"No doors?"

Chen Gu, who retreated to the ground, shook out Allen and asked about the situation, Allen was silent for a moment and finally gave an answer.

"There is really such a thing, in order to prevent someone from cheating the door, in wartime, unless it is a hero of the city, other heroes really can't open the city gate.

But it's also a good thing, it shows that Silver Pine Valley hasn't been taken over by the undead. ”

"How far can this be prepared?"

Chen Gu is more concerned about this.

"The gates are closed, flying creatures can't enter, the underground is impassable, all the sewers are fenced, and nothing but air can enter the city." Eren knows very well what the state of the elven city will be when it is closed.

"Does it consume a lot of energy?"

"No, as long as it is closed, the energy can be circulated internally, which is prepared to ensure that it can fight for a long time, and even food and water are ready."

Listening to Allen's words, Chen Gu was already a little disappointed.

But he was still unwilling and wanted to try again.

"Give it a try, maybe after all these years, the wartime ban has been lifted."

"No, I'm not going to go from the valley side, I'm going to go to the top of the Silver Pine Valley and try it."

Chen Gu calculated the top position of the city of Silver Pine Valley based on the positioning he had done at the gate of Silver Pine Valley before.

And with his men, he came here in a carriage.

"Necro vine, drill down, drill down."

Under Chen Gu's orders, the nine ghoul vines began to burrow deep underground.

Alan had been paying attention to Chen Gu's reaction, and when he heard Chen Gu's order, Alan sighed.

"Why bother, you don't know how well the elves will defend the city."

"I don't know any of that, but I know one thing, the most powerful magic is time, and the most powerful power is nature."

Chen Gu affirmed, "No one can escape the erosion of time, and no object can escape the weathering of nature.

Silver Pine Valley is located underground, corroded by underground rivers, this is what you said, then it proves that the earth will also be affected by nature, I don't know how many years the undead have appeared, but in this year, no matter how tightly defended, there will always be some changes. ”

Hearing Chen Gu say this, Alan didn't say anything more.

Chen Gu looked at the position where the corpse vine had burrowed for a moment, then turned his head to the Blood Shadow Wolf and the Fire Spirit Crow and said.

"You guys go down and look for food on your own, I'll wait in the carriage, the fire crow pay more attention, if there is an enemy, monitor it first and then come back to report."

After speaking, Chen Gu returned to the carriage.

When Chen Gu got into the carriage, many vines quickly appeared around the carriage, and these vines hid Chen Gu.

This is the hidden mode of the carriage, which allows the stopped carriage to become a nearby scenery and eliminates the smell of passengers in the carriage.

As long as it's not anything transparent. Outrageous means such as eyesight, normal people cannot detect the existence of the carriage.

Chen Gu knew that it was impossible for the Nechoul Vine to complete his plan in a short period of time.

He needs to wait here for a few hours.

Before that, Chen Gu could get a good night's sleep.

"Actually, I think you can go up the river, maybe you can find a way into the Silver Pine Valley from the river."

After entering the carriage, Alan was still trying to persuade Chen Gu.

But Chen Gu didn't have the idea of listening to his opinion at all.

"I know there's access to Silver Pine Valley from the river, but do you think no one has thought about it for so many years?

My guess is that the river channel of the Silver Pine Valley has some arrangement both upstream and downstream.

Maybe it's a labyrinth that people can't get out of, maybe it's a waterfall with a huge drop, in short, you can find Silver Pine Valley from the underground river, but it's a big problem to be located.

On the contrary, my plan has some viability, at least Silver Pine Valley is at our feet.

All we have to do now is wait, wait for the ghoul vine to return. ”

Eren didn't have a problem either, anyway, he was in a state of mind now, and he didn't need to hurry, and he didn't need rest or food or anything.

Chen Gu is willing to try, so let him try.

Seeing that Alan was quiet, Chen Gu also put the crystal forward with satisfaction, and collapsed on the bed and closed his eyes.

This sleep, Chen Gu slept for about six hours.

He woke up when he heard a knock outside the carriage.

After sleeping for so long, Chen Gu can be regarded as having enough spirits.

After sitting up, Chen Gu did not open the car door, but sat to sober himself up for a while, and then pushed the car door and walked out.

As soon as he got out of the carriage, Chen Gu realized that it was a corpse vine that was striking the carriage.

Looking at the situation of this corpse eater, Chen Gu's eyes lit up.

"Have you found the entrance to Silver Pine Valley?"

The ghoul vine cannot speak, but has a consciousness of its own.

As soon as Chen Gu asked him, the corpse eater vine immediately nodded.

Chen Gu glanced at the Necro Vine again and found that only one of the nine Necro Vines he had sent out had returned.

"Are the others already down?"

The ghoul vine nodded again.

"Can the carriage pass?"

This time the ghoul vine didn't answer.

Looking at the appearance of the corpse eater, Chen Gu said directly: "Forget it, you lead the way in front, I want to go over and have a look." ”

After saying that, Chen Gu returned to the carriage, and this time he sat in the front row.

"Keep up with the Necro Vine and use the Underground Movement Mode."

As soon as Chen Gu's order arrived, a coachman appeared in the coachman's position.

He shook the whip in his hand, and the carriage sank into the ground.

Chen Gu, who was sitting in the carriage, saw the dirt lined up in all directions, leaving a passage for the carriage.

That's the ability to stealth underground.

It's just that unlike running on the ground, the carriage moves at a speed of only thirty kilometers per hour.

However, this is enough for Chen Gu.

Led by the Necromancer, the carriage was heading towards the depths of the earth.

Chen Gu looked out the window, and he found that his guess was correct.

Nothing has escaped the ravages of time and the power of nature.

In recent years, the impact of wind and rain on the earth is still very great.

The rainwater flows down the roots of the trees into the earth, and some of it becomes nutrients for the trees, while others penetrate deeper.

Over time, a layer of water was formed between the soil and the stone layer.

And this is exactly the opportunity that Chen Gu is looking for.

This water slowly dripped through the cracks in the stone into the valley of the silver pine.

One, two, three......

Maybe one or two drops of water, the impact is not great, but it breaks the elves' magic on the ceiling of Silver Pine Valley.

Because for the arrangement of Silver Pine Valley, the water droplets are not very powerful and do not have much impact, so there is no need to be guarded.

It was this that did not need to be guarded, and it was forced to cut a hole above the Silver Pine Valley.

A ghoul vine that can pass through.

And now Chen Gu's carriage is also passing through here.
