The Saiyans loved Earth food. Especially sweets and cakes, unknown to Saiyan cuisine, so Chichi had her hands full. They got used to life on the ship, however Gine spent a lot of time in the medical ward supervising Vegeta's health. He was slowly getting better.
Bulma had a different worry. The photon system was running low on fuel. The force shield they had to use at the takeoff from the planet, the gravitron stimulator, as well as several days of energy required for the healing pod were taking its toll on the energy supply. They would have to change the power modules soon, and changing them meant switching practically everything off, including the healing pod. In normal circumstances she would do the change on the ground, having lots of time, technicians and full gravity and air supply. Turning everything off gave a short time gap for the change, they ship itself contained safe oxygen level for less than six hours. They would have to turn off the gravitron, so instead of walking they would be floating. The last change of fuel took over twenty hours. The fuel tanks weighted each around a tone, and four had to be installed to give the ship enough energy to fly to Namek. Fortunately they had several Saiyans, so the weight of the full tanks could be carried by them. Gohan was small enough to go with her into the fuel pipe to manually program the tanks. After considering all the factors she decide it might actually work, so the last two days she spend preparing. She gave Gohan some papers with information he should know before trying to program the tanks. She test ran the support engine so that they wouldn't go off course, and managed to get it working to recuperate the oxygen in the ship, and keep basic life support and lights. She made sure she had enough fuel tanks, so that once they get to work they would be able to get all four in. She explained to the Saiyans what needed to be done, and what was their role in the whole deal. Gravity would be turned off so they had to manage four very heavy but delicate containers. The lack of gravity would make moving them easy, however they couldn't just float around, if the hit anything they would explode.
The last step was what to do with Vegeta. His life support system would be one of the first turned off, his state was improving but it was far from perfect. Some injures had already healed, while others were still in the process of healing. Bulma decided to drain the fluid, give him on oxygen mask. Gine would stay with him in the infirmary to monitor his condition. If everything went as planned the machine would be working as soon as the fuel tanks were secured.
Chichi got the role of monitoring the main computer in the control room. She had to observe oxygen level, and she got strict instructions what to do when the system would start working again.
The next day the ship started showing first sign of lack of fuel. They lights would go on and off, the healing pod communicated insufficient power level. The computer kept sending messages about the time left for the fuel tanks to go empty. When the computer said it was the last five minutes, they all went to their spots. Bulma quickly decapsualized the four fuel tanks, and the Saiyan men held tightly so they wouldn't float around with gravity. When the computer did the last countdown Bulma and Gohan were at the entrance to the fuel pipe.
"Remember as soon as we go in, we take the old ones out, you bring them out here. The red one has to go first, then blue, then red again and blue last." Bulma kept explaining to the child.
"Got it!" Gohan confirmed.
"We're in!" Bulma told him, as soon as the gravity stopped working, both swam into the pipe.
"Turn it left, then push the security button and gently pull out, they are empty so they won't weight a lot." Bulma instructed as the child attempted to pull the first pipe shaped tank out. "Slowly there might be a drop or two left, and they are still dangerous." Together they pulled the first tank out, Gohan securely passed it on to Nappa waiting at the entrance to the fuel pipe. They had to repeat the same manoeuvre three more times, which took over two hours.
"Gohan blue goes first." Bulma reminded him as the child flew towards the entrance for their first pipe. "Be careful it's very heavy."
"I can feel that." The child slowly moved inside with a new pipe. It was glowing a vibrant blue, the liquid inside moving constantly. "Now put it in the first hole." Bulma instructed. "Turn left until you hear and click." They both moved the handle on the top right, securing the first pipe. Bulma entered the validation code, and after a moment they heard Chichi yell "We got the first one!" To get all four pipes in took four more hours, the progress slow, but it had to be done slowly due to the risk.
After they got out from the pipe Bulma and Gohan saw a strange sight at the door. Gine was standing there holding a severely injured but conscious Vegeta, who looked pissed as hell.
"Nappa, Bardock were they hell AM I!" He yelled at the two soldiers.
"In hell your highness!" Bulma smirked at him. "Now move your stupid Saiyan ass back to the infirmary I need to get my ship working."
"How dare you!" Vegeta yelled at her. "You're just a lowly slave!" He reminded her.
"A lowly slave with a state of the art ship. No thanks to you. So just shut up and let me do my work." Bulma replied.
Raditz, Nappa and Bardock just watched dumb folded as the small human female spoke to their King.
"Computer check the positioning of the fuel pipes." Bulma ordered the computer. "Fuel pipes in place." The computer replied. "Computer test run all four pipes." "Test running, test completed, pipes in prime condition."
"Time to strap in, before we launch this baby again." She didn't have to say that twice to the Saiyans, they remembered how rocky the last start was. Only Vegeta tried protesting, but Gine firmly told him to shut up and forcefully dragged him to the control room, and with the help of Nappa strapped Vegeta in one of the chairs.
Vegeta looked with astonishment at his slave. She was sitting in the main chair, tapping like crazy into a keyboard. When he awoke, he found himself on a strange ship. His whole body hurt, as if he had almost every bone broken. He remembered his last fight with that irritating Brolly, and later nothing. He actually thought he had died. Now she was running the ship as if it had been hers. She was ordering his men around, and even Nappa listened to her.
"Computer ignite photon system." She told the machine.
"Photon system ignited." The computer confirmed.
"Set the coordinated for data .1." "Confirmed."
"Retrieve last photon calculation." "Confirmed."
"Calculate fuel level and estimated time of arrival." "Calculating, fuel level at 99%. Time of arrival 4 days and twelve hours."
"Computer set the gravity system for inertia." "Confirmed."
"Here goes nothing..." She murmur under her nose. "Computer activate photon system!"
The sudden pull made everyone gasp, the view blurred as they entered hyperspace again.
