“He is Tom's friend. They had known each other before Tom joined the FBI, and Lucas visited here yesterday.（是汤姆的朋友，在汤姆进入FBI之前就认识了，昨天来的。）”另一个FBI成员说道。
“Oh, okay, I just hope he will not cause any trouble.（哦，好吧，但愿别捣乱了。）”那个FBI成员点了点头。
“Hey, wait, kid, you shouldn't mix reagents casually!（哎，等一下，小孩，不可以随便混试剂！）”话音刚落，一个FBI成员忽然看向了做实验的卢卡斯。
谁料，卢卡斯一惊，不慎将烧杯打翻，卢卡斯立马后退避开！
“Lucas, be careful!（卢卡斯，小心！）”这时，汤姆恰好进来，看到眼前的一幕，立马径直上前，一把抱过了卢卡斯，接着说道，“What should you do if the chemical solution comes into contact with your skin? Be careful of the corrosion!（药水碰到身体怎么办，当心腐蚀！）”
“OK, I’ll be careful!（好，我会小心的！）”听到这儿，卢卡斯倒吸一口凉气，一打汤姆的手臂，立马回答道。
只见，那块打落的石头在桌上发出了一阵亮光……
不久，室外射击训练营内，所有FBI成员们练着枪。
“Jackson, your shooting is really accurate!（杰克逊，你的枪法很准。）”凯瑟琳路过，递给了楚浩然一瓶饮料，“Here you are, the FBI Energy-Boosting Electrolyte Drink.（给，FBI补充能量的电解质饮料。）”
“Oh, okay, thank you!（哦，好，谢谢。）”楚浩然接过了那瓶饮料，深饮一口，接着举起了手臂上套着的一个机械装置，问道，“Catherine, I want to know what’s this and why should I wear it?（凯瑟琳，我想知道这是什么，为什么要戴着？）”
“This is a device used by FBI members to monitor their physical condition, simply turn on the switch, and all your health metrics will be displayed as a holographic image. And you can check it at any time.（这是FBI成员用来看自己身体机能的装置，点一下开关，所有你的身体状况都会以全息影像的样子显现出来，你可以随时查看。）”说着，凯瑟琳点了一下楚浩然手臂上的机械装置。
只见，一个全息对话框浮现在眼前，所有的感应指标都显现了出来！
“It is really surprising! Well, it's really three hundred years later after all!（那么惊人吗，不亏是三百年后！）”看到这儿，楚浩然顿时大惊。
“You can also adjust the button, and it shows your weapon status.（还可以调一下按钮，这是你的武器状况。）”说着，凯瑟琳又按了一个机械装置上的按钮。
只见，那个全息对话框一闪，浮现了楚浩然武器的子弹数量、良好程度、使用寿命……
“I will use this mechanical device properly, Catherine.（我会好好用这个机械装置，凯瑟琳。）”楚浩然关闭了那个机械装置的按钮，全息对话框顿时消失。
“Tom, why do you miss a bullet?（汤姆，你的子弹怎么会少了一颗！）”这时，耳边传来了一个FBI成员的喊声。
“Oh, sorry, I probably accidentally lost it...（哦，我很抱歉，大概是不小心弄丢了……）”汤姆顿时无奈。
“No more times like this, Tom!（不许再有下一次，汤姆！）”那个FBI成员一推汤姆，喝道。
“What’s wrong?（怎么回事？）”楚浩然看向了凯瑟琳，有些惊讶。
“It's Tom again!（又是汤姆。）”凯瑟琳一手扶着楚浩然的肩膀，无奈至极。
半小时后，所有人停下了练枪，来到了休息区。
“Tom, did you miss a bullet?（汤姆，你的子弹是不是掉了一粒啊？）”这时，卢卡斯忽然出现，来到了休息区的汤姆身边，递过了一颗子弹。
“Lucas!（卢卡斯！）”汤姆一惊，立马抱过了卢卡斯。
“Hey, Tom, just loose me for a moment!（哎哎哎，汤姆，先放开！）”只见，卢卡斯推开了汤姆，汤姆松开手，卢卡斯在汤姆耳边用手掩着嘴，轻声说道，“Let's go to the place where you gather medicinal herbs, and I want to see if I can repair my UFO.（和我去一趟你采药的地方，我要试一下可不可以修复我的UFO。）”
“Now? I still have to practice shooting in a bit, for now, we’re just resting.（现在吗？我一会儿还要练枪，现在只不过是在休息。）”汤姆一愣，开口道。
“Well, let's go in a moment.（那一会儿去吧。）”卢卡斯一拍汤姆的肩膀，说道。
“Oh, well, was that the black stone you were examining this morning? Could it be that there wasn't enough of the stone?（哦，对了，是你早上研究的那块黑色的石头吗？是不是石头的量不够啊？）”汤姆忽然想到了什么，于是问道。
“It's not the stone, it's the heavy dark iron I brought from Mars.（那个不是石头，是我从火星带来的重金玄铁！）”卢卡斯看向了汤姆，开口道。
“OK, maybe you brought too little?（好吧，是不是你带的太少了啊？）”汤姆开口道。
“I don't know. When can I return like this?（我也不知道，像这样，我要什么时候才可以回去啊？）”卢卡斯低下了头，很是失落。
“All right, Lucas, there's always a way.（好了，卢卡斯，会有办法的。）”只见，汤姆摸了摸卢卡斯的头，接着说道，“After all, the heavy dark iron is hard to get, just treat it as you were on a trip to Earth!（毕竟玄铁难求啊，你就当是来地球旅游来的吧。）”
“OK, I'll check next time whether there are any resources of the heavy dark iron on Earth.（那好吧，我下次看看地球上有没有重金玄铁的资源吧。）”卢卡斯无奈，开口道。
