The cave is hot, and the danxiang is fragrant.

Mu Zifeng's retreat took twenty days, and in these twenty days, he almost turned all the elixirs and spiritual herbs on his body into a furnace of elixir, and the Wind Ascension Pill alone was refined by him as many as hundreds, if anyone knows, his storage bag actually contains enough elixir that can turn hundreds of ninth-order great magicians into demon king-level powerhouses, I don't know if the eyeballs will fall to the ground?

Some of the super-grade pills that made the powerhouses of the Demon Venerable rank also very blushing, and he had also refined hundreds of them, some of which were used to heal injuries, some to treat dark diseases, some to assist in cultivation, some to improve one's cultivation, and some to improve one's spiritual power...... There are many of them, all of which are five-pattern gold pills. Individually, there are six patterns, too.

But there is one thing that also makes him feel a strong sense of crisis, that is, after so many uses, the quality of the furnace can no longer meet his requirements, that is to say, he wants to refine the second-grade super elixir, which is no longer enough from the furnace, if it is forcibly refined, I am afraid that there is still a danger that the furnace will destroy the pill.

"It seems that we have to find some refining materials to improve the quality of the furnace and the level of the magic treasure. Mu Zifeng touched the back of his head, and he also felt a headache.

With the improvement of his spiritual power, he will definitely have to refine more super-grade elixirs, and as a high-grade magic treasure, the furnace is barely enough if it is raised to a high-grade magic treasure. To improve the quality of the furnace, the refining materials needed are not what he can have now, or what he can find, so he can only find them slowly in the future.

He shook his head, discarding all kinds of unrealistic ideas, and could only take one step at a time.

On this morning, the sun was rising and shining.

Although there is still a faint coldness in the air, there is also a trace of warmth, winter is about to pass, and a new spring is coming.

And today, it was Mu Zifeng who made an appointment to increase the longevity of the old monster behind Wangelong, who had lived for 2,800 years, as early as when he was refining the pill, he had already set this time through sound transmission.

After all, that old monster's days are running out, and one more day of delay will be more difficult for increasing his longevity.

Mu Zifeng didn't dare to guarantee that the longevity grass would be able to extend his lifespan, according to the information he got from Vasya, the Blue Star people generally had to take the longevity grass when they were born, so that they could effectively improve the physique of the body in order to achieve the purpose of living for 10,000 years, and this longevity grass had never been used on the monks of the demon world, and even Vaxia didn't know what the specific effect was.

Therefore, in the process of refining the elixir, Mu Zifeng also gritted his teeth, used a longevity grass, and according to the secret recipe of the elixir recorded in his mind, supplemented by other herbs, he also practiced seven longevity pills.

The longevity pill was green all over, and after it was baked, Mu Feng felt that his entire cave mansion was full of vitality and vitality as if spring had come.

He secretly thought in his heart, with these seven longevity pills, he could at least extend the life of that old monster by 5,000 years.

The longevity pills he refined were all five-pattern golden pills, and he was going to give one to the old monster first, and if there was an effect, let him take another one every once in a while, so that he could extend the life of the old monster indefinitely.

If he is allowed to take it all at once, if there is no effect, wouldn't it be a tyrannical thing?

Mu Zifeng waved his hand, and the triple formation all retreated, and as soon as he rose and fell, he disappeared into the morning glow, and when he reappeared, he had already arrived at the residence of Wangelong on the first floor.

Wan Gelong was still sitting in front of the coffee table, holding the teacup in his hand, although his face was full of waves, and he could see the apprehension and excitement in his heart from his slightly trembling hands.

Today is destined to be a special day, either a success or a failure.

If it succeeds, it will not only be able to keep his position as the Pavilion Master of the Holy Yao Guang Mountain, but it may also be able to enter the high-level of the Holy Sect's inner gate because of his outstanding performance; if he fails, he will not only not be able to keep his current position, but may also leave a laughing stock and become the talk of the high-level of the Holy Sect's inner gate after dinner.

All the hope is pinned on the body of that Terran monk Mu Zifeng?

Wan Gelong didn't sleep all night last night, and he had no intention of cultivating, he was like a donkey on a mill road, constantly circling around the cramped and cramped dwelling, and there were always a lot of unrealistic ideas in his head, and he suffered from gains and losses.

There were even a few times when he secretly released his spiritual power and secretly spied on Mu Zifeng's cave, but because the defensive formation arranged by Mu Zifeng was very powerful, his spiritual power could not penetrate at all, and he could only give up in the end.

Now that he saw Mu Zifeng coming with his hands behind his back and dragging him with a confident look, his hanging heart was also slightly lowered.

"Mu Xiaoyou, are you ready?" Wan Gelong pretended to pour a cup of tea for Mu Zifeng casually and spoke indifferently.

