"Boom"!

The black iron needle on the stone disk trembled slightly, and then a viper-like black lightning burst out of it, striking Han Li's fingertips at once.

A sharp pain went straight to his soul, and he couldn't help but gasp in pain, his eyebrows twitched, and he retracted his hand.

Hearing the movement inside, the remnant soul of the old Dao, who had recovered some strength in the soul cultivation furnace, couldn't help but let out a burst of gloating quacking laughter.

As a result, before he could finish laughing, the soul cultivation furnace was swept by a blue light and pulled into the hall.

"Oh, I said you little ......" The golden light on the ground shrouded again, and Lao Dao immediately let out a miserable cry.

With a casual swipe of Han Li's hand, a circular arc of light immediately enveloped it, enveloping the entire Soul Cultivation Furnace before Lao Dao's seeping screams subsided.

"Little ...... Boy, you are ruthless, I want to ...... the Taoist master back then" Lao Dao looked miserable and said quietly.

"Tell me, what's going on here?" Han Li raised his eyebrows at the sundial on the stone platform with the incense burner in his hand, interrupting his old words.

"How does Dao Ye know...... Ay...... If you have something to say, don't ......"

Before he could finish speaking, he saw Han Li raise his hand to remove that layer of light arc, and immediately begged for mercy.

“...... This is the Taiyin Sundial, and it is also the core of the secret realm here, and it is only possible to leave this secret realm if it is completely destroyed. Lao Dao said weakly.

"Just destroy it?" Han Li said as he heard this, a hint of eagerness flashed in his eyes.

"Dao Ye advises you, with your kid's current strength, just think about shaking this thing, it is simply an egg to hit the stone, once the yin thunder released by it is counterattacked, be careful to end up scattered. Lao Dao suddenly sneered and said, his tone was very solemn.

"You've said before that if you master the laws of time or space, it will be of great benefit to cracking the core of the secret realm, right?" Han Li asked with a deep groan.

"That's nature, you know, the law of time and space is one of the three supreme laws of this realm, how can it be compared with the ordinary law! The law of space is the original basis for the existence of all spatial barriers and prohibitions, and it is to trace back to the origin to crack it. As for the law of time, it's because this Taiyin Sundial is a half-immortal artifact that contains the power of time......" Lao Dao Kankan explained.

Hearing this, Han Li's brows furrowed suddenly.

He tried it just now, but he didn't detect the power of the law of time from it.

"Senior, we might as well talk about it openly. I happen to be cultivating the law of time, why didn't I find any power of time on this sundial when I just investigated?" Han Li interrupted the old Dao's rambling and asked in a deep voice.

"What, you kid is not joking, are you, you really cultivate the law of time? Don't bluff Dao Master me, tell me, have you ever condensed the silk of time? How many are there?"

"Senior, please answer my question first. Han Li said with an expressionless face.

"Okay, Dao Ye will believe you once! But then again, Dao Ye has long seen that you kid has a strange root and an extraordinary face, and he must be very human...... As for not being able to find the strangeness on the sundial, it seems that you don't have more than five threads of time, otherwise you wouldn't be able to find them. Lao Dao smiled, first rambling on and on, and finally said.

"Are you saying that I don't have enough grasp of the law of time?" Han Li said with a raised frown when he heard this.

"Let's put it this way, even if you are cultivating the Law of Time Technique, if you want to destroy the core here, you must cultivate at least the middle stage of the Golden Immortal and master at least ...... It takes at least six threads of the law of time to make it possible. Lao Dao continued.

"Golden Immortal Mid-Stage...... Don't hide it from my predecessors, my cultivation in the early stage of the Golden Immortal has not yet been completely stabilized, and if I want to cultivate to the middle stage of the Golden Immortal, it is impossible without ten thousand years. Han Li frowned.

"Good boy, your tone is really not small, you want to advance to the middle stage in 10,000 years? Lao Dao glared and sneered.

Hearing this, Han Li couldn't help but fall silent, Lao Dao's words were not alarmist, without the assistance of the Golden Immortal Combined Pill, he really didn't have the confidence to advance to the middle stage within tens of thousands of years.

"But don't be discouraged, boy. Speaking of which, it can be regarded as a good fate for you kid, you met Dao Ye and me, Dao Ye I have another way that may be able to help you, but I don't know, do you kid dare to use it?" Old Dao glanced at Han Li up and down, and said in a slightly provocative tone.

"What's the method?" Han Li asked, looking at the wisp of remnant soul.

"The difficulty of advancing to the middle stage of the Golden Immortal lies in the opening of the twenty-four immortal apertures. The difficulty of these twenty-four tricks is far from being comparable to the thirty-six tricks in the True Immortal Realm, and Dao Master I have a method of attracting evil qi to impact the immortal aperture, which can greatly shorten your cultivation time. Lao Dao shook his head and said.

