The simple and exquisite karma treasure chest fell in front of Ye Yu, and Ye Yu opened the treasure chest without hesitation.

A dazzling blue light shot out from the treasure chest in an instant, and you can see that countless items are changing in the blue light, and the size of the treasure chest is also getting bigger and smaller.

Finally, as the blue light gradually converged, the treasure chest disappeared, leaving only a long sword full of ancient charm on the spot.

The long sword is made of fine steel, and the body of the sword is engraved with talisman patterns. There is a Tai Chi pattern in the middle of the hilt. The blue sword spear emits a few bright lights. You can tell at a glance that it is not an ordinary person.

Ye Yu couldn't help but pick up the long sword, and instantly, the mechanical prompt sound of the system came from his ears.

"Congratulations to Ye Luohuan for opening the level 1 blue cause and effect treasure chest and obtaining the level 1 blue weapon - Tai Chi Sword."

"Item name: Tai Chi Sword."

"Item quality: Level 1 blue."

"Attribute introduction: Attack power level s, defense power level b, flexibility level a, hardness level a, toughness level s..."

"Introduction to the amplitude: There is a 60% increase in power for sword skills."

...

"Comprehensive item rating: S-level."

When Ye Yu saw the attributes of this long sword, he handed the Tai Chi sword to Lin Yueru for use without hesitation.

There is no doubt that this Tai Chi sword is the most suitable for Lin Yueru to use.

After Lin Yueru took Tongxuan Pill to improve her quality to purple, although the skills she used also increased to blue quality, her equipment was still green quality.

Due to the bucket effect, self, equipment, and skills, as long as one of these three has shortcomings, it will undoubtedly greatly reduce its strength. After Lin Yueru's quality has been improved to purple, she does not have a handy weapon. This is undoubtedly the biggest problem.

Equipment that is directly exchanged with causal value and system can only be exchanged for green quality at most, which is undoubtedly ineffective.

Now it's great. If someone wants to sleep, he will give him a pillow. This time, the Tai Chi sword opened in the Cause and Effect Treasure Box is undoubtedly a timely help.

Although what Ye Yu thought in his mind was that it would be best to have a level 1 purple-quality weapon that was worthy of Lin Yueru.

However, he also knew that purple-quality weapons were not that easy to obtain.

Having such a weapon of S-grade blue quality is already considered the best among the best.

Be contented and happy. Ye Yu had a very healthy mentality and handed over this Tai Chi sword to Lin Yueru.

As expected, Lin Yueru immediately fell in love with this Tai Chi sword as soon as she got it. She even felt a little cold-hearted in Ye Yu.

As a martial arts practitioner who has been practicing sword since childhood, Lin Yueru's desire for swords is far beyond Ye Yu's imagination.

Lin Yueru was using the Tai Chi Sword and after playing it for a few strokes, she felt that she had already become one with the Tai Chi Sword.

"Ye Lang! This sword is very suitable for me! I can feel it!" Lin Yueru said in front of Ye Yu with great excitement.

Ye Yu was also very happy to see Lin Yueru so happy. At the same time, he was much more relieved about Lin Yueru's safety.

After having this Tai Chi sword, Lin Yueru's strength has made another qualitative leap.

During this period, Ye Yu was not only working hard to improve his cultivation, but also trying every means to improve Lin Yueru's cultivation speed.

After Lin Yueru learned sword control with Li Xiaoyao, she was already considered a cultivator.

As a cultivator, Lin Yueru practices on her daily basis by absorbing the spiritual energy of heaven and earth.

But because the real world is no longer an era, there is no slight spiritual energy of heaven and earth that can be used by cultivators to practice.

Usually, Lin Yueru wants to practice, but can only return to the causal room to practice.

However, the quality of Ye Yu's causal room is obviously not too high. The spiritual energy of the heaven and earth in the room is very thin. If you want to practice in the causal room, your speed is very slow.

Ye Yu once tried to ask Luna, wanting to improve the quality of her causal room.

In the causal game, the causal room can also be cultivated.

In addition to expanding the size, various transformations can be carried out in the causal room.

Some people will transform the causal rooms into medicine gardens, some will transform the machining workshops, and some will even transform it into a warship factory, or a blessing in the world suitable for cultivation.

