"Officer Ouyang, in addition to sending these things, you should have something to do, right? A few days ago in the ward, you said that you would look for me for a few days, did I ask you to help find the things you helped find found them?" Qin Tian looked at Ouyang Ruoxue with some expectation in his eyes.

"Hmm!" Ouyang Ruoxue nodded, "The Sumeru Stone I told you last time was found, but the other material, Tianyin Sand, was not found, but my father asked me to tell you a piece of news, in ten days, there will be a small treasure exchange meeting in Chuanzhong, and many martial artists and families will participate, and there may be Tianyin Sand you need." ”

As she spoke, Ouyang Ruoxue took out an object again from the satchel she was carrying.

It was a fist-sized stone, the surface was silvery-white, and there were many cavities all over the body, roughly counting dozens of them, and the volume of the stone was obviously very small, but looking through the hole, it was found that it was extremely dark inside, as if connecting a bottomless abyss, which was very magical.

"Sumeru Stone!"

Qin Tian's face was overjoyed, he didn't even need to take it for identification, just by looking at the stone in Ouyang Ruoxue's hand, he already knew that it was the Sumeru stone he needed, and only the Sumeru stone would form such a strange situation.

"I brought you something, when will you give me those vein refining grass?" asked Ouyang Ruoxue.

"I happen to be busy these days and can't leave for the time being. In this way, I happen to have some essence medicinal juice made from vein refining herbs combined with other precious medicinal materials, the effect is many times better than the medicinal materials that come out of vein refining herb juice alone, I will give you some, it should be regarded as the refining vein grass needed to compensate for the Sumeru stone, how about it?" Qin Tian thought for a moment and said.

The essence medicinal juice that Qin Tian said was the one he had refined during his time at Hua Tiandu's house, and the effect of strengthening the meridians was much better than using the vein refining herb alone, and a large part of it had already been taken by him.

Ouyang Ruoxue seemed to believe Qin Tian very much, and quickly nodded and said, "Okay!"

Qin Tian immediately returned to the room and soon came out with a small jade bottle, which contained dozens of drops of medicinal liquid.

"So little?" Ouyang Ruoxue frowned, the medicinal liquid in the jade bottle was too little.

"It's already quite a lot! One drop of these medicinal liquids can be worth a hundred vein refining grasses, there are dozens of drops here, how many vein refining grasses do you say are worth?" Qin Tian smiled lightly.

"One drop is worth a hundred vein refining grass!?" Ouyang Ruoxue opened her mouth in surprise.

"That's right! If it weren't for the happy relationship between us, I wouldn't want to give you these essence potions!" Qin Tian nodded.

"Thank you!" Ouyang Ruoxue clutched the jade bottle tightly in her hand.

Recently, as more and more medicinal liquids were taken, the effect of refining the veins and herbs to strengthen the meridians was getting weaker and weaker, and it could even be said that there was no strengthening effect, otherwise Qin Tian would not have given out the essence of the medicinal liquid so lightly.

It stands to reason that the effect of the vein refining grass should not lose its effect so quickly, but it will only be like this in the late stage of qi training, but this happened to him, Qin Tian has never been able to understand it, and in the end it can only be attributed to the "Star Alchemy", "Star Alchemy" is a supreme body refining technique, and the strengthening of the meridians is naturally not weak.

For these vein refining grasses that had lost their utility to him, Qin Tian had thought of simply handing them over to the family behind Ouyang Ruoxue, or the national organization behind Chen Chen, in exchange for their favors.

After all, in China, the most important thing in the interaction between people is human favor, no one wants to owe others favors, generally after owing others favors, they will try their best to return the favors, only in this way will they feel comfortable.

But then Qin Tian thought about it and completely snuffed out this idea.

The human heart is the most difficult thing to figure out, and no one can guarantee that the human heart will never change, maybe one second they will call you brothers, and the next moment they will stab you a few times.

Moreover, although these vein refining grasses are already like waste grass to themselves, they are very precious treasures for others, such a large amount of precious resources are not in their own hands and exchanged for more benefits with others, but are given away in vain, wouldn't he become the No. 1 big fool in the sky?

After Ouyang Ruoxue left, a thoughtful glint flashed in Qin Tian's eyes: "Ten days later, the treasure exchange meeting in Sichuan, I don't know if there will be any gains?"

Qin Tian shook his head, temporarily expelling these thoughts from his mind, the most important thing now is to deal with these fire attribute heaven and earth treasures first, and let Phoenix Yan devour and grow.

Coming to the basement again, Qin Tian opened the suitcase, only to see that the suitcase contained more than a dozen fire-attribute heavenly and earthly treasures, but these heavenly and earthly treasures were only some relatively low-level heavenly and earthly treasures.

It's not that Qin Tian doesn't want high-grade Heavenly Materials and Earth Treasures, but he knows that it is impossible to find high-level Fire Attribute Heavenly Materials and Earth Treasures on this earth where the spiritual energy of Heaven and Earth is thin, even if it is the low-level Heavenly Materials and Earth Treasures he needs, there are still several things that are not in it.

