But he did not plan to rest. He took out a small tool box from under the table and opened the box, which was filled with various electrical components and various small tools.

The flint gold mine cave must exist.

Since the Geological Bureau cannot find it, it must be that the survey method is incorrect.

Through the conversation with the two just now, he learned that the Geological Bureau only has two survey methods. The first is to pass a metal detector, and the second is soil detection.

Su Mo is not disagreeing with these two plans. Logically speaking, as long as underground metal is underground, you can definitely find it through these two plans.

But the facts are right in front of him, so he must think of other ways.

Two hours later, he looked at the small detector in his hand and frowned slightly.

"The detection distance is only ten meters, and the materials are too limited..."

This distance is not as good as the survey equipment used by the Geological Institute now, and there is no material here for him to use.

A good cook cannot cook without rice.

If it is transferred from the country, it will take at least one day.

Su Mo thought about it, but gave up the idea and lowered his head and remained silent.

Five days ago, five corpses of Xia Kingdom suddenly crossed the border and arrived at the Hull Mountains in just one hour.

In other words, Oceania has only less than an hour of evacuation.

He had watched a satellite video. Although the picture was blurry, it could still be seen that the Sakura Kingdom transported a lot of industrial machinery and equipment to the Hull Mountains.

Although not too large, it is very large.

However, after taking over the Hull Mountains, no industrial machinery was found, nor any traces of metal mining were left behind.

Everything seems a little abnormal.

In such a short time, Su Mo did not believe that Sakura Kingdom could transfer all the mechanical equipment, let alone perfectly cover up the traces of mining metal.

impossible!

After thinking through these, a brilliance flashed in Su Mo's eyes. Through such deduction, he determined something that the location of the Flint Gold Mining Cave must be very secretive, to the extreme.

Otherwise, in a place as big as the Hull Mountains, thousands of soldiers and nearly fifty elites from the Geological Academy would not be able to find the Flint Gold Mine Cave in three days?

This is definitely the case!

"Secret place, secret place..."

Su Mo murmured in a low voice, his thoughts quickly moved on. Suddenly, his eyes lit up and his mind exploded.

Have it!

Without any hesitation, he picked up the radio telephone on the table and connected to Li Zhenghai's contact channel, "Director Li, come here for me, I thought of some important things."

Seven or eight minutes later, Li Zhenghai came to Su Mo's tent with breath.

"Teacher Su, what's wrong?"

"Director Li, I should have guessed where the Flint Gold Mine Cave is."

Su Mo didn't say anything nonsense, and said directly: "There are a total of sixteen mountains in the Hull Mountains. Have these sixteen mountains been surveyed?"

As soon as he heard this, Li Zhenghai immediately understood what Su Mo meant and hurriedly said: "Not yet, the mountains in the mountains are not big and steep. The most important thing is our surveying equipment..."

Before he could finish his words, Su Mo interrupted and said, "Director Li, there is no need for survey equipment. You should now order to conduct a comprehensive survey of the mountains of the Hull Mountains, the focus is on the top of the mountain."
