In the back mountain cave, Shen Ruiling sat quietly on the Pu mat in the cultivation room, his eyes closed, like a motionless statue.


    In his hand, he held a jade slip with aura. His divine consciousness had completely penetrated into it and carefully browsed the contents recorded in the jade slip.


    This jade slip is the one the old medicine gave him a few days ago.


    At this time, Shen Ruiling was completely immersed in the jade slips, and the contents recorded in the jade slips seemed to open a door to the new world for him.


    The contents recorded in this jade slip include the names and properties of many miraculous medicines, various Dan prescriptions, and many other alchemy knowledge that Shen Ruiling has never been exposed to.


    These things constitute a brand-new alchemy system, which is very different from the alchemy system widely spread in the fairy cultivation world in Lingnan.


    Although the two are the same on the basic issue of alchemy, they are the essence of heaven and earth, and they can refine all kinds of Dan medicine that can be easily used by monks.


    However, the alchemy techniques involved in this are different from Dan Fang and pharmacology. In other words, the former is better than the alchemy system Shen Ruiling learned from childhood, and makes more rational use of the heaven and earth elixir in today''s immortal world.


    Due to the closed environment, the cultivation level of Lingnan immortal cultivation community can be said to be very backward. Not only are there few kinds of skills and secrets, but also the inheritance of immortal cultivation skills such as alchemy, weapon refining, talisman making and array is very low. It can be said that there are few people who can reach the fourth level.


    Even the existing skills and inheritance in Lingnan fairy world were brought in from the outside by the ancestors of that year.


    Now, as the Lingnan immortal cultivation world has been closed for a longer and longer time, all kinds of inheritance and skills left by our ancestors are beginning to seem incompatible with today''s immortal cultivation world.


    Although the monks living in Lingnan immortal world have been trying to improve these skills and various inheritance, they are always following the oldest copy.


    Therefore, there is a great difference between the Xiuzhen civilization in Lingnan immortal cultivation world and the external civilization, which is far behind the Xiuzhen civilization that keeps pace with the times.


    I don''t know how long it took Shen Ruiling''s divine knowledge to slowly withdraw from the jade slips. He couldn''t help feeling when he looked at the jade slips in his hands.


    "Is this the inheritance of alchemy outside the immortal cultivation world in Lingnan?"


    He has never heard of the alchemy knowledge recorded in this jade slip. Obviously, it is not the product of Lingnan immortal cultivation world, so it must be the product outside Lingnan immortal cultivation world.


    The impact of this new alchemy inheritance on him can be said to be very huge, which made him deeply see the backwardness and conservatism of Lingnan immortal cultivation world.


    But at the same time, it also opened the door to a new world for him, allowing him to contact the alchemy inheritance of the outside world, so that he can begin to make up for his lack in recent years.


    In the inheritance of alchemy, many external Dan prescriptions are recorded, some of which have similar effects to those in the current Lingnan immortal cultivation world, but the Dan prescriptions used are different.


    Moreover, some of the miraculous drugs used in these Dan prescriptions have appeared in Lingnan immortal cultivation world, but their names have changed dramatically.


    What shocked Shen Ruiling most was the pill similar to the foundation building pill, which was also used to help the friars in the Qi training period refine the violent spiritual power during foundation building.


    However, the main medicine of this pill is not "jiuzhuan Jinzhi", but a few drops of the pill liquid of the fourth order demon king demon pill, supplemented by several third-order middle-class and top-grade elixirs.


    Shen Ruiling, who used the demon pill as a medicine, was still alive. As for why the protagonist took the seed to the medicine, he always looked at it. First of all, he didn''t know the value of the seed and never paid attention to it. He just took it as an unknown pill.


    Secondly, Yao Lao taught him the methods and skills of alchemy before, which can be regarded as pulling in the distance and letting the protagonist put down his defensive heart.


    Moreover, this seed is not the chance of the Shen family. It is prepared for Li ningshang. It can be regarded as the love token of the protagonist. It''s also to make yaolao owe a favor.


    Finally, the Shen family had too many things to do, and there was no way.