In short, every player can transform his or her causal room into various environments suitable for his or her professional practice by consuming the causal value according to his or her needs.

And this undoubtedly consumes a lot of causal value.

Therefore, for every player in the causal game, what is most lacking is of course the causal value.

Because, in the causal game, there are so many places where the causal value is needed.

Although Ye Yu once seemed to have a lot of causal value, in fact, when it comes to real flowers, he is a little short of money.

Not to mention, it would cost a lot to develop a causal room just by raising it. Ye Yu opened the display screen on the causal emblem and adjusted it to the interface for the causal room transformation, and was immediately dazzled by the dazzling array of transformation projects on it.

“Extend the causal room size:”

"Expand to 100 square meters: 100 causal value."

The initial size of each player's causal room is 30 square meters. If you want to expand to 100 square meters, you need to spend 100 causal values. But this is just the beginning. The next step is to increase the causal value consumed by expanding the size, which is a geometric multiple increase.

"Expanded to 500 square meters: 600 causal value."

"Expanded to 1000 square meters: 1500 causal value."

"Expanded to 2000 square meters: 4000 causal value."

...

"Expanded to 10,000 square meters: 50,000 causal value."

When Ye Yu saw it, he was speechless. After thinking about it, Ye Yu decided to consume 100 causal values ​​and expand the causal room to 100 square meters first.

After finding Luna, Ye Yu successfully transformed the expanded 100-square-meter causal room into a three-bedroom and one-living room home layout.

Ye Yu, Lin Yueru, Xiao Meiyan, and these three people each have a room. In this way, Ye Yu finally has his own room and will not sleep in the living room.

And this is just an option for expanding the size. The cost of other various transformation options is endless.

"Renovation of Level 1 machining workshop, renovation cost: 300 causal value."

"Renovation of Level 2 machining workshop, renovation cost: 1,000 causal value."

...

"Level 1 Spirit Spring, transformation cost: 400 causal value."

"Level 2 Spirit Spring, transformation cost: 1200 causal value."

...

"Level 1 Temple, renovation cost: 350 causal value."

"Level 2 Temple. Renovation cost: 1100 causal value."

...

...

There are so many ways to provide a variety of transformation projects according to the places suitable for practice in different professions.

And these without exception all require causal value consumption.

Since considering that a player may have multiple plot characters in different professions, similarly, a causal room can have multiple types of environments at the same time.

For example, Ye Yu can transform his room into a suitable environment for star refiners to practice. Lin Yueru's room into a suitable environment for cultivators to practice. Xiaomeiyan's room is transformed into an environment suitable for magical girls to practice.

In this way, the causal value required will naturally increase exponentially.

Of course, Ye Yu's star refining profession is quite special, and no environment is suitable for his cultivation. Yes, it is not something that his level can bear.

When Ye Yu checked whether there was an environment suitable for star refiners to practice, he only found one environment.

"The environments suitable for star refiners to practice include: the surface of the star and the core of the star, and the charges vary according to the mass of the star."

"Stars of the same size as the sun...

"The cost of surface transformation of level 6 stars: 10,000 causal value."

"The cost of level 8 star core transformation: 50,000 causal value."

...

Ye Yu was a little stunned when he saw this. Star Refiner does have an environment suitable for cultivation, but it is actually the surface of the star and the core of the star!

Is this a place where people can stay?

You should know that the surface temperature of the sun is as high as 6,000 degrees Celsius, and the core temperature is as high as 15 million degrees Celsius!

No wonder the transformation of the surface of a star requires level 6 players to carry out. I'm afraid that only level 6 players can survive or even practice in such a harsh environment.

In this way, level 8 players can survive in an extreme environment of 15 million degrees Celsius in the star core? Ye Yu couldn't imagine it.

Anyway, this is not the issue he needs to consider now.

In addition to perverted professions like Star Refiner, the profession of cultivator like Lin Yueru is much simpler.

Just replace a spiritual spring, it will be enough to change the concentration of spiritual energy in the world in the room, making it suitable for Lin Yueru's practice.

"Luna, help me transform Lin Yueru's room into her room." Ye Yu said to Luna without hesitation.

"Okay, master, this will consume you 400 causal points!"
