When Tsuna heard this without knowing why his soul seems to shudder as he wondered in his mind 'Why happened when I heard about that truck shaped divine object which seems from ??? known as Truck-kun, does it actually have to do with the memories of ??? and the system I obtained since according to what Reborn said that most systems are sometimes just randomly obtained in either an accident or given by a god, but in my case, I just obtained it when I came home.' But when Tsuna thought of this, he decides to shrug this feeling off for now and decided to focus on more on what Reborn was saying.
Then as Tsuna just thought this Reborn had continued talking about the people who were theorized to be reincarnated, according to what Reborn said some of the people who were reincarnated was part of some factions, which were mostly from the magic faction and rarely does from other faction members get targeted by the truck shaped divine object.
Reborn also said that there where other ways for people had been sent or reincarnated to other worlds such as a god, separated from the god faction of Fushizen city. Reborn also mentioned that there are various sub-factions of each faction similar to the Magic Faction separated by either magic techniques, type of magic and fundamentally how they use magic itself.
When that gang who mostly heard this and even Hayane and Kyou who seemed to have already known about the DW Era was surprised as they both thought that the factions they heard off were united similar to their Dying Will Faction which although also have a few subgroups still in the core the same faction.
Then Reborn after finally finishing saying about the other factions and some of their sub-factions. Reborn said "Now Let's get back to the main topic as I got sidetracked for a bit there, Well returning to what I just said earlier about after the factions had just been born after 50-70 years after Humans first started to get special abilities. The largest faction in the world back then is our Dying Will Faction due to the most common ability humans had gotten back then was unlocking their dying will flames. So, in turn, our Dying Will Faction had temporarily become the strongest faction.
"But about 20-30 years after the separation of the factions. Another unknown event suddenly happened once again on our world and without knowing how or where various races that aren't humans had appeared in the world including, Gods, Elves, Dwarves, Demons, Spirits, etc. And also Aliens."
When Lambo heard he suddenly shouted as he sounded scaredly said: "Wait for Aliens like those scary monsters from movies I saw kinda like those predators!!?" When Reborn heard this, he threw a button from his suit and hit Lambo in the forehead with it.
When Lambo heard this, he started to cry. Still, he managed to not pull out the bazooka immediately as in the weeks that he had stayed with Tsuna and the others he became more confident in himself. He tried not to be as crybaby as before, but still, Lambio's core personality is a crybaby.
As Lambo said with a crying look with snot coming from his nose with also an angry look as well to Reborn "Hey, why did you hit me like that I was just asking a question." Then Reborn replied with a cold tone "I threw with at you because you were annoying and interrupting me." Due to this scary and cold answer Lambo now finally lost control of himself and started to pull out the ten-year bazooka.
But before anyone was able to stop Lambo, he shot the bazooka towards himself. Still, due to him accidentally tripping on some food that Ryohei was eating earlier, I-pin who was beside Lambo was also shot with the Bazooka and after a puff of smoke. Appeared the future Lambo that Tsuna and Chrome had encountered once before and a red hair girl wearing a white cheongsam-style shirt with red sleeve cuffs over blue shorts. Similar to I-pin current clothes but pallet swapped.
This girl also wears a hairpin on her twin-tailed braided styled hair. The Future Lambo when he sees Bianchi he almost was about to run, but luckily he remembered something and then Future Lambo brings out from his behind a helmet and immediate wears it.
Luckily due to Future Lambo's quick move, Bianchi wasn't able to have a glimpse of his face which due to this he released a sigh of breath as he said: "Oh hey everyone didn't think that I would be sent back here again, at the time when Future Boss here had sent us to a mission, so I guess we can relax for a bit since we have to wait for 5 minutes before we return anyway. And young Boss although I think you already saw who the other person which young me had brought here, but yeah I guess I'll introduce her to you guys anyway, and this girl here is Future I-pin."
Then the girl who was introduced by Future Lambo to be Future I-pin suddenly said excitedly "Ohh I'm actually here back in time like Lambo-Kun told me, Well everyone I am Future I-pin and base on why everyone is here today I think this is the time when Reborn-san told about the first DW Era right and when I first came here right... O wait I wasn't supposed to say that please forget that."
When everyone heard this, they became shocked as although even when they heard about when Lambo had exchanged places with his future self from Tsuna's story back then. However, everyone had just thought that it was just a joke except Bianchi, Shammal, Hayane and Kyou since they already knew about Lambo's family and already knew about the ten years Bazooka.
Then as everyone was about to comment on what just happened unlike before when Reborn wanted to ask Future Lambo something, now Reborn seems genuine doesn't care and continued saying.
"When these new factions first appeared in this world they firstly initially. Were hostile and attacked the humans who lived in this world. So due to this the population of various factions greatly diminished and the original humans who first lived in our world almost went extinct. The world would have become controlled by the foreign races who invaded this world."
When everyone heard this, then Tsuna said while sounding very confused "Hey Reborn didn't last time when Future Lambo came here you were very interested d in him but why are you ignoring him again this time."
Then Reborn stopped talking about the DW Era topic and finally said in a bit of an irritated tone" Because I was still pissed about the last time I confronted that adult version of that annoying cow."
