When Song Tao, Chen Yunzhe and Hou Yao rushed to the third floor of the main teaching building where the defense was located, the previous round of defense for resource exploration engineering had just ended, and the new round of defense teachers were taking their seats.

Song Tao stood up panting and said, "Luckily I was not late."

Then he said to Chen Yunzhe and Hou Yao: "I have revised the errors in your paper, so there should be no problem. Just don't be nervous at that time."

As the student with the highest score in this class and is also the best friend of the two, Song Tao naturally took on the task of revising their papers.

Chen Yunzhe nodded: "My level is much higher than that of Hou Yao. Taozi, I think you should take good care of him."

Song Tao nodded in disagreement and cast inquiring eyes at Hou Yao.

Hou Yao spread his hands and said, "Although my grades have always been average, this thesis defense is not a difficult task. It is much simpler than the final test of the high-level line generation. Don't worry."

Then Hou Yao looked at the time and said, "Taozi, Chen Yunzhe and I are in the same group, let's go first."

Song Tao watched the two leave. They didn't ask Song Tao about the defense before leaving, because in their opinion, how could the students in District 1 of SCI need to worry about this?

After Song Tao separated from them, he went to the classroom where the fourth group was located alone. The first student in the fourth group is now in the defense, and Song Tao was the second person behind him.

At this time, other students were reviewing their speeches to avoid being asked by the defense teacher and unable to come to Taiwan. Song Tao was calm and calm. His three months of internship at the quality inspection station allowed him to see many big scenes and his psychological quality improved a lot.

Fifteen minutes passed soon, and the first student walked out of the classroom after completing the defense. Seeing her relaxed expression, she should not be embarrassed.

But she muttered: "How to defend the teacher is different from the one who notified in advance? I would be fine if Teacher Zhao was there."

Song Tao didn't pay attention to what she said and walked into the classroom.

I saw that on the LED banner in front of the classroom, there was a look at the graduation design (thesis) defense meeting of the major of Gemology and Materials Technology at Huachang University of Gemstones and Materials Technology. Five defense teachers sat in the first row of the classroom.

However, when Song Tao closed the classroom door and saw who these defense teachers were, his heart skipped a beat.

Song Tao said in surprise: "Li Da? He Chuan?"

Generally speaking, there are five teachers in each group of Huachang Dida Defense Council, three of which are teachers in this major, one is a school leader and the other is an expert in related fields outside the school.

Judging from the ranking, Li Da should be the chief examiner, but Song Tao clearly remembered that the fourth group of examiners who were notified before was Professor Zhao, the vice president of the Jewelry College, and the school leader was Minister Gong of the Teaching Affairs Department.

How did it become Li Da and He Chuan now?

Thinking of what happened recently, Song Tao's keen sixth perception told him that he might be in trouble today.

However, with the concept of real gold not afraid of fire, Song Tao calmed down and thought nothing had happened. He went on stage to open the PPT he had done, and first introduced himself generously and appropriately.

After the self-introduction, Li Da said lightly: "Let's start the official content."

Song Tao nodded and introduced: "The title of my graduation thesis is: The current development status of topaz coating technology, first..."

However, before Song Tao finished his first sentence, Li Da interrupted him: "Your name is Song Tao, right?"

Song Tao smiled and said, "I have already said it when I introduced myself, and my name should be on your list."

Li Da asked in confusion: "My schedule shows that your paper did not participate in the initial review of the paper at the beginning of the semester and during the semester as required. You must explain the situation."

Song Tao felt that this problem was inexplicable, but he still said calmly: "Professor Li, I had submitted an application form for completing the graduation thesis off-campus in early March, and the Ministry of Teaching Affairs also approved it, so there is no need to participate in the preliminary review of the thesis."

Seeing this, a teacher next to him leaned over and looked up the information in front of Li Da, pointed to one of them and said, "Professor Li, this is his application form, there is no problem."

"The students who can participate in the defense have passed the defense qualification review, so you don't have to worry about this." The teacher kindly reminded Li Da.

Li Da's focus of work has shifted to the quality inspection station for many years and has not been a teacher for undergraduate thesis defense for a long time, so the relevant process is already very different from that year.

Li Da originally wanted to find Song Tao’s mistake when he came up, but unexpectedly he found the wrong place, so he said lightly: “Then keep going.”

Song Tao frowned, but he couldn't say anything, so he could only start explaining the content on PPT again.

"The topaz coating process has gone through three stages. The first is to spray oxide film, the second is to change the film layer structure into an alternating layer structure, and the third is to coat the film and then heat treatment is performed to change its own color."

“The first one…”

Usually, the defense time is fifteen minutes, of which ten minutes are made by students' explanations based on the content of the graduation thesis, and the remaining five minutes are asked by the defense teacher.

Song Tao has had experience in publishing articles many times. Even though this graduation thesis is not as good as the ones he published in "Shibao", it is still detailed and accurate, with very sufficient arguments and data.

Therefore, Song Tao completed his ten-minute explanation smoothly, and then stood quietly on the stage waiting for the teachers to ask questions.

In addition to Li Da, two teachers from the Jewelry College, school leader He Chuan, and one was an off-campus expert. He was Professor Zhu Sheng from Huguang University.

This is the routine of Huachang University of Geosciences. In the defense teacher group, an off-campus expert will inevitably be invited. In order to show this "foreign guest" the strength and rigor of Huachang's land, the examiner will deliberately ask students some in-depth questions.

Song Tao was prepared for this.

Professor Zhu Sheng from Huguang University has been listening to Song Tao's explanation carefully. He had learned in advance that the student named Song Tao on the stage is the first in the gemology major of Huachang Di University. He has a brilliant record of publishing three SCI District 1 papers within half a year.

Therefore, Zhu Sheng was very energetic when listening to Song Tao's explanation of PPT. According to the students, Song Tao belongs to the ranks of the gods of learning, and he is also very curious about how strong the undergraduate students at this level can be.

Song Tao did not disappoint him. According to Zhu Sheng's estimate, Song Tao's paper was more than enough to publish in the core journal of gemology.

After Song Tao finished speaking, Li Da cleared his throat and asked: "Did you mention that the third stage of the topaz coating process is to carry out heat treatment after coating. Can you tell me in detail about the reaction mechanism of high-temperature coating?"

Song Tao felt a deep heart. He had just mentioned this in his paper, but strictly speaking, it cannot be considered within the scope of his paper's research. The questions asked by Li Da were simply beyond the outline.

Song Tao looked at Li Da and He Chuan, narrowed his eyes slightly, and thought to himself: "They are indeed here to cause trouble for me."

Zhu Sheng was completely unaware of this. He glanced at Li Da and smiled, thinking: "This teacher from Huachang Land University is really interesting. Asking such a difficult question is just to show off to me the high level of their students?"
