[You killed the primary artificial intelligence LV2*3, life source +45]

[You killed the intermediate artificial intelligence LV3*2, life source +80]

[You killed ......]

The broadsword swung along the road and wreaked havoc, destroying an unknown number of robots and portals, and the entire walkway was stained red with alarm lights.

The noisy sirens sounded non-stop, and Liu Yuanyang kept searching, layer by layer, from the top floor to the bottom, and destroying layer by layer.

He only knew that the balance of the life source had already exceeded the 800 mark.

The road ahead was still full of dangers, and the cannonballs and even lasers that suddenly came over, he didn't blink his eyes, and shattered them one by one...... or dodge.

When he broke open the elevator door again and came to the F16 floor, he was startled by a large group of robots in front of him.

There were more or less several bots per layer before, but none of them were so exaggerated.

At a cursory glance, there are six intermediate AIs in LV3 and eighteen in LV2 in junior AI.

Even in the middle of this group of robots, there is a robot with a particularly powerful shape and a red flame pattern all over it.

Advanced Artificial Intelligence LV4

"Are all the remaining robots here...... So, that's where the most important thing comes in......"

Liu Yuanyang stood at the entrance of the damaged elevator.

Take a deep breath.

"Finally found it......"

[You killed the primary artificial intelligence LV2*4......]

[You killed the intermediate artificial intelligence LV3*2......]

Broadknives swung wildly through the robot pile, mechanical debris tossed, sparks and the smell of engine oil filling the spacious hallway.

"Excited—"

A round hole opened in the chest cavity of the flame pattern's advanced artificial intelligence, and after the highlighted energy in it briefly converged, it suddenly spit out a killing light and shot towards Liu Yuanyang.

Liu Yuanyang held the knife horizontally in front of him, blocking this killing light until it collapsed, and then he went straight forward, splitting this advanced artificial intelligence in half with a single sword.

[You killed the advanced artificial intelligence LV4*1, life source +80]

A moment later.

The hallway fell silent.

The ground was littered with mechanical remains.

Xu Tian dragged the big knife to the gate at the end of the corridor.

This should be the first time he's killed all the monsters in one place.

The current Life Source balance is ...... 1433！

He clicked on the plus sign for the upgrade.

Life source plummets to 1033.

The realm has reached the ninefold (Yuan Dan) of the solid foundation.

His sea of qi began to stir, and his vitality began to condense as it expanded wildly, and finally spun and condensed into a glittering pill, which contained more than five times as much vitality as before.

In other words, Liu Yuanyang's strength has also increased by more than five times, and his qi and blood have also returned to their peak.

At this point, the plus sign is gone.

"There are more than 1,000 life sources left, which is not enough to continue to upgrade?"

Liu Yuanyang secretly wondered.

Yes.

It should be about to break through the great realm......

Other than that, there should be no other possibility.

He looked at the particularly large mechanical door in front of him, raised the flame knife, and slashed down with all his strength.

To Liu Yuanyang's surprise, who had been like a bamboo from the beginning, the mechanical door in front of him did not move at all.

This iron knife that sharpens like clay has not been able to break through this door.

"Shhh...... What kind of material is this? ”

Liu Yuanyang was surprised, bit his fingers, and finally had to honestly walk to the screen next to the door and click the password lock.

The note that I accidentally saw earlier that was pressed by a dry corpse is definitely a clue that cannot be ignored, and its purpose should be to guide players to kill the boss, just like the old man who appeared in front of Lin Bao'er in Fallen Leaf Town.

Now it seems that the content of the note really matters.

In order to find the boss, the password is essential.

It's just that the man claimed that the password was his birthday......

And Liu Yuanyang, who was wandering in the base in the future, never found any clues about that Dr. Zhou He.

Not to mention something as secret as a birthday.

For ordinary people, they should be helpless at this time.

Fortunately, Liu Yuanyang is in the second class.

He clicked on the input method switch, switched from the default number input to Chinese character input, and then entered four large characters:

My birthday.

Click Confirm!

"Click......"

The sound of gears turning.

The door actually slowly moved to the left and opened!

The corners of Liu Yuanyang's mouth rose slightly.

Sure enough, it shouldn't have been so complicated in the first place.

The password is my birthday.

That's the four Chinese characters for "my birthday".

"......"

Dragging the heavy flame knife, Liu Yuanyang walked into the door step by step.

Suddenly it became clear that this central control room was very large, and there were all kinds of electronic devices inside, although it was empty, all the computer monitors were lit, and the green data beating on it showed that these devices were in operation.

Liu Yuanyang continued to walk forward.

At the end of the central control room, there is a large screen that is at least 75 inches or more.

What attracted Liu Yuanyang's attention was not the size of the screen, but because there were a pair of cartoon eyes and a mouth on the screen.

It's like a giant square cartoon face.

"Malu Xingren, why do you invade my territory if you don't violate the river water with my well water?"

This "giant face" was staring at Liu Yuanyang coldly, his mouth opening and closing, and a sweet female voice came out.

Liu Yuanyang ignored it at all, but looked straight to the left, where there was a mechanical pillar with a line of words on the pillar:

Top AI LV5

That's what it is.

Liu Yuanyang didn't say a word, picked up the big knife and slashed at the mechanical pillar, but at this moment, four thick mechanical arms ejected from the device next to him and blocked in front of the mechanical pillar.

At the same time, the four mechanical arms opened one cannon after another, spewing flames towards Liu Yuanyang.

Liu Yuanyang's eyes widened in shock, and when he was caught off guard, the whole person was drowned by fire snakes.

He immediately activated the vitality in the Yuan Dan and raised his body surface defense to the extreme, only to find that with his current physical fitness, this kind of flame could not hurt him in the slightest.

At that moment, he had no worries, raised the Yan Knife, and split the four mechanical arms one by one, which was overwhelming, and finally slashed at the mechanical pillar.

In an instant, the surrounding lights went dark.

All electronic devices ceased to function at this moment.
