As the saying goes, seeing is believing. Since Fang Zheng asked, Nymph naturally found the video footage of the incident and played it.

"This is the image captured by Explorer No. 2333 in the waters of District 15."

As Nymph explained, Fang Zheng saw on the screen in front of him a seabed covered with all kinds of seabed plants. He could even see all kinds of fish swimming around. The data next to it also showed the depth. At first, the depth of Tanji 2333 was still 500 meters, then gradually went deeper to 1,000 meters, 1,500 meters...

As Tanji gradually slid down the seabed, the surrounding scenery began to change. At first, he could see all kinds of seabed plants and fish, but as he went deeper, the water plants and coral reefs that were everywhere gradually disappeared, and even the shapes of the fish began to become strange. Fang Zheng even saw a few huge monsters that looked like whales, but they didn't seem to be aggressive. Maybe they just regarded Tanji as some kind of small fish and didn't care.

“Ding ding ding…!”

At this moment, a warning sound rang out, and at the same time, Tanji seemed to have discovered something. It quickly changed direction, and then "jumped" directly off the cliff, reaching 5,000 meters in the sea. There was no light here, but Tanji's own dark detection still allowed Fang Zheng to see the surrounding situation clearly.

Then Tanji 2333 quickly sent out a search signal in all directions, and then it seemed to have found the direction and began to move towards the direction of the large crack on the other side of the seabed. Then it drilled into a cave that looked about one person tall. After passing through a long passage, suddenly, everything in front of it suddenly became clear.

"This is……"

Looking at the scene in front of him, Fang Zheng's eyes widened in surprise. After passing through the narrow cave, a huge hole appeared in front of Tanji No. 2333. And around the hole, you can see spirit crystals shining with magical brilliance everywhere! The largest of them is as big as a house, and the smallest is as big as a basketball. Judging from the brilliance emitted by these spirit crystals, their purity is also quite high!

This is a treasure!!

At this moment, Tan Ji's perspective turned again, and then it seemed that it was going to take some samples back for analysis. But just when Tan Ji was about to collect the spirit crystal samples, the picture suddenly turned, and then it became completely black.

"…What's going on?"

Fang Zheng was stunned at the black screen in front of him, and Nymph explained at the right time.

"At this moment, the signal from Tanji 2333 was interrupted and disappeared."

“…So soon?”

Fang Zheng was also shocked to hear Nymph's answer. That was a Tanji! Every Tanji was equipped with a plasma shield! Even if the monster was powerful, the Tanji could withstand one or two attacks, but this one was killed instantly before she could react?

"After that, I sent out another team of six Tanji to search the target area again."

As she spoke, Nymph opened another video. This time, six explorers formed teams of three and searched along the route where the previous explorers had been "killed". As before, when the explorers arrived at their destination, they did not encounter any danger, but when they began to try to collect the spirit crystal ore, they were suddenly "killed instantly".

However, this time, because Nymph had made preparations in advance, they were able to send back images of the attackers before these explorers were "killed" - just as the explorers began to collect spirit crystal ore, more than a dozen tentacles of different sizes suddenly shot out from the depths of the dark caves around them, directly pierced these explorers, and then rolled up and retracted... It probably took less than two seconds.

"There is actually such an operation..."

Looking at the less than two seconds of footage, Fang Zheng was also shocked. Was he watching an extremely deep cold? What the hell was this?

"After that, we explored the area again and found a huge monster hidden under the earth's crust... It looked like some kind of soft-bodied creature. From what we could see, it seemed to be living here specifically, raiding and catching creatures that occasionally entered it for food... It was about... this big."

As Nymph spoke, the scene in front of Fang Zheng soon turned into a map, and then Nymph stretched out her hand and drew a circle on it...

"puff!!"

When Fang Zheng saw the red circle marked on the map, he spat out a mouthful of water.

“Is this thing this big?”

"At least judging from the life fluctuations, it's about this big..."

