"August 12, 899, Xinghai calendar."

"This mission is to enter the deep underground of skeletal Dragon Star, so spark is carrying out large-scale modification in the maintenance base on the orbit circle of hazy God star, adding a large number of underground stealth modules, as well as a strengthened shell resistant to high temperature and high pressure."

"I'm annoyed that the spark's main gun, Tianlong Chuanxing gun, is going to be transformed into a super large light energy rock crusher. To put it bluntly, it's a large drill made of dark light!"

"The spark will go deep into the earth with the help of the Xuanguang drill modified by the main gun!"

"Spark is the most advanced multi-function assault ship in the imperial army. It is often refitted. In the past, many warships of the same level were refitted in a mess. I used to laugh at my comrades on those warships. I didn't expect that it was my turn today."

"I used to be the most powerful gunner in the past. I used to control the Tianlong star piercing cannons to attack with all my strength. Even the demon emperor has a chance to kill him with one shot!"

"But today, I have to learn how to operate the Xuanguang drill bit and squirm under the ground like an earthworm. If I had known that, I might as well have stayed in the magic moon star field to suppress bandits."

"August 15, 899, Xinghai calendar."

"This task is very urgent. Just after the refitting, we can't wait to jump into the sky and appear in the gravitational circle of skeletal Dragon Star."

"The great expedition took away the best refiners of the Empire, and left behind were a group of three legged cats. They refitted the spark into a pile of garbage. They only added several underground stealth modules, but they collided with the star jump system."

"A lot of people on the ship were affected by the sequelae of broken void, vomiting and diarrhea. In serious cases, they were possessed."

"Fortunately," tetanus "is a common disease on the battlefield. We stayed in the orbit for half a day and recovered our combat capability."

"According to intelligence, the planet in front of us is most likely one of the caves of the skeleton dragon demon, the most powerful demon of the demon clan, 30000 years ago at the beginning of the great dark age."

"It seems that the desperate remnant of the demon clan wants to dig out a lot of secrets from the powerful demon clan 30000 years ago."

"How can we please them?"

"August 16, 899, Xinghai calendar."

"We encountered an unprecedented big wave on the Dragon planet. In the depth of the sea, there is a kind of terrifying spirit beast which is as long as 1000 meters and has never been seen before. They seem to be a mixture of armored monster and soft monster, and even the huge tentacles grow strong armor."

"Our main gun has been refitted into a Xuanguang drill bit. It has no long-range attack ability at all. The rest of the auxiliary guns are used to tickle the spirit beast."

"The tide outside is too fierce. We are limited in manpower. The captain is not willing to release crystal armor to fight easily. In case several Armor Division are damaged, it will be greatly detrimental to the later action."

"At the last moment, I thought of a way. The captain manipulated the spark to collide with the bastard. At the moment of the collision, I started the Xuanguang drill bit and drilled a huge hole with a diameter of more than 50 meters on the bastard. Then I used the auxiliary gun to directly attack the bastard's internal organs and kill him alive!"

"Ha, I didn't expect that after refitting it into a drill bit, the Tianlong star piercing gun is still as powerful and refreshing as ever!"

"We cut the body tissues of some giant sea animals and come back for analysis. Its cell structure and the circuit of demons circulating in cells are very different from the demons now, but some of them are like the ancient demons 30000 years ago."

"According to our analysis, it is very likely that this is a kind of monster that the skeleton dragon demon brought to this planet 30000 years ago. After the skeleton dragon demon clan perished, its intelligence gradually degenerated and it became a spirit beast with no wisdom but survival instinct."

"In this way, the possibility of the existence of dragon devil cave on this planet has greatly increased."

"August 17, 899, Xinghai calendar."

"We found a huge relic. Countless Qi Tian pillars bound a huge monster skeleton. It should be an ancient forbidden system. Maybe it was used by dragon demons to torture enemies and traitors."

"Not far from the ruins, there is a great rift valley that reaches 10000 meters underground. In order to save power, we first drove the spark deep underground and built a temporary landing site on the cliff. Then we drilled to the center of the earth at a slightly inclined angle."

"The surface of skeletal Dragon Star is desolate and barren, but the underground world is incredibly rich. Most of the spiritual veins of this planet are semi liquid, forming underground rivers of spiritual fluid and oceans of spiritual power, where countless exotic animals and natural resources and treasures multiply."

"In the afternoon, we encountered the small-scale harassment of the demon clan. After a short fight, we caught a prisoner."

