The person who searched for Lu Dongtian's father and drew a map was also a woman among the thirteen, dressed in men's clothes, with her hair coiled up, wearing a hat, and with clear eyebrows, as if she knew a scholar.

This woman's name is Hao Xin, her strength is not high, she only has the Heaven Breaking Double Realm, and her combat power is not Lu Dongtian's opponent, if she didn't have the ability to search for people, she wouldn't be standing here.

"Senior Sister Hao Xin, you can tell you about the terrain here." Lu Dongtian said directly.

Hao Xin nodded, did not show dissatisfaction, stretched out his finger, pointed there and said: "This place is called the Blood Jade Great Plains, and the underground demons are hiding under the plain. Blood jade is abundant there, which is suitable for underground demons to collect essence blood, and there may be a large number of underground demons. ”

Speaking of this, Hao Xin paused, glanced at Lu Dongtian, and then looked at everyone. It means that there are a large number of underground demons there, and there are only fifteen of us, so we are afraid that there will be no return.

The rest of the people also looked at Lu Dongtian, although their realm was higher than Lu Dongtian, but their background was not as good, this time he was the initiator, so they naturally had to listen to his opinion.

In the face of the demons in the underground, they are not necessarily opponents alone, let alone group fights.

Lu Dongtian took out three talismans and said, "Don't worry, I have three talismans here, one Divine Escape Talisman, which can lead everyone to escape 10,000 miles together." Two unbreakable vajra talismans can withstand the attack of the earth-shattering triple powerhouse for three breaths. These three talismans were given to me by my master, so I believe you can rest assured. ”

When everyone saw the talisman in Lu Dongtian's hand, they felt the breath of the powerhouse of the Heaven-shattering Realm, and finally put their minds at ease.

Hao Xin continued: "Senior Brother Lu, the underground demon lair is complicated, and I can follow all the way with your father's breath, but your father seems to have been taken to the depths, and my strength cannot continue to follow, only to the second layer underground, and I don't know much about the road behind." ”

Lu Dongtian nodded and said, "Knowing the place is enough. This time, we went to the lair of the demons underground, just to save people, and as soon as we saved people, we immediately withdrew, without the slightest hesitation. Let's go, let's go now, Senior Sister Hao Xin, you lead the way. ”

Fifteen people took off into the air, flew out of the Hundred Xuandong Mansion, and flew towards the Blood Jade Great Plains.

After a day and a night of hurrying, everyone stopped, they flew with all their might, and finally came to the edge of the Blood Jade Great Plain, at this time they were exhausted and needed to recover their true yuan.

The Great Plains of Blood Jade, just when I came to the edge, I could smell a smell of blood, but the smell of blood was not disgusting, but with a hint of freshness.

The smell of blood here is emanating from the blood jade, it is all pure blood, there are no stains, so there is no smell.

Tan Yi looked at it from a distance, and the land of the Blood Jade Great Plains was slightly reddish, as if the land had once been stained with blood.

"Everyone rest in place for half an hour, recover the true yuan as soon as possible, my father has been taken away for a few days, and there is no time to delay!" Lu Dongtian sat down cross-legged, swallowed the next Replenishing Yuan Pill, and ran the exercises to absorb the immortal qi of this region.

Tan Yi saw Lu Dongtian taking the Replenishing Yuan Pill and was about to take out the pill to distribute to everyone, only to remember that he hadn't made an alchemy for a while, and the pills on his body were all spirit-level pills used during the martial arts period. Even if there is an elixir, it is also the Jingyuan Pill and the Zhuji Dan, which are useless for replenishing the True Yuan.

"When this matter is over, I have to refine a few furnaces of elixir." Tan Yi also sat down cross-legged, running exercises to absorb immortal qi and replenish true yuan.

The rest of the people also began to recover the true element, and the four powerhouses who broke the sky and the triple layer joined forces to set up a simple formation to protect everyone, and then began to recover.

This scene was seen by Tan Yi, and he remembered that the Xue family brothers and sisters also knew how to form formations, and they seemed to be able to summon various things, such as the summoned light curtain and the Triple Netherworld Gate, which had a good defense, and could also summon dragons to attack.

A long time ago, the formation used by the Emperor of the Three Kingdoms when he attacked the Nanwu Forest and fought with the three major demonic beasts summoned a giant with great power.

As soon as Tan Yi's consciousness moved, a memory appeared in his sea of consciousness, and all that was recorded in it was the cultivation of the formation. This was left to him by Wuji, in addition to the formation, there was also the method of refining weapons.

