In the dead of night, Liu Yu sat alone in the room, with a pot of steaming boiling water on the table, his face was slightly red, showing a hint of drunkenness, and he didn't know what he was thinking about, staring at the teapot on the table in a daze.

After sitting quietly for a while, Liu Yu sighed deeply, poured himself a cup of boiling water, and a few cups of light boiling water went down to his stomach, dispelling the drunkenness in his heart.

Liu Yu remembered the secret method of "Shuangdan Quenching Field" mentioned by Tian Lao in the teahouse at noon, and suddenly took out an animal skin scroll from the storage bag and spread it on the table, his face suddenly became cloudy, and then he fell into deep thought.

The reason why Liu Yu agreed with the old man to meet again tomorrow is because of this animal skin scroll, this animal skin scroll was obtained by Liu Yu from the dead Senior Brother Li many years ago when he was serving in Yannan City.

At the beginning, Liu Yu felt that this method was very ridiculous, most of it was nonsense, so he didn't care, and kept it in the storage bag.

Liu Yu was completely drunk at this time, and carefully looked at the content recorded on this animal skin scroll, and couldn't help frowning, the "Foundation Building Secret Technique" stated above was almost the same as what Tian Lao said.

It also requires two pills of "Tsukuji Dan", which also records a secret method of "quenching fields", and attaches a detailed recipe for preparing "quenching field spiritual liquid".

However, among the dozens of spiritual materials listed in this "Quenching Spiritual Liquid" prescription, there is no such thing as "blood-spotted black taro", which is also the reason why Liu Yu was suspicious of the old man, so he did not reply on the spot.

Is everything the old man said true or false? Is the method of "Shuangdan Quenching Fields" really a secret method of "building a foundation"? Liu Yu still expressed extreme doubts, but why would Senior Brother Li collect such a secret scroll about "Shuangdan Quenching Fields"?

Does this mean that the method of "Shuangdan Quenching Fields" is not groundless, and it makes Liu Yu have some inexplicable expectations in his heart.

After Liu Yu sat quietly for a long time, his eyes suddenly lit up, as if he had figured out something, and then he got up and put away the animal skin scroll on the table, blew out the candle, sat cross-legged on the wooden bed, meditated and concentrated, and after taking a "Hua Zhi Dan" and two "Lotus Fragrance Pills", he began to perform "Huang Mu Pei Yuan Gong", and luck melted the "Qi Burning Pulse".

Soon after, two warm medicinal forces rose in the abdomen, and the two medicinal powers were guided by Liu Yu's spiritual sense, circulating in the meridians, and impacting the qi scorching veins on the outer wall of the dantian together with the wood spiritual qi inhaled from the outside world. The end of the Qi scorching vein quickly softened and dissolved, making a subtle sizzling sound, and the cultivation effect was quite significant.

During this time, Liu Yu found that after returning to Beiluan City from the Black and White Mountain Range, for some reason, the cultivation effect suddenly increased a lot, and when he absorbed the spiritual energy from the outside world, not only was it extremely smooth, but the amount of spiritual energy he inhaled also increased by nearly fifty percent, as if his own qualifications had suddenly improved, which made Liu Yu both surprised and puzzled.

Liu Yu himself couldn't figure out the reason, and vaguely guessed in his heart that it might be because of the "Qingjing Spirit Honey" he had taken before, which greatly improved his qualifications, which enhanced his cultivation effect.

In fact, Liu Yu was not right, the "Qingjing Spiritual Honey" did purify Liu Yu's meridians, but the more important thing was the "True Yuan Fruit Qi" that he unintentionally absorbed when he was trapped in the "Prison Spirit Cave Mansion".

"Qingjing Spiritual Honey" and "True Yuan Fruit Qi" together improved Liu Yu's cultivation qualifications, and it is no exaggeration to say that Liu Yu's spiritual root qualifications at this time are no longer weaker than some inferior dual spiritual root cultivators.

The next day, Liu Yu rushed to the Qianfu Building early, with "beast blood", "crystal powder" to mix the "Fu water", when Shi Changming walked into the rune room, Liu Yu had already drawn a few semi-finished products of "Mu Yuan Dun", because he was going to meet Tian Qi in Wuhu Square at noon, Liu Yu thought about drawing more semi-finished talismans to reduce Shi Changming's burden.

At that time, Liu Yu took advantage of the rest time to come to the door of the drawing room of the steward Huang Jian, and respectfully shouted inward: "Senior Liu Yu asks to see!"

"Come in!" Huang Jian's voice soon sounded in the room.

After Liu Yu entered the house, he arched his hand and said, "Uncle Huang, I'm sorry!"

