I am in Ultra: I became the strongest Leonix by opening blind boxes

Perhaps sensing the movement outside, the evil energy in the pyramid seal began to riot, hitting the golden seal barrier like crazy.

"Did you find me? How interesting..."

Seeing this scene, Duanmu Yu was also a little surprised. It seemed that the evil energy from another world was quite alert.

But it was in vain. Although the effectiveness of the pyramid barrier had been decreasing, a lean camel is still bigger than a horse. This evil energy could not break through the seal for the time being.

"Come on, let me see how powerful this so-called forbidden technique of the Land of Light is! System, use the one-time skill card Ultimate Cross Barrier!"

[Beep! The one-time skill card Ultimate Cross Barrier has been unlocked! ]

Ignoring the riot of evil energy, Duanmu Yu's mind moved, and a golden card in the space on his body flashed and disappeared on the spot.

Then a golden ball of light flew out from Duanmu Yu's energy timer and arrived at the top of the pyramid seal in the blink of an eye!

"Buzz!"

Suddenly, the light became brighter, and the golden light ball on the top of the pyramid seal projected four rays of light shining with extraordinary aura in the shape of a cross.

Under the shocked gaze of the Youlian witch, the four rays of light gradually condensed into the shape of a giant of light, with red and silver colors and a body cast like steel. The aura emanating from each giant of light was incomparably holy and vast!

They are the first generation Ultraman, Ultraman Seven, Ultraman Jack, and Ultraman Ace among the Ultra Brothers!

In Duanmu Yu's perception, even though they were just phantoms, the aura of the four Ultra Warriors was still extremely powerful, and each of them was a strong man above the mid-level A-level with a solid foundation!

If the four Ultra Brothers work together, they can even fight against quasi-S-class super powers!

"Giants from other worlds? Although these four giants are not super ancient warriors, the aura of light and holiness on them cannot be faked. They are definitely the best in the light camp. Why can Dark Mephisto control them?"

Gazing at the majestic figures of the four Ultra Brothers, the Witch Youlian began to doubt, "Could it be that he really came to seal the darkness?"

Not noticing anything unusual in Youlian's expression, Duanmu Yu looked at the Ultra Brothers who had completely condensed their bodies, and secretly gave the order to start sealing.

After receiving the order, the four Ultra brothers crossed their arms in front of their chests, and the vast light energy around them surged, condensing a layer of dazzling golden stripes on the four Ultra brothers. At the same time, four dazzling light pillars rose up, illuminating the entire pyramid seal!

Afterwards, the four Ultra brothers stretched out their hands to both sides, and a vast beam of energy light shot out from each hand. Soon, the energy beams in the hands of the four light giants intertwined together, forming a square shape that surrounded the pyramid seal!

A mysterious wave spread out from the bodies of the four Ultra Titans, and circles of energy ripples spread out.

As the energy ripples spread, countless lines appeared on the surface of the pyramid seal, and then it shattered under Youlian's horrified gaze. Countless golden seal fragments scattered and were absorbed by the Ultra Brothers' energy beams.

As the seal of the pyramid shattered, the evil aura surging inside rushed into the sky like a wild horse breaking free from its reins, instantly covering the entire Luluye Island.

At this moment, the Ultra Brothers retracted their arms and placed them in front of their chests, and shot energy beams that had absorbed the pyramid seal fragments into the air. Four energy beams converged at one point!

"Boom!"

With a loud bang, the sealing mechanism of the Ultimate Cross Barrier began to act. The golden sealing energy spread out from the center, and powerful energy waves instantly covered the entire Luluye ruins.

At the same time, an extremely huge circular energy seal barrier with a cross engraved in the center slowly took shape!

As the Ultra Brothers changed their gestures again, the ultimate cross barrier fell like a huge mountain, pressing heavily on Luluye's ruins!

"Bang! Boom! Boom!"

A series of dull noises were heard, and the walls and rocks around the Luluye ruins were all cracked. Countless bottomless cracks were scattered around the ruins, as if they were about to collapse.

The evil energy that was active in the Luluye ruins was suppressed in an instant!

"What a terrifying...sealing energy!"

You Lian's eyes were filled with shock and curiosity, and she said in surprise: "This kind of sealing power is something I couldn't achieve even at my peak 30 million years ago!"

Although You Lian had already anticipated the power of the Ultimate Cross Seal, she still couldn't help but be shocked when the Ultimate Cross Barrier descended on the Luluye ruins!

"This sealing skill is called the Ultimate Cross Barrier, and it is a forbidden technique even in the Kingdom of Light!"

Duanmu Yu slowly floated to Youlian's side and explained calmly, "This forbidden skill is extremely powerful. It can completely seal the space where the seal is located at 360 degrees. It will not be unlocked unless it is irradiated with negative energy of the same level waveform. This move consumes a lot of energy. The four Ultra Warriors used it once. The horrible consumption made them lose their ability to transform. After 20 years, they have only recovered a little bit of vitality."

"Ultimate Cross Barrier? Kingdom of Light? So you are not creatures of this universe?"

After hearing Duanmu Yu's explanation, a look of understanding emerged on Youlian's pretty face, and she thought to herself, as expected.

"Hmm? I didn't expect you to think of that. That's beyond my expectation."

Duanmu Yu glanced at Youlian in surprise.

You Lian didn't say anything. She turned her head and looked at the darkness of the Ultimate Cross Barrier that sealed the ruins of Luluye, muttering, "With this level of sealing power, and the power of my pyramid barrier absorbed, the crisis of the earth is resolved..."

At this time, the performance of the Ultimate Cross Barrier was nearing completion, and the energy of the four Ultra Brothers was almost exhausted. The energy indicators on their chests and foreheads kept flashing.

"Roar!"

Suddenly, a melodious roar came from the cave where the evil energy was gushing out, like the roar of a wild beast.

Hearing the beast's roar, You Lian's face suddenly turned pale, and she stammered, "It...was awakened by the seal?"

"That's the strongest alien beast... Izumiru?"

Duanmu Yu also discovered something strange in the cave. He looked down with his super strong vision, and suddenly a giant beast that seemed to have integrated the characteristics of all alien beasts appeared in Duanmu Yu's sight.

It was the strongest alien beast Yizumairu that Duanmu Yu was familiar with!

Izumaru is not only the strongest alien beast, but also a very terrifying combined beast. This guy can be said to be a collection of all alien beasts, including the moves, energy, and power of all alien beasts that have appeared. Izumaru is too terrifying and once forced Nexus into a dead end.

Although he was killed by Nexus' strongest attack in the end, he was still an opponent that should not be underestimated. In his prime, he should have had strength close to that of an S-class powerhouse!

"This monster was born not long ago, but it is getting stronger every day. Hurry, stop it and don't let it break the seal, otherwise all our efforts will be in vain."

The witch Youlian looked nervous and looked at Duanmu Yu hopefully.

Now the only one who can stop Izumaru is the dark giant in front of him. For the future of the earth, Youlian couldn't help but beg.

"Do you even need to tell me that..."

Duanmu Yu rolled his eyes and quickly flew up. At the same time, the phantoms of Ultraman Tiga and the first Ultraman appeared beside Duanmu Yu. The next moment, they turned into Beta Spark Armor and put on Duanmu Yu's body!

Yizumairu is indeed very powerful and is known as the strongest alien beast. Now is the most critical moment of sealing the ultimate cross barrier. If it messes up, Duanmu Yu's efforts during this period will be wasted.

Therefore, even if it cannot kill Izumairu, it must be driven back into the cave. When the ultimate cross barrier is completed, no matter how strong it is, it will not be able to turn around!
