Fifteen Waves
At this moment, Su Mu's instance world has reached the tenth wave.
But Su Mu didn't rush to have Little Drill Wind and White Bone Spirit Demon clear the monsters with all their might.
He stood high in the sky, overlooking the entire battlefield, his gaze always following the monsters pouring out of the cracks, observing their path.
The first nine waves of battles had led him to discover something extremely crucial.
These monsters are completely different from the monsters in wild lairs.
Monsters in wild lairs are intelligent; they will split their forces to encircle and flank, attack from behind, and prioritize attacking core cards.
But these monsters in the Gaokao Secret Realm have no intelligence.
Their goal was clear: the Stone Left Over from Mending Heaven atop Flower-Fruit Mountain.
However, they will not take shortcuts from all directions, will not cross mountains and valleys in a straight line, and will not adjust their routes according to the terrain. They will only pour out from the teleportation portal directly in front of them and advance towards the core card along a fixed route.
Moreover, they do not generate hatred.
This means that Su Mu can freely adjust the position of the dungeon tiles.
Su Mu's mind raced.
He can use the terrain to maximize the delay of the monster's advance.
With a sudden thought, he began to fine-tune the layout of the instance.
Move Flower-Fruit Mountain entirely to the rear, placing it directly behind Lion Camel Ridge.
Originally, the three mountains were side by side, with Flower-Fruit Mountain in the middle, Lion Camel Ridge on the right, and White Tiger Ridge on the left.
Now he has moved Flower-Fruit Mountain to the back of Lion Camel Ridge, so the two mountains are arranged in a front-to-back arrangement.
After the monsters emerge from the crack, if you want to get to Flower-Fruit Mountain, you must first pass through Lion Camel Ridge.
The Lion Camel Ridge extends for eighty kilometers.
Su Mu glanced at the panel.
Adjusting the dungeon sections requires Soul Power, but the amount is small; it's just moving the location of Flower Flower-Fruit Mountain, which costs five Soul Power.
I happened to have some left over.
After the adjustment was completed, the layout of the instance became a straight passageway.
Monsters poured out of the crack. In front of them was Lion Camel Ridge, behind which was Flower-Fruit Mountain Lion Camel Ridge, and behind Flower-Fruit Mountain was the Stone Left Over from Mending Heaven.
The eighty kilometers of depth of Lion Camel Ridge became an insurmountable barrier that the monster had to cross.
Su Mu glanced at the Stone Left Over from Mending Heaven: Grade A, with 580,000 HP.
At the summit of Flower-Fruit Mountain, Lion Camel Ridge and the White Bone Spirit serve as the first line of defense.
However, Flower-Fruit Mountain itself has no defensive buildings or trap cards, Stone Left Over from Mending Heaven are completely exposed.
He needs to adjust his strategy.
"Little Drill Wind, you guard the pass at the rear of Lion Camel Ridge."
Su Mu issued commands through the Soul Link: "White Bone Spirit, deploy defenses in the middle section of Lion Camel Ridge. Little Drill Wind guards the pass; if any monsters escape, you're responsible for clearing them out. White Bone Spirit, cover the middle section of the mountain path with a fire curtain to reduce the number of monsters as much as possible."
Without hesitation, Little Drill Wind flashed and transformed into a streak of dark blue light, rushing towards the rear of Lion Camel Ridge and stopping at the pass.
The White Bone Spirit stopped in the middle of the mountain path, swung her bone whip, and spread out a curtain of fire, burning the eleventh wave of thousands of goblins to ashes.
Eleventh wave, 1024 birds.
The White Bone Spirit was wiped out in three minutes and twenty seconds. With Little Drill Wind's interception at the later pass, they were all destroyed.
The twelfth wave, 2048 birds.
The White Bone Spirit took seven minutes and forty seconds. The area covered by the fire curtain was no longer enough, and the monsters began to circle around the edge of the fire curtain, surging towards the rear pass.
The Little Drill Wind charged back and forth through the pass, slaying any fish that managed to escape.
Su Mu glanced at the panel.
[Current wave: 12]
[Total kills: 4095]
[Integral coefficient: 1.2]
[Core Card Status: In Good Condition]
[Time: 14 minutes 30 seconds]
Starting from the tenth wave, the integral coefficient increases by 0.1 for each wave.
