genetic catastrophe

Zhao Dong smiled faintly, gently held Yang Ni's waist from behind, and asked: "Then you should tell me what the instruments you need are used for..."

Yang Ni's body trembled slightly, but she didn't struggle, but her cheeks turned red, and she whispered: "First of all, we need a container that can collect cakes to store biological energy. Secondly, we need to subdivide and transform this energy, because the biological energy of genetic beasts

The energy is too complex. If it is directly condensed, the cells and genes of the evolver will be affected. In the end, there will be a medium that can carry this energy..."

"Unfortunately, there are no materials known to mankind that can perfectly carry this energy."

Seeing the slight sadness on Yang Ni's face, Zhao Dong let go of her, and then spread his hands in front of her. Blue light shone in his palms, and several azure crystal stones appeared in his palms.

"This thing should fully meet your requirements. As for the instrument you mentioned..."

Zhao Dong quickly rummaged through the system and finally found an item with similar functions. But in fact, it was also a weapon, but its purpose was to swallow a large amount of biological energy in advance and then compress it and explode it.

In essence, it is similar to his sniper rifle, but the sniper rifle is too dangerous and cannot be placed next to Yang Ni, otherwise it will attract the covetousness of interested people!

"This thing should be able to fully meet your requirements. The principle is the same, but it's actually a weapon, not an instrument."

Yang Ni looked at the weird blue object in front of her with bright eyes, and she couldn't make a sound for a long time.

Zhao Dong looked at Yang Ni's side face calmly. After a moment, Yang Ni suddenly turned around, threw herself into his arms again and again, and said in an excited voice: "Thank you, thank you really, if it weren't for you,

I really don’t know what to do…”

Zhao Dong raised the corner of his mouth and asked with a smile: "According to the plot of the Korean drama, are you going to thank me in some way next?"

"What a beautiful thought..."

Yang Ni glared at Zhao Dong with a hint of anger, but the next moment she tiptoed and kissed Zhao Dong gently on the face.

Zhao Dong's heart trembled, and before Yang Ni could escape, he pulled her into his arms, raised his hand to hold her chin, and slowly moved his mouth towards her.

Yang Ni's eyes widened and she wanted to escape, but her body didn't obey her orders at all.

However, when the distance between their lips was only a few centimeters, the whole room suddenly shook violently.

All the electronic instruments flashed with electric arcs, and the ground cracked and expanded rapidly, revealing bottomless cracks. However, new soil soon poured out from the bottom of the cracks, filling and healing the cracks!

Zhao Dong held Yang Ni in his arms, his expression became serious, the cement and steel bars above his head broke and fell, but he blocked them all with one hand!

The shaking lasted for about ten minutes, and the entire research room was beyond recognition. Judging from the marks on the broken walls, the ground under their feet seemed to have grown several times larger!

"What's happening here?"

Yang Ni stared blankly at the ruins around her, her eyes filled with confusion.

But before Zhao Dong could speak, a cold electronic sound exploded in everyone's mind!

At this moment, all humans on earth heard the same voice at the same time!

[Hey, the timestamp is messed up, triggering a world task!

Mission name: Guard the fire.

Mission content: Survive and fight back under the invasion of powerful enemies from all sides, ensuring that the last fire of mankind is immortal and the inheritance of mankind is immortal.

Mission duration: 740 solar days.

Completion rewards: Ranked based on contribution, the top three will get part of the truth about the universe, time and space, 7-10 will get a world will of their own choosing, and will be qualified to become guardians, and the rest will be qualified to live.

Failure penalty: erasure of all humans and restart the era.]

Yang Ni looked at Zhao Dong with a pale face, and said with a slightly trembling voice: "Zhao Dong, did you hear..."

Zhao Dong took a deep breath, nodded, and said in a deep voice: "I heard it. I'm afraid everyone heard it. Now I'm in trouble!"

"It seems that this disaster is indeed controlled by a higher-level force. No, I have to speed up the experiment!"

Without waiting for Zhao Dong to say anything else, Yang Ni picked up the weapons and crystals beside her and ran away.

Zhao Dong hesitated for a moment and frowned more and more. He probably guessed the whole story. It was probably because he abused the weapons and equipment in the system and made the level of human science and technology far beyond the original timeline. That's why it happened.

Trigger this mission!

And he can be sure that the power behind it is definitely related to his system!

After thinking about this, Zhao Dong felt a little relieved. Since the existence of the system was not intended to harm him, it means that this so-called world mission is actually beneficial to mankind in a certain sense and may help mankind.

Break through the limitations of the earth and officially enter the level of the universe!

Zhao Dong came outside the ruins of the research institute and glanced around. The entire gathering point had expanded several times. Although the temporary houses and equipment had been completely destroyed, fortunately no one was injured.

