"A thousand-mile embankment was destroyed in an anthill...... Master, I was negligent......"

The old man in white muttered to himself, his eyes were full of chagrin, and after thinking for a moment, he suddenly stood up from the bluestone chair and made a gesture to walk out of the cave.

"Monday! Why are you going? ”

The envy and foolish Qi, who also had an ugly face, saw that the old man in white was moving, and he hurriedly shouted.

Although he and Li Baiyi are in the same boat, but in fact, the two are from the same school, if it is in terms of seniority, Li Baiyi can be regarded as the younger brother of the envy and foolishness.

Coupled with years of getting along, if you say who knows Li Baiyi best in the world, then if you dare to say second, no one dares to say first.

"What are you going to do? Everyone has put the answer on your face, the survival of the human race is in danger, I naturally want to use the vertical and horizontal technique to deduce again, if it is really as Zhang Heng Xiaoyou said, you and I have to go up the mountain to find a way! ”

Li Baiyi's face was pale, and the skill of deduction was his strength, but now he was told that he had made a big mistake, how could this not make him feel anxious and irritable.

"You're going to deduce the development of humanity now? No kidding, if you force the deduction without adequate preparation, you will die of mental exhaustion! ”

The pottery bowl in his hand was smashed to the ground by Envy Yuqi and turned into fragments.

"So what do you say? Before the death of the master, the master specially instructed the two of us to protect the human race thoroughly, and to carry forward the vertical and horizontal lineage, but now? The two of us have lived on this mountain for more than 80 years, not only have we not found the heirs of the same lineage, but we also see that the future of the human race will be ruined in front of us! ”

Li Baiyi's emotions were excited, and the black and cyan trident in his hand seemed to have sensed it, and it actually let out a low buzzing sound.

"It's ...... Sword Intent?! ”

Zhang Heng, who had been sitting at the stone table, didn't get up, nor did he say anything, just squinted his eyes and felt the fluctuations coming from the trident in Li Baiyi's hand.

"Damn, what can I do? Of course, it's slowly trying to figure it out, why are you more anxious than me now, and have you returned everything you learned to Master? ”

Facing Li Baiyi's sword intent, Xian Yuqi also clenched the narrow mouth long knife in his hand, facing the other party's gaze without the slightest fear.

In the process of dialogue, the body of the old man in black also moved, and a more majestic momentum surged out from between his eyebrows, opposing Li Baiyi's sword intent.

"Huh? It wasn't even sword intent...... This envy and fool's qualifications are not as good as Li Baiyi'......"

Feeling the fluctuations from the old man's knife in black, Zhang Heng's brows furrowed slightly.

According to the memory in his mind, the heirs of the two factions, Li Baiyi and Xian Yuqi, have already entered the realm of half-step heavenly beings, otherwise, the lifespan of the two of them will not be far beyond ordinary people, reaching a shocking age of more than 160 years.

It stands to reason that although a martial artist in this realm has not yet reached the realm of controlling the 'will', it should not be difficult to release part of it with the help of the weapon in his hand.

Moreover, Li Baiyi, who was weaker, could release his sword intent, but Xianyu Qi, who was stronger than him, failed to release his sword intent.

This detail obviously doesn't match what Zhang Heng remembers.

However, although there was a question mark hanging on his head that needed to be solved urgently, Zhang Heng still decided to stabilize the situation in front of him first.

It would be terrible if these two old monsters didn't deal with each other and fought again, and then delayed their own affairs.

"Don't worry, two seniors, can you listen to the juniors first?"

Hearing Zhang Heng's persuasion, the smell of gunpowder that originally permeated the air suddenly subsided by half, and the two old men with strange personalities obviously realized that there were still guests

Since he has restrained the momentum on his body.

"Let Zhang Heng Xiaoyou smile, the two of us are like this, because we have accepted the inheritance of [vertical] and [horizontal] respectively, so since we entered the master's door, we have never stopped fighting each other."

Li Baiyi sighed, and although he was anxious, he still opened his mouth to explain to Zhang Heng.

"I understand, the vertical and horizontal veins of Guiguzi are only passed down to two people, one vertical and one horizontal, mutual restraint, each other is the horn, each generation is in the mutual fight between the understanding of the vertical and horizontal artistic conception."

Zhang Heng retold the memories in his mind as if he was endorsing, not because he really listened to the Guiguzi ancestor himself, but because he knew the information obtained through some means.

"I can't imagine that Zhang Heng, a little friend from another world, knows so much about the vertical and horizontal lineage, if it is in normal times, I will definitely have a good exchange with you."

Watching Zhang Heng recount the secrets that only belonged to the vertical and horizontal lineages, Li Baiyi nodded unconsciously.

"But as Xiaoyou said, the survival of the human race is imminent, if I don't deduce it, I'm afraid I will really be unable to return to the sky......"

Speaking of this, Li Baiyi wanted to leave, but Zhang Heng's next words made him completely dispel the idea of re-deduction.

"The human race is indeed on the verge of survival, but it has not yet become a certainty, but if Senior Li insists on deducing, it will completely bury the possibility of human continuation."

"What?!"

"Is that really the case?!"

