After separating from Ye Fan, Zhou Tong quickly found a place where no one was, uncovered the deceptive array pattern on his body, and suddenly the fourth transformation of the dragon came to the heavenly tribulation.

The vast sea of thunder flooded the heavens and the earth in an instant, Zhou Tongpan sat in the void, ran the Thunder Emperor Method, and opened his mouth to completely swallow the heavy sea of thunder into his stomach and slowly refined.

His physical body, primordial spirit, and tyrant Zhong are all refining thunder together. Both the primordial gods and the physical body have gained a lot of benefits from the Thunder Sea, and they have already reached the realm of the fourth transformation of the dragon, and under the impetus of the Thunder Tribulation, they have taken a small step forward.

"Boom!"

In the end, the thunder tribulation of the fifth transformation of the dragon also descended.

The thunder tribulation is still helpless, and it has completely turned into Zhou Tong's nourishment, the law of the avenue in the thunder sea has turned into Zhou Tong's perception, and the essence of the thunder sea has turned into the nourishment that nourishes Zhou Tong's spirit and body, and the innate dao patterns in the thunder sea have been completely imprinted in the Ba Zhong, forming one innate god pattern after another.

This successive double tribulation lasted for half a day before finally dissipating.

After the Heavenly Tribulation, Zhou Tong had already advanced to the fifth transformation of the Dragon Transformation Secret Realm.

After advancing to the fifth transformation of the dragon, Zhou Tong spent a few days refining a Heavenly Dragon Origin again.

However, this time, it was not as intense as the first time, it was just a little bit of blood, which completely stabilized the cultivation of the fifth transformation of the dragon, and at the same time made the prototype of the true dragon god form in his wheel sea a little clearer.

After everything was ready, Zhou Tong rushed directly towards the Taichu Ancient Mine.

On the land of the Eastern Wilderness, there are a total of seven forbidden areas for life, and the most famous in the northern region is the Taichu Ancient Mine.

It was originally a source mine, but it became a Jedi. Moreover, with the name of "Taichu", it is meant that it existed before the opening of heaven and earth, and it is hard to imagine how old it is.

And a large area outside the Taichu Ancient Mine was almost entirely occupied by the major holy lands, because this was the most productive source mining area. In fact, about half of the sources of the major holy places come from here, and the sources produced by other places cannot be compared with here at all.

And outside the Taichu Ancient Mine, there is the only city standing - Source City!

However, Zhou Tong did not enter the Source City, he followed another road towards the Taichu Ancient Mine.

This road is also the path that Emperor Hengyu once walked.

When Emperor Hengyu went to the Taichu Ancient Mine to train his troops, he took this road. When Zhou Tong was watching the memories of the Immortal Phoenix Medicine in his previous life, he had seen Emperor Hengyu walk into here to refine his troops, so he knew very well how Emperor Hengyu went.

Emperor Hengyu entered all the way, so where he walked, all the weirdness and visions disappeared completely, even if someone rearranged it later, but it was not so strong.

The others didn't know what the forbidden areas or the creatures in the forbidden areas were, but Zhou Tong knew very well.

There are several kinds of creatures in the forbidden area, and the core of them is naturally the sleeping place of the Supreme; And next to this is the resting place of those supreme guardians or descendants; Then it's time to guard the Guardians, creatures that have been passed down from generation to generation.

Emperor Hengyu had killed a large number of these guardians and those creatures that had been passed down from generation to generation and guarded those guardians in the Taichu Ancient Mine.

It can be said that the places that Emperor Hengyu walked through at the beginning must have been swept away by him.

And after Emperor Hengyu, no emperor entered the Taichu Ancient Mine, so naturally no new guardian was born. Therefore, the road that Emperor Hengyu walked can be said to be the safest road, and everything weird and ominous is much weaker than other places.

The Taichu Ancient Mine was very large, and Zhou Tong walked for a whole day before approaching the center of the Ancient Mine.

Depression, fear, sorrow, mourning...... Fluctuating from the front, it was an emotion that got out of control.

Zhou Tong ran the martial arts heavenly eye and looked out, only to see the end of the distant earth, endless starlight sprinkled, like a stream of water, falling to the ground. The starlight in the sky converged into a river, white and boundless, flowing into the end of the heaven and earth, and it was from there that inexplicable fluctuations came.

"It's finally time to get to the most dangerous place, if not...... I don't want to come! There was a nine-colored halo shining in the center of Zhou Tong's eyebrows.

He used the previous word secret to resist the summoning power of the primordial ancient mine with all his might.

At the same time, he was constantly calculating in his mind that this area was already in a state of distortion of time and space. Emperor Hengyu walked in casually back then, but he couldn't walk in like this, he had to use the truth in the "Book of Yuantian" to calculate.

It has been several years since Zhou Tong got the "Book of Yuantian", and now he is not in the state of gambling in the Holy City, he has already studied the "Book of Yuantian"; At least dozens of times stronger than the original Ye Fan when he just got the "Book of Yuantian" and came here.

What followed was a tortuous journey, not to mention three steps forward and two steps back, Zhou Tong followed his understanding of the "Book of Yuantian", flickering left and right, moving forward very erratically.

Along the way, he also saw many strange creatures in the ancient mines of the primordial period, some of the weak ones were destroyed without saying a word, and some of the powerful ones were directly bypassed.

And there were several times in the middle, and the former word secretary kept warnings, and with such prompts, Zhou Tong passed all the crises of the Taichu Ancient Mine safely.

In the end, Zhou Tong came to his destination - Fallen Sun Ridge.

Wuri sinks, falls under the ridge, called the Fallen Sun Ridge, is the most rigid and sunny demon land, burns everything in the world, is one of the few fierce places in the world.

"Finally arrived at the destination, with the route that Emperor Hengyu walked back then, and it took so much effort!" Zhou Tong breathed a sigh of relief, and finally felt a little safer when he arrived here, "Get that piece of phoenix blood red gold, and leave here immediately!" ”

Entering the Fallen Sun Ridge, Zhou Tong soon saw a ruin.

It was an old building, not collapsed, and it had a plaque engraved with the word "Hengyu".

And on the back of this building, there are corpses all over the ground, all of which are the remains of those ancient creatures that disturbed Emperor Hengyu's military training in the first place.

"This is it, found it!" Zhou Tong's Martial Dao Heavenly Eye saw a piece of Phoenix Blood Red Gold in this ruin almost instantly, and he quickly pocketed this piece of Phoenix Blood Red Gold.

"It's time to leave, this place is too ominous, don't come again until I become a hegemon!" Zhou Tong left quickly, he didn't even dare to open the stone skin that sealed the phoenix blood red gold in the Taichu Ancient Mine, for fear that the light of the Phoenix Blood Red Gold would attract those creatures in the Taichu Ancient Mine.

The way out is much simpler, just follow the same path back as you came.

It took a day, and Zhou Tong quickly left the scope of the Taichu Ancient Mine and returned to the vast land of the Northern Regions.

"Finally left the Primal Ancient Mine!" After completely staying away from the Taichu Ancient Mine, Zhou Tong came out with a sigh of relief.

In the past few days in the Taichu Ancient Mine, he was so tired that he didn't dare to relax at all, the former word secretary was almost running at the highest speed throughout the whole process, and he was constantly using the "Book of Origin Heaven" to calculate the terrain in his heart.

"The next thing is the most important thing, I hope I guessed correctly!" Zhou Tong took out the phoenix blood red gold, a little apprehensive.
