Warrior's Promise

When danger came close, Su Mo dodged without thinking.

However, the next second his body fell into the dark.

Su Mo was under a huge bouquet of black flowers earlier, which suddenly bloomed and devoured Su Mo.

In the dark, Su Mo was beaten by sawteeth severely.

But these teeth couldn't harm Su Mo at all.

"Break it!"

Su Mo shouted quietly and his Dark Force flooded out in all directions.

Bang!

The huge black flower collapsed and broke into tons of black pieces.

Su Mo's figure reappeared, perfectly unharmed.

"I didn't think this plant could attack!"

Su Mo looked surprised. This black flower couldn't really hurt him but was actually pretty powerful. It could possible kill a Lower Martial King with ease.

Quickly Su Mo left this place and marched on.

To not make any noise, Su Mo was more careful, staying away from all plants.

After flying in this underground world for less than half an hour, Su Mo avoided more than a dozen patrol units of the Netherworld Devil Sect and finally located the main gate of the Netherworld Devil Sect.

In his sight, there was a long stretch of building complexes.

These buildings were arranged into four identical cities, standing in a line.

The four cities were all built with black boulders, big enough to accommodate one million people.

"Cold Ghost City, Cold Yin City, Cold Corpse City, and Cold Devil City!"

Su Mo hid afar, discovering a name on top of the city gate of each city.

He realized these four cities were the Netherworld Devil Sect's four devil halls.

The Central Continent was known for four devil halls. Here were four cities.

Su Mo could clearly feel his Natal Spiritual Sword inside the Cold Yin City's Shady Hall.

However, he had no idea where Hong Qingxuan was.

Su Mo took a moment to think and decided to look for Hong Qingxuan first. He could retrieve his Spiritual Sword whenever he wanted but it might be the only opportunity for him to save Hong Qingxuan.

His first problem was to get in the city.

He had already changed his appearance and clothing but his aura was completely different from anyone of the Netherworld Devil Sect.

Su Mo needed a way to sneak in not by force.

The Netherworld Devil Sect had many powerful fighters, including an Emperor-to-be. If he met force with force, he would have no chance of saving Hong Qingxuan.

After thinking for a moment, Su Mo finally got an idea. He would enter the city from underground.

The only thing that bothered him was if there was a City-Protecting Formation for each city.

If the city was secured by a City-Protecting Formation, it wouldn't be possible for him to enter from underground.

A moment later, Su Mo was surrounded by his Dark Force. The ground under his feet perished and he went down completely.

Su Mo advanced towards the city that housed the Yama Hall, the head of all halls of the Netherworld Devil Sect. Hong Qingxuan was very likely kept in the Yama Hall.

Su Mo performed the Triple Breathing Technique and suppressed his aura as much as he could, trying to cover up everything.

Moments later, he sneaked under Cold Devil City and then prowled up slowly.

Soon, Su Mo's body popped out from a hidden corner of Cold Devil City.

Everything went well. There was no city-protecting formation. He entered Cold Devil City with ease.

Su Mo began to search thoroughly in Cold Devil City with his spiritual consciousness.

The city accommodated more than half a million members of the Netherworld Devil Sect.

After searching throughout Cold Devil City, Su Mo couldn't find Hong Qingxuan.

There were several palaces he didn't enter because of the horrible auro coming out.

It was a sign of a very powerful martial artist.

Su Mo stayed away so the enemy wouldn't be alerted.

He searched the other cities in the same way but scored nothing.

"Where is she on earth?" Su Mo's brows knitted tightly. There were places he didn't check in each city and Hong Qingxuan could be kept anywhere.

However, once he explored with his spiritual consciousness, those mighty fighters would know.

"Catch someone and ask. It would be great if I could get Huangfu Qing!"

Su Mo lowered his voice. He was inside the city of the Shady Hall and Huangfu Qing belonged to the Shady Hall.

By chance, his Natal Spiritual Sword happened to be in Cold Yin City as well.

Su Mo calmed his mind and followed the induction in his heart towards his Natal Spiritual Sword.

He walked through streets and alleys and avoided many of the Netherworld Devil Sect.

Before long, Su Mo was close to a tower of four levels, made of grey and white rocks.

Standing not far from the tower, Su Mo watched quietly like a ghost.

"Interesting!" Su Mo couldn't resisting grinning as he felt a very familiar aura inside the tower.

The aura belonged to Huangfu Qing.

It seemed that Huangfu Qing was in possession of his Natal Spiritual Sword.

"Good. I'll capture Huangfu Qing and force him to tell me where Qingxuan is!" Su Mo made up his mind.

Su Mo's body flashed and he reached the front door of the tower.

Knock, knock!

Su Mo raised one hand and knocked gently at the front door of the tower.

He wasn't very concerned that Huangfu Qing would find out who he was. He had changed his appearance and covered his auro. Huangfu Qing wouldn't be able to recognize him right away.

Before his identity exposed, he believed he could defeat him.

However, ten breaths passed but there was so sound in the tower.

"He's not here?" Su Mo narrowed his eyes. His Natal Spiritual Sword was in the tower but Huangfu Qing seemed away.

No wonder Huangfu Qing's auro was so weak. He wasn't in.

It was even better. Su Mo decided to wait for gains without pains inside the tower.

He pushed open the front door and entered.

After closing the door behind him, Su Mo glanced across the tower.

There was a living room on the ground floor, several bedrooms on the second, a pill refining room on the third, and a practice room on the top floor.

There was no one inside. Su Mo entered the practice room where he found his Natal Spiritual Sword.

Inside the practice room there was a stone desk, on which there was a huge silver iron basin half full of some green liquid.

His Natal Spiritual Sword was soaked in the liquid.

"What liquid is this?" Su Mo felt puzzled. He looked for a long time but couldn't figure out what this green liquid was.

Su Mo carefully took his Natal Spiritual Sword out of the liquid and put it into his storage ring.

He sat cross-legged in this practice room, waiting patiently for Huangfu Qing's return.

Su Mo was not practicing because he didn't want his aura to leak which would reveal his existence.
