He stared at the design drawings and fell into contemplation, until Lu Shaochuan came in and was interrupted.

"What are you doing?" Lu Shaochuan asked suspiciously.

Su Shuangjiang didn't plan to tell him, he would give them a surprise when he was done.

"It's nothing, I'm thinking about Tian Ji." Although there was an idea before, it has now been overturned.

Tianshu patrols, Tian Xuan investigates, and Tian Ji wants to get a bionic machine that is more suitable for ordinary people.

"Suitable for ordinary people? Call the police?" The main purpose of the two bionic robots that Su Shuangjiang made before was for protection, so for ordinary people, the most direct method is to call the police when they encounter problems.

But some people can't call the police.

Many times, when people encounter gangsters, the best way is to run away, especially when alone.

In this case... "Call the police and intimidate?"

Oops, when it comes to intimidating Su Shuangjiang, the snake bracelet comes to mind.

In the normal state, it is a wide snake-shaped bracelet, which is tightly attached to the wrist. As soon as the heartbeat is sensed, the alarm mode and the intimidation mode are turned on.

If the bracelet is held by the enemy, the attack mode can be turned on, which can give the owner time to escape.

"Huh? What kind of bracelet is that?" Lu Shaochuan was a little moved, but he couldn't imagine what it would look like.

Su Shuangjiang simply took out the scratch paper, roughly sketched the outline of the bracelet, and then drew the attack pattern.

"Look, snakes have fangs, and pythons strangle their prey by entangling them, so we can combine them." Robot snakes are non-venomous, but that doesn't mean that bites don't hurt.

Besides, don't underestimate the power of entanglement.

"If that's the case... Then the material is made of silicon-aluminum composite material? Anyway, it is not used for search and rescue and does not need to use soft materials... In fact, spiders can also be used, and their claws can be attached to the wrist, and can also act as a watch. The claws hooked the prisoner..."

Lu Shaochuan just watched Su Shuangjiang sitting on the ground and kept thinking, he couldn't understand what the other party was saying, he only heard search and rescue... spiders and so on.

He picked up Su Shuangjiang's whole body, because it was a familiar atmosphere, Su Shuangjiang didn't come back to his senses.

It was an hour later when he woke up from his contemplation.

"How is it? Tian Ji, what are you trying to do?" Lu Shaochuan looked at Su Shuangjiang, who was still a little dumbfounded after he recovered, and couldn't help but stretch out his hand and squeeze it.

"Snake..." The snake-shaped robot is simply versatile. It can not only camouflage an ambush, but also detect the enemy's situation, and it is even easier to use in areas such as rain forests. Similarly, explosives can also be installed at one of the joints. to attack the enemy.

Lu Shaochuan listened and suddenly felt that something was not right. What is the use of explosives in one of the joints?

"This reference annelids, annelids such as earthworms, etc., their bodies are divided into individual segments, and each segment has a nervous and circulatory system."

Therefore, Tian Ji can refer to the annelid animals, install explosives in each body segment, and use it as a time bomb when it reaches the destination.

Seeing the doubts on Lu Shaochuan's face, Su Shuangjiang explained: "The snake-shaped robot is not necessarily a snake. Tian Xuan also refers to the beak of a woodpecker and the stagnation of a hummingbird."

It is said to be a snake, but it can also be said to be a reptile.

"Is that so..." Lu Shaochuan nodded beside him. In fact, he didn't quite accept creatures like snakes.

"Because I look at the terrifying QAQ that is slippery and ice-cold", let alone touching it, I feel creepy when I look at the pictures.

When Su Shuangjiang heard him say this, he suddenly asked, "Then the seven people in your family don't like it, right?"

"No!" Lu Shaochuan instantly showed a lifeless look, and said, "My mother and my sister like it very much, whether it's a pet snake or a python, they all like it. The only two in the family can't accept it, that is, me. Just dad and me."

Thinking of this, Lu Shaochuan couldn't help choking.

The women in his family are too strong, let alone snakes. The last time he saw the girl touch a spider, he almost had a cardiac arrest.

"Fortunately, it's a pet spider, it's not poisonous, otherwise I'd be scared to death." Why are only the men of the Lu family afraid of this kind of thing?

The more Lu Shaochuan thought about it, the more he felt aggrieved. Are you afraid that reptiles are engraved in the Y chromosome? QAQ

Seeing Lu Shaochuan whose whole person was in self-doubt, Su Shuangjiang comforted him dumbfoundedly.

However, among them, he also discovered one thing.

"Don't you know the difference between annelid animals and snakes? Have you forgotten about biology?" During this time, I have been studying physics and mathematics. Biology and chemistry are just explaining the content of the textbook, but I didn't expect to forget this basic knowledge. .

"Eh? Huh?" Lu Shaochuan, who was still sad, instantly regained his composure. He stared vigilantly at Su Shuangjiang in front of him, for fear...

"That's good, I'll sort out your knowledge points for you in the past few days. Next week, there will be one paper per day for the four courses of mathematics, chemistry, biophysics."

One class a day, and the remaining three days, one day, one math day and one general science.

"Then... what about the last day?" Lu Shaochuan looked at Su Shuangjiang tremblingly.

Su Shuangjiang smiled softly, patted Lu Shaochuan's head, and told him a painful fact: "Of course it's math in the morning, and comprehensive in the afternoon."

You thought you could escape? Impossible.

When he finally left, Lu Shaochuan was in a trance. Didn't he come to comfort Su Shuangjiang?

Then why did you leave with seven more papers?

Oh no, math in the morning and science in the afternoon, that adds up to eight copies! Help!
