After Professor Nan said this, Li Tianran suddenly realized that there were a total of ten LV4 crops planted in this culture dish, but only two had withered. Compared with the survival rate of LV4 crops planted by Li Tianran before, this was obviously more than twice as high!

"Before, you mentioned planting LV4 crops, but the survival rate was low..." Professor Nan continued, "So I modified its planting conditions."

"Are these crystals?" Li Tianran's eyes locked on a small crystal, and soon, detailed data appeared in his eyes.

"Evolved creature bone powder mixture."

Nine large characters appeared in front of Li Tianran.

"That's right!" Professor Nan said with a smile, "We have been eating the meat of evolved creatures, which has greatly improved our physical fitness, and has also eliminated some diseases and bacteria. This proves that the flesh and blood of evolvers has a great effect on improving physical fitness..."

"And I had an accidental whim that plants are also a kind of creature. Although they grow in different ways, they can all obtain nutrients from the remains of creatures and strengthen themselves."

"So I crushed some evolved creature bones, mixed them with some nutrient solution, and after several ratio adjustments, finally created this mixture."

Professor Nan took out a test tube containing half a test tube of white crystalline powder.

"Of course, the experimental process was difficult. Several times, the crops were wiped out because the proportion of the medicine was wrong."

"But the final result is good."

"Mixing this stuff in the soil as fertilizer can keep the survival rate of LV4 crops between 70% and 90%!"

Professor Nan smiled.

Li Tianran was silent for a long time after hearing this. Suddenly, he turned around and grasped Professor Nan's hand, and said very seriously: "Professor Nan, letting you come here was truly the most correct decision I have ever made in my life! You have helped me a lot!"

Professor Nan was a little flattered when he heard this, and a bright smile appeared on his face: "I am very satisfied that an old guy like me can help a little and get a little recognition!"

Although Li Tianran's words were a bit exaggerated, the fertilizer developed by Professor Nan for LV4 crops did solve a difficult problem that had been bothering Li Tianran for a long time.

"Professor Nan, I won't say much about gratitude... Time is tight and the task is heavy now. You immediately manufacture this mixture in large quantities, as much as you can! If the raw materials are lacking, tell me, and I will go out to sea to hunt beast kings for you!" Li Tianran said very simply: "With it, the speed at which we form the evolver army can be multiplied several times!"

Professor Nan nodded: "I will."

"My luck seems to have gotten better recently... Ever since the uranium was retrieved, everything has started to go smoothly." Li Tianran's eyes glowed: "The Third Doomsday is really my lucky day!"

...

Three days passed in a flash.

This was the fourth day after the Doomsday, and in the past three days, the world situation had changed again.

The beast kings seemed to have a very quick understanding of the human world's intelligence. They knew about the disappearance of minerals on the first day of the Third Doomsday. Then, they also seemed to know that humans were about to follow the same path as them, so even more frantic attacks began.

In just three days, seven more small countries were destroyed, and even the European Union, Russia, and the Yanhuang Federation had to be forced to abandon three or four coastal cities.

Of course, it was not only because of the beast kings' frantic attacks, but also because the lack of mineral resources made the supply of weapons no longer continuous.

In the past, when facing a wave of beast tides, human defenders usually wiped them out with a round of missile volleys.

But now it is different.

Without mineral resources, it means that weapons cannot continue to be manufactured, and every missile fired is one less!

If a country's heavy firepower is completely exhausted, but the evolver army has not yet been formed, then the country's defense forces will fall into a vacuum. The beast kings swarm up, and the country will be destroyed!

Under this concern, the upper echelons began to save firepower. The combat method of heavy firepower flattening in the past has also been changed to soldiers with light firepower as the main force and heavy firepower as the auxiliary force. Before the evolver army replaces the country's heavy firepower, everything must be based on conservation.

Under this combat method, the number of casualties among soldiers has greatly increased.

Under these circumstances, it is unrealistic to continue to defend the once vast territory. Many countries have begun to consolidate their defenses, abandon some peripheral and coastal cities, and shrink their forces in inland cities to form new battle lines.

In the war with the beast kings, humans have retreated for the first time and are vaguely at a disadvantage.

But the more this is the case, the more rampant the beast kings' activities and attacks become. In just three days, the beast kings' range of activity has expanded two or three times. In the former land cities, there are ruins everywhere after the beast kings' rampage, and some beast kings have occupied the cities, seemingly wanting to divide the world with humans.

Of course, not all countries can tolerate the beast kings' crazy provocations.

After continuously giving up four states, the European Union finally couldn't hold back and was about to launch a counterattack against the beast kings, but their counterattack was not like the missile bombers of the past, but a fully armed evolver squad!

This evolver squad claims to be the highest combat power cultivated by the European Union. They are equipped with the most solid nano protective suits and laser weapons, as well as alloy combat knives built with the most cutting-edge technology. Not to mention these people, just the equipment they wear is worth more than 500 million EU!

The EU's high-level officials believe that the evolver army exists to fight against the beast kings, so they must face the beast kings directly to truly develop strong combat effectiveness. It is useless to train in a greenhouse all the time!

This is the first counterattack by human evolvers against the beast kings since the world changed, and it has naturally attracted worldwide attention.

Not only the European Union, but even Russia and the Yanhuang Federation have sent bombers to escort this evolver force.

At this time, the contradictions between countries seem to have become unimportant.

This force consisted of fifty people. They set off from Texas, and after two hours of sailing, they came to a city that had been occupied by the beast kings. They descended from the sky and plunged into the beast tide with the hope of all mankind.

Then...

The entire beast tide was pierced through. Fifty people, after a battle that was not too difficult, defeated the beast kings and mutated beasts in a city!

After receiving this news, the whole world was沸腾 (fei teng - boiling)!

This performance by the European Union showed everyone the power of the evolvers.

Almost all of humanity is pouring all their resources into evolver research, abandoning investment in all other projects!

Everyone is vying to be first, afraid of falling behind!

The news spread back to Kuangxi Island.

Li Tianran sat on the sofa, looking at this news, touching his nose and said with some doubt: "How did the European Union make a group of atavistic evolvers so strong in such a short period of time? There are dozens of beast kings and thousands of mutated beasts in a city, and they were actually killed by them without the help of technological firepower? This group of evolvers' abilities are almost surpassing mine, aren't they?"
