"Light curtain!"

"Tu tu tu tu!"

The red light on the surface of Li Jun's skin was able to withstand small-caliber pistols.

Of course, this requires him to be extremely focused.

The light curtain cannot be maintained for a long time, and if someone secretly conducts a sneak attack, it will still not be able to withstand bullets.

"I don't know what the effect of level four is..." Many researchers discussed incessantly.

"According to the information passed back by Instructor Lu, level three to level four is a very big threshold. No matter how talented you are, without a lot of resources, it will take several years, even decades."

"That was indeed quite a long time."

"If everyone cultivates to a higher level, the legendary world of martial arts will be like this..."

There are still mostly young people in the institute, and everyone is beginning to think about the future.

However, some people are happy and some are sad.

Young people can think wildly, and those who are in charge of the family will be so worried that their heads turn gray.

Zhang Hui, the general manager of the institute, sighed in his heart: "From level 2 to level 3, a lot of resources have been consumed."

"But the resources in the institute cannot support one person infinitely..."

What's more, extraordinary level is related to life span, and the principle of not worrying about scarcity but unevenness is the same in any society.

"The qualifications of ordinary people are not high enough. Even if they practice to level 2, they still need some extraordinary resources... Sigh... If the level gap is too big, everyone may have conflicts."

He looked at the peach tree in the research institute...

Well, it’s just as thick as an arm.

One tree wants to support the entire city’s cultivation resources?

How whimsical!

…

After testing like this for more than an hour, Li Jun was a little tired and wiped his sweat away, with indescribable excitement on his face.

Of course, he knew that his various statistics were still not as good as Lu Yuan's.

When Lu Yuan contacted the lizard people, humans already knew that Lu Yuan was a master of extraordinary level 3.

Now...it should be at least level 4.

From a certain perspective, having a stronger person suppressing you is not necessarily a bad thing.

At least, it gave everyone the motivation to catch up.

"I will continue to work hard and move towards higher goals. I will strive to practice to level 4 as quickly as possible!"

"What a great ambition." Zhang Hui smiled bitterly, "Level 4 requires the opening of meridians. We have to find ways to study this matter."

With the information sent by Lu Yuan, the road ahead is almost smooth. They just need to practice step by step.

The only problem is resources...

The resources are really too few and too barren.

After resting like this for a while, Li Jun suddenly stood up and said seriously: "Professor Zhang, since I have reached level 3, I must organize people as soon as possible to conquer that sycamore tree!"

"I will find a way to solve the problem of insufficient extraordinary resources."

Zhang Hui nodded: "You go ahead."

Yunhai City selects the strongest geniuses among 10 million people and invests a lot of resources. Naturally, it cannot be just to look good.

Twin sycamore trees, a mysterious big tree - Yunhai City's current biggest opportunity and biggest challenge!

…

After Li Jun left, the screen of the contactor lit up and made a "buzzing" vibration sound.

Communicating with international friends is also a basic daily routine in the institute.

"Hello friends, we have some good news today." Zhang Hui briefly revealed that the progress in Yunhai City has attracted the envy of other cities.

The gap between cities has widened rapidly in the past six months.

For example, spreading extraordinary fire requires organizational capabilities, and it took Yunhai City more than a month to complete the full spread of the population.

But in most cities, even after half a year, it has not been fully popularized. Some cities with serious corruption even regard spreading fire as a privilege.

There are other cities...

No fire…

Several professors in Dongjincheng feel heartbroken when they think that others can live for hundreds of years, but they will die of old age in a few decades.

It's really painful to see others keep taking the lead while I'm standing still...

Of course, there are also a few cities that can keep up with Yunhai City.

"Congratulations... Our Captain Smith here has also reached the limit of Level 2 fire. He should be able to break through to Level 3 in the next few days." Professor Edward from New York City, the Sixth Civilization Branch, said with a smile.

"From this point of view, six months is almost the maximum speed at which the human species can reach level three with the investment of a large amount of resources."

"That's right."

"Since it takes six months for those with the best talent, it may take decades for those with less talent, or even until death, and there is no way to break through to level 3."

Zhang Hui nodded: "Yes, the resource problem is imminent."

Using resources to build a level 3 warrior is actually not a very technical matter - after all, the road ahead is smooth, so what else can be difficult?

It is difficult to popularize it among the people. After 6 months, there will only be a hundred or so level 2 warriors, all of whom are top talents.

But even though they have talent, they don't actually enjoy many resources, so their progress is naturally slow.

At this rate of development, even if it takes several hundred years to develop, a dozen or so level three and one or two level four experts would be the limit - this outcome would be no different from the Meda civilization.

"If human beings want to develop greatly, they still have to leave the safe zone and enter Pangea."

But before leaving the safe zone, you must first defeat that dark cloud, that is, the [demon].

As a result, everyone discussed the recent industrial development and resource status.

This can be considered a daily routine, everyone should supervise each other, and the crusade plan must be carried out as scheduled!

Things are actually going quite smoothly in Yunhai City. In just half a year, several power stations were built to continuously provide electricity.

Large hydropower stations are also being steadily constructed.

After the industrial production capacity gradually recovered, it began to tilt towards the military direction.

The quality of life among the people is a little worse, but as long as it is passable, it will be fine.

As for other cities... there is actually no way to conduct on-the-spot investigation, and it is not clear whether it is true or false.

Like Ping An City, the war is not over yet, and there is only a little sporadic news so far.

The minimum requirement that humans have for them is: don’t cancel the safe zone randomly! As long as you don’t lure the [demon] there, you can fight them as long as you want.

Another example is cities like Cape Town, where warlords are still fighting.

But Cape Tun is also very important. A mineral vein called "Diamond Crystal" was discovered there, which is a kind of spiritual energy that can be used in industry!

And Old Delhi...

"We in the three countries of India are well-trained and experienced in restoring production capacity. Whether it is a high temperature of 40 degrees Celsius or a low temperature of minus 20 degrees Celsius, our workers have a high degree of professionalism and willpower in any situation."

"So you don't have to worry! We are developing a large missile with high accuracy and can produce huge explosions." The brown-skinned old man kept boasting and making sure of it.

"We are confident that we will defeat our opponent within 24 hours."

Professor Zhang Hui always feels like he is bragging.

Hey, will this missile explode halfway? God cannot know the answer.

Of course, there are also a few cities that have actually done something practical.

For example, Tojin City, which is the most enthusiastic, is building a "Super Suspended Fortress", and they have sent detailed videos and photos - a war weapon that uses extraordinary items to levitate in the air.

Its tonnage reached five million tons!

A veritable behemoth.

Zhang Hui actually doesn't like the people in Dongjin City very much, but this floating fortress is indeed very important.

Sydney City is doing something similar, with a smaller fortress as a future war tool.

There is also the main force against the [demon], Lingbo City, which is also frantically producing weapons and equipment.

The spokesperson of Lingbo City, Digdit said: "We are engraving temperature control glyphs on a large scale. I also hope that all friends can implement the next plan down-to-earth! This is related to the future of all of us!"

As for the glyph technology... it has also made pretty good progress.

After all, mathematics is ready-made knowledge for all major scientists, and there is no need to learn it from scratch.

In major cities, there are also a few talents who can carve seals and engravings.
