Lin Yi walked up to the iron rod and found it was about as thick as a thumb, with a lot of dust on it.
What caught Lin Yi's attention was that this was something immortal.
There might be some kind of record on it.
"Come on, lend a hand and move these big stones aside."
Lin Yi called out, and everyone came over to help.
The rubble pressing on the iron rod was cleared away.
After extracting the iron rod, they found it was over ten meters long, exceptionally smooth, with no records on it.
Holding the iron rod, he found it quite hefty.
Lin Yi took out a dagger and chopped at it several times.
The dagger had a nick, but the iron rod in his hand was unscathed, not even leaving a mark.
Then, Lin Yi took out a scalpel, which yielded results this time.
It felt like both materials were of the same substance.
"Any new discoveries?"
Jiang Zhengnan came over and asked.
"Nothing at all, but this alloy cannot be manufactured with today's technology."
