While Dark was mentally sensing the surrounding environment, Guo Teng was recording the information provided to him by Leah.

[Master, the current maximum range of the magic crystal cannon is about 1576 meters, the explosion radius is 1.5 meters, the killing radius is 3 meters, and the impact radius is 6 meters.]

[The speed of the cannonball is about 431 meters/second, and the fall time of the cannonball is between 3.65 and 4.02 seconds.]

[The drop angle is between 34° and 58°.]

[The firing speed of the magic crystal cannon is 15~17 seconds/shot.]

[Rough statistics, there are currently about 536~578 magic crystal cannons on the wall of Buris.]

The three skeletons went about their own business, and Guo Teng listened to the information about the magic crystal cannon that Leah provided him.

It seems simple for Leah to provide information about the magic crystal cannon, but it is actually very life-saving for Guo Teng.

He knew that the magic crystal cannon's range covered the second front.

There is basically no safe place in the entire second front.

The magic crystal cannon on the wall of Buris City is coming. The capable people cast spells to protect themselves, and the rich people equip themselves to protect themselves.

Guo Teng is a necromancer apprentice who has just traveled through time. He has no ability and no money. How can he protect himself?

The answer is to dig trenches.

After knowing the angle of the bomb's fall, Guo Teng directed the skeleton soldiers to dig the trench at a slope angle.

Dig out the excavated soil and add it to one side to make it higher, and dig out a slightly lower and flat surface on the other side.

When the cannonballs on the wall of Bresse hit, Guo Teng burrowed into the trench.

Unless Guo Teng points his back, a magic crystal cannon on the wall of Buris sent him a shell with an angle of more than 60°, which just hit the trench, allowing Guo Teng to remake.

Otherwise, the current method is a simple and easy life-saving method for Guo Teng.

In fact, Guo Teng only had to dig a trench.

When enemy fire came, he hid in a pit.

But now that Captain Dark forced him to join the 19th Mage Regiment, Guo Teng naturally had to consider other mages and form a good relationship.

No matter whether people use it or not, it is always a thought.

Guo Teng commanded the skeleton soldiers to dig trenches, and the skeleton soldiers to dig the magic circle.

Dark, who did not sense any abnormality mentally, also opened his eyes at this time.

He did not find the reason why the recovery speed of mental power and magic power was accelerated.

Nonsense, without Guo Teng telling the truth, Dark would naturally not know the specific reason.

The faster recovery speed of mental power and magic power than before can only be attributed to the fact that people on the third or fourth front have made something that can increase the recovery speed.

Dark, who has almost recovered his magic and mental power, is ready to summon the remaining thirty-five people, stand on the magic circle and launch legion magic towards the wall of Buris.

But as soon as Dark raised his head, he was stunned.

There are six magic circles nearby that are arranged in a row and there is no magic liquid infused. What is the situation with the runes?

Dark's eyes followed the sound of shoveling.

A skeleton warrior put down the bone machete in his hand, picked up the bone shovel, and dug into the circular formation with shovel after shovel.

Beside the skeleton warrior, another skeleton soldier was digging a deep pit with a bone shovel in his hand.

The pits surround the magic circle and are arranged into six groups.

Facing the direction of the city wall of Buris, the soil shoveled by the skeleton soldiers piled up another slope.

The new necromancer apprentice from the 19th Mage Group directed a weaker skeleton to dig a hole under the slope.

Dalke didn't know what Guo Teng was doing.

But this does not prevent him from knowing what he is going to do from Guo Teng.

"19527!"

Dark's roar carried along the wind and reached Guo Teng's ears nearly 200 meters away.

Guo Teng immediately put down his movements and jumped on the skeleton soldier.

He grabbed the skeleton soldier's shoulder blades with both hands and stepped on the skeleton soldier's hips with his feet, like a will-o'-the-wisp boy riding a motorcycle, riding the skeleton soldier quickly in front of Dark.

The running skeleton stopped suddenly, and Guo Teng almost flew out due to inertia.

Just when Guo Teng fell from the skeleton soldier, Dark grabbed Guo Teng's collar and lifted Guo Teng into the air.

"19527, what are you doing?"

The severe bad breath caused Guo Teng to put on a mask of pain.

Captain, you look like a very clean person, could you please brush your teeth?

Seeing Darke's expression turn grim, Guo Teng quickly answered.

"Report to the captain, I am building a legal formation and trench defense."

Dark looked at the six magic circles that had not yet been filled with magic liquid, and could understand the meaning of the magic circle formation.

He could only understand half of the meaning of trench defense.

But seeing how quickly Guo Teng was able to dig out six magic circles and supporting runes, Dark felt that Guo Teng was a talent.

He decided to give himself some patience and let Guo Teng express his thoughts.

"Say your intentions quickly and you'll get rid of your codenames and put on names."

Dalke put Guo Teng down.

Guo Teng naturally expressed his intention.

"The magic circle arranged in a row is for the 19th Mage Group to fight guerrillas.

Because the canopy of the dead is thin near the city wall of Burris, the second front's long-range attack spells are traceable.

The defenders on the wall of Burris can calculate the starting point of the ballistic trajectory based on the ballistic trajectory of spells or engineering equipment shot out of the death sky, so as to carry out targeted attacks on the mages and ordnance on the second front.

With multiple magic circles arranged, as long as the members of the 19th Mage Group finish casting their spells, quickly go to the distant magic circle, and launch legion spells again, they can attack the enemy without any damage.

The enemies on the wall of Buris can only judge the location of the mage group through the spell tracks.

After casting a spell, go to a distance and cast another spell. The defenders on the wall of Burris can only passively follow the trajectory of the spell, thus losing the ability to tactically counterattack."

A piece of tactical analysis made Dark's eyes shine with a different kind of light in the darkness under the canopy of death.

He originally thought that Guo Teng was just a necromancer apprentice, but he didn't expect that he would have such insights in tactics.

However, what surprised Dahlke even more was Guo Teng's trench narrative behind it.

"If we can't move to a distant place quickly as planned.

Or if we are attacked by enemy stray bullets on the way, we can get into the cat's ear holes in the trench to withstand the explosive attack of the magic crystal cannon.

After the enemy's artillery fire attack is over, we can get out of the cat's ear hole, continue to gather, and release spells on the enemy."

Compared to the first-level necromancers and apprentices on the first front, the second line of attack suffered the greatest casualties on the Burris front.

Second-level mages, who are also low-level mages, no matter what type of mage they are, are the most difficult existences on the second front.

First, there is no money, second, there is no ability, and third, there is no family power.

If any of the three things are the same, then the second-level mage will not join the army, nor will he come to the battlefield of Burris to seek military merit in exchange for money, weapons and equipment, as well as meditation methods and various spells.
p>

The second-level mages on the second front pray hard every day, hoping that the magic crystal cannon on the wall of Buris City will not hit their heads.

After all, most second-level mages do not have as many means of self-protection as many people imagine.

In the low-level stage, everyone lacks methods to protect themselves.

Now, Guo Teng has brought you a different way to protect yourself.
