A large number of patrol guards on the mountain were shocked by the sound here.

At this time, the guard of the Academy was renamed security guard by Zhang Feng.

Different from the patrol soldiers, what they hold in their hands is no longer a knife and gun, but a wooden stick called a baseball bat, which is not thick at the handshake, but gradually thickens with the handle.

This is the right given to them by Zhang Feng

It is also a symbol of identity.

When a group of people came to see Zhang Feng waving sticks, they immediately protected Zhang Feng and his two wives behind them. Then they glared at Li Chengqian.

Until Zhang Feng said it three times, it was all right

But in desperation, Zhang Feng could only let the security guard check him up and down. After confirming that he was all right, the security guard left angrily.

But when leaving, Chumo looks at Chumo's warning eyes. Chumo is angry and will go up and beat people.

But I don't want to go now. After all, there are still big things to do at this time.

As soon as the security guard left, Yu Shinan and others also heard the news

After all, the news just made by Zhang Feng is really not small.

When the five came, they looked at the undulating fish on the whole lake and asked in surprise, "Fengzi, what are you doing?"

Seeing this, Zhang Feng quickly bowed down and said, "it's not idle. I'm going to experiment with a new thing. By the way, I want to improve the food."

Several old men stared at the fish on the lake and said, "don't tell us, you made these fish?"

At this time, not to mention how much it was done, it came into the eyes of the lake. The whole lake was full of dense fish.

How much does it cost?

Not to mention everyone here, even the students of the whole college can't finish eating for one day!

Is this or improving the food?

Besides, the whole academy can't hear your voice. Come back, you said you were fishing here?

interesting?

Is it fun?

Ouyang inquired angrily and was about to scold. Seeing this, Zhang Feng hurriedly shouted, "what are you waiting for? Go down to the lake to catch fish! Wait, I'll invite the whole academy to eat fish! It's also a kind of whole fish feast you've eaten for me!"

"Really?"

"Is that true?"

For Chumo and others who are super eaters, Zhang Feng's new gadgets every time are unparalleled in the world.

Now fish is basically stewed in a pot or roasted on a fire.

There's nothing else.

So although there are so many fish that you can jump into your arms after washing your feet, you don't have to eat. Moreover, there are too many thorns and less meat. Who will eat this thing if you have nothing to do?

But Zhang Feng is different.

They had eaten several times in Zhang Feng's tavern

It's different every time.

This is what surprised and shocked them most.

But this time, Zhang Feng said he would invite everyone to a whole fish feast?

Let alone Chumo, they are excited

Even Yu Shinan and others are salivating at this time.

But when you think about business.

Several people called Zhang Feng under the jujube tree.

Seeing that there was no one here, he solemnly asked, "Fengzi, what's the matter with the fish? Why is it after hearing a few sounds?"

"Even if sun Lao goes to take medicine, it doesn't have such great power! How on earth did you get it?"

Zhang Feng smiled.

Pretending to be mysterious, he said, "please wait a minute and I'll give you an answer right away!"

Several people don't understand what Zhang Feng is going to do.

But I'm ready to wait.

I saw Zhang Feng pick up the guy thing just now again, but this time he was going to show them, so Zhang Feng only chose a test tube with a cork the size of his thumb. After the test tube was filled with lime and some sand, he pointed to this way: "your teachers are optimistic."

While talking, Zhang Feng threw the test tube in his hand into the water again.

After what had just happened, the test tube burst again like firecrackers.

"Bang!"

With a small wave rising on the water, Yu Shinan and others suddenly changed their faces.

This experiment used only a small bottle the size of a thumb, but the power was so powerful that several people were shocked.

You can also imagine what just happened on the lake.

But it should be for this reason that the look of several people will be so dignified.

This thing can be used here. What if it is thrown into the crowd?

Ouyang Xun looked at Zhang Feng coldly: "Zhang Feng boy, tell me what you got out of this thing? What's its name?"

Zhang Feng is a little confused.

"This is the one who fried fish. If you have a name, call him a torpedo."

"Mine?"

"What you put in here, I think it's the lime at the mouth of the kiln. This thing can make such a loud noise?"

Zhang Feng knew they had such questions.

No words,.

Instead, after Li Chengqian and others fished up all the fish, they called everyone over and said, "in fact, the principle of this thing is in the textbook called physics I gave you before."

"The theoretical experiment of this thing is called atmospheric pressure and water pressure."
