The underground passage was dark and chaotic, apparently suffering varying degrees of damage.

After walking for about an hour, the passage was completely cleared and they came to the rumored underground cage, and everyone was stunned by the scene in front of them.

"How so?"

Tang Yin looked at the bubbling magma like a sea of fire, and was also shocked by the scene in front of him, and before entering this space, he didn't even feel the slightest heat.

"It's a large space closure array!" After observing the surroundings, Xuanyuan Nishang said, "Since the formation has been destroyed, its thermal insulation effect still exists!" ”

"Have you noticed that the magma here has a strong smell of sulfur, which means that the scorched earth outside should have something to do with it?" Tang Yin asked.

"However, there is no trace of lava leading to the outside world! It shouldn't have anything to do with this! Xuanyuan Yulong shook his head and denied Tang Yin's judgment.

Tang Yin smiled, did not refute, but raised his hand with a wave, and the strong wind in his palm erupted, and a tornado whirlwind suddenly rose in the magma pool!

"Tang Yin! What are you doing? ”

Everyone was shocked, and they urged Zhenyuan to open the posture and prepare for battle.

"It's okay, don't be nervous!" Tang Yin smiled apologetically and said, "I feel that there should be something under this magma, I'll just test it!" ”

As soon as Tang Yin's words fell, the bubbling magma really reacted, and a red afterimage rushed out from below. Everyone was already prepared, and barely let the afterimage come ashore, they bombarded it, and the carrion fell into the magma and disappeared in a blink of an eye.

But everyone's eyes were sharp, and they had already seen the appearance of that thing, and it turned out to be a third-level demon beast rock lizard.

The rock lizard is a monster beast that lives in magma, and its own level is not too high, but as long as it does not leave the magma, it has almost no natural enemies, so this thing generally breeds in a large area and lives in groups.

Tang Yin's heart moved, and he said, "Senior brothers and sisters, who is willing to go down to the magma with the junior brother to have a look?" ”

"What? Down to the bottom of the lava? ”

"Tang Yin, are you crazy?"

Everyone is a strong person beyond the realm of the Nine Tribulations, and the true yuan is not afraid of the high temperature of the magma for a short period of time after protecting the body, but there will still be danger after a long time, after all, the true yuan of the sword master is not endless, there are a large number of rock lizards living in the magma, and those guys are almost invincible in the magma!

Tang Yin's proposal is really crazy!

"Okay!" Tang Yin shook his head and said, "Since everyone is unwilling to go down with the little brother, then I'll go down and see for myself!" ”

After saying that, Tang Yin didn't wait for everyone to react, so he jumped and got into the magma.

"Senior Brother ......"

Xuanyuan Nishang couldn't dissuade her, and jumped down.

On the shore, everyone looked at Tang Yin and Xuanyuan Nishang who jumped into the magma pool one after another, and felt that these two people were really crazy.

"Senior Brother Long, what should we do?"

Xuanyuan Nishang was not there, and everyone had to shift their attention to Xuanyuan Yulong, who had the highest strength here.

"Wait and see!"

Xuanyuan Yulong looked at the bubbling magma, his eyes flickered, in fact, deep in his heart, he also wanted to jump down. But all the junior brothers and sisters behind him looked at him, and it was not good for him to drag everyone into the unknown abyss before the situation was clear.

Underneath the magma, a cloud of True Yuan Energy rose around Tang Yin and Xuanyuan Nishang's bodies, separating the bubbling magma. After descending ten meters, the two of them found that there was no magma below, but a mysterious space. A layer of magical energy shrouded the space, completely separating the magma.

Tang Yin and the others easily passed through the mysterious energy shield and entered the interior of the space, and found that this was the legendary underground cage.

Legend has it that the predecessor who had transcended the realm of the Holy Dao had imprisoned himself here for thousands of years.

But at this moment, Tang Yin saw the severed cold iron chains, a few pools of coagulated blood, and the senior was no longer there.

"Senior sister, this is where your ancestor is imprisoned, can you see something?" Tang Yin asked.

Xuanyuan Nishang did not respond to Tang Yin, but made several handprints in his hand one after another, and the golden light suddenly appeared and floated, and the situation of the day was reproduced.

Tang Yin secretly praised, worthy of being from an ancient clan, with countless magic weapons on his body, he was able to recreate the past time according to the breath left here.

In the shadow, a thin old man was imprisoned by dozens of cold iron chains, he was sometimes crazy and sometimes sober, constantly cultivating when he was awake, and constantly pulling the cold iron chains when he was crazy.

Xuanyuan Nishang watched the scene reappear in the virtual shadow, and couldn't help but burst into tears. That old man was Xuanyuan Tai'a, the founding emperor of the Dragon Bird Empire, and the third dean of the Tibetan Sword Academy and the first dean of the Inner Court.

It is really the saddest thing in life for a supreme who escaped from the Nine Heavens Divine Domain to be seriously injured and devoured by divine powers, and he was unable to dominate his body.

Xuanyuan Tai'a left a great name back then, but he didn't expect that his life in his later years would be like this for thousands of years.

But whether he is sober or insane, his supernatural realm is constantly improving. Tang Yin speculated that if there was no accident, he would definitely have surpassed the Spirit Sword Continent's cognition of the Nine Star Sacred Dao and entered a higher realm level.

And at this moment, there were suddenly more than a dozen figures in the phantom, looking at their clothes, Tang Yin was very familiar with it, it was the law enforcement messenger of the Soul Palace. The three gold-robed envoys and the ten silver-robed envoys, other than that, the leader turned out to be only a young man in his twenties.

I saw that the man, dressed in white, shook a gold-painted folding fan in his hand, and was holding a personable human immortal, who was the figure of the nine immortals known as the Nine Princes.

"Sure enough, it has something to do with the Soul Palace!" Tang Yin and Xuanyuan Nishang glanced at each other, and the two of them were really familiar with the dress of the people in the Soul Palace.

Although Xuanyuan Tai'a had the strength to surpass the Nine Star Saint Dao, dozens of cold iron chains that penetrated into the vital points of his body had already locked him firmly, and he couldn't use a single point of strength.

Soon, Xuanyuan Tai'a was captured, and the people of the Soul Hall cut off the cold iron chains with super weapons, taking the person away, and the phantom imaging ended here.

"Soul Palace! It's the Soul Hall again! Xuanyuan Nishang clenched his fists, his fingertips piercing the flesh of his palm, still unaware.

Tang Yin said with concern: "Senior sister, your hand is ......."

"It's okay, now that the clues have been found, we must go to the Soul Hall headquarters as soon as possible to rescue the ancestor, otherwise it will be really troublesome to be taken away by those people in the Nine Heavens God Domain!" Xuanyuan said.

"That's true, a Saint Dao level sword spirit is enough to refine a divine sword." Tang Yin said solemnly,

Since the conspiracy of the Starry Sky Trial was exposed by Tang Yin and the others, everyone in the Sword Master cultivators was in danger, especially those who had cultivated to a high level, lest they become the prey of those people in the Nine Heavens Divine Domain.
