"Why isn't there an introduction to the Hidden True Spirit Pill on the ordinary book?" Feng Fan asked a little impatiently.

"In fact, the Hidden True Spirit Pill is really a chicken rib, and its refining is extremely difficult, and its preciousness is much more difficult than the marrow pill used to build the foundation. After taking this elixir, you can only hide your cultivation for ten days, and it will automatically expire after ten days. The type and preciousness of the spirit grass required to refine the Hidden True Spirit Pill are much higher than those of the Transforming Pill, and the medicinal effect can only last for ten days, so even if many monks obtain the materials for refining the Hidden True Spirit Pill, they will not easily refine it, and they will all use it to refine other precious spirit pills. The Hidden True Elixir is rarely refined, and over time, this elixir becomes more and more rare, and even the books that record this elixir are becoming fewer and fewer. However, the Hidden True Elixir has its magic, and after taking it, the cultivation will hide three levels, for example, after the foundation building mid-stage monk takes it, other monks will use their divine sense to explore, and they will think that the person taking it is the mid-stage cultivation of gathering qi. The opponent has great deceptive power when he does not use a lot of True Element, but if the opponent uses a large amount of True Yuan to attack or defend, his true cultivation will be exposed. Taking two pills can hide six levels of cultivation, for example, a mid-Yuan Infant monk taking two Hidden True Spirit Pills can make others look like they are mid-stage foundation building cultivators. Similarly, taking three pills can hide nine levels of cultivation, and so on, while the effect of the Hidden True Spirit Pill on the contrary is exactly the same as that of the Hidden True Spirit Pill when it falsely raises the cultivation level. The vain real person stared at Feng Fan and explained calmly.

"What will happen if the Qi Gathering Stage Monk takes it?" Feng Fan asked with a dry smile.

"If a Qi Gathering Stage monk takes it, even a Qi Gathering Early Stage Monk can only hide his cultivation as the early Qi Gathering Stage after taking it, and if he meets all the early stage of Qi Gathering and above monks, he will be able to see through the real cultivation, have you ever seen this kind of elixir?"

"The younger generation has never seen this elixir, but only occasionally heard others say it, and they don't know what this elixir looks like. Feng Fan sneered.

"The old man saw it once more than a hundred years ago, and this elixir is yellow in color and has a special smell. The false real man said lightly.

"I see!" Feng Fan nodded happily and said with a light smile.

Figuring out the efficacy of the Hidden True Elixir, Feng Fan returned to his residence, cleaned up, prepared some food, and then left the Flying Sect. More than two hours later, Feng Fan flew into Yimang Mountain.

Feng Fan followed the same path, and a few days later, he came to the place where the old man in Tsing Yi intercepted and killed him. Feng Fan was fully on guard, locking his divine sense onto the black shield while carefully exploring the surroundings with his divine sense.

Suddenly, Feng Fan felt a powerful divine sense coming from far and near. Feng Fan looked into the distance, only to see an old man in Tsing Yi flying towards him from the air in the extreme distance, and the person Feng Fan had already recognized was the monk of the initial level of the middle stage of foundation building who had chased him a month ago.

Feng Fan did not escape, and was determined to give his opponent a free hand and kill him. Feng Fan's right hand flipped, and the Five Elements Xuanmeng Banner appeared in his hand, and as the array flag danced, Feng Fan began to quickly lay out the Five Elements Xuanmeng Array Simple Array.

The old man in Tsing Yi flew a few feet in front of Feng Fan, and seeing that Feng Fan did not escape, there was a puzzled look on his face. Last time, the opponent fled in a hurry, but this time he was waiting for himself, did the opponent ask for help?

The old man in Tsing Yi spread his senses, except for the small black flag in the opponent's hand, there was nothing unusual around, so he said unscrupulously: "Boy, this time you are dead!"

Feng Fan had already finished laying out the simple magic array of the Five Elements Xuanmeng Array, and with a wave of the array flag in his hand, countless cyan ripples surged around the body of the old man in Tsing Yi, and the simple magic array of the Five Elements Xuanmeng Array was urged, trapping the old man in Tsing Yi in the array.

