The fighting continued until this point, and the situation became clear.
As long as the MT, the mechanical corner stone, can hold it, everything will be easy, and victory is only a matter of time!
A mechanical corner stone stood in front as a shield, providing a flanking attack. Gao Fei and Jiang Feng were able to calmly shoot and snipe at the sandworms, creating a sneak attack effect.
Both mastered "Close Shot" and "Quick Shot".
Three consecutive shots in one round, plus three sneak attacks. As long as two shots hit, a sandworm can be stably killed.
The crisp sound of gunfire, the wail of sandworms, the roar of magic engines, and the sound of the collision of metal and flesh intertwined and echoed over the desert.
Gao Fei, Jiang Feng and Xiao Ma, who was driving the mechanical corner stone, cooperated tacitly and quickly killed all the remaining sandworms.
After the battle, the three of them took a short rest in the cabin to restore their physical strength and magic power.
Ma Yun suddenly let out a sigh and forwarded a task prompt she had just received to the team channel.
"Brother Fei! Sister Feng! The follow-up mission has been released. Let's find the entrance to the underground ruins nearby!"
"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.
Directly above the mini-map, a flashing blue spot appeared, very close to the location of the mechanical corner stone, less than 100 meters away.
Jiang Feng and Ma Yun looked over according to the direction marked on the small map.
In the sand pit exploded by Ma Yun's "Fireball Technique" just now, reflective objects were vaguely visible.
Turn on the astrolabe, zoom in and take a closer look. What is exposed on the ground is a broken spire.
On the top of the tower stands a rooster made of brass, raising its head and crowing.
When a strong wind blows over, the brass rooster on the top of the tower will rotate in accordance 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, "a common decoration on the top of medieval churches."
"So, there is a church buried under the yellow sand, and the spire exposed in the sand pit is the bell tower of the church?" Jiang Feng asked.
"It might also be a palace." Gao Fei replied softly.
"Whether it's a church or a palace, the ancient building buried under the sand must be huge in scale, and it should contain many ancient cultural relics!"
Ma Yun thought excitedly and couldn't wait to start the mechanical corner stone and excavate this ancient ruins along the sand pit.
The mechanical corner stone is pointed downwards, the drill bit is buzzing and rotating, drilling deep into the sand pit, and a large amount of yellow sand is thrown out, like golden water splashes.
Half an hour later.
The mechanical hornstone 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 underground turned out to be a tall tower.
The mechanical corner stone is located at the waist of the tower. Including the attic, there are seven floors above the waist of the tower, each floor is about seven meters high. The interior has long been filled with yellow sand pouring in through the doors and windows.
Continue digging down until you reach the bottom of the tower, which is estimated to be about 40 to 50 meters high.
From here on, the geological structure changes significantly, with soft sandy soil being replaced by hard rock formations.
The drill bit of the mechanical angle stone collided with the rock and caused sparks. It was severely worn and the drilling progress also slowed down.
Ma Yun saw that the drill bit had become dull and quickly stopped digging.
There are no spare drill bits in the tool box of the mechanical corner stone.
Ma Yun put on goggles and a breathing mask, carried a compressed air bottle connected to the breathing mask with a tube, and climbed out of the cabin.
The girl crawled hard in the sand until she reached the stopped drill bit, used the "complete repair technique" to repair the damaged drill bit like new, and then turned back along the original path.
It took more than half an hour to go back and forth.
Ma Yun got back into the cabin and shook her shoulders. Countless fine sand fell from her body and gathered into a puddle at her feet.
"Fortunately, Xiaoyun chose the magician in the first place, otherwise we would all be dumbfounded once the drill bit was scrapped." Jiang Feng took out his handkerchief and handed it to classmate Xiao Ma.
Ma Yun waved her hand to refuse and took off her goggles and breathing mask, revealing her sweaty and red face.
She casually used a "magic trick" to remove the sand and dust from her body, her face looking particularly solemn.
"Brother Fei! Sister Feng! We can't continue drilling for the time being!"
"Why, isn't the drill bit already repaired?" Jiang Feng asked in surprise.
"The bottom is full of rock formations, which wears out the drill bit so much that it has to be repaired every ten minutes or so."
"It's not only troublesome, but what's more terrible is that I don't have the ability to shuttle through the hard rock formations. Once the drill bit is damaged, I won't be able to get close to repair it."
"Can't the drill be repaired from inside the cabin?" Gao Fei asked.
Ma Yun smiled bitterly and shook her head.
"The drill bit is made of solid metal, and there is a spring-filled structure that provides cushioning and shock absorption between the drill bit and the cabin. Repairing the damaged drill bit from the inside is beyond my ability to cast spells."
"Then what should we do next?"
"Now there are two choices." Ma Yun raised two fingers.
"First, we will take a long rest on the spot. I will use the rest time to modify the mechanical corner stone and set up a convenient maintenance channel between the engine room and the drill bit."
"In addition, I have to prepare a new spell list, memorize the 1st level of 'Demonized Arms', add it to the drill, increase the enchantment level by 2, and temporarily strengthen the drill to 2 drills."
"For each enchantment level, the steel drill's hardness increases by an additional 2 points, with a total hardness of 4, making it easier to dig into rock formations."
"With my current mana, each enchantment can last up to 7 minutes."
"That is to say, every 7 minutes, I have to get into the maintenance channel, re-apply the 'demon weapon' to the drill bit, and cast spells to repair the damage."
"Wow! Is it so troublesome?" Jiang Feng held his forehead and smiled bitterly, "Just hearing you say that, I already started to have a headache."
"There is a more trouble-free way." Ma Yun continued, "We no longer dig down, we will break away from the mechanical corner stone from here, go 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 tower's windows came into view.
Most of the windows are broken and filled with yellow sand.
But in the direction of Ma Yun's finger, a window was vaguely visible, and the crystal window was actually preserved intact.
Through the windows, the space inside the tower can be vaguely seen.
"The window opposite is intact. It can be seen that starting from this floor, the inside of the building has not been completely filled with yellow sand. We can get 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 corner stone cannot be drilled in. We can only leave it outside and explore the interior of the ruins on foot."
