"My arm was injured, and although I was coated with powder, it would take at least a day to return to normal movements." Xu Wen took a night's broth and handed it to him.

Although the medicines in the world are much more advanced than those in the original world, it is not so easy for Lin Xiu to recover from that kind of wound.

"Thank you." Lin Xiu took the bowl of the Evolution Beast** boiled**, and couldn't help but bite the meat pieces like jujubes, and drank the soup.

The sweet soup and the elastic pieces of meat made Lin Xiu lick his lips, a little unsatisfied.

It didn't take long for them to rest, and after a good rest, they decided to set off again on the 'cleanup' mission

"Your ...... injury" Seeing Lin Xiu regain his grip on the Silver Soul spear, Li Yi said a little worriedly.

"Out of the way." Lin Xiu shook his head, the wound had healed now, as long as he didn't exercise vigorously, the wound wouldn't collapse.

And he didn't want to drag his feet either.

"Okay." Xu Wen nodded, if he wanted to wait for Lin Xiu's wound to recover, it would probably take too much time, and seeing that Lin Xiu didn't have any major problems, he continued to lead everyone to continue to walk forward.

The zombies here have been almost cleaned up by them, and it is estimated that only the zombies in the corner have not been cleaned up.

"If you throw a nuclear bomb down, all the monsters here will be destroyed, so why bother to clean up." Li Yi said with a wry smile at this time.

After resting for the night, I have to continue to face these monsters, and I really think of those hideous cheeks, which makes people feel a little numb in the scalp again.

"Do you think this place hasn't been cleaned with a nuclear bomb?" Lin Xiu stood in the middle and couldn't help but smile.

"What do you mean?" The rest of the soldiers all looked at Lin Xiu curiously.

They really didn't know that the A20 area had been cleaned up by dropping nuclear bombs.

"In the depths of A20, the federal army used nuclear bombs to 'clean up', which turned a city into ruins, but the monsters did not die completely because of this, and many of the remaining monsters became more terrifying because of the nuclear contamination."

"Our current position is only a marginal position, and the instructors should go deeper into the area."

Although the knowledge textbook for the A20 area is very vaguely not mentioned, Lin Xiu still gained a lot of knowledge in this area from other aspects.

Although Lin Xiu was a waste wood before, it really goes without saying that he is a living and walking encyclopedia in terms of knowledge.

"So that's ......" Li Yi couldn't help but feel palpitations when he heard Lin Xiu's words, a monster that can't even kill a nuclear bomb, how strong is this.

When you imagine it, you feel scared.

As you walk forward, the style of the surrounding buildings seems to have completely changed in an instant, and it is completely different from the one you just started.

The houses here have a lot of gears and are very mechanical.

There are also a large number of flattened or rusty machines around.

On the other side ahead, there is a long railroad track, on which there is a steam train broken into several sections.

"My obedient ......" Li Yi's eyes couldn't help but widen when he saw this scene, and he looked very surprised.

"In the year 2701, during the war with the alien invaders, there was a special era of retro steam machines, using isomorphic energy as a new energy source to build all kinds of machines." Lin Xiu looked at this scene, and this information quickly appeared in his mind and said it.

"I see." Xu Wen nodded, and then looked around curiously.

Stepping on the ground, a lot of scrap metal made a clicking sound, and then cracked.

"It should be a certain age." Lin Xiu looked at the surrounding scene and couldn't help but muttered to himself.

There are still some abandoned weapons around, long swords and machetes, but the bodies of those weapons seem to be made of some gears, and they look extremely weird.

He picked up a long sword, and saw a depression above the hilt.

"What kind of sword is this?" Li Yi looked at this kind of sword with a large number of gears in the body of the sword, some small and some large, and there was also a strange machine structure, as if it was a mechanical sword.

Looking at this strangely styled weapon, he couldn't help but widen his eyes and look at it carefully.

"Is there any isomorphism?" Lin Xiu said aloud.

"Yes." Xu Wen didn't think much about it, and directly threw out a strange crystal, which was hunted and killed this morning when Lin Xiu hadn't woken up yet.

Lin Xiu turned out that strange crystal, and it was cold for a while, this abnormal crystal type was not big, but it had a heavy feeling.

After thinking for a moment, Lin Xiu put the different crystal into the groove above the hilt of the mechanical long sword.

Just the right size.

Looking at Lin Xiu's movements, everyone around them looked at this scene curiously.

Click-

Behind the mechanical long sword, there was a button that could be pressed, and with Lin Xiu's press, the gears on the sword body began to slowly rotate for a while, making a gurgling sound.

"It's moving!" Li Yi exclaimed.

Soon, the gears seemed to spin faster and faster, and in the next second, a white light began to emanate, enveloping the blade of the mechanical long sword.

"This ...... What is it? A soldier couldn't help but open his mouth wide in surprise when he saw this scene.

It's just amazing.

"A weapon made with isomorphism as a driving energy source." Lin Xiu said lightly, and then gently slashed a piece of iron next to him with a long sword.

Hiss –

A strange sound rang out at this time, and at the same time, the steel slashed by the mechanical longsword emitted white smoke and left a deep crack.

"It's pretty sharp." Xu Wen looked a little surprised, the sharpness of this machine long sword was already able to reach the weapons made of high-grade materials.

With his own sword, it is estimated that he will not be able to cut a crack on this iron block so easily.

It's like slicing white tofu.

With a "click", as Lin Xiu pressed the button again, at this moment, the mechanical long sword that was spinning wildly stopped spinning at this moment.

The light that emanated from it also disappeared in an instant.

"Although the power is good, it is too consuming of isocrystals, and this kind of mechanical process seems to be a heavy work, and it was eliminated a hundred years ago." Lin Xiu looked at the obviously smaller heterocrystalline placed in the groove, and couldn't help but shake his head and said.

That period of steam was only a special period created during the battle with alien creatures, and it had to be eliminated in the end.

However, according to historical records, during that period, there were also many machine giants with extremely strong combat effectiveness, and if you can find that kind of complete product, it will really be a treasure.
