The sweeper chuckled, “The Thunderfire Forging Meridian Heart Sutra requires the power of thunder and fire to scorch the meridians! The cultivation process is excruciatingly painful! Moreover, if one's physical body is not strong and one's willpower is not firm, it is difficult to succeed in cultivating it! Therefore, this technique has not been cultivated by anyone for hundreds of thousands of years! I have heard that you, Sect Master, used the power of thunder and fire when refining pills. With this divine object, you will surely be able to cultivate the Thunderfire Forging Meridian Heart Sutra! However, I must also advise you, Sect Master! Due to international conventions, people with cultivation levels above the Nascent Soul stage are not allowed to run wild here in the Three Rings Continent! But the rules are set by the leaders! Immortal Venerables and Immortal Saints may not come here, but there is no guarantee that Immortal Emperors will come! Do you understand what I mean?”
Lin Caogen nodded and said, "I understand! What you mean is, 'A common man is innocent, but possessing a treasure is a crime.' The rules are all set by the leaders! They can only manage their subordinates, not their leaders!"
The old sweeper laughed, "That's right! If it were a Celestial Emperor who knew that the Sect Master possessed a rare treasure, he might shamelessly try to snatch it! Enough with the nonsense! Sect Master, please! The Thunderfire Forging Vein Heart Sutra is hidden in the basement of the Scripture Pavilion! This is the key to open the basement! Today, I will hand this key to you, Sect Master!"
After saying that, the sweeper took out a six-pointed star iron block from his pocket!
Lin Caogen took the iron block and felt that it weighed a thousand pounds! It was only the size of a small palm, yet it had such weight. This thing was extraordinary!
Lin Caogen put the key into his immortal abode and pushed open the door of the scripture pavilion, slowly walking inside.
This was his third time entering the Sutra Repository! He had been there twice before when he was a disciple of the Wuwei Sect, browsing through the books! But he had never been to the basement of the Sutra Repository! No one was allowed to go in there!
Following the steps, Lin Caogen quickly arrived at the underground level!
The basement was incredibly spacious, like an underground palace! The floor tiles were all high-quality microcrystalline tiles, smooth and translucent, comfortable and springy to walk on! Wall lamps, all perpetual oil lamps, hung on the surrounding walls, exuding a rustic and ancient yet luxurious feel.
Looking around, Lin Caogen noticed a hole in the very center of the basement! The hole was about the size of a palm! It seemed to be where the key was kept!
Lin Caogen came to the center, took out the six-pointed star iron key weighing a thousand catties, and slowly placed it at the entrance of the cave!
The six-pointed star iron key slowly sank down, fitting perfectly into the opening!
"The craftsmanship is amazing! The fit is perfect, comparable to fine carving!"
Lin Caogen couldn't help but exclaim in amazement!
As the iron block sank completely into the hole, the entire microcrystalline brick floor became incredibly smooth and seamless!
Just then, six-pointed star patterns suddenly appeared on the ground! The spot where Lin Caogen was standing began to slowly sink!
Like an elevator opening!
Lin Caogen sank 300 meters deep while standing on the microcrystalline brick floor! Only then did he stop!
What comes into view is a large door!
Lin Caogen pushed hard! The 10,000-pound iron gate was slowly pushed open!
Good heavens! This is an underground palace! Incredibly luxurious, displaying its opulent grandeur!
The Wuwei Sect truly lives up to its reputation as an ancient and powerful sect! Millions of years ago, it was a dominant force! Unfortunately, later, someone set up a powerful array to divert immortal energy from the Immortal Continent, causing it to converge towards the very center of the continent. As a result, the area where the Wuwei Sect was located became barren. The sect's experts all left, leaving only the ruins of an ancient sect behind!
Lin Caogen entered the main hall! He saw one wall covered with small characters!
Lin Caogen read it carefully and discovered that what was engraved on the wall was the Thunderfire Forging Meridian Heart Sutra!
Lin Caogen studied diligently! He spent a whole day memorizing the scriptures!
It took another three days to study the scriptures and figure out the methods for cultivating the Thunderfire Meridian Forging Heart Sutra!
Lin Caogen sat cross-legged inside the main hall and began his cultivation right there!
Within his body, the lightning and fire transformed into thin, silvery-blue threads, which began to flow along the meridians of the forest roots.
Impurities in the meridians were burned to ashes when they encountered the power of thunder and fire!
However, this process was also extremely painful!
Although Yang Guo directly opened up Lin Caogen's eight extraordinary meridians with his abundant immortal energy, there were still many impurities adhering to the surface of the meridians! In fact, there were still 36,000 tiny meridians in his body that were completely blocked!
Unblocking all these tiny meridians is a delicate task! It would likely take at least a century to succeed!
Some exceptionally talented individuals can achieve rapid success in cultivation within a few decades! Geniuses like Fu Yunxuan and Mu Wanqing!
Lin Caogen is different!
His mind works faster than anyone else's! His brain is like a supercomputer! While others can only focus on opening one meridian, he can simultaneously open a hundred!
Furthermore, he had also cultivated the Divine Soul Scripture! His soul power was stronger than that of ordinary cultivators! Therefore, his cultivation speed in this Qi Condensation stage technique was more than a hundred times faster than that of ordinary people!
If all goes well, Lin Caogen's 36,815 meridians will be fully opened in about a year!
Half a year has passed in the blink of an eye!
Lin Caogen was so immersed in the joy and pain of cultivation that he was completely unaware of the passage of time!
Under his selfless cultivation, all the meridians in his body have been opened! However, more than half of the meridians are still in a semi-open state!
The so-called "semi-open state" refers to the fact that some meridians still have varying degrees of blockage! The flow of vital energy will not be very smooth!
However, as long as Lin Caogen doesn't use any Earth-rank or higher immortal techniques, there shouldn't be too much of a problem!
After six months of cultivation, the immortal energy fluctuations emanating from Lin Caogen's body have become increasingly stronger!
If someone else were standing nearby, they would already be able to determine that Lin Caogen's cultivation level is at the third stage of the Qi Condensation Realm!
