End of the World: My Items Can Be Upgraded Infinitely

"Lin Feng, lv7/9"

"HP 40, PH 35, SP 36"

"Newly added cross-level ability: God Arm lv11/19"

The basic physical attribute data did not change much, and Lin Feng focused on his arms.

Under the stimulation of the heat flow, Lin Feng's arms have been completely repaired and healed, and even became stronger. When he exerted force, the outer layer of carapace would bulge slightly.

So much so that Lin Feng wanted to pull out the God-level pistol now, use the metal storm attribute, and shoot as much as he could.

Unfortunately, the amount of spare bullets that were still being restored, as well as the many survivors around, made Lin Feng stay rational and suppress his eagerness to try.

After learning about the outside world from Ding Chenghai, Lin Feng glanced at his mobile phone. There were still more than ten minutes before the rescue arrived, so he told the two women, returned to the window of the rooftop, and jumped back to the corridor on the tenth floor.

Pulling out the lv7 God-level pistol, he now has a pair of God Arms, which can use super-high firing speeds at will. Even if there are more red beetle swarms, they will be shot.

Walking in the corridor with broken limbs, Lin Feng no longer saw the insect tide gathering. Killing more than 150 red beetles has defeated this small insect tide.

He looked at the gun in his hand:

"God-level pistol lv7/9, white quality"

"Upgrade points: 88/10, damage 25, effective range 1000 meters, remaining bullets 1800/2000"

Killing 150 red beetles, the upgrade points obtained are far less than Lin Feng expected, because many bullets did not cause 25 points of damage, especially the bugs below lv4, which were basically killed by stray bullets and not counted.

But 88 points are enough for Lin Feng to complete the subsequent upgrades, but I don't know if he can directly break through the upper limit of lv9 and enter the next field.

Lin Feng suspected that the soldier bugs Ding Chenghai mentioned were powerful beings above lv9, with such a high degree of evolution that they were not afraid of rifle bullets at all.

When facing this kind of monster, the army needs at least one firepower reinforcement squad to work together to solve it. From the tone of Fatty Ding, the number of this kind of soldier bugs far exceeds the total number of the federal army...

If you want to successfully collect enough supplies in Haicheng, you must become stronger as soon as possible and have the ability to kill soldier bugs alone!

Lin Feng directly started the upgrade of the god-level pistol, and at the same time walked to the pile of red beetle corpses, looking for the back armor materials that can be absorbed into the shield.

Soon he collected more than a dozen intact back armors.

Putting down his backpack and taking out the tools he brought, Lin Feng used the god-level pistol to penetrate a red back armor, and then made it into an upgradeable item.

After three or four minutes, Lin Feng's red armor shield was finally upgraded to level 7:

"Red armor shield level 7/9, white quality"

"Durability: 10/10, defense 35, variant form: back armor (unconditional), shield armor (12h/1 back armor), new variant form: absolute defense (1/1 back armor)"

A total of fifteen pieces of back armor materials were consumed, and it was finally upgraded to level 7 and obtained a new form. Lin Feng melted in five more upgrade storages as a backup.

Then he tried the new form, and the next second, the shield armor on his body suddenly emitted red light, and then formed a light red semicircular cover within a five-meter range around him.

The protective cover showed the form of energy fluctuations, not physical matter, and only lasted for ten seconds before it dissipated instantly.

During this period, Lin Feng tried with a long sword, and he could pass through it if he slowed down, but it would get stuck if he chopped it quickly.

What's even more bizarre is that when Lin Feng tried to shoot, the bullet with great penetrating power stopped on the protective shield and could not penetrate it.

Such a rule, in Lin Feng's cognition, only one kind of substance has similar phenomenon.

That is non-Newtonian fluid, a fluid form that can absorb softness but not hardness.

But the energy shield must be more than that simple. It protects itself and its companions at critical moments.

It's just that the price is a bit high, and one upgrade reserve is consumed in ten seconds.

After the experiment, Lin Feng used all the remaining back armor materials on another new red armor shield, upgrading it from lv2 to lv6, and storing five back armors at the same time.

With the upgrade, the back armor form becomes smaller and smaller, and the time to maintain the shield form becomes longer. lv7 is 12 hours, and lv6 is 6 hours.

The new shield is prepared for Sister Yu Rou. Lin Feng is afraid that the lv4 red armor shield in her hand will not be useful. As for the new form of lv7 absolute domain, it involves incomprehensible things and cannot be leaked for the time being.

He knew very well that the secret of the production of the red armor shield would be revealed after Zhang Yurou returned.

This kind of multi-form shield armor, which is both lightweight and has extremely high defensive capabilities, will definitely be widely sought after and even mass-produced on a large scale.

Lin Feng did not want to expose more of his secrets, but to a limited extent, he still had to support the human resistance and not lose too quickly, so as not to put himself in a desperate situation surrounded by enemies.

