Lu Tong and Old Man Tianxin appeared outside Lu Tong's residence again, and at this time, Old Man Tianxin did not leave immediately, but turned to look at Lu Tong without saying a word!

After a long time, the old man of Tianxin let out a long sigh and said to Lu Tong: "Although the Soul Continent is said to be a formation mage, an alchemist, and a refiner, it is not too many, because once these people specialize in cultivating one of them, then it is impossible for him to devote more energy to cultivation!

Lu Tong smiled slightly and said, "Master, don't worry, I will definitely not delay my cultivation!"

The old man of Tianxin smiled slightly: "I'm not worried about your cultivation, your star soul vein is destined to go further than others on the road of cultivating immortals! It's just that I'm worried that once you can't devote yourself to cultivation after refining the formation and refining medicine, it will affect you a lot!"

Lu Tong smiled at the old man Tianxin and didn't speak, but Lu Tong secretly thought to himself that if the four elephants of reincarnation in the inner world can be used now, why should he be afraid of lack of time, in the four elephants of reincarnation, ten days have only passed in the outside world, but I don't know why the four elephants of reincarnation are still unable to enter.

The old man Tianxin looked at Lu Tong blankly, he thought that Lu Tong had entered a dilemma, shook his head lightly, patted Lu Tong's shoulder and said, "Believe in yourself, only if you have confidence can you go further on the road of cultivating immortals!"

Lu Tong, who came back to his senses, nodded, and the old man Tianxin smiled slightly and said, "You rest first today, and I'll go to Feng Wu and ask him to take you away tomorrow!"

Lu Tong wanted to say something, but after all, he didn't open his mouth, nodded and walked towards the residence, after more than half a year of refining, Lu Tong was already basically familiar with all kinds of medicinal materials, as soon as he entered the door, he smelled a faint fragrance, closed his eyes, raised his head slightly, and said with a smile: "The dark fruit flower and purple orchid grass are really refreshing!"

Lu Tong slowly walked to the incense burner and opened it to take a look, and sure enough, there were burning fruit flowers and purple orchid grass inside! After putting the incense burner away, Lu Tong walked to the side of the bed and sat cross-legged......

The next day, Lu Tong, who was still meditating, clearly felt that the aura fluctuations around him were stronger than yesterday, but between breaths, Lu Tong smiled and said, "I never thought that I would break through to the immortal master like this!"

And at this time, Yu Luo and Wang Yi, who were about to come to call Lu Tong, stopped not far away, because they also clearly felt the fluctuations of the aura around them, at this time, the old man of Tianxin instantly frowned, and instantly flashed to Lu Tong's door and threw a purple stone into the house, and in an instant, the aura skyrocketed a few points, and at this time, the old man of Tianxin slowly took a few steps back!

Time passed minute by minute, and the aura in Lu Tong's house only decreased but did not increase, at this time, the old man of Tianxin released his divine sense to observe Lu Tong and found that Lu Tong was at the key to breaking through, and instantly quickly took out two purple stones and threw them into Lu Tong's room, and in an instant, the aura skyrocketed again!

Lu Tong, who was in the state of breakthrough, already felt that the aura was not enough, and when he was in a hurry to break through the key, the aura in the room instantly skyrocketed again!

It is also strange that Lu Tong has long been able to feel the aura fluctuations but has not been able to absorb it, why can he wantonly absorb the aura between heaven and earth when he breaks through now, so Lu Tong can't figure it out, but now at the most critical time of breakthrough, if he is not careful, he will let the demons take advantage of it, so Lu Tong has to work hard to concentrate on breaking through!

At this time, Yu Luo, Wang Yi, Old Man Tianxin, Feng Wu, and even the evil wolf outside Lu Tong's room were all standing outside the door and waiting quietly!

The old man of Tianxin frowned slightly and said, "It shouldn't be that Immortal Venerable didn't want so much aura to break through for so long, I lost three purple spirit stones into it." ”

Wang Yi and Yu Luo said in unison: "Purple Spirit Stone, what is Purple Spirit Stone?"

The old man of Tianxin smiled and said, "You will come into contact sooner or later, I wanted to tell you when you leave today, so I'll tell you two about it now!"

At this time, the old man Tianxin took out a purple stone from his arms and said: "This is called the purple spirit stone, which can quickly replenish the monk's aura, and can also improve the aura of a fixed small area around us! We also inadvertently found that because there are too few top-grade blue-bloodstones, and there is not much spiritual energy in the top-grade blue-bloodstones, every time we cultivate, there is no trouble, and the appearance of the purple spirit makes the monks salivate!"

Yu Luo looked at the old man of Tianxin and smiled slightly: "Your old man is talking about what this purple spirit stone has to do with the blue blood stone!"

The old man of Tianxin easily threw another purple spirit stone into it, and felt that the aura around him had increased again, so he said slowly: "Actually, the purple spirit stone, every big cultivator of the True Sect will make it, but it takes a lot of time to make this thing, and it can't be done in large quantities without absolute patience!"

At this time, even Wang Yi asked in surprise, "Are you saying that the alchemist can extract the aura of the blue blood stone and then refine the purple spirit stone?"

The old man of Tianxin shook his head and said, "It's not what you think, you can't extract the aura of the blue blood stone!"

