The King of Time and Space and Dragons was trapped in a heavy siege. In just a moment, several more mechas appeared around them. They were covered in scars, and black fog and black light poured out from the scars, causing the underground hall to fall into darkness and almost enclosed space.

"Come on, Blue Mountain Seal." Li Yuan shouted lightly, his will and the mecha were in harmony, and he quickly cut out eighteen swords. The sword was shining blue with fierce murderous intent, trying to create a gap in the encirclement.

The spark flashed, and just as the Longyuan Great Sword was about to break through, it encountered powerful obstacles.

"Buzz,buzz,buzz..."

Li Yuan looked in shock and saw that the Longyuan Great Sword was tightly bound by five circles of black fog, and black light leaked from the black fog, spreading to the sword body in the form of a blood vessel.

"What the hell?" Long Yuan's sword was invaded by black light, and there was always an ominous premonition. Li Yuan concentrated on his energy and shouted: "The black cube shocked me."

"Dangdang, Dangdang, Dangdang..."

The black cube caused the space shock and passed it to the Longyuan Great Sword along the arm of the Sky Dragon King. The sword body hit the black fog circle, making a crisp sound of ringing the bell. The black light that clung to the sword body suddenly paused, and black fog evaporated outside the sword body.

"What a difficult thing." Li Yuan madly increased the frequency of space tremor within the mecha's bearing range and transferred all the shock force to the Longyuan Great Sword, and only heard the "Dangdang" sounds constantly.

"Grandma, let's go. These black fog circles are rich in dark matter and produce a strange dark energy. Master, don't absorb them with the black cube. Their properties are very mysterious and cannot be understood." As Elizabeth reminded, the nearby mecha attacked Li Yuan. The King of Time and Space Dragon shook his arms and moved his shape and changed his position to avoid it.

I didn't expect that I would encounter such a risk when entering this underground hall.

With the loud "dang", the five black fog that bound the Longyuan Great Sword dissipated, and disappeared along with the black light that clung to the sword body.

"Use the Star-breaking Whisk Sword."

Li Yuan put away the Longyuan sword, took out the broken star whisk sword and swept it around. Immediately, countless lights collided with the black fog and black light, igniting Mars all over the sky.

With the sparks floating, the shadows shine.

"The number of enemies has increased again. Seeing thirty-five mechas, there are still things coming in the dark and cannot be surrounded." Li Yuan has rich combat experience. He made a quick decision to throw out the Star-Breaking Whisk Sword and open the mechas defense to the limit, not to destroy the enemy, but to destroy the surrounding dark matter enclosed environment.

"Boom"

After the dull sound, billions of starlight burst out and the light swept out. In an instant, a large section of haze around me was dispersed. The space that seemed to be completely closed just now suddenly appeared, and Li Yuan was waiting for this moment.

The King of Time and Space Dragon Steps slightly, as if it merged with the exploded starlight, quickly rushing out of the dark matter encirclement and escaping from the Heaven of Birth.

The good guy used the Star-Breaking Whisk Sword to break through, and even Li Yuan felt extravagant. The old Poison Yuan sword no longer exists. There are currently four sharp swords hanging on the top of the iceberg mountain of the Black Cube, Lei Yu Instant Killing Sword, Electric Vein Killing Sword, Chaos God Killing Sword, and Cause and Effect Destruction Sword.

The King of Time and Space and Heaven and Dragons rushed out of the encirclement and did not exit the underground hall, but continued to go deeper, because the exit of the hall had been blocked by the dark matter field and even spread to the surface.

Li Yuan entered the depths of the underground hall and found a deep passage. He was very careful. There were many weird things here, including broken and strange mechas, fog circles that could wrap around the Longyuan sword, and black light spreading to the sword body. It took a lot of effort to break free. It was definitely not a simple thing.

So many weird things show that the Yilin people hide big secrets here, so it is best to find out the truth.

At the moment, he could not use the Longyuan Sword, so he took out the Lei Yu Shun Killing Sword. Li Yuan was very skilled and brave, and drove the Space Dragon King to quickly rush into the passage.

On the way, they encountered that strange mecha again, but fortunately they were alone and failed to form a group of dark matter confinement areas.

In terms of sword speed alone, the King of Time and Space is much stronger than these weird mechas. As long as Li Yuan is not surrounded by them, it is easier to deal with it. Moreover, Lei Yu instant killing sword is powerful and can penetrate the fuselage in an instant, but no matter how hard you try, you cannot completely cut the mecha. It feels like a ball of sticky liquid after cutting into the body, which means that there is something else inside the mecha.

"It's weird, so weird, I've never encountered such a weird situation." Elizabeth actively collected data, and it is still impossible to guess the causes of these mechas.

"My God, should we thank these ghosts?" The King of Time and Space Dragon entered an underground hall again, with traces of battle everywhere, with rich space fluctuations remaining in the sky, and bright treasures scattered on the ground.

These "treasures" include silver scorpion tails, golden horns, purple jawbones, green eyeballs, and unique light cocoons, all of which are trophys left by the old terror Lord.

Judging from the traces left nearby, there has just been a very brutal battle here. The old terror lord and the ancestral beast legion responsible for guarding this place were wiped out, and the attackers must have been those strange mechas.