He refined the two memories into the sea of knowledge, and in an instant, he had a wealth of theoretical knowledge, as long as he practiced again, he would immediately become a formation master and a refining master.

Half an hour passed quickly, and the crowd continued on their way.

Hao Xin led the way in front, and along the way, they flew over several cities, their brows furrowed more and more tightly, and Lu Dongtian's face became even more ugly.

Those cities, everywhere in ruins, blood stained the earth, penetrated deep into the land. But there was not a single corpse in sight, as if there had been a massacre here, and the smell of blood was extremely strong.

"This must have been done by the demons of the underworld, so cruel, there are at least two million people in such a big city! We've passed through seven cities, and that's tens of millions! A friar looked disgusted.

"The smell of blood is still so strong, I'm afraid that the slaughter has not been long in coming. This kind of city should not lack masters, but it still can't resist, let's ......" a heaven-breaking monk muttered in a low voice, and suddenly a gaze fell on him, making him shudder.

He looked over, it was Lu Dongtian's gaze, and he quickly closed his mouth, not daring to say another word.

He felt that Lu Dongtian was angry with him, although Lu Dongtian's realm was inferior to him, but the true yuan quality of the two was very different, one was a heaven-level quality and one was a yellow-level quality, and it was not a problem for Lu Dongtian to defeat and teach him a lesson.

"Attention! There's a lot of Underground Demon Ahead! At this time, a middle-aged man, a monk with the highest cultivation, reminded.

This middle-aged man has the realm of Breaking the Heavens and Breaking the Triple Realm, and he has been in this realm for a long time, and his strength is slightly stronger than the other three Heaven-Breaking Triple Cultivators. His divine sense sensed that in a city ahead, the demons of the underworld were hunting humans.

Everyone stopped, not daring to approach, the underground demons who can slaughter the city will definitely not be weak, and the number will not be small.

The middle-aged man stopped as soon as he sensed the demons in the underworld, and if he got closer, he would be discovered by the demons in the underworld.

"Senior Sister Hao Xin, how far is it from the underground demon lair you explored?" Lu Dongtian looked at Hao Xin.

"It's less than a hundred miles."

"Let's hide our bodies, go around it, and make our way to the lair! They hunted and slaughtered men, and they must have prepared sacrifices, and they must have rescued my father before they sacrificed. Lu Dongtian became more and more impatient.

The rest of the people didn't want to meet the underground demons, and it would be best if they could save Lu Dongtian's father without being injured.

Tan Yi took a deep look at the city below that was slaughtered by the demons underground, sighed, and hid his breath.

Soon, everyone came to a grassland and followed Hao Xin to find a deep hole that was covered by the formation, this deep hole was two or three zhang in diameter, and it was bottomless.

"This is it, this is a relatively small passage, there are few underground demons in and out, and the strength is not strong, just suitable for us to infiltrate." Hao Xin said.

Lu Dongtian nodded and began to assign tasks. "Good. There are fifteen of us, leaving two Breaking Heavens and Doubles here to guard and send a signal if there is danger. Senior Brother Wu, Senior Sister An, please go to the front to open the way, Senior Brother Le, Senior Sister Chang, you are behind. The others followed me and Tan Yi down and went! ”

The person who is called Senior Brother Wu is the middle-aged man named Wu Huacheng. The other three are named An Ling, Le Zhensheng, and Chang Qian.

Whew...... Thirteen men jumped into the cave and moved quickly, leaving two of them to hide and stay there.

After moving for several miles, the passage became more and more wide, and the front suddenly opened up, and he came to a huge karst cave with a spacious space, where thousands of underground demons were resting, and the realm was not high, only the innate realm.

"Kill them all, and don't let them stand in the way of our retreat." Lu Dongtian was murderous and began to do it.

Wu Huacheng slapped out with a palm, and under the urging of Zhenyuan, a huge palm fell from the sky, killing hundreds of heads in an instant, and their bodies were slapped into meat patties, red and white mixed together and flowed out.

An Ling stretched out his hand and grabbed the void, the space squeezed violently, and hundreds of underground demons were crushed to death.

Others also took action, with supernatural powers, with the power of space, thirteen Heaven Breaking Realm powerhouses tortured and killed thousands of Innate Realm underground demons, it was as simple as eating and drinking, killing all of them in just a few breaths, and then moving on.

They passed through several caves in a row, and all the demons they encountered were from the innate realm, and the strongest was only a half-step Heaven Breaking Realm, even if there were more demons in the underground, they couldn't withstand the torture and killing of thirteen powerhouses.
