"Master, because the energy tower has been interfering, it is temporarily impossible to detect other metals. However, according to my calculations, there may be a large amount of metal stored under the energy tower."

At this time, Aya's voice came out directly.

"Haha, Afan, maybe there will be a good harvest next time. If I'm right, under this huge energy tower, there may be a warehouse for storing brass essence and profound iron essence.

After a while, you first call out a few metal robots for detection, so as not to leave this base with special attack methods.

With such a big steel city and such a huge energy tower, even after countless years, the remaining energy may be fatal to you. "

Xiao Gu also said with a smile at this time.

"Yeah, I understand."

Nodded, Zhang Fan naturally knew that what Xiao Gu said was the truth.

"Aya, call up a few metal robots and go directly to the area where the energy tower is located to conduct detection."

At this time, Zhang Fan also directly ordered Aya.

Although perhaps the metal robots in the Tamron are more powerful, those metal robots are more precious and of great value, so they are reluctant to use it easily.

The temporary role of the metal robot is to test whether there are other attack methods in the steel city near the energy tower and the surrounding steel city. Naturally, the metal robot possessed by the Black Dragon itself is sufficient.

"Okay, Master."

Immediately afterwards, from the top of the Black Dragon, a small hole appeared directly, and immediately, three rays of light flashed across his face, and it directly fell near the energy tower.

Immediately afterwards, among everyone's surprised eyes, three metal robots with a height of about one and five meters appeared directly in place.

After that, it probed the surroundings a little bit.

"Master, found an entrance, but because it was too long, it was already covered by a lot of smoke and dust, and after detection, there was a gate at the entrance."

Soon, Aya's voice came directly.

"Very well, Aya, just let the metal robot push the door open. If you can't do it, then put it away. It's not too late for me to do it myself."

Zhang Fan said immediately.

After that, Aya directly controlled the three metal robots, stood in a row, and pushed hard against the entrance door.

Although these robots seem to be relatively small, each is strong enough to reach the late stage of the Star Jubilee realm. Especially its power, if it bursts out with all its strength, it is even more powerful than the Nine Star Noble Realm.

The three combined forces are almost the same as the random blow Zhang Fan can now play.

"Boom!"

The three metal robots pushed the huge gate made of alloy forcefully, and the ground around them was shaking at this moment, dust was filled, and the sand fell a little bit.

"Shoo!" "Shoo!" "Shoo!"

At this moment, suddenly, a dozen or so white lights directly enveloped the entire gate area. Among them, a few shots also hit the three metal robots, and directly penetrated the metal robots completely, making Zhang Fan It was also taken aback.

"It's a powerful attack. Although these three metal robots are only the lowest level, their defensive power is not inferior to those who are stronger than the star and moon realm. At this moment, they are directly penetrated. If I stand There will be danger if you don't know."

Zhang Fan said with a surprised look at this moment.

"This should be regarded as the last resort. The door has already been pushed open. Go in now and see what's inside."

Xiao Gu also said with a voice at this time.

Nodded, Zhang Fan's figure moved, and he walked towards the entrance in an instant.

After entering the entrance, Zhang Fan also found that there was an open tunnel in front of him, enough to accommodate three or five people at the same time.

All the way forward, after a few minutes, Zhang Fan's front also became clear, and a huge open area also appeared in front of Zhang Fan.

In the surroundings, countless metal pipes are intertwined, which looks very complicated.

"Yes, here is already stopped because there is not enough energy. But Afan, in order to ensure safety, you will control the flying knife for a while and directly cut off the energy supply here to avoid abnormal situations. "

Xiao Gu's voice also came out directly at this time.

"About a hundred meters on the left."

"One hundred and thirty meters on the right."

"Forty-nine meters ahead."

"Five-eight meters behind."

"boom!"

"boom!"

"boom!"

Soon, Zhang Fan directly controlled the flying knife to drop the several energy supply lines around Xiaogu's prompt and cut it directly from the middle.

Fortunately, it is very strong here, and it did not collapse due to the huge force.

"It's all resolved, the next step is the harvest time. Afan, have you seen those huge warehouses? Come, important things must be hidden in them.

Judging from its scale, it must not be ordinary brass and mysterious iron. There is only one possibility, that is, metals that surpass the two, and most likely it is brass spirit and mysterious iron spirit.

For such a large warehouse, the content of the two may add up to more than 10,000 tons. "

At this time, Xiao Gu also said immediately.

At the same time, Zhang Fan also moved and landed directly in front of the warehouse in front of him.

"Give me, break!"

Immediately afterwards, Zhang Fan directly used the power of his mind to control five flying knives in front of the two huge warehouses, combined them according to a specific operation route, and bombarded the door of the warehouse.

In an instant, two openings appeared in front of Zhang Fan.

And Zhang Fan, the first time he used the power of his mind to detect the situation inside.

"Haha, Xiaogu, it's posted, and it's full of brass spirits and profound iron spirits. Obviously, the things in this warehouse have not been taken away."

In an instant, Zhang Fan couldn't help laughing.

At the same time, Zhang Fan also directly controlled the flying knife, and directly cut the door of the entire warehouse out of a hole the size of a normal person, and immediately walked in.

"Yes, so many brass spirits and profound iron spirits are enough to support your cultivation for a short time. Anyway, didn't you get everything from the old master?

At that time, go directly to the universe bank to take out the wealth of the previous layer, which is enough to support you for a long time.

Now, start to collect it directly and transfer all of these to the Dantian space. "

Xiao Gu also said immediately at this time.

"brush."

Then Zhang Fan immediately moved his mind, and immediately began to collect a large amount of brass essence and profound iron essence into the star source debris space.