"Sit down, what's the matter with Senior Nephew Liu's search for the poor road?" Huang Jian beckoned Liu Yu to sit down at the coffee table and asked casually.

After Liu Yu sat down, he hurriedly replied: "The junior encountered something unknown yesterday, and I ask my uncle for advice!"

"Oh, what's the matter?" asked Huang Jian, pouring Liu Yu a cup of tea.

"Uncle Xie, I don't know if Uncle Xie knows the method of "Shuangdan Quenching Field"?" Liu Yu took the teacup with both hands, and then spoke.

Huang Jian's eyes suddenly lit up, and he came to his senses, and he raised his head and asked: "This magic sword is going sideways, it is extremely dangerous, how did you know about it, nephew?"

"The juniors ...... at Wuhu yesterday. Liu Yu carefully told Huang Jian what happened to the stall yesterday, as well as Tian Qi's remarks about the secret method of "Shuangdan Quenching Field".

It turned out that Liu Yu thought hard for a long time last night, and he didn't figure out how to reply to Tian Qi tomorrow. Because Liu Yu didn't know whether the secret method of "Shuangdan Quenching Field" he said was true or false. And the "black bump" in his hand, is it really a piece of "blood-spotted black taro" as he said? Or is it something else that is precious?

In the end, Liu Yu had a flash of inspiration, and instantly figured out that he was inexperienced and couldn't recognize what the "black bump" in his hand was, so he could ask the seniors of the sect for advice! No, Liu Yu rushed to Qianfu Tower early in the morning.

When Liu Yu decided to ask the seniors of the sect, the first thing that came to mind was Huang Jian, the steward of the Qianfu Building. First, Liu Yu is now a "Fu apprentice" in Qianfu Building, and he has some contact with Huang Jian on weekdays, and it is easier to get in touch. Second, Liu Yu's ten acres of fertile land in East Lake were leased to the Huang family, and with this relationship, the two could talk.

"What is the "blood-spotted black taro"?, take it and take a look. After listening to Liu Yu's story, Huang Jian couldn't help but say curiously.

Liu Yu hurriedly took out the "black pimple" from the storage bag, handed it to Huang Jian and said, "Uncle Shi, please take a look!"

This thing resembles a "black potato", but the color and skin are very different, and the poor road has never seen it, as for whether it is the "blood-spotted black taro" in the mouth, the poor road is not easy to draw conclusions. Huang Jian looked at it carefully, then said with a frown.

"This..."Liu Yu was speechless for a while, not thinking that even Huang Jian, who was in the foundation building period, couldn't tell what this "black bump" was.

Huang Jian couldn't help but be a little embarrassed when he saw Liu Yu's surprised face, and then said: "Although Poor Dao doesn't know what this thing is, the essence of the plants and trees contained in this thing is extremely light, and the aura emitted by it should not be some kind of rare spiritual material. ”

"Does that mean that Tian Daoyou didn't panic, this thing may indeed be the "blood-spotted black taro"?" Liu Yu couldn't help but be stunned for a moment, and then immediately asked.

Huang Jian nodded and replied, "That's right, nine times out of ten, that person is telling the truth, and this thing may indeed be of great use to him." ”

"Uncle Shi, is it true that the secret method of "Double Dan Quenching Field" that Tian Daoyou said? This method really has a miraculous effect on "foundation building"?" Liu Yu asked a little impatiently.

Huang Jian chuckled and glanced at Liu Yu and said, "How much do you know about the method of "Shuangdan Quenching Field"?"

"I don't know much, I'm just a little curious!" Liu Yu noticed that he was a little out of shape, and said uprightly.

Huang Jian took a sip of tea and said slowly: "The method of "Shuangdan Quenching Field" has existed since ancient times, according to ancient books, it was only circulated in a few scattered cultivators at first, after all, this method is too dangerous to say that it is a desperate fight, but after countless predecessors who are not afraid of life and death, they have practiced by risking their lives, and the improvement has been perfected little by little, and it has become a secret technique with a very high success rate of foundation building. ”

Huang Jian paused, and then sighed: "The 'Shuangdan Quenching Field' became famous for a while, and it is no longer only circulated among the scattered cultivators with mediocre qualifications, but the major sects of the Eastern Yuan Continent have all used this method. During the period when the "Shuangdan Quenching Field" was prevalent in ancient times, the success rate of foundation building in the entire cultivation realm was as high as sixty percent, and the foundation building period cultivators appeared like bamboo shoots after the rain, and the foundation building cultivators at that time were as ordinary as the current Qi cultivation disciples. ”

Liu Yu's eyes widened at this time, and he was speechless in shock by what Huang Jian said, and only after a long time did he come back to his senses and asked suspiciously: "Uncle Shi, why is the success rate of foundation building in the cultivation realm so low now?
