　　FYI, the missing 2 chapters of vol.16 worth more than 12.000 words of Hanzi, so please understand, i will translated only Ziyan’s part. because next chapter Ziyan’s part is coming. the other story i probably translate after this vol.17 end. Thanks….

　　As expected, when he returned to the residence and entered the independent small courtyard where he temporarily stayed, Rong Tian had been waiting in the inner room.

　　He seems to have just bathed, wearing a simple robe and also expose a little chest muscles of his neckline, showing his strong body, s.e.xy and charming.

　　Feng Ming enters the door and enjoy what he sees, he happily run over. “Guess what we did today?”

　　Rong Tian laughs. “What else can you do other than playing?”

　　He holds Feng Ming on his lap and helps him slowly ma.s.sage his tired calves.

　　Feng Ming comfortably ‘hummed’ twice and whisperly praise. “Rong Tian, if you’re not suitable to be a king, you can at least open a ma.s.sage parlor to be a boss or something.” Turning around, he holds Rong Tian’s neck, and says “We don’t just go out to play today, we do a lot of things, firstly…”

　　“I first went to the Foundry to meet Hong Yu and then went to the fleet, Lie Zhong s.h.i.+ and friends also brought the wooden box back.” Rong Tian interfaced, “I know it all, and you don’t want to think about who brought it back.”

　　Feng Ming also think about it, Rong Hu returned earlier than they did, of course when they met he will report their every move to Rong Tian.

　　“What is a trebuchet?”

　　“Uh?”

　　Rong tian can’t help but knock on his head. “The trebuchet, the one you almost said to Hong Yu today.”

　　“Oh! That?”

　　Feng Ming grimaces. “Rong Hu's sense of smell is really sensitive, he actually came back to tell you about the trebuchet ah? Hehe, How could I have never thought that maybe this thing would help you a lot? The trebuchet is a weapon that is launched using the principle of leverage, you can throw a heavy boulders or sh.e.l.ls into the enemy arrays.”

　　He finds a pen and paper and draw a few times.

　　His knowledge of the trebuchet was limited to watching ancient war films on television, especially when the ancient Romans fought, they used it when they attacked the city. Hundreds of trebuchets were launched together, and the wall suddenly collapsed. It was a wonderful and impressive scene.

　　But exactly how it was made, Feng Ming is not clear.

　　Fortunately this thing should be very simple, to put it bluntly it’s a large seesaw.

　　Feng Ming has one of the most advantages over the ancient people, that is the basic education of various subjects in the modern system, especially physical chemistry, when he first studied, he didn’t expected that those scientific principles that seemed to be so boring were so valuable.

　　He imagines the shape of the trebuchet in his brain, he tried to rack his brains to link this thing to the practical application that the physics teacher had said.

　　He draws it off on the paper. After changing papers and drawing again, he scratched his head and thought hard to remember how the beloved physics teacher used the various applications of leverage to draw several pages back and forth. Finally, he pointed to a similar-looking drawing and says. “I guess, it’s probably like this.”

　　Rong Tian bows his head and looks at it, the drawing is really to be less than impressed and crooked from side to side.

　　But it can be seen faintly.

　　Rong Tian frowns. “With this thing, how can a boulder be thrown out?”

　　“Because force multiplied with length is equal to force multiplied with length, this is the principle of leverage. You don’t understand, right?” Seeing Rong Tian’s warning eyes drifted over, Feng Ming hurriedly a.s.sist him with smiling face, “hihi.. Of course you don’t understand. I don’t know how to explain it in detail to you, anyway you can say that, this thing can take advantage of the increase in distance, so that the force thrown at the opposite place will increase, ok? Do you understand? Alas, if this question had been explained to Third Princess, she would have immediately understood that, she really has a good research on physics mathematics. Regarding the leverage, when I was in Fan Jia, I still…”

　　Feng Ming’s voice suddenly stuck.

　　Rong Tian sees his face change strangely and asks, “What’s wrong?”

　　“Uh, if I were to tell you, I seem to have discussed this principle with Ruoyan, will you be angry with me?” Feng Ming asks with a worried look. “I didn’t know anything about it that year, i don't know if this kind of thing is a state secret, at that time, you also tricked me to go to Fan Jia…”

　　Rong Tian gently points a finger on his lips and smiles lightly. “Why am I angry? You are so smart, that you can shocked Ruo Yan, I’m glad even it’s too late.”
