Chapter 725 Diving into the Sand Sea
The battle continued until this point, and the situation became clear.

As long as the mechanical cornerstone, the MT, can hold it, everything will be easy, and victory is only a matter of time!

With the mechanical corner stone top acting as a shield in front, providing pincer attack, Gao Fei and Jiang Feng were able to calmly shoot and snipe the sandworm, creating a sneak attack effect.

Both mastered "close range fire" and "rapid fire".

Fire three shots in a row, plus three sneak attacks. As long as two shots hit, a sandworm can be shot stably.

The crisp sound of gunfire, the mournful cry of sandworms, the roar of magical engines, and the sound of metal and flesh colliding echoed across the desert.

Gao Fei, Jiang Feng, and Xiao Ma, who was driving the mechanical cornerstone, cooperated tacitly, and quickly killed all the remaining sandworms.

After the battle, the three of them took a short rest in the cabin to recover their stamina and magic power.

Ma Yun suddenly let out a snort, and forwarded a task reminder that she had just received to the team channel.

"Brother Fei! Sister Feng! The follow-up mission has been revealed, let's find the entrance to the underground ruins around here!"

"Where is the entrance?"

Jiang Feng stood up and looked out through the crystal window.

"is it this one?"

Goofy points to the minimap on the screen.

Right above the small map, a flickering blue spot appeared, which was very close to where the mechanical cornerstone was located, less than 100 meters away.

Jiang Feng and Ma Yun looked in the direction marked on the small map.

Just now, in the bunker blasted by Ma Yun's "fireball technique", reflective objects can be seen faintly.

Turn on the astrolabe, zoom in and take a closer look, and there is a broken spire exposed on the ground.

On the top of the tower stands a rooster made of brass, making a gesture of raising its head and crowing.

When a gust of wind blows, the brass rooster on the top of the tower will spin around with the direction of the wind, and the cavity in its body will whine.

"That's a weather vane." Goofy pointed to the brass rooster and said, "It's a common decoration on the top of medieval churches."

"So, there is a church buried under the yellow sand, and the spire of the sand pit is the bell tower of the church?" Jiang Feng asked.

"It may also be a palace." Gao Fei replied softly.

"Whether it's a church or a palace, the scale of the ancient buildings buried under the sand must be huge, and there should be a lot of ancient relics inside!"

Ma Yun imagined excitedly, and couldn't wait to activate the mechanical cornerstone to dig down the ancient ruins along the bunker.

The mechanical cornerstone was facing downwards, and the drill bit was humming and spinning, drilling toward the depths of the bunker, and a large amount of yellow sand was thrown out like golden water splashes.

Half an hour later.

The mechanical cornerstone has been drilled to a depth of about 50 meters underground.

With the help of astrolabe investigation, everyone was surprised to find that this mysterious building buried deep in the ground turned out to be a tall tower.

The position of the mechanical cornerstone is at the waist of the tower. Counting the attic, there are seven floors above the waist of the tower, each about seven meters high, and the interior has already been filled with yellow sand pouring in through the doors and windows.

Continue to dig down until the bottom of the tower, and it is estimated that there is still a height of about 40 to 50 meters.

From here, the geological structure changes significantly, and the soft sandy soil is replaced by hard rock formations.

The drill bit of the mechanical cornerstone collided with the rock and sparked, which was severely worn, and the progress of drilling also slowed down.

Seeing that the drill bit had become blunt, Ma Yun stopped digging quickly.

In the toolbox of the mechanical cornerstone, there is no spare drill bit to replace.

Ma Yun put on goggles and a breathing mask, and climbed out of the cabin carrying a compressed air bottle connected to the breathing mask with a tube.

The girl crawled hard in the sand until she reached the stopped drill bit, performed the "Complete Repair Technique" to restore the damaged drill bit as new, and then turned back on the original road.

It took more than half an hour to go back and forth.

Ma Yun went back to the cabin, shook her shoulders, and countless fine sands fell from her body and gathered into a pool under her feet.

"It's a good thing that Xiaoyun chose Artificer at the beginning, otherwise we would all be dumbfounded once the drill bit is scrapped." Jiang Feng took out a handkerchief and handed it to classmate Xiao Ma.

Ma Yun waved her hand to refuse, and took off the goggles and breathing mask, revealing her sweaty and red face.

She used a "magic trick" to remove the dust from her body, and her face was extremely solemn.

"Brother Fei! Sister Feng! I can't continue to drill down for now!"

"Why, hasn't the drill been repaired?" Jiang Feng asked in surprise.

"The bottom is full of rock formations, and the wear and tear on the drill bit is too severe. It needs to be repaired every ten minutes."

"It's not just troublesome, what's more terrible is that I don't have the ability to shuttle through the hard rock formation. Once the drill bit is damaged, I can't get close to it for repairs."

"From inside the cabin, can't the drill be repaired?" Goofy asked.

Ma Yun smiled wryly and shook her head.

"The drill bit is made of solid metal, and there is a spring filling structure between it and the engine room to provide cushioning and shock absorption. Repairing the damaged drill bit from the inside is beyond my ability to cast spells."

"Then what shall we do next?"

"There are two choices now." Ma Yun raised two fingers.

"First, let's take a long rest on the spot. I will use the rest time to modify the mechanical cornerstone and set up a convenient maintenance channel between the engine room and the drill bit."

"In addition, I have to re-prepare the spell list, memory 1 ring 'enchanted weapon', bless it on the drill, increase the enchantment level by 2, and temporarily strengthen the drill to +2 drill."

"For every +1 enchantment level, the hardness of the steel drill will increase by 2 points, and the total hardness will be +4, making it easier to dig rock formations."

"With my current mana, each enchantment lasts up to 70 minutes."

"That is to say, every 70 minutes, I have to drill into the maintenance channel, re-apply the 'enchanted weapon' to the drill bit, and cast spells to repair the damaged parts along the way."

"Wow! Is it so troublesome?" Jiang Feng held his forehead and smiled wryly, "Just hearing what you said, I already have a headache."

"There is another way to save trouble." Ma Yun continued, "We won't dig down anymore, we will get out of the mechanical cornerstone from here, pass through the window of the underground ruins, and enter the interior of the building."

She turned and pointed out the window.

Under the illumination of the magic light source, the windows of the tower came into everyone's eyes.

Most of the windows are broken and filled with yellow sand.

But in the direction of Ma Yun's finger, a window could be vaguely seen, and the crystal window was preserved intact.

Through the windows, the space inside the tower can be vaguely seen.

"The window on the opposite side is intact. It can be seen that from this floor, the interior of the building has not been completely filled with yellow sand. We can drill in and explore." Ma Yun continued.

"However, there is a small problem with this, that is, the window is too narrow, and the huge mechanical cornerstone cannot be drilled in. We can only leave it outside and explore the inside of the ruins on foot."
