Lu Huang and Luo Fei were so shocked.

Of course, Tang said it to them on purpose!

He knew very well that the instructions he had made now were just the simplest version of the compass.

But what he wants is an "automatic wayfinding system" that is included in any game!

With his own entry-level casting technology and a little understanding of materials, it is impossible to achieve the promotion of this technology!

Sure enough, Luo Fei was immediately attracted by a strong interest in research: "Can you...you...sell me the design drawings? No, no, this requirement is too much...can you let me participate in the pointing star needle......"

"Continue to research and development?" Tang Zheng narrowed his eyes and helped him complete the wording.

"Yeah, yeah!" Luo Fei nodded three times, "If this pointing star needle can not only point to the main star, but also the auxiliary star..."

Because the different astrological talents of the Star-Looking Luo family can only feel the power of different shattered stones from all over the world. The talent gives only one range. After reaching the general range, they can only rely on experience to find them on foot.

Tang Zheng's pointing star needle just complements the Luo family's astrological talents!

Of course, the first thing to solve is the paradox problem of "what star power is needed to activate it" - all the auxiliary stars have been broken, and there is no one in the Xingyao Continent, so it is impossible for the auxiliary stars to be able to lead the auxiliary stars into the life palace.

Tang Zhengyixiao: "Okay, but I have a condition..."
