On that planet with extremely low temperatures and uneven potholes, Sun Xiaoxuan sat on the ground with a calm face, and Li Peicheng was also sitting calmly when she was only ten miles away. But this time, his eyes flashed with anticipation that was different from helping other people survive the catastrophe in the past.

I don't know if there will be a breakthrough this time? Li Peicheng's longing thoughts flashed through his mind.

The clouds in the sky are getting lower and lower, because of the double cultivation of husband and wife, because the two have been completely integrated, when Li Peicheng calmed down and focused all his attention on Sun Xiaoxuan, although it was ten miles apart, Li Peicheng felt the changes in the body of the robber more clearly than ever before, and this change even produced the illusion that it was a change in his own body when Li Peicheng forgot himself.

The obscure release and retraction of the true element in the body was magnified countless times in Li Peicheng's senses, beating like a human pulse, and the frequency of fluctuations was changing at an untraceable speed, and at the same time it became more and more obscure. The calamity clouds in the sky seemed to be closely related to the changes in the true element, and as the frequency of the true element's fluctuations increased, it became more and more intense, and it seemed that it was about to explode at any time.

Suddenly, Li Peicheng felt that the fluctuation of Sun Xiaoxuan's true yuan mana was maintained at a relatively stable frequency, and at this time, the heavenly thunder finally reached the extreme, and the thunder thunder cracked the cloud with a bang and slashed towards Sun Xiaoxuan.

The huge sound of the thunderbolt falling down seemed to be in Li Peicheng's mind, making him shake, the mystery he had explored for a long time, he finally found the mystery in it, the mystery of the heavenly tribulation.

Li Peicheng couldn't restrain a look of ecstasy on his face, but he immediately stabilized the ecstasy in his heart and restored his state of mind to the realm of Gujing Bubo, which was just a conjecture.

In scientific research, conjecture is a breakthrough, but conjecture needs to go through constant verification before it can finally become the truth. He has only taken a crucial step now and has not yet reached the end of the truth.

Li Peicheng carefully experienced that because the changes in the celestial phenomena were extremely turbulent at this time, Li Peicheng almost didn't need to pay much attention to detect the changes in the energy of the surrounding space, but the changes in Sun Xiaoxuan's body still required him to observe them with full attention.

The beat is almost unanimous, as if the beating of the heart is as coordinated as the beating of the pulse. This is the connection between Sun Xiaoxuan and heaven and earth that Li Peicheng feels.

The thunderbolts slashed down one after another, and although Colorful Luopa was a defensive magic weapon that was extremely close to the immortal weapon level, it still began to become a little overwhelmed. Sun Xiaoxuan hurriedly put away the Colorful Luopa and sacrificed the immortal-level magic weapon Blue Flame Yin Ring.

Every time a thunderbolt strikes, the blue flame yin ring shoots out an incomparably brilliant blue flame into the sky like an anti-aircraft cannon.

The blue flame is yin to cold, and it faintly has the effect of restraining the yang and heat of the thunder, so that Sun Xiaoxuan supported all the way to the last thunder after taking a pill of the Replenishing Yuan Pill, and did not take the Huiling Pill specially prepared for injury.

When the thunderstorm was carried out to the last three or four paths, Li Peicheng suddenly felt that the frequency of Sun Xiaoxuan's True Yuan mana fluctuations, which had been smooth, had changed, and it had risen all the way. By the time the best tribulation thunder fell, the true element mana fluctuations had become more obvious than before the tribulation. Of course, this is more obvious than Li Peicheng's feelings, in fact, if it weren't for Li Peicheng's surprisingly keen senses, and the relationship with Sun Xiaoxuan as husband and wife, this change would have been missed if he was not careful.

In fact, whether it was before and after the Wuji Demon Lord or Cang Hao and others, Li Peicheng also had a little feeling, but it was too small to attract his attention, until now because of Sun Xiaoxuan's relationship, this relationship has been magnified many times, coupled with the previous speculation, he paid infinite attention to it, and at the same time, it also confirmed his previous conjecture from a certain angle.

