Seven days have passed, and according to Su Hongrui's calculations, Yuhu should have risen to level forty-eight, but it still stayed at level forty-seven.

It stands to reason that the pills given by Su Hongrui are enough for it to rise to two levels, but now the first level has not been upgraded, there is only one possibility, it gave all the pills to Feng Ling, the child of the Feather Tiger Demon God!

It's a licking tiger! Su Hongrui felt that he had found the wrong target, he should find Feng Ling first, so that he could pick up a feathered tiger licking dog for nothing, and the current situation is that Feng Ling prostituted Su Hongrui's seven-day experience pill, and Su Hongrui may have no money at that time.

However, now Su Hongrui wants to focus on the eighth-order experience pill, which is related to whether he can obtain a god-level demon dragon, Su Hongrui prefers dragons to tigers! Because the dragon looks a little more domineering.

"You go outside and guard first!" For the sake of insurance, Su Hongrui asked Yuhu to go outside to guard first, and in the past seven days, Su Hongrui was busy refining the sixth-order experience pill, which was an important currency of the demon clan, so he gave priority to refining the sixth-order experience pill.

As for the seventh-order elixir, Su Hongrui was ready to skip it directly, because Su Hongrui felt that the key to refining the elixir had nothing to do with himself, mainly to see if the "Fire" could be burned, if he could, he could refine the eighth-order experience pill, if not, then Su Hongrui would choose to use these sixth-order experience pills to get out for himself, Su Hongrui was the Hundred Demon Burial Master, so he believed that the Feather Tiger Demon God would let Su Hongrui go for the sake of the face of the War Demon King, and would not really let him refine the elixir for a lifetime in Fengyunling.

The higher the level of the medicinal materials, the longer it takes Su Hongrui to refine the medicinal materials, and the longer the time, the more "Fire" will be consumed, and the "Fire" consumed by refining a sixth-order experience pill is the amount consumed by fighting two life-and-death battles.

Now the difficulty has been directly upgraded from the sixth order to the eighth order, Su Hongrui himself actually doesn't have much confidence, the Iron Guard Demon God has been sent back to the Hundred Demon Burial Ground by Su Hongrui, because in the face of the upper gods, the Iron Guard Demon God and Su Hongrui are both experience-giving, and they don't play a big role at all, and it's not a good thing to be monitored all day long, so it's better to let it go back.

After Su Hongrui activated the "Fire" in his hand, the originally dark room instantly lit up, and these medicinal materials all rose into the air with the flames, using the entire stone house as the furnace and Su Hongrui as the fire! Began refining the Eighth-Order Experience Pill.

The Feathered Tiger Demon God stood on a peak opposite Su Hongrui and observed very carefully, judging from its experience in the past seven days, Su Hongrui should have started refining the pill again!

In terms of refining medicine, Su Hongrui was able to achieve such an achievement before the age of thirty, and the Feather Tiger Demon God felt that it was inseparable from the flame in Su Hongrui's body.

In the past few days, the Feather Tiger Demon God has discovered a small detail, that is, the stone house where Su Hongrui lives is getting brighter and brighter, and the grade has actually become higher! From the original fourth-order Fengyun Stone to a fifth-order Fengyun Stone.

It's a pity that the Feather Tiger Demon God doesn't rely too much on equipment, otherwise you can consider letting Su Hongrui burn it with his flame and refine the equipment.

"Father, he's starting to refine the elixir again!" Feng Ling has tasted the sweetness of the pill in the past few days, and every time he arrives at this time, Yuhu will be guarding at the door, which means that Su Hongrui is going to start refining the pill, and every morning Yuhu will bring two or three experience pills to his own territory, and then it can enjoy the experience pill happily.

The Feather Tiger Demon God looked at his daughter very helplessly, just like this, he will manage Fengyunling in the future? In the future, it is better to let it have less contact with clouds......

