After fighting for several days, Lin Tian only rested for two or three hours a day, and was already very tired.

However, you can't sleep much. Lin Tian knew that this metal fortress can only exert combat effectiveness by using the dual mechanical super-body skills.

Now the number and strength of monsters and demons outside the metal fortress are constantly increasing.

Once you sleep too much, the metal fortress will be breached by monsters and demons, and people in the city will be slaughtered.

If you sleep more every day, the speed of casualties and injuries of the guards in the camp will increase rapidly when you sleep.

Lin Tian raised his hand and rubbed his eyes, sighed, and began to pick up his mobile phone to type, and communicate with the Earth Special Command.

[Liu Jiao, you probably think how long will the monster and the devil siege last? I can't stand it anymore!]

Lin Tian sent a message.

Underground of the Earth Alliance Building, many analysts in the special command center also frowned and analyzed.

According to the number of monsters outside the metal fortress transmitted back by the super phone, as well as the number of monsters and demons casualties in the past few days.

In fact, the monsters that besieged the Metal Fortress have not decreased, but have also increased.

[Lin Tian, ​​the only way to fight back or destroy these monsters and demons is to upgrade the special laboratory skills after you reach the second turn and then have hope. You still need to continue to control the metal fortress to fight. If you continue to fight for about two or three days, you can upgrade.] Liu Jiao's voice appeared in Lin Tian's Bluetooth headset.

After hearing this reply, Lin Tian smiled bitterly.

He stood up slowly, got up from the control chair and moved, and opened his eyes to look at the metal tower control room.

I have to continue to control the metal fortress for two or three days, it’s too long.

Lin Tian walked to the top of the command tower and stood on the top of the tower and looked outside.

Outside the Metal Fortress, many monsters with different appearances and demons were running towards the Metal Fortress, and a new round of attack was about to begin.

The monsters here are too persistent and have died so many times, but they still don’t give up.

Lin Tianyi gritted his teeth and decided to be fierce. He insisted on high-intensity command and fight for two or three days. Humph, then all these monsters and demons would be killed.

Time keeps passing, monsters and demons continue to siege the city.

After a long battle, casualties also occurred in the Demon Curse Fortress.

On the morning of April 16, Lin Tian finally received a prompt, and he upgraded to level 1 lv60 and could perform a second transfer.

Lin Tian immediately called Reina, "My experience has met the requirements of the second transfer. Are there any transfer items or options for the second transfer?" Lin Tian asked Reina, the mechanic.

"Congratulations to the leader!" Reina said first. "If you transfer the second time, you can directly conduct the same job transfer as the first time, so that you don't need to transfer the job transfer items. It's just like you want to transfer to other job titles."

After hearing this, Lin Tian thought about it. The mechanical overlord profession he brought with him is very good now. He will continue to choose the second transfer of the mechanical overlord profession, so he won't change it.

Lin Tian’s Bluetooth headset sounded Liu Jiao’s voice from the special command of the Earth, [Lin Tian, ​​change jobs as soon as possible. A teleportation channel opened by demons appeared on the surface of the moon in our main world. According to the astronomical telescope, the demon army gathered in space and was about to attack the earth. It is best for you to solve the demon army on the God and Demon Continent to support the earth.]