Li Yuan couldn't help but feel scared. Perhaps now was the weakest moment for those mechas, so he was lucky enough to escape the siege when entering.

The King of Time and Space and Heaven floated forward without touching his feet, and there was a pair of big hands behind him, grabbing "trophys" from the hall, making the hall dim immediately and losing the light of treasure.

"Hehe, the harvest is really good. Thirty-three semi-god treasures, ninety-eight rare materials, as well as a large amount of alien energy remaining in the silver scorpion tail and purple jawbone, as well as sixty-two top light cocoons. The key is to pick it up for free, this one I like the most." Elizabeth almost grinned her mouth to her ears, jumping with joy, and her face was like a daisy in bloom.

However, this was just the beginning, and then we walked through nine passages and eight underground halls, all of which were the same scene, with "treasures" everywhere.

The deeper you walk towards the passage and hall below, the more "trophys" you drop on the ground, and even five divine treasures with a faint smell of Yilin's universe were found, and the number of semi-god treasures increased to 500 in one fell swoop. I don't know how many old terror lords died here, and some silver scorpion tails and purple jaw bones that should have been left behind were broken, and black spots appeared on the surface of the fragments, which looked very terrifying.

"According to my speculation, we touched the city defense force when we siege the city, weakening the power to suppress the place. Those strange mechas seized the opportunity to break out of the cage and launched an attack on the terrifying lord who guarded the place."

Based on the remaining traces in the hall, Elizabeth launched the battle scene and said, "During the fierce battle, many terror lords were ordered to enter the ground. Their main intention was not to intercept the strange mecha, but to march deep into the ground. Something should attract them and make the Ilin people want to get it back at any cost. At this moment, we let the ancient giant beasts self-destruct on the surface, causing the passage to rise to the surface to collapse. The terror lord who took the lead did not receive subsequent support, and the entire army was wiped out."

"Well, this should be the case. Maybe these terrifying lords are close to success, but they failed at the last moment." Li Yuan nodded.

The battle traces were very obvious. There was no problem with Elizabeth's counter-redirected battle situation. After the terror came in, he was indeed fighting at all costs, which was much more tragic than attacking the ancient giant beasts.

Continue to go deeper, encountering thick black fog, and sinking into it, you can't even recognize the direction. Suddenly, a mecha appears, and a green light appears in both eyes, saying, "You are finally here, you dare to attack the young man who dares to attack the Tiancheng City

"Hey, are you?" Li Yuan was very surprised. There were normal mechas in this ghost place. However, there were many cracks on this mecha, and thick black fog overflowed from the crack, giving people a very dangerous feeling.

"I am the Holy King Goethe. When I assisted the three generations of demon emperors ascending the throne, I was captured here by the powerful existence of the Yilin people and suppressed for many years."

The sound from the mecha was very weak, and they said intermittently: "At first they wanted to study the evolution of our human mechas, but as the scouts of the Black Death Universe Sect, the old rival of the Yilin people, entered the virtual plain, they suddenly changed their research plan, captured many black dead species, forced them into the mechas, and used the human body as a container to carry out a very terrifying experiment.

The Yilin people discovered that the body radiation of a few mecha kings could trap black dead species and promote genetic mutations, and there was a certain probability that they would become a community that blends with each other. So they went on to conduct experiments intensifying their efforts to make the body and the mecha turn into geeks.

If the experiment is successful, the Yilin people will use humans to deal with the black dead species, so they have accumulated extremely strong strength in the virtual plain, but have not started the battle for a long time.

Until a few days ago, the experiment achieved the latest breakthrough. I guess they could no longer hold it in and had started a war against humans. Unexpectedly, when I was in a daze and about to lose consciousness, I could meet someone who was capable of challenging the main city of Yilin people…”

Before the other party could finish his words, Li Yuan suddenly set out a sword to attack. Almost at the same time, the Holy King who claimed to be Goethe also bombarded the mecha sword, and the lightning collided with the black light, shaking a piece of space.

"Little devil, how did you find out?" Goethe asked in a panic.

“How did it be discovered?”

Li Yuan sneered: "Haha, it seems that you have been closed here for a long time, which will make your mind less intelligent, or Goethe now is just a distorted experimental subject. You shouldn't have said so much, but you even put yourself in a very high position. When you develop to my level, will you care that you are the third generation of assistant ministers of the Demon Kingdom?

Speaking of which, I offended all the royal family in the Demon Kingdom. I was stupid and bold at that time and had good luck. Exploring the Six Emperor Mausoleums of the Demon Blood Star, Empress Andrea once bombarded me with the Jiuhuang Wheel. The powerful sword of time left by the Jiuhuang Wheel is still fresh in memory. If I hadn't lit up Qin Lanque's coffin and blocked it, I would have died.

There is also the old madman who burned out the prison. He was actually assassinated and suppressed by you.

I calculated the time span of your activeness and found that it was much longer than other sacred kings. Combined with your attainments in the time field, I guess you have a way to extend your life through the Mecha King with similar attributes. In this way, isn’t the Dragon King of Time and Space?”
