After being separated from Ye Fan, Zhou Tong quickly found a place where no one was, uncovered the pattern of the deception formation on his body, and immediately turned into a dragon and the fourth transformation of the heavenly tribulation came.

The vast sea of ​​thunder drowned the world in an instant. Zhou Tong sat cross-legged in the void, operatively wielded the Thunder Emperor's Technique, opened his mouth and swallowed the sea of ​​thunder after layer and slowly refined it.

His body, soul, and the Ba Zhong were all refining thunder together. The soul and body both gained a lot of benefits from the sea of ​​thunder. They had already reached the fourth transformation of the dragon, and under the driving force of the thunder tribulation, they took a small step forward.

"Boom!"

Finally, the fifth transformation of the dragon also came down.

The thunder tribulation still couldn't do anything to Zhou Tong, and it completely turned into Zhou Tong's nutrients. The great laws of the Dao in the sea of ​​thunder turned into Zhou Tong's perception. The essence of the sea of ​​thunder turned into the nutrients to nourish Zhou Tong's soul and body. The innate Tao patterns in the sea of ​​thunder were completely imprinted in the Ba Zhong, forming one innate god patterns after another.

This two-level heavenly tribulation lasted for half a day before finally dissipating.

After the heavenly tribulation, Zhou Tong has 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 to refine the origin of the dragon again.

However, this time, it was not as intense as the first time. I just changed some blood and completely stabilized the cultivation level of the fifth transformation of the dragon, and at the same time made the prototype of the real dragon in the sea of ​​wheels a little clearer.

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

There are seven forbidden zones for life on the land of the Eastern Wilderness, and the most famous one in the northern region is the Taichu Ancient Mine.

This place was originally a source mine, but it became a Jedi. It was named "Taichu" and intended to exist before the world opened. It is hard to imagine how long it was.

The large areas outside the Taichu Ancient Mine are almost all occupied by major holy places because this is the most abundant source mining area. In fact, about half of the sources of major holy places come from here, and the sources produced in other places cannot be compared with here.

And outside the Taichu ancient mine, the only city stands - Yuancheng!

However, Zhou Tong did not enter Yuancheng. He followed another road towards the Taichu Ancient Mine.

This path was also the path that Emperor Hengyu once walked.

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

Emperor Hengyu rushed in all the way, so all the strangeness and visions he walked through disappeared completely. Even if someone redesigned it later, it was not that strong.

Others don’t know what the creatures in the restricted areas or the restricted areas are, but Zhou Tong is very clear.

There are several creatures in the forbidden area, and the most core of them is naturally the supreme sleeping places; and the second only to this are the supreme guardians or the sleeping places of later generations; the next thing is to protect those guardians, creatures passed down from generation to generation.

Emperor Hengyu killed a large number of such guardians and creatures that passed down from generation to generation in the Taichu ancient mine.

It can be said that the places that Emperor Hengyu had walked through must have been cleaned up by him.

After Emperor Hengyu, no emperor took over the Taichu Ancient Mine, so naturally no new guardian was born. Therefore, the path that Emperor Hengyu took can be said to be the safest road, and all the weirdness and unknown things are much weaker than other places.

The ancient ore of Taichu was very large. Zhou Tong walked all day before he approached the center of the ancient ore.

Depression, fear, sorrow, grief... from the fluctuations ahead, it is an out of control emotion.

Zhou Tong turned his martial arts eyes and looked at the end of the distant earth, endless starlight scattered, like a stream of water, hanging towards the ground. The starlight in the sky gathered into a river, and the vast white area flowed into the end of the world. The inexplicable fluctuations came from there.

"I'm finally coming to the most dangerous place. If it weren't... I really didn't want to come!" There was a nine-color halo in Zhou Tong's eyebrows.

He used the secret of the previous word to do his best to resist the summoning power in the ancient Taichu mine.

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 could not walk in like this. He had to use the principles in the Book of Origin to calculate.

Zhou Tong has been given the "Source Book of Origin". Now he is not the same as when he was gambled in the Holy City. He has already made some research on the "Source Book of Origin"; at least it is dozens of times better than when Ye Fan came here as soon as he got the "Source Book of Origin".

The next step was a tortuous journey. Not to mention three steps and two steps, Zhou Tong moved forward very erraticly according to his understanding of the Book of Source Heaven.

Along the way, he also saw many strange creatures in the ancient Taichu mine. Some of the weak ones were destroyed without saying a word. Some powerful ones were directly avoided.

Moreover, there were several times in the middle, and the secret of the previous letter kept warning. With such a prompt, Zhou Tong safely passed all the crises of the Taichu Ancient Mine.

Finally, Zhou Tong came to his destination - Soriling.

The dark sun falls and falls below the ridge, which is called the ridge of the sun. It is the most powerful and yang demonic land. It burns everything in the world and is one of the most miserable places in the world.

"I finally arrived at the destination. I had so much effort with the route that Emperor Hengyu took back then!" Zhou Tong suddenly breathed a sigh of relief. He finally became a little safer when he arrived here. "If you get that piece of Phoenix Blood Red Gold, leave here immediately!"

Entering the Soaring Ridge, Zhou Tong soon saw a ruin.

It was an ancient building that had not collapsed. It had a plaque engraved with the word "Hengyu".

On the back of this building are corpses all over the ground, all of which are the remains of the ancient creatures that disturbed Emperor Hengyu's training.

"It's here, I found it!" Zhou Tong's martial arts sky eye saw a piece of phoenix blood red gold in the ruins almost instantly, and he quickly put the phoenix blood red gold into his bag.

"It's time to leave. This place is too unknown. Don't come again before I become a powerful body!" 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 Phoenix Blood Red Gold's light attracted the creatures from the Taichu Ancient Mine.

The road to get out is much simpler, just go back directly along the original path.

After spending a day, Zhou Tong quickly left the scope of the Taichu Ancient Mine and returned to the vast land of the Northern Region.

"I finally left the Taichu Ancient Mine!" After completely staying away from the Taichu Ancient Mine, Zhou Tong breathed a sigh of relief.

During those days in the Taichu Ancient Mine, he was so tired that he didn't dare to relax at all. The secret of Qianzi was running at the highest speed almost throughout the journey, and he was constantly using the "Sutra of the Origin" to calculate the terrain in his heart.
