On this day, in the main hall of Tianjiya, where Yang Yitian and everyone from Tianjiya were concentrated, it was obvious that something was being discussed, Yang Yitian explained something to everyone while speaking, and as soon as he finished speaking, he only heard Elder Qianda say loudly: "What? Master, you want to go alone to find the nine great spiritual veins?"

"Yes, I've been thinking about this for a long time, the key to the demon's current life is the leakage of the aura used to seal the nine spiritual veins of the Three Realms, and now the human race cultivation immortal realm is still a plate of scattered sand, it is difficult to resist the re-invasion of various races, I can only find a way to delay the speed of the leakage of the spiritual energy of the nine spiritual veins, so as to buy enough time for the human race to increase the chances of victory; Yang Yitian explained.

"Even so, you don't have to go alone! Now the situation is complicated, how dangerous it is for you to go out alone, the first time you went out, you were besieged by the three factions of the Demon Refining Sect last time, this time there will definitely be a greater danger, if you must go, you can bring more people to guard, in case of danger, you can also have a helper." Elder Qianda persuaded worriedly.

Others also persuaded him.

"I know everyone's kindness, but now I don't know when the seal will be completely broken, when the demons will appear, Tianjiya still needs the protection of the eight elders, and Fengye They also have to organize people from other sects to defend the surrounding towns, so as not to be attacked by demons, only I am more leisurely, so I can only go by myself, and I don't know the specific location of the nine spiritual veins, this time I just went out to try my luck, and it was useless if there were too many people. As for my safety, you can rest assured, it's a big deal that I can't run away, and if I want to leave, there won't be too many people who can forcibly leave me, right?" Yang Yitian insisted.

"Master, I think it's safest for you to sit in the Tianji Career at this time, you go out at this time, if something happens, how do you tell us to deal with ourselves?" Elder Qianda and the others continued to persuade.

"Don't worry, it's going to be fine, it's all decided, whether you agree or not, I'm going to go, let everyone come today just to tell you." Yang Yitian knew that everyone would not agree, so he did not discuss it with everyone in advance, and at this time, in order to let them stop stopping it, he could only show the authority of the head of the house.

Knowing that Yang Yitian had made up his mind, everyone didn't say anything anymore, only hoping that Yang Yitian would be able to return safely this time.

In fact, the reason why Yang Yitian wanted to go out alone was because it was inconvenient to take people to the place he was going to this time, and he went alone this time just to confirm a guess in his heart.

After leaving Tianjiya, Yang Yitian traveled with a sword, until a few years ago on Deling Island, where he fought for the first time, seeing everything on the island as before, Yang Yitian couldn't help but think of the situation when he and Bing Ruxue fought Heijiao here, when he had just come down the mountain, it was the first real battle, and he made himself grow a lot after that war, and he knew Bing Ruxue because of this.

Yang Yitian walked to the stone monument by the river, flew all the way, jumped towards the stone monument, and disappeared into the stone tablet like the first time, after entering the enchantment, Yang Yitian turned around, and came to the stone hall where he was almost trapped at the beginning, and felt that the aura in the stone was even richer than back then, and said in his heart: "It seems that there is nothing wrong this time." Looking at the familiar scene, he was a little emotional, but at this time, it was not the time to be nostalgic, Yang Yitian looked up at the starry sky pattern above the main hall, when he saw the pattern of the nine-star alignment on the Tianji Ya, Yang Yitian vaguely remembered the starry sky pattern he saw in this secret realm on Deling Island. This pattern is very similar to the mural pattern on Tianjiya.

Seeing this, Yang Yitian finally confirmed his previous guess, this place is the same as Tianjiya, it is also a spiritual vein, and the first spiritual vein of Tianjiya is the same, it is sealed by the formation, but the sealing techniques are different, the seal on Tianjiya is the power of the formation of the nine sword peaks, and the Yang Yitian used here Judging from the previous setting in the stone hall, he guessed that it should be the power of yin and yang.

Last time, because he was almost trapped here, he left in a hurry, so he didn't conduct a careful exploration of this place, this time, Yang Yitian came deliberately, of course, he wouldn't miss it, touched the ground with one hand, and sent out a spiritual power in his palm, centered on himself, spreading around, closing his eyes tightly, perceiving the surrounding movements from time to time, a quarter of an hour later, after some careful exploration, Yang Yitian finally found a clue, and said to himself: " The enchantment here is the same as the enchantment on the stone tablet outside, it is the master's unique enchantment, has the master ever been here? The enchantment here was laid by the master? And look at the traces here, there is a layer of enchantment that has been damaged under the master's enchantment, and the master should want to repair the damaged enchantment here. ”

If the last time he came, Yang Yitian only suspected that the enchantment here was related to his master, then this time he was already able to confirm that this was indeed the enchantment laid by his master, but what Yang Yitian didn't understand was why his master laid so many enchantments here, and they were all very powerful, if he wasn't familiar with it, even if others came here, they wouldn't be able to get in.

