"boom…"

The heavy door-pushing sound rang slowly, and echoed around the extremely quiet under the push of two hands that were completely disproportionate to the door. The cold wind that was blowing all the time had stopped at some point, making the atmosphere on the scene look particularly solemn...

When the door was completely opened, speechless, Asuna and the others looked at each other, then took steps and walked gently in. After the two of them entered the room where the guard boss was guarding the door, the door behind them roared and closed tightly.

The two of them had no surprise expressions, and they didn't even have the urge to look back. They had encountered this scene many times. Since the 75th floor, there are two settings for each floor's guard BOSS room, one is the crystal invalid area and the other is the trap trigger.

In other words, if they step into the room of the Guardian BOSS, they will have no way to leave here again unless the Guardian BOSS dies!

Asuna had already known this setting, so there was no need to turn back and confirm. At this time, they had stopped and were attracted by the strange scene that had entered their eyes!

In front, a thick black cloud fog enveloped the area in the center of the room guarding the gate. It was squirming like a bug in the air. Several black mist-like objects floated around the clouds and kept churning. It looked very similar to the shadows outside, except that the cloak on its body was black. The head was a black fog, and the situation inside was completely invisible.

However, on the head of the black fog, there was a pair of red light spots that released a faint light, flashing like eyes, surging like evil spirits. Finally, a terrifying shrill scream came from the black fog. It seemed that something was trapped inside the black fog...

With such a strange scene, Wu Yan couldn't help but have the urge to take a step back, not to mention Asuna, who was already afraid of these, a serious face had collapsed.

"Then...what is that..." Asuna moved uncontrollably behind Wu Yan, holding the thin sword in her hand tightly and almost trembled.

"Where is the boss who guards the gate?..."

"Who knows..."

Wuyan looked at the black fog that was hovering in the air as if it was covering the sky. The scene where the light was originally very dim seemed to become even darker under the rolling of the black fog, and the strange black fog in the middle could not even penetrate the light, making Wuyan, who was trying to see the situation clearly, instantly defeated.

Countless sharp screams echoed in the black fog, and dense black shadows shuttled back and forth in the black fog, like evil ghosts hiding in the night. The red eyes were terrifyingly gloomy in the dim environment. This made Yan couldn't help but curse.

"This Kayaba Akihiko is really a bad thing..."

Asuna looked at the black fog shadows hovering in the air with a timid expression. The dense scenes of flying around made her feel numb. If she hadn't known that this was the room of the Guardian BOSS, they would have faced the Guardian BOSS. It is very likely that Asuna would not dare to stay here.

At this moment, Asuna had no choice but to calm down. She cheered up and hesitated for a while, and asked, "What should I do? Do I need to go over?"

Wu Yan narrowed his eyes, pointed the "Heavenly Seeker" in the direction of the black fog, and took Asuna's hand.

"You follow me, let's walk over slowly..."

Asuna nodded, letting her hand silently, and walked towards the direction of the black fog with a lighter pace...

Just as the two of them arrived at the range of about five meters in front of the black fog, the black fog that was constantly squirming suddenly stopped, and then it started to swell violently. A black shadow that could not be seen clearly flashed through the black fog. At the same time, a bright red blood light emerged from the inside, and a strange dark red color began to fluctuate!

"careful!"

The sudden change shocked me speechlessly. As soon as the reminder fell, a shrill scream rang out. After a moment, the black fog paused violently and was silent for a moment. Then, countless shadows of black fog passing around the black fog shot out from it, pouring down like a rainstorm!

"Word!"

"Back!"

The shadow of the black fog was overwhelmed by the shadows. Silently, Asuna and the others shouted in shock at the same time, and then jumped backwards!

The black fog shadow surged, and he pursued him unyieldingly. In an instant, he came to the two people who were retreating violently, and covered Wu Yan and Asuna's figures!

Wuyan's eyebrows condensed, and with his palms held, a green light flashed from the sword body of the "Sky-Watching Man" and was swung out by him. With the silent movement, a strong wind rushed towards the sky under the guidance of the "Sky-Watching Man" and blew on the black fog shadow!

The 'woo' sound kept ringing, and the black fog shadow was blowing by the strong wind and his body suddenly appeared on the spot. The black fog shadow also retreated a little, but the number of the latter was too terrifying, so there were still many black fog shadows shot down desperately and enveloped the two!

"There's nothing!" Wu Yan stopped suddenly and stood firm. He pulled out the 'interpreter' on his back.

"Asuna! Attack!"

"I see!"

Asuna flashed to Wuyan's side at the first time and saw the black fog shadows pounced on like a pack of wolves. The effect light of the sword skills flashed on the swords of the two people, and when the black fog shadows came, they slashed over hard!

"Bang!"

The sharp sword edge was amazingly powerful with the blessing of sword skills. The black fog shadow was torn apart after just touching it, which made Wuyan and Asuna happy, but soon sank again...

The torn black fog shadows turned into a grey gas in a blink of an eye and quickly fluctuated. When the two of them thought it would attack, they turned around and got into the wriggling black fog!

Something weird!

Silently, Asuna and the others had such an idea at the same time, but before they could observe carefully, other black fog shadows rushed over in the screams!

Wuyan swung his swords quickly, and every time the sharp sword light swept through a black fog shadow, it would penetrate a black fog shadow, but such a small black fog shadow was simply negligible compared with the number of wolves behind him. After killing dozens of black fog shadows, Wuyan finally couldn't help but breathe.

On the other hand, Asuna's situation was similar. Dozens of black fog shadows were pierced under her sword, but there was still a black fog shadow pounced on her behind. Over time, as the two of them slaughtered in such a large scale, the dark clouds with a hint of dark red also churned violently!

The black clouds surging layer by layer, and a trace of blood-red color penetrated out faintly, revealing a bit of weirdness and gloom. Whenever a shadow of black fog is killed, their bodies will turn into a grey gas, replenishing into the black fog, and the blood-red color becomes more and more intense.

As time goes by, a sense of oppression slowly came out in the black fog. During the tumbling period, a shrill sound of sounds frequently rang out...

The "Heavenly Looking at the Sky" and the "Explanator" flew, and the shadows of the black fog that would attack were killed under the sword one by one, but Wu Yan was not happy at all. His brows frowned slightly, and a feeling of something wrong flashed in his heart. The speed of swinging the two swords in his hand increased, and illusory sword shadows emerged one by one, instantly shattering a large wave of black fog shadows in front of him!

Taking advantage of this opportunity, Wuyan suddenly looked up and looked at the huge black fog above his head. When he saw that, Wuyan's pupils shrank.

Inadvertently, Wuyan saw that in the black fog, a huge figure that was as bright as a flame, slowly condensed with the supplement of gray gas...

“Can it be…”

Suddenly, the black fog contracted like a frightened, and the shrill screams that kept echoing also showed a brief silence. In the dark clouds, blood rays surged, and a creepy chewing sound gradually appeared inside...

Seeing this scene, a light flashed in Wuyan's eyes, and he raised his swords in his hand, stepped on his foot, rushed towards the black fog!

"Word!"
