Xiaoli immediately commanded the Dafei to rush outside the city and arrived in front of this short, pointed facility with only half of the spire exposed. Of course, the spire has no door, and the yellow sand must be dug away.

Although digging yellow sand is a simple action, just like moving a corpse, it also requires skills, production skills. Both players and NPCs have the default "production" attribute and can engage in any production work.

But conventional military units cannot help.

That is to say, in this case, only Da Fei, Buffett, and Luo'er and Narsia who have the "Production" skill can help, and the other 10 elite Seraphs in the angel summoning space cannot help. And from this Mage Tower

Judging from the architectural style, it would take quite a while to dig from the top of the tower to the door.

Xiaoli made a prompt decision and immediately used the blood eagle's "like I'm here" characteristic to summon Buffett, who was killing monsters not far away, and Luo'er and Narsia, who were reading books underground, to dig up the sand with all their strength.

Five minutes passed, and the top part of the tower was completely exposed in the big sand pit.

Ten minutes passed, and the tower body under the spire was exposed from the deep pit, but there was no sign of doors or windows.

Xiaoli was anxious. According to this progress, the scene would be refreshed before the door could be dug out. This building would most likely be "submerged in the dust of history" and disappear. Even if it existed, she had worked so hard to dig it out.

Half a day's worth of sand is wasted!

Xiaoli immediately realized that this is how difficult it is to enter this hidden building! It is neither a powerful guard wave nor a profound riddle, but the speed of digging sand! This is simply hard to accept and makes people smile bitterly and speechlessly! Is it necessary?

Find things like tools or even an excavator in the city?

Logically speaking, excavators should be a specialty of the Seven Cities Alliance, right? Such a large ruined city of Koros is full of mysterious rooms and machines, so there must be something like an excavator, right?

While Xiaoli was concentrating on thinking, Buffett became impatient: "Friend, we don't have time! Why don't I blow it up?"

Explode!? Xiaoli immediately thought of the crystal that her elder brother regarded as a nuclear bomb, so she took out a crystal and asked: "You mean, use this to explode?"

Buffett snorted: "Whatever! This is much more convenient than being a groundhog!"

That's right, anyway, the elder brother has 8 nuclear bomb crystals, so there's nothing wrong with using one to try the effect, right? Xiaoli decided to use the smallest one. This one was dropped from the first boss that the elder brother destroyed.

Crystal, because the time energy has been used twice in a row, the quality of this crystal is slightly worse than other crystals. But no matter how bad it is, it is at least equivalent to the equivalent of 200 units of ordinary crystals. This power is equivalent to the release of 3 units of ordinary Seraph crystals.

It’s 70 times more powerful than a rocket! I can’t believe how powerful it is!

So Xiaoli equipped this crystal in the ammunition slot of the Seraph with the strongest attribute, and then the whole team stayed away from the sand pit.

Outside the ultimate range of Seraph rockets, Xiaoli aimed at the big pit and fired decisively!

Seraph's whole body flashed with black light, and a cyclone of black light shot up into the sky and spread to the surrounding area. The entire team was shrouded in black smoke and unable to see anything in the undulating and twisted space!

Xiaoli was shocked on the spot! Xiaoli has been operating in the City of God's Punishment for so long. Of course, she has seen the gorgeous light and shadow effects when ordinary Seraphs launch rockets, but she never expected that this launch would be such a big battle. This should

How powerful!

Finally, after a full three or four seconds of preheating, a black crystal flame dragged out black lightning and broke through the fog. It rumbled and exploded, distorting the surrounding air and drawing a line in the air connecting the sky and the earth.

There was an arc of lightning, and then it crashed down like a meteor!

Xiaoli’s pupils were frozen instantly!

Boom! There was a loud sound of the earth shattering, and a black shock wave mixed with yellow sand rushed towards the ruins! Under the strong wind pressure, Xiaoli's entire army was pushed back more than ten steps!