In addition, the personal safety of Yurou's sister-in-law must also be guaranteed. Even if the shield armor is a gift left by Lin Feng for her, he will hand it over to the Federation and exchange it for some physical rewards, but in her hands, it means more benefits and power.

Mass-produced shield armor can also make Lin Feng less conspicuous and recognized by others.

After comprehensive consideration, Lin Feng wore a brand new red and silver shield armor, holding a small shield, returned to the rooftop, and came to Zhang Yurou.

"This is a more advanced shield. Replace it with the one on you. It can maintain the shield armor form like mine for about 6 hours each time and can be used five times."

"After arriving safely, we can organize professional technicians to study and see if we can figure out how to make it. Anyway, there are a lot of materials on the battlefield."

Zhang Yurou took the lighter and smaller shield, and quickly understood what Lin Feng meant. She walked up and kissed him deeply.

After a long while, they reluctantly separated. She held Lin Feng's cheeks with both hands and said softly:

"After escaping Haicheng, remember to contact me. If you need anything, just ask. I'll wait for you in Gangcheng."

Lin Feng smiled slightly and urged her to change quickly.

Zhang Yurou took off her coat and took out the lv4 back armor from her back. It was very convenient to put it on the back. You only need to reach out and press the button on the side waist to wrap the whole body in an instant, forming a layer of shield armor protection.

Putting the advanced shield armor in Lin Feng's hand into her back, Zhang Yurou shivered, put on her sun protection coat, and then handed the lv4 back armor in her hand to Chen Yanyan beside her.

After receiving the carapace, Chen Yanyan showed a hint of joy, looked up at Lin Feng, and saw that he smiled and did not object, so she followed the actions of sister-in-law Yu Rou and stuffed it into her back.

She felt safe all of a sudden.

Some of the other people on the rooftop saw this scene and showed expressions of surprise and confusion. Only a few people guessed something and watched with a hint of envy.

Among them were the knife-wielding girl Liu Yueqi and her future uncle Zhang Xuan.

As the leader of this group of teachers and professors, Zhang Xuan was not only young and charming, but also very good at manipulating people's hearts. It only took him one day to design and use giant insects to kill the previous director of the hospital. Then, relying on his selfless proposal, he quickly became the backbone in the eyes of everyone.

At this moment, he naturally saw that Lin Feng's group was not ordinary, and he was a little annoyed in his heart. Why did he say it so absolutely just now...

But this guy with a gun really survived the insect tide.

Fortunately, he dragged everyone into the water. Everyone stood on the opposite side of them. No one could wipe their face and approached to ask for advice.

And he only needed to contact Chen Yanyan to have a chance to get Lin Feng's secret, and then encourage everyone to hand over the pistol or armor.

Within a few minutes, many strategies were planned in Zhang Xuan's mind. It was easy to deal with this young man in his early twenties.

It's a pity that his thinking logic has not yet changed from the order of the peacetime era.

Just when everyone was thinking about their own things, there was a sound from the distant horizon.

Everyone stood up from the rooftop and looked into the distance. Soon, a black dot appeared in the western sky, which was getting bigger and bigger, and finally revealed its true form.

That black dot was a helicopter!

Everyone cheered and jumped for joy. Even though they were exhausted after a long night, they burst into vitality that they had never had before.

However, Lin Feng, who had some knowledge of military affairs, quickly recognized that this helicopter was not a rescue helicopter, let alone a transport helicopter. It was slender, with many weapon mounts on both sides, and a 20mm caliber machine gun on each side of the cabin...

This is a federal multi-purpose armed helicopter!

While everyone was cheering, Lin Feng calmly took the two women to the communication equipment.

Ding Chenghai sighed and shook his head:

"I guessed it right. The Zerg has probably sent out air units, so the one that came is a Wu-10 helicopter. Ordinary transport helicopters may not be able to protect themselves."

Afterwards, he talked to several engineering professors and asked them for a small communication device, which was only the size of a palm and had an old-fashioned black and white LCD screen.

Ding Chenghai handed it to Lin Feng, his expression solemn:

"I'm really sorry, I can't take you away."

"This is a signal receiving decoder, which can only receive specific frequencies, but the receiving range is extremely wide. I will inform you of the latest research information from time to time."

"Come on, Lin Feng, I believe you can escape. Remember, the further inland you go, the safer it is. I'll wait for you in the northwest!"

Lin Feng took the communicator and nodded solemnly:

"Don't worry, I'm the only child in the family, it's not that easy to die!"

After that, the helicopter also locked onto everyone, arrived above the rooftop, hovered for a while, and dropped two lifting ropes.

In the strong wind, two fully armed black-clad special forces members were roped down.

As soon as they landed, they raised their large-caliber guns, pointed them at everyone, and shouted through the loudspeaker:

"Don't come around!"

"Go up if your name is called!"

"The first one, Ding Chenghai!"
