The three of them walked in the cracked tunnel for a long time, and suddenly Yang Laoyu stopped.

"Sister Yang, what's wrong?" Qin Xuan was a little puzzled.

"Brother Qin, I don't know if you've ever heard of Yin Yuan Lotus?" Old Lady Yang looked at Qin Xuan.

Qin Xuan frowned slightly, although he had read a lot of books, there were no wonders in the world, and he had really never heard of this Yin Yuan Lotus.

"What does Sister Yang mean by asking?"

"Because there's a Yin Yuan Lotus hidden here!"

Old Lady Yang walked to the side of the tunnel, where there was a dark pool.

There is an eerie aura emanating from the waterhole, which makes people feel intimidating.

"Seventh Sister Qing, borrow your long whip. Mrs. Yang said.

"Sister Yang, take it!" Qing Qiniang handed the long whip to the old woman.

I saw that Yang Laoyu threw out a long whip, rolled it gently, and pulled the Yin Yuan lotus root up, and then she wrapped it in cotton cloth.

Qin Xuan and Qing Qi Niang curiously walked to Old Concubine Yang to watch.

This Yin Yuan Root is the same size as an ordinary lotus root, but it is pitch black all over, and it also exudes a strong cold atmosphere, so you can know that there is a problem at a glance.

"The two of you don't know that Yin Yuan Lotus is a medicine specially used to increase longevity, which can increase the lifespan of martial artists below the sixth order by nearly ten years, but unfortunately, the side effects of this medicine are too great, and it is only suitable for the secret method of refining corpses of the Wu clan. ”

"Ten years old, Sister Yang, what you said is true or false, this black lotus root is actually a longevity elixir?" Qing Qiniang said in shock.

Qin Xuan was also moved.

The elixir that increases longevity is extremely rare, more precious than the thousand-year-old elixir, he has seen the introduction of this kind of elixir in many books, but each of those elixirs is famous, and there is no Yin Yuan Lotus among them!

"The old body said, this medicine has great side effects and is not suitable for taking, so listen to me slowly. The old woman said leisurely.

"Eldest Sister Yang, no matter how big the side effects are, it is also a longevity elixir, isn't Eldest Sister afraid that I will rob it?" Qin Xuan asked in a deep voice.

This is an elixir that increases longevity!

With an extra ten years of life, maybe a sixth-order martial artist can step into the seventh-order and transcend mortals, then the longevity can reach two hundred years, and a family will have a pillar to continue!

This kind of longevity elixir is the most precious treasure in the world, and Old Lady Yang actually collected the medicine in front of Qin Xuan, so she couldn't believe in Qin Xuan too much, right?

"Brother Qin should know that heaven and earth are conserved, and everything has its own rules. Most of the miracle medicines that can increase longevity have great side effects. ”

"For example, the five-colored Qionghua, it is said that this magic medicine can increase the life span of mortals for seventy or eighty years, even if it exists above the seventh order, it has a certain effect, and it can be said to be the top treasure in the longevity elixir. However, this medicine will make the user's whole body stiff and unable to move for an hour every day, even if it is a strong person above the seventh order. ”

"Then what are the side effects of this Yin Yuan Lotus plant?" Qin Xuan asked.

"This Yin Yuan Lotus has two major shortcomings, first, the Yin Yuan Lotus is not a miracle medicine, but a ghost medicine, so it is not suitable for human beings, anyone who comes into contact with this medicine will continue to weaken the yang energy, and the true qi cultivation will continue to regress until it becomes a waste person;"

"The second is that this medicine is born with too heavy yin qi, which will make the user gradually become not like a human being, a ghost is not like a ghost, and corpse spots will gradually grow on the body, until the longevity is exhausted, it will become an unconscious zombie. ”

"If you don't believe it, I carry a secret book of insect methods, which clearly records many secret methods of the Wu clan, including an introduction to the Yin Yuan Lotus. Old Lady Yang took out a secret book of insect methods from her waist.

Qin Xuan and Qing Qi Niang stepped forward, and sure enough, there was a page on the secret book that clearly recorded the Yin Yuan Lotus, and the pattern on it was exactly the same as the Lotus Root just now.

"That's why the old body said that this thing is only suitable for the witch clan's secret method of refining corpses. ”