"What kind of secret is hidden here, so that the master does not hesitate to spend so much energy to prevent outsiders from entering here?" After it must have been done by his own master, Yang Yitian became even more curious about this place.

I saw Yang Yitian's hands sealed, and made a few complex gestures, the movements were even faster so that it was difficult to see clearly, and then said to the yin and yang fish pattern in the middle: "Heaven and earth are yellow, the earth is divided into yin and yang, open the formation!"

I saw that Yang Yitian's hands were in the air as if he was forcefully separating something, and even his face was swollen red, and it didn't take long for the main hall to hear a slow sound of vibration, and then, the yin and yang fish pattern that was originally tightly combined in the center of the hall was actually separated, revealing a gap, and the gap was slowly widening, but from under this gap there was a rich and abnormal aura, and when the yin and yang fish were completely opened, revealing a large circular hole, the hole was covered by a transparent enchantment.

Yang Yitian jumped into the big circular hole and suddenly disappeared into the hole.

The next moment, Yang Yitian appeared in an underground world, only to see that it was extremely empty, but the aura in the air was unusually rich, that is, Yang Yitian had not felt such a rich aura on the Ninth Sword Peak of Tianjiya. If the aura here made Yang Yitian feel a little puzzled, then the scene he saw in front of him made him suspect that he was dreaming.

I saw that in the empty underground world, a giant tripod was suspended and stood in the sky, and directly below the tripod, a unicorn beast mixed with a transparent and soft body like water was lying on the ground, it seemed to be asleep, and the breath breathed out by this unicorn in the sleep was pure and primitive aura; 。

"Could it be that this is the legendary Jiuding used by Xia Yu's predecessors to seal the Three Realms? So this water unicorn beast under the ding is the legendary spiritual vein?" Yang Yitian calmed his restless mood and muttered to himself.

Yang Yitian once saw in the "Three Realms Secret Collection", the legend is that there are nine spiritual veins in the world, born with the luck of heaven and earth, each with a special shape, sucking wind and drinking dew, and breathing into the spirit, which is the foundation of the operation of heaven and earth, but the alien shape transformed by these nine spiritual veins is lazy by nature, and spends most of his life in sleep, rarely moving places, and often sleeps for thousands or even tens of thousands of years in each place.

Looking at this scene in front of him, Yang Yitian finally knew why his master had laid down such a heavy enchantment and forbidden formation outside, such a place was a treasure land that was rare in 10,000 years for any person or sect, but if this treasure land was damaged, the seal would definitely be affected, and the consequences would definitely be the destruction of all living beings in the world.

"Since the master has been here before, and he has also laid an enchantment to prevent outsiders from entering, does the master also know about the Three Realms Seal and the Nine Great Spirit Veins?" Yang Yitian couldn't help but wonder in a low voice when he saw this, and then contacted what his master had done.

At this time, Yang Yitian didn't dare to make a sound to disturb again, for fear of waking up the sleeping beast, and then look at the ground where the beast was located, there was a nine-dot around the beast, just surrounded by the beast in the middle, Yang Yitian looked at the magic circle pattern on the ground, and said in his heart: "I'm afraid this is the nine-star anti-heaven array that Xia Yu's predecessors said, but this is only one of the nine arrays."

Looking at the trace of aura escaping from the giant tripod, Yang Yitian said: "This is the part of the aura that escaped after the seal was loosened, which led to the leakage of the great array of spiritual power, and the speed of this escape has shown signs of accelerating, in just a few months, it has changed the intensity of the aura in the outside world, causing everyone's cultivation to rise overnight, I am afraid that this is also the case in several other seals, when all the aura in the nine tripods escapes, it is when the nine-star anti-heaven great array collapses and the seal of the Three Realms dissipates." ”

Faced with the predicament in front of him, Yang Yitian was also helpless, there was no better way to prevent the escape of the aura, and he did not dare to act indiscriminately, for fear that if he was not careful, not only would he not delay the speed of the aura's escape, but also let the power of the seal disappear in advance, and he would become a sinner of the human race.

"Well, you don't have to rush some things, you have to think of a foolproof plan. After Yang Yitian made up his mind, he returned to the stone hall according to the original way, restored the entrance of the stone hall as it was, and got up to leave.