As soon as Qin Tian raised his hand, Huang Yan appeared in his hand, picked up a fire attribute heaven and earth treasure and threw it at Huang Yan, Huang Yan rose suddenly, devouring that fire attribute heaven and earth treasure, and instantly changed into flying ashes.

It didn't take long for all the fire attribute heavenly and earthly treasures in the suitcase to be swallowed up by Phoenix Flame, and Qin Tian also felt that the spark in the center of the flame had grown a little.

The real core of Huang Yan is the spark in the center of the flame, and the outer layer of flame is just the formation of the power emitted by Huang Yan, only when all the flames are composed of sparks from the core, then Huang Yan is really 'Huang Yan'!

............

Time passed in a hurry, and it was the day of Wu Yuanyuan's birthday in a blink of an eye.

On this day, Wu Zhengang sent someone to Qin Tian's villa early to pick up Qin Tian to his home.

Wu Zhengang's home is located in another villa area in the city, and his home is a few points larger and more luxurious than Ye Jun's, and it is full of a luxurious atmosphere.

"Master Qin, thank you so much for giving the little girl a talisman, the little girl doesn't have nightmares when she sleeps at night these days. As soon as Qin Tian got out of the car, Wu Zhengang greeted him and said with a grateful face.

"Thank you, Master Qin!" Wu Yuanyuan also walked over.

"It's too early to say thank you, wait until that ghost is destroyed. Qin Tian said lightly.

"Yes, Master Qin, please!" Wu Zhengang nodded again and again, leading the way in front.

In the living room of the villa, Qin Tian saw a person who was not supposed to be here.

"Brother Ye, why are you here?" Qin Tian looked at Ye Jun in surprise, who was smiling and waving at him.

"Brother Qin Tian, you came here to slay demons and eliminate demons, how could I miss it?" Ye Jun said with a smile.

"There is danger here, you shouldn't come!" Qin Tian's face was solemn, there were already Wu Zhengang's father and daughter here to protect themselves, if there was one more Ye Jun, he would not be able to protect him at all, in case Ye Jun was injured, then how could he be happy.

"Brother Qin Tian, there is a legendary ghost tonight, not everyone has such an opportunity, besides, I still have the talisman you gave me, I will be fine, you just let me stay!" Ye Jun's eyes flashed, it was a kind of pursuit of excitement.

Qin Tian sighed in his heart, he knew that he wouldn't listen to anything Ye Jun said, so he had to take out a few evil talismans and fireball talismans that he had made in the past two days and give them to him, and taught him how to use them, in case of any accidents, so that he could have some ability to protect himself.

Looking at Wu Zhengang's father and daughter who were looking at him with a hopeful look on the side, Qin Tian only gave them a few evil talismans, and did not give them fireball talismans, but even so, Wu Zhengang's father and daughter, who got the evil talismans, also thanked Qin Tian again and again with a happy face.

Since it was still some time before it got dark, Wu Zhengang invited him Qin Tian to visit his villa.

During his visit to the villa, Qin Tian learned that Wu Zhengang was also a collector of strange stones, and that there was a huge room in his villa dedicated to all kinds of strange stones he had collected.

This room is very large, nearly 200 square meters, inside are glass cabinets several meters high, these glass cabinets are placed in Wu Zhengang's collection of strange stones for many years, dazzling, like a strange stone exhibition.

"This, this is ......" At this time, Qin Tian was standing in front of a glass case, looking closely at a stone inside, with an unconcealable excitement in his eyes.

The stone was about the size of two fists, red all over, with lines on the surface, which looked like a flame was burning there, and on the stone there was a thumb-sized crystal, as if it had grown out of the stone, the crystal was as red as blood, emitting a faint red light.

From that small crystal, Qin Tian could feel a very large amount of fire attribute energy, which was formed by the high degree of compression and condensation of countless fire attribute energy, which was a treasure of fire attribute.

Flame Crystal!

Qin Tian's mind quickly flashed the information of that thumb-sized crystal, the Yan Crystal was a treasure that could only be formed in an extremely high temperature environment, it was very rare, if Huang Yan could devour this Yan Crystal, he would definitely be able to more than double in size!

"Master Qin, do you like this stone?" Wu Zhengang couldn't help but ask when he saw Qin Tian staring blankly at a crimson stone in the display case.

"Where did you get this stone?" Qin Tian asked.

"This is a gift from a friend of mine! My friend likes to explore some strange places, and it is said that he found a hidden tunnel in Changbai Mountain, which leads to the depths of the earth, to a molten cave underground. This stone was a souvenir he got there, and he gave it to me knowing that I liked to collect exotic stones. Wu Zhengang recalled and said.

Qin Tian groaned slightly, it seemed that after he went to central Sichuan, he was going to Changbai Mountain.
