The alchemy information is okay, Zhou Tong plans to study the cultivation pill and the bottleneck breaking pill of the five elements and special attribute spirit cores deduced by the senior monks, and then deduce the three pills that are suitable for the two of them with the Yin Yang Ghost Dragon Spirit Core, the Star Silver Armor Beast Spirit Core and the Golden Flame Spirit Ape Spirit Core as the main raw materials.

As for the witchcraft technique, the reason why Zhou Tong insisted on buying it and letting Fang Huairan study it was because Zhou Tong took a fancy to the two spells in it, the Void Curse and the Void Kill, because they both had certain spatial attributes, and Zhou Tong was also brainy, planning to use this technique to teleport the elixir to Cheng Yao.

Of course, this weird, face-to-face technique is not only quite restrictive to perform, but also quite restrictive to practice.

For example, when casting it, you need the essence blood of the recipient! it is essence blood instead of blood! When fighting enemies, blood is easier to obtain, but essence blood, it is very difficult!

At least Fang Huairan and Zhou Tong have experienced so many battles and have never obtained the enemy's essence blood. When the essence blood can be obtained, the enemy is estimated to be motionless or dead, and then the two have the opportunity to extract the essence blood.

According to the description on the jade slip of the witch Gu technique, the stronger the strength of the recipient, the more the caster will pay, from mana to essence blood to longevity, in short, the more precious it is.

In addition to these two points, in terms of cultivation, a special physique is also required, according to the speculation between the lines of the secret art, this witchcraft requires a special physique to be practiced by a clan, and people from other clans cannot be refined at all.

Of course, there are so many restrictions, and the power of this technique is also extremely strange and domineering, even if the recipient is far away from the ends of the world, as long as the caster has essence blood in hand, has the ability and willingness to pay a sufficient price, can also severely damage or even kill the recipient.

What inspired Zhou Tong's brain was one of the techniques that could teleport the spell to the recipient at a fixed point in the air, and then kill it with one hit.

What Zhou Tong thought was that Fang Huairan was good at teleportation arrays, and the three of them still had each other's essence and blood, so they could improve this technique, only use the spatial teleportation ability in it, and then cooperate with the teleportation array or the Four Spirits Bright Altar to teleport the elixir to Cheng Yao.

After all, Cheng Yao is not in the territory of the two demon clans, if the other races do not accept her, then she can only cultivate in the same undeveloped wild land of the other continent, so with her qualifications of the five spirit roots, she may not be able to cultivate to the refining period.

Of course, Zhou Tong only has this idea, and as for how to do it, the two have to study it again. It's a pity that there can only be one matching formation at the Four Spirits Bright Altar, and the matching formation has already been arranged in the human world, otherwise, it would be possible to let Cheng Yao arrange a matching formation and teleport it to her in the air.

Zhou Tong's brain hole, Fang Huairan felt that it was very good, so when Zhou Tong was studying the elixir, Fang Huairan began to study the magic of witchcraft, fortunately, he didn't need to practice this technique, just borrowed the space teleportation ability inside, Fang Huairan believed that there should be no gain.

Two months later, Fang Huairan's transformation of witchcraft still had no clue, but Zhou Tong's Dan Fang had a lot of experience in research.

With the level of Zhou Tong's alchemy master, according to some common materials in the Pearl Star Realm, he slightly fine-tuned the cultivation pills of fire attributes and special attributes and the breakthrough bottleneck pills, and obtained the cultivation pills suitable for the Yin Yang Ghost Dragon Spirit Core, the Star Silver Armor Beast Spirit Core and the Golden Flame Spirit Ape Spirit Core in the hands of the two of them, as well as the pills that broke through the early to middle stage of the transformation of the gods, and the pills that broke through the middle to late stages.

As for the Dan Fang that broke through the advanced refining of the Void in the late stage of the Transformation of the Gods, Zhou Tong did not deduce it, because such a Pill required at least two spirit cores of the Extraterritorial Heavenly Demons in the early stage of refining the Void, and the highest level in the hands of the two of them was the spirit cores of the late stage of the Transformation of the Gods, so even if Zhou Tong worked hard to deduce it, there was no way to verify and refine it.

However, according to the newly deduced Dan Fang, the two of them also need to go to Feihong City to buy some auxiliary alchemy common elixirs. The two of them discussed and decided to go to Feihong City to buy the auxiliary elixir of alchemy first, and then take the teleportation array to the nearest peak of Leiduo in the Yellow Emperor Realm to guide thunder.

Although both of them thought that the lightning would not be successful, what if they could succeed in guiding the thunder! Then the two of them would not have to work so hard to get the pill for cultivation, as long as they found the pill that broke through the bottleneck, then they could cultivate all the way unimpeded.

After deciding to do it, the two of them simply cleaned up, left the Frost Leaf Villa, and headed for Feihong City.

……

More than a month later, Fang Huairan and Zhou Tong returned to the Frost Leaf Villa together, and as soon as they returned to the villa, the two fell asleep on the bed.

It wasn't until three days later that the two of them got up, cheered up and began to cultivate.

During the previous trip to Feihong City, Zhou Tong successfully bought the auxiliary elixir he needed, but the trip to the Yellow Emperor Realm was not very smooth.

When Fang Huairan and Zhou Tong arrived at the thunderous mountain range in the Yellow Emperor Realm for a certain amount of money through the identity ring, they simply found a hidden place and began to guide the thunder.

Sure enough, it is similar to the thunder that was guided by the two of them in the Dongyang Realm before, and the thunder and lightning near the ground are not very powerful, but the transformed heaven and earth vitality are all thunder attributes, and after flying high, the power of thunder and lightning Yin Yang gourd can't bear it.

However, the Heaven and Earth Xuanhuang Pagoda can be better, after all, its prohibition is much more complete than the Yin Yang Gourd, but even if Zhou Tong uses the Shangyuan Zixiao Divine Thunder to attract thunder and lightning to quickly inhale into the tower, it still can't last too long, and the efficiency of transforming thunder and lightning can reach one-eighth, but it is also worth the loss.

The two of them reluctantly gave up the thunder, followed the original path, teleported all the way back to Feihong City, and honestly flew back to the Frost Leaf Cave Mansion, still preparing to refine the elixir, after all, the two of them had more than ten spirit cores of the Golden Flame Spirit Ape in their hands, and there were also several spirit cores of the Yin Yang Ghost Dragon and the Star Silver Armor Beast.

Through the teleportation array of the Frost Leaf Villa, the two came to the alchemy room of the Frost Leaf Cave Mansion, Zhou Tong took out a Golden Flame Spirit Ape spirit core in the early stage of the transformation of the gods, and took out the auxiliary elixirs he needed after fine-tuning the pill formula, and placed them in the alchemy room one by one.

Looking at the raw materials that had been arranged, Zhou Tong nodded with satisfaction, took out the Tianfeng Phantom Fire Ding, opened his mouth and spit out a wisp of baby fire, and began to warm up Xiao Ding.

Zhou Tong looked at the Heavenly Phoenix Phantom Fire Ding, and said with a slight frown: "The Tianfeng Phantom Fire Ding is just a high-level imitation spirit treasure, and the alchemy is slightly insufficient, so you should get a spirit treasure-level alchemy furnace." ”

"There are no Lingbao-level alchemy furnaces in the shops in Feihong City, if you want to get them, then you can only refine them yourself, but I don't have the information on the refining of the Dan furnace, so I can't scrutinize it, wait for me to collect this information, and then design a refining method for the Lingbao-level Dan furnace by myself, and collect materials to refine one for you." Fang Huairan said.
