Dragon Ball chapter 355, pg 441:

"WHAT?! They even knew about the SENZU?!"

Piccolo was aghast at the fact that the cyborgs had beaten them and that they already knew about some information.

"Why didn't they finish us off?" Tenshinhan replied

"Probably they didn't feel like that we were worth killing. They couldn't care less if we're dead or alive."

"I wonder little. They're incredibly strong… Too strong… I never really imagined this!"

On the corner next to Kuririn Vegeta was fuming over not just losing to a cyborg, but a girl. He was also making "Grrrrr…"ing noises.

Trunks tried talking to him saying, "Dad, you don't…"

"FFFFFFFUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU…"

And Vegeta shot into the distance.

"DA…!"

"STOP! DON'T GO AFTER HIM! YOU'LL ONLY ANGER HIM MORE!"

"But…!"

"Besides," Piccolo continued, "he finally recovered his long-wounded arrogance when he became Super Saiyan and then he got his insides kicked out by a woman. Or at least a cyborg that looks like one. He won't be in the best mood."

There was guilt on Kuririn's face, "I…I'm sorry…I got scared and couldn't face them."

Ten spoke, "Forget about it, Trunks was a Super Saiyan and he felled in one blow. I wouldn't have made a difference anyway."

"This is the being who killed Frieza…" Ten thought, "and even he was powerless against the cyborgs."

"We've got to face facts! Goku is powerful but he's not so different from Trunks or Vegeta! WE CAN'T WIN! Not even with Goku."

"They were a…a little different from the cyborgs I knew. They weren't…that strong…I…I could put up a decent fight by myself."

"Piccolo…Piccolo…"

"Kami?" Piccolo thought

"Yes, it's me, and unfortunately I need to give some urgent news."

"I can guess that you'd rather not let the others know to create a shock."

"MMnn, well what I need to say is that while you and the others were fighting, I had a precognition, a rather unclear one but still…"

Piccolo was a little nervous, what was so urgent about this precognition that needed to be said?

"What… did… you see?"

"I could only make out on one thing, and it was grim."

"Spit it out already!"

"I saw a monster far more powerful than the cyborgs killing Gohan's mother in front of his eyes."

Piccolo was in total shock at this,

What kind of monster is this?! Does it mean that Goku's family is in danger?!

"What's wrong?" Kuririn asked, "You were speaking Namekian and that's no sunny expression on your face."

"It's nothing."

Kuririn made a confused look.

"If you don't mind, could you oblige to allow me to bring Goku and at least his family to the Temple?"

"Alright…"

"Kuririn, could I borrow a plane capsule?"

"Sure," said Kuririn giving the capsule to Piccolo, "Although why do you need it?"

"I can't tell you exactly why but just remember to regroup back on the Temple, see you then."

Piccolo then levitated and started flying to Goku's house.

When Piccolo arrived he knocked on the door.

ChiChi then came out, "IS THAT YOU GO-... PICCOLO?!"

"Get on the plane, we're going to the temple."

ChiChi in bewilderment looked Piccolo to see a plane set up.

"Why?"

"Huh? Who are you…? Piccolo?"

"Yes?"

"Good news, Goku took the medicine and is just sleeping now, He's going to be fine!"

"Good to hear, but LET'S STOP YAKKING AND GET ON THE PLANE ALREADY! EVEN GOKU!"

The three then went to work to get all of the necessary luggage and passenger onto the plane.

As they were flying Yamucha who was piloting asked, "Why are you acting so urgent? Did something happen when you fought the cyborgs?"

Piccolo didn't answer but just quietly meditated.

"Alright, suit yourself and leave us all in the dark."

"ChiChi getting killed?" Piccolo thought, "They would all be in shock if I told them, and what exactly is this monster? Perhaps I can attempt to prevent that if I can figure out where this monster of such exists now."

Tap…Tap…

"Hey, can you let us in?"

Piccolo opened his eyes to see Trunks and Gohan flying beside the plane and the others staring back.

"Open the hatch door."

"Right away," Yamucha replied

As soon as they came in Trunks asked, "Why did you fly off like that with no reason?"

"I thought I said to meet at the look out."

"I was worried so I followed your ki here, Gohan just joined along…"

"So," Yamucha interrupted, "What happened with the cyborgs?"

"I told Gohan the details, we were obliviated, the cyborgs were much stronger than the ones that I faced. And they are simply treating killing Goku like it is just some game."

"…What are we going to do?"

"Maybe I can go further into the past with the time machine and destroy them before they are activated?"

"You sure that will work?" Piccolo asked, "From what I'm told the time machine takes a long time to charge up for a trip and back so you'd be stuck for a time…"

"And also…" Gohan interrupted, "what's going to happen to the cyborgs in the present? Are they going to disappear?"

"That's right!" Trunks replied, "the future of that timeline would be saved but there wouldn't be any change in this timeline where the cyborgs exist!"

"I see that someone is using their brain."

"Well that basically applies to my timeline as well, even though Goku is going to live in this timeline, Goku will still be dead in mine, but my Mom wanted to at least create a peaceful future where they were destroyed. Although there are some differences, like the timing of Goku's illness, and there are two cyborgs and one android, and there're far stronger."

"But why is it different?" Gohan asked

"I'm not sure. Is because I used the time machine before?"

"Don't worry yourself about it." Chi-Chi said, "Goku would've died if you hadn't come! I'm thankful for that! It'll work out for the best, I'm sure!"

She then continued on to chuckle.

"How could you laugh when you may or may not die in the near future?" Piccolo thought, "I mean the cyborgs and now this monster. I can only hope for the vision to not come true in the end."
