At the same time, Qin Feng finally found a peak lingzun who was willing to try to cross Lei Xiandan. His name was fan Luohong. He came from Tianheng Lingdao and was born with wood spirit. He was nearly 5000 years old.


    Lingzun can generally live about 6000 years old, but if he is over 5000 years old and fails to become an immortal, his Qi and blood begin to weaken and his strength begins to decline, he is doomed to become an immortal.


    It has been nearly two thousand years since fan Luohong reached the peak of lingzun, but it is extremely difficult to think further. The accumulation of such a long period of time only makes him have a 10.5% grasp of crossing thunder.


    But he was not willing to be trapped here. He had planned to try to survive the immortal robbery when he was about to be 5000 years old.


    Qin Feng is a man of the year in the spirit world. When such a strong man finds fan Luohong and tells him that he has a magic pill to help him through the thunder, he is naturally willing to gamble.


    It''s natural to choose a place with rich aura to go through the robbery. Holy Spirit spring city is a good choice. Fan Luohong will go through the robbery here.


    Qin Feng summoned Yang Yuhao to come to Holy Spirit spring city to witness fan Luohong''s rescue, so as to verify the effectiveness of the elixir. At the same time, he gave him the newly collected natural materials and treasures.


    Half a month later, fan Luohong attracted thunder robbers in Chuncheng. When the thunder robbers came, he took the elixir of crossing thunder.


    There was a flash of thunder and lightning all over his body, but the efficacy of Du Lei Xiandan began to play. This thunder and lightning can offset some thunder disaster, and make him have a certain resistance to thunder.


    The thunder disaster lasted for half an hour. Fan Luohong was able to resist the thunder at the beginning. However, after half of the thunder disaster, which was also the most violent, he was unable to resist it and was struck by thunder several times.


    The means of robbery accumulated in two thousand years were destroyed in an instant. Fortunately, lightning flashed on his body, which protected him in the critical moment, counteracted the power of thunder robbery, and failed to kill him.


    In the end, he barely survived the thunderstorm at the cost of serious injury.


    If there is no Du Lei Xiandan, I''m afraid he has turned into ashes.


    Fan Luohong was so excited that he came to Qin Feng and Yang Yuhao to worship each other deeply. He was willing to join Chuncheng and become a free thug for five thousand years. He was more willing to serve Yang Yuhao.


    Qin Feng nodded and asked him to digest the immortal Qi, heal the injury and stabilize the realm.


    After waiting for it to leave, Qin Feng looked at Yang Yuhao and asked, "how about it?"


    "The effect is similar to what I calculated, or even better. It can increase the success rate of robbery by about 20.5%. These days, I''m trying to deduce prescriptions and refining methods. Maybe I can improve them and enhance their effects, barely reaching 30% Yang Yuhao said.


    After hearing this, Qin Feng is delighted to increase the success rate of Du Lei by 30%, which is a great temptation for any cultivator. Du Lei Xian Dan will become a popular product for senior cultivators in the spiritual world. Unfortunately, it''s very difficult to find the natural materials and local treasures needed for refining and mass production.


    With Du Lei Xiandan, Wang Luyao and Wu Wenshuang are expected to become immortals.


    Yang Yuhao stayed in Chuncheng for the time being. He had a new collection of natural materials and local treasures, which was enough to refine them again. He used it to study the prescriptions and refining methods and improve them.


    Qin Feng began to practice in seclusion.


    After all, fan Luohong''s thunder robbery did not cover up at all. He was soon discovered by the good people and then spread.


    In the high-level spiritual cultivation of the spirit world, he soon learned that there was a elixir to help him survive the thunder disaster. The high-level lingzun and even Lingxian couldn''t help but look at Chuncheng, and they were very excited about the elixir.


    But there is Qin Feng sitting in the town, no one dares to make a mistake, even the poor family has been afraid of Qin Feng and the spring family, dare not provoke at will.
