After all this, everyone was still elated, and they were even discussing the technique of double knives with each other.

After a simple freshening, the original smell of blood was replaced by bursts of daughter's fragrance in the base, and even I was magically refreshed.

"Are there any of these female warriors who haven't activated their spiritual powers?" I asked Lina beside me.

"There are probably dozens of them. Lena said.

"That's not good, within today, all the spiritual power will be activated, and now notify everyone to gather in the dungeon. I said.

"What about the progress of the work?" asked Lena.

"Sharpen the knife and don't mistake the woodcutter. I said as I walked towards the dungeon.

After a few minutes, all the female warriors have already gathered in the dungeon, and I chose this place because there is abundant spiritual power here, which is more beneficial for them to activate their spiritual power.

Lena and I explained to everyone again how to activate spiritual power, and even Lena and I joined the team.

The female warriors who have activated their spiritual power are naturally like me and Lina, helping other female warriors activate their spiritual power.

Sure enough, as I thought, the activation of spiritual power in this dungeon was much smoother, but when everything was over, the sky was also dark.

Although I was too tired to do it, I felt a sense of accomplishment when I looked at the dozens of female warriors who passed out on the ground.

"The construction period is suspended for one day, everyone will resume in the underground palace today, and I will explain to you the spiritual power elements by my side. I said to the female warrior who was standing.

Everyone listened very carefully, and I spoke very seriously, and Lena even started a live demonstration.

A group of female fighters began to train without taking a break, and if I hadn't stopped them in time, I guess they would have practiced until dawn.

"If you want to hurry, you can't reach it, so let's meditate first, starting with absorbing spiritual power. I said to the crowd.

So, everyone on the platform, including Lena and I, found a statue to sit down against.

If you don't know that the dozens of female warriors lying in front of you have fainted, this scene is a bit like what is going on in an excessive French style.

Under the careful guidance of Lena and I, more than a dozen female warriors had already mastered the spiritual power element at dawn, and although the power was still small, it was enough to make me happy.

To say that this dungeon is really mysterious, the female warriors who were in a coma yesterday because of the activation of spiritual power have all awakened now, and the female warrior who was slightly injured is also among them.

I simply let the female warriors who had just woken up rest in this dungeon, so that their recovery speed would definitely be greatly improved.

The other female warriors were a little weak except for those who had turned on the spiritual power element, and the rest were already a hundred times more energetic.

"Rest when it's time to rest, continue to build if it's okay, and we'll continue to cultivate later. I said to the crowd.

Anyway, the construction is also in this underground palace, even if you can't cultivate, just staying here will only be good for everyone.

The engineer has also encountered some minor problems with the development of vehicles to restrain the ugly mermaid, and I just took this opportunity to improve the combat effectiveness of the people.

After meditating all night, my spirit and spirit were almost recovered, and I personally instructed the female warriors who failed to open the spiritual power element how to control the spiritual power to break through their own element.

Under my guidance, the progress of female warriors has been rapid, and the number of female warriors who have opened the spiritual power element has also increased dramatically.

In fact, I had thought about cultivating these female warriors before, but at that time, the infrastructure was not perfect enough, and there were still savages, but now it is different, the mutant savages have been removed, and there are high walls and dungeon defenses.

Even if everyone is weak and has no combat effectiveness now, I don't have to worry about safety.

Two days later, all the female warriors had fully recovered their combat effectiveness, and even half of the female warriors had turned on the spiritual power element.

In this way, the training and construction team is enough to rotate, but the burden of construction naturally falls on the female warriors who have turned on the spiritual power element.

I will take the rest of the female warriors to continue to cultivate in the dungeon, so that they can break through as soon as possible.

But there are more important things waiting for me to do at the moment, because the beautiful engineer's transformed vehicle is ready.

On the third day, the sun rose, and Lena and I set out on our journey again.

"I've been busy training lately, so don't let go of the investigation. I said to Lena.

"Don't worry, I've already arranged it. Lena said.

"You're still thoughtful, I don't know what to do without you. I said with a smile.

Taking the transformed transportation, the mood of the two was relatively relaxed, and the topics they talked about along the way were naturally the same.

It is said that it is a new means of transportation, but in fact, the mechanical structure of the airship itself has not changed, but the beautiful engineer has added a shell to the airship.

Now the airship looks like a huge egg, and on the premise of ensuring defensive performance, observation ports are also installed in the front, rear, left and right, and a material that can see through light but is dozens of times stronger than glass.

And this shell is not a simple protective cover, the beautiful engineer has specially strengthened the waterproof performance, according to her words, this thing can be safe even if it dives to the bottom of the sea for 10,000 meters.

It's just that after pretending to be a shell, the power of the airship has been affected a little, but it is also a little.

Arriving at the cave again, we already knew the route to the underground river, and we didn't stop at all on the way, and went straight to the river.

"Are you nervous?" I asked.

"Don't be nervous, as long as you're around, I'm not afraid of anything. Lena said with a smile on her face.

That's right, it's still Lena who pilots the airship.

"Let's get into the water. I whispered.

Lena nodded and drove the new airship towards the river, which was very dark, but luckily we didn't rely on sight.

The beautiful engineer installed an echo pathfinding system on the airship, so that even if we couldn't see our fingers, we could move forward safely.

However, Lena still turned on the light, and the penetration of this light is also extremely strong, the visibility was originally only three or four meters, but now it has become more than ten meters.

It's just that we haven't seen ugly mermaids yet, and they probably didn't expect us to dare to come directly into the water to fight them.

There was nothing to see in the river except water and water, and if it weren't for the bubbles from the power system outside the window, I would have thought we were staying where we were.

After a few minutes of driving, the ugly mermaids appeared, and this time I finally saw their numbers.

Because of the dense black pressure on a large area, it overwhelmingly attacked us directly.

The airship was constantly being hit violently, and I could tell that Lena was a little nervous, but in fact I was nervous at the moment.

After all, the impact sound is indeed a bit scary, but fortunately, the safety monitoring system of the airship has not indicated that the hull is damaged.

But looking at the ugly faces in front of me, to be honest, my heart is still a little panicked.

"There are too many. Lena said.

"Can you walk?" I asked.

"Movement is movement, but the speed is at least half slowed down. Lena said.

"Looks like it's time to try our weapons systems. I said with a smile.

"You can still laugh. Lena frowned.

"Don't worry, if there is really any danger, we will have no problem saving our lives. I said.

"Oh well. Lena said as she turned on the weapon system.

"Wait, let me do it first. I said as I clasped my hands on the two handles that had been reserved in advance.

In fact, the weapon system of the airship is also an electric current attack, but I want to see if my human current has improved a little in the past two days.

The beautiful engineer designed two attack systems, and the starting point was also to be foolproof.

As soon as the words fell, I had already turned on the spiritual element, and with the blessing of the external materials of the hull, my current was amplified a lot.

The ugly mermaid blocking our way was instantly repulsed, and for a moment the speed of the airship returned to its normal state.

"Do you really feel the need to explore? Do you think it's possible for your enemies to get in with such a hard time that equipment like ours is traveling?" asked Lena.

"I don't know, I just feel that something is wrong, and I don't feel sure if I don't go to see me. I said as I released the current again.

The ugly mermaid in front of us was forced back by us, but it had been walking along the river for a long time, and there was still no shadow of land.

"I don't know where this underground river leads, or how long it will take. Lena said.

"After another two hours, if there is still no land, we give up. I said.
