piled up. After all, Ma Fan was the sect master of the Xuantian Sect in the Haotian Continent, and many of the sect's cultivation resources were in his hands. In addition to cultivators, Xuantian Sect also has countless cutting-edge scientists. In the Haotian Continent, cultivation and technology have developed simultaneously, and even the degree of technological development has surpassed cultivation in some aspects, and cultivators below the Yuan Infant Stage can even achieve mass production with the help of scientific and technological equipment, but this kind of mass production cultivators can no longer improve their realm. Therefore, except for some people who are too poor in qualifications who are willing to accept scientific and technological transformation to reach the Yuan Infant Stage, others are almost unwilling, and they are all cultivating to improve the realm by themselves.

At about four o'clock in the morning, Ma Fan finished his cultivation and began to sleep.
