Douluo: Succubus at the beginning, Bibi Dong was ruined!.

Su Mu originally planned to tell Ning Rongrong yesterday, but seeing Ning Rongrong's cheerful look, she still didn't say the words.

Su Mu packed everything early in the morning.

Su Mu quietly walked into Ning Rongrong's room. Looking at Ning Rongrong who was still sleeping, Su Mu raised the corners of her mouth slightly and looked at Ning Rongrong affectionately.

Su Mu walked gently to the bed and covered Ning Rongrong with the quilt that had been kicked aside.

Then Su Mu took out the last letter from the soul guide and placed it on the bedside table.

After doing all this, Su Mu's eyes were on Ning Rongrong again.

After watching for a few minutes, Su Mu bent down slightly, kissed Ning Rongrong's forehead gently.

Then Su Mu no longer hesitated and gently left Ning Rongrong's room.

When Su Mu arrived at the back mountain, Sword Douluo was already waiting here.

Seeing Su Mu, Sword Douluo didn't say anything. He directly stretched out his hand to grab Su Mu and took him flying.

Sword Douluo's speed was very fast. From Su Mu's perspective, the wind was all around him, making him unable to open his eyes.

But fortunately, Su Mu's physical fitness has improved a lot now, so resisting these is not a problem.

Three days later, Sword Douluo stopped.

Sword Douluo put Su Mu down. Su Mu stumbled and almost lost his balance. After all, he had been flying for so long.

During the three days, I only stopped a few times to eat something. The rest of the time, no matter day or night, I was pulled by Sword Douluo to fly in the sky.

Fortunately, Su Mu quickly adjusted and did not fall to the ground.

"This is it. I haven't been here for a long time."

Sword Douluo looked forward, a little melancholy, and said something full of complicated emotions.

When Su Mu heard Sword Douluo's words, he also raised his head and looked forward.

As Su Mu looked up, he found that this was a vast field, and the air was filled with a mysterious energy.

There are some ruins of some buildings made of unknown materials in front of them. The only thing that can be seen is that they must be from ancient times.

Su Mu looked carefully and found that the building in the center looked like an altar, and it was still emitting a soft light.

In the light, Su Mu could vaguely see a seemingly illusory door, which seemed to connect to another brand new world. The door is engraved with ancient runes and mysterious patterns, which make people wonder.

Before Su Mu could ask, Sword Douluo spoke first,

"Yes, that altar is the entrance to the secret realm, and I discovered it accidentally."

Saying that, Sword Douluo handed Su Mu a jade token,

"Go ahead, I'll wait for you to come back. I stayed there for six years. I don't know how long you will stay. When you come out, crush the jade token and I will come to pick you up."

After hearing Sword Douluo's words, Su Mu took the jade token, nodded, and walked towards the altar.

When Su Mu approached the altar, she found a wonderful sense of tranquility permeating the air, as if the whole world had stopped at this moment.

Su Mu stood in front of the altar, facing the mysterious door, full of curiosity and expectation. This will be the gateway to the unknown!

Su Mu saw another "stone pillar" in front of the altar. There were five recessed fingerprints on the top, which happened to be the shape of a palm.

Sword Douluo's voice also sounded in Su Mu's ears,

"Put your right hand up and it will detect your talent. Only those who are qualified can enter the secret realm."

Su Mu naturally chose to trust Sword Douluo and pressed his right hand up, perfectly fitting the depression on the "stone pillar".

The moment he pressed it completely, Su Mu felt a force entering his body. The kind of soul power was unlike anything Su Mu had ever felt.

Before Su Mu could experience it carefully, the mysterious power disappeared.

Immediately afterwards, a powerful suction force erupted from the illusory door on the altar, sucking Su Mu in before Su Mu could react.

Sword Douluo saw this scene and nodded. He was not surprised at all. If Su Mu couldn't get in even with his talent, I'm afraid no one would be able to get in.

Sword Douluo did not stop. After confirming that Su Mu had indeed entered the secret realm, Sword Douluo directly took off and left.

……

Dizzy, this was Su Mu's first feeling.

The moment he was sucked into the secret realm, Su Mu felt a very strong sense of dizziness.

When Su Mu recovered, she found that she was down to earth.

There was so much fog all around that it was almost impossible to see clearly even one meter away.

Su Mu directly put on a defensive posture and summoned Xuanyuan Sword. Although soul power cannot be used here, martial spirits can still be summoned.

Su Mu held the Xuanyuan Sword and looked around cautiously.

……

Three days ago, Ning Rongrong woke up and found the letter Su Mu left for her on the bedside table.

Ning Rongrong looked at the four words "Rongrong personally" on the envelope. For some reason, although she hadn't read the content yet, Ning Rongrong felt empty in her heart.

Ning Rongrong stopped thinking and opened the envelope in her hand.

"Dear Rongrong, by the time you read this letter, I should have already left..."

When Ning Rongrong saw the beginning, she couldn't help but shed tears. She felt her heart hurt.

But when Ning Rongrong read the entire letter, she burst into tears and laughed.

At first, just reading the beginning, she thought Su Mu had left without saying goodbye, but after reading it, she realized that Su Mu had just gone to the secret realm to practice.

"Hmph! How dare you leave without saying goodbye. I will make you look good next time I see you!"

Ning Rongrong returned to her arrogant look, and only the tears on her face showed what had just happened.

But in an instant, Ning Rongrong's face showed a lonely look.

"I'm really not used to not having Brother Su Mu..."

Sometimes, a relationship doesn't need to be accompanied day and night to warm up, and missing someone sometimes makes people realize their true emotions.

……

Wuhun Temple.

Bibi Dong looked out the window. In her hand was the letter she had just received. It was a letter from Su Mu's brother to her.

"Brother Su Mu, just wait a little longer. It's almost time. You can go home soon..."

Bibi Dong whispered something, then carefully folded the letter in her hand and placed it next to her. There was also a strange talisman there.

At the same time, two other people from Wuhun Palace also opened the letter. After reading the letter, they couldn't come back to their senses for a long time.

After Qian Renxue and Hu Liena collected the letters, they devoted themselves to cultivation more resolutely.

……

In the secret realm.

Su Mu was fighting a transparent humanoid creature.

Sword Douluo told him that the greatest opportunity in the secret realm was this creature called "Sword Spirit" by Sword Douluo.

Su Mu discovered that "Sword Spirits" are creatures with no intelligence or soul power, but they can move with swords.

Moreover, "Sword Spirit" uses a complete set of sword moves. Although it is not very exquisite, it still has some merits.

Su Mu fought with the "Sword Spirit" with ease, blocking while studying the moves of the "Sword Spirit".

Finally, after Su Mu thoroughly studied and understood the set of sword moves of this "Sword Spirit", he swung the Xuanyuan Sword in his hand and killed the "Sword Spirit".

After the "Sword Spirit" was killed, it did not disappear completely, but became...
