After the garden, it is a stone house. Entering the stone house, you can see the smell of herbs transpiring inside. Su Chen knew that this was the place where the temple was refining medicine. The temple refining medicine is significantly different from that of the human race. Their refining method is to mash them into a paste with the most primitive method after collecting the materials, and apply them in the form of smearing. This is the lowest-level method of refining medicine and medicine, and the human race can basically ignore it. However, the temple refining medicine is not without its merits. These guys have boiled medicine for tens of thousands of years, and they have a set of methods that can preserve the medicine to the greatest extent. They are unique in the preservation and rough processing of medicine. Su Chen had long been salivating over the temple's potion-boiling technique, but he never had a chance to get it, even if he captured Rena, it was useless. But now, he can finally plunder the temple secretly. Most of the refining techniques of the temple are recorded on bone books, which are books made of special bones. Each piece is as thin as a cicada's wing, capable of writing words, and is immortal for a long time. There are hundreds of bone books on refining knowledge in the medicine hall. Su Chen is not welcome, and he puts them in the source ring without seeing them. After giving the Tianwei army a large amount of food, his source ring is Free enough. After scouring the pharmacy books, Su Chen kept going to the next place. On the right side of the stone house is a huge palace made of bones. Entering the hall, the first thing I saw was a mob teenager, who looked like a candidate for sacrificial apprenticeship, dressed in a white robe, and of a very young grade. He saw Su Chen coming and gritted his teeth and rushed towards him. Su Chen didn't talk nonsense, he just held down the young man's head and twisted the young man's head just like that. After killing the young man, Su Chen came to the White Bone Hall and saw skulls piled up everywhere, most of which were human skulls, but there were also some mob skulls. In addition to the skull, there are neck bones, arm bones, leg bones, etc. These bones seem to be messy, but in fact they hide order and put them in different categories. Su Chen knew from Rena long ago that different bones here have different functions. For example, the skull is used to store the soul, practice witchcraft, the arm bones and leg bones are used for divination and interrogation bones, and the neck bones can be used as medicine, and they have many uses. Su Chen is not interested in these bones, but there is a large wall behind the White Bone Hall, and the wall is full of mysterious spells. These spells are really the key to the temple's bone-strengthening. There are more than a thousand tribes in the mob, and each tribe has its own bone-questioning spell, most of which are common, but there are also a small part that is unique to the tribe. Those common spells, Su Chen, have been obtained from Rena, but the unique spells of each tribe can only be obtained by going to the temples of each tribe. Fortunately, there are not too many of this part. Su Chen only glanced at it, and then distinguished that those were the unique spells of the Winter Tribe, and had already written them down one by one. After doing this, Su Chen will go to the next place. This time it was a big pit, and there were corpses piled up in the pit. There were human corpses, mob corpses, and monster beast corpses. The most shocking thing is that at the top of the corpse pit, there is still a bright phantom. Spirit Race! It was a spirit race who was detained above the corpse in a special way, and didn't know what method was used to prevent the spirit race from escaping, just like a ghost fire, wandering in the corpse endlessly. Seeing this weird situation, Su Chen's footsteps also slowed down significantly. He approached carefully step by step, and stopped when he was three feet away from the corpse. "A spirit race was actually locked into the temple by the mob. This is a rare scene." Su Chen said slowly. "Save... I..." The Spirit Race groaned like a groan, and stretched out a crystal-transparent arm towards Su Chen. "Sorry, I only killed the Spirit Race, but I didn't save the Spirit Race." "I can... give you what you want..." "Then you have to know what I want." "Power..." "Answer wrong." Su Chen sneered. He looked at all the surrounding arrangements, as well as the countless characters imprinted around the spirit race, and he already had a few answers in his heart. "A suction ritual, they are continuously pumping your soul energy." Su Chen whispered. This spirit race is obviously used as a victim of a certain ritual. Its huge soul energy is exactly what the mob race needs. As for the dead in the corpse, they are used to supply the spirit race and make it immortal. . In a sense, this spirit race is like a soul energy converter, which continuously collects and transmits the soul energy of various lives. What kind of ritual is needed to make these mobs kill so many lives to do this? Even Su Chen was curious. "Knowledge, endless knowledge!" The Spirit Race shouted again. "You don't have endless knowledge yourself, and you deserve to talk about it to me?" Su Chen shook his head. "But I have enough!" The Spirit Race shouted without letting go of expectation. This is true. Any spirit race is a person of profound knowledge. Because their life span is endless and they are dedicated to research, it can be said that each spirit race is a rich library. "Sounds really good, but the premise is how do I control you?" "I can open my soul guard to you and let you plant a soul imprint." Su Chen replied, "A good technique, but unfortunately I don't know this technique. The Spirit Race hurriedly said: "I will teach you. Let go of the sea of knowledge, and I will pass on this part of the knowledge directly to you. This kind of transmission cannot be faked, and you will understand if you get it." "Really?" Su Chen pondered. stand up. "Believe me, I just want to get rid of this suffering, even as a slave, it's better to endure this kind of torment!" The spirit race shouted, "It does no harm to you to have a slave like me." "Well then, let me try. Try, but you'd better don't mess around." Su Chen replied. "Grab my hand!" the Spirit Race shouted. Su Chen stepped forward and grabbed the hand of the spirit race, and the two hands were joined together, and a huge flash of light was emitted from the spirit race. "Let go of your consciousness, I will pass on to you the knowledge about soul imprinting." The voice of the Spirit Race said leisurely. Su Chen closed his eyes and let go of Zhihai. With the opening of his sea of knowledge, a strong consciousness suddenly rushed into his sea of knowledge. "Hahahaha, you idiot! Give me your body!" The spirit clan's rampant roar resounded in Su Chen's mind. "Sure enough, you just want to take this opportunity to take my body, don't you?" Su Chen sneered. "That's right!" The spirit race laughed loudly: "Although I have to abandon my immortal spirit body for this, it is better than being your servant. Don't worry, I will continue to survive as you in the future, and even help you out. A bigger prestige!" "Thank you, but I still don't bother you." Su Chen said coldly: "But a spirit race with a soul energy of 2,500 points has endured such a long period of torture. I really want to see it. Look, how can you take my body away!" As he spoke, Su Chen's eyes widened sharply.
