Preparations before No. 189 sets off

  After leaving the room, Qi Feng and his group were arranged to stay in a nearby house. At this moment, it was the most difficult time for him, but gradually he calmed down.

  This trip to the Demon Clan's sacred land is no trivial matter. With the help of the Cloud Clan, it's not difficult to enter, but finding the Medicine King Scripture inside and leaving safely won't be easy either.

  So, during this period of time, he also needs to sort things out and think carefully.

  His greatest reliance now can be said to be the soul dan of that sea beast, followed by Yun Kong. He has comprehended the Qinglian Sword Domain and is also a Dao-level artifact himself.

  Apart from that, it was just him, unfortunately his seventh layer of strength had not yet stabilized and he could not exert the abilities that should have come with the seventh layer. Otherwise, he would have been able to exert the power of the late stage of the combined body and would have had no problem resisting the early stage of the Tribulation Period's demonic cultivators.

  But he needs time, and now time is too scarce for him, he can't afford to waste it on this.

  "Master, this trip to the Demon Clan's sacred land is fraught with danger. I think we need to prepare one more thing before we go." Suddenly, Yun Kong transmitted his voice.

  "What's being prepared?" asked Zhi Feng.

  "Yin Yang Lei Huo Dan!" Yun Kong replied.

  "Yin-yang Thunder Fire Pill? Medicine?" Qi Feng heard this name and immediately thought of the Yin-yang Harmony Powder and Yin-yang Pulse-Stopper Pill that Yun Kong had used before, both of which started with "Yin-yang".

  "Not medicine, but a bomb. The Yin Yang Thunder Fire Dan is a terrifying bomb that requires the use of a demon beast's inner dan to make. The higher the energy contained within the inner dan, the stronger the explosive force will be." Yun Kong explained somewhat awkwardly.

  "You mean... to make the inner elixir of that demon beast into a yin-yang thunder fire pill?" Qi Feng's eyes lit up, that sea beast was a terrifying existence that had lived for tens of thousands of years.

  The energy contained in his body's inner elixir is as terrifying as it can be imagined, absolutely no less than the energy contained in the bodies of cultivators in the late stages of Tribulation or even the Mahayana stage.

  If it is used to make a yin-yang thunder fire pill, the explosion will be equivalent to a self-explosion of a cultivator in the late stage of crossing the calamity or even the Mahayana stage. The power can be imagined.

  It's just that making this inner elixir into a yin-yang thunder fire elixir is somewhat wasteful, after all, this thing is the best material for refining elixirs, and it can definitely create a batch of top-notch masters.

  But he couldn't do anything about it now, his priority was to retrieve the Medicine King's Scripture and save his sister, other things could be discussed later.

  "Not bad, using the inner elixir of that sea beast to make a yīn-yáng thunderfire elixir. Once it explodes, I'm afraid even the great powers of the demon tribe won't be able to face it easily. Some small fries can completely ignore it. With this, plus its soul elixir, and my Qinglian sword domain, leaving safely shouldn't be too difficult." Yun Kong replied.

  "How long will it take for this Yin Yang Lei Huo Dan to be ready?" asked Qi Feng.

  "Ordinarily, a Dan medicine would last half a day, but the internal elixir of this sea beast is many times stronger than an ordinary internal elixir. I estimate it will take at least two days, at most two and a half days, just enough to make it in time." Yun Kong thought for a moment before responding.

  "Alright, I'll leave the Inner Dan to you, you can refine it. These next few days, I'll try my best to consolidate my cultivation. After all, when we go to the Demon Clan's Sacred Land, we won't encounter extremely powerful individuals right from the start. If my strength is a bit greater, the possibility of us leaving safely will also be greater." Qifeng said.

  "Alright." The two of them then divided the work, Yun Kong hid to one side to refine the Yin Yang Thunder Fire Pill, while Qi Feng sat cross-legged, starting to cultivate and consolidate his cultivation.

  In this way, two days passed quickly, and Yun Kong was still making it, but it was already nearing its end, and it would not take long to complete.

  On this day, Zhao Xuan suddenly came over and knocked on Qi Feng's door.

  "How did you get here?" Qi Feng had told her before that he would be in seclusion for a period of time and it was best not to look for him unless absolutely necessary.

  "This trip to the Demon Clan's sacred place is fraught with danger, and my cultivation is limited, so I won't be able to go with you. However, I can lend you a helping hand." Zhao Xuan said as she took out a book, which was the divine tribe's secret method that she had silently written down over the years, and also handed over a blood-colored bead to Qi Feng, "This book contains many powerful secrets of the divine tribe, and this bead contains a large amount of divine blood. Take it with you, and who knows, it might save your life at a critical moment."

  "Shen Zu Secret Method?" Qi Feng was taken aback, and after glancing at the book a few times, he quickly furrowed his brow and said: "The blood in this pearl isn't yours, is it?"

  "It's not mine, even if I were to extract all the divine blood from my body, it wouldn't be that much. This was left behind by a senior member of the Divine Clan, but I've always been reluctant to use it. Since you're going to the Demon Clan's sacred land where danger lurks around every corner, take this with you as a precaution. Alright, I won't disturb your seclusion anymore, I'm leaving." Zhao Xuan said, then waved his hand at Qi Feng and left the place.

  "Thank you." Zhi Feng shouted at Zhao Xuan, he was very clear about the value of this divine blood and the secret method of the divine tribe. The value of a secret method created by gathering the power of an entire tribe can be imagined.

  Especially this divine blood, it is now the only pure-blooded divine blood in the world, once used up, there will be no more.

  Zhao Xuan didn't respond and soon disappeared from Qi Feng's sight, but Qi Feng secretly decided to keep this divine tribe secret method for the last resort, if it wasn't used, that would be best.

  For the next half day, he was studying the divine tribe's secret method.

  The divine tribe's secret method is actually very simple and doesn't require cultivation, just remember the incantation and burn the divine blood to cast it, which has an essential difference from the secret methods of the human and demon tribes.

  So, after half a day's effort, Qifeng had memorized the entire secret manual, and perhaps one of them could help him escape his predicament, so he didn't dare to be careless in the slightest.

  By the afternoon, Yun Kong still hadn't finished making the Yin Yang Lei Huo Dan. He said that the energy within this inner dan was much stronger than he had imagined, so it would take some more time.

  Anyway, there's still half a day and night left, he didn't rush either.

  Later, Yun Die came again, but not to inform Qi Feng of his departure, but to bring him a map of the Demon Clan's sacred land. After all, that place was originally their home, and they were more familiar with it than anyone else.

  This is undoubtedly a timely help. With it, you can save a lot of time and energy, and the possibility of coming out alive is greatly increased.

  "Thank you, Yun Die." Qi Feng thanked.

  "Don't be polite, it's better for you to take a look at this map before you leave. The elders have also left some marks on it, which are the most likely places where the Medicine King Scripture is sealed." Yun Die reminded.

  "Thank you, I'll take a good look." After sending off Yun Die, Qi Feng spent half a day repeatedly examining the map, memorizing every detail before stopping. He then stored the map in his spatial ring.

  At this time, Yun Kong's Yin Yang Lei Huo Dan was also completed.

  When I saw this inner elixir again, it was densely covered with golden runes and radiated a brilliant glow, looking extremely beautiful.

  "Everything is ready, all we need now is a push from the East Wind..."
