The entrance to Dahan's underground world is located deep in the backyard of the imperial palace. It is a black hole with a diameter of about two hundred meters.

According to Liu Jingtian, this place was once a hill covered with colorful flowers. It was extremely beautiful and was a major attraction in the palace.

When I was a child, a group of princes, princesses and princes loved to play here.

No one knows that this is the entrance to the underground world, and they never know that there is an underground world under the palace.

On the day when the three-tailed fat man, the leader of Tianxuan Xingmai Patrol Heaven Hall, wanted to take away Liu Jingxuan by force, the Human Emperor only told his son and daughter this secret while fighting for his daughter.

And let them follow the map to find the dragon vein. If they succeed, they can hope to become the top existence.

Unfortunately, only Liu Jingxuan escaped in the end, and everyone else was captured. The emperor of the Han Dynasty, the prince, and many others died in the battle.

Now when I visit my old place again and see the devastation and the changes in things and people, Liu Jingtian, Liu Xiner, and the great Han Martial Saint are all filled with sadness and can't help crying.

"The Han royal family are really a group of bloody people. They would rather die than hand over the Ninth Princess."

Xiaoxiang sighed in her heart.

She couldn't help turning her head to look at the young man next to her, and murmured: "Master, I know you are also such a person, that's why you accepted Liu Xiner as your disciple."

"The underground world is complicated and the space is limited, which is not conducive to the movement of airships. Everyone, please come on the flying carpet."

Lin Yu put the starship into the belly of the mecha golden monkey, then took out a holy weapon void blanket with defensive energy, and asked the lion's roaring cloud to activate the true energy to make it bigger.

The next moment.

A ten-meter-long square flying carpet was suspended in the air, shining brightly and full of mystery.

A group of people stood on it, and then, under the control of Shixiaoyun, rushed towards the dark cave entrance.

Because the flying carpet has its own light, you can still see the surrounding environment even if you enter the dark underground. When you first enter, it is just a vertical downward passage. Except for the special earthen cave walls, there is only a cold atmosphere around it.

After descending about a hundred kilometers.

The space suddenly opened up and there was even light.

This place is like a Gobi desert, with a radius of thousands of miles, a piece of red land, no grass growing, only gravel on the ground, and endless silence.

There are many huge volcanoes on the earth, emitting red flames, and the nearby sky seems to be ignited, turning red.

The entire space is also illuminated by the presence of the volcano.

"This is different from the underground world of Daxia. It's like a huge space. Was it opened up by Emperor Yan and Huang to seal away demons? Are those demons in the volcano?"

Looking at the volcanoes, Lin Yu felt curious in his heart.

His consciousness extended for three thousand miles and he did not see the end of this underground world. He was amazed by the vastness of the space.

"Oh, it's been so many days, I don't know if Jingxuan has been killed."

Liu Jingtian was full of sadness, he was afraid of getting this unacceptable result.

"Isn't there a prisoner present? Just ask him."

Lin Yu turned to look at the silver rat man who was studying the little mecha golden monkey.

"Er Shuzi, stop tinkering with mechas for now, tell us what's going on underground and how many accomplices do you have?"

The big yellow dog kicked the silver rat man in the butt.

"I……"

The silver rat man turned his head, his face was red and swollen with anger, and his fists were clenched, thinking that he was also a sect leader in the Xuanhuang Realm, and he had never been so insulted that he almost fought.

But thinking about the consequences, he gave up and began to recount some of the information he knew.

Through his narration, Lin Yu roughly obtained some information about the underground world.

This place is like a folded space, but it is in a semi-integrated state with the space of the Guangyuan Domain. Unlike the remaining realms such as the Soul Palace, Demon Emperor Realm, and Death God Abyss, it does not have its own world rules.

The underground world is eighteen thousand miles long from east to west and nine thousand miles wide from north to south. The territory is extremely vast, and the vast land here is dotted with volcanoes.

It is precisely because of the existence of many volcanoes that they have not caught Liu Jingxuan these days, because the flames of volcanoes have a sealing and corrosive effect on spiritual consciousness, and some volcanoes can even devour souls.

This has also put their progress in arresting people on hold.

As for the trace of the dragon vein, they didn't even see the hair. They could only hope to find Liu Jingxuan and follow the map to find the dragon vein.

When Liu Jingtian learned that his sister had not been captured, let alone dead, his face showed a look of relief, but immediately he became filled with sadness. How was he going to find his sister?

"Do you know where my aunt Liu Jingxuan is now?"

Liu Xiner asked the silver rat man in a soft voice.

Silver Rat Man said: "The people who are looking for Liu Jingxuan are all sent by the three-tailed fat man. We just came to help and take away the dragon vein.

Not long ago, it seems that the three-tailed fat man's men came to announce that they had discovered Liu Jingxuan's whereabouts.

But because we were coming to ambush you, we didn’t rush there, but sent some people to arrest you.”

"So, the three-tailed fat man and the others already know the specific location of my sister."

Upon hearing this, Liu Jingtian suddenly became nervous and worried.

Liu Xiner's heart tightened and she lost her voice: "Isn't the Nine Emperor Gods in danger?"

"We have to find Liu Jingxuan as soon as possible, Daxian, everything depends on you."

Lin Yu also knew that the matter was urgent. If the Moth Fireman, Phoenix-Winged Pterodactyl, and Three-tailed Fat Man were the first to find the dragon's veins, then everything would be in vain.

"Do you two have anything on your body that Liu Jingxuan has come into contact with before, such as bracelets, sachets, etc."

The big yellow dog looked at Liu Jingtian and Liu Xiner.

"I have."

Liu Jingtian immediately took out the jade pendant given to him by his sister and said, "This is the jade pendant my sister once wore. She gave it to me when she entered the underground."

"Okay, let's see how this great immortal displays his magical power and instantly locates Liu Jingxuan's position."

The big yellow dog took the jade pendant, put it on the dog's nose, sniffed it, and then began to meditate with his eyes closed.

About three minutes later, with everyone watching, its eyes suddenly opened and it said loudly: "I know where she is."

Hear the words.

Liu Jingtian and Liu Xiner were both surprised and delighted. This efficiency was too fast. It only took three minutes for them to know the specific location.

"Tch, it must be bragging."

The silver rat man murmured in a low voice, he didn't believe that this dog's nose could be so strong. Thousands of people on his side searched for seven or eight days but couldn't find it, but this dog could be found in three minutes? Who are you kidding!

Wo Xiaoqiang and Shi Xiaoyun looked at the big yellow dog in shock. They didn't expect that this plain-looking native dog could have such abilities. They felt a little doubtful in their hearts.

And Lin Yu and Xiaoxiang have no doubts about the big yellow dog's ability. After all, this is not the first time.

"Liu Jingxuan is in the northwest, follow my command and move forward."

There was a strange light in the big yellow dog's eyes, and he stretched out a paw and pointed into the distance.

"Master of the Lion Hall, listen to the Immortal and move forward at full speed. We must arrive as soon as possible."

Lin Yu ordered.

"yes."
