"Activate the stealth device!" With Ounok's command, all the equipment on his body was activated. One of the most critical pieces of equipment is the Stealth Mobile Device. This thing allows Onno to completely disappear into invisibility to a certain extent. However, this device also has a weakness, that is, if there are people nearby, the concealment device will fail, and even the person using the device will not be able to see everything around them clearly for a period of time.

"Buzz!" A soft voice sounded, and the figure of Onno gradually disappeared into the biological laboratory, and the mastermind and some of the soldiers who rushed back after hearing that they had been attacked could not find any trace of Onno even through infrared detection. After testing the performance of the equipment, Ono said a word to the mastermind and set off with Ya.

With the stealth mobile device activated, Onno's original walking speed slowed down a lot, because now his perspective is very weird and distorted, even with Ya's real-time correction, Onno can only see the normal ground less than a meter in front of him, and the farther away presents a strange and distorted feeling.

Onno walked cautiously forward. The soldiers on the front line are still fighting bloodily, and some of the weapons in their hands have already been alarmed. The energy shield in front of him has also been rereplenished at least ten times. But this group of guys just fought to the death, and their numbers have always remained at a high number.

Over time, the soldiers also felt a little tired, but they didn't even have a peaceful moment to rest without resisting the attacks of these monsters. Not to mention that they had just received the news that the mastermind and the highest authority had been subjected to a "decapitation operation" by the enemy! Fortunately, the combat power of the supreme authority itself was spared.

At this point, Onno had sneaked in the direction of another passage leading to the bridge, discovering a large number of monsters and geometric shapes along the way. However, these guys seemed to be in an inactive state so far from the battlefield, and all of them stood motionless, as if waiting for something.

Onno didn't make a move when he saw them, after all, it was easy to kill them, but it was not good to arouse the alertness of the monsters on the front line and the monsters in the rear! After rounding the monsters and geometry, Onno came to another door in the bridge. At this point, his speed was still very slow.

According to the information transmitted by the mastermind, monsters and geometries are still tirelessly attacking the front line without any attrition, although the energy shield intercepts the rays of those geometric figures, but each recharge will cause several fighters to be wiped out of combat effectiveness! As for the creatures, the ranged monsters among them are also constantly spitting out things such as acid, plasma fireballs, or electric arcs, constantly weakening the energy shields and combat effectiveness of the soldiers.

When Ono heard this, he quickened himself a little, and although he was a little dizzy, he came to the vicinity of another gate on the bridge. After entering the code for the bridge, the door to the bridge opened. Onno slipped in quietly. And before the monster inside the bridge was discovered, he hid in a relatively dark corner and began to quietly observe the situation of the entire bridge.

The door to the bridge that Onno entered was actually one of the very few doors that were usually used, and the monsters found it, but they didn't pay much attention to it, leaving only a small number of inactive creatures standing or floating in that place. When Ono entered through this door, he found that a large number of monsters had hit near the captain's seat on the bridge. And that's where the portal exits.

Unno, who was secretly observing, first observed the portal passage, and found that it was already shrouded in a black thing, and there were constantly creatures, monsters, or geometric shapes emerging from that place and approaching the direction of the front line. As for the three boss-like guys, they stood near the entrance of the portal, commanding all the monsters, and the female scientist monster also secreted a large amount of pale yellow liquid from her body for these monsters to mutate and strengthen again.

"Operation Stealth removed!" With a whispered order, his figure slowly emerged from the darkness, and the metal blade on his arm silently stretched out. The armor pieces and various firepower weapons behind the back have also been appropriately adjusted, trying to decapitate these three guys "quickly, accurately, and steadily"!

"Ya, probe where their possible weaknesses are?!" In this environment, Onno became cautious when he spoke, after all, it would be really difficult to escape if he was discovered! After hearing Onno's words, Ya quietly activated the detection device on the equipment and conducted a test on the three leader-like guys. Just after scanning the bodies of these three guys, one of the monsters noticed something.

The monster that has been noticed looks very weird, and its whole body is like the standard embodiment of an impossible cube floating in the air and constantly circulating! The infinite shape of the transfiguration makes this guy take on something called a Klein Bottle, which is extremely mysterious. It is precisely because of this that this guy's perception ability is extremely powerful! It sensed something to them in the first place?!

"Huh?!" The Klein Bottle turned its body to swallow the air around him, looking into the dark corner where Unnor was hiding, and his powerful sense scanned the place over and over again, trying to find out what was there. It's just that at this time, Onno has already shifted his position, and when he saw the Klein bottle constantly performing destructive scanning of the location he just was, he couldn't help but sigh secretly that he was fortunate to have shifted his position.

