Zhang Luochen didn't say anything else. He continued to control his game characters and continued to fight.

Untiredly, he bombarded the surrounding monsters with lightning. Thunder, Thunder, or Thunder, this magician only learned from level 60 is the most suitable for monsters to kill. With the support of the thunder method of the legendary weapon Cang Lei Sword, the dense monsters followed one after another, and fell in pieces under the bombardment of lightning.

A few fish that were not dead with residual blood were also killed by the guardian heavenly soldiers he summoned.

The blue-return effect of Beiming suit and the bundle of big blue and red in the bag made him not need to stop and recover, but he was tirelessly harvesting his experience.

However, even if the experience of less than 1% in the end is still an astronomical figure. After an hour and another hour, the last square of the experience bar seems to never be filled.

Zhang Luochen fought from the 29th floor to the 32th floor, then returned from the 32th floor to the 25th floor, then returned from the 25th floor to the 32th floor, killing monster corpses all over the world, constantly turning into white light of experience.

Chen Feng yawned and felt as if he was about to fall asleep. He poured himself a third cup of coffee and glanced at Zhang Luochen, but found that the other party was still energetic, his eyes seemed to be glowing.

Finally, as the experience value increases, the last bit of the experience bar is filled.

At the moment of upgrading, dazzling golden light filled the screen. I saw the golden light rising from the body of the "Yun Luochen" on the screen, the fairy aura rose, and nine dragon-shaped phantoms circling around him and danced around him. Then the protagonist disappeared in the air. Such exaggerated upgrade effects made both of them feel energetic in an instant.

"Advanced?" Chen Feng asked in disbelief.

"That's right, it's upgraded." Zhang Luochen replied, but his face was surprisingly calm.

"Haha, that's great! Hurry up and see what's behind that door."

Zhang Luochen shook his head, "No hurry."

As he said that, he first changed the Beiming suit, the spiritual jade, the Cang Lei sword used to level up, and the Taishang Tianzun suit with better attributes, the Tianlong Seal and other equipment, and his weapons were replaced with the artifact-level Tongtian Staff.

Then he opened a portal to return to the city, opened his own warehouse, and took out all kinds of elixirs, talismans, and magic weapons from it, filling his backpack with one breath.

Then return to the Tower of Heaven and head straight to the 33rd floor.

The thirty-third floor of the Tower of Tongtian is the only one in this tower that does not kill monsters. The empty top gives people an extremely quiet feeling. Seven-colored clouds are surrounded by the top of the tower. The gaps between the clouds can also be seen vaguely in the earth under the tower.

At the edge of the tower, a long bridge passes through the clouds and extends into the void in the distance. The mysterious gate leading to the unknown stands at the end of the long bridge, as if leading to the world outside the sky.

He controlled the character to come to the door. Zhang Luochen first filled his mana and life, then opened the package and took all the prepared elixirs, including Penglai Immortal Medicine, Immortal Golden Pill, Immortal Secret Medicine, Divine Walking Pill, Vajra Pill, Fire-Breaking Pill, Lingquan Immortal Wine, Secret Dragon Meat Pie... Anyway, all of them can provide the gain effect.

Then he added all the gain spells he could add to himself. Seeing more than a dozen buffs layered on top of his head, Zhang Luochen nodded with satisfaction and pointed to the door.

[System tip: Your power is enough to open the door. Do you want to open this door?]

Choose to open the door. As the door slowly opened, Zhang Luochen and Chen Feng's hearts rose.

Behind the gate was a dark hole. Zhang Luochen pointed at the hole, and his eyes immediately became dark and he had entered another space. At this time, he was standing in a void, surrounded by a dark universe background dotted by countless stars. He explored around and found that there were air walls on the upper, lower and left sides, and only the right side could walk.

He walked straight towards the void on the right, Zhang Luochen walked carefully. Although he was already level 99 and was wearing magical clothes, it was impossible for him to encounter any danger again, but considering that this was a map that no one had ever come to, he had to become cautious.

Chen Feng's heart was pounding when he looked behind. He glanced at Zhang Luochen, wondering how the other party could be so calm.

In fact, Zhang Luochen was not calm. The secret that had been exploring for ten years was finally revealed. There had been waves in his heart. However, the most amazing thing about him is that no matter how complicated emotional changes there are in his heart, he can always remain calm on the surface.

