"z=ax+by(ab≠0), this problem can be seen at a glance is a linear objective function, in this case, there are two considerations, one is b>0, when the line passes through the feasible domain and the intercept is maximum on the y-axis, the z-value is the largest, and the z-value is the smallest when the y-axis intercept is the smallest; Similarly, the other is b<0, where the z-value is the smallest when the straight line crosses the feasible domain and the intercept is maximum on the y-axis, and the z-value is the largest when the intercept is the smallest on the y-axis......"

The performance of the forest rabbit is the performance of the poor student.

When she listened to the lecture, she sat next to Xia He, well-behaved and lovely, but Xia He could tell at a glance that this girl was either ignorant or in the sky.

Rotten wood cannot be carved!

Xia He stretched out his hand: "Rabbit, look at my hand." ”

"What's the matter, Master?" Because it was a digression, Lin Rabbit suddenly became energetic and looked at it intently.

"Is it white or not, tender or not?"

"White and tender!"

Syllable!

The white and tender big hand slapped the back of Lin Rabbit's head, and then Xia He said sharply: "Although my hands have become white and tender, it's no problem to beat you, Lin Rabbit, I've already told you this question twice, you go home for me now, if you don't understand it when you come back tomorrow...... I'll give you a taste of the King of Thunder and Lightning! ”

"Hmm!" Lin Rabbit hugged his head to prevent squatting, and said aggrievedly, "What is the Thunder and Lightning King?" ”

"This." Xia He's fingers touched her fingers, and suddenly a faint electric current was conducted, which made the little girl excited, "How is it, it's very cool, right?" ”

"Static electricity?"

"No, I'm telling you, I'm mutated, if you don't study hard, I can electrocute you like an electric mouse!"

Lin Tuzi looked at Xia He with some horror and stammered, "Really, really? ”

"Really."

The little girl immediately stood up and ran out.

After a while, he pedaled back again, picked up the lost schoolbag, secretly hugged the empty bowl where Xia He had finished eating, and ran away again.

"Hit the door for me!"

Pedal Pedal Ped

Bang!

Pedal, pedal......

After confirming that Lin Qianzao left, Xia He sat up from the bed with another carp, he rubbed his body, and only went to take a bath and sleep after being stinky for a while.

"Fortunately, Dad's clothes are still there, so I won't be able to go out."

"But try not to go out...... The changes are too great, Lin Rabbit can see it, and my aunt is probably more able to see it......"

Following.

Lin Qianzao sent a breakfast of eight-treasure porridge + sauce cake before going to school.

After Xia He finished eating, he directly entered the creation world.

Because the time of the creation world cannot be reversed, when intelligent creatures were not born before, Xia He would set the time ratio of one second equal to one year, but now that intelligent creatures were born, in order to prevent himself from skipping the wonderful time, he always set one to one when he was sleeping, and then accelerated the viewing after entering this world.

The Titans of the city-state era began to grow faster.

The emergence of bronze and iron tools has promoted the process of civilization, but the concept of the state has not been formed, and after hundreds of years of development, the Titans have formed a special system -

The theological system.

Although Xia He called them Titan Giants.

But according to their own statement, they are the children of God the Father, and therefore gods, so they call themselves gods, and because of the long fusion with the genes of the earth's creatures, they have formed seven main god systems, which has something to do with the color of the third eye of the men.

The seven gods are:

Sun God (Yellow Pupil Color), Fire God (Red), Water God (Blue), Wind God (Green), Longevity God (Black), Thunder God (Purple), Ice God (White).

In fact, it is equivalent to seven large tribal alliances.

There are large and small independent families under each god system, but there are families in the core, taking the sun god system as an example, the core family is the sun god family, this family is fused with the genes of various organisms that can emit light on the earth, and all of them can shine without exception and become light people, which is very similar to Xia He, the giant of light, and his status is very respectful.

The seven major god systems were independent, just like in the Warring States period, conquest, marriage, and alliance with each other.

"Strange thing...... They seem to have come to a standstill. ”

Xia He majored in history when he was in college, and he has a lot of research on this kind of thing.

Now.

After occupying the hinterland plains of the eastern part of the continent, this group of gods seemed to have stalled their exploration and focused on the civil war.

But the civil war is over.

After the development of civilization to the Iron Age, there was no progress, and the idea of a state did not appear...... Don't look at the gods are very powerful, but this is only a tribal alliance, not a country, and the core family is not a word.

"Forget it, let's speed up."

Xia He was not interested in watching this group of ants play civil war.

Time continues to accelerate.

100 years, 200 years, 300 years...... After six hundred years have passed, the situation of the gods is still the same, no one of the seven major god systems has been destroyed, but the sphere of influence has changed in these six hundred years, for example, the original most revered sun god system has become the weakest one, and has been driven to the westernmost part of the eastern hinterland plain, which belongs to the frontier, close to the Gobi and desert, and the land is barren.

There is no way, the Sun God System is an imitation of Xia He's image of a giant of light in the final analysis.

But...... Why can you only shine a fart, can you shine when you are fighting?

"Sir." The fool suddenly spoke, "Retrieve an optimal template, do you want to check it?" ”

Xia He has a little spirit at this time, after all, this thing is like watching a movie in the morning, even if it is attractive at first, the spirit will be tired: "Time 1:1, call up the template." ”

A red arrow appeared in front of him, guiding Xia He to the west of the Eastern Hinterland Plain.

The seat of the Solar God System.

But it is the eastern border of the solar god system, in a city called Atul.

At this moment.

A great battle is breaking out here, and the allied forces of the Wind God, Thunder God, and Vulcan Sect who have trekked from the east have broken through the walls of Atul, and the two sides are locked in street fighting.

It's a pity that the sun god system is weak after all, and it is losing and retreating.

Xia He saw the midpoint indicated by the red arrow.

It was the center of Atul City, and it seemed to be a small branch of the Sun God family, and in the open courtyard, a man with a glow all over his body held up a bloodstained, wrinkled skin, and obviously newborn child: "This must be the most perfect child that the Father has given us, he has every powerful ability imaginable, and in time, he will definitely lead our solar god system to rise again and reclaim those fertile lands......"

The man's light faded, and he looked at the baby as if he were looking at a work of art.

Surprise, appreciation, and a hint of reluctance.

"Wu ......" A woman was helped out and looked at the man with a blank face.

The man named U chuckled and handed the child to the woman: "His name is Ra!" After finishing speaking, he resolutely picked up the weapon on the side and walked out of the house.

"Let's go together." The woman pleaded.

"Sons of the Father, do not shrink back!"

————————

"Ra, whose name means 'sun', has super endurance, the ability to fly, the ability to lightning, the ability to emit light, the ability to burst and sustain, and can split and live a long life...... It is the product of deliberate marriage and reproduction of the Sun God family, his father's name is Wu, he is the God of War of the Sun God System, and his mother's name is Gaia, who is a member of the core family of the Longevity God System, and he has the lighthouse jellyfish gene, and he has the characteristic of regaining his youth after aging...... "The fool said a large list of abilities that dazzled Xia He," Sir, do you choose the fusion template? ”