No wonder Fang Zheng was so surprised, it was because... this area was at least as large as three football fields!

What the hell is this monster? It’s as big as three football fields. Are you kidding me?

Although the monsters in deep-sea monster movies are all long and bulky, they shouldn't be as long as this!

In addition, one tentacle of the opponent is enough to kill Tan Ji in seconds... Looking at its appearance, I don’t know how many tentacles it has.

"In other words, this thing has taken over an entire vein of spiritual crystals and used it as its shell? And then it hides inside and launches a surprise attack. How can this be done?"

Looking at the 3D analysis chart on the screen, Fang Zheng was at a loss. If this monster was like the one in the fairy tales that guarded the magical herbs, it would be fine. Fang Zheng could just use a soul stone transformation to kill it. But now it was cunningly using the entire spiritual crystal vein as a tortoise shell, which made the situation troublesome for Fang Zheng. Although Fang Zheng was sure that he could definitely kill it with a slap using the Star Forging Dragon King, but that slap would shatter his spiritual crystal vein into powder...

Similarly, the KanColle can't help this time, let alone Kurumi, Yoshino and Illya, because tentacles are specifically designed to counter magical girls...

As for the Soul Stone in my hand...

Fang Zheng rummaged around and found that the only thing that could be used was... Masail.

Since that thing needs to eat, it must be alive. If it is alive, then the angel of death can just kill it with a sickle. Wouldn't it be easy and convenient to dig up the corpse or do something else?

"Wait for me to get it done, and you guys get ready to mine!"

Thinking of this, Fang Zheng made a decisive decision. He didn't believe that he, Masail, couldn't kill a large tentacle monster alone?

Fang Zheng also acted decisively and acted immediately. After determining the next target, he immediately boarded the Sea Mist battleship and arrived at the target area.

But...

"…Why the hell didn't I think I have a fear of the deep sea?"

Looking at the dark sea outside the porthole and the huge black shadow passing by under the light, Fang Zheng always felt his calves trembling a little. Although it is reasonable to say that Iona's warship is very safe, even if there is a starship bombardment, but for some reason, it feels less safe on the seabed than in space.

But then again…

"Iona, why did you shrink?"

Looking at Iona sitting next to him, Fang Zheng asked curiously. When Nymph learned that Fang Zheng was going to the target sea area to deal with the huge monster, she suggested that he take Iona. Fang Zheng originally thought that it was a bit of a waste of talent to go on the battleship, but when Iona's ship came over, he was surprised to find that... the hull of this little guy had shrunk?

After the second modification, Iona was a Hell Angel-class battleship several thousand meters long, but now she has shrunk to a 300-meter-long Eternal Annihilation-class battleship...

"It's Ms. Musashi's decision."

In response to Fang Zheng's doubts, Nymph beside him quickly gave an answer.

"According to Ms. Musashi, because Ms. Iona did not complete the mission, she was demoted. Currently, the Hell Angel class is under the control of 400 and 402, and Ms. Iona was sent to the Eternal Annihilation class..."

“…”

At this moment, Iona also turned around and nodded at Fang Zheng.

"I made a mistake, so I have to be punished. According to Musashi's intention, I should have been sent to clean the toilet..."

"...I didn't expect your mental models to be so rigid..."

Fang Zheng really had nothing to say about this. Although these mental models looked like cute girls on the surface, their behavior was completely like that of a tough military officer.

However... the army has its own rules, so Fang Zheng naturally couldn't say much.

"Iona, we have arrived at our destination."

At this moment, accompanied by Iona's voice, the warship slowly stopped. Then the lights came on, illuminating the dark rock bed below. Looking at the dark environment outside, Fang Zheng couldn't help swallowing.

Deep-sea phobia is really terrible...

"Well, I'll be back soon... By the way, get ready."

As he spoke, Fang Zheng reached out and opened the Dimension Code.

Then he activated the Death Angel Soul Stone which had not been used for a long time.
