While studying, Lu Han found that although he had traveled here, the historical content was still the history of the earth, and the geography was also about the seven continents and four oceans of the earth.

Although these are memorized contents, Lu Han did not memorize them, but classified the knowledge of each unit and organized it into a mind map in his mind.

As long as his mind moves, the relevant knowledge points will appear in his mind in the form of pictures, which greatly improves the depth of memory and learning efficiency.

For the seventh-grade subjects, Lu Han was most interested in biology, and he was very happy to learn, the only shortcoming was that the human body structure of the Douluo Continent was relatively superhuman.

For example, soul power cannot be explained by conventional biology, and if Lu Han appears on Earth in the current incorruptible body of King Kong, he will definitely be arrested by scientists for experiments.

"The nervous system is made up of the brain, spinal cord and the nerves they emit and regulates ......"

"The digestive system consists of the mouth, pharynx, esophagus, stomach, intestines, ...... Anus! ”

"The blood-body circulation route is: left ventricle→ aorta→ arteries at all levels→ capillary network of all parts of the body→ veins at all levels→ superior and inferior vena cava→ right atrium......"

“……”

The sound of Lu Han's reading echoed in the room, and the outside of the room was already quiet, and Lu Han sealed the entire room with his soul power, so it was impermeable.

And so it passed.

Early in the morning, Xue Qinghe invited him to a meal and tried to win him over, but Lu Han politely refused, because Qianrenxue did not have a taste like Bibi Dong.

Xue Qinghe was not annoyed either, at least in her opinion, the two would not become enemies.

Second, Lu Han molested a maid and asked her to beat her back for an afternoon before letting her go (there was no excessive physical contact during the period, just beating her back)

Third, Avalanche came to him and gave him 100,000 gold soul coins, and then the two of them drank a few glasses.

Fourth, learn!

Fifth, learn!

……

It wasn't until the tenth that Lu Han finally mastered the knowledge of the seventh grade, and the next step was to start frantically brushing the questions.

One thousand points for one level, ten thousand points for upgrading to ten levels, according to two or three points for one question, Lu Han almost has to brush four thousand questions to break through Contra, and the amount of work is huge!

Just when Lu Han was about to brush up on the question, he noticed something strange in the room, an unusual aura.

"Who!"

Lu Han snorted coldly, releasing the powerful spiritual power of the Spirit Realm, "Smack!" Lu Han flashed a ghost and rushed out of the door, looking around coldly.

No one! It's business as usual! Unusual again!

"Where do you dare to come out?" Although Lu Han didn't notice the clues, he knew that he had been targeted.

Could it be a thousand snows?

No, Qian Lingxue doesn't have a master of this strength around him at all!

To be able to do such a traceless surveillance, this Rao cultivation is definitely above level ninety-seven.

The most terrifying thing is that the other party's mental power must be higher than him.

This Qi Lu Han has been immersed in learning, so he didn't notice anything unusual, but he knew that the other party must be staring at him Qi.

Lu Han looked at the side of the Taishang Palace, that is, the place where the priests of the Dou Imperial Family were located, and only that place could it be possible to hide the powerhouses of this level.

"It's not good to stay for a long time, it looks like it's gone!"

Lu Han didn't plan to go back to clean up, just as he stepped forward and was about to gallop away, an old voice suddenly sounded.

"Brother, please stay!" A figure came one after another, looking at Lu Han with a smile on his face.

The man was wearing a golden mask and had a bundle of crane hair behind him, apparently an old man.

Although Lu Han couldn't perceive this Rao's specific cultivation, he was sure that it would not exceed level 94.

And the breath is not right, it's not him!

"Son, I've seen the priest!"

Lu Han said humbly, in fact, he was looking around all the time, and the hidden aura was the most terrifying.

The old man said, "Brother, the high priest wants to invite you to the Taishang Hall to see you, please." ”

Hearing this, Lu Han felt deeply uncomfortable, even the title Douluo was just a messenger, you can imagine how terrifying the so-called high priest was.

"If the son has something important to do, he won't go, farewell!"

Lu Han ran away!

When he flew into the air, three more figures flew out from the direction of the Taishang Palace, blocking Lu Han's way.

The same golden mask, you can't see the true face.

One of them: "It's all here, why don't you sit in the Taishang Palace, it's good to do the friendship of the landlord we fight." ”

"Are you right? Honored guests of the Wuhun Palace! ”

Groov!

Sure enough, I was recognized!

In fact, from the moment Lu Han entered the palace, the Taishang Palace had already sent someone out to investigate Lu Han's origin, and it was not a difficult matter.

"What do you mean? The four Title Douluo stopped me from having a dozen sons, isn't it too shameless? "Lu Han's words are not good, if he doesn't fight today, I'm afraid he won't be able to leave.

The first priest smiled and said, "You are not an ordinary son, for people who are not ordinary, our Taishang Hall naturally has to entertain them with the highest standards." ”

"Good! For me, I'm afraid this kind of formation is not enough, why don't you speak out! ”

Lu Han was majestic, and the Origin Murderous Qi spread out, directly sweeping out the four Titled Douluo who were no more than level 95.

And then...... Turn around and run!

"Boom!"

A bell enveloped the land, like thunder, resounding through the clouds, below the palace, shocking everyone.

"What's going on! Enemy attack? ”

Thousands of soul masters of the Imperial Forest Army gathered, and dozens of soul saints came after hearing the news, led by Zhou Yuan.

Xue Qinghe, Avalanche and the concubines in the palace also moved, including the Snow Night Emperor also looked at this side!

"Bucket Bell! It's the high priest, and his old man actually sacrificed the bell, what happened? ”

Xue Qinghe sweated even more, and his heart was so cold that he was shackled.

Because those who are covered by the bell will not only be unable to escape, but will also turn into pus in a moment or three.

The most important thing is that the person covered by the bucket bell is Lu Han!

At this time, the voice in the Taishang Hall came again, the sound was like a bell, and it was like an oracle, which made people bow down.

"Your Excellency's age, but you have such a cultivation, it's really shocking, since you're here, then stay!"

I only heard his voice, but I didn't see his people, which forced Ge to take care of his life.

Lu Han's heart hung by a thread, knowing that someone with such a compelling qualification must be a cultivator above level ninety-eight, no wonder it made him feel uneasy.

This bucket bell can seal everything, even the void has been blocked, and his fog concealment technique can't jump out at all.

Moreover, he also had to endure the pain of refining furnaces, if he hadn't had the body of King Kong, this kung fu would have turned into a pool of blood.

"Predecessors of the Dou Empire, I have no grievances with you, why do you want to trap me here?" Lu said coldly.
