[Primary exoskeleton: body, arms, legs, feet, connecting joints, active joints, elbow joint components (duralumin alloy X10, power controller X1, battery pack X1, power cord X10, copper ingot X15, strong cotton X5, rubber X1), precision electric actuator]

The complex materials came together, and after a flash of white light, they combined into a strangely shaped thing with a lot of straps and joints.

[You've obtained: Primary Exoskeleton!] 】

Seeing his old friend appear again, Lin Yue couldn't help but get excited.

The exoskeleton, the importance of this thing is self-evident, and after losing it last time, it really made itself quite uncomfortable.

Even, he was once forced into a desperate situation because of this.

In Lin Yue's current view, this thing can't be relied on too much, but it can't be without.

It should be used appropriately when fighting, but it should still be used when carrying heavy loads or other strenuous work.

People's physical strength and energy are limited, after all, when they come to another world, no one becomes superhuman, has infinite strength, and will not breathe fire and spit water or anything, inventing or discovering more labor-saving survival tools is the way to go.

But it is true that we should not waste ourselves because of this.

Lin Yue looked at the simple exoskeleton, looked at the various accessories on it, and finally found a lithium battery, 10 units of zinc alloy, and some fiberglass on top of it from the warehouse.

[Is it possible to upgrade the primary exoskeleton to the intermediate exoskeleton MK2?] Requires Universal Upgrade Design Diagram X3]

MK2？ Good guys, upgraded directly to the enhanced version of the mid-level exoskeleton, right?

It's even better, though.

In fact, he has long had some opinions about the "primary" on the original exoskeleton.

After all, the word "primary" in this "primary exoskeleton" can be lowered no matter how you look at it.

Who doesn't want to have some kind of "Excellence" or "Legendary" or "Epic" prefix on their gear?

It's not like that, but "Intermediate MK2" is pretty good

[You have obtained the intermediate exoskeleton MK2!] 】

A white light lit up again, and the exoskeleton in front of Lin Yue also changed significantly!

It's thicker now, with a lot more metal on it, as if covered with a layer of armor, and it's neat and straight, and it's very strong and designed.

The battery has been upgraded from the battery pack in the past to a lithium battery with a larger capacity, and the kinetic energy is also more powerful.

The joints and pedals are made of fiberglass instead of cotton, which is relatively more flexible and stronger.

Compared to the original one, the current one seems to be much more bullish.

Lin Yue immediately put on the exoskeleton, and immediately felt a completely different feeling from the previous one!

"Emma, this flexible seems to have grown out of her body, and it seems that her kinetic energy is several times stronger!" Lin Yue tried to lift a broken freezer on the edge of the warehouse, but it was unexpectedly relaxed, and he couldn't help but let out a sigh.

Not only that, the degree of flexibility is more than one grade higher than before, and the motor driven by lithium batteries makes it a powerful and agile weapon!

"It seems that now it can be stronger than before, whether it is carrying or fighting, but now only the bone armor is pulling the crotch."

Lin Yue took off the bone armor on his body and put it on the ground.

Although the bone armor is strong, it can't keep up with the upgraded weapons in the lizardmen's hands.

Its strength was originally able to defend against the attack of the stone spear and stone sword, and if it encountered the opponent holding a steel gun and steel knife, it was estimated that it could be cut down at close range.

Lin Yue felt that it had to be upgraded so suddenly.

"Upgrade...... Neither alloys nor metals seem to work, this thing is very light to wear, but if you use steel or something, it will become very heavy and limited in movement...... Wait, is it possible to use that? ”

Lin Yue walked to the warehouse outside and looked at the thing that had not been used all along, the insect beetle!

The giant beetle, though not pretty, was quite hard, at least much stronger than the bone carapace.

He had acquired it when he had killed the bloodsucking mother in the secret realm, and he was surprised that it was invulnerable at the time.

When he was finally burned to death by the fire, the worm beetle was finally retained, and then he put it in the warehouse untouched.

Can this beetle upgrade the bone armor?

Lin Yue picked up a piece of insect beetle, and was about to put it on top of the bone armor, but at a glance, he saw another thing that had fallen to ashes for a while not far away.

Poison Sky Dragon Armor!

Good guy, forgot about it.

Lin Yue didn't have any interest in insect beetles anymore, after all, the big insect of insect beetles was a little kid compared to Poison Tianlong.

When the Poison Sky Dragon had this carapace, he was not even afraid of fire!

If it weren't for his cooperation with Xiaobai and his continuous attacks, Poison Tianlong would really be difficult to deal with.