The old man in Tsing Yi suddenly felt that his eyes were hazy, and he lost the trace of his opponent, and he couldn't see everything around him clearly. The old man in black then felt that some of the True Yuan seemed to be banned, and he couldn't help but be shocked, realizing that he had been trapped by the magic circle, so he immediately urged the True Yuan Imperial Cover.

Feng Fan collected the Five Elements Xuanmeng Banner and threw out a few pieces of high-grade crystal jade, and the true element within it was instantly absorbed by the large array, thus maintaining the automatic operation of the Simple Array of the Five Elements Xuanmeng Array.

Feng Fan's mind then moved, and a Qinghong sword flew out from the Five Elements Xuanmeng Ring. Feng Fan pointed at the Qinghong Sword, and the Qinghong Sword quickly flew into the formation with a soft groan.

The old man in Tsing Yi suddenly saw a white light flying in, and with his right hand, he slapped the storage bag on his waist, and the iron ball flew out. After a crisp sound, the iron ball blocked the Qinghong Sword, and the two magic weapons fought fiercely.

Seeing that he couldn't attack for a long time, Feng Fan flipped his right hand, and the Mixed Spirit Devouring Yuan Bead appeared in his hand, injecting a Five Elements Xuanmeng True Yuan into it. Feng Fan's right hand was raised, and the Mixed Spirit Devouring Yuan Bead quickly flew into the big array.

The old man in Tsing Yi was resisting the attack of the Qinghong Sword when he saw a gray bead flying in. The bead stopped outside the True Yuan Imperial Cover around his body, and the old man in Tsing Yi suddenly felt that the True Yuan was pouring out like a flood bursting the embankment, and he was horrified in his heart, and exclaimed, "Gu Bao!" It's just that he didn't know that this was a spiritual treasure from the Immortal Demon Realm.

The old man in Tsing Yi was originally trapped in the simple magic circle of the Five Elements Xuanmeng Array and was forbidden a small part of the true element, and then controlled the iron ball to resist the Qinghong Sword and consumed some true yuan, and at this time, he was quickly absorbed by the Mixed Spirit Devouring Yuan Bead, and his own true yuan consumption was even greater.

The old man in Tsing Yi immediately took out a piece of super-grade crystal jade to replenish the true yuan, but soon the crystal jade became dim, which was a symbol of the exhaustion of the true yuan. The old man in Tsing Yi successively changed countless pieces of crystal jade of various grades, but they were all quickly exhausted.

When the old man in Tsing Yi could no longer take out the crystal jade, his face became extremely ugly. Because the Mixed Spirit Devouring Yuan Bead had absorbed a lot of True Yuan from the monks of the Foundation Building Period, it was a little brighter, and the True Yuan Imperial Shield around the old man in Tsing Yi had almost collapsed.

The old man in Tsing Yi patted the storage bag on his waist, and a talisman appeared in his hand. Feng Fan saw very clearly outside the formation, he didn't give his opponent a chance at all, his right hand flipped over, and a purple Yue golden wheel appeared in his hand.

Feng Fan injected the True Yuan into it, and then raised his right hand, and the Ziyue Golden Wheel flew into the large array. With a muffled sound of "bang", the purple golden wheel was blocked by the true yuan imperial shield of the old man in Tsing Yi, and the cyan light mask produced bursts of violent fluctuations, which had the potential to collapse at any time. The Ziyue Golden Wheel could even break through an ordinary magic circle, not to mention the defensive shield of a mid-foundation foundation beginner-level monk whose True Yuan was about to be exhausted.

Just a stalemate, he broke through the true yuan imperial cover of the old man in Tsing Yi and directly cut off the head of the old man in Tsing Yi. The eyes of the old man in Tsing Yi were still full of unwillingness, and he didn't expect that his cultivation was two levels higher than that of his opponent, and he would die in the hands of his opponent.