The clouds dissipated, and peace returned to heaven and earth. Sun Xiaoxuan took out a piece of Yuan Ling Stone and quietly breathed it, trying to restore the true Yuan mana, and a satisfied smile appeared on his beautiful face. At this time, Li Peicheng stood up early, walking back and forth in place with an excited and happy face, muttering words in his mouth, and his fingers kept comparing and buttoning the board, obviously calculating and deducing something in his heart, and unconsciously used his hands and mouths and brains.

Sun Xiaoxuan finally finished pranayama, although only Li Peicheng was present, she still casually set up a mist array, took a shower in it, changed into refreshing clothes, and then withdrew the mist array.

As soon as Sun Xiaoxuan withdrew from the mist array, he saw Li Peicheng punch his palm and said, "This must be the case." ”

Li Peicheng has been studying and exploring the secret of the Heavenly Tribulation, as his wife, Sun Xiaoxuan still heard a little, seeing this, he immediately stepped forward and said with a happy face: "What must be like this?

Li Peicheng was about to answer, but when he looked up, he obediently, Sun Xiaoxuan, who has now survived the catastrophe, is even more moving, especially the pair of charming but heroic beautiful eyes are now more seductive, which makes Li Peicheng a little stunned.

"Hey, brother, what do people ask you about?" Sun Xiaoxuanqiao's face flushed slightly, half angry and half angry.

Li Peicheng came back to his senses, smiled, took Sun Xiaoxuan's hand, and said, "While walking, talk at the same time." ”

The two drove an auspicious cloud and flew in the vast expanse without seeing a single person, only seeing the rocks flying in the space.

"What, the principle of resonance? You said that the catastrophe was caused by resonance?" Sun Xiaoxuan widened her big eyes in disbelief, exclaimed in surprise, and then she immediately said: "This is impossible, absolutely impossible!"

Sun Xiaoxuan is also a college student in science and engineering, so he naturally understands what the principle of resonance is. It is a phenomenon that is ubiquitous in nature, the resonance of sound, the resonance of mechanics, the resonance of electricity, the resonance of the microcosm...... It can be said that resonance is now ubiquitous, and it is just that no one cares about discernment. In fact, it is not an exaggeration to say that it is as ubiquitous as gravity exists in this world.

But to say that this mysterious and unpredictable Heavenly Tribulation, which made all cultivators fear and long, was actually caused by resonance, Sun Xiaoxuan couldn't accept this statement anyway.

In fact, don't talk about Sun Xiaoxuan, Li Peicheng is not, otherwise he has observed so many people crossing the heavenly tribulation, how could he suddenly come to his senses today, of course, because of Sun Xiaoxuan, there is no factor that he did not think about in this regard.

Li Peicheng nodded solemnly and said, "Let's not say whether this heavenly tribulation is caused by resonance. In fact, resonance is really a very magical kind of natural imagination. I remember that an American inventor once said that if he was given a resonator, he could split the earth in two! Although he did not do this, he came to Wall Street, climbed up an unfinished steel frame building, took out a small object from his coat pocket, clamped it to one of the steel beams, and pressed a small button on it. After a few minutes, the steel beam could be felt shaking. Slowly, the intensity of the tremors began to increase, extending throughout the building. Eventually, the entire steel structure began to creak and sway. Seeing that things were getting bigger and bigger, he thought it was time for this prank to end, so he took the little item back and slipped quietly through an underground passage. ”

For these scientific stories, Sun Xiaoxuan knows far less than Li Peicheng, and she listens to them a little fascinatingly.

