Luo Heng couldn't think of it.

The demons and the creatures of hell are no longer fighting, and they are constantly reinforcing their defenses.

“......。 Luo Heng is very speechless about this kind of thing, defensive battle. In the absence of air supremacy, defensive warfare is the share of death.

Without Luo Heng's order, the wurm continued to attack under the order of the dragon, but this hellish creature and demonic creature actually got up, and when they saw the large-scale wurm, they drilled into the fortress lair, and a small number of them actually counterattacked in the air, so that the wulong actually lost a lot.

"Talent!" Luo Heng felt that the commander behind this was a talent, but who was the person behind the scenes?

Will the devil rise up?

Will the creatures of hell survive?

In this case, the main plane would have been destroyed long ago.

Luo Heng flew directly over the demons and fortresses, in fact, the huge explosive ~ bomb of the cloud burst bomb did not have much effect on the demons and hellish creatures.

The demon plane is full of carbon dioxide and sulfide, and low-level professionals will be poisoned as long as they pass by the fire demon.

It's the same with the creatures of Hell, and the creatures of Hell, but colder.

"If only I could fill it with water. Luo Heng muttered in his heart.

Weapon No. 1 is certainly quite useful in the underground world, but the damage to the surrounding crust is too great, and if a huge volcano is created, it will be destroyed for thousands of kilometers around.

"It looks like it's going to be a fixed-wing aircraft. Luo Heng had a plan in his heart.

Helicopters are not suitable for this kind of attack, because the speed is too slow, and it is not cost-effective to come out together.

"Aerial gunboat!" Luo Heng turned his gaze to the side of the Brave Empire, the aerial gunboat was the most suitable at this time.

Why can't magic airships?

Magical airships are disturbed by magical fluctuations, and purely mechanical forces are only affected.

Just like when the gods are fighting, the other flying races don't dare to fly, and the magic power they receive fluctuates too much.

The air gunboat is still just a concept, of course, Luo Heng has a way, and it can be directly manufactured by nanorobots.

And if you have that energy, you'll have to use another version of Weapon One.

But it's also a good thing to make it, the air gunboat is a propeller aircraft, not a jet.

After being manufactured, it is equipped with a cannon, which is also a deterrent to the ground.

However, before Luo Heng could make a decision, the demons and hellish creatures launched an attack in the underground world.

Rat Demon!

A demon not much larger than the kobolds, covered in black scales, thousands of rat demons raided the kobolds' army.

The kobolds' army is vulnerable, and there are too many cannon fodder.

Fortunately, these elites are equipped with bayonets, on which they directly use cannons to carry out indiscriminate attacks.

"If you're dead, you're dead, and you're recruiting. Luo Heng saw the loss of the kobolds, he didn't have any expression, except for the most elite of these kobolds, the rest died when they died.

"More than 800 kilometers have already been occupied by the other side. The chief of staff spoke.

When Luo Heng heard this, he suddenly understood.

"Order, all personnel go up the mountain!"

"Those demons and hellish creatures are ready to attack us from underground. Luo Heng immediately understood that the earth's crust was indeed very thick, but for demons and hellish creatures, especially professional rat demons, it was not impossible to open a tunnel ten or twenty kilometers long.

The claws of the rat demons are very sharp, and these rat demons are driven by high-level demons, and it will not be long before they dig hard.

The people below heard Luo Heng's warning and ran up the mountain one after another.

New defenses soon appeared on the ridge, and these defenses were to break all the stones in the lower half of the mountain.

The formation of gravel, which is also discovered by the human alliance, so that whether it is a demon or a hellish creature, no matter how much strength, walking on such a mountain, it will be much slower, and when walking, these gravel will be unstable, and it will continue to go down the mountain.

In response to these, earth magicians are more popular, and they hire this kind of earth magicians or magicians with earth-based magic pets, or warriors.

The earth-based demonic beasts were burrowing one after another, listening to the movement inside.

Rumble!

Luo Heng didn't care, the fortress like the huge ant nest established by the two planes of the demon and hell was directly bombarded with the No. 2 weapon.

This kind of fortress is made of countless excavated rocks from the underground world, which is very troublesome, and if you want to say that the world building, no, it is the same effect as a cannon hitting stones.

Not only Luo Heng felt a headache, but the dragon also felt a headache, there were passages in the lair, demons, and hell creatures found the traces of the wurm and the dragon together, and fled one after another.

Luo Heng reconnoitred and found that the structure of the underground world here had been seriously damaged.

"If you fill it with water, the rocks that have been blown up down here will sink...... The key is where did so much water come from?" Luo Heng muttered in his heart.

There's a word called water ramming!

It is to directly irrigate the backfilled soil to achieve the purpose of tamping the ground.

