As the coughing sound came again, they wanted to understand that it was not the voice of the soldiers, so they were a little relieved and put away the fighting formation.

Yue Guanchao looked at these dead soldiers, they were undoubtedly the escorts of Yin Zun, but why did they make them such a terrorist organ, he really didn't know what he meant.

"Engong, these soldiers are all urged by the agency behind them, which one is the lifeline of the agency?"

For this, Yue Guanchao had no way of knowing, he only saw that behind the corpses of the puppet soldiers were square prismatic copper pillars up to the top of the corridor, which were uneven and uneven, covered with various gear copper strips, round hole iron shafts, and machine spring keys, and countless telescopic and rotating machines buzzing and rotating among the copper pillars, seemingly never tired!

"Let's go, let's go to the city gate tower and have a look!"

Yue Guanchao lay on the battlement, and gestured to Song Siyuan opposite, signaling the two of them to go to the city gatehouse.

Waiting for Song Siyuan and Mao Ye to agree, they walked through the corridor and came to the towering city tower in front of the plaque in Shangjing.

This tower is one size smaller than the Urn City Gate, it is narrow and low to the naked eye, and the roof of the hall used is also lower than the top of the Heavy Eaves Mountain, just an ordinary gray tile summit.

Look carefully, the walls of the palace are painted with red color, decorated with gold-patterned pillars, and the cornices, owls, panes, and double arches all have ancient beast totems outlined by colored paint, and it looks as if there are hundreds of fierce beasts floating on the outside, and the evil spirit is wanton.

Pushing open the palace door, the situation in their eyes made the two of them gasp, and the thick smell of clear oil in their noses never lingered.

The exterior of the capital city tower is gorgeous, but the inside is not dressed up, and they imagine that the picture decoration is completely different, everywhere you can see half-height copper beasts, copper standing soldiers, copper kneeling women, the top of the hall has countless strange scriptures swaying and trembling, in the gray candle fire on the outside, the shadow is enough, if the ghost lingers!

Yue Guanchao browsed left and right, and roughly estimated that the internal space of this palace was the size of five or six private houses, and in the middle was the brass platform.

The platform in front of him is as thick as an alchemy furnace, cast from brass, and the pedal stone slab is on the top of the temple, wide up and down, and the waist and abdomen are narrowed.

At the top are eight golden-bodied macaques with their butts facing upwards and their claws outstretched, and their posture is completely modeled after the design of the macaque, which is vivid and distinctly hairy, and the two arms are the copper arm springs of the mechanism.

And the copper fence at the bottom is not empty, kneeling and crawling the basin-sized golden toad!

The toad's hind legs are nested and the front paws are propped up, and the belly is swollen like a ball as if it is angry, biting the copper ball and lying on the lotus copper platform, it looks fat and bulky, but the waist and back are inlaid with more than 1,000 gold coins, as if the body is full of pimples, bumps and bumps!

Once the water washes over the gear behind the buttocks, the golden monkey will raise its arms as if it is alive, and then the water spewing out of the golden cicada's giant mouth will be linked up and down, which will drive the movement of the mechanism, and the rocker arm of the 10 million copper shaft will be dislocated and reciprocated, transferring the water wheel capacity to the bottom of the waterhole.

Yue Guanchao had never seen such a sophisticated instrument, approached the waterhole and looked down carefully, the bottom was about five steps wider than the copper platform, and the water inside was only more than half a waist high, not too deep, there were no living creatures, only thousands of copper spring gears full of crunching sounds.

The rotational force generated by these gears continues to be transmitted outward, driving thousands of auxiliary copper pillars to run precisely!

Judging from the buzzing and shaking under their feet, the floor under their feet is probably full of gears, and if so, it would explain why the Centipede Star Hammer can operate, as long as the main mechanism is not damaged, they will be like this for thousands of years!

"Engong, if it's turned with gears, why don't these things rust?"

Ma Chang was about to open the fire fold, Yue Guanchao quickly stopped him from picking up the dagger and stabbing it into the pool, and took it to the tip of his nose to smell it, this smell was very familiar to him:

"This pool is not water, it is tung oil that can maintain gold, I feel that our feet are all tung oil, otherwise the palace will not smell so big, don't use fire folds, so as not to ignite the oil and gas here."

The two of them looked at the mechanism with a flashlight, and the whole mechanism used the flow of tung oil to urge the copper shaft gear, and the gas produced after the evaporation of oil and gas lingered in the temple, which was equivalent to indirectly delaying the corrosion of the copper utensils, and the brass utensils here were brighter than the outside, presumably for this reason.

"If this is a mechanism, where is the lifeline?"

Yue Guanchao carefully observed the mechanism in front of him, when it was manufactured, he had already considered that there was tung oil to operate, except for the bare gears, all the parts were sealed in the copper platform, tung oil is both protection and lubricant for the parts, he looked around, but he couldn't find any flaws.

"Could it be that this mechanism can't be stopped, what kind of ingenuity is this, it's so strange."

Ma Chang carefully touched the copper fence of the waterhole, and neither of them could find the direction clearly, let alone the situation.

"I can't find it for a while, and I can't help it, I feel that as long as the tung oil is gone, this mechanism will naturally stop, but so much tung oil, how to get it out."

Yue Guanchao was puzzled, so he had to withdraw from the temple first and stand in front of the city gate tower, shouting downward:

"Master Cat, we found the mechanism, but there is no gap or anything on it, and it is not easy to break the mechanism."

"Yue Xiaoyou, you describe it to the old man, I'll hear what kind of pin it is, and I can discuss countermeasures with Song Qianjin!"
