After the Raven and Mars left the dock, they really didn't need to be operated, and the boat went straight down the river and set off for the other side of the underground river.

As soon as the ship left the area of the Silver Pine Valley, it entered a passage.

The passage was so narrow that it could only fit through an elven warship.

At the same time, because of the narrowing of the waterway, the speed of the current has also increased a lot, and the speed of the ship has increased all at once.

Coupled with the large number of gravel bends in the passage, if it weren't for the fact that the Fire Raven and Mars did not need to be controlled by sailors, the ship might have crashed into a nearby wall before it took a few steps.

After driving in such a black tunnel for about ten minutes, Chen Gu suddenly heard the sound of the mechanism opening in his ears.

Chen Gu looked up and found that an iron fence had slowly risen in front of him.

This startled Chen Gu, if he hadn't heard the sound of the mechanism just now, he wouldn't have known that there was still this hidden underwater.

Then Chen Gu understood that this was the defense method of Silver Pine Valley.

If it weren't for the ships of Silver Pine Valley, trying to enter from the upper and lower reaches of the underground river, they would be looking for death.

After passing the iron fence, they were considered to be out of the boundaries of the Silver Pine Valley.

After entering here, Chen Gu found that there was something different in the waterway.

From time to time, there are some strange sounds on both sides of the waterway.

Even from the top of the waterway, the sound can be heard.

Chen Gu looked out by the light of the fire of the two boats, and he saw some distorted black shadows lying on the stone wall by the waterway.

They twisted their heads and stared at the two elven warships, as if looking for an opportunity to jump onto the ship.

"Alan, get ready for battle."

Chen Gu informed Allen while ordering the Fire Raven he was riding to prepare for battle.

Gun doors quickly opened on both sides of the Raven, and the crow-like guns inside were pushed out.

At the moment when the cannon was pushed out, all the crow heads opened their mouths.

At this time, Chen Gu looked at the fire spirit crows that were only a dozen or so left beside him, and felt a little pity in his heart.

He was still too generous, if he wasn't so anxious to take the fire crow to craft the ship, maybe he could rely on the fire crow to sweep this piece over now.

Now all you can do is look at these Raven Cannons.

However, the Raven Cannon was launched, and the distorted black shadows quickly sank into the stone wall as if they had been stimulated.

Along the way, Chen Gu only saw the shadow of the enemy, but did not encounter the attack of the other party.

This made Chen Gu finally half relaxed.

Although he didn't know what those things on the stone wall were, it was clear that they had no intention of attacking the ship.

Then there is no need for Chen Gu to take the initiative to provoke the other party.

He just had his artillery ready, and he wouldn't be in a hurry when the enemy attacked.

In such a tense atmosphere, Chen Gu's ship did not slow down.

After a few rounds, the ship sailed into a darker passage.

The current of this passage was obviously more rapid, and Chen Gu clearly felt the impetus of the current.

At this time, Chen Gu had no way to stand on the bow of the boat, he clung to the railing beside him, and half-lay on the bow of the boat to look at the situation in front of him.

When he looked up, Chen Gu saw a bright light appear in front of him.

This is a sign to rush out of the channel.

The more this was the case, the more Chen Gu did not dare to be careless.

He didn't know what was going on outside, he commanded.

"Get ready, you're going out soon, and if you encounter an enemy, shoot me directly, and don't care about anything."

As soon as Chen Gu's words were finished, the light in front of him grew bigger and bigger, and finally Chen Gu's eyes turned white, and his boat rushed out of the passage and into a river.

The attack that Chen Gu imagined did not appear, he looked up and looked around, the sky was still gloomy and there was no sunlight.

The dazzling white light before was simply the contrast between the extreme darkness in the passage and the little light outside.

After entering the normal river, Chen Gu finally breathed a sigh of relief, the navigation in the passage just now scared him too much.

At this time, the Mars leaned to the side of the Fire Raven, and Allen, who was standing at the bow of the ship, shouted to Chen Gu.

"My lord, did you see those things in the passage just now?"

"See, it's good they didn't jump up, or we really don't have much chance of winning."

Chen Gu said with some concern.

"My lord, I always feel that they don't feel like enemies, but rather like natives living in the passages."

"That's just as well." Chen Gu thought for a moment and noticed the situation of those distorted black shadows.

Before Chen Gu launched the artillery, they did not take the initiative to jump down.

"And my lord, did you think that we went down the river, and this boat drove so smoothly, but what should we do if we want to go upstream?"

Hearing this, Chen Gu also understood, and he sighed secretly in his heart, his knowledge was still less, and some things were not as comprehensive as he thought.

This made Chen Gu's heart tighten, and he began to examine his situation again.

Chen Gu found that the caution he had since entering the lord world was gone, and now he had a feeling of letting himself go.

That's not going to work.

If Chen Gu only needs a city, then he can already go out like this.

But his goal is the Black Castle, the capital of the undead.

Not to mention the rest, just looking at the number of legions outside the Black Castle, these troops in Chen Gu's hands couldn't even deal with a fraction of them.

He's floating now, and he's going to do something to the enemies of the Black Castle.

Chen Gu, who understood this, suppressed the smile on his face.

"It seems that I am too relaxed, and your ship is following me on the road ahead of Alan."

Alan was stunned for a moment, he didn't understand why Chen Gu could suddenly say such a sentence.

He was about to ask about the situation, but found that Chen Gu had already taken out the map and commanded on the spot.

All the remaining fire spirit crows were sent out and flew towards the two sides of the strait to find out the situation on both sides of the strait.

At the same time, although the cannon doors of the Raven Cannons were retracted, all the Raven Cannons were actually not retracted.

Whatever happens, all the Raven Cannons can be fired once within a minute.

A second shot can be made within three minutes.

After ensuring safety, Chen Gu pointed to the river on the map and commanded.

Although he has not been a captain, fortunately these two boats do not need to be operated by him, as long as he points out the location.

Going south along the river, Chen Gu did not rest all the way, he had to ask for every information, and he had to judge every choice.

He acted like he didn't believe Alan.

In fact, only Chen Gu himself knew that he was honing himself.

Now is the time when he absorbs the most experience, and if he doesn't hone himself well at this time, he doesn't have to think about becoming a qualified lord.
