Chang Geng: "What is this? Is there something burning inside?"

Ge Pang Xiao smiled and said: "Hehe, it is Ziliujin."

Chang Geng said: "Do you not feel hot?"

Ge Pang Xiao pulled open his clothes and revealed that he had a dark board on his chest. This was used for heat protection inside a heavy armor in the area that was equipped with explosives. The boy had cut it into the shape of an undergarment*: "Iron undergarment!"

*a piece of undergarment women wear under their clothes, covering their chests.

Gu Yun took off his blindfold, put on the liuli glass, and carefully looked at Ge Pang Xiao's masterpiece, unable to help admiring it. He felt that although these children didn't know anything aside from playing around, since they insisted on going with Chang Geng to the capital at such a young age, even if they weren't ones with grand ambitions, they certainly still had their own talents.

Ge Pang Xiao used the monk's sign language: "Who said that only women can wear undergarments?"

Gu Yun gave him a thumbs up – You're completely right.

Chang Geng: "..."

On the table, the two compasses were spinning in a frenzy. Ge Pang Xiao gestured for the pair of them to look, then gently tapped the table and put up three fingers - The compasses had been messed up for at least three days.

Gu Yun often went out - he could understand it immediately at a glance.

People usually brought two compasses when traveling. If one of them would fail, the other could be used to determine whether the first compass was broken or if there was a problem with the local area. There were certain places in the desert or at sea where the compass could become ineffective, the general merchant and fishing ships would avoid them.

But this group of Dong Ying people, not only did they not evade, but they also deliberately headed towards it. The route had no doubt deviated from the initially established destination.

'Came from the ground, going to Hao Li,' what exactly did this 'Hao Li' mean?

Ge Pang Xiao: "Fortunately, I also brought this."

He spoke while opening the small box that had been spurting out white steam. It was a very delicate little thing, there was a fast-moving small wheel in the middle, connected with a shaft, the outer had several shining golden rings. The word 'Ling' was inscribed in the corner, revealing that it was a product of Ling Shu Institute.

"This is the prototype given by Ling Shu institute. When turning, this axis will always point in one direction," Ge Pang Xiao pointed, "It is this one - it is more accurate than the compass, but it runs on Ziliujin. I heard that it was rejected by people above even before the final product could come out. Master Liao Ran and I secretly made one. Before we left, I had taken one small bowl of Ziliujun from big brother's sword training puppet."