He didn't encounter any monsters or any mechanism along the way, which made him feel relieved and a little disappointed.

At the end of the void, an old man sat cross-legged on a broken star. His name was [Mysterious Old Man]. This mysterious old man was wearing a tattered robe, his hair, beard, and eyebrows were all white. It was not simple at first glance. There was another stone door behind the old man.

Zhang Luochen first clicked the stone door [System prompt: This door is sealed by an invisible force, and you cannot open it.]

Then he clicked on the old man again, but a conversation appeared.

Mysterious old man: "Thank God, someone finally came here. I have been waiting for you for a long time. I thought no one would ever come. The people who trapped me here said that one day someone would come here. I didn't expect it to be true. Tell me, young man, what are you trying to do when you come?"

There are four options below the dialog box:

Option 1: I'm here to kill you.

Option 2: I'm here to save you.

Option 3: Who are you?

Option 4: Where is this place?

Seeing these options, Zhang Luochen's face became solemn. In the game Legend of the Three Realms, there are many options that you can't regret if you choose the wrong one. His next choice is likely to determine whether his hard work in the past ten years is valuable.

He thought for a while and passed the first two directly. As for the last two, Zhang Luochen decisively chose the fourth option.

Generally speaking, the option with the greatest risk and the greatest benefit is usually the last one.

Mysterious Old Man: "You want to know where this place is? This is the entrance to another world, and I am here to prevent something from coming from that door."

Four more options appear below:

Option 1: Who asked you to stay here?

Option 2: Where does it lead behind the stone door?

Option 3: What will come out from behind that stone door?

Option 4: What does this matter have to do with me?

Zhang Luochen did not hesitate too much this time. It was obvious that the fourth option was correct. After all, no matter what hidden plot or background story there was in the game, whether it was related to him was the most important thing.

He chose option 4.

Mysterious old man: "This matter has a lot to do with you. Those who once trapped me here told me that maybe someone would want to go through this stone door and go to other worlds to take risks. Of course, I think this is unreasonable. Who would want to go to a completely unknown terrible world? Those who trapped me here told me that if someone could open the door outside and run in, then most of them would be the case. If someone like this comes, I need to open the door and let him go."

"Of course, if the person who came did not want to enter that door, he could also ask for other rewards. Those people left three things, one was said to be the strongest secret book in the world, one was said to be the strongest weapon in the world, and a Qiankun bag containing endless money.

So, do you want to enter the door? Or do you want a reward?"

Four more options appear below:

Option 1: I want the strongest secret in the world.

Option 2: I want the strongest weapon in the world.

Option 3: I want endless money.

Option 4: I want to enter that door.

Zhang Luochen naturally chose the fourth option. Now there are only a few people in this game. I don’t know when I will be closed. Skills, equipment, or game coins have no value at all.

The fourth item is likely to open a hidden game map, which is something truly valuable.

The old man scratched his head, "It's really hard to understand that you really want to enter the door. You know, there is an unknown danger waiting for you behind the door. Maybe you will die. And because the rules of the two worlds are different, if you enter that world, your cultivation will disappear and you must start over. Are you sure you want to enter?"

Option 1: Yes, I want to go in.

Option 2: I think I'd better change the reward.

It was so long-winded. Zhang Luochen thought, and chose to go in again.

"Okay, you chose this yourself, don't blame me for not reminding you." The old man said, pushing the stone door open with force, revealing the entrance of a passage. The white light at the entrance was spinning like a vortex. I don't know where it leads, Zhang Luochen went a little towards the door without hesitation.

The vortex immediately spun quickly, and his game character's body gradually twisted and was sucked into the vortex. Zhang Luochen was immersed in his sight, and suddenly felt a powerful suction force coming towards him, as if the vortex was about to suck him into the screen.

What the hell is it! Zhang Luochen was shocked now. He subconsciously wanted to struggle, but the suction was so huge. Zhang Luochen felt his consciousness dazed in a daze. In the blink of an eye, he was sucked into the screen, spinning, gradually overlapping with his game characters, and finally sucked into the vortex together and disappeared.

Only Chen Feng was left looking at the empty chair in front of him in amazement. The coffee cup in his hand fell to the ground, and the coffee flowed all over the floor.