Li Baiyi and Xian Yuqi spoke at the same time, questioning the authenticity of Zhang Heng's words.

"Yes, I've been to too many worlds, and there are also Terrans there, and there are also existences similar to the two predecessors, but without exception, the Terrans in these worlds were eventually destroyed, and the reason for these is ......"

Speaking of this, Zhang Heng paused, and his peach blossom eyes blinked a few times, as if he was considering the next wording.

In fact, the original meaning of his sentence was that he had been to too many timelines, and in order to change the final direction of human destiny, he had made countless decisions that affected the timeline.

Over the course of time, each different decision forms a different timeline, resulting in very different results.

And the decisions made by Zhang Heng in those timelines did not change the ultimate fate of human destruction.

One of the most important items is to allow Li Baiyi to use the art of vertical and horizontal to deduce the overall situation of mankind on the eve of the outbreak of the catastrophe.

If he did this, no matter how much Zhang Heng changed in the end, he would not be able to reverse the final result of the extinction of the human race.

Seeing Zhang Heng's sudden silence, the two old men thought that the other party had something unspeakable, so their attitude eased and they spoke.

"Xiaoyou's status is special, you don't have to worry about anything, just say it."

Hearing Xian Yuqi's words, Zhang Heng nodded and continued.

"And the key factor that created the extinction of human beings in these worlds lies in the two predecessors."

"If Li Baiyi's predecessors insist on deducing the vertical and horizontal technique now, everything that the younger generations have done will be wasted, and the future of mankind will eventually go to darkness and never recover."

Zhang Heng's words obviously startled Li Baiyi, and at this time, the trident in the hands of the old man in white no longer hummed, and he was a little calmer.

"Monday he ...... Does it really matter? ”

Although Xian Yuqi believed most of it, the doubt in his eyes still did not completely dissipate, and he glanced at his junior brother who had calmed down, and asked.

"A Thousand Miles of Embankment."

Zhang Heng didn't say anything else, just put four

The words came out of his mouth faintly.

These four words are like morning bells and dusk drums, completely sweeping away the impulses in Li Baiyi's mind and returning to his senses.

"I was reckless before, Xiaoyou, you can continue to talk about it, is there a solution to the danger of extinction of this human lineage?"

2k

Although Li Baiyi is already an old man who is as old as one hundred and sixty-six years old, he has no shelf as an elder, and if he is wrong, he is wrong, and he does not feel taboo about a junior pointing out his mistakes.

"The solution to the danger of extinction...... Won't I come then......"

A helpless smile appeared on Zhang Heng's face, he traveled through so many timelines, didn't he end up rewriting the fate of the human race?

Although the two old men still had doubts, they still regained their patience, sat back at the bluestone table, and listened to Zhang Heng continue.

Among them, Li Baiyi took the teapot on the table again, and prepared to pour another cup into the porcelain cup in front of him.

Seeing the actions of the old man in white, Zhang Heng raised his eyebrows, and decided to use this water as a starting point to start his own story.

"Senior, do you know why I didn't drink this glass of water you gave me."

Facing Zhang Heng's clear gaze, Li Baiyi stopped pouring water in his hand with some hesitation.

"You shouldn't be afraid that I poisoned you in the water, the old man acts above board, even if he wants to calculate you, he won't use this kind of indiscriminate means."

Li Baiyi said with a straight face, although the sect he inherited was not very famous, but after all, it was not those evil ways of the outer sect, and although he was wary of Zhang Heng in his heart, he did not have the slightest intention of hurting the other party.

At best, it is just a matter of guarding against others.

"Hehe, this water is indeed poisonous, but it wasn't given to me by your predecessors."

The old man in white thought that Zhang Heng would wave his hand to explain, but he didn't expect the other party to nod after listening to his words, and immediately affirmed the statement that the water was poisonous.

"How can this water be poisonous, if it is, wouldn't he have been poisoned to death by Monday?"

Envy Yuqi, who has a fierce face, is a straight man who can't bear it, and when he heard Zhang Heng say this, he immediately said in his lion-like voice.

"Please don't worry, the seven seniors of the Envy Fool, listen to me slowly."

Zhang Heng still maintained a smile on his face and patiently explained.

"The poison in this water is naturally not from the two seniors, and the cup of poisonous water that Li Baiyi's predecessors drank before will not be a big problem for the time being."

"The poison in this cup comes from outside the sky, and if ordinary people are contaminated, they will be infected with an incurable disease."

"This disease does not kill people, on the contrary, it will enhance the functions of the human body to a certain extent."

"But at the same time, it will also make people completely lose their minds, become a kind of blood-drinking and flesh-eating monster, and spread it by biting and scratching, so as to achieve the purpose of spreading among the human race."

Listening to Zhang Heng's explanation, two words popped out of Xian Yuqi's mouth.

"The plague?"

"Almost, closely."

Zhang Heng nodded, affirming the understanding of Envy Yuqi.

"That's what caused the extinction of the Terran line?"

Li Baiyi also heard the point and interjected.

"No, this plague is not the cause of the extinction of the human race, but it may become an opportunity to change the fate of the human race!"

The young man leaned back slightly, and a mysterious smile appeared on his face......
