In the eyes of the people who kept the covenant for thousands of miles with great admiration and shock.

Chen Changsheng continued: "Chemistry, as the name suggests, is a science, if you want to learn and learn well, you must bury your heart, study hard and persevere. ”

Only in this way will you be able to understand more clearly the nature of this world. ”

Su Qingxue raised her hand and said, "Sir, is chemistry difficult?"

When Chen Changsheng heard this, he was silent for a while, and said, "If you learn and understand, you won't feel difficult." ”

Su Qingxue: "!!"

If you learn and understand, you won't feel difficult?

Doesn't that mean that chemistry is hard?

"That's right! How can such a holy book be so easy to learn!"

For a while, the four of them were like facing a great enemy, but they were all very firm in their hearts, and they must conquer chemistry.

When Chen Changsheng saw their solemn faces, he thought they were scared, so he encouraged them: "Don't be afraid of difficulties, you must believe in a truth, there is nothing difficult in the world, as long as you are willing to climb." ”

"You must also understand the truth that the rope saws the wood and the water drops through the stone. ”

After all, there is no such thing as simple success. Only by perseverance and hard work can we achieve success!"

As long as you work hard, work hard, be modest, and be serious, you will definitely be able to learn it. ”

"Where there is a will, there is a way, you must believe in a word!"

"Your dream, chemistry dream!"

Rumble!

The four of them exploded in their minds, and the surging thunder was endless.

At this moment, they have realized that they are gradually about to enter an extremely mysterious state.

It's an epiphany!

However, they forced themselves to suppress the epiphany.

Because, for them, they have memorized this teaching, and after a little understanding, they will definitely get this epiphany again!

However, they know that there are some things that Mr. will only say once, and they can't give up the bigger opportunity that Mr. gave them for the sake of epiphany.

At the same time, they were surprised to find that behind Chen Changsheng, there was a faint three-colored light, which reflected each other, setting off Chen Changsheng like an immortal!

"It's ...... Say what you say!"

"No, it's not just a matter of words, it's a three-color divine light!"

"Definitely three-color divine light! absolutely!"

Seeing these three kinds of psychedelic and magnificent light, the hearts of the four people were shocked, and their hearts were filled with unprecedented shock!

"Three-color divine light, that is the legendary supreme immortal, with his own luck, sensing the Great Dao of Heaven and Earth can only do it, it has not appeared once in millions of years!"

"And the most recent one was 10 million years ago, when the ruthless emperor of the Immortal Cultivation Realm ended the law era did it!"

"Moreover, this is still a legend, whether there is a three-color divine light or not, there is no way to verify it!"

"But, today, I actually saw it!"

"It's so shocking! This immortal master, what kind of big man is he?"

"Da Luo Jin Xian?"

"Could it be that in the legend, the reincarnation of Hongjun Dao Ancestor is not successful?"

The four people of Wanli Shou were stunned and dumbfounded!

They just felt like their whole being was going to crack!

It was a real shock!

The legendary three-color divine light actually appeared!

Unbelievable!

It's unbelievable!

Pretty unbelievable!

So much so that they can't control it directly!

"Shhh

"I'm hiss!"

"I'm still hissing!"

“......”

“......”

Chen Changsheng: "???"

What's wrong?

Can you have a convulsion?

Chen Changsheng was stunned.

He noticed that several people had been staring behind him, so he turned around in confusion.

Well.

Nothing!

That's weird, what are they gasping?

Why are you so shocked?

Chen Changsheng is in a circle, and these people don't see any golden light, no golden light, that is, no epiphany!

It's weird.

Chen Changsheng was completely confused.

He didn't know that with the accumulation of his merits, he already had the ability to sense heaven and earth.

However, because he was a mortal with the naked eye, he couldn't see the three-colored divine light behind him at all, as well as the changes in himself.

Moreover, the meals he cooked before did not contain great rhyme!

And it is precisely because of the increase in merit that the food he cooks contains Taoist rhyme.

This is also the reason why Lin Qingxue and they can't eat the debut rhyme, but they can eat the debut rhyme when they keep the promise.

Chen Changsheng finally couldn't help it, and asked very suspiciously, "What's wrong with you?"

The spirit of the four people who kept the covenant suddenly shook!

Then, their expressions became extremely nervous.

"There is a three-colored divine light behind him, and he even wants to ask us what's wrong?

"By the way, Sir is low-key, humble and polite! He must know that we have discovered his identity! The reason why he asked us this must be to make us turn a blind eye to the three-color divine light!"

"Surely let's continue to treat him as an ordinary mortal!"

"Yes, definitely!

Thinking of this, the four of them were immediately impressed by Chen Changsheng, "Sir, you are really a supreme master! You are so humble and low-key, and you speak so tactfully, without a trace of domineering tone!

The four of them were impressed by Chen Changsheng's great means and magical powers just now!

And now, they are impressed by Chen Changsheng's supreme virtue!

Therefore, they were completely conquered by Chen Changsheng!

Sir, a master!

They were immensely immensely admired.

But at the same time, they looked at each other, tacitly agreed, and said respectfully in unison: "Sir, it's nothing, it's just that I was shocked by the knowledge of chemistry." ”

Chen Changsheng: "......"

It seems that he hasn't officially started yet.

Is this shocking?

Chen Changsheng was speechless, thinking to himself, people in the immortal cultivation realm are quite easy to be shocked.

Then, Chen Changsheng continued: "In this case, then let's officially talk about my requirements for you to learn chemistry. ”

The four of them looked solemn.

What are the requirements for studying chemistry?

It's definitely the most important presence!

It must also be the key to helping them become the boss of the Ascension Realm!

They had to listen carefully and not let go of a word.

It has to be all memorized!!

Therefore, they said with great respect, "Sir, please speak!"

Chen Changsheng nodded and said, "First of all, you must understand the concept of "quantity of matter", know the concept of molar mass and the calculation method of molar mass of different particles. ”

"Secondly, learn the simple calculation of the quantity of a substance, understand the basic meaning of the quantity concentration of a substance, and master the simple calculation of the quantity concentration of a substance. ”

Finally, learn how to calculate the dilution of a solution, understand the interrelationship between the mass of a substance, the molar mass, the quantity of a substance, the number of particles of a substance, the quantity and concentration of a substance, and the related calculations. ”

Thereupon.

Four people who keep the covenant for thousands of miles: "??????"
