Since the team left Russia two years ago, the research on the underground laboratory site has not stopped, and the party led by Lie has really put a lot of effort into this research, and this side has finally made a breakthrough.

After Xiao Liu returned to China with Bingxiu, he also joined the team, and the two of them have been very good this time. At that time two years ago, everyone also understood why Lie was called Bingxiu, and Xiao Liu also acquiesced to this godfather in his heart.

And Li actually made an exception to join, but Li's task was not to conduct scientific research, but to carry out some logistics work, which also greatly reduced Xiaochu's sense of disparity.

That breakthrough is really thanks to the discovery on the other side of the column, and in Bingxiu's guess at that time, half of the guesses about the entrances of the six branches were correct, and the branches were indeed full of star maps.

But one thing is biased -

It's not about going to those six places looking for a unique sound. Instead, I went to find six people in those six places.

These six people are all different-

The first person is unable to hear, unable to speak, paralyzed and has no sense of touch, loss of smell, loss of taste, and can only see.

The second person is physically intact and has a sense of touch, but he is also unable to speak, and his senses of hearing, smell, taste, and vision are all out of order.

In the same way, the third person only has the sense of hearing, the fourth person has only the sense of smell, and the fifth person has only the sense of taste.

And the sixth man, the one from St. Petersburg, demanded to be able to speak and sing movingly.

The pattern of the entrance does depict a certain place, but it would be more accurate to say where the six men lived.

So, how did the column discover this?

First of all, the column is a lot of effort and a lot of people in the team. Secondly, during an expedition, because of the habit of smoking, when knocking on the tobacco pouch, it was found that the sound from the ground was wrong, and that position was under the pillar where the flower was placed.

So Lie seized on the anomaly, and began to dig cautiously from the ground on the left, and finally after about two weeks, he found a relatively small dark room underneath.

The darkroom is really not big, but the amount of things inside is not ordinary. There was also a small pillar in the middle of the dark room, and on it lay an object quietly, which was a letter, a letter to posterity, a letter from Professor Geert.

The letter was sealed with a thick layer of crystal, and the crystal didn't even have a gap, and I really don't know how the letter was put in, it was simply a work of heaven. However, thanks to the protection of this crystal, every word of Professor Geert's letter is very clear and vivid.

However, in order to ensure the smooth progress of the research and to ensure the safety of such important objects, the letter was kept completely confidential.

But what exactly is written in Professor Geert's letter?
