"Principal, I can't hold it in anymore." Le Yao could only let go and began to bend down to cover her stomach, with an expression of wanting to wet her pants. "You know, if you hold your urine for too long, it will induce a series of urinary stones and bladder cancer..."

"Haha." Principal Ma smiled kindly, "I saw you just coming out of the toilet ten minutes ago. This person's bladder capacity is between 300 and 500 milliliters. It takes about two hours to form urine after drinking water. After this, when the blood flows through the glomerulus, in addition to the blood cells and macromolecules of protein, some of the water, inorganic salts, glucose and urea in the plasma can be filtered through the glomerulus into the renal cyst cavity to form the primary urine. The renal tubules will reabsorb most of the water, all glucose and some inorganic salts and other substances, and the remaining waste..."

Le Yao:...

Really convinced!

Old Man Ma, are you a doctor or a urology department? Then why are you here to be the principal?

"Principal, I've gained knowledge. I suddenly stopped holding it in. I'll go back now."

"Haha." Ma Lin still smiled kindly, "Oh, classmate Han, I'm going to have a make-up exam in two weeks, right?"

"And." Le Yao made a big alarm. What did this old man do? But he had to have an attitude. "Don't worry, Principal, I'm very hardworking. I will definitely pass this time and I will definitely study hard in the future and improve every day."

"Yeah, it's not bad." Ma Lin nodded with a smile, "Your little cake is well made."

Le Yao blinked her eyes: "It's good if the principal likes it."

"What a pity, it's just a little smaller."

Le Yao's eyes lit up: "Oh, I like cooking, I will definitely make a big one next time?"

"Then let's just say that." Ma Lin smiled so hard that he was invisible. "Sit down and go to class quickly." After achieving his goal, there was no need to stay. The student respected himself a piece of cake, which was not considered a bribery. He said a little too much, so he quickly went back to have a sip of tea.

Hao Kai and others were in the back row, so naturally they heard the conversation between the two, and couldn't help but look horrified. Brother Jue bribed the principal? He actually came forward to block the people back in person. I have to say, this trick is amazing, and he inexplicably sympathizes with that woman. What's going on?

Qiao Qiao looked at Le Yao who was blocked back with no words and patted her shoulder sympathetically: "Jie Ai." She deserves to be the Lord, but she can actually let Old Man Ma guard the gate for him.

What Qiao Qiao didn't know was that it was not the Lord who brought Old Man Ma to come, but the cake.

"I love studying." Le Yao looked at Qiao Qiao sniffing and clenched her fists. She was an ambitious and good young man, and skipping classes was not what she should do.

When Nangong Jue walked into the classroom, he saw Le Yao sitting in the corner of the back row. He looked at her eyes widened because of surprise, and was frustrated after seeing her slipping away but being blocked by the principal... The corner of his mouth curled up slightly: "Hello everyone, I am Nangong Jue. I also graduated from the Finance Department of Jiaotong University five years ago. Today, I am very happy to be your visiting professor. Today I will tell you about the situation of our domestic financial market..."

The staircase suddenly became an uproar.

Qian Meiqi pulled Le Yao: "Is it really my male god?"

"Don't you recognize me?" Le Yao rolled her eyes. The male god? The male nerves are almost the same.
