Years passed, and in a twinkling of an eye, a year passed in such a hurry.


    A year has gone through a round of four seasons for mortals, but for friars Shen Ruiling, it is just a flick of the finger.


    In this year, almost all bookstores in yunbei City, large and small, received a special customer.


    This special customer looks ordinary, but his origin is mysterious. The key is that he needs something very special.


    He doesn''t need any secret skill books to inherit his skills. He just needs to collect the ancient books that have been dated.


    Moreover, he doesn''t accept ancient books with only two or three hundred years of age, but only those that were written four or five hundred years ago.


    As long as the year of the ancient book meets his requirements, no matter what the contents of the book are about, the customer will buy it without hesitation.


    Taking advantage of this opportunity, some useless ancient books that had been stored for many years in some stores were thrown out by the shopkeepers.


    For a time, all the shopkeepers made a lot of money, and everyone''s face was like happy flowers.


    In this year, Shen Ruiling spent most of his time studying danfang, except occasionally going to Siyi hall to supplement some pills on the shelf.


    What he has to do is to find some clues about "Solanum nigrum" from the ancient books he bought in this volume.


    Then, based on their own knowledge of the elixir reserve, we can infer what kind of elixir the "Solanum nigrum" has in the immortal world.


    After finding this elixir, if Shen Ruiling doesn''t have it, he has to go to the square city to search for it.


    Finally, after he spent a lot of energy to get this elixir, he must carry out the final step of alchemy verification.


    However, when he finally completed the previous steps, the last step often ended in failure.


    Over the past year, there has been a sound of furnace explosion in Shen Ruiling''s underground fire room from time to time, and each sound of furnace explosion declared the failure of his experiment.


    However, although these alchemy experiments have not been successful once, they are not necessarily fruitless for Shen Ruiling


    Through frequent and intensive alchemy in this year, Shen Ruiling''s spiritual power has been fully polished.


    The problem of spiritual vanity caused by taking snake saliva fruit has been completely solved.


    At this time, although Shen Ruiling still stayed at the top of the fourth floor of the foundation, his spiritual power was much stronger than when he just broke through.


    Shen Ruiling couldn''t help guessing in his heart. According to his current situation, he can break through again in a year and a half!


    Every time he thought of this, Shen Ruiling couldn''t help laughing.


    Of course, this is not the happiest thing for Shen Ruiling.


    For Shen Ruiling, the happiest thing now is to suddenly find that his cultivation speed has accelerated a lot.


    Since Shen Ruiling''s cultivation has broken through to the fourth floor of the foundation, he began to practice this part of the skill about the middle stage of the foundation in the [Sanyuan zhuanlei Jue].


    In the early stage of foundation construction, Shen Ruiling majored in fire power, while earth power and water power were just a simple minor.


    However, when his cultivation broke through to the middle of foundation construction, the focus of Kung Fu began to change.


    From the original fire system, supplemented by earth system water system, to earth system, supplemented by the spiritual power of water and fire system.


    After a year of cultivation, Shen Ruiling found that the fire spirit root and Earth Spirit root in his body had begun to blend.


    Even his own spiritual power of these two attributes began to become more and more compatible, resulting in his cultivation speed much faster than at the beginning of foundation construction.


    If he could only refine a wisp of spiritual power into his body in one incense stick, now he can at least refine half a wisp more.


    Although half a wisp of spiritual power is insignificant alone, when countless half wisps of spiritual power come together, it is an unimaginable majestic spiritual power.


    Originally, after Shen Ruiling practiced the [three yuan to thunder formula], his cultivation speed was almost equal to that of ordinary monks with double spirit root qualification.


    Now, due to the blending of earth and fire spiritual roots, his speed of refining spiritual power has been improved again, which has faintly exceeded the general double spiritual root friars.


    After discovering this phenomenon, Shen Ruiling''s face immediately showed a look of shock. In his heart, he couldn''t believe that all this was true and thought it was just his own illusion.


    But after he did take office again and again, Shen Ruiling affirmed that all this really happened in his body!


    For a moment, Shen Ruiling did not mention how excited he was. Tears of excitement poured out of his eyes.


    The acceleration of cultivation speed will be an essential change for friars, which means that he can go further in the future.


    After a short shock, Shen Ruiling began to think seriously.


    He can be sure that all these changes are caused by practicing the skill [Sanyuan zhuanlei Jue].


    I think when he chose to practice this skill, he was skeptical and ready to take a step by step. He didn''t have much confidence in the change of Linggen in the last step.


    But now it''s different. All kinds of signs show that the possibility of spiritual root fusion exists.


    Therefore, after understanding these, Shen Ruiling''s heart was immediately excited, and at the same time, a belief of courage also rose quietly in his heart.


    Now that he knows that the [three yuan to thunder formula] is likely to succeed, he must try it and fight a bright road for himself in the future!


    ……


    This day, in the dark underground fire room, Shen Ruiling started his alchemy experiment again.


    The miraculous medicine he chose this time is only a second-class spiritual plant, but it is also extremely rare.


    Shen Ruiling went all over yunbei city and didn''t find it. Finally, he traded it from the Song family by relying on Shen Ruiling''s relationship.


    With the input of miraculous drugs, Shen Ruiling''s face began to look forward to it as before.


    Although the past year has been a failure, Shen Ruiling has not given up. It is still hard for him to study this danfang again.


    With the passage of time, Shen Ruiling''s eyes gradually began to flash a look of joy.


    This alchemy actually continued to the link of alchemy. You know, so many previous experiments have failed in the impurity removal stage.


    After feeling the violent vibration of the pill oven and realizing that the pill in the oven was slowly taking shape, Shen Ruiling couldn''t help but get nervous.


    In the anxious waiting, time passed imperceptibly.


    With a little muffled noise, the alchemy was finally over.


    There was no black smoke after this alchemy, which obviously means that this pill has been successfully refined.


    According to the excited mood, Shen Ruiling directly lifted the stove cover and held a purple elixir in his hand.


    After a moment of hesitation, Shen Ruiling scraped some powder from the pill, treated it with the alchemist''s special technique, and then slowly put it into his mouth.


    As the efficacy of those powders began to attack gradually, the happy color on Shen Ruiling''s face became more and more rich.


    Although he doesn''t know whether he has restored the complete elixir, at least now the effect of this elixir is still good.


    When Shen Ruiling was ready to try the efficacy of this elixir again, the ground fire chamber where he was located suddenly began to shake violently.


    Even the sealed ground fire began to become irritable, as if to break through the seal.


    "What happened?"


    Shen Ruiling was shocked.
