"Okay, don't look at it, let's get on the boat."

After completing the synthesis of the Holy Scale Submarine, Chen Gu turned his head to look at Allen.

At this time, Alan was speechless.

He didn't expect Chen Gu's synthesis to reach such a point.

However, for Chen Gu, this is all basic operation.

After greeting Allen, Chen Gu jumped onto the Holy Scale Submarine by himself.

Unlike the Fire Raven and Mars, the Holy Scale Submarine does not have automatic operation functions.

Chen Gu needs to do it himself.

So he still needs to go down and get familiar with the operation first.

Seeing the situation in front of him, Alan didn't say anything more, jumped onto the deck of the Holy Scale Submarine, and entered the interior of the submarine.

"The upper level is the operation area, you wait and help me watch the road in front of me, and I'll take the helm."

Chen Gu pointed to the location of the window in front of him and said.

However, Chen Gu had already thought about it, and after this time was completed, he would have to find a captain and let him help salvage things underwater.

Alan didn't know what Chen Gu was thinking, and he stood at the window and looked outside.

"My lord, what should we do now?"

"You wait, check that all the sealed hatches are completely closed."

Chen Gu pressed a button on the side of the rudder.

When the light on the button turned green, Chen Gu turned on the water injection switch on the side of the rudder.

The sluice gates of the watertight compartment on the lower level opened, and a large amount of lake water poured into the watertight compartment on the lower level, and then Chen Gu's Holy Scale submarine began to sink slowly.

After the Holy Scale Submarine had completely entered the water, Chen Gu looked at Allen's side.

"How's that, can you see clearly?"

"Yes, but we'll have to sink a little bit more."

"Okay."

Chen Gu pushed open the sluice gate of the watertight cabin again, increasing the amount of water irrigated a lot.

When he sank ten meters deep into the lake, Alan called a halt.

"You can try to move around."

Only then did Chen Gu push the switch for the ship to move forward, and the Holy Scale Submarine writhed like a swimming fish.

"We're going to go a little bit left."

"A little more to the right."

Alan said as Chen Gu controlled the Holy Scale Submarine.

But one of them is a navigator who knows nothing, and the other is a novice helmsman.

The two of them don't work well together.

While the Holy Scale Submarine was moving underwater, the path was crooked.

However, as Chen Gu and Allen Quan cooperated with each other for a longer time, the Holy Scale Submarine also became smooth to move underwater.

It didn't take long for Alan to find out about the situation.

"Stop, I see something ahead."

"What is it?"

Chen Gu stopped the boat and ran to the front window, "Is it the fruit of the World Tree?" ”

Chen Gu and the others came here to find the fruit of the World Tree.

According to Allen, when the elven nobles die, their souls enter the World Tree, which the elves call the sacred tree.

After that, fruit will grow on the World Tree.

Although it is not explicitly stated, it is very likely that it was the embodiment of a dead elf.

After the World Tree fell, all of these fruits were gone, and Chen Gu had reason to believe that all the fruits had sunk to the bottom of the water.

Thinking about the aquatic plants found on the World Tree, Chen Gu knew that these fruits would not rot.

No matter what the effect of these fruits is, as long as these fruits are found, it will be a good thing for Chen Gu.

It would be even better if he could use these fruits to get some High Elves.

In this way, Chen Gu had enough combat power to deal with the undead of the Black Castle.

So Allen's discovery made Chen Gu nervous.

He was curious to know how many of the fruits had fallen into the water.

But when Chen Gu came to the window and looked out, he found that he seemed to be thinking a little wrong.

In front of the Sacred Scale Submarine, it was not the fruit that sank into the lake.

The face is a palace built underwater.

The palace occupies a fairly large area, and it was built on the foundations of more than a dozen nearby islands.

It looks like a small elf city.

Of course, the small size mentioned here is actually compared to the holy lake outside.

If this palace is to be compared to Silver Pine Valley, the six Silver Pine Valley combined are not as big as this palace.

"What is this?"

Chen Gu swallowed his saliva and looked at the situation below.

"I don't know, I've never been to this side of the Holy City."

Alan didn't know what was going on here.

Chen Gu glanced at where he was now.

They are located on the left side of the palace.

Turn a little further to the southwest and you will see the main hall of the palace.

"What's up there?"

Chen Gu pointed upward.

Alan thought for a moment, looked out of the window again, and finally said, "The island where the sacred tree is planted, but it shouldn't be, what about the fruit of the sacred tree?" ”

"I don't know, but let's go down and take a look first, this palace looks like it's been soaked underwater for a long time, maybe there are some clues here."

Chen Gu said as he returned to the rudder of the ship, controlling the Holy Scale Submarine and heading towards the main hall of the palace.

When the submarine headed in that direction, Alan immediately noticed that something was not right.

"My lord, be careful, the palace seems to be moving."

As soon as Eren finished speaking, several blue spells shot out from the magic towers around the palace.

Hit the Holy Scale submarine with precision.

Then Chen Gu only felt the Holy Scale Submarine shake, everything was out of control, and the Holy Scale Submarine stopped in the water.

"Hell."

Chen Gu scolded secretly and kept turning the rudder in his hand.

However, he found that the rudder had clearly lost its effect, and could no longer control the Sacred Scale Submarine forward.

"My lord, the submarine is frozen."

Alan also discovered the anomaly here at this time.

"It's okay, let's float."

Chen Gu snorted and quickly turned on the drain switch.

Although the Holy Scale submarine cannot be moved, the function of draining water can still be used.

As the water poured into the watertight compartment was discharged, the Holy Scale Submarine quickly surfaced.

Chen Gu looked at the palace below, feeling a little unhappy in his heart.

"Go and find out what's in the palace."

As he spoke, Chen Gu released a school of white-scaled fish and water elementals.

Allen, who had been watching from the window, saw schools of white-scaled fish and water elementals enter the palace with his own eyes.

Like the Holy Scale infiltrator, they are fine when they are not close, but as long as they get close to the palace cordon, they are directly frozen into ice by spells.

Even the smaller white-scaled fish were not spared.

Not to mention the larger water elementals.

Listening to Allen's description, Chen Gu laughed instead.

"Isn't that a good thing? The water of this sacred lake will restrain the undead, and this palace can still be used, so now there is still the power of the elves under the holy lake, which is a great help to us. ”
