On the top floor of the main house of the Jiraman family, in Li Lin’s studio.
Mrs. Karina had specially equipped him with a workshop, but the studio still belonged to him.
Therefore, Li Lin completely separated out the overlapping parts of the studio and workshop functions.
The studio is where he conceives and designs new drawings, while the workshop is where he makes new technological devices.
After turning on the chandelier in the room, Li Lin took Caitlin to the innermost room, opened the safe in the corner, and took out a very heavy Hextech treasure chest.
Then he used a Hextech key that matched the unique mechanical lock core to open the treasure chest and took out more than ten drawings.
Caitlin randomly pulled out a diagram from Li Lin's hand and asked, "What kind of diagrams are these?"
Since she was not interested in Hextech inventions, she looked down for a long time but couldn't figure out what it was.
Li Lin took the drawing from her hand, took a look at it, and couldn't help laughing.
"why are you laughing?"
Caitlin was a little dissatisfied, thinking he was mocking her. She snorted and said, "I haven't learned any mechanical theory, so isn't it normal that I can't understand it?"
"You misunderstood me."
Li Lin shook his head and waved the drawing in his hand at her.
"I don't really understand this thing yet. It's just a concept. It's normal that you don't understand it."
This is an artificial satellite, a communications type.
However, before traveling through time, Li Lin didn't pay much attention to these things that he didn't encounter in daily life.
After traveling through time, Piltover and Zaun did not have such relevant technology, so he just came up with a rough idea based on his common sense.
Even if it can be perfected, it depends on whether the system can produce this technology in the future.
Afterwards, Li Lin handed her another drawing with all the data clearly marked.
"Look at this one."
Caitlin took it and looked at it doubtfully, her eyebrows raised. "A radio walkie-talkie...can it achieve wireless communication within a short distance?"
Then, she suddenly looked up, her pupils full of shock. "Wireless call? You developed an advanced version of the landline phone so quickly?"
“Not really.”
Li Lin sighed as he thought of the smartphones that people on Earth had come to rely on in their daily lives before he traveled through time.
"Compared to the final effect I want, it's still far from it...but it's something that will be indispensable in the future."
He took the blueprint from Caitlin and said, "Let's go. We've wasted quite a bit of time. Lady Karina might already be waiting for us..."
Caitlin, who was about to ask about the radio, suddenly changed her expression and said, "Yeah, I almost forgot about that!"
…
…
A few minutes later, the two went downstairs to the second floor and looked at the reception room on the first floor from the handrail in the corridor.
As expected, Mrs. Karina was already sitting on the sofa, pouring herself a cup of tea.
As if she heard some noise upstairs, she didn't even turn around and asked in a cold voice, "What are you two still doing standing there?"
Caitlin's face changed slightly, and her heart was beating fast.
She exchanged a glance with Li Lin who had turned around, and her nervous heart finally relaxed a little when he mouthed "Don't worry, I'm here."
Afterwards, with Li Lin leading the way, Caitlin followed closely behind him. The two walked down the stairs one after the other and came to the opposite side of Kalina.
From beginning to end, Kalina never looked up at them, her eyes fixed on the steaming Hextech kettle on the table.
Apart from the bubbling of boiling water in the kettle, there was no other sound in the room.
The atmosphere in the reception room was suddenly extremely depressing.
Caitlin, who had relaxed a little after being comforted by Li Lin, became nervous again.
Even Li Lin couldn't help but feel his throat moving when facing this situation and his "mother-in-law", and he also felt a little nervous.
After a long while, Kalina's blue eyes turned upwards, lightly swept over the two of them, and her gaze briefly lingered on the drawing in Li Lin's hand.
"Just sit down, why are you standing?"
Hearing this, Caitlin quickly sat up straight on the sofa, still with her head lowered, looking like she had done something wrong and was caught by her parents.
Li Lin stared at the pressure that Karina was exerting intentionally or unintentionally, sat next to Caitlin, and even boldly grabbed her little hand and interlocked their fingers.
The girl was startled and quickly looked up at her mother sitting opposite her without making any noise. She found that her attention was not here and she tried to break free from Li Lin's hands.
However, she was afraid that her little action would be discovered by her mother, so she didn't dare to use too much strength and was unable to pull her hand out.
Caitlin raised her head and glared at Li Lin beside her, but he gave her a reassuring look in return.
Helplessly, she could only lower her eyes again in worry, as if she had given up on herself. Her little face was almost buried in her chest, and she didn't dare to observe her mother's expression at all.
Mrs. Karina naturally noticed Li Lin's actions.
But she just glanced at him indifferently, raised the tea expressionlessly, blew away the hot air, took a sip, and said nothing.
The atmosphere in the living room fell into dejection again.
A few more minutes passed, and with the creaking sound of the door leading to the corridor, the tormenting atmosphere for Caitlin was broken.
"Oh, damn it! That old bastard Kevold really disgusted me. I finally sent him away..."
Elro, his face slightly flushed, opened the door and walked in cursing.
