Li Ya and Yuan Zhengwei went to the other side of the bamboo forest, where they had to observe two adult male pandas and get some data.

These two male pandas, numbered 55 and 56, are the long-term subjects of their research group, and they have not come to observe once or twice, although the base requires no active contact with animals, but for some experimental purposes, it is normal to observe nearby.

In the past, even when they were in the panda's line of sight, the panda would not pay attention to them. In fact, because the food provides less nutrients and energy, pandas eat more and move less. Especially adult pandas, after they are full, they can basically not move.

But today, when the two of them appeared in front of No. 55, No. 55 was obviously a little agitated, and kept looking at the two of them while eating.

After looking at it for a while, No. 55 seemed to be enraged, dropped the bamboo in his hand, jumped up and rushed towards the two of them.

Li Ya and Yuan Zhengwei quickly withdrew from the original observation position, but No. 55 chased and fought relentlessly, and after escaping around a few bamboos for a while, Yuan Zhengwei was surprised to find that No. 55 ignored him at all, even if he stood still, he would run past him as if he didn't see it, and chase Li Ya with all his heart.

Li Ya ran out of breath, you must know that the body of an adult male panda is 80 kilograms, and if he slaps or bites, he will die directly, at least half a life will be removed.

If it weren't for the bamboo forest, he would have been running back and forth again, and he really wouldn't have been able to escape with his speed.

There was no way, Li Ya could only flee towards the territory of another panda, counting on No. 55 not daring to chase after him.

Male pandas all have their own territory, and the sense of territory is particularly strong, if No. 55 follows him into the territory of another male panda, he doesn't need to think of a way, the other male panda will take the initiative to attack.

Sure enough, after he escaped, No. 55 stopped at the border of his territory, and roared at Li Ya a few times before slowly walking towards his own territory.

Li Ya gasped and waited in place for a while, Yuan Zhengwei ran over, he just took advantage of the male panda to run away and packed up the luggage and instruments on the ground, and then caught up.

"Number 55 may be in heat." Yuan Zhengwei said.

Generally, pandas come into estrus around April and end in May, but observations in previous years have shown that the estrus period of No. 55 and No. 56 is different, which is one of the reasons why Li Ya and Yuan Zhengwei came over this time.

"Ma Dan, why are you chasing me when you're in heat? I'm not a female panda! Li Ya said stupidly.

Yuan Zhengwei smiled, "Maybe I think you're too handsome and threatening, so I want to eliminate you?" ”

The relationship between him and Li Ya is not a good friend, but it is not bad either, after all, they are from a research group and often cooperate. Although Yuan Zhengwei has a good temper, Li Ya usually doesn't dare to offend him and give him a look. The two have different research directions, similar research levels, and each other's subject tutors are also of similar status, and even Yuan Zhengwei's subject tutor is a little bit more powerful.

Li Ya is pretentious, looks down on people worse than him, and is not a brainless dog, he will bite people everywhere.

When Li Ya took a breath, Yuan Zhengwei suggested that he should observe No. 56 first, the current state of No. 55 is not suitable for nearby observation, and if it is too far away, the instrument will not work, and it is better to stay in the observation post to watch the monitoring just by looking at them with their eyes.

Li Ya was also helpless, so she could only take her luggage bag that Yuan Zhengwei helped to carry and walk towards the site of No. 56 together.

As a result, the same scene happened at No. 56, and Li Ya was chased by No. 56 behind his ass.

It can't be observed at this time, Li Ya and Yuan Zhengwei, who escaped from the No. 56 territory in embarrassment, looked at each other.

Fools know there's something wrong.

"Go back, go back and study, there must be something wrong with you!" Yuan Zhengwei said.

Both male pandas were clearly chasing Li Ya, not Yuan Zhengwei. Because Yuan Zhengwei tried a few times, he wanted to help Li Ya attract some firepower, so that he couldn't take a breath.

Just like just now, No. 56 seems to have no one else in his eyes except Li Ya, even if Yuan Zhengwei is in the way, it is like seeing a bamboo tree, instead of chasing after him.

As a result, Yuan Zhengwei could only use this way to block the speed of the male panda a few times, allowing Li Ya to run away smoothly.

Li Ya was also very frustrated, and on the way back, he did not give up and went around to the territory of several other pandas, but one of the male pandas chased after him like him, and met the two female pandas but did not move.

Embarrassed, he escaped from the bamboo forest and returned to the hut, where Li Ya collapsed to the floor exhausted.

Yuan Zhengwei took the initiative to sort out some of the instruments he brought and put them away. Suddenly, he looked at the data of a recorder in his hand and exclaimed in surprise: "Li Ya, hurry up and take a look!" ”

This instrument is used to remotely observe and record some physiological states of living organisms, and can measure the subject's heartbeat, body temperature and other data without contact. This was originally a military item, used for the training of special soldiers. Now civilianized in the daily security check of some important locations, through the detected data, you can use the brain to distinguish the possible emotions of the object, if there are people with special anger, nervousness, heart weakness and other emotions, it will strengthen monitoring, and even directly carry out manual security checks.

Biologists also use this instrument to collect daily data on the animals they observe and to accumulate a database in the hope of judging the emotions of the animals.

This is actually one of Yuan Zhengwei's research directions, so he is very familiar with the daily data of pandas, and some mood fluctuation data is also relatively familiar.

Yuan Zhengwei just saw the waveform of the last set of data in the instrument and felt familiar, although he didn't have a brain, but according to his understanding, this panda was extremely angry.

He thought about it for a while, this should be the data of the No. 55 male panda, at that time they were observing nearby, it was he who turned on this instrument to collect data, until No. 55 ran away after Li Ya, and he turned it off when he was packing his luggage, and there was no chance to open it again.

Therefore, No. 55 may indeed have chased Li Ya because of anger.

After listening to Yuan Zhengwei's analysis, Li Ya also felt inexplicable, he didn't do anything to make the male panda angry.