"Gollum?" The creature monster also sensed the anomaly of the Klein bottle and asked, but the language it used was strange and distorted, as if someone was playing heavy metal rock music backwards, unusually noisy and unpleasant. After responding to the creature monster in the same language, the Klein Bottle unleashed a powerful destructive scan of the area, leaving nothing unfounded.

And on the side of Ono , Ya through that inspection of the bodies of the three guys, can only determine that the weakness of the female scientist monster is the two heads, as for the other two, these two monsters are not understood by common sense at all, that biological monster is okay to say, that Klein bottle really doesn't know where the weakness is!

"Then what to do, there can't be one left! And I don't know what weird abilities this guy has! Unnor and Ya deliberated as they observed the movements of the three monsters. Gradually, the two of them discovered that the creatures of the three monsters, the monster and the Klein Bottle, turned back into the darkness of the portal passage every once in a while, and they didn't know what to do. And the female scientist monster will squirt some pale blue liquid from the mouth of the toothy baby into the two monsters after they come out.

Onno looked at the strange behavior of this monster disgustingly, and didn't know what to say for a while, after all, the way these monsters acted couldn't think in normal thinking at all. Just as Ono was observing, the mastermind sent a message again, saying that there were some monsters fusing with each other on the front line, and these fused monsters had even more terrifying new abilities! The soldiers were caught off guard and broke through the line once! Although the defense line has been reorganized again, it has faded a lot from the previous one!

After hearing this information, Angnuo immediately reacted, the three boss-like monsters in front of him were merging all the monsters into everything, stronger bodies and more terrifying abilities, and the female scientist monster was the glue that fused these monsters into everything!

Thinking of this, Onno understood that these three guys could never stay any longer, even if he didn't know the weaknesses of these three guys, he would go up and kill at least one of them! The metal blade in his hand was quickly heated and reddened, and the plasma weapon behind it also lit up! Then Onno emerged from the dark corner and rushed forward in two steps before the Klein bottle could react!

"Buzz!" The blue arc of the plasma weapon hit the creature monster and the Klein bottle directly, and the metal blade in Ono's hand sliced off the head of the female scientist monster like cutting butter, and by the way, the second head was also chopped off! The creature monster and the Klein Bottle are suddenly attacked, and the power of the plasma weapon leaves the two of them at a loss.

When Ono saw that these two guys were immobilized by himself, the metal blades on his two arms stretched out again and plunged into the exposed brains of the biological monsters and the translucent hard shell on the outside of the Klein bottle! All I heard was a "poof!" "The creature's head was pierced, and the Klein bottle was struck by the metal blade through countless gaps.

After doing this, Onno immediately jumped back to prevent these guys from still having a defensive backhand, and when he just jumped out of the range he was standing on, both the creature monster and the Klein Bottle reacted, one of the two monsters released a large amount of acid on the ground and the other fired two rays towards Onno!

The energy shield on Ounok's body instantly defended against these two rays! It's just these two rays that reduce the capacity of Onno's shield to less than 20%. At the same time as Ono was attacked by these two guys, the metal blade on his arm was also launched at the right time!

The dark red, hot metal blade with Onno's terrifying vortex ability pierced the bodies of these two guys through a short distance! After the creature monster suffered a second attack, its brain was pierced and shattered, and all six legs fell to death in place! The translucent body of the Klein Bottle was about to shatter when it was pierced!

"Dead silence won't forgive you!" After Klein Bottle said this, his entire body turned into countless translucent fragments, falling to the ground and gradually dissipating into the air. As for the darkness of the portal passage, it disappeared after the two monsters were killed.

"Sir! The number of these monsters is decreasing! "The soldiers fighting on the front line suddenly found that the number of monsters was no longer how many were destroyed, but how many appeared, but were being completely eliminated one by one by the explosive guns in the hands of the soldiers. After learning about the situation on the front line through the mastermind, Onno used his ability to carry out a murderous slaughter of the monsters still on the bridge, and after destroying two-thirds of the monsters on the bridge, he came to the portal passage.

The passage was full of dead monsters or turned into geometric shapes like stones, and the light waves like water on the portal not far away were constantly decaying, and under the reddish-brown light on the other side of the portal, several figures stared at Onno with a hateful gaze for a long time, until the light of the portal disappeared......