"The war has been going on for hundreds of years, and now the demon clan has already lost the arrogance and hegemony of the heyday of the demon empire. It didn't take much effort to pry open his mouth and extract a lot of information."

"Our analysis is correct. This is a group of fish who have escaped from the encirclement and suppression of the moon magic star. They accidentally found the cave on the skeleton Dragon Star, because all the star fields around are surrounded by us and there is no place to escape. They just put all their eggs in one basket and want to look for a ray of life here."

"August 18, 899, Xinghai calendar."

"This demon remnant is just the end of a strong crossbow. Soon we completely defeated him. Even the last demon warship was sunk."

"We have also discovered an underground world of unprecedented scale, as well as an underground ocean with infinite powers!"

"The scale of this underground world is so huge that it completely exceeds the bearing limit of geological structure. It should be supported by some ancient secret method."

"The world of cultivating truth is really wonderful. In ancient times, we don't know how many secret skills and supernatural powers are hidden, waiting for us to explore."

"I kind of like the feeling of operating a huge bit and drilling underground."

"The lair of the skeleton dragon devil is deep in the earth sea. Here lies an antique town. The huge conical building in the middle should be where the cave is."

"We sailed to it, ready for the most thorough study."

"August 19, 899, Xinghai calendar."

"We are so wrong! This is a trap! It's an irrefutable trap

"August 23, 899, Xinghai calendar."

"We're done."

"The overall damage degree of spark reached 83%, most of the core structures were scrapped in the fierce battle, basically leaving only one empty shell."

"The damage degree of the main control crystal brain reached 95%; The damage degree of star jump system reaches 91%; The damage degree of superstar communication system reaches 93%; Twenty two of the 24 main power runes burst out, and we were stranded on a sea bed and completely trapped in the depths of the Dragon Star. "

"Don't talk about breaking up the void, jumping in the sky, or even sending signals to the nearest base."

"Seventy percent of the crew died, including me. The survivors were seriously injured and were unable to leave the warship."

"The three Yuanying friars, the captain, the first mate and the stargazer all fell."

"Even if we managed to repair the control system, we would not be able to operate the spark flexibly without three to six months of training."

"The crystal brain is seriously damaged, and we have lost the stargazer, so we can't accurately detect the star torch."

"Even if we fix the star jump system, if we barely jump, who knows where we will be sent."

"However, if it wasn't for the sacrifice of the three yuan infant friars, we would have died long ago without a place to bury ourselves, even to a more terrible end."

"Among the survivors, my accomplishments and rank are the highest. According to the Imperial Army regulations, I am the temporary captain."

"Fortunately, we agreed with the base that we would send a contact signal every five days. If we didn't receive the signal twice or three times, the base should send new crystal warships to search us."

"This idea made me feel a little more stable. I sent more people to repair the spark and thought about what happened to us at the same time."

"There is no doubt that the so-called cave on the skeletal Dragon Star is a complete trap. This is not a cave at all, but the tomb of the skeletal dragon demon!"

"No, it should be said that it's the place of dormancy, the old nest that has been dormant for tens of thousands of years, waiting to wake up!"

"With all the information and everything we've been through, I guess that's how it went."

"Thirty thousand years ago, at the end of the great dark age, more than a dozen of the most powerful demons fought for the title of demon emperor in order to unify the star sea. The skeleton dragon demon family is one of the losers. The skeleton dragon demon is very likely to be seriously injured and on the verge of death."

"He didn't want to die like this. He used secret arts to make himself in a state of suspended animation. Relying on this land sea with abundant spirit, he slowly healed for tens of thousands of years."

"It is also possible that the life form of skeletal dragon demons is different from that of ordinary demons. They can exist for tens of thousands of years in the form of demon spirits in a special way."

"After all, it was tens of thousands of years ago. We lack a lot of information and don't know the details of the skeleton dragon demon."

"It wasn't until 30000 years later that the skeleton dragon devil finally woke up, but for some reason, he was trapped in the depths of the earth sea and couldn't escape."

"Or maybe he needs some intelligent life to come back to the sea of stars through the way of giving up!"

"Soul snatching is very popular in the world of ancient cultivation. Since the skeleton dragon demon was the most powerful man in that era, he was also proficient in this poisonous secret method."

"In a word, he is trapped in the ground and can't rely on his own strength to escape from the inside. He can only break the ban with the help of external forces."

"And that demon remnant soldier, as well as US stupid idiots, are all lured here by it!"

"Although the remnant soldiers of the demon clan were eliminated in time, we broke the ban and released the skeleton dragon demon in ignorance!"
