Su Rui was holding the Sword of Killing Immortals in his right hand, and he was holding a purple crystal card in the other hand, and he could see that there was a bright point of light flashing on the purple crystal card, and the purple crystal card was guiding a certain direction.

"The people of the Purple Crowned Heavenly Snake Clan are listening, now I don't have time to deal with you, but today you have all remembered it for me, one day I will uproot the entire Purple Crowned Heavenly Snake Clan, and let you filthy reptiles disappear completely!"

After saying that, Su Rui slashed out with a sword, and the sword light of the Immortal Killing Sword burst out, forcibly cutting out a gap in the divine domain of the Purple Crowned Snake God, and the Immortal Array disappeared with Su Rui in a flash.

"Father, he ......" The young ancestor's face changed slightly.

The purple-crowned snake god said with a gloomy gaze: "Is it because this god has been sleeping for too long, or is it that people in this era are so arrogant that they dare to say such things in front of this god!"

"Father, I can't let him go, or it will be a woe to me. Young Ancestor said nervously.

"Do you still have to say that?"

A cruel smile appeared on the face of the purple-crowned snake god and said, "Very interesting little guy, it seems that there are a lot of secrets on him, I hope I don't disappoint him!"

After speaking, the body flickered, and the purple-crowned snake god had disappeared, and with it, there was also a spread out divine domain.

After the Purple Crowned Snake God disappeared, the Young Ancestor breathed a sigh of relief and stood up from the cold altar. The other Purple Crowned Heavenly Snake Clan powerhouses also slowly got up, although the Purple Crowned Snake God was their Emperor God Ancient Ancestor, they were all seeing it with their own eyes.

"Great Ancestor, Ancient Ancestor...... Can Gu Zu catch that person?" a Saint Realm powerhouse hesitated.

The Young Ancestor was silent, if it was before, he naturally wouldn't have any doubts. The power of the divine throne is unimaginable under the divine position, and the only one in the divine realm can make the existence under the divine throne have no power to resist.

But that person relied on a strange formation diagram and a terrifying killing sword to block the power of the Divine Domain, and even broke through the Divine Domain and escaped, which was simply incredible.

After Su Rui broke through the Purple Crowned Snake God's divine domain, he immediately cut through the independent space formed by the altar, and stepped on the Immortal Formation Diagram and instantly submerged into the underground fire veins.

At the moment when he submerged into the underground fire vein, the terrifying high temperature came to his face, this was only the surface of the underground fire vein, and the deeper he went into the underground fire vein, the more terrifying the temperature became.

The terrible heat is nothing, and the real horror in the underground fire veins is fire smoke, fire poison, earth fire, and all kinds of unknown and inexplicable existences.

With the Zhu Immortal Array and the Immortal Sword to protect him, Su Rui was eager to save his father, and in an instant, he went deep into the underground fire veins three thousand zhang deep. It's a black and red hue, like a legendary lava hell, with billowing black smoke and fierce fire poison filling the surroundings.

At this depth, even the Lingtai Realm is simply impossible to withstand, just the fire smoke and fire poison are enough to easily kill the great cultivators of the Lingtai Realm, and only the powerhouses of the Divine Fetus Realm can barely reach here.

It stands to reason that with Su Zhenyuan's cultivation in the Lingtai Realm, even this depth cannot be reached at all, but the purple crystal plate in Su Rui's hand shows that Su Zhenyuan is still in a deeper place with underground fire veins.

Su Rui knew that his father had an adventure when he was young, and he had entered the Emperor God Cave Mansion and obtained the inheritance relics left by the Emperor God in ancient times, so it was not necessarily impossible to reach the deeper underground fire veins.

Stepping on the Immortal Formation Diagram, Su Rui searched deeper into the underground fire veins, and as he continued to go deeper into the depths of the underground fire veins, the black and red around him gradually dyed a touch of purple, which looked extremely strange and terrifying.

Where the underground fire veins are five thousand zhang deep, the high temperature here is already enough to melt the ordinary Heavenly Rank Desolate Weapon, even the Divine Fetus Realm can't survive here, this is already a forbidden place under the Holy Realm.

Although this place is extremely terrifying and no one has set foot in it for a long time, it has also given birth to many rare natural treasures in the outside world.

The most of them is Chiyang Stone, the dense Chiyang Stone is exposed, emitting a red light in the underground fire vein, from the lower grade Chiyang Stone, the middle grade Chiyang Stone, the upper grade Chiyang Stone to the best Chiyang Stone.

Not to mention the red sun stones hidden in the depths, there are more than 10,000 red sun stones exposed to the outside alone, and if all of them are mined, the value is incalculable.

However, Su Rui didn't have the time to pay attention to any red sun stone at all, even in the face of the extremely precious, extremely rare in the outside world, the best red sun stone was indifferent.

At this time, Su Rui relied on the flesh of the Su Realm and the power of the Jade Brake Niangniang, even if the body of the Su Realm was transformed by the World Tree, the power of carrying the Jade Brake Niangniang was also damaging this body at all times.

For the Chiyang Stone to stay for a moment, the more serious the physical damage suffered by the Good Corpse Su Realm, it is not worth it at all.

"Lord, the little serpent followed. The voice of the empty tooth sounded in Su Rui's consciousness.

Su Rui immediately shared the vision of the empty teeth, and a snaking purple light in the field of vision followed closely behind him, not far or close. Although Su Rui used the power of the Jade Brake Niangniang, all his mind was looking for his father Su Zhenyuan, and if it weren't for the empty tooth reminder, he wouldn't have known that the Purple Crowned Snake God was following behind him.

"Now is not the time to deal with him, it is important to find his father!"

Su Rui ignored the Purple Crowned Snake God who was following closely behind, but let Empty Tooth keep an eye on him all the time, and all his thoughts were on finding his father Su Zhenyuan.

After going deep into the underground fire vein, the purple crystal card in his hand suddenly exploded, and a purple light shot out from the exploded crystal card.

Su Rui followed the purple light, and soon came to a mysterious and unknown place in the underground fire vein, and before he got close to that mysterious and unknown place, an indescribable sense of crisis had already come to his face.

It was a lake with a radius of 3,000 feet, but there was no water in the lake, but something as thick as melted golden juice.

In the middle of the lake there is a small island about 500 zhang in radius, and there is a strange wild plant growing everywhere on the whole island, the wild plant of different heights is silver and white, curved like a long snake, and the surface is covered with silver-white scales.

The closer you get to the strange plants in the middle of the island, the more vigorous they become, and some of them also bloom with silvery white flowers that spray light and rain, and a few strange plants bear silvery white glowing fruits.

Thousands of strange desolate plants seem to have built a nest, and in the center of the nest lies an egg about ten feet high and wrapped in platinum scales.

"Father!"

Su Rui finally found his father Su Zhenyuan in a corner of the lake, Su Zhenyuan had a fist-sized stove suspended above his head, and the crimson light fell from the furnace as it slowly rotated, and a divine power that could not be triggered emanated from the stove.

Obviously, this furnace is a complete artifact, and Su Zhenyuan can urge the furnace, and it is the furnace that has sheltered him all the way here.

The furnace suspended above Su Zhenyuan's head slowly rotated, and the golden juice-like things in the lake continued to sink into the furnace, and the power emitted by the furnace was gradually increasing, and at the same time, Su Zhenyuan's cultivation seemed to be constantly improving.