Mu Zifeng didn't speak, just nodded slightly, and was not polite, took the teacup handed over by Wangelong, took a sip gently, and sat opposite him with a golden knife.

"When is that old-timer that the pavilion master said coming?" Mu Zifeng put down the teaglass, "The pavilion master had better tell him to hurry up, I'm in a hurry!"

With a "poof", Wangelong almost squirted out the hot tea he had just drunk in his mouth, "I'm the pavilion master, okay? He complained in his heart, but because of his identity, he didn't say anything, but from the white eyes of his seven-colored demon pupils, everything was silent.

Mu Zifeng didn't pay attention to Wangelong's performance, turned his head, and suddenly looked at Wangelong's residence to see if he could find some good things, and let him go by the way.

A deep sense of helplessness swelled up in Wangelong's heart, "I'm about to go bankrupt, okay? Even the 50,000 high-grade magic crystals you want, I still managed to get them together, if you want to take anything more, then I still have to sell blood?"

But all this is what he thinks in his heart, as the supreme ruler of Shengyao Guang Mountain, he still has the minimum cultivation and city government, all this can only be thought about in his heart, and he did not express it.

Fortunately, Mu Zifeng looked around and didn't find anything that could enter his eyes, so he retracted his gaze with infinite regret.

Wangeron also breathed a long sigh of relief.

But before it could relax its mood, Mu Zifeng's words almost didn't scare him out of the teacup in his hand.

I saw Mu Zifeng smile slightly, "Lord Wange, do you have Xingchen Essence Iron here?"

"Star Iron?" Wangelong's heart moved, "How could Mu Xiaoyou think of asking for such a thing?"

Xingchen Essence Iron is a good thing, it is extracted from the Star Stone, and it is good that thousands of tons of Star Stone can refine one or two Star Essence Iron, which shows the preciousness of Xingchen Essence Iron, it is the best refining material in the entire Xuan Demon Continent.

And the star stones are all from the interstellar world, just like meteorites on the earth, very rare. One or two stars of fine iron, if it is brought to the auction, it is the existence of the finale, and it can be auctioned at a sky-high price.

In the early years, by chance, Wan Gelong got five taels of star essence iron, and he was as precious as his eyes, and now when he heard Mu Zifeng suddenly mention it, how could he not make his heart tremble?

"Could it be that the news that he is pregnant with the Star Essence Iron has leaked? was remembered by this little ancestor?" A hint of surprise flashed in Wangelong's eyes, and his mind was full of thoughts, "If Mu Zifeng opens his mouth to ask for the Star Essence Iron, how should he deal with it?"

"The juniors are just talking casually, and the Lord of the Ten Thousand Pavilion doesn't have to worry about it. Mu Zifeng picked up the teacup and took a sip gently, "But if the Lord of the Ten Thousand Pavilion knows who has the Star Essence Iron, the junior is willing to exchange it for the Super Grade Pill?"

"Super Grade Pill?" Wan Gelong's shock was no less than the shock caused by Mu Zifeng's request for Xingchen Essence Iron just now.

"After a while, the Lord of the Ten Thousand Pavilion will naturally know!" Mu Zifeng smiled indifferently.

How could he not see the expression on Wangeron's face? This old fellow must have Star Essence Iron, and if he didn't take out something real, something that tickled his heart, he wouldn't obediently give it to himself.

And that star iron is one of the best materials to upgrade from the furnace.

"When will the old man he said arrive?" Mu Zifeng put the teacup on the coffee table and frowned.

"Mu Xiaoyou, don't be impatient, you should already be on the way. Wangron said with a sneer.

Without waiting for Mu Zifeng to continue urging, a coercion far superior to that of Wangelong came from the sky, and the coercion was like substance, even the current Mu Zifeng felt a palpitation, as if a big stone had been pressed in his heart.

"It's here!" Wan Gelong glanced at Mu Zifeng, hurriedly stood up, and walked quickly outside the house.

Mu Zifeng used the immortal power of his whole body and ran for a great week, and only then did he resist the strong coercion, followed behind Wangelong, and also walked out of the house.

The sky darkened steeply, and the sunlight cast the shadows of the three people on the ground, and the shadows were stretched out to grow elders.

Mu Zifeng looked up, but he couldn't see the appearance of the person who came, only to see three black shadows wrapped in black robes, at first they were three small dots, and they looked like they were still ten miles away, but in a breath, the three small black dots turned into three huge figures, appearing in front of him and Wangelong.

The three black shadows were like a layer of mist wrapped outside, the shadows were sufficient, and they couldn't see their appearance clearly, Mu Zifeng ran the Immortal Sutra and the Human Emperor Technique, but he still couldn't penetrate the layer of mist, and he could only feel that the black shadow in the middle was slightly thinner than the one on both sides, just like a bone shelf, and his cultivation was the peak of the second-order Demon Venerable.

And the people on both sides are all at the peak of the First Order Demon Venerable.
