With Lu Wen's power, the electromagnetic cannon fired out at several times the speed of sound, its power comparable to an RPG rocket.
One shot blasted off the head of the Huo Undead Worm, but it did not actually die. It fell into a slumber due to its special body structure.
Before falling into a coma, the Huo Undead Worm remembered its mission and spit out the copper box inside its body.
Then its massive body softened and sank into the pool, giving it time to heal and regenerate.
"Bring the copper box over, and collect some of the Huo Undead Worm's flesh," Lu Wen ordered the Shadow Spirit Warriors.
The others finally recovered from Lu Wen's electromagnetic cannon attack, including Dōjima Yāyō and the other women.
Although the women knew about the electromagnetic cannon attack and had witnessed the power of Nanli Xiang's electromagnetic crossbow, they did not expect Lu Wen's attack to be so much more powerful.
While everyone was in awe, the Shadow Spirit Warriors brought the copper box to Lu Wen. They opened it, and inside were the three things Lu Wen had thought of before.
One perception, these three things all contained energy.
The Mountain Devil corpse was full of Yin Qi and killing intent, the natural jade womb contained pure spiritual energy, and the bronze toad emanated a strange energy.
"These are all items containing extraordinary energy. First, I'll store them away. After the King Xian Tomb is over, I will identify their ranks through the World Mark. Those I don't need can be sold or exchanged," Lu Wen thought to himself, waving his hand to store the three items in his personal space.
The Shadow Spirit Warriors also collected some of the Huo Undead Worm's body tissue. Lu Wen collected it and continued on his way.
On the side of Bottle Mountain, the Xie Ling martial arts experts and the soldiers under Lao Luo's command finally arrived after several days of travel.
After resting for a night, these people immediately got to work.
They split into two groups. One group climbed the cliff upwards to the Jin Dynasty tomb on the mountaintop, preparing to collect the various burial goods within the tomb.
Lu Wen's battle with this Corpse King ended quickly. He arranged ten or so axemen, and as soon as the coffin was opened, the unprepared Corpse King was slain.
The Corpse King died simply, without a fierce battle, so the burial goods in the tomb were not damaged.
The second group descended the cliff to the valley bottom and entered the underground palace through the tunnel Lu Wen had carved out.
The Xie Ling martial arts experts were numerous. Their goal was not only the various gold and silver jade, pottery and porcelain burial goods, but also the furniture and decorations within the underground palace, the roof tiles and wall bricks. They did not intend to leave anything behind.
In simple terms, they would take everything they could carry. They were truly scraping the bottom of the barrel.
A large number of Xie Ling martial arts experts and warlord soldiers gathered there, and they were overall strict on the outside but lax on the inside.
The outer perimeter was tightly guarded, and everyone had to undergo a thorough search when entering or leaving, but there were not many restrictions on movement within the palace.
The few transmigrators who had become entry-level Xie Ling martial arts experts had also managed to find out about the next steps in the plan through their own efforts.
But upon learning that Chen Yulou had already left Bottle Mountain, the Xie Ling martial arts experts and warlord soldiers split into two groups, planning to empty both the mountaintop tomb and the underground palace. The transmigrators who knew the plot were all dumbfounded.
They were the bottom rung of the Xie Ling martial arts experts and had no way to access information. Their information gathering was very inefficient.
Some transmigrators had been thinking about taking a gamble and deeply participating in the plot, hoping to earn more primordial coins in the settlement, but unexpectedly, the plot had changed drastically.
Was this the butterfly effect caused by their presence? Or was there some big shot who had already cleared the game?
The transmigrators all secretly guessed in their hearts.
But this had nothing to do with Lu Wen. He led everyone through a gourd-shaped cave, riding the flying centipede suspended in the air, and immediately saw the enormous building on the cliff face below.
The Heavenly Palace had a grand and imposing architectural style. Everyone else was drawn to it.
But Lu Wen only glanced at it before focusing his attention on the pool below the Heavenly Palace cliff. The real entrance to the King Xian Tomb was in the pool.
"Let's go. Let's go to the Heavenly Palace built by King Xian first and see if there's anything good left," Lu Wen said, controlling the flying centipede to approach the Heavenly Palace building.
Although in the original plot, the main group didn't get anything good in the Heavenly Palace building, Lu Wen now only took the original plot as a reference, no longer considering it the answer, so he decided to search it anyway.
He also sent out a few teams of Shadow Spirit Warriors, making them the advance force to explore the pool.
Lu Wen and his group arrived at the entrance to the building complex, and there was an archway inscribed with the words Lingyun Palace.
Stepping into Lingyun Palace, the architectural style had the essence of the Qin and Han dynasties.
Entering the Shangzhen Hall, a giant bronze cauldron was placed in the center of the hall. From afar, Lu Wen could sense the resentment and killing intent emanating from it.
"Good luck. This is another material for synthesizing and strengthening the Emperor's Banner," Lu Wen thought excitedly, stopping in his tracks.
He waved his hand, releasing several teams of Shadow Spirit Warriors and ordering them to clear the monsters in the palace.
Seeing Lu Wen's movements, the others, who had been drawn to the giant bronze cauldron, also cautiously observed the situation in the palace.
The light was rather dim. Lu Wen's women took out their flashlights and shone them around.
Hanging from the ceiling of the palace were a dozen or so humanoid objects. When the light shone on them, they seemed to be awakened and began to tremble.
These humanoid objects wore robes of various colors, but they were ragged and torn. Their faces were as twisted and grotesque as the pupae they had encountered before, and their bodies contained a lot of resentment and killing intent.
These ghosts were also creations of King Xian's Gu art, tasked with guarding this palace.
"King Xian's Gu art is cruel, but his methods are indeed extraordinary. The Gu art creations have not died after a thousand years," Lu Wen exclaimed.
But they were able to sleep for a thousand years and still survive. These Gu art creations needed a little time to wake up, but Lu Wen was ruthless. Upon discovering the change, he decisively released the Shadow Spirit Warriors.
These ghosts on the ceiling of the palace, like the previous Corpse King from Bottle Mountain, had not yet fully awakened from their slumber and were quickly dispatched by the Shadow Spirit Warriors, one by one.
Lu Wen used the Emperor's Banner as usual to capture and suppress the souls of these Gu art creations, thinking to himself, "These ghosts in the palace, were they priests under King Xian in their previous lives? I wonder if these souls will be stronger."
Keeping this guess in mind, Lu Wen planned to verify it later.
After dealing with the ghosts on the ceiling of the palace, Lu Wen spread out his perception to scan the area.
"There are no dangers in this palace now. You are free to move around," Lu Wen said.
百合子 swept her flashlight and reminded them, "There are murals on the walls of this palace."
Chen Yulou, Partridge Whistle, and Dōjima Yāyō, and the others were all very curious about everything in King Xian's tomb. They all stepped forward to examine the contents of the murals.
Lu Wen went up to the giant bronze cauldron, called out a team of Shadow Spirit Warriors to lift it, and sent it into his personal space to store it away.
Like the coffin artifact he had previously obtained, Lu Wen's current energy was insufficient to provide the synthesis consumption. He would synthesize it later when he was stronger.