The eleventh wave is 1.1, and the twelfth wave is 1.2. This means that even if the kill efficiency decreases, the total score increases faster.
The thirteenth wave, 4,096 birds.
This time, the monster's level jumped to level seventeen.
Moreover, five elite overseers appeared, leading thousands of goblins to pour out of the crack, a dark mass that almost covered the open space in front of Lion Camel Ridge.
The White Bone Spirit's bone whip crackled and snapped, as waves of grayish-white flames spread out, burning swathes of goblins to ashes.
However, the goblins at level seventeen had a much denser skeleton than before. Although the damage from the gray-white flames was still considerable, it was no longer an instant kill. The goblins rolled and roared in the fire curtain, struggling to get up and continue charging forward.
A large number of monsters bypassed the White Bone Spirit's fiery curtain and ran towards the depths of Lion Camel Ridge.
They raced along the 80-kilometer mountain road, crossed the main peak, entered the valley behind, and then ran for another ten kilometers before finally seeing the outline of Flower-Fruit Mountain.
By the time they reached the foot of Flower-Fruit Mountain, they were already at their last gasp. Little Drill Wind returned from the pass and wiped them all out with a few slashes.
The thirteenth wave resulted in total annihilation.
Su Mu glanced at the panel.
[Current wave: 13]
[Total kills: 8191]
[Integral coefficient: 1.3]
[Core Card Status: In Good Condition]
[Time: 22 minutes 14 seconds]
The fourteenth wave, 8,192 birds.
The monster's level jumped to level 18.
This time, goblins were no longer just melee units; a large number of ranged archers and throwers appeared. They hid behind the melee monsters, and bone arrows and stones rained down. Although they did not cause any real damage to Little Drill Wind and White Bone Spirit Demon, the ranged monsters that slipped through the net began to hurl them towards Flower-Fruit Mountain.
However, the distance is too far.
Little Drill Wind flashed away from the pass, circled around to the flank, and pounced on the archers and throwers hiding behind. It was too fast; the level 18 ranged monsters didn't even have time to react before being slain one by one.
The White Bone Spirit continued to suppress the enemy from the front, unleashing a curtain of fire with her bone whip, burning the melee monsters in the front row to pieces. However, the fire curtain had a limited coverage area, and a large number of monsters bypassed it from both sides, rushing wildly along the mountain path towards Flower-Fruit Mountain.
The fourteenth wave consisted of over eight thousand level 18 monsters, and it took nearly twelve minutes to clear them all.
Su Mu glanced at the panel.
[Current wave: 14]
[Total kills: 16383]
[Integral coefficient: 1.4]
[Core Card Status: In Good Condition]
[Time: 34 minutes 28 seconds]
The fifteenth wave.
The crack suddenly widened, the dark green light turned dark red, and the monsters poured out several times faster than before. There were 16,384 goblins, level 19, mixed in with more than a dozen elite overlords and a goblin lord who was over five meters tall.
This is the first time the number of monsters has exceeded 10,000 since the start of the first level.
Little Drill Wind and White Bone Spirit rushed forward at the same time.
Little Drill Wind darted through the horde of monsters, its short sword flashing, each strike claiming a goblin's life. Its speed remained absurdly fast, but the sheer number of monsters was overwhelming; after killing one wave, more would follow.
The White Bone Spirit's bone whip lashed out so fast that its trajectory was almost invisible, and waves of grayish-white flames spread out one after another, but the coverage area of the fire curtain was limited, and monsters always managed to get around the edges.
Su Mu watched as the kill count on the panel rapidly increased.
A large number of monsters bypassed the defenses and rushed towards Flower-Fruit Mountain along the mountain path of Lion Camel Ridge.
But the 80-kilometer depth came into play... By the time these monsters reached the foot of Flower-Fruit Mountain, nearly an hour had passed.
During that hour, Little Drill Wind and White Bone Spirit had cleared out the monsters on the front of Lion Camel Ridge and returned to Flower Flower-Fruit Mountain to kill any that had escaped.
The fifteenth wave resulted in total annihilation.
