On Blue Star, twenty-nine percent is land, and the remaining seventy-one percent is all ocean and rivers.

The twenty-nine percent of land nurtures trillions of living creatures, so how many creatures are nurtured in the ocean, which is three times larger than the land area?

Probably enough to reach hundreds of quadrillions!

Not hundreds of trillions, but hundreds of quadrillions!

The First Calamity era gave birth to many mutated beasts on land, but under the official emergency response, a large number of radioactive plants were destroyed, and the hunting of wild animals began, which controlled the large-scale expansion of mutated beasts.

Up to now, there are less than twenty perfectly mutated Beast Kings in the world.

But after the arrival of this Second Calamity era, this number is likely to increase dramatically!

The reason is simple: humans have not yet fully controlled the sea!

Humans cannot completely eliminate the radiated seawater, nor can they slaughter all the creatures in the sea. Even if all the nuclear bombs in the world are put in, they cannot do it!

It is conceivable that in the future, the mutated creatures born in the ocean will grow hundreds of times faster.

They will open up their intelligence, and they will no longer be satisfied with the sea, nor will they be satisfied with being ruled by humans.

They will climb onto the land and start attacking humans!

That will be an extremely tragic bloodbath.

Thinking of this scene, Li Tianran frowned tightly.

Which is better, this result or directly letting the seawater on Blue Star disappear?

No one can predict what will happen in the future.

It is worth mentioning that this radiation seems to be spreading from the inside of Blue Star, polluting all the underground water sources and the ocean, while some water towers and reservoirs that use special containers to store water and are separated from the earth are not polluted.

This can be regarded as a glimmer of hope in the dark world.

Otherwise, if all the water on Blue Star is polluted, the war will start immediately.

The powerful leaders who have lost hope for the future will stop at nothing to drag all the funeral-goers to hell!

"This water is already dead..." Li Tianran was silent for a moment, "It is certainly not suitable for drinking and raising fish. I don't know if it can be used to irrigate crops... It won't lead to mutated plants, will it?"

Li Tianran threw a radiation-resistant seed into the water and observed its data changes.

"Radiation-resistant Seed

Growth Rate: 1%

Growth Status: Good"

It can be used for irrigation!

Li Tianran's tense mood eased.

What he cares most about is planting. As long as the water quality can meet the irrigation requirements, the impact of ocean water quality changes on his life will not be too great!

Immediately afterwards, he also put the Guyao-grade (ancient medicine grade) seeds into the water.

There is not much difference between Guyao-grade and radiation-resistant seeds. Although the growth rate is a little slower, it is still good.

But the lv4 seeds were different.

The seeds sank into the water and began to shrink and wither at a speed visible to the naked eye, and eventually died.

"Sure enough... the growth environment of lv4 seeds is very harsh, and there are requirements for soil and water quality." Li Tianran recorded this situation.

Judging from the current situation, it is still impossible to grow lv4 crops on a large scale.

"Fully automatic industrial water purification machine."

Li Tianran turned his attention to the mall and found a heavy machine in a newly unlocked interface, which fully met Li Tianran's needs at this time.

"After connecting to the water source, it can purify all the impurities in the water, so that the water source can reach the level of irrigating lv4 crops and breeding lv2 and 3 fish. It can purify 1 ton of water per minute!"

"Price: 4,800,000 points!"

Four million eight hundred thousand points!

Li Tianran silently glanced at his balance of less than 100,000 points, and shed tears of poverty...

When will I be able to spend money at will in the mall?

"I almost forgot, I haven't opened my upgrade gift package yet!" Li Tianran slapped his forehead, he remembered the reward after the shelter was upgraded.

In the system backpack, a delicate package was quietly parked there.

"Do you want to open the lv2 shelter upgrade gift package?"

"Yes!"

With a flash of light, pleasant prompts kept ringing in Li Tianran's ears.

"Congratulations to the player for obtaining a Tank-class Battle Maniac!"

"Congratulations to the player for obtaining seeds (lv3 Guyao-grade): corn x 60 jin, soybeans x 60 jin, wheat x 60 jin!"

"Congratulations to the player for obtaining fish fry (lv3 Guyao-grade): grass carp x 600, bass..."

"Congratulations to the player..."

A series of upgrade rewards, most of which were similar to the first gift package reward, the most attractive to Li Tianran was the Tank-class Battle Maniac.

That was a tall metal warrior, about five meters tall, exuding a valiant and mighty aura all over his body.

Behind it was a thick cannon barrel, a machine gun hanging on its left arm, and an extremely wide chainsaw-shaped steel knife on its right arm. It looked exceptionally majestic, like Megatron in Transformers!

Compared to the adult-level Battle Maniac, it was more like a mad shark in a group of goldfish.

"Tank-class Battle Maniac

Attack methods: shelling, cutting, burning, machine gun coverage!

Ammunition capacity: unlimited firepower

Power source: 100/100

Speed: 18

Lethality: 95

Defense: 95

Attack range: shelling 1200 meters, cutting 5 meters, burning 50 meters, machine gun coverage 800 meters!

Description: This is a slaughtering machine like a steel fortress. Its powerful firepower will clear all obstacles and enemies in front of you. It is the guarantee of freedom and the nightmare of tyrants!"

Li Tianran's eyebrows twitched wildly after seeing these data.

The sniping lethality of the adult-level Battle Maniac is less than 20, and it can already penetrate a steel plate nearly 3 centimeters thick. The lethality of the Tank-class is five times that of the adult-level. This is enough to show that its lethality is really comparable to the world's top combat tanks!

Moreover, compared to heavy tanks, humanoid Battle Maniacs are undoubtedly more mobile!

Tap tap tap!

An extremely light footstep sounded, and a huge shadow enveloped it.

Li Tianran looked up and saw a black giant dog whose size was no less than that of a Tank-class Battle Maniac walking up to him.

"Xiao Hei (Little Black)

Identity: God-descended Evolution Wolfhound

God-descended characteristics: intelligence, water bear, titan!

Strength: 1180 (converted lethality 118)

Intelligence: 85

Speed: 210

Spirit: 80

Evaluation: Every God-descended evolver will awaken three characteristics, but its luck seems to be heaven-defying. Its three characteristics can be called top-level God-descended. "Intelligence" gives it intelligence no less than that of top humans, "water bear" gives it nearly unlimited life, and "titan" gives it terrifying power! Intelligence, vitality, and power are integrated into one. This is an almost perfect Beast King!

At this moment, it is most appropriate to describe it in one sentence: The universe will not explode, and it will not hang!"

Li Tianran stood up. Seeing this, Xiao Hei whimpered and lay down next to Li Tianran's feet. Red light flickered on its body again. That was its fatal weakness.

Defect mastered...

Even such a powerful God-descended evolution has flaws.

Li Tianran gently stroked Xiao Hei's big head, looked at the dim sky in the distance, and said softly:

"The new disaster has finally arrived."

"I am ready to face any danger and difficulty. This time, my goal is not just to survive..."

"I want to... change the world."
