The original repairer

Chapter 132 Design to Enter the Underground Palace

Passing through the South City Gate, Shi Chen stepped into the Nanhai Fairy City.

Looking up, the houses in the fairy city were completely destroyed and in ruins. Debris was everywhere, black bloodstains could be seen everywhere, and the bumpy and uneven roads of the fairy city made this Nanhai Fairy City look like it had been hit by a terrible earthquake.

There weren't many sea monsters in the Immortal City, and those that were seen were mostly at the Foundation Establishment stage or above. The Immortal City's main formation had been destroyed, and all the restrictive formations had ceased to function.

Shi Chen's spiritual sense quickly swept across the entire fairy city, except for the City Lord's Mansion, which he did not dare to use his spiritual sense to explore rashly.

Four Nascent Soul sea sirens were stationed near the city gate, and eight more were stationed near the City Lord's Mansion. Within the entire Immortal City, which covered an area of over thirty miles, there were twenty-three Golden Core sea sirens scattered about, and three hundred and eighty-six Foundation Establishment sea sirens within the city.

Shi Chen came to the vicinity of the city lord's mansion, found a house without a siren, and took it for himself.

The spiritual vein of the fairy city is located underground in the city lord's mansion, sealed in the underground palace by a formation, serving as the spiritual source for the operation of the fairy city's formation.

The City Lord's Mansion is located above the spiritual vein. Apart from the underground palace of the spiritual vein, this is the place with the richest spiritual energy in the entire fairy city.

Now the Immortal City has fallen into the hands of the Sirens. The defensive formation of the Immortal City has been destroyed, and the underground palace that seals the spiritual veins is guarded by another formation. The Sirens cannot enter for the time being.

The Siren clan has few formation masters, and their attainments in formation are even worse.

The entire fairy city is under the rule of sirens, but they don’t even send a team of sirens to guard the entrance to the underground palace. Are they too careless, or do they really not care about this spiritual vein?

Shi Chen was thinking about finding a way to enter the City Lord's Mansion, approach the entrance to the underground palace, break the fourth-level formation, and then enter the underground palace to extract the spiritual vein.

The difficulty lies in how to reach the entrance of the underground palace without being discovered in the process.

There are two teams of foundation-building sea monsters guarding the gate of the City Lord's Mansion. After entering the gate, you have to go through the front hall and the main hall.

The entrance to the underground palace is in a rockery cave in the backyard. Outside the cave is a lake and pavilions. There are also many sirens playing in the lake.

If the God Forbidden Array could be activated, with the current security of the City Lord's Mansion, Shi Chen could sneak in at any time without being noticed. However, the Immortal City Array was damaged, and there were sea monsters scanning everywhere. Once he appeared outside, it would be easy for the sea monsters to discover his whereabouts.

It might not be a big deal outside the City Lord's Mansion, but if the Siren finds out that you have entered the City Lord's Mansion without permission, it will be very dangerous.

After three days of careful observation, it was found that there were very few sirens entering and leaving the City Lord's Mansion. There were only about ten to twenty sirens entering and leaving every day, mainly to convey orders.

It is really difficult to sneak into the City Lord's Mansion, so we have to find another way.

The core of the Immortal City's defensive formation is located in the City Lord's Mansion. The formation base must be within the Immortal City, and the formation eye is generally not located in the City Lord's Mansion. As long as a formation base can be found, the formation eye can be traced back to the formation base through the connected formation patterns.

Shi Chen was confident that he could modify the fourth-order city defense formation of the South Sea Fairy City, move the spiritual source center to another place, and activate the forbidden god formation, so that he could sneak into the city lord's mansion.

So, Shi Chen wandered around the Immortal City, especially near the four city gates in the east, west, south and north, and used his spiritual sense to carefully explore the Immortal City formation.

In ten days, the thirty-six array bases of the city defense array were found, including the fourth-level God-forbidding Array, Sky-forbidding Array, Defense Array, Strangling Array, and Suppression Array.

Six of the array bases were damaged and the twelve array patterns were broken, so the entire complex array could not operate normally.

