Lu Han checked inside the base and found that just a piece of material could not be used to find out what could be used to build. At least drawings are required.

The "black crystal" attribute of this material seems to have a very good effect, and Lu Han speculates that if it is used as a weapon, such as the blade of the Tang knife, at least when it is used to attack wild mountain boars, there is no need to worry about the blade breaking.

After drinking a few sips of moon well water, closing his eyes and reviewing the battle with Xuanlong and Liu Haobin at night, Lu Han looked for his own shortcomings.

It's good to say that that guy is a big guy, a power-type opponent, and with his super high agility, he can fully play the advantages of Wing Chun.

And when I beat Liu Haobin, I found that he was also very fast, and the most important thing was that he had a melee weapon like a finger tiger. This made Lu Han not know how to deal with the enemy.

Because he hasn't really fought against the humans who took the device.

Several waves of attacking enemy forces from the other world, on the whole, they are still "monsters", and they do not have the high intelligence of humans.

"It seems that we still need to strengthen our own strength. Lu Han concluded.

He tried to open the bow 1,000 times in "Charged Strike" a few times, but his current strength of 13.1 was still not enough to open a 200-pound super heavy bow for ten seconds, so this was something he couldn't rush to.

He walked in front of the dark practice room and recharged 3 dark coins, spending 600,000 yuan.

Then, in the Weapons Pavilion, spend 1 Fantasy Coin to buy a Brass Knuckle Tiger.

At this point, Lu Han felt that the game system was a bit picky, didn't this thing appear in pairs? 1 fantasy coin, you can only buy one?

In desperation, Lu Han had no choice but to spend another one and buy another brass finger tiger.

Wearing a finger tiger on each of his left and right hands, Lu Han waved his fists in the void, closed his eyes, mobilized the mystery of Wing Chun, and quickly punched a few punches in the attitude of Wing Chun.

Bang Bang Bang!

There was a faint popping sound in the air.

With these two finger tigers, Lu Han gave birth to a kind of confidence, if he meets Liu Haobin again next time, he doesn't need to use * to restrain him, these two melee weapons will have the capital to face the other party.

In addition to bringing these two fingered tigers, Lu Han took a short-handled machete from the two-way storage wooden box and pinned it to his waist. This short knife is bought in the market and is commonly known as a boning knife for the kitchen.

Airplanes!

Lu Han put in 3 fantasy coins and entered the dark practice room.

The familiar old opponent appeared, it was the Iron Tree Man, and this time, five Iron Tree People appeared at once.

In the past, Lu Han had to outwit him with fire attacks, but now that he has a double brass finger tiger, Lu Han wants to use these five iron bark tree men to hone his melee ability.

Bang bang!

Lu Han did not hesitate, closed his eyes and got into the five big tree people, opened his bow left and right, and while dodging the attack of the tree man and the tree branch, his right fist slammed into the trunk of the tree with a Wing Chun fist.

Blunt objects can't do much damage to a high-defense, fleshless, muscular, vegetative monster like an iron trunk.

However, it is not entirely harmless.

The continuous ultra-high-speed punch punches, although they could not hurt the energy core in the trunk, but the two branches and arms were not very thick, only the thickness of the bowl mouth, so if they hit continuously, as long as the strength was high enough, they could be destroyed.

This dark training room is not all about upgrading, but for honing more skilled fighter skills and the use of the finger tiger.

The battle is more difficult than imagined, and the five treants are not just as simple as one more than the previous four, the main thing is that the space in the room is effective, and the more tired the big treants, the less room to dodge and move.

It took almost thirty minutes for Lu Han to break the arms of a tree man. And his fist face, although protected by a finger tiger, but the strong recoil force also made his bones impact.

Without their arms, the Treants lose their means of attack and become a moving target for slaughter.

Lu Han didn't care anymore, turned the target, and attacked the other four tree people.

The difficult battle began again, and after about an hour, the arms of the other four tree men were all broken, and Lu Han himself was covered in bruises, and his body was bruised and purple.

The bones of the arm were shaken by the force of the backlash and almost fell apart.

The last time he outwitted the tree people with fire, Lu Han found that there was an energy body in the trunk of these tree people. It is this energy body that drives the activities of the tree man and provides it with energy.

Now, the five big tree people are at Lu Han's disposal, and what Lu Han has to do is to take out the energy body in their trunks.

Fortunately, I brought a machete with me before I came in, so it would not be difficult to retrieve these energy crystals, otherwise, it would not be easy to do it with my bare hands.

He stayed in the dark practice room for nearly two hours before he could get everything done, and while each tree man gained 5000+ experience, he also gained five energy blocks.

The snow-white crystal block is cold in the hand, like a piece of ice, and it is round and almost the size of a dragon's eye.

