She may claim whole world, but will get according to law. Question not that whether she can claim or not, question is what she can get.
Where landed property is concerned, as it is property in your name she can claim it at the time of divorcee proceedings under sec 24 & 25 of the hindu marriage act, which quoted bellow.

24.Maintenance Pendente lite and expenses proceedings.
Where in any proceeding under this Act it appears to the court that either the wife or the husband, as the case may be,
has no independent income sufficient for her or his support and
the necessary expenses of the proceeding, it may,
on the application of the wife or the husband, order the respondent to pay to the petitioner the expenses of the proceeding, and monthly during the proceeding such sum as, having regard to the petitioner's own income and the income of the respondent, it may seem to the court to be reasonable.
25. Permanent alimony and maintenance.
(1)Any court exercising jurisdiction under this Act may, at the time of passing any decree or at any time subsequent thereto, on application made to it for the purpose by either the wife or the husband, as the case may be, order that the respondent shall pay to the applicant for her or his maintenance and support such gross sum or such monthly or periodical sum for a term not exceeding the life of the applicant as, having regard to the
respondent's own income and
other property, if any,
the income and other property of the applicant,
the conduct of the parties and
other circumstances of the case, it may seem to the court to be just,
and any such payment may be secured,
if necessary, by a charge on the immovable property of the respondent.

First of all they have to claim under sec.24 & 25. If aduitry proved she will not get anything but your child may get maintenance. But one thing proving adultery is very difficult.
It is right to say “I will surrender my wife jewels in the court since I already filed divorce petition under adultery by my wife”. Do it when court orders.
Based on wife’s complaint police can file the case against husband but tell the police in writing that your case already sub judis.
Advice your fighting friends to come and claim at court. Now your rigidity is your weapons.
Though your baby is with his mother, but if adultery proved, then you can demand your baby’s guardianship, as it is not a safe custody of a adulterous mother.
Transfer or gift deed to your babies at this stage is not advisable. This will help her.
You are right on saying “But if I give to my wife, she will sell it and she will enjoy the money with her illegal husband”
You may prepare your ‘will’ in favour of your baby, where it can be mentioned that after reaching at the age of 18 years, they will be entitled to sale it.
You may sell your property also, but it will not be much more beneficial to you as because, if property taken into account, after sale value will be added. To escape it you have to show a low price in your land sale deed.
Your Lawyer will handle your case instead of you .No problem.
If you do not obey the court, then court may bring back you at India. But not your wife.
In case of your unableness, your lawyear will handle the matter.
No dismissal; no arrest warrant till your lawyear is there; in the meantime you can change your lawyear also.
If adultery is proved; then no money for her but otherwise court will go according to sec. 24 & 25. Way of calculation is in sec 25.
Do not give false information to the court, it will be contempt of court. If your salary reduces you have to pay low maintenance but for that a separate petition to be submitted.