Wang Yi thought for a while, didn't speak, but waited for the old man Tianxin to continue, and the old man of Tianxin sensed the aura around him before he continued: "The monks of the Soul Continent all know that blueblood can be mined by anyone, but over time, the relatively large veins that can mine high-grade blueblood stone have been taken by the major cultivators as their own and used to reward the sect people, only some veins with poor quality have been used by some families, mountain villas, And the peaks are mined in turn, and a small part of the veins are mined by scattered cultivators, you also know that most of the people who mine bluestone are relatively low cultivation monks, they mine some of the blueblood stones for cultivation, and some of them are used to exchange for items, only the major cultivation sects will send some monks and let mortals who can't cultivate to mine!"

When he said this, the old man of Tianxin frowned, threw another purple spirit stone in, and then continued: " Over time, because the competition for the blue blood stone vein is getting more and more fierce, many scattered cultivators are going to some places with little population to try their luck in groups, but there are many demon beasts in deserted places, and those demon beasts are not as good as the demon world, they can not attack the monks casually, most of those demon beasts are extremely fierce, and over time, there are more and more scattered cultivators looking for blue blood stone to sell to the major cultivators, so that they can not only get the blue blood stone they need for daily life, but also have some good income. ”

Wang Yi suddenly asked, "What can these mean?"

The old man of Tianxin smiled slightly: "Don't worry, you must understand these things clearly!"

At this time, the old man Tianxin sensed the aura around him again, and then nodded reassuringly, and continued: " With the passage of time, an accidental incident allowed the monk to come into contact with the purple spirit stone, this kind of stone is purple itself, and it is not much use, and put him and the blue blood stone together, and then add the alchemist's deployment, you can actually transfer the aura of the blue blood stone to the purple stone, this kind of purple spirit stone can absorb the upper, middle and lower grade blue blood stone aura at will, as long as the aura is enough to store the purple spirit stone, each purple spirit stone with good color can absorb a hundred high-grade blue-blood stones, and those with bad color can also absorb fifty high-grade blue-blood stones, and even the purple spirit stone with the worst color can absorb nearly twenty-five high-grade blue-blood stones。 Therefore, according to the fineness, the purple spirit stone is also divided into three grades: upper grade, middle grade, and lower grade!"

Wang Yi was shocked: "Are there a lot of purple stones?"

The old man of Tianxin smiled slightly: "At least there are more than blue-bloodstones, and they are easy to find, but the purple spirit stones that can absorb a hundred high-grade blue-bloodstones are relatively few, but they are relatively easy compared to the top-grade blue-bloodstones." ”

Wang Yi said: "Then why are there so many monks fighting for the best blue blood stone, and it is not good to replace it directly with purple spirit stone?"

The old man of Tianxin smiled slightly: "If it is really like what you said, then do you think the small family and those scattered cultivators can still collect blue blood stones?"

Wang Yicai came back to his senses and said, "Is the success rate small?"

The old man of Tianxin smiled slightly: "This is one of the reasons why it can only be refined by alchemists and lotus, and it is not widely spread. ”

Wang Yi looked at the old man of Tianxin and waited for the next sentence silently, and the old man of Tianxin continued: "When the two are fused, we must pay attention to the heat and timing, otherwise not only will the aura of the blue blood stone all dissipate, but you may also suffer a lot of injuries!"

Wang Yi was surprised: "Will you still be injured if you refine it?"

The old man of Tianxin nodded and said: "There is a risk to everything, and the purple spirit stone is the same! The purple stone dug up is different in color and size, and the spiritual energy it bears is also somewhat different, so that although the purple spirit stone can be compared to the best blue blood stone, it is still the reason why few people use it, because most of the alchemists have a strange temper, how can they spend most of their time refining the purple spirit stone, at most, it is used to refine some when cultivating the fire!"

Wang Yi nodded and said, "So that's the case!"

At this time, he suddenly heard Lu Tong screaming in pain in the room, and the old man Tianxin, Wang Yi, Yu Luo, and even Feng Wu and the evil wolf all frowned at the same time.

The old man of Tianxin released his divine sense to perceive Lu Tong, and found that Lu Tong was screaming in pain on the ground, and the color of his body would be red, cyan, and white from time to time, and three colors would appear on Lu Tong at the same time!

At this time, the frightened old man Tianxin couldn't care so much, broke through the door with his aura, and quickly entered, stopping not far from Lu Tong's side, and then Wang Yi and the others who came in were standing quietly beside the old man Tianxin.

After a long time, the old man Tianxin said while watching Lu Tong scream in pain: "Wang Yi, have you ever been in such a situation with him recently?"

Wang Yi was still thinking about how to answer, when Yu Luo suddenly said nervously: "Xiao Tong appeared like this when he was in the Ice Mist Holy Sect, and then the Shadow Immortal Venerable said that his White Tiger bloodline was growing!"

The old man of Tianxin nodded and said: "In terms of the three colors, red should be the color of transformation into immortal qi after being promoted to immortal master, white is the color of the white tiger's talisman, and cyan should be the talisman color of the green dragon, is there any relationship between the Tianlong bloodline and the Qinglong line?"

The old man of Tianxin fell into deep thought at this time, while the others looked at Lu Tong who was in pain on the ground with concern as they watched the old man of Tianxin's actions, praying that Lu Tong would definitely be able to save the day.

The most worried is Yu Luo, at this time, Yu Luo grabbed Wang Yi's arm tightly and closed his mouth, looking at Lu Tong who was screaming in pain on the ground with a complicated expression......
