Yu Fei followed the tracks left by the opponent and quickly caught up to the middle. From a distance, he saw a figure squatting under a tree.

After taking a few steps closer, Yu Fei frowned because that person was not Xu Guangqi. From the back, he looked much stronger than Xu Guangqi.

Instead of alarming the enemy, he walked over gently to see what the other party was doing.

After getting closer, I realized that the man had brought a lot of things, with at least four or five instruments on him. He seemed to be constantly measuring something and recording the data.

Yu Fei stood behind the other party, but the other party didn't notice it at all. He was still doing it very carefully and stopped to think about it after a while.

After recording, the man took out a small shovel, squatted under the tree roots and dug hard. Yu Fei still didn't bother him. He saw that the other man quickly dug a small hole on the ground, and he didn't care about the damage to the surroundings.

The soil was scattered around randomly.

Soon the other party dug out a truffle, which was the size of a fist and looked like a piece of potato.

The other party quickly began to measure the underground soil data. Yu Fei took a look and saw that it seemed to be humidity, temperature and other things.

Yu Fei habitually took out a cigarette and lighter and lit it with a click.

The man was startled by the sudden sound. He jumped up suddenly and turned around to look at Yu Fei. Yu Fei looked at the cigarette in his hand awkwardly. Even he had forgotten this habitual action.

"Who are you?"

The other person looks to be in his forties or fifties, wears glasses, and has a temperament similar to that of a teacher.

"Exactly, I also want to ask this question."
