Chen Zixuan's class still made Lu Lin gain a lot, although I don't know if the method he said will work, but he can try it when he breaks through to the fourth order martial artist.

Chen Zixuan left after giving them a lecture, and suddenly became normal, which made Lu Lin and the others, who were once his students, strange.

Although Chen Zixuan's lecture is very reasonable, he can't confirm it if he doesn't use it now, and he can only remember it in his heart.

......

In order to be able to start making space sacs earlier, Lu Lin is still trying to do it.

After another ten days of trying, Lu Lin didn't know how many times he had failed, and Lu Lin also summed up some useful methods.

First of all, to make a space sac, you must choose a dead object, and only then can the spiritual power see its internal structure. Secondly, the selected utensils must be of good material, such as those branches and ordinary stones, which simply cannot withstand the infusion of spatial vitality. Again, Lu Lin found that the spatial vitality could not pour too much into the artifact at one time, and it had to be slowly input through spiritual power.

The object of Lu Lin's current experiment is ordinary iron, which are all ores used to make ordinary utensils, and Lu Lin found a lot of iron-containing ores on the mountain behind the school.

Holding the iron ore in his hand, Lu Lin used his spiritual power to probe its internal structure, carefully feeling the internal mechanism of the iron block, Lu Lin found that there was actually a lot of space inside it, and found one of the places with a relatively large space, Lu Lin controlled the spatial vitality with his spiritual power and slowly entered.

Controlling the spatial energy to input iron was more consuming than Lu Lin had imagined, and it was the first time he had replaced the experimental subject with an iron block today.

The input of spatial energy should not be too fast, otherwise too much spatial energy will pour in and destroy the internal structure of the iron block, and this iron block will naturally be scrapped.

Carefully controlling the spatial vitality with spiritual power, this made Lu Lin's spiritual power consume sharply, and when Lu Lin's spiritual power was exhausted, the spatial vitality only occupied one-third of the area inside the iron block.

Without the control of Lu Lin's spiritual power, the spatial vitality inside the iron block immediately became unstable, and the entire iron block was also scrapped due to the violent impact of the spatial vitality.

Looking at the scrapped iron block in his hand, Lu Lin smiled dumbly, he knew that controlling the spatial vitality would consume spiritual power, so he would find the internal structure of the small point of the stone.

Now that his spiritual power has been exhausted, Lu Lin can only sit down and close his eyes to recover his spiritual power through the spiritual cultivation technique.

After recovering his spiritual power, Lu Lin once again used his spiritual power to observe the scrapped iron block in his hand. Sure enough, the internal structure of the iron block had been destroyed by the furious spatial energy.

Throwing away the scrapped iron block, Lu Lin picked up a relatively small stone next to him, and after observing its internal structure through spiritual power, he selected a relatively small internal space and began to experiment.

This time, Lu Lin finally got his wish and filled the space energy inside the iron block with the smaller space, and the next step was to use these space energy to use the martial arts space barrier inside the iron block.

Perceiving the spatial energy inside the iron block, Lu Lin became distressed again, you must know that releasing the space barrier is very consuming, and the energy in his body can only be released about ten times now, but how can the space energy in the iron block be able to release the space barrier?

The larger the area of the space barrier formed, the more vitality will be consumed, and the smaller the area, the less vitality will naturally be consumed, but Lu Lin has never tried to release such a small area of space barrier.

Whether it will succeed or not will not be known until you have tried it.

Lu Lin had to use the space energy inside the iron block to try to release the space barrier, but how could such a small amount of space energy be enough for the consumption of the space barrier, and the space barrier was consumed before it was formed.

There is only one last step left in the production of the space capsule, as long as the space barrier is spread out in the iron block, the space capsule can be formed. But in this last step, Lu Lin didn't know what to do.

......

Tian Feng's cultivation is now more difficult than before, he is not groping on his own now, Mu Chao, who is passing by here, will often point out some problems in his cultivation, and he will discuss with him when he has time.

In the battle between warriors, in addition to competing for vitality and martial arts, there is also one thing that is also very important, that is, combat experience.