It stands to reason that the Feather Tiger Demon God should not care about Feng Ling, because it is the responsibility of the female tiger to take the cubs, but Feng Ling's mother and the mother of the Feather Tiger are dead, so the Feather Tiger Demon God can only take on the responsibility of taking the cubs.

Su Hongrui in the small stone house was burned by endless flames, if it was a normal alchemist, he would have been burned to death by the flames, but Su Hongrui was not a normal alchemist, according to the plan of Blood Yaoyi, Su Hongrui would eventually become the spirit of "Fire", that is, the fire spirit.

Therefore, Su Hongrui, who was surrounded by flames, did not have anything to do, but felt very comfortable, and the medicinal materials became liquid, refined and fused in an orderly manner, and according to the different medicinal materials, the proportion of each medicinal material fusion was also different.

Su Hongrui would be amazed every time he watched the alchemy of "Fire", these flames were like having spiritual intelligence, who would have thought that the key point of this alchemy was the flame instead of the alchemist.

Time passed bit by bit, and Su Hongrui felt that this time the alchemist was even longer than before, and the medicinal materials had only been refined so far, and there were still more than sixty kinds of main medicines and more than eighty kinds of secondary medicinal materials that had not been refined.

Su Hongrui felt that he still underestimated the time it took to refine medicinal materials, which may have something to do with the level of "Fire", Su Hongrui felt that the speed of refining medicinal materials this time had slowed down significantly, and the refining was very reluctant.

Since quality is not good, then win by quantity! The flame that Su Hongrui put in before could only barely refine the three beads of medicinal materials, but now Su Hongrui invested three times the amount of the previous "Fire", so the "Fire" can now refine the nine beads of medicinal materials at the same time.

After the medicinal materials are refined, there is a time limit for fusion, and some of them must be fused with another bead of medicinal materials immediately after they are refined, otherwise other medicinal properties will be fused, or the medicinal power cannot be maximized.

These are all things that Su Hongrui knows after reading the "Pharmacopoeia" for more than 20 days, the speed of refining medicine was visible to the naked eye in the past, but now it is too slow, so Su Hongrui must find a way to improve the speed and make the medicinal materials perfectly integrated, otherwise it is okay to refine the pill of low quality, at least it is refined, I am afraid that the refining will fail.

There is not much time left now, it will be two days after today, and it is impossible to restore "Fire" to half in two days, so Su Hongrui's alchemy must succeed this time!

Time is passing faster and faster, and Su Hongrui's "Fire" is getting less and less, and Su Hongrui feels that if he can't refine it within three hours, he can only give up.

Because some medicinal materials have already been fused together, if the fusion is not continued, the refined medicinal materials may lose their original medicinal power.

The higher the grade of the elixir, the faster the refining of the medicinal materials, and the fusion of the medicinal materials before the expiration date, of course, not all medicinal properties are burned with fire.

The water demon vine of the water attribute cannot be burned directly with flames, according to the normal process of refining medicine, it should be slowly boiled with warm water for eighty hours, and then the medicinal properties can be activated.

But Su Hongrui only had flames now, and it was impossible for him to wait for eighty hours for the water demon vines.

According to the planned time, there should be an hour left, Su Hongrui took a deep breath, but unfortunately there was only carbon dioxide and high-temperature flames around, and Su Hongrui took a lot of flames in these two mouthfuls.

The remaining time is definitely not enough, there are still more than seventy kinds of miscellaneous medicinal materials that have not been refined, and the remaining time is definitely not enough.

What Su Hongrui didn't expect was that the difficulty of refining eighth-order medicinal materials was so great, the difficulty of refining a pearl of eighth-order medicinal materials and refining a fifth-order experience pill, Su Hongrui felt that he was a little overwhelmed......

"Are you going to fail?" Su Hongrui felt a little out of breath, his consciousness began to blur, and he might not be able to refine all these medicinal materials.

When Su Hongrui estimated that there was still half an hour left, Su Hongrui was physically exhausted and fell directly to the ground, and the medicinal herbs circling in the upper mouth did not begin to slowly decline.
