With Grizzly's command, all the survivors turned their guns and poured a rain of bullets towards the horde of zombies surging from the parliament building. While their firepower was weak against the giant tyrant, it was more than enough to deal with these level one enhanced zombies.

In an instant, the onrushing zombies fell like wheat being harvested. Some were directly shot in the head, while many more were hit in the body, resulting in mutilation, yet they still limped forward, even crawling on the ground.

The people Li Chenzhou had chosen were mostly soldiers from the warships, but they weren't infantry in the traditional sense; they were sailors. So their marksmanship was definitely lacking.

Li Chenzhou had, of course, noticed the surging tide of zombies, but he was currently engaged in combat with the giant tyrant and couldn't spare any attention. Moreover, it seemed that he was the only one who could temporarily hold the giant tyrant back.

Although this giant tyrant was only level three, it definitely couldn't be equated with ordinary level three zombies. In his previous life, Li Chenzhou didn't know how many level three zombies he had killed, and he had even soloed zombies of this level when he was also level three.

Therefore, he was quite clear that the strength of a level three zombie absolutely couldn't reach the level of the giant tyrant before him. He was much stronger now than he was in his previous life at level three, and if the giant tyrant was just a regular level three zombie, he would have already killed it!

"Damn it, whatever, I'll try the heart first!"

Seeing the tide of zombies rushing out of the parliament building about to reach the area where he was fighting the giant tyrant, a ruthless look flashed across Li Chenzhou's face, and he decided to make his move ahead of schedule.

When Li Chenzhou was entangled with the giant tyrant earlier, he had not used his ability, because he wanted to first confirm where the vital part of this giant tyrant was, and then strike.

Li Chenzhou also possessed an attack ability that ignored defense, but it could only be used once, and it required a melee weapon. The only thing better than Grizzly's skill was that Li Chenzhou's Fatal Strike added a guaranteed hit state when activated; the target couldn't dodge and could only withstand it.

So, as long as Li Chenzhou could find the location of this giant tyrant's crystal core, a Fatal Strike should be able to take it down! This was the reason why Li Chenzhou had been constantly fighting the giant tyrant.

But now, the tide of zombies had appeared again. Just a giant tyrant already required Li Chenzhou to do his best to restrain it, and now there was also a tide of zombies composed of enhanced zombies...

"Ha!"

Now that he had made his decision, Li Chenzhou no longer hesitated. With a furious shout, his figure instantly became erratic, like a breeze as he swept in front of the giant tyrant, the long staff in his hand thrusting out at its left chest like a spear...

"Crack! Pfft!"

Because he used Fatal Strike, the long staff in Li Chenzhou's hand instantly pierced through the giant tyrant's chest armor, stabbed into its chest, and then directly penetrated its body, emerging from its back...

"Roar!"

The giant tyrant immediately let out a wild roar, its left hand grabbing fiercely towards Li Chenzhou in front of it. And along with this roar, the speed of the attacking zombie tide became even faster, even frantic.

Li Chenzhou immediately let go, abandoning his long staff. After his body landed, he dodged behind the giant tyrant, forcefully leaping up, grabbing the long staff protruding from the giant tyrant's back, and kicking the giant tyrant in the back at the same time.

Using the force of this kick, Li Chenzhou's body suddenly surged forward, and the long staff was also pulled out of the giant tyrant's body with this force. Then, Li Chenzhou, who was in the air, swung the long staff, which was still unstained by blood, and smashed it fiercely at an enhanced zombie that was pouncing at him head-on.

"Pfft!"

The enhanced zombie's head instantly exploded, and Li Chenzhou put his foot on the zombie's body to stop his fall, his body rising again, and then landing in the horde of zombies.

Because Li Chenzhou was here, the survivors behind him avoided this area with their bullets. After Li Chenzhou fell into the zombie horde, he didn't rush to start killing, but desperately rushed forward a distance in the zombie horde. After smashing the zombie in front of him to death, he squatted down and picked up a crystal core from the ground!

This crystal core belonged to the giant tyrant. It was also the size of a ping pong ball, but it was crystal clear and emitted a faint blue light!

Mutated crystal cores are basically the same size because they are not graded by size, but by color!

All crystal cores are nearly transparent crystals, a bit like diamonds or crystals, but with a faint color!

The lowest level 1 crystal core doesn't actually have any color, but the crystal core of this level is more turbid and not particularly clear, as if there are many impurities inside, so it looks gray.

From the level two crystal core onwards, the crystal core itself begins to become transparent, without impurities, and the level two crystal core itself will appear a faint green.

The crystal core in Li Chenzhou's hand was level three, so the color presented was light blue.

And above level three, the colors are successively level five purple, level six orange, level seven gold, level eight pink, level nine red, and the legendary overlord-level crystal core, which only overlord-level zombies or mutated beasts can produce, is completely colorless, without impurities, and looks quite pure and transparent, truly like a crystal or diamond.

Of course, Li Chenzhou had never seen overlord-level zombies, nor had he even heard of them, so of course he had never seen an overlord-level crystal core. But he had at least seen a level three crystal core, so, as soon as he got it in his hand, he could be sure that he hadn't seen it wrong just now.

Before, that Fatal Strike, Li Chenzhou was completely gambling, because he didn't know where the vital point of this damn giant tyrant was, so he simply followed the thinking of a normal person and went for its heart.

And with just this one strike, when his long staff pierced through the giant tyrant's body and protruded from its back, Li Chenzhou saw a crystal being poked out by the long staff.

That's why Li Chenzhou was so anxious to come here to see if this was the giant tyrant's crystal core. Now it seemed that he had really succeeded.

"Pfft, pfft, pfft, pfft!"

After obtaining the crystal core, the pressure in Li Chenzhou's heart was greatly reduced. He knew that this giant tyrant couldn't be the guy controlling the zombie tide, but he must have spent a lot of effort to cultivate this main force, even his trump card.

The guy's previous silence was likely to be in the process of creating this giant tyrant, but now, it had been completely killed by himself. Li Chenzhou wanted to see what else this guy could use to resist him!

"Boss! Come quickly, we can't hold on anymore!"

Just as Li Chenzhou was knocking a few zombies to death, Grizzly's roar suddenly came. Li Chenzhou quickly looked in the direction of the sound, and was shocked to find that Grizzly was holding his head and desperately drilling into a building. Just as he entered the building, a spiked club swept across, smashing the wall behind him directly. Holding the spiked club was none other than the giant tyrant...
