Zheng Qian's brows furrowed slightly, if he said so, this Great Dao True Scripture is definitely not an ordinary thing.

While talking to the big black dog, he went to carefully communicate with the Great Dao Sutra, but the latter did not have the slightest reaction at all, no matter any urging and communication from Zheng Gan, this Great Dao Sutra seemed to not belong to him, just lying quietly in his sea of consciousness, exuding a faint essence, like everyone's breathing.

"Hey, there's something wrong with this Great Dao Sutra!"

Zheng Qian told the big black dog about his doubts.

The big black dog also frowned, and muttered: "No, as far as I know, this foolish tea head is also treasureless, since this map has even been signed by him, it is enough to see how much he attaches importance to this Great Dao Sutra, and now, this Great Dao Sutra has indeed disappeared from the stone wall, and successfully entered your body, it stands to reason that there should be no reaction at all!"

Zheng Qian tried again according to the methods taught by the big black dog, but the Great Dao True Scripture was still like an uncle, not moving like a bell.

In the end, Zheng Qian had to give up.

"Hey, I really thought I had picked up a treasure, but I never thought that it was such a chicken rib!" Zheng Qian's face was full of helplessness.

The big black dog also frowned, and he didn't know what he was thinking.

At this moment, suddenly, in the mountains and forests in front of him, a huge thunderbolt power impact exploded violently.

The big black dog moved its nose, and its face changed greatly, "It turned out to be the breath of the Ten Thousand Tribulation God Thunder......

Zheng Qian's expression also changed, "It's not good, it's that canyon, how can I forget this stubble......"

As he spoke, Zheng Qian turned around and ran, he still had to figure out the matter of the minotaur.

The big black dog also followed, and along the way, Zheng Qian also told the big black dog all the news of Xiliang Mansion and Yanqingmen in Zhongzhou City.

"Damn, the dog master has already seen it, this grandson didn't have any good intentions, and said to save his daughter, if it was really his daughter who had an accident, he himself could really sit idly by and watch it?" the big black dog scolded.

Zheng Qian also smiled bitterly, "What can I do? One is willing to fight and the other is willing to suffer, and now among the one hundred people who have entered here on the list, nominally to save the city lord's daughter, but in fact, almost all of them are here for the secret of the Minotaur, don't they know Yan Qingmen's lies? It's just that they have to use Yan Qingmen's hand to enter this 100,000 mountain, why not?"

"By the way, I also got a little bit of news...... the big black dog said suddenly, "If my guess is correct, then the Minotaur should have something to do with the Great Dao Sutra you just enlightened!"

"What?"

Zheng Qian, who was running wildly in front of him, suddenly braked suddenly, and looked at the big black dog with a strange face, "What did you say?"

It's no wonder that Zheng Qian is so out of shape, he knows the true origin of this Great Dao Sutra, Lao Tzu rode a green ox west out of Hangu Pass, could it be that this bull-headed man is Lao Tzu's mount Qingniu? After he left Hangu Pass, he did not go to other places, but returned to the evil world?

As soon as this conjecture came out, Zheng Qian's heart beat wildly, and he himself couldn't believe that all this was true.

The big black dog didn't notice the change in Zheng Gan's face, its face became solemn, and it paused, and said: "You should remember under that lake, right? When I went first, I found several stone tablets at the bottom of the lake, most of the stone tablets were damaged, only one can be identified, and those stone tablets are all stone tablets of different ages, and the stone tablets that can be identified are considered to be the most recent, and they are only about 2,500 years ago......

"More than 2,500 years!"

Zheng Qian's heart was shocked, "According to the time calculation, the time when Lao Tzu rode a green ox and sent a letter to Guguan in the west was probably exactly two thousand five hundred years ago......."

"What is written on that stele?" asked Zheng Qian eagerly.

The big black dog shook his head, "I didn't write anything......"

Seeing Zheng Gan's disappointed face, the big black dog followed again: "Although I didn't write it, but there was a painting on it, and that painting, for some reason, the upper part seemed to have been worn off by something, but the lower part was clearly visible!"

"What?" Zheng Qian's heart had already risen to his throat, and he was eager to know the news.

The big black dog glanced at Zheng Qian, "What are you anxious about, isn't this about to be said!"

"In the lower part of the stele, a young man is depicted, to be precise, a half-human and half-oxen, in that picture, the young man stands upright, holding a knife in his front hooves, and is cutting his own flesh and skin, and under the flesh, there is a pair ......of human legs exposed," the big black dog said slowly.

Zheng Qian's heart sank, "Could it be that what is recorded on this painting is the origin of this minotaur?"

His face was strange, if this minotaur was really Lao Tzu's mount, Qingniu, then it was certain that he had definitely returned here after leaving Hangu Pass, but he was able to avoid the detection of the gods of heaven and come here without a sound, so why did he throw his mount down? And where did he go? What happened to him back then? What was the picture of the destruction of the upper part of the slightly clear stone tablet at the end?

Zheng Qian's mind suddenly had a lot of doubts.

He also wants to find Lao Tzu, perhaps, if he really finds Lao Tzu, he will be able to find a way to return to the earth, and now Huang Ning has also found it, and after he gets the Tianyan Divine Technique, he will have a way to save Huang Ning, and then he will go back.

Although they were puzzled in their hearts, the speed under their feet did not decrease, and in a short time they reached the place where they had reached the canyon before.

Zheng Qian didn't show up easily, at this moment, he happened to see Dugu Mo fighting with several men, and began to dissolve the Ten Thousand Tribulations Divine Thunder, and in front of that, there were fifty people who were firmly bound, and then their life essence blood was extracted, when Zheng Qian arrived, their life essence blood had already been absorbed, and they were weak to return to the sky.

He recognized it, one of the men standing with Dugu Mo was named He Zhu, and the other was named Yuan Ruihe, who were the third and fourth people on the list that day.

"I really didn't expect that this He Zhu and Yuan Ruihe would act as brokers, walking the news for Dugu Mo, attracting so many people to come and send them to death, the purpose is to dissolve the Ten Thousand Tribulation Divine Thunder!" Zheng Qian said secretly in his heart.

The big black dog seemed to know what Zheng Qian was thinking, smiled disdainfully, and said coldly: "The dog is not for himself, and the heavens and the earth will be destroyed, not to mention you people?"

As he spoke, the big black dog narrowed his eyes, stared at the constantly melting Tribulation Heavenly Thunder, smacked his lips, and said: "Hey, it's really a tyrannical thing, directly use the life essence blood to melt the Ten Thousand Tribulation Heavenly Thunder, if it were me, I would be able to collect all these Ten Thousand Tribulation Heavenly Thunder, and it would be able to be of great use when the time comes!"

Just as they were muttering, the Ten Thousand Tribulation Divine Thunder at the entrance of the valley in front of them had already melted into a hole, and Dugu Mo and them no longer hesitated, and quickly rushed inside, disappearing in the blink of an eye.

Zheng Qian also patted the big black dog, "Let's go, let's go and have a look!"