It's hard to imagine that such a small piece of something can drive a tree man more than two meters tall, and it has a lot of power and a steady stream.

Putting the five energy blocks in his pocket, Lu Han exited the dark practice room.

He studied the base for a while, closed his eyes, and held the energy block, wanting to feel the breath inside, but ...... It doesn't feel anything special, and if it has to be, it's a little numb, like being hit by a tiny electric current.

"This thing is electrified?"

Lu Han put the five energy blocks into the two-way storage wooden box, and then left the [Land of Illusion].

……

Early the next morning, after Lu Han got up and completed his daily morning jog, he couldn't wait to take out an energy block, which made him curious.

It must have been some kind of energy collection, otherwise it wouldn't have been able to power a treeman that large.

But how can you unleash its power?

Do you need to use positive and negative electrodes to export it like electrical energy?

Doesn't seem so low-level?

Because, judging from the process of dissecting the tree man, such a small block of energy was directly and rudely stuffed into the trunk. And the trunk is just an ordinary trunk and has no life in itself.

I went to class with a small piece of gadgets, but today Han Zaifeng skipped class again, and I don't know what to do.

Lu Han sat alone in the back row of the classroom, the teacher in front of him was teaching theory, Lu Han was bored and took out his mobile phone to play.

As a result, due to forgetting to charge the phone last night, the phone lit up only 20%. For modern people, the failure of the mobile phone is a very painful and insecure thing.

He played the king with Song Yingzhi, who was sitting in the front row, but before the class was finished, the mobile phone ran out of battery.

Song Yingzhi turned back from the front row to look at Lu Han, Lu Han picked up the mobile phone and gestured, there was no battery.

Song Yingzhi originally wanted to sit in the back row with Lu Han today, but several people in her dormitory insisted that she sit in the front.

If he sits in the back, Lu Han suddenly runs out of power and drops during this kind of team battle, Song Yingzhi will definitely pinch his waist a few times, and scold a few words by the way. But now, so far away, the teacher is lecturing again, and he can only say in his heart that Lu Han is really pitting.

Lu Han put his phone aside, and Lu Han took out a small energy block to play when he was bored.

Placed on the table, Lu Han was treated as a glass ball, rolled a few times, and made a rattling sound.

It looks like a vitreous body, but it's not so transparent, and it looks like a certain kind of jade, crispy and numb to the touch.

After playing like this for a while, Lu Han's eyes suddenly caught that the breathing light of the mobile phone on the desktop suddenly flickered.

"Hey, the light is flashing? If the phone is out of battery, will the light also flash?"

Lu Han picked up the phone, fiddled with it a few times, and pressed the power button, only to see that the phone was turned on.

I'm going to have electricity again?

What's going on, the battery is broken?

The first time I thought of the possibility that the battery was broken, but theoretically it was impossible, his mobile phone is the latest fruit XS top configuration, more than 10,000, only bought for a month, how to break?

When powered on, the battery level is displayed at 28%.

That's more power than when you go out in the morning, what's going on?

Lu Han couldn't understand it, and played with his mobile phone to check. During this check, he watched the battery of his mobile phone "pop" again, and it rose a little, becoming 29%.

Lu Han rubbed his eyes, if he hadn't encountered the [Land of Illusions] before, he would definitely have thought he had seen a ghost.

But now that he knows that there is a [Land of Illusion], there are various otherworldly secret realms, and all kinds of magical props, Lu Han's psychological endurance has become very strong.

He immediately calmed down, touched the phone, and felt that the phone battery was not hot, and after temporarily ruling out that the battery was faulty, he fell on the small energy block.

He put the energy block a little farther away, about 30 centimeters away from the phone. Then continue to observe the battery level of your phone.

After about 1 minute, the battery level of the mobile phone "poofed" again, rose a little, and became 30%.

Even so, Lu Han still didn't dare to conclude that it was this small energy body that charged the phone. Because although modern technology has invented the wireless charging base, people are all matching with mobile phones.

This small stone-like energy body can charge the mobile phone, which is amazing.

In order to continue the experiment, Lu Han put the small energy body back into the two-way storage wooden box, which was equivalent to cutting off the direct connection between the energy body and the mobile phone.

Lu Han observed the mobile phone, and after several minutes, he did not see the power of the mobile phone increase.

Now, it is basically certain that the increase in power is related to that energy body.

Just then, class ended.

Song Yingzhi walked to the back row, originally she didn't come to Xingshi to ask for the guilt, but when she sat down, she saw Lu Han's mobile phone with the screen lit up and 30% of the battery, Song Yingzhi's face suddenly changed.

"You...... Isn't there power on the phone?" asked Song Yingzhi.

The atmosphere is getting colder.

What does it mean, obviously the mobile phone has power, playing games with others in a double row, and retreating at the critical time of the team battle?
