It contains various materials and treasures, and it is even said that there is a formation plate left by the Emperor of Xuantian.

Nie Feng has refined hundreds of formations in these seven days, and the surviving materials occupy half of the sea knowledge space, and most of the materials required for the Dragon Trapped Shoal Formation have been collected, but there is still one core thing missing, the puppet golden stone.

The puppet gold stone is also called the puppet heart, the necessary thing to refine the puppet, in the dragon trapped shoal array, this puppet gold stone can condense those guardian puppets. There are good and bad puppet hearts, and it is said that the best puppet hearts can be used as the core of emperor-level puppets, comparable to emperor-level powerhouses, and the puppets made by the worst puppet hearts can't even beat those who open the pulse realm.

Nie Feng doesn't need a puppet heart that is too high-level, just a second-order nine-star one. His pace was fast, and after a quarter of an hour, he was outside the Xuantian Treasure Vault.

The hall of the Xuantian Treasure House was like an ancient pawnshop, and when you entered the door, you saw a high counter, and behind the counter, a young man was dozing off, paying no attention to the students who came to exchange treasures.

The young man Nie Feng knew him, not someone else, but the person who taught the rules to this class of students at the beginning of the ladder six years ago. Nie Feng didn't bother him, and walked straight through the hall towards the warehouse of the Xuantian Treasure Vault.

The things in the Xuantian Treasure House are all protected by formations, and these formations are arranged by Xuantianzi, not to mention these students, even if the emperor-level powerhouse comes, they have to honestly follow the procedure.

Nie Feng walked through the warehouse in front of him, and stopped in front of the warehouse with the second-order nine-star materials written on the door, he opened the door with his student card, and saw rows of shelves, those materials were placed on the shelves Nie Feng quickly found the location of the puppet heart, and exchanged eight for each one thousand credits, and then he exchanged some other materials in the material room, adding up to a total of fifteen thousand credits.

He thought for a moment, made sure he hadn't forgotten anything, and headed outside, back into the hall again. Nie Feng walked to the counter that was as high as his chest, knocked on the counter, and said, "I'm going to enter the inner library." ”

The young man who was lying behind the counter and was sleeping opened his eyes suddenly, and the light in his eyes flashed, and he returned to normal, looked at Nie Feng and said, "It turned out to be you, no wonder you want to enter the inner warehouse, come with me." ”

Nie Feng was not surprised by this young man's recognition of himself, the memory of cultivators was very good, plus now some people in Xuantian Academy were maliciously slandering him, it was difficult for him to become famous, since he entered the Xuantian Treasure Vault, those students who entered and exited the treasure house all looked at him with strange eyes, as if they were watching a thief stealing the treasures of their home.

Nie Feng followed the young man, turned a secret door, and entered a secret room, in which there was a teleportation formation. They stepped onto the teleportation formation, the teleportation formation lit up, and disappeared into the secret room with their figures.

After the dizziness of the teleportation passed, Nie Feng looked at this inner library, the real Xuantian treasure house. Contrary to what he had imagined, the inner treasury of the Xuantian Treasure Treasury was not built in a basement, but an open-air treasure house. The superb Xuanjing Mine is exposed, and there are all kinds of genius earth treasures growing on the Xuanjing mine, and the air is filled with the fragrance released by these genius earth treasures, which makes people feel refreshed when they smell it.

But Nie Feng's face was not the ecstasy of seeing the genius earth treasure, but solemn, the danger everywhere around him had been stimulating his Divine Pangu battle body to tell him how dangerous it was under this seemingly peaceful environment.

The young man was very surprised when he saw Nie Feng's appearance, when he first entered this inner treasury, he was shocked by the genius earth treasures in the treasure house, and he couldn't help but want to pick these genius earth treasures, without realizing the danger of the treasure house at all. He secretly said in his heart: "He is worthy of being a person valued by the dean." ”

The young man made a mysterious aura, and countless paths appeared in the treasure house, he pointed to the path and said: "Go, walking along the path will not touch the formation, as long as you don't touch the formation, there will be no danger, you see what things you want to exchange, just use the student card to swipe." ”

Nie Feng nodded and stepped onto the trail, which he watched as he walked along the trail. The things in this Xuantian Treasury are even more terrifying than the legends of the outside world, Nie Feng felt a burst of coercion through the formation when he walked through a puppet gold and stone mine, and he immediately determined that the core of this puppet gold and stone mine may have generated a puppet emperor heart stone.

Beyond the open-air area, it is the finished product area, and there are various arrays, weapons, armor, warships, etc., all of which are high-quality products, of course, the corresponding price is high-quality, and everything is above 100,000 credits.

And Nie Feng found that there were really not many things that he could use with these finished products, because his current strength was too low, just like a five or six-year-old child holding a gun, I was afraid that he would not hurt people with this thing, but would hurt himself.

After walking around, Nie Feng already had a plan in his heart about what he wanted to change, and Nie Feng walked straight to the open-air treasure house, a desert place, and in this desert there was a finger-sized turquoise crystal.

He redeemed it for two hundred thousand points. This thing is called the Life Pole Crystal, which can be regarded as a crystal formed by the condensation of the Liquid of Life, but the formation can only collect the Liquid of Life, and it can never be condensed into the Polar Crystal of Life.

Life pole crystal is generally only produced in the place of death, the so-called thing pole must be reversed, there is no life in a radius of thousands of miles can generate life pole crystal, it is regarded as the condensation of the life force of this radius of thousands of miles, of course, this is only the worst life pole crystal, legend has it that the best life pole crystal is located, there is no life in that world, there is only endless yellow sand.

This life pole crystal is equipped with a soul summoning stone, which can be used to arrange a life awakening array, even if it is a corpse that has just died, it can be saved, this is what Nie Feng prepared to save Shi Hao. There is a soul summoner stone here, but that soul summoner stone is too high-level, the price is one million, not to mention that Nie Feng can't afford to exchange this soul summoner stone, even if he can afford it, he doesn't dare to use this soul summoner stone as a material for Shi Hao's life awakening array. The soul summoner stone can not only awaken the summoning soul, but also absorb the soul, using this soul summoner stone as the foundation of the formation, Shi Hao's soul is afraid that it will not be enough to plug the gap between his teeth.

The second place Nie Feng arrived at was the five trees, these five trees have the five attributes of fire, earth, metal, water, and wood, the five trees are perfectly combined to form a five-element formation, but among these five-element formations, it is not a similar five-element circulation, which is extremely splendid, but it looks a little ghostly.

"Weeping willow, fire fusang, yellow bell neem, black mountain acacia, northern poplar, these five elements ghost trees can form the Five Elements Heavenly Ghost Array with a little refining. ”