Li Peicheng paused, his eyes flashed with a strange light, and said: "In fact, many scientists say that resonance produces the universe and all things in the world, and there is no world without resonance. They believe that the universe came into being after a violent Big Bang, and that one of the big bangs was caused by resonance. When the universe is still at a chaotic singularity, oscillations begin to occur inside. In the beginning, the oscillations were very weak. Gradually, the frequency of the oscillations became higher and stronger, causing resonance. Finally, under the combined effect of resonance and expansion, it led to an earth-shattering bang, and the universe expanded and expanded sharply in an instant, and then the moon and stars were produced. It's a pity that we can't verify this. ”

In fact, the emergence of the macrocosm and the microcosm of the material world is also inseparable from resonance. For example, the atomic absorption emission and characteristic spectral lines that we learned in college all involve the principle of resonance. Even we call the characteristic spectral lines of atoms resonance lines. Not only these, but also the natural frequencies of breathing, heartbeat, and blood circulation, as well as the brain waves generated by the human brain during thinking activities, also resonate......"

"But how can the Heavenly Tribulation have anything to do with resonance? This is incredible!" Sun Xiaoxuan didn't insist on her own opinion as before, but judging from her expression, she still didn't agree with Li Peicheng's point of view.

It is also mysterious, and how can the Heavenly Dao, which is full of mysteries, be related to those basic scientific principles.

Li Peicheng looked at Sun Xiaoxuan with some seriousness and criticized: "How many times have I told you, no matter how miraculous it is, there must be some kind of essential law behind it, and it will never be created out of nothing, and don't blame it on the invisible and untouchable Heavenly Dao." Just like many people blame their own fate for what happened to them, in fact, it is actually his own problem in the end. ”

Sun Xiaoxuan rarely saw Li Peicheng reprimanding her, and couldn't help but bow his head a little uncomfortably, Li Peicheng saw this and knew that he was a little serious, so he gently touched Sun Xiaoxuan's black and soft hair with his hand, sighed and said: "Actually, I have been misled by this concept many times, and there are actually preconceived reasons for this catastrophe, otherwise I should have been able to see the clues earlier." ”

Sun Xiaoxuan felt Li Peicheng's gentleness, and also knew that Li Peicheng was for her good, so he gradually regained a smile on his face, raised his head, looked at Li Peicheng and said, "Then tell me why the catastrophe is caused by resonance." ”

Li Peicheng smiled, considered the words slightly, and said: "Actually, the person who crossed the tribulation is Zhenyuan, and the heavenly tribulation is the resonant body that is caused by the reaction. I have carefully observed just now, before your tribulation, the true yuan mana emitted a continuous change of frequency, and a certain energy in heaven and earth gradually changed and converged because of this frequency, and when the frequency reached a certain point, the heavenly tribulation finally came. During the entire process of responding to the tribulation, the frequency on your body was surprisingly similar to the frequency of the heaven and earth that produced the tribulation thunder, until the end of the tribulation, because of the breakthrough of your realm cultivation, the frequency of the transmission of the true yuan mana finally changed a lot from before, and if you didn't attract that energy, the heavenly tribulation was dispersed. ”

Sun Xiaoxuan began to fall into deep thought, but her eyes were still indescribably confused, after all, she had not personally experienced all these changes, nor did she have such a keen insight as Li Peicheng, it was difficult to feel the shock of the truth between the lines of Li Peicheng's words.

Seeing this, Li Peicheng continued: "You should know that there are two major factors related to resonance, one is frequency and the other is intensity. ”

Sun Xiaoxuan nodded, her eyes suddenly lit up, as if she had thought of something.

Li Peicheng continued: "To cause resonance, frequency is the most critical, and without a common frequency, no matter how powerful it is, it will not cause resonance. When the cultivation realm of the cultivator continues to improve, the fluctuation frequency of the true yuan mana in his body begins to get closer and closer to a certain kind of energy that can produce thunder in the heaven and earth, and when it is close to a certain level, the heavenly tribulation is also formed. In the process of crossing the Heavenly Tribulation, your state of mind has been tempered, your true yuan mana, and your physical body have been tempered and beaten to a certain extent, and finally the realm has been broken through, forming different fluctuation frequencies, which will no longer cause the resonance of the kind of energy in heaven and earth, and the Heavenly Tribulation will pass. ”

"Then why do cultivators have three heavenly tribulations?" Sun Xiaoxuan then asked.