This method is used in many real estate backfills.

"Do you want to build a reservoir?"

"The water in the reservoir is not good, after all, the underground world is extensive. "But the irrigation is not until it reaches a huge degree, and it reaches the maximum amount in an instant.

But this is not easy to achieve, nor is it easy to do.

"Shake!"

Luo Heng's eyes lit up.

There's a word called resonance!

"Battle armor, is there any way to release the resonance?" Luo Heng directly looked for the battle armor.

The passive warframe is like this, there is no intelligence, I think of it, ask, and the warframe will answer, otherwise the warframe will not give a solution.

"Magic Array. ”

"Magic!"

Warframe replied succinctly.

"What about the explosion?" Luo Heng asked.

"Yes. ”

"Give a design and execute the manufacturing order. Luo Heng said.

In less than five minutes, a circular weapon appeared.

"That's it?"

"Position this position!" the Warframe instructed.

When Luo Heng saw the location, he knew that he was in trouble.

"Changed places. ”

"The second alternate position, the cost increases ten,000 times, whether to implement. Warframe continued.

"Wait...... The second position, how big is the bomb ~ bomb?"

"Fifty tons. ”

"Forget it. "Luo Heng is speechless, fifty tons of things?

Really, I don't need money for energy?

Luo Heng decided to take a walk on his own.

Resonance is actually difficult to avoid in large buildings, and some large buildings look useless, but in fact, this problem is solved.

How powerful is the resonance?

Theoretically, even a huge aircraft carrier, or a huge building, has a resonant frequency that can destroy these things.

There are also bridges.

Therefore, Luo Heng can't destroy the current structure on a large scale, otherwise it will be in trouble at that time.

The wailing banshee was with Luo Heng, and Luo Heng headed towards his destination from the nearest entrance to the underground world.

The underground world is very lively now, and you used to walk for hours without seeing a single creature, but now there are levels everywhere or something.

And the entrance to the underground world here has been opened up to transport supplies or something.

Luo Heng entered the underground world, and the Black Dragon King led some black dragons, as well as the elite of the dungeon, to hunt those abyssal creatures.

Roar!

There was a huge roar, and the self-exploding demon spiders within thousands of meters around exploded!

As for these elites in the dungeon, they are mainly the dark elves, and the dark elves raised their staffs one after another and attacked the self-detonating demon spiders.

The underworld has been dealing with the abyss not for a year or two, but for many years.

Dealing with demon spiders, experienced.

"Your Majesty, the One-Eyed Tyrant is gone. "At this time, the Black Dragon King got bad news.

The One-Eyed Tyrant is the deepest monster in the underworld, and this monster is a huge eye, with countless tentacles, each with a small eyeball-like thing on it.

Spiritual Beast and is at the level of Holy Beast.

Illusion!

"Damn, I know. ”

Hurry up and deliver the news to Luo Heng. The Black Dragon King roared angrily and transformed into a human, wielding two huge golden scimitars.

As Luo Heng's most loyal trading partner and partner, the Black Dragon King got a lot of legendary-level weapons from Luo Heng's side.

At least several sets.

Puff puff!

One after another golden light, several huge abyssal demon spiders were killed.

"Kill!" the rest of the black dragons also struck.

In fact, the underground world is not friendly to huge monsters.

When Luo Heng received the news, he also scolded secretly, and then avoided a group of rat demons.

The underground world is in full swing, and countless rat demons have broken the excavated rocks into tiny pieces, and then rushed out through the underground river.

"A few hundred tons of cement in the carry-on space worked. Luo Heng muttered in his heart.

The underground river is huge, seven or eight meters wide and swims seven or eight meters deep, and now countless rock fragments have been thrown into it, causing the water flow here to skyrocket.

The rat demon was also afraid of water, so he threw some larger stones into it from a distance.

Luo Heng jumped directly into the underground dark river, and then swam upstream.

The cement was thrown directly into the underground river, and Luo Heng also threw a lot of fabrics into it.

As for whether the underground river can be blocked, Luo Heng is not very clear.

"I~, isn't it so unlucky?" When Luo Heng came to the predetermined location and there were still two or three kilometers left, he suddenly found that this place had been built into a huge underground space, the highest was fifty meters high, and the prototype of a temple was taking shape.

"It's about building a stronghold!"

"Build the altar!"

Luo Heng looked at the location and was about to probe.

"Roar!" A huge eye in the distance exploded~shooted~ a huge light and shone towards Luo Heng.

One-eyed tyrant!

This guy's perception of the soul level has actually reached a distance of a thousand meters.

Fly back!

Roar!

The Flame Giant, the Hell Demon King roared in anger, and countless hellish creatures rushed over one after another.

Luo Heng hurriedly ran, and there were at least thousands behind him