"Evil Qi, this kind of partial path, I'm afraid that after using it, there will be endless troubles, right?" Han Li frowned and said with a sneer.

"Who says it's not? Otherwise, why should I ask you if you dare first? You just listen to Dao Ye and I finish speaking, as for whether you want to cultivate or not, that's your kid's own business. In fact, evil energy, like mana, exists in your body, but under normal circumstances, it never manifests. If you talk about the aftermath, it is that within the immortal aperture you have opened, there will be evil qi remaining, as for the specific impact, it varies from person to person, and the old way cannot be said thoroughly. The old man sighed and explained.

After finishing speaking, Lao Dao suddenly remembered something again, and hurriedly said: "By the way, there is another drawback, that is, this method is the same as alchemy, which is not tolerated by the heavenly court. Once discovered, it is likely to attract an inspector immortal envoy, but it is very troublesome. ”

Hearing this, Han Li habitually rubbed his nose and fell into deep thought.

This method sounds so evil, the disadvantages must be more than what this old Taoist said, as for being disallowed by the heavenly court, he doesn't care, anyway, he has already cultivated the alchemy technique, and it is not allowed to cultivate the same, and there is no difference between the two or not.

"If you use this path to pass through the immortal aperture, how much time can you shorten?" After a long moment, Han Li raised his head and asked.

"Well, it also varies from person to person, and the evil spirit is strong...... In other words, if you kill more immortals, it is naturally easy to penetrate the immortal aperture. As for those who are sparse, they are naturally slow. However, according to Daoye, from my point of view, your appearance should not be much thicker, and it would be good to double the speed of death. But don't underestimate this speed, even if it's a top-grade elixir, it may not have this effect!" Old Dao glanced at Han Li and said with a chuckle.

"Is the evil aura thick, how can I check it?" Han Li asked ignoring the old words.

"This is easy to do, Dao Ye, I will teach you a trick of evil qi manifestation, listen carefully. With that, Lao Dao recited a strange mantra.

Han Li followed the instructions of the old Dao, clasped out a strange mantra with both hands, and began to recite the mantra:

"One breath divides yin and yang, and there are three evils in Xuanyin...... Fierce gathers springs, and blood is stationed in the inner gate...... Evil starts from the heavenly spirit and manifests like a twilight spirit!"

"Present"

Han Li gave the order and stomped on the ground with one foot, and the entire hall shook with it.

I saw that the black gas in the shape of smoke rolled up from above his head, spreading like a black cloud, covering the entire hall dome, and his body was also surrounded by wisps of black smoke that was as black as ink and condensed like substance.

These black gases continued to emerge from its body, intertwining and tumbling, thick as ink.

Han Li's entire body was full of aura, and his aura was surging to the sky.

The remnant soul of the old Dao stayed in the incense burner, looking at Han Li who looked like a god in front of him, his mouth was wide open, and he couldn't close it for a long time, if it weren't for the fact that he had no entity, he was afraid that his jaw would have dropped off at this moment.

"This, this...... It's spectacular, it's spectacular...... How many people have you killed since you kid cultivated so far......" he muttered to himself.

Han Li didn't feel anything unusual, he just felt that after these black mist were revealed, he felt a lot more relaxed, but at the same time, there was also a trace of indescribable anger in his heart.

"How's my evil spirit?" Han Li's mind turned as he suppressed the strange state in his heart and looked at Lao Dao and asked.

"The evil qi is as rich and rich as you, Lao Dao has seen a lot, but most of the bloody qi is rich and shows a dark red color, but you are very different, the black is so pure, the children can be taught, the children are really teachable. If you want to cultivate my method, the disadvantages can be reduced by at least more than half. The old man praised.

When Han Li heard this, he didn't feel very happy, as soon as he collected the magic trick in his hand, the billowing black qi that was still being released from the outside suddenly converged back into his body and disappeared.

"Why are you in a hurry to take it back? It hasn't been completely released yet...... Lao Dao complained a little.

"Teach me your exercises. Han Li spoke.

"Have you decided to use it?" have you figured it out, hehe...... "Old Dao asked with a smile.

Han Li didn't answer, he didn't decide to use this method immediately, he just thought about getting the exercise in his hands first, using it for specific purposes or not, and then talking about it depending on his cultivation status.

After obtaining the evil qi gong method called "Xuan Sha Twilight Linggong" from Lao Dao, he sent his remnant soul back to the underground palace hall where he was originally located.

In order to help him stabilize his soul, he temporarily placed the soul cultivation furnace there.

Although I don't know how much of the truth or falsity of this old Dao's words is now, this person must know a lot about the Immortal Palace, and it is expected that a wisp of remnant soul will not be able to pose any threat to him, so it is better to stay first.

After doing all this, Han Li came to another dark room of the underground palace with a large area, and after closing the stone door, he began to take out a set of forbidden magic circles and busily set them up.