Shi Chen didn't have enough materials to completely repair the complex formation, but if he could only partially operate the complex formation for a while, it would still be possible.

It is still feasible to split the compound formation and repair one or two fourth-order formations. As long as it can run for a period of time, Shi Chen will be able to sneak into the City Lord's Mansion.

Before repairs could be made, an escape route had to be prepared. After setting up the formations at the four city gates, he went to the sirens' station outside the city and ordered them to march north along the city walls until they reached the west gate, then travel a hundred miles west to find a valley to wait.

After modifying the spiritual supply paths of the Forbidden God Array and the Forbidden Sky Array and repairing the array bases of the two arrays, Shi Chen's spiritual consciousness connected to the two arrays and he discovered that the activation of the Immortal City Array required an extremely large supply of spiritual energy.

According to the overall consumption of the entire formation, one top-grade spirit stone is needed per hour.

To repair the functions of the two formations, one hundred high-grade spirit stones are required every hour.

To activate the formation, using the spirit stones on your body as the spiritual source, you can only last for a quarter of an hour.

Therefore, immortal cities are usually built on spiritual veins, and they must be of the third grade or above.

The two formations were modified again, reducing their range to half, covering only half of the Immortal City. Originally encompassing a space three hundred feet high, it was reduced to a height of one hundred feet.

In the end, the two large formations consumed thirty high-grade spirit stones per hour, which was equivalent to three thousand medium-grade spirit stones, or three hundred thousand low-grade spirit stones.

The Immortal City Formation is simply a gold-devouring beast, no! It is a soul-devouring beast.

Shi Chen had 300,000 low-grade spirit stones on him. It was well worth spending hundreds of thousands of low-grade spirit stones to obtain a spirit vein.

Shi Chen took out two hundred thousand low-grade spirit stones and put them into the spirit source supply array of the large array. He calculated the time it would take for the array to run, but it still felt unstable, so he put in another one thousand medium-grade spirit stones.

The spiritual source is of vital importance to the formation.

The same formation, with different spiritual source qualities, will produce completely different effects.

Just like the current city defense formation, if there were high-quality spirit stones, he would also consider putting in ten.

The higher the level of spiritual source, the better it will be in terms of combat effectiveness.

If the sea monster stationed here discovered that there was something fishy about the formation, with the current quality of the spiritual source, he would be able to easily break the formation with just two or three attacks.

If thirty high-quality spirit stones were put in, it could at least withstand the attack of a cultivator in the Spirit Transformation Stage for a quarter of an hour.

In the Lingyuan formation circuit, Shi Chen set up a start-stop formation, put away the formation talisman, carefully covered up the traces, and then returned to the house next to the city lord's mansion.

After preparing the battle flags, Shi Chen began to act.

Activate the Immortal City Formation, ban gods and the air.

Click! Click!

Five breaths later, half of the Immortal City was in chaos. The sirens that had been flying above the Immortal City suddenly fell down, and half of the Immortal City was sealed off by the formation.

I quickly came to the place I had observed in advance. It was a dead end alley next to the City Lord's Mansion.

He leaped forward, easily crossing the three-meter-high protective wall and entering the city lord's mansion.

According to the plan, we followed a route where no sirens walked and quickly arrived at the edge of the rockery.

He raised the refined formation flags and set up an illusion formation and a forbidden god formation within a radius of five meters at the entrance of the rockery.

Only after entering the formation can the fairy city formation be closed.

In less than a moment, half of the immortal city's forbidden god and forbidden sky formations stopped functioning again.

The sea monster cultivating in the main hall of the City Lord's Mansion suddenly opened its eyes when the God Forbidden and Sky Forbidden formations were activated. However, it only sensed the two formations in surprise. Seeing that only the God Forbidden and Sky Forbidden formations were not affected, it did not pay much attention to them.

After Shi Chen entered the rockery, set up the formation, and stopped the fairy city formation, the sea monster opened its eyes in surprise again, and scanned the fairy city with its spiritual sense once, twice, and three times.

The entire fairy city was clearly visible under the spiritual sense of the sea monster. He did not find anything special, but his spiritual sense still could not scan the entrance of the underground palace.