A piece of the carapace of the poisonous dragon was removed and placed on the bone armor, and the sound of the system sounded at the same time.

[Upgrade the bone armor to the Celestial Dragon Warframe, you need the intermediate universal upgrade design diagram X1]

Lin Yue: ???

What's that?

Need an intermediate universal upgrade blueprint? Is there an intermediate level in the universal upgrade design drawing?

Lin Yue glanced at the universal upgrade design plan he originally had, and felt that this was a bit of a joke.

There's an intermediate and beginner level for this thing.

He immediately clicked on the survival point mall, wanting to see how many survival points it would cost to get his hands on the intermediate universal upgrade design map, so he searched around......

"None? I'm in a hurry to upgrade, and you told me that it's okay if you don't. ”

Whether it is the Survival Point Mall, or the World Mall, or even in the group and the World Channel, there is no word about the "Intermediate Universal Upgrade Design Map" at all.

It seems that it seems impossible to upgrade to the "Celestial Dragon Warframe" for the time being.

It seems that we have to hope to open the treasure chest to get this thing.

Lin Yue could only retreat and put the insect armor on top of the bone armor.

[Upgrade the bone armor to a blood-bellied beetle, which requires a universal upgrade design diagram X1]

Fortunately, I didn't need an intermediate one, so I upgraded it.

Lin Yue immediately chose to upgrade this time.

Although it can't be upgraded to the Celestial Dragon Battle Armor that is very strong just by hearing the name, this Blood-bellied Worm Armor doesn't seem to be bad.

【You have obtained the Blood-bellied Worm Beetle X1】

Lin Yue saw that the gray-white bone armor on the ground had changed into a yellow-brown insect beetle with a harder texture, a tighter connection and a strong insect beetle!

"This thing is a little ugly...... Lin Yue looked at the color that was somewhat similar to "Ollie's color", and was a little dissatisfied.

The shell of the poisonous dragon is crimson, which looks quite domineering, and this blood-bellied insect is Ollie's color, which is also a worm, and the gap is a bit big, I said.

Lin Yue couldn't help but take the giant armor of the Poison Heavenly Dragon, and compared it with the Blood-bellied Insect Armor, he looked even more disappointed.

But without the design of the intermediate universal upgrade, there is nothing he can do.

Just as he was about to pick it up, his foot touched the Poison Heavenly Dragon Giant Armor that was placed aside, and it spun around twice and pressed against the Blood-bellied Worm Beetle.

[Upgrade the Blood-bellied Worm Armor to the Celestial Dragon Battle Armor, which requires a universal upgrade design map X2]

Lin Yue ??? for the second time

What's the situation!?

This time the upgrade doesn't need any "intermediate universal upgrade design drawing", just the ordinary one?

On what basis is this determined?

Lin Yue had a question mark in his heart, if it weren't for the fact that this poisonous Heavenly Dragon giant armor accidentally rolled down on the blood-bellied insect beetle, he really wouldn't have been able to find out about it.

"Wait, this means that it is not possible to upgrade the bone armor directly to the Celestial Dragon Armor, it is too much to leap, but after upgrading to the Blood-bellied Worm Armor, it is okay to upgrade the Celestial Dragon Armor, right? Or is it that the bone armor belongs to the beast bone armor, and there is a fundamental span between the insect armor, so a medium-level universal upgrade design plan is used? ”

Lin Yue guessed all kinds of possibilities.

He picked up the crimson Heavenly Dragon Battle Armor on the ground, and found that its thickness was about the same as the original bone armor, but it was inexplicably not as heavy as he imagined, but extremely light.

And after putting it on, he also found that this armor was breathable and fitted, and even if he used the excellent iron spear for a while, it could only leave a shallow trace.

"I remember this thing was originally fireproof?" Lin Yue remembered the scene when he fought with the Poison Sky Dragon, if it wasn't for the final explosion, the Poison Sky Dragon would not have been killed by him in the end.

So, what about the strength of this Heavenly Dragon Armor?

[Tianlong Battle Armor: Made of the shell of an extremely hard poisonous dragon, it is strong, breathable, lightweight, waterproof, anti-corrosion, fireproof, anti-bullet penetration, strong and extremely resistant]

Ahh

Isn't it just a "must-have for home travel" advertising slogan?

Just looking at the appearance and these characteristics, this thing is almost tied to the "artifact".

Lin Yue tried to put the "intermediate exoskeleton MK2" on the outside of it, and found that it fit perfectly.