"The inherent frequency of a substance is more than one, just like an atom it has countless resonance lines, nothing more than different strengths and weaknesses, you have used the original absorption spectrometer with me before, you should know that to analyze an element, we can choose several spectral lines, these spectral lines are the strongest spectral lines of the element's absorption, in fact, to put it bluntly, it is the spectral line with the best resonance effect. A cultivator has three heavenly tribulations, which is nothing more than that before he reaches the Mahayana period, there will be three true yuan mana fluctuations with the frequency of fluctuations that are just the same as or extremely close to the fluctuation frequency of the energy between heaven and earth. And the resonance effect of the back is better than the front one, so the power is more violent. Li Peicheng replied.

Sun Xiaoxuan was finally a little relieved, stared at Li Peicheng with admiration, and said mischievously: "I really want to pry my brother's head open to see what is different inside." ”

Because he had roughly found the reason for the formation of the Heavenly Tribulation, Li Peicheng was in a good mood, gently scratched Sun Xiaoxuan's small and straight nose, and laughed: "It's nothing more than a brain!"

"Phew!Phew!" Sun Xiaoxuan took several sips, glanced at Li Peicheng, and said angrily: "Brother, it's disgusting!"

Li Peicheng laughed smugly again, thinking that as long as this conjecture was not wrong, once he had studied a solution by himself, he could let go of his courage to cultivate.

At that time, Li Peicheng's eyes couldn't help but flash a cold light.

Sun Xiaoxuan suddenly felt a chill all over her body, glanced at Li Peicheng, and said, "Brother, what are you thinking?"

Li Peicheng didn't want Sun Xiaoxuan to worry about the Lotus Sect for the time being, so he said casually: "It's nothing, I'm just thinking about how to solve the problem of the Heavenly Tribulation." ”

Sun Xiaoxuan didn't think deeply, oh, and then asked, "Do you have any eyebrows?"

"There is no eyebrow for the time being, but if the Heavenly Tribulation is really caused by resonance, there are no more than two methods, one is to suppress the outward fluctuation of the true element's mana, that is, to forcibly suppress the fluctuation intensity, the intensity is too small, although it will also cause a little reaction, but it will definitely not attract the Heavenly Tribulation. The second method is to change the fluctuation frequency of the true element mana, as long as the fluctuation frequency changes, it will naturally not attract the Heavenly Tribulation. Li Peicheng pondered for a moment and replied.

"Listening to my brother say this, I remembered that before the Heavenly Tribulation was coming, I always felt that the surrounding energy fluctuations were abnormal, so I naturally thought that my cultivation was improving and expanding to cause the Heavenly Tribulation, so I reflexively tried my best to compress the true element in my body, and sure enough, that feeling was reduced a lot, until I could no longer compress and converge, and then I knew that the Heavenly Tribulation was inevitable. Now after my brother said this, after thinking about it carefully, it really responded to my brother's first statement, which is equivalent to forcibly weakening the intensity of fluctuations, so that feeling is reduced. Sun Xiaoxuan said with ripples in her eyes.

When Li Peicheng heard this, he couldn't help but be happy again. He is still in the late stage of integration, and he can't understand Sun Xiaoxuan's feelings, and now listening to her say this is tantamount to further confirming his conjecture.

Thinking about it carefully, the degree of the true element in his body is actually almost equivalent to the late stage of the tribulation, but he has not sensed the heavenly tribulation for a long time, doesn't it just mean that because of the realm, the frequency of the fluctuation of the true yuan's mana is still in the late stage of the merger?

"Haha, it seems that the cause of the Heavenly Tribulation is this resonance. Now that I know the essential reason and prescribe the right medicine, I think I can always find a suitable method. As long as we can find a way to postpone the date of the tribulation, even if the external conditions are worse, the hope of the success of the tribulation of our sect will be greatly increased. Li Peicheng said with a smile on his face.

Sun Xiaoxuan's heart trembled, her eyes stared at her beloved man with some obsession, and she felt infinite pride in her heart.

Dividing line-

Outside the Valley of All Souls, a golden light streaked across the sky, and then landed at the entrance of the Valley of All Souls.

