The borrowed endoscope was housed in a leather case, connected by a cable, resembling a large thermometer gun with a screen. At the time, the screen resolution wasn't high, it was just blurry.

Lay the head of the iron tower flat, drill a hole along the edge with a drill bit, and then keep drilling in. At first, it's not easy to do, often slipping. The drill bit just needs to go down a little bit, and it gets much better.

The Ayutthaya Tower, the base of the tower is about 7 centimeters thick. It was slowly ground in with a drill bit, taking over three hours to complete.

I heard a sudden screech of the drill, which meant the bottom of the tower had been pierced. As I guessed, the middle was empty.

He wiped his brow and said, "Mai, straighten the thread and see if it can go in smoothly."

">

Little bean sprouts said okay, he straightened the thread and pushed it in little by little.

"No way, this thread has a little light on it, my eye is too small, it's stuck," said Douzi as he tried to force it in.

He rubbed his head for a long time before successfully threading the wire.

"How's it going, Yunfeng? Does it work?"

I adjusted the brightness and looked at the screen, a little over two inches, and said, "It works, there's an image."

“ The content within the tags has been translated to English:" "

Gather the head and Xiaoxuan over here to take a look.

Through the endoscopy, we saw the interior of the tower. It turned out that three iron rods were inserted horizontally under each section of the tower body. This should be to strengthen the tower body's load-bearing capacity.

Stuff it in, little sprout. Give it a bit more effort.

"I commanded," I said.

The bean sprouts are being stuffed in again.

>Stuck again.

"Doudou said."

I looked at the small screen and said, "You're next to the iron rod, pull it to the left."

Okay, let's go.

""

I directed the bean sprout to thread the endoscope wire through the gap between the three iron rods.

"Huh? Wait a minute." He stared intently at the mirror screen, his head still. "What's this thing?"

I stared suspiciously at the small screen on the mirror, where a scroll-like thing lay horizontally across three short iron bars. Due to the low resolution of the screen, it was somewhat blurry, but from the color it looked yellowish-white.

"Paper?? "

"Not a Tangka, not a Nine-Eyed Sky Pearl?"

"A scroll from Xi Xia? How could it have survived?"

Looking at the small screen, he said with uncertainty: "It's hard to say. Kozlov took a lot of documents from Heishui City back then. Isn't that copy of 'Fanhan Heshi Zhangzhongzhu' in the Ur country museum just a paper Han Chinese-to-Xixia script dictionary?"

The little sprout leaned his neck to look at the screen, "Damn it, we're screwed! Just a small roll of paper! We lost big time!"

I gritted my teeth and directed Dou Zai to continue sending the line upward. We reached the top of the tower, but found nothing unusual.

I asked the "head," "Does our shaking of the tower body come out as a sound, can paper make a sound?"

He shook his head, saying he didn't understand. He had to take a look at this thing.

We found a wire and bent the front end into a small hook. The little bean sprout used the wire to poke at it, slowly pushing it to the edge.

"It fell down!"

"I can't get it out!" said Douzi in a hurry: "The hole is too small! I can't get it out!"

If they had all gotten to this point, they either took out the item unwillingly or couldn't bring themselves to do so. They then used a drill to enlarge the hole again.

I was sweating just watching this, how is such a big hole supposed to be repaired? What if the buyer, Liu Yuanning, finds out and doesn't want it anymore?

When we looked, it turned out that it wasn't paper but a small piece of something like sheepskin. Because it was very thin and had oxidized and changed color, it looked like paper.
