After making preparations, Zhou Tong quickly walked towards a dragon vein due east.

The dragon vein he chose happened to be the one due east, and it was also the road that Ye Fan said he had walked in the original book.

With the guidance of the original book, he is most familiar with this road, and the other eight roads know what demons and monsters will be encountered. To be on the safe side, let's take this most familiar path.

The tall stone ridge was bare, reddish-brown, with no vegetation and a touch of purple, similar to the purple mountain.

Zhou Tong did not directly do it, penetrating the earth and going deeper, but patiently searched, and finally found an ancient mine, and he quickly followed this mining area into the depths of the dragon vein.

The mine was so deep that he descended three thousand meters before finally reaching the surface.

This dark ancient mine was excavated more than 100,000 years ago, and it is full of the breath of time, and at the same time, it is extremely quiet.

"Purple sunlight!"

Zhou Tong read softly, and suddenly a purple light floated out of Zhou Tong's body. Zhou Tong poured wisps of divine power into this Great Sage Secret Treasure, and suddenly a faint purple light illuminated the way forward.

The lights weren't very bright, because Zhou Tong didn't expend much power.

Of course, with Zhou Tong's current strength, he can't urge such a great sage secret treasure.

However, this Great Sage Secret Treasure has absorbed the essence of Kunlun on the Dragon Mountain for I don't know how many years, and it itself contains enough power to be able to hit the three strikes of the Great Sage!

Although there are only three blows, this is where Zhou Tong's greatest confidence lies now.

Holy soldiers, imperial soldiers and the like, why there is a process of "resurrection", in fact, is that the power left inside these weapons is not enough, after all, it is a weapon and not a person, and it will not spit it out on its own.

And Zhou Tong's purple sun lantern has been passively nourished by the essence of Longshan for I don't know how many years on Longshan, and it has stored enough power in itself.

Zhou Tong took the violet lantern and continued to advance along the dark mine road.

"Brush!"

Not long after walking, suddenly, a humanoid creature fluttered its wings and rushed towards it. This is an ancient creature, and the weakest of those ancient creatures.

Zhou Tong pointed out directly, and a sword light slashed this ancient creature.

It is a creature that looks very much like a humanoid bat.

This is a species that lives underground, called the magic bat, and is extremely rare. But the place where this creature lives, without exception, is definitely a place of great evil.

Zhou Tong continued to move forward, and along the way he encountered hundreds of demon bats, and he was unrelenting, and those who dared to rush up were killed. It wasn't until the last huge demon bat, which was five meters high, was slashed by Zhou Tong with a sword, that this ancient mine quieted down.

After moving forward for dozens of miles, he saw the paintings on the walls of the mine through the faint light of the violet lantern.

These paintings are all about mining in those days, and at first they were unremarkable and trivial, but as they went deeper, some strange things appeared.

Ancient creatures were dug up, causing a monstrous catastrophe and rivers of blood flowed from the earth. The last Emperor came here and suppressed all the creatures that were in trouble.

"This is the power of the Emperor of the Beginningless Emperor when he came to dominate here!" Zhou Tong said in his heart.

However, the mural was quickly broken, and Zhou Tong did not see the final result.

Zhou Tong continued to walk forward, and soon walked out for more than thirty miles, and at this time, the ground had become gray-white, which was the color of ashes; At the same time, the yin qi here is getting heavier and heavier, and it is becoming more and more cold and biting.

Moving on, the ancient mine was already like an ice cellar, and the cold air was scraping on people's skin like knives.

"Woo ......"

The yin wind was howling, the shadows were sufficient, and among the piles of dry bones, hazy ghost shadows appeared, very faint.

Zhou Tong glanced at these ghosts, and instilled a divine power into the purple sun lamp, and suddenly the light shone brightly, wisps of holy power appeared, those ghosts suddenly dissipated, and at the same time, the whistling sounds here gradually stopped and became much quieter.

"A group of cowards who bully the soft and are afraid of the hard!" Zhou Tong was disdainful.

When you notice someone coming in, you are ready to move; Sensing the slightest wisp of holy power, he quickly quieted down.

Such a "ghost", such a human "ghost", there is nothing to be afraid of.

But when Zhou Tong had advanced for a total of about forty miles, the eerie atmosphere here was reversed, and a peaceful and rich aura began to emerge gradually.

At the same time, a bright world emerges in front of us, with a soft brilliance flowing, a piece of peace and holiness.

After continuing to walk forward for a mile or so, Zhou Tong came to the place where the aura was the strongest; And in parallel with the aura, there is also an amazing killing machine.

"Yin and Yang Eyes!" Zhou Tong said silently in his heart.

Just ahead, there are two large holes, one with a spiritual aura soaring to the sky, and constantly having active qi rolling up; The other was furious, as if countless swords were flickering.

Moreover, the mouth of the cave where the source gas was spewed was surrounded by a pile of fossilized bones; And the entrance of the cave where the evil qi was spewed was surrounded by peace, and the source stones were everywhere.

These two holes, negative yin and embrace yang, negative yang and hold yin, this is completely a natural Taiji diagram.

"You have to show a trace of holy power to get in!" Zhou Tong looked at the purple sun lamp beside him, and a divine thought was suddenly poured into it.

"Buzz!!"

In an instant, the power stored in the purple yang lamp surged, and a brilliant purple light instantly rushed out from the lamp, directly penetrating into the Taiji diagram.

The purple sun lantern is worthy of being the treasure of the Great Sage, and the power it generates is extremely terrifying.

This purple light looked unremarkable, but it directly turned into a brilliant purple avenue, and any source qi and murderous qi were completely isolated. This murderous endless yin and yang eye was broken open in an instant.

Zhou Tong's figure flashed, and he had already rushed into the Taiji diagram with the purple yang lamp in an instant, and then the purple light dissipated, and the yin and yang eyes returned to their original state.

"The saint-level blow has been used...... But fortunately, it is only a saint-level blow, and for the purple sun lamp, the consumption is not large. Zhou Tong carefully inspected the violet lantern, and roughly calculated in his heart that this blow would probably consume one thousandth of the stored power in the violet lantern.

"If it's just to show the power of the saint level, this purple sun lantern may be able to crown the Beidou! After all, the other heirloom saints didn't have the kind of environment of the violet lantern. Zhou Tong couldn't help but have a smile on his face, worthy of the peerless treasure that he brought out from Kunlun Dragon Mountain regardless of the danger.

After checking the purple sun lantern, Zhou Tong saw that the mine road had come to an end, and there was Purple Mountain in front of him. Because the purple wall in front of it is the unique color of the rocks on the purple mountain.

"Purple Mountain! Finally in! ”

Zhou Tong pointed like a sword, directly split the rock in front of him, and walked inside.

And just after Zhou Tong entered, the rocks behind him also closed down, and this purple mountain seemed to have life.

Seeing this, Zhou Tong accelerated the speed of splitting the mountain.

"Boom!"

But with the last loud bang, as Zhou Tong split the last rock, his eyes were hazy, and the green jade in front of him was a staircase, and the white jade was a portal, and a magnificent building appeared.

He finally came to his destination and entered the interior of the Purple Mountain.
