Kai and BC slid down the slide into the lab. ‘I’m going to open the battle chamber,’ said Kai.

The battle chamber was hidden behind the lab wall. Kai took out his Border Guard Card. He put the card into the lab computer.

Then there was a loud noise.

 

Kai watched as the bricks in the wall behind them began to move. They made a hole in the wall big enough for Kai to climb through.

Kai and BC climbed into the battle chamber. ‘We are going to the wind land, BC,’ said Kai.

‘We need to battle wind with wind,’ said BC.

‘Yes,’ said Kai.

Kai looked at the gear on the battle chamber walls.

‘I think I will pick the T-F-1000. It has three blasters. The Gear Mash-Up will change them. It will make them work for a wind land I think. Three blasters is better than one.’

Kai put the T-F-1000 into the first chamber.

‘What will you pick next?’ asked BC.

‘I’ll need to fly,’ said Kai. ‘I’m going to pick the Astro Jet-Striker. It was handy in the wind land last time.’

Kai took the Astro Jet-Striker from the wall. He put it into the first chamber with the T-F-1000. Then he closed the door and waited.

Soon the computer screen flashed.

Kai opened the other chamber.

‘Look at this, BC,’ said Kai. ‘It has two wind blasters and some sort of zapper blaster.’

‘And the jet pack looks lighter and better,’ said BC.

‘Yes,’ said Kai. ‘I think we chose well. Now we need to get our ride ready.’

‘Time to go to the transport chamber,’ said BC.

‘That’s right,’ said Kai. He grabbed the T-J-Striker. Then he and BC took the slide to the transport chamber.
