Before long, Su Mo found the source of that sound.
He fixed his eyes and saw two martial artists attacking a demonic beast.
There were a man and a woman in their twenties. The man was tall and handsome; the woman looked fair and beautiful, wearing a reddish dress.
To Su Mo's surprise, their cultivation arrived at the Lv 3 True Spirit Realm.
The beast that they were fighting against was a 10-meter-long and Class 4 Lv 3 Demonic Beast Leopard.
Obviously, they had completely lost their offensive stance and could not defeat the beast.
"Ling Ping. We can't win. Go! Go!" The tall young man yelled.
Having said that, they rapidly flew into the sky to escape.
However, the Demonic Leopard moved as fast as lightning. Within a second, it caught up with them and attacked their back with its powerful paw.
"Get away!" The youth angrily shouted out.
He turned back and split the paw. The dazzling saber radiance and the leopard's paw collided together.
Boom!
With a loud bang, the tall youth was hurled away and hit on the ground, which even made the ground crack.
Also, the beauty became panicked because of the unexpected attack. She hurriedly turned back and waved her sword to resist.
But the beast's strength was too powerful to resist. The beauty was also blasted backward and crushed on a five-meter-diameter tree.
Phfff!
She spat out a mouthful of blood.
Swish!
After it made the attack, the black Demonic Leopard approached them in a blink with inconceivable speed. It was going to kill them with its sharp paws.
"No!"
"Oh, no!"
They were frantic in despair. In fact, they just planned to hone their kung fu in the Devilcloud Mountains and never thought that they would die here.
At the crucial moment, an overwhelmingly sharp Sword Qi suddenly cut on black Demonic Leopard from far away.
Boom!
The Demonic Leopard roared. It had received many gaping wounds, so it had to knock back.
On seeing that the beast got wounded, the tall youth and beauty were shocked.
As soon as they looked back, they saw a yellow-robed young man, carrying a long sword.
Su Mo strode toward the two people after he repulsed the beast. Since he did not want to see the demonic beast eat two people, he decided to help them.
"You didn't run away?" Su Mo said.
Su Mo came over. The Demonic Leopard did not escape when it saw Su Mo, and it even released a cold and ruthless aura with great anger.
"Since you didn't leave, Go to hell!" Su Mo coldly said.
Su Mo moved like lightning towards the Demonic Leopard.
Awoooo!
The Demonic Leopard howled and rushed to Su Mo.
"Watch out!" The beauty shouted.
As soon as she yelled, she saw a sharp ray of sword radiance cracking the air and chopping the Demonic Leopard into two pieces.
"What?" The beauty was shocked and gazed at Su Mo in awe. This young man killed the Class 4 Lv 3 Demonic Leopard within a movement.
The tall youth stood up pathetically and also was stunned. Although they were talented in martial arts, they could not defeat the Demonic Leopard, while this young man, who just arrived at Lv 2 True Spirit Realm, could kill it in one movement.
After Su Mo killed the Demonic Leopard, he asked them, "Are you fine?"
They shook their heads and the beauty replied, "We're all right. It's just a scratch."
"That's good. Hopefully, we meet again someday." Su Mo nodded and was going to leave.
"Master, please wait a second!" At this moment, the beauty suddenly asked him to stay.
"What's going on?" asked Su Mo.
The beauty meditated for a while and then sincerely said, "Since Master had saved our life, Ling Ping wants to invite you to visit Mu Mansion, so I can express my sincere thanks to you."
The other man also echoed her suggestion and said, "My friend, please follow us."
Su Mo shook his head and disdainfully replied, "It's unnecessary. Perhaps we'll meet again one day."
Su Mo was eager to leave, so he didn't want to waste time.
The beauty didn't give up and she continuously said, "Master, Mu Mansion was located in Tongzhou City, 2,000 miles away. It won't take you too much time to arrive there."
"Tongzhou City?" Su Mo thought it over. Tongzhou City was the second largest city in Topsun Country, with millions of residents. He once heard of it.
He meditated for a while and finally agreed to her request. Since she had invited him quite warmly, it was impolite to refuse her.
Of course, Su Mo had his own plan. Originally, he decided to find a big city in Topsun Country, so that he could buy some Beast Souls.
Since they lived in Tongzhou City, it did not matter if he went there.
"Haha! Thanks. Let's go right now!"
The young lady smiled charmingly and spoke to the youth. "Brother Xu, we can return now."
The tall youth nodded.
After a short while, they flew to the sky and left the Devilcloud Mountains toward Tongzhou City.
On their way to Tongzhou City, Su Mo learned that the beauty was Mu Lingping. She is a Miss from the Mu family in Tongzhou City. The tall man called Xu Xinghan, he was the son of Guest Elder of the Mus. He could also be regarded as a disciple in the Mus.
Mu Lingping and Xu Xinghan were rare geniuses in the Mus. Their cultivation had both arrived at Lv 3 True Spirit Realm.
Su Mo also sighed. Even though the two had great kung fu talent, which even could compare with the Four Talents of Skymoon Country, their combat force was much worse than Four Talents of Skymoon Country.
For Su Mo and the two people, who were the experts in the True Spirit Realm, they only spent four hours to reach the city, which was 2,000 meters away.
About four hours later, a big and beautiful city came into Su Mo's sight.
"Tongzhou City is bigger than the Imperial City in Skymoon Country." So Mo thought. "The developed country was so great that Skymoon Country can't compare with it."
Su Mo entered Tongzhou City with Mu Lingping and visited the Mu family's mansion.
He had to say, the Mus was a powerful family. Their mansion sprawled over tens of miles.
In a gorgeous yard, Su Mo, Mu Lingping, and Xu Xinghan sat nose to nose.
"Master Su Mo, may I drink a toast to you and thank you very much for saving our lives?" Mu Lingping asked.
She raised her glass and swallowed it neat.
"Haha, you're welcome!" Su Mo also drunk it out.
"Brother, you look very young, but your martial arts strength is unexpectedly strong. You're extraordinary indeed!" Xu Xinghan smiled and said, "Brother, are you going to the third prince's banquet?"
"The Third Prince's Banquet?" Su Mo seemed confused.
"Well, bro, didn't you know?"
"The third prince in Topsun Country invited all celebrities to visit Imperial City. Now, a lot of geniuses are on the way to Imperial City. Amongst them are the talents from other countries nearby." Xu Xinghan said. "The third prince ranked number 49 in List of Top 100 Talents. Also, he's well-known in Hong Domain. It's widely said that he also invited many martial arts experts on the List of Top 100 Talents."
It surprised Su Mo. "The third prince in Topsun Country is actually on the List of Top 100 Talents."
"Master Su Mo, we're going to Imperial City tomorrow as well. How about visiting with us?" Mu Lingping invited Su Mo to join them.
After a while, Su Mo nodded. He thought it would be better to see the real strength of these talents, who ranked on the List of Top 100 Talents so that he could know them better.