"Dongzi, what the hell was that just now? Did you hear it?"

Wang Lei and the others came running from a distance. Everyone was looking disgraced. Dong Zhuo was even shirtless and hadn't even had time to fasten his belt.

Zhao Dong nodded to several people and said in a deep voice: "It seems that we don't have time to waste here. According to the description of the voice, I am afraid that there will be a powerful enemy from unknown origins next, and it is very likely to threaten the entire

The survival of mankind!"

When several people heard this, their expressions instantly became solemn. Zhao Dong was their spiritual support. Now that even Zhao Dong can't guarantee anything, the fate of these people will be unimaginable.

Several people looked at each other, their eyes filled with determination.

Zhao Dong said in a deep voice: "Rebuild the gathering point immediately and strengthen the guards. In addition..."

Zhao Dong paused and narrowed his eyes, "Before those unknown enemies arrive, you should still have some time to upgrade your level, and it seems that the earth itself seems to have expanded. It is estimated that some changes have occurred outside the gathering point.

You can take people to see the situation, and you may find unexpected gains."

The eyes of several people suddenly lit up, they looked at each other, and immediately went to do what Zhao Dong said.

Zhao Dong himself found Erha and Bai Bing and asked them to stay at the gathering point to guard Yang Ni. Duoduo said goodbye to Zhao Dong with some reluctance and let Yang Ni take care of them.

After leaving the gathering point alone, Zhao Dong directly started his journey of killing monsters. Now those A-level or even quasi-S-level gene beasts can no longer enter his eyes. Only those true S-level gene beasts can let him.

He gained something!

However, S-class genetic beasts already have a certain level of intelligence and cannot be discovered easily. It took a whole week to find an S-class genetic beast, and it was the kind of guy who was at the bottom of the S-class!

"Damn, the land area has increased several times, and finding the genetic beasts has become several times more troublesome!"

"It seems I can only try to find it in the water..."

Zhao Dong hesitated for a long time before finally deciding to go to the coastal city and search for powerful genetic beasts in the sea!

After all, if the land area is too large, it will be difficult to find them if they are hidden, but it is different for those guys in the sea. They will definitely take the bait with just a little temptation!

…

"Hmm... It seems that this set of equipment does allow me to breathe freely in the water, and even the water pressure and resistance are offset to a great extent. Apart from the lack of a sense of fulfillment, it is no different than on land.

"

Zhao Dong walked slowly down the bottom of the shallow water area, and all he saw was darkness. Except for the occasional huge fish that passed by him, there was almost nothing.

The equipment he was wearing was specially redeemed from the system in order to be able to hunt genetic beasts in the water. It cost a total of 50,000 points, but the effect was beyond his expectation.

After advancing for some distance, a dark space appeared in front of it. It seemed to be an undersea cliff. It was so dark below that you couldn't see the bottom. Just taking a look at it was terrifying!

"strangeness……"

"There seems to be something wrong with this terrain..."

Zhao Dong frowned and looked at the deep cliff in front of him. His intuition told him that there must be some powerful guy waiting for him down here!

Arriving at the edge of the cliff, Zhao Dong could clearly feel the water velocity half a meter in front of him suddenly increase, and even the temperature dropped several degrees!

"snort……"

Zhao Dong snorted coldly. Since he couldn't use the particle sword underwater, he took out his sniper rifle, charged it briefly and fired at the bottom of the cliff!

A ray of blue light cuts through the darkness, flashing towards the darkness at the bottom of the cliff with a series of boiling bubbles. Wherever the light passes, you can see huge and twisted outlines!

In just a few seconds, the shot seemed to have hit something, and it suddenly exploded!

Along with a dull roar, the entire edge of the cliff began to shake violently, and the sea water rolled, rolling up waterspouts, leading straight into the darkness below!

Zhao Dong narrowed his eyes and fired a few more shots. The next moment, the waterspouts connected to the bottom of the cliff suddenly turned dark purple, as if something's blood was mixed in!

Bang!

A muffled sound exploded, and the entire seafloor ground shook. An extremely thick octopus tentacle rolled out from the darkness and shot directly towards Zhao Dong!

Wherever the tentacles passed, even the sea water was briefly split into two, the water surged, and everything in the affected area was crushed and swept away. The destructive power was amazing!

Zhao Dong's eyes showed a cold light, and he kicked off his right leg suddenly, using the impact force to launch upwards, and the sniper rifle in his hand fired at the octopus tentacles one after another!

Bang bang bang!

A series of faint blue beams penetrated the water flow and hit the same part of the octopus's tentacles, breaking them off!

But Zhao Dong knew in his heart that this was just a warm-up before the battle. Judging from the size of this octopus's tentacles alone, the size of the guy below was definitely not too small!
