At the same time that Lin Chi returned to the safe house with Zhen, the master engineer and an excavation team led by him, under the protection of the soldiers of the trapping regiment, arrived at the forest where the ruins were found.

"This is it."

Staring at the sickle and hammer pattern that was faintly visible on the wall, the middle-aged man standing upright and heroic, reached out and stroked the pattern he had never seen before, and whispered his speculation:

"Is this ...... Produce warehouse? ”

He had also excavated ancient ruins before, and found some strange metal and glass objects inside, but after some research, he could not decipher what they were, and finally had to put them on hold for the time being.

However, judging from the orders sent by the lord, it seems that they value the appearance of this ruin, and they demand that they immediately excavate and create an entrance to the underground ruins.

"Commencement." The master engineer said coldly.

The workers, who had just been transferred from the canal, quickly got into the groove and began digging up the dirt at the entrance to the underground ruins.

The shovel in their hands soon hit the solid metal "wall", and the workers cleaned the rubble from it, revealing a closed dark metal door.

"Do produce warehouses need this level of protection?"

Stepping on the indestructible metal door, the master engineer looked at the crack in the center of the metal door and ordered the workers to pry it open.

The workers began to try to pry open the metal door with their shovels, and with all their strength, a cry echoed in the woodland, which was easily distorted:

"Uh......"

"Ah......h

"Uh-huh!"

The tanned workers were all flushed with suffocation, and their muscles were bruised, but no matter how hard they tried, the door showed no sign of opening.

"No."

Realizing that the workers alone would not be able to open the ruins, the Master Engineer was about to look for other possible entrances, but was distracted by a pile of debris at his feet.

In the dirt dug up by the workers, a human hand that had long been turned into white bones was revealed, and the master engineer bent down and pulled the hand out of the dirt, only to hear a click, and the already fragile bone broke directly.

"What the hell is this...... What is it? ”

Looking at the metal strap on the white bone's wrist and a small disc-shaped object, the master engineer frowned, took the thing off the bone, wiped off the dust, and examined it carefully.

Underneath the round glass is a disc lined with thin lines and three hands of different sizes, each pointing to a different position.

"Hmmm......"

Staring at something he had never seen before, the master engineer fell into deep thought.

- Rumors of various advanced technologies hidden in the ancient ruins, he had also heard of them. While the old lord was still alive, the master engineer once led the workers to dig up some underground ruins.

However, all the ancient props found in the ruins were beyond his comprehension. What was found this time was no exception.

- Is it used to indicate directions?

Looking at the "disc" on his wrist in his hand, the master engineer was puzzled. It can only be put in his pocket for the time being, and continue to give orders to the workers:

"Open these dirt before dark, there are ancient relics inside, remember to move lightly, don't break it directly."

"Yes!" The workers nodded immediately.

As the workers began to rest, the master engineer sat down on a fairly flat rock next to him, looking up at the sky through the gap between the trees.

Judging by the position of the sun, it should be almost noon, and there should be some time before it gets dark.

Flamewind City's tool for measuring time is a round stone slab with a wooden stick in the center, and several scales are drawn on the stone slab, and the approximate time can be calculated by placing the stone slab in the sunlight and the position of the wooden stick's shadow.

- But when it comes to measuring time......

The master engineer, who had just put away the "metal disc", suddenly thought of something, and jerked out the ancient relic from his pocket, staring at the thin line with the scale on the disc, and the three hands.

"Is this ...... Used to measure time? ”

Thinking of this, the engineering master's eyes, which had been slightly narrowed, suddenly widened, and his right hand, which was still holding the disc, began to tremble slightly.

This equipment of unknown purpose does look a bit like a current time-measuring tool, and it is not a simplified version, but a completely enhanced version.

Noticing that the hands were mounted above the disc and connected to a small metal shaft underneath, the master engineer immediately realized that these hands should have been movable.

"Time is measured by movement...... I see......"

Realizing that he seemed to have figured out the essence of this thing, the engineer's serious expression finally unfolded, and a smile appeared on his face with excitement:

He had never been able to analyze the use of ancient relics, but at this time, he suddenly opened his mind, and it seemed that he had begun to approach the origin of this device!

The length of each day is varied, but there is a pattern to follow – the days become longer when it's hot, and the nights longer when it's cold.

The device may measure time by quantifying the time of day by turning a hand that maintains the same frequency all the time.

If that's the case, the scale on the disc should be an indicator to quantify time!

"One, two, three......"

The master engineer quickly counted the twelve large scales on the disc, and the smaller of each of them. He stared intently at the dial, and the smile on his face became more and more "rampant".

"Hah...... Hahaha...... Hahaha! ”

It was the first time I heard this person laugh so frantically, and the workers who were nibbling potatoes not far away all looked at me in surprise.

The master engineer held the round metal object in his hand, and the smile on his face was comparable to that of the scorching sun, and the whole person seemed to be burning, and turned and rushed towards the horse parked outside the dense forest.

"Where are you going?" A worker asked aloud.

"I'll go back to the lord." The master engineer laughed and replied, "I'm going to ask him to invest more in us, because this discovery is absolutely unprecedented for him!" ”

"What the hell is that?" Another bearded worker next to him stared suspiciously at the still glittering metal object in the master craftsman's hand.

"Hahaha, you say this?"

The master craftsman looked down at the disc he was holding in his hand, his voice suddenly became a little quieter, and he paused mysteriously for a while, and finally slowly spoke:

"You may be scared to say it, I have discovered an ancient 'time machine'!"