"Yes, it's good to get your defense up all of a sudden."

Lin Yue said that he was very satisfied, and now he seems to have no shortcomings in defense...... Wait, can you change the helmet a little bit?

Taking out the bulletproof infantry helmet that he had been using before, Lin Yue followed the previous steps and quickly got the Bloody Worm Helmet, which was upgraded to the Tianlong Battle Helmet!

The characteristics of the Draco Helmet are exactly the same as those of the Draco Armor, and the overall appearance is also quite sharp, with a staghorn-like spike on each side of the helmet diagonally above, and the other parts are extremely smooth, covering all the important parts of the head except for the face.

And it also comes with a mask, if you wear it, it will only reveal a pair of eyes and breathing holes, and it will show an aura that looks like an ancient armor.

Lin Yue tried to put the helmet on his head, and found that it was also breathable and comfortable, and he was more satisfied.

This wave of blood is earned.

Wearing this outfit to fight the enemy is shocking enough just by looking at the appearance, and it also has many advantages, which is really good.

But then again.

If it weren't for becoming the ruler of Feiyue's refuge village, it would not have been so simple to have a robot dog so quickly and successfully make an exoskeleton.

And without this opportunity, I don't know when to upgrade my armor and helmet.

He felt that it was necessary to give Fei Yue the next task.

Alloys are no longer sufficient.

Recently, I've been using it more ruthlessly, and I've basically used some of it when making various things, so I've used up all the various alloys that I have been able to get with great difficulty.

The only alloy he had now in his hand was the steel he least wanted to use.

The steel was obtained by demolishing the Tokyo Tower at that time, but this thing, no matter where it is used, I don't think it's too useful, and because it rusts, Lin Yue doesn't want it to be the main body of the shelter, and if it does, maybe it will be used for wall construction or something.

After all, there are too many disadvantages of this steel, and there are indeed too few advantages.

For example, he never dared to use steel as a raw material for medium-sized food preservation and cold storage and a small food processing plant that had not been built because of the lack of alloys.

So at present, he is still quite short of various alloys in general.

Zinc alloy, duralumin alloy or something, how much you really want to receive.

As for titanium......

Lin Yue looked at the smelting furnace that had been abandoned at the door, and the iron and titanium ore piled up in the corner of the warehouse, and shook his head.

He didn't have the fuel needed for the smelting furnace, and he didn't have a clue how to turn iron and titanium into titanium alloy.

At present, this aspect is stuck, and there is no way to move forward.

Unless you can recognize some big boss in smelting, you won't be able to do something for a while.

If he can really get titanium alloy, he can also change the shotgun to the gun, and really bring the current technology into the high-tech category.

Think about it, what titanium shelters, what titanium alloy thermal weapons, what titanium alloy walls, tools, all kinds of buildings......

If you can drive any rocket spaceship, you can give titanium alloy a once.

"No, we still have to collect some alloys, and first cover the medium-sized food preservation cold storage and small food processing plants, and it will not work to drag them all the time."

Lin Yue immediately contacted Fei Yue again.

"Fei Yue, when you go to the secret realm, look for more alloys and the like, 2 units of alloy for 1kg of vegetables, no problem, right?"

After the message was sent, Lin Yue did not wait for Fei Yue's immediate reply.

Maybe I've already entered the secret realm.

He opened the World Exchange Mall and browsed it.

There are real ones who sell alloys.

After the system upgraded the trading panel to the World Trading Mall, an obvious change is that the variety and quantity of things sold have increased exponentially.

He also found that there were more than a few people selling water.

It seems that after this disaster, everyone has a large stock of water.

However, Lin Yue also found that many people did not sell rainwater, but underground river water or even pure water.

It seems that, except for the group he is in, the other groups are not as short of water as they imagined.

There are really a lot of people who sell alloys, and there are all kinds of varieties.

Lin Yue searched, used some vegetable resources to quote some more suitable asking prices, and soon reached a deal.

[You have obtained stainless steel X3, manganese steel X4, bronze X2, white copper X11, duralumin alloy X3, zinc alloy X2]

There are not many quantities, but there are many varieties.

Lin Yue was not satisfied, but the rest either raised the price or was outrageously high.

He placed his own resources on the trading panel.

Vegetables, fruits, wine, and whiskey, change alloys!

And, as before, in the form of a quote.

Lin Yue felt that it was necessary for him to know if the people in the world needed these more than those in his original group.

And just as he was about to close the system panel, he looked back at a big guy in the warehouse.

"What can you get for a private jet?"