The Lotus Sect disciples guarding the valley felt that their eyes were blooming, and there was a handsome man dressed in golden light in front of them.

The man's eyes looked around him with cold pride, and as his gaze swept over them, they felt their blood freeze, and they couldn't restrain the urge to prostrate themselves.

A grim smile tugged at the corner of the handsome man's mouth, and he walked towards the valley with a step, as if he didn't see the two Merge Stage disciples guarding the valley at all.

A cold mountain breeze blew, and the two disciples guarding the valley suddenly came to their senses, looked at each other in horror, and then shouted angrily at the handsome man who had already stepped on the valley and was a hundred meters away from them, and shouted: "What kind of madman, dare to trespass on my sect's important land!"

As he spoke, his figure flashed, one after the other, one left and one right flew towards the handsome man, and at the same time raised his knife palm and slashed towards the handsome man in the air.

The handsome man immediately felt two powerful murderous auras, and with the surging and fierce invisible palm knife, they broke through the air.

The corners of the handsome man's mouth hooked up a sneer of disdain, and a cold and cold glint flashed in his eyes, and he flicked the wide sleeves of Jin Guangxian's coat back.

The wind rose on the flat ground, and the wind was cold and fierce.

Smack!

The two men who shot were immediately swept into the air without resistance like two autumn leaves in the wind, and then fell down fiercely.

"Hmph, it's not a long-sighted thing! If it weren't for your loyalty, this ancestor would have abolished you!" the handsome man muttered to himself expressionlessly, his voice cold to the heart and lungs, and he walked unhurriedly towards the magnificent hall that floated out of thin air in the valley at a height of a thousand meters.

The Valley of Ten Thousand Souls is the stronghold of the Lotus Sect, not only heavily guarded, but also guarded by the elite of the elite. It is not difficult to see from the fact that there are only two people guarding the mountain gate who have a monk in the merger period.

This handsome man stepped into the Lotus Sect with such a big grin, and shot to hurt people, and there were already figures flying around him, and in the blink of an eye, he was surrounded by him.

"He Fang Demon ......" A purple-clothed envoy with a withered face and a particularly gloomy appearance pointed at a handsome man, who had just scolded halfway through his words, and was forced back by the handsome man's electric gaze.

With a pop, he knelt down, trembling all over.

"I don't know if the ancestor has arrived, the disciple should die, the disciple should die!" knocked his head again and again.

The rest of the people were about to sacrifice the magic weapon to kill this madman who dared to trespass into the Valley of Ten Thousand Souls, when they suddenly saw the purple-clothed messenger kneeling and bowing, and their hearts were shocked, and when their eyes swept over the handsome man's handsome almost bewitching face, their bodies were suddenly shocked, and their minds couldn't help but think of the portrait of the Liedai Sect Master who was enshrined in the main hall, wasn't this man the Lotus Ancestor who founded the Lotus Sect?

Everyone didn't have time to think about how this Lotus Ancestor didn't enjoy the blessings of the fairy world, but returned to the world, and they all knelt on the ground with a puff and shouted to the Ancestor.

The handsome man looked around at the black and oppressive group of cultists, looked up to the sky and let out a long laugh, indescribable arrogance, laughter echoed in the valley, startling countless birds.

"Okay, finally there is still you, an unsuccessful disciple, who remembers this ancestor!" Lotus Ancestor's cold expression warmed a little, and his hand beckoned to the purple-clothed envoy with a withered face, and said, "You get up and come to this ancestor." ”

The purple-clothed envoy resisted the fear and surprise in his heart, stood up respectfully, stood by his side with his hands tied, and said, "Disciple Sun is waiting for the orders of the old ancestor. ”

Lotus Ancestor nodded with satisfaction and said, "You go and call the current sect leader to come and see this Ancestor." ”

The purple-clothed messenger hurriedly bowed down and retreated cautiously, until a certain distance was reached, and then he quickly flew away.

After the purple-clothed envoy left, the Lotus Ancestor waved his sleeve robe and said coldly, "Get up!"

At this time, no one dared to stop them, and they all trembled and avoided a wide passage.