This is the power of the nuclear bomb crystal. One angel is equivalent to 70 ordinary angels! Xiaoli couldn't help but scream with excitement! At this moment, the system prompted a ding-dong sound:

System prompt: Congratulations! One of your elite Seraph Troopers, "Alesta", has undergone intense combat baptism and has been successfully promoted and evolved into a leader-level Void Seraph! Attack 20, Defense 30, Damage 10, Life

1000, mana 300, get new special skill, void killer. Intermediate void perception is promoted to advanced void perception!

Void Killer: Void Seraph takes -20% damage from void creatures and increases damage to void creatures by 15%.

"Wow!" At this moment, Xiaoli finally couldn't help but exclaimed! After releasing a nuclear bomb, she was promoted to a leader-level angel. The speed of this promotion was unimaginable, and the price/performance ratio of this crystal was simply not too high!

At this moment, Xiaofang's confused voice came from the bedroom: "Wife?"

Only then did Xiaoli come back to her senses and hurriedly smiled and said: "It's nothing, nothing, just keep sleeping!"

The next moment, the sand and dust dispersed. From the perspective of the high-altitude blood eagle, in a large sand pit like a football field, a section of a mage tower several stories high was thrust into the ground like a giant spear!

Finally appeared!

This was the result of using expensive nuclear bomb crystals. There was no room for waste! Xiaoli hurriedly controlled the Dafei and rushed towards the sand pit at the highest sprint speed.

As I got closer, I could see clearly that there were seven floors of doors and windows from top to bottom in the Mage Tower. Of course Xiaoli was flying downhill and rushing into the door at the bottom!

System prompt: Congratulations! You have discovered the abandoned facility "Kolos Void Star Tower"! The void star instrument "Eternal Mirror" is on the 7th floor of the Star Tower. When you activate the charging switch on each floor, it will be "

"Eternal Mirror" increases the power, turning on all the switches will get the maximum power!

Note: The Eternal Mirror is not affected by fluctuations in time and space. When the Eternal Mirror is activated, the scene in a different space can be observed.

Mirror of Eternity!? Without thinking too much, Xiaoli entered the door. The scene changed, and a rotunda laboratory appeared in front of her. In the middle of the hall was a magic circle, and the eye-catching golden handle next to the magic circle was obviously the so-called charging switch.

.

Xiaoli turned on the switch, and there was a buzzing sound in the entire hall, and then the magic circle burst into dazzling light.

System prompt: The first level of charging is enabled, and you get 1000 points of charging energy. You can enter the second level through the one-way teleportation array!

One-way teleportation array? Xiaoli suddenly realized it. That is to say, if she digs out a door from the ground by the primitive digging method, she will directly reach the top of the Star Building, but she will miss the full space of the six floors below.

Okay, this is the advantage of using nuclear bombs to open the way!

Then there is nothing to say. Xiaoli passed all the levels and climbed to the sixth floor. Each floor gained 1,000 points of energy. Finally, she reached the topmost star building. At this time, the scene changed again. In a glass hall, there was a person as tall as one person.

The gleaming golden "astronomical telescope" has a starry sky on the glass ceiling, and the scenery around the glass hall is the yellow sand of the ruins of Koros.

Xiaoli came to this telescope with excitement, the artifact, the Mirror of Eternity, which inspired people. It was a telescope that could view the past, present, and future, and draw a map of what it saw. The usage requirements: 1 point of wisdom.

An artifact that requires wisdom to use! Can this telescope be taken away? Xiaoli activated the last switch next to the telescope, and the entire hall was filled with golden light!

System prompt: You have activated the artifact astrological instrument "Eternal Mirror". Before the energy is used up, the Eternal Mirror and the tower where it is located will not be disturbed by time fluctuations. You can turn off the switch to save energy. There is currently 6999/7000 energy left.

!

That’s it! That is to say, as long as this artifact is turned on, the star building will not change with the scene refresh! This is so convenient. So, how to use this telescope?

Xiaoli stretched her eyes towards the lens and looked at the starry sky on the ceiling from the angle of the telescope. The scene in front of her eyes changed. A magnificent palace appeared in her field of vision. Countless level 7 Titans from the City of Mage were patrolling around the palace!

Xiao Li was horrified, this is the void where the Titan Lord is located as mentioned by her elder brother? In other words, with this telescope, the opponent's movements and layout can be clearly understood!
Chapter completed!
