On the other side, Gu Younan was also thinking about the direction of his strengthening.

As of now, he has two core skills, one is the [Eight Steps to Catch the Cicada] LV4 that increases movement speed and flexibility, and the other is the [Reconnaissance Technique] LV4 of Perception and Detection; These two skills, although they are only silver ratings, are very practical and can greatly improve Gu Younan's survivability.

Especially the [Reconnaissance Technique], within the coverage area, it seems to open the perspective of God in the whole picture, and every move of the enemy cannot escape his perception.

If it weren't for the existence of this "magic skill", he would have been killed by a sneak attack by a hostile contractor in the [Killing Mission].

Before the [Killing Mission], he had 10,000 Heavenly Points and 6 Free Attribute Points left on his body.

After returning from the bloody battle on the battlefield of "eating chicken"; After killing the enemy contractor and leveling up, plus the task reward, he gained another 5,000 Heavenly Points and 90 Free Attribute Points.

Counting the 15,000 Heavenly Points that Nie Zhi gave him just now, he already has 30,000 Heavenly Points and 96 Free Attribute Points.

With so many Heavenly Points, he also had a bold idea, that is, to buy an energy source.

In the real world, the biggest technical obstacle for heavy individual mechs is the energy source!

At present, all heavy individual mechs in the real world use rechargeable batteries.

Although some countries put their own rechargeable batteries, the name of "high-energy batteries".

But no matter how loud its name is, in essence, it is still out of the range of non-nickel-cadmium, nickel-metal hydride, and lithium-ion batteries.

These three battery structures, no matter how optimized, cannot break through the inherent chemical limits.

Therefore, a heavy individual mecha of more than 400 kilograms has hundreds of kilograms just for the power part plus the battery.

Moreover, these rechargeable batteries, even on a full charge, can only last up to 80 kilometers.

This is basically the limit of what real-world technology can reach.

If we can break through this limit, find a more compact and durable energy source.

Then, the combat effectiveness of heavy individual mechs can immediately have a qualitative leap.

The best energy source, and the closest energy source to the level of technology in the real world, is the world of "Iron Man". Stark's homemade small Ark reactor.

This thing has to be sold in the Heavenly Divine Appreciation System area.

In the past, Gu Younan had a low military rank and was not qualified to buy, but now, he has reached the rank of sergeant and finally has the qualifications to inquire.

However, after inquiring, the ultra-high price of 100,000 Heavenly Points simply poured him cold.

This is also the lowest first-generation palladium element ark reactor; The price of the more advanced second-generation Ark Reactor has reached 200,000 Heavenly Points, and the most advanced new Elemental Reactor has exceeded the price of one million Heavenly Points.

With such a high price, I really can't afford to sell iron!

Looking at the series of zeros behind the number one on the selling price, Gu Younan's face changed, and he finally made up his mind.

Saving!

Desperately save money!

Even if it's suffocating! You must also hold back 100,000 Heavenly Points.

Be sure to buy a miniaturized Ark Reactor!

Only this kind of super energy source with high output and small volume can create the ideal steel armor.

Otherwise, with the level of science and technology in the real world, I don't know how many teenagers I have to have to realize the dream in Gu Younan's heart.

Gu Younan, who was unwilling, had no choice but to save all the 30,000 Heavenly Points.

Start strengthening your basic attributes.

First of all, perception must be added; Secondly, carrying a heavy individual mecha weighing hundreds of kilograms, the physical strength and strength must also be very strong; So, let's add these three attributes.

At the moment, Gu Younan has added 24 free attribute points to his perception, reaching 59.

The reason why no more points were added is because once you break through the [Extreme Barrier] of 60 points, you must perform the [Breaking Extreme Mission] within three ordinary missions.

After completing the [Breakthrough Extreme Mission], you must change your binding to the main world.

At that time, without the strong support of the real world for him, his mecha enhancement stream would be even more impossible.

strength, he added 30 points, which met the minimum requirements for the use of [Iron Slashing Heavy Sword]; 45 points.

Although he has the support of a heavy individual mecha, his strength is high enough that he can practice using this heavy sword in peacetime.

Stamina, he added 17 free attribute points, reaching 40.

Finally, I thought about it;

In terms of agility, he also added 15 attribute points of his own, reaching 40.

In this way, after spending 86 free attribute points.

His basic attributes, have become;

Stamina: 40+5

Strength: 45+20

Dexterity: 40+21

Perception: 59

Charm: 15

Spirit: 14

With such an average attribute, although there is no burst bonus of [Extreme Talent], there are almost no weaknesses; Piloting a heavy individual mech again will also be more handy!

Realizing that his body had become much stronger again, Gu Younan secretly decided that when he went back this time, he must use the strongest materials to tailor a more powerful set of heavy individual mecha, and then with the [Iron Chopping Heavy Sword], he will definitely be able to sweep the entire difficulty!

After the reinforcement was completed, he walked out of the skill enhancement center and happened to meet Nie Zhi, who had also been strengthened.

Seeing his sullen expression, Nie Zhi asked the doubts in his heart.

At first, Gu Younan was reluctant to answer, but under the torture of Nie Zhi's serious eyes, he still expressed his distress.

I heard that Gu Younan wanted to buy an energy source, but the Heavenly Points were insufficient.

Nie Zhi laughed and patted him on the shoulder.

said: "Isn't it 70,000 Heavenly Points?" Bring a few more [JS05 tactical sniper rifles] and a few more sets of [Special Operations Full Armor], sell them all, and make up again, isn't it enough? ”

Having made up their minds, they chose to return to the real world together.

In an instant, the scenery changed, and they returned to the RV where they entered.

Only this time!

As soon as he came back, Nie Zhi's whole body involuntarily trembled violently, as if there was an invisible huge force that strongly rejected him and wanted to squeeze him out of this world!

At the same time, his contractor's mark also came with a series of warnings:

"Respected contractor, your strength has far exceeded the limit of what this world can accommodate, and you must choose to 'change the main world' as soon as possible! Countdown to change: 72 hours! ”

"Respected contractor, your strength has far exceeded the limit of what this world can accommodate, and you must choose to 'change the main world' as soon as possible! Countdown to change: 72 hours! ”

......

Random, bright red "Rebind Overworld" option that pops up automatically!

An indescribable, maddening, and strong impulse instantly filled Nie Zhi's brain.

Choose New World! Get out of here, out of this poor lowly world! ”

"Let's go, in the "New World", there are countless treasures and countless women, waiting for you to plunder, hurry up and go! ”

"Do you yearn for freedom? Yearning for killing? Get out of here and head to the "New World"! You can slash and slash at will! Freedom to run amok! Your strong strength will not be wasted! ”

......

Voices full of temptation kept ringing in his ears!

One by one, the thoughts of killing and desire were churning rapidly in his mind.

In this extremely difficult situation, Nie Zhi worked hard to stick to his original heart and struggled against the powerful temptation of "changing the main world".