Mu Chao was willing to learn from Tian Feng, which made Tian Feng very surprised, he had heard a lot of things related to Mu Chao after coming to school for so long.

He is the fifth-ranked master in the school's list, and it is said that he has broken through to the sixth order martial artist, and his cultivation is even more crazy, which is also the reason why Tian Feng admires him.

"Here, let me try your newfound moves. Mu Chao saw Tian Feng's moves, and his hands itched for a while.

"Senior Mu, be careful!" Tian Feng unceremoniously took the lead in attacking.

Tian Feng directly used the Wind Fist Technique, and the fist shadow in the sky blocked Mu Chao's retreat, but Mu Chao seemed to stay where he was, no matter how Tian Feng attacked, his fist couldn't hit Mu Chao's body at all.

The fist style went to hit one after another, but it couldn't touch a single hair of Mu Chao. Mu Chao once said that as long as Tian Feng can touch his clothes, Tian Feng wins, but every time he fails, he can't touch Mu Chao when he is exhausted.

Just as Mu Chao was dodging, Tian Feng played the second type of wind that was as fast as the wind, and the clothes and belts on Mu Chao's body floated uncontrollably.

Seizing the opportunity, Tian Feng grabbed the clothes and belts floating on Mu Chao's body with all his might, and just as Tian Feng was about to succeed, Mu Chao's body suddenly retreated backwards.

"Yes, I've become smarter, I know that I can't touch my body, and I want to grab my clothes and make me lose to you. Mu Chao, who was retreating, couldn't help laughing.

In their previous competition, Tian Feng would do his best to attack Mu Chao until he was exhausted, but he didn't expect Tian Feng to learn to be flexible this time, but Mu Chao, who was retreating, still didn't make a move.

As soon as he saw that Feng Yin's attack was effective, Tian Feng continued to attack.

But when Tian Feng used the wind again, he couldn't have that effect anymore, obviously Mu Chao had taken precautions.

Tian Feng's attack routines have long been known to Mu Chao, Tian Feng's previous attacks were all rampage, in the battle with Mu Chao, although he has never hit Mu Chao, but he also knows that it is much more flexible.

Tian Feng, who suddenly attacked frantically, calmed down, and above his fist, the pale yellow earth attribute vitality quickly condensed.

Tian Feng's fist was as if he was wearing an earthy yellow fist glove.

Looking at Tian Feng's fists, Mu Chao's fists behind his back also stretched out, and he could feel Tian Feng compressing the earth vitality of his body onto his fists.

When Tian Feng's fist turned from pale yellow to yellow, dense beads of sweat also condensed on Tian Feng's forehead.

"Senior Mu, be careful!"

Tian Feng finally threw his own fists, and two pale yellow fluctuations poured out from Tian Feng's fists.

Different from the wind in the wind fist method, the wind goes is to use the vitality to accelerate the speed of the punch, and there is an expanded punch wind of the double fist, and the impact formed is relatively scattered.

This time, Tian Feng's punching method was different, although it was also using the fluctuations of the double punches, but it compressed a large amount of earth vitality.

Although there is a word "wind" in the wind boxing method, it is not a wind attribute exercise, but more of a use of double fists, and the key to the wind boxing method lies in the word "disease".

Two pale yellow fluctuations rushed towards Mu Chao.

Although he was mentally prepared, Mu Chao still underestimated the speed of the two fluctuations, and the distance between the two was in front of Mu Chao in the blink of an eye.

Mu Chao didn't have time to dodge at all, and a layer of pale yellow halo was also covered in front of him, and the fluctuations that Tian Feng hit only caused a ripple after hitting that halo.

This is the first time Mu Chao has released his vitality, in the previous competition, Mu Chao has never used his vitality, but only dodged Tian Feng's attack with the power of **.

When he swung his fists, Tian Feng had already drained all the strength in his body, and he was gasping for breath at the moment.

"Boy, what kind of move are you, why is it so fast?"

Obviously, Mu Chao's move just now surprised Mu Chao, if he hadn't used his vitality to resist the attack, he might have really lost face in front of Tian Feng.
