Ballista, which is a relatively common large-scale war machine, has a very complete lifting system.

Its lethality fluctuates with the type and level of the ballista.

With the sense of threat fed back by his intuition, Yi Qiu estimated that the level of the ballista in the dwarven fortress should not be too high.

The high-level ballista is able to launch a very lethal attack on the low-level dragon species of the white dragon, and can achieve a considerable armor-piercing effect for heavily armored units.

Of course, this kind of ballista is not something that ordinary people can handle.

For the driver, this type of ballista has very strict requirements.

Like general-purpose large war machines, they all have corresponding advanced classes.

As for the ballista, there are advanced ballista masters, elemental magic crossbow pilots, etc.

This advanced class is generally common in armies, and can give war machines additional lethality and accuracy.

In a small-scale war, it is a more dazzling battlefield focus than the advanced corps.

However, as a secret realm with a comprehensive challenge level 10, it is unlikely that you will encounter such an enemy.

The Dwarven Fortress has a relatively narrow entrance, which would be difficult to enter for a size like Lev.

Although it is certain that the inner area of the dwarven fortress is not so narrow.

But for now, they don't know the length of the entryway.

In unusually narrow passages, it will appear passive if it is ambushed or trapped.

In a previous discussion, Lev decided that using an RPG to blast through the outer wall and then raid it was a relatively high success plan.

However, due to the threat of the ballista and the difficulty of the leader's challenge, the three of them decided to wait a week before opening up the wasteland.

Because the refresh time of the dungeon is one week, a week is just enough time to brush a wave of dungeons, and you can get a chance to improve.

After all, the challenge level of the dwarf fortress was 10+, and their previous highest level of Yi Qiu was only level 7.

The difference between the challenge level and the comprehensive network recommendation is a bit big, and the probability of being able to clear the level is relatively low.

Now, Yi Qiu is already level 9, and Lev is also level 7.

Emma needs to consume general experience to activate bloodline spells, so the level increase has been relatively slow.

But now, Emma's Warlock level has also been raised to level 6.

And the 3-ring spell she awakened was undoubtedly the fireball spell she had been looking forward to for a long time.

With her bloodline ability, she is able to consume 2 fireball spells to transform it into a powerful fireball spell.

As an upgraded version of the Fireball Technique, the lethality of the Powerful Fireball Technique is almost one of the best in the low-ring spells.

However, because the flight speed of the fireball has not changed, there is some room for evasion for Yi Qiu, whose movement speed has now entered a new level.

In the shadows at a distance from the dwarven fortress, Lev is looking for a strike point for the dwarven fortress.

As a retired member of the Alpha Rangers, Lev's qualities in this regard are outstanding.

He needed to find a location that would allow them to penetrate deep into the dwarven fortress after being blasted with an RPG, not too high, not too far, and not inside the building.

If it was too high, it would be very difficult for them to enter the dwarven fortress through this passage.

If they are too far away, they will be greatly affected by Ballista.

Inside the building, they may face the dilemma of a dwarven fortress entrance.

Therefore, it is a difficult choice.

After weighing everything for a while, Lev chose a wall to the east of the dwarven fortress as the point of attack.

Judging from the distribution of the firing ports in the vicinity, the density of buildings in that area is relatively sparse, and it is not too far from them, and the height is moderate.

After selecting the strike point, he pulls out the RPG from his item backpack.

Compared to the Ballista without enhancements, the effective range of an RPG is higher.

Because of the lack of fluorescent plants nearby, the darkness perfectly concealed Yi Qiu's whereabouts.

Creatures living in the underground space all have dark vision, but for dwarves, the effective observation range of their dark vision is not that far.

Lev took out the rocket, and then aimed for a while.

"Whoosh!"

In a burst of dazzling fire and thick white smoke, the rocket rushed towards the dwarven fortress with extremely fast acceleration!

The dust on the ground nearby was shaken by the reaction force.

Yi Qiu, who was barefoot, could feel that there was an obvious vibration on the ground, but the amplitude was not large.

"Bump!"

And as the rocket hit the top of the city wall, there was a violent explosion!

The dazzling white light dispelled the darkness near the city wall, and the main structure of the city wall was damaged a lot, but it did not form a relatively complete passage.

RPGs are better suited for attacking and destroying buildings than against mobs.

The sound of a violent explosion was very harsh in the empty underground space, and the firelight emitted by the PRG also revealed Yi Qiu's location.

“biu！”

“biu！”

“biu！”

There was a sharp sound of breaking the air in the air, and the shooting port in the dwarven fortress blatantly attacked Yi Qiu and them!

Although this distance is more than the effective attack range of most unenhanced Ballista, the damage of the Ballista will be reduced beyond this effective attack range.

However, even with this reduction, the bolts fired by the Ballista are still lethal to light and unarmored units.

At this time, Yi Qiu and the others had already moved behind the large stone block next to them.

"Bump!"

In a plop of small rubble, a thick crossbow bolt next to it shot firmly into the ground.

Yi Qiu wiped the dust off his face and observed the crossbow arrow.

Its length was much shorter than Yi Qiu expected, but it was thick.

In a sense, it fits well with the dwarven style.

Although they belong to the small race, the impression given by dwarves has always been rock-solid.

They are not like ordinary small people, who rely on their superior agility to compensate for their physical weakness.

Instead, they used heavy punches and tough flesh to knock down those who mocked them, and once refreshed people's perception of the villain.

At this time, the ballista of the dwarven fortress has finished firing, and it is in the interval to reload the crossbow arrows.

Obviously, the dwarves driving these ballistas were all black car drivers who drove without licenses, and the only attack they sent out was a crossbow arrow near Yi Qiu.

Lev rolled out from behind the rocks, and after carefully observing for a while, he quickly aimed the loaded RPG at the dwarven fortress.

"Whoosh!"

In a fierce puff of white smoke, the rockets rushed straight towards the crumbling walls of the dwarven fortress!
