Chapter 1492: Water attack

"Just do what you said!" Joan took the scroll from Weiss and couldn't help feeling excited.
After Vis left, Joan immediately unrolled the scroll and laid it flat on the desk.
As Wisse said, the 6th ring of "earth movement" belongs to both the "natural divine art" and the "arcene". There is no encryption mark, and Joan can directly copy it into his spell book.
"Earth movement", similar to "plastic stone" and "ghost axe", is often used in construction engineering industries such as bridges, roads, and houses, so it is also generally called "engineering spell". Its common feature is that it can replace complex crafts. Or heavy labor, greatly save manpower and material resources, and speed up the efficiency of project construction.
Among all these engineering spells, the 6th ring of "earth movement" is one of them even if it is not the most powerful one!
The metamorphosis of this spell is that as long as you cast a spell, you can get a huge amount of earthwork!
How specific is it?
Performing a "earth movement" once can change the shape of the earth up to 750×750×20 cubic feet, that is 11.25 million cubic feet of earth!
The caster can decide how to deal with the soil at will, such as digging a trench tunnel, moving a small hill, and constructing or destroying a dam.
It is not difficult to know by simple calculation, as long as a "earth movement" can replace 1,000 engineering projects with hundreds of labors for hundreds of days!
If the spell of "plant growth" is worth an agricultural revolution, then the status of "earth movement" in the construction industry is equivalent to the status of "plant growth" in the agricultural field, reflecting magic on productivity from different sides. Great promotion.
With great excitement, Qiao An transcribed the 6th ring of "earth movement" into his spell book.
The following time, he and Weiss went to the upper reaches of the swamp under the rain, surveyed the environment along the Dring River on the spot, and chose a location that was most suitable for water storage and flood discharge.
In addition to the main stream of the Dring River, there are two smaller tributaries in the rivers that flow into the Everglades. Joan and Weiss chose to intercept one of the tributaries to build a dam, so as not to cause a downstream flow interruption and disturb the goblins in the valley.
At the same time, Joan did not neglect the investigation of the downstream goblin corps. When the sun went down, the three thousand goblin army entered the tortuous narrow valley as he expected.
Le Tu is still very alert, and sent a wolf rider to investigate first, paying special attention to the cliffs on both sides of the valley, lest there be ambushes on the mountain.
As for the Lizardmen Cavalry Battalion stationed on the edge of the swamp ahead, Letu knew it two days ago.
In the eyes of this goblin lord, if Weiss’s troops were killed halfway to intercept his regiment, it was pure suicide, and he did not mind using this opportunity to destroy this lizardman arm, it is best to capture Weiss. To lay the foundation for the future annexation of cold-blooded tribes and the expansion of their strength into swamp areas.
At the same time that Letu led his troops into the valley, far away on the bank of the river twenty miles away, Weiss unfolded the scroll in his hand and was performing "earth movement".
It takes at least ten minutes to perform the ritual to cast this six-ring spell.
During this period, Qiao An was not idle. He performed three "powerful phantoms" to hide the barrage dam that was rising from the ground, lest the enemy scouts that might fly through the air find the anomaly.
Ten minutes of tense atmosphere finally reached the last second.
The scroll in Weiss's hand ran out of magic and turned into ashes.
Wiping the rain off his forehead, Weiss turned and walked to Joan.
"Dr. Vader, it's time to control the water level."
Joan nodded and took out the "water control wand", all of the ten rounds of energy were excited in one breath, and the river rose sharply under the magical pull.
Joan spread his left palm and silently absorbed the energy of the "tears of gods", consumed 10 "powers of mythology", and recharged the "water wand" with energy.
Next, he lifted his wand expressionlessly, and it was the tenth burst of "controlling the water level"!
The rising river has flooded Joan and Weiss' ankles, and the two have to move to higher places.
"Dr. Vader, you have worked hard, let me see you next!"
Weiss rubbed his hands and began to cast spells.
Not long ago, the seven "control water levels" prepared by Weiss today were exhausted. The violently rising river was already on the verge of the dam, and the vertical height difference from the downstream channel was nearly 20 feet, forming a suspended reservoir, as if it might collapse at any time. From a distance, it was shocking.
"Mr. Vader, it's time to tear down the dam!"
Weiss glared his eyes, and his voice shivered slightly for the coming man-made natural disaster that was wicked away.
Joan glanced at the water level, shook his head expressionlessly, and handed a bundle of scrolls to Weiss.
"Uh, what is this?" Weiss took the scroll at a loss.
"Manipulate the water."
"Ah? The eight scrolls are all'controlling water bodies'?"
Weiss's eyes widened.
Joan nodded.
"Why did you get so many scrolls?"
"It was copied last night."
Weiss couldn't help but hissing, and suspected that Joan didn't sleep at all last night!
However, this cannot be explained. How can he restore his mana without taking a good rest?
The young Lizardfolk Patriarch shook his head with a wry smile, and had to give up the attempt to find reasonableness from this "monster" and unfold the scroll to focus on the spell.
With just two "controlling water bodies" scrolls, the accumulated flood water has already submerged the top of the dam, like a waterfall, pouring down the trapezoidal outer wall of the dam.
"Dr. Vader, this is enough." Weiss intends to return the remaining six scrolls to Joanne.
Joan waved his hand and told him in a calm, almost cold tone: "You take the rest of the scrolls. After the flood breaks through the embankment, continue to raise the water level with the Farfa, giving the downstream enemy troops a more lasting impact. One more minute can reduce the enemy's combat power, which is equivalent to helping the garrison in Delin Town reduce pressure."
So ruthless? !
Weiss couldn't help but sweat coldly, and secretly thanked Dr. Vader for his own side, if anyone was against him, it would have been mold for eight lifetimes!
Joan didn't say much, so he unfolded the "earth movement" scroll and calmly read the spelling mantra.
"Kemen!"
The ten-minute long spell-casting ceremony finally came to an end. When Joan chanted the last character that symbolizes the "earth", it seemed that a certain switch was activated. The magnificent barrage dam opposite it collapsed without warning!
With the roar of the sky, the entire dam fell apart, hundreds of thousands of square meters of mud mixed into the river of the embankment, forming a turbid torrent, like a black dragon with open teeth and dancing claws, roaring and rushing downstream!
Witnessing this terrible scene of landslides and cracks, Joan, Weiss, and the dragon cavalry of the cold-blooded tribe on the shore were all stunned.
